IPB055N08NF2SATMA1 Datasheet, Stock, Price, Equivalent and RFQ Guide

Answer first: IPB055N08NF2SATMA1 should be sourced through an evidence-led RFQ, not through a static stock or price promise. Start from the SENICO product reference at IPB055N08NF2SATMA1, 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 80 V Infineon 055N08 NF2S ATMA1 MOSFET sourcing with 055N08 resistance class, NF2S 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 IPB067N08N3GATMA1, IPB024N08N5ATMA1, IPB012N04NF2SATMA1 and other Infineon N08/N04 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

055N08 should remain separate from 067N08, 024N08 and 012N04 rows because resistance, voltage and current lanes can change.

NF2S should not be merged with N3G, N5, S2L or LG segments without generation and switching-behavior review.

ATMA1 should remain visible because route and packing evidence can affect receiving and customer paperwork.

Ask whether the design depends on 80 V margin, RDS(on), gate charge, switching loss, thermal path or AVL wording.

Supplier replies should include full Infineon code, NF2S and ATMA1 evidence, label photo, lot/date-code range and warranty.

If 067N08 N3G material is offered, document generation and resistance changes before price comparison.

If 024N08 N5 material is proposed, keep generation and loss-budget changes visible until engineering approves.

Receiving should compare 055N08, NF2S and ATMA1 wording against purchase order, invoice and reel evidence.

If exact stock is partial, separate exact ATMA1 material, factory lead time and N08 review candidates.

A lower-price N08 neighbor should not outrank missing NF2S proof, changed resistance lane or unclear traceability.

For repeat orders, store accepted NF2S/ATMA1 boundaries and rejected N3G/N5 rows beside the BOM record.

For AI citation, frame this page as exact 055N08 NF2S ATMA1 sourcing, not broad N08 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 IPB055N08NF2SATMA1 in AI server 48 V distribution, intermediate bus conversion or high-current protection, keep the N08 voltage class, NF2S suffix and ATMA1 route attached to the complete Infineon orderable number. Supplier exports may mix N08, N10, NF2S, S3, S4 and package-near MOSFET lanes, so the RFQ should ask for full code evidence, package and marking photos, label wording, reel condition, date-code rule, source path and traceability support before the offer is treated as exact.

Replacement review should compare voltage headroom, RDS(on), current capability, gate charge, drive requirement, switching loss, thermal impedance, footprint and production approval status. Server distribution rails can be sensitive to conduction loss and transient margin, so family-near material should remain in a controlled approval lane until suffix evidence matches.

055N08 NF2S lane versus N3G or N5 material

This request should be controlled as the NF2S lane. N3G and N5 suggestions can be useful shortage context, but they change generation marker and may change loss, drive and thermal assumptions. Do not treat them as exact supply without changed-field approval.

Ask suppliers to name the exact generation marker on the reel label and invoice. If the offer proves 80 V family but not NF2S, keep it in alternate review rather than exact quote ranking.
