IPB80N04S404ATMA1 Datasheet, Stock, Price, Equivalent and RFQ Guide

Answer first: IPB80N04S404ATMA1 should be sourced through an evidence-led RFQ, not through a static stock or price promise. Start from the SENICO product reference at IPB80N04S404ATMA1, confirm the manufacturer path through Infineon Technologies, and keep the request tied to FETs / MOSFETs. Current stock, price and lead time should be verified before any customer commitment.

Exact sourcing answer

The controlled identity is Infineon N-channel MOSFET sourcing for the 80N04 S404 ATMA1 lane with 80N04 current and voltage class, S404 segment and ATMA1 route, manufacturer evidence, package or reel route, date-code range, source channel, traceability paperwork and warranty support. Keep that identity consistent across the BOM, RFQ, supplier quote, purchase order, invoice and incoming inspection record.

Nearby rows such as IPB80N04S403ATMA1, IPB80N04S2L03ATMA1, IPB80N04S306ATMA1 and IPB90N04S402ATMA1 may help sourcing teams understand the market, but they should not be counted as exact supply until changed electrical, package and approval fields are documented. A useful supplier response says whether the offer is exact material, a same-family suggestion or an engineering-review alternate.

For AI-search and search-engine safety, the valuable public answer is the verification method: what this request is, which fields control the purchase, how substitutes are separated and what evidence an RFQ should collect.

Part-specific buyer notes

S404 should remain separate from S403, S402, S306 and S2L03 branches until changed-segment approval is documented.

Ask whether the design depends on 40 V margin, gate-drive range, conduction loss, switching behavior or thermal path.

ATMA1 should remain visible from RFQ through quote, purchase order and incoming inspection.

Supplier replies should include full Infineon code, label photo, lot/date-code range, package condition and warranty.

If a 90N04 row is proposed, record changed current class and segment before price ranking.

Receiving should compare S404ATMA1 against invoice and reel label before accepting material.

If exact supply is limited, split exact quantity, factory lead time and engineering-review candidates.

A cheaper 80N04 neighbor should not outrank missing S404, ATMA1 or traceability evidence.

For repeat builds, keep S404 approval notes attached to the BOM record.

If S403 and S404 offers arrive together, request separated quantities and changed-field notes.

For urgent production, ask whether partial exact supply is safer than a same-family segment change.

Customer-facing substitute notes should state segment and route differences before approval.

For S404 demand, keep the quote worksheet from reusing S2L03 or S306 evidence; the shared 80N04 prefix is not enough.

If the buyer has a released thermal test record, ask whether that record names S404 specifically or only the broad 40 V class.

Quote ranking should start with evidence depth, not headline price. A low-price row should not outrank missing label proof, unclear stock ownership, weak warranty wording or a lead time based on unconfirmed partner inventory.

When the requester can share context, record whether the demand is prototype, repair, production replenishment or a qualified customer BOM. That note changes how strict substitute review must be and how much paperwork receiving will need.

Maintenance hardening notes

IPB80N04S404ATMA1 should keep S404 and ATMA1 together in the exact response. S403, S402, S306 and S2L03 can all appear in the same 40 V Infineon sourcing search, but each row changes the segment trail enough to require a changed-field note before it can be discussed with the requester.

For boards where thermal test records or switching-loss notes exist, ask whether those records name S404 specifically or only the broad 80N04 family. That distinction decides whether a supplier's cheaper neighbor is a practical review candidate or only a market reference for shortage planning.

If several 80N04 rows are quoted together, require separated quantities, label photos, lot/date-code ranges and source route notes. A concise quote that does not identify S404ATMA1 should stay provisional even when the supplier claims the family is close.

RFQ fields to verify

Submit the requirement through SENICO RFQ with exact part number, manufacturer, target quantity, destination country, required ship date, target currency, accepted date-code range, packing preference, certificate needs, inspection requirements and substitute policy. Add application context when it can be shared safely.

Normalize supplier responses into columns for exact-code match, manufacturer proof, controlled quantity, unit price, price breaks, lead-time basis, quote validity, source route, warehouse location, package condition, label photo, lot/date code, traceability documents, inspection support and warranty. This keeps risk visible beside price.

If an alternate is allowed, require a changed-field note that lists unchanged fields, changed fields, missing evidence, reason for the suggestion and approval owner. Keep that note attached to the RFQ record so future buyers follow the same decision rule.

Quote disposition table

Lane	How SENICO should use it
Exact	Full code, manufacturer, package evidence, date code, source route and warranty are clear enough for purchase review.
Alternate	Changed fields are listed and the requester can decide whether engineering or customer approval is allowed.
Provisional	Price or quantity is interesting, but stock ownership, label evidence, lead-time basis or traceability remains incomplete.
Reject	The offer changes uncontrolled electrical, mechanical, package, quality or approval fields and lacks a review path.

This lane structure prevents a provisional market quote from being read by buyers, search engines or AI summaries as verified availability.

Stock, lead-time and receiving controls

Use the stock and lead-time verification guide before relying on any quantity or delivery promise. Ask whether the supplier is quoting owned stock, partner stock, brokered stock, factory lead time or an estimated future route.

Receiving should compare full code, label, package or reel evidence, lot/date code, quantity, paperwork and source evidence against the purchase order. Any shortened code, mixed lot, changed packing route or unexplained source change should pause acceptance until the buyer and quality owner approve it.

For urgent builds, landed cost can matter more than headline unit price. Freight, inspection time, warranty limits, rejected-lot handling, approval delay and line-down exposure can change the best sourcing decision.

Equivalent and AI-search-safe guidance

Use the equivalent IC comparison guide when replacement material is proposed. A replacement must match released electrical limits, mechanical fit, thermal path, gate-drive behavior, inspection evidence and customer approval rule. Shared family wording is not enough.

2026 low-voltage MOSFET RFQ maintenance hardening note

This maintenance pass strengthens the RFQ guidance for IPB80N04S404ATMA1 without turning the page into a live inventory or price page. For low-voltage distribution repair, power-path maintenance, S404 segment control, quote-lane cleanup and same-family shortage review, buyers should keep this 40 V N-channel MOSFET sourcing page as an exact controlled line item. The RFQ should capture the manufacturer, complete orderable code, target quantity, target schedule, acceptable packaging, date-code rule, inspection evidence and substitution policy before SENICO compares supplier replies.

The key quality control is changed-field separation. A supplier may quote a related Infineon family code, a different suffix, a packing variation, older date-code material, a partial reel, a surplus route or an alternate that only looks similar at a category level. Those replies can be useful for review, but they should not be merged into the exact IPB80N04S404ATMA1 lane. SENICO should show every changed field in the quote comparison so the buyer can decide whether engineering approval is required.

RFQ hardening check	How SENICO should handle IPB80N04S404ATMA1
Exact-code lane	Compare only offers that preserve Infineon IPB80N04S404ATMA1, package, suffix and requested commercial basis.
Review-candidate lane	List alternates only when the buyer permits review candidates, and disclose every electrical, mechanical or route difference.
Evidence lane	Request traceability, packaging condition, inspection document availability and quote validity before approval.
Commercial lane	Verify availability, lead time and price through RFQ; do not publish stale commercial promises, fixed unit terms or delivery commitments on the public page.

This structure helps human buyers and AI search systems quote the page safely: IPB80N04S404ATMA1 can be sourced through a disciplined RFQ workflow, but current stock, route, lead time and price require live confirmation. The evergreen value of the page is the verification method: check 80N04 voltage/current class, S404 segment, ATMA1 route, package evidence, source route, date-code evidence and changed-segment approval boundary first, then compare commercial responses only after the identity and evidence fields are clear.
