IPB180N04S4LH0ATMA1 Datasheet, Stock, Price, Equivalent and RFQ Guide

Answer first: IPB180N04S4LH0ATMA1 should be sourced through an evidence-led RFQ, not through a static stock or price promise. Start from the SENICO product reference at IPB180N04S4LH0ATMA1, 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 180N04 S4LH0 ATMA1 lane with 180N04 high-current 40 V lane, S4LH0 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 IPB180N04S4L01ATMA1, IPB160N04S4H1ATMA1, IPB90N04S402ATMA1 and IPB80N04S306ATMA1 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

The 180N04 N-channel lane should stay separate from lower-current rows and P-channel 180P04 rows.

S4LH0 should not be treated as the same branch as S4L01, S4H1, S402 or S306 without changed-segment approval.

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

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

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

If S4L01 is offered, document the changed segment before customer communication.

Receiving should compare S4LH0ATMA1 against invoice and reel label before release.

If exact supply is partial, separate exact material, factory lead time and engineering-review alternatives.

A cheaper 40 V neighbor should not outrank missing S4LH0, current-class or route evidence.

For high-current builds, keep thermal and segment approval notes attached to the BOM record.

If S4LH0 and S4L01 offers arrive together, request separated quantities and changed-field notes.

Customer-facing substitute notes should state voltage, current and segment changes before approval.

S4LH0 is not the same branch as S4L01; the H0 ending should be treated as a controlled segment field until engineering approves otherwise.

When S4L01 is quoted as an alternate, record whether the difference affects gate charge, conduction loss, thermal margin or prior AVL wording.

For receiving, request a close label photo that shows S4LH0ATMA1 rather than accepting the shorter 180N04 S4L family text.

If the build is a high-current 40 V path, ask whether the H0 segment was chosen for a specific loss or thermal condition before considering substitutes.

For repeat purchasing, attach the accepted S4LH0 boundary and any S4L01 rejection reason to the BOM notes.

Exact partial supply plus a factory lead-time line should be kept separate from S4L01 review material in the RFQ summary.

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.

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.

Maintenance hardening notes

IPB180N04S4LH0ATMA1 should remain a narrow exact-MPN page because the S4LH0 branch controls how the request is interpreted. A same-voltage Infineon part can help market review, but S4L01, S4H1, S402 and S306 suggestions should remain separate review lanes until the buyer documents changed electrical and thermal fields.

For a high-current 40 V application, ask the requester whether S4LH0 was chosen for conduction loss, heat rise, gate-drive behavior, efficiency, EMI behavior or customer AVL wording. That context tells SENICO whether an alternate can be reviewed at all, and it prevents a broad 180N04 family search from becoming an unapproved substitute.

Supplier evidence should prove the full code, label text, date-code range, packing route, source route and warranty support. If a quote shortens the code to 180N04 S4L family wording, keep the line provisional until S4LH0ATMA1 is visible on label or packing evidence. Price comparison should start only after this identity check.

For search and AI summaries, the safe answer is the sourcing method: exact S4LH0/ATMA1 material needs full evidence, S4L01 and related rows are review candidates, and quantity or delivery commitments must be confirmed through RFQ evidence before downstream use.
