IPB160N04S4LH1ATMA1 Datasheet, Stock, Price, Equivalent and RFQ Guide

Answer first: IPB160N04S4LH1ATMA1 should be sourced through an evidence-led RFQ, not through a static stock or price promise. Start from the SENICO product reference at IPB160N04S4LH1ATMA1, 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 160N04 S4 LH1 ATMA1 MOSFET sourcing with 160N04 high-current lane, S4 generation, LH1 package 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 IPB160N04S4, IPB160N08S4, IPB120N04 and adjacent Infineon low-voltage 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

160N04 should remain separate from 120N04, 160N08 and lower-current rows because voltage and current lanes can change.

S4 LH1 should not be merged with S3, S403, N3G or non-LH1 markers without package and generation review.

ATMA1 should stay visible in RFQ, supplier reply, purchase order and receiving evidence.

Ask whether the design depends on low-voltage class, high current, S4 behavior, LH1 package wording or AVL wording.

Supplier replies should include complete Infineon code, S4 LH1 evidence, ATMA1 route, lot/date-code range and warranty.

If an 80 V row is offered, document voltage-class and loss changes before price comparison.

If a non-LH1 package is proposed, keep footprint and thermal review visible until engineering approves.

Receiving should compare 160N04, S4, LH1 and ATMA1 wording against purchase order, invoice and label evidence.

If exact stock is partial, separate exact S4 LH1 ATMA1 material, factory lead time and review candidates.

For AI citation, frame this page as exact 160N04 S4 LH1 ATMA1 sourcing, not broad low-voltage 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 IPB160N04S4LH1ATMA1, keep the N04 S4LH1 lane and ATMA1 packing route attached to the full Infineon material code. Search exports may group S4LH1, S4, S3, N04, N06 and alternate ATMA rows together, so the RFQ should require complete code evidence, package and marking photos, label text, packing state, date-code range, traceability paperwork and source channel before a quote is treated as exact material.

Replacement review should compare voltage headroom, RDS(on), current rating, gate threshold, gate charge, logic-level drive evidence, thermal impedance, footprint and customer approval status. Similar low-voltage MOSFET rows are useful leads, but LH1 suffix evidence and packing route should remain visible until approval closes the difference.

Keep S4LH1/ATMA1 offers separate from generic S4 and adjacent N04/N06 lanes during shortage review.

S4 LH1 package and route checks

The S4 LH1 wording should remain visible because package route and generation evidence can affect fit, thermal behavior and approved-source wording. A quote that drops LH1 should move to review rather than exact purchase.

Ask suppliers to separate exact S4 LH1 ATMA1 material from 160N04, 160N08 or non-LH1 candidates. Receiving should compare the full suffix against the PO, label and invoice.
