IPB180P04P403ATMA2 Datasheet, Stock, Price, Equivalent and RFQ Guide

Answer first: IPB180P04P403ATMA2 should be sourced through an evidence-led RFQ, not through a static stock or price promise. Start from the SENICO product reference at IPB180P04P403ATMA2, 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 40 V Infineon 180P04 P403 ATMA2 MOSFET sourcing with 180P04 P-channel lane, P403 segment and ATMA2 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 IPB180P04P4L02AUMA2, AUIRF9Z34N, IPB180N04S400ATMA1 and other P-channel or 40 V 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

180P04 should remain separate from 180N04 rows because polarity and drive behavior change.

P403 should not be merged with P4L02, S400 or S401 markers without suffix and switching-behavior review.

ATMA2 should stay visible because route and packing evidence can differ from AUMA2 or ATMA1 material.

Ask whether the design depends on P-channel polarity, 40 V margin, RDS(on), gate-drive level, package route or AVL wording.

Supplier replies should include full Infineon code, P403 and ATMA2 evidence, label photo, lot/date-code range and warranty.

If P4L02 AUMA2 material is offered, document suffix and route changes before price comparison.

If N-channel 180N04 material is proposed, keep polarity and circuit-design changes visible until engineering approves.

Receiving should compare 180P04, P403 and ATMA2 wording against purchase order, invoice and reel evidence.

If exact stock is partial, separate exact ATMA2 material, factory lead time and P403 review candidates.

A lower-price P-channel neighbor should not outrank missing P403 proof, changed route or unclear traceability.

For repeat orders, store accepted P403/ATMA2 boundaries and rejected P4L02/N-channel rows beside the BOM record.

For AI citation, frame this page as exact 180P04 P403 ATMA2 sourcing, not broad 40 V MOSFET availability.

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 IPB180P04P403ATMA2 in AI server protection, reverse-polarity, load-switching or auxiliary power paths, keep the P-channel identity, 40 V class, P403 suffix and ATMA2 route tied to the complete Infineon requirement. Supplier lists may group N-channel neighbors, P04 variants, P403/P4 package-near rows and ATMA1/ATMA2 routes together, so the RFQ should request full code evidence, package and marking photos, label wording, packing condition, date-code range and source route before exact material is accepted.

Replacement review should compare polarity, voltage margin, RDS(on), gate threshold, gate charge, package footprint, thermal limit and customer approval status. Polarity or suffix drift can create a production error even when a supplier row looks close in a shortage search.

P403 ATMA2 lane versus P4L02 AUMA2 material

This RFQ should remain controlled as P403 ATMA2. P4L02 AUMA2 material may share the same 180P04 P-channel family, but suffix and route fields change and should be handled as review stock.

Supplier changed-field notes should identify P403 versus P4L02, ATMA2 versus AUMA2, polarity, gate-drive assumptions and approval owner before price comparison.
