AUIRF2804 Datasheet, Stock, Price, Equivalent and RFQ Guide

Answer first: AUIRF2804 should be sourced through an evidence-led RFQ, not through a static stock or price promise. Start from the SENICO product reference at AUIRF2804, 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 AUIRF2804 automotive MOSFET sourcing with AUI automotive prefix, RF2804 identity and package or route evidence, 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 IRF2804, AUIRF3205, AUIRF3305, AUIRF3805 and other automotive high-current MOSFET 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

The AUI prefix should remain visible because automotive or qualified-source expectations may be tied to that route.

Ask whether the design is limited by voltage margin, high-current conduction loss, avalanche behavior, package thermal path or customer AVL approval.

Commercial IRF2804 rows can be market context, but they should not be blended with exact AUIRF demand without approval.

AUIRF3205, AUIRF3305 and AUIRF3805 suggestions require electrical, package and route comparison before quote ranking.

Supplier replies should show full code, Infineon identity, label photo, date-code range, package condition, ownership and warranty.

For automotive service demand, ask whether exact markings or route evidence are required for incoming inspection.

Receiving should compare the AUI prefix and RF2804 identity against purchase order and reel evidence before release.

If exact stock is scarce, separate exact quantity from commercial or same-family suggestions.

A lower-price commercial row should remain provisional without changed-field documentation.

The public page should explain evidence-led RFQ handling instead of promising live availability.

For automotive service demand, record whether the AUI route is mandatory or whether commercial IRF material can be reviewed.

If a same-family automotive row is offered, compare avalanche, thermal and package evidence before ranking price.

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.

Maintenance hardening notes

For AUIRF2804, keep the AUI automotive identity and RF2804 code together from RFQ through receiving. Commercial IRF2804 offers can be useful market references, but they are not exact supply unless the buyer accepts the changed qualification route, label evidence and customer approval impact.

Ask suppliers to separate exact AUIRF2804 material from AUIRF3205, AUIRF3305 or AUIRF3805 suggestions. A strong response should identify changed voltage, current, avalanche, package or automotive-route fields and provide label photos, lot/date-code range, source route and warranty wording before commercial ranking.

For service or repair demand, record whether exact AUI-marked material is mandatory or whether a commercial-row review is permitted. That decision should sit with the quote record so future buyers do not reopen the same automotive-vs-commercial question.

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.
