IPB180N04S302ATMA1 Datasheet, Stock, Price, Equivalent and RFQ Guide

Answer first: IPB180N04S302ATMA1 should be sourced through an evidence-led RFQ, not through a static stock or price promise. Start from the SENICO product reference at IPB180N04S302ATMA1, confirm the manufacturer path through Infineon Technologies, and keep the request tied to FETs and MOSFETs. Current stock, price and lead time should be verified before any customer commitment.

Exact sourcing answer

The controlled identity is Infineon 40 V MOSFET sourcing for the 180N04 S302 ATMA1 lane with 180N04 high-current class, S302 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 IPB120N04S302, IPB180N04S401ATMA1, IPB80N04S204ATMA1 and other Infineon 40 V MOSFET rows 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

180N04 should remain separate from 120N04 and 80N04 rows because current class, resistance and heat-rise margin can change.

S302 should not be merged with S401 or S204 segments without electrical and approval review.

ATMA1 should stay visible because route and packing evidence can affect purchasing and receiving.

Ask whether the design depends on high-current 40 V margin, conduction loss, switching loss, thermal pad behavior or customer AVL wording.

Supplier replies should include full Infineon code, reel label photo, lot/date-code range, S302 and ATMA1 evidence, source ownership and warranty.

If IPB120N04S302 is offered, document changed current class before price comparison.

If S401 or S204 material is proposed, keep it in segment-review until gate-charge, loss and thermal differences are approved.

Receiving should compare 180N04, S302 and ATMA1 wording against purchase order, invoice and reel label evidence.

If exact stock is partial, separate exact ATMA1 material, factory lead time and 40 V review candidates.

A lower-price N04 row should not outrank missing S302 proof, changed current class or unclear source ownership.

For high-current boards, ask whether heat-rise or EMI testing was tied to the 180N04 class before accepting alternates.

Customer-facing substitute notes should state voltage class, current class, segment, route and approval changes before any alternate is presented.

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

For IPB180N04S302ATMA1, keep the 40 V N04 class, S3 technology marker, 02 suffix and ATMA1 packing route in one exact-material requirement. Supplier lists can blend S302, S303, S4, S4L, N03, N04 and IPB180 package-near rows, so the RFQ should request the full Infineon code, package and top-marking photos, label wording, reel or tube condition, date-code range, traceability support and source route.

Equivalent review should compare voltage headroom, RDS(on), current rating, gate charge, drive requirement, thermal impedance, footprint and customer AVL status. A suffix-near N04 row may be useful for shortage discovery, but it should remain pending until package, suffix and approval evidence are recorded.

Keep S302/ATMA1 exceptions separate from S303 and S4L alternatives in the sourcing worksheet.
