IPB90N06S404ATMA2 Datasheet, Stock, Price, Equivalent and RFQ Guide

Answer first: IPB90N06S404ATMA2 should be sourced through an evidence-led RFQ, not through a static stock or price promise. Start from the SENICO product reference at IPB90N06S404ATMA2, 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 60 V Infineon N-channel MOSFET sourcing for the S404 ATMA2 row with 90N06 voltage/current family, S404 electrical 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 IPB90N06S402, IPB90N06S403, IPB90N06S4L07, IPB80N06S209 and ATMA1/ATMA2 route variants 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 S404 segment should stay separate from S402 and S403 because a close suffix can still change electrical and approval assumptions.

Ask whether the design is limited by 60 V margin, conduction loss, switching behavior, thermal pad performance or released BOM history.

ATMA2 is a controlled route field; ATMA1 material should be quoted as a route variant until the requester accepts that change.

S4L07 and S209 rows can support shortage research, but they require changed-field review before they become alternatives.

Supplier evidence should include full code, Infineon route, label photo, date-code range, package condition, traceability and warranty support.

If the supplier quotes factory lead time, record quote validity, allocation risk and whether the route can remain ATMA2 across future lots.

Receiving should compare S404ATMA2 against reel label, invoice, packing evidence and purchase order before release.

For urgent production, split exact stock from engineering-review suggestions so planners do not overcount usable quantity.

If the requester accepts substitutes, compare RDS(on), gate charge, avalanche or thermal behavior, package and approval owner.

A public sourcing page is safest when it explains evidence checks instead of converting old market data into a stock claim.

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

For IPB90N06S404ATMA2, keep the 90N06 class, S404 segment and ATMA2 route visible as the exact procurement lane. Nearby S402, S405, 80N06 or 90N04 rows should stay in review lanes until changed voltage, current, resistance, package route and customer approval fields are named.

Ask suppliers to quote exact S404ATMA2 material separately from ATMA1 route variants or same-family S4 suggestions. A useful response should include full Infineon code, label photo, source route, lot/date-code range and a changed-field note before price breaks are compared.

For repeat demand, store the accepted S404ATMA2 boundary with the BOM and quote record. This prevents future buyers from accepting a shortened 90N06 title when the real approval depends on both the S404 segment and route evidence.

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.
