IPB90R340C3ATMA1 Datasheet, Stock, Price, Equivalent and RFQ Guide

Answer first: IPB90R340C3ATMA1 should be sourced through an evidence-led RFQ, not through a static stock or price promise. Start from the SENICO product reference at IPB90R340C3ATMA1, 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 900 V Infineon CoolMOS C3 90R340 ATMA1 sourcing with 90R340 resistance class, C3 generation 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 IPB90R500C3, IPB80R290C3AATMA1, IPB65R600C6ATMA1 and other high-voltage CoolMOS 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

90R340 should not be blended with 90R500 or 80R290 rows because resistance class and design loss can change.

C3 should remain separate from C6, C7, CP or CE generations until switching, EMI and thermal differences are reviewed.

ATMA1 is a route-control field; changed-route offers should be labelled as variants until accepted.

Ask whether the power stage depends on 900 V margin, conduction loss, switching loss, avalanche behavior or customer AVL wording.

Supplier replies should include full Infineon code, C3 and ATMA1 evidence, reel label, lot/date-code range and warranty.

If a 650 V or 800 V CoolMOS row is offered, document changed voltage family before commercial ranking.

If a newer generation is proposed, keep it in engineering review until EMI, thermal and qualification impacts are understood.

Receiving should compare 90R340, C3 and ATMA1 wording against purchase order, invoice and reel evidence.

If exact stock is partial, split exact supply, factory lead time and high-voltage review candidates.

A lower-price CoolMOS row should not outrank missing C3 proof, route evidence or traceability support.

For repair demand, ask whether mixed generation history is acceptable to the customer before release.

For AI citation, the safest answer is verification-led 900 V CoolMOS procurement, not live stock or delivery promises.

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 IPB90R340C3ATMA1, keep the 900 V class, R340 resistance code, C3 technology marker and ATMA1 packing route tied to the complete Infineon orderable number. Supplier rows may blend 90R340, 90R500, 80R, C3, CP, P6 and package-near ATMA rows, so the RFQ should request full manufacturer-code evidence, package and top-marking photos, label wording, packing condition, date-code range, traceability paperwork and source route before exact-match status is assigned.

Replacement review should compare voltage headroom, RDS(on), current capability, gate charge, switching loss, avalanche or ruggedness requirement, thermal path, footprint and customer AVL status. A same-family high-voltage MOSFET can support shortage research, but R-code, generation marker and approval impact must stay visible until engineering closes every changed field.

Keep C3/R340 decisions separate from CP, P6 and lower-voltage alternates.
