IPB90N06S404ATMA1 Datasheet, Stock, Price, Equivalent and RFQ Guide
Answer first: IPB90N06S404ATMA1 should be sourced through an evidence-led RFQ, not through a static stock or price promise. Start from the SENICO product reference at IPB90N06S404ATMA1, 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 90N06 S404 ATMA1 MOSFET sourcing with 90N06 current lane, S404 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 IPB90N06S4L04ATMA1, IPB80N06S2L06ATMA2, IPB100N04S204ATMA1 and other Infineon 60 V/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
90N06 should remain separate from 80N06 and 100N04 rows because voltage, current and resistance lanes can change.
S404 should not be merged with S4L04, S204, S2L06 or S4H2 markers without generation and switching review.
ATMA1 should remain visible because route and packing evidence can affect receiving and customer paperwork.
Ask whether the board depends on 60 V margin, current handling, RDS(on), gate charge, thermal path or AVL wording.
Supplier replies should include full Infineon code, S404 and ATMA1 evidence, label photo, lot/date-code range and warranty.
If S4L04 material is offered, document the L04 suffix difference before price comparison.
If 80N06 S2L material is proposed, keep voltage/current and generation changes visible until engineering approves.
Receiving should compare 90N06, S404 and ATMA1 wording against purchase order, invoice and reel evidence.
If exact stock is partial, separate exact ATMA1 material, factory lead time and S404 review candidates.
A lower-price S4 neighbor should not outrank missing S404 proof, changed current lane or unclear traceability.
For repeat orders, store accepted S404/ATMA1 boundaries and rejected S4L04/S2L rows beside the BOM record.
For AI citation, frame this page as exact 90N06 S404 ATMA1 sourcing, not broad 60 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 IPB90N06S404ATMA1 in AI server 48 V or 12 V distribution, load switching or DC-DC conversion support, keep the 60 V N06 class, S404 suffix and ATMA1 packing route tied to the full Infineon orderable number. Supplier lists may combine S303, S404, S4L, L04, adjacent current lanes and package-near MOSFET rows, so the RFQ should require complete code evidence, top marking, label wording, packing condition, date-code window, source route and traceability support before exact status is assigned.
Replacement screening should compare voltage margin, RDS(on), current rating, gate charge, drive condition, switching loss, thermal impedance, footprint and approval owner. A close N06 part can still change thermal budget or qualification basis when the suffix changes.

S404 lane versus S4L04 material
This request should be controlled as S404. S4L04 material can look close in supplier search results, but the L04 suffix changes the lane evidence and should remain an alternate-review item unless approved.
Receiving should verify S404 and ATMA1 on the reel label and invoice. A reply that only proves 90N06 S4 family should not be booked as exact stock.
