IPB180N04S4L01ATMA1 Datasheet, Stock, Price, Equivalent and RFQ Guide

Answer first: IPB180N04S4L01ATMA1 should be sourced through an evidence-led RFQ, not through a static stock or price promise. Start from the SENICO product reference at IPB180N04S4L01ATMA1, 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 S4L01 ATMA1 lane with 180N04 high-current 40 V lane, S4L01 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 IPB160N04S4H1ATMA1, IPB180P04P4L02ATMA1, 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 P-channel 180P04 rows and lower-current N-channel rows.

S4L01 should not be treated as the same branch as S4H1, S402, S403 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, ownership and warranty.

If a P-channel or 60 V neighbor is offered, document polarity or voltage change before customer communication.

Receiving should compare S4L01ATMA1 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 current-class, segment or route evidence.

The public page should remain evidence-focused and avoid unverified availability commitments.

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

If S4L01 and S4H1 offers arrive together, request separated quantities and changed-field notes.

For urgent demand, record whether exact partial supply is safer than a changed-current option.

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

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

IPB180N04S4L01ATMA1 should not be collapsed into a broad IPB180 or 40 V MOSFET bucket. The N-channel identity, 180N04 current class, S4L01 segment and ATMA1 route each control how a supplier response should be accepted, held for review or rejected.

Polarity is a hard boundary here: P-channel neighbors and similar-looking 40 V rows require explicit engineering approval before they can be discussed as substitutes. Even same-family Infineon options should list changed thermal, resistance, package and gate-drive fields before price is compared.

For urgent replenishment, exact partial supply may be safer than a larger changed-current offer if the board has thermal or customer approval constraints. The RFQ should make that tradeoff visible through evidence columns instead of relying on a short stock-and-price answer.

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.
