IPB052N04NGATMA1 Datasheet, Stock, Price, Equivalent and RFQ Guide

Answer first: IPB052N04NGATMA1 should be sourced through an evidence-led RFQ, not through a static stock or price promise. Start from the SENICO product reference at IPB052N04NGATMA1, 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 052N04 NG ATMA1 MOSFET sourcing with 052N04 current/resistance class, NG generation marker 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 IPB080N04S204ATMA2, IPB100N04S2L03ATMA2, IPB052N06N and other Infineon N04/N06 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

052N04 should remain separate from 080N04 and 100N04 rows because current class and resistance behavior can change.

The 40 V family should not be blended with N06 rows without voltage-margin and gate-drive review.

NG should stay separate from S2L, S204 and S4 rows until generation and switching differences are approved.

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

Ask whether the design depends on 40 V headroom, conduction loss, gate charge, thermal behavior or customer AVL wording.

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

If a higher-current N04 row is offered, document current/resistance changes before price comparison.

If ATMA2 or no-route material is proposed, keep it in route review until receiving differences are approved.

Receiving should compare 052N04, NG and ATMA1 wording against purchase order, invoice and label evidence.

If exact stock is partial, separate exact ATMA1 material, factory lead time and N04 review candidates.

A lower-price N04 row should not outrank missing NG proof, route evidence or traceability support.

For repeat orders, store accepted NG/ATMA1 boundaries and rejected S2L/S204 rows beside the BOM record.

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 IPB052N04NGATMA1, keep the 40 V N04 class, NG suffix and ATMA1 packing route tied to the complete Infineon orderable code. Supplier exports may group NG, N3, S3, S4 or package-adjacent IPB rows together, so the RFQ should require full manufacturer code evidence, package photo, top marking, label text, packing state, date-code window and source route before the offer is marked exact.

Alternate screening should compare voltage headroom, RDS(on), current rating, gate charge, logic-level drive requirement, thermal path, footprint and production approval status. A close N04 family match can still be unsuitable when suffix, package or packing route changes affect the validated BOM. Keep exact material, pending-evidence rows and engineering alternates in separate lanes.

Carry every NG or ATMA1 deviation into the next sourcing review.
