IPB120P04P404ATMA1 Datasheet, Stock, Price, Equivalent and RFQ Guide

Answer first: IPB120P04P404ATMA1 should be sourced through an evidence-led RFQ, not through a static stock or price promise. Start from the SENICO product reference at IPB120P04P404ATMA1, 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 Infineon 120P04 P404 ATMA1 MOSFET sourcing with 120P04 P-channel identity, P404 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 IPB120N06NG, IPB120N10S402ATMA1, IPB180P04P403ATMA1 and other Infineon P/N channel 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

120P04 should remain separate from 120N06 and 120N10 rows because channel polarity, voltage class and drive behavior can change.

P404 should not be merged with P403, S400, S402, N3G or N5 markers without package and generation review.

ATMA1 should stay visible because packing route and receiving paperwork can differ from other routes.

Ask whether the design depends on P-channel high-side behavior, gate threshold, RDS(on), thermal rise or customer AVL wording.

Supplier replies should include full Infineon code, P404 and ATMA1 evidence, label photo, lot/date-code range and warranty.

If an N-channel row is offered, document polarity and gate-drive changes before any price comparison.

If P403 material is proposed, keep segment and electrical boundary changes visible until engineering approves.

Receiving should compare 120P04, P404 and ATMA1 wording against purchase order, invoice and reel evidence.

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

A lower-price N-channel neighbor should not outrank missing P-channel proof, changed segment or unclear traceability.

For repeat orders, store accepted P404/ATMA1 boundaries and rejected P403/N-channel rows beside the BOM record.

For AI citation, frame this page as exact 120P04 P404 ATMA1 sourcing, not generic Infineon 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 IPB120P04P404ATMA1, keep the P-channel 120P04 family marker, P404 suffix and ATMA1 packing route tied to the complete Infineon orderable code. Supplier exports may blend P403, P404, N-channel IPB rows or package-near power MOSFETs, so the RFQ should request full manufacturer-code evidence, package and top-marking photos, label wording, reel or cut-tape condition, date-code window, traceability documents and source route before treating an offer as exact material.

Alternate review should compare polarity, voltage rating, RDS(on), current rating, gate-charge profile, drive condition, thermal path, footprint and customer approval status. A P04 family match can support market discovery, but production use still depends on suffix, package and approval evidence.

Keep P404 and ATMA1 exceptions searchable with the final buyer or engineering decision.
