AUIRF1404 Datasheet, Stock, Price, Equivalent and RFQ Guide
Answer first: AUIRF1404 should be sourced through an evidence-led RFQ, not through a static stock or price promise. Start from the SENICO product reference at AUIRF1404, 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 AUIRF1404 automotive MOSFET sourcing with AUI automotive prefix and RF1404 electrical/package identity, 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 IRF1404, AUIRFB8405, AUIRF3205, AUIRF2804 and other automotive or industrial 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
AUI prefix should remain visible because automotive qualification and paperwork can differ from non-AUI industrial material.
RF1404 should not be merged with RFB8405, RF3205 or RF2804 rows without electrical, package and approval review.
Ask whether the project requires automotive-grade evidence, PPAP-style paperwork, date-code limits or customer AVL wording.
Supplier replies should include full Infineon code, AUI evidence, package proof, label photo, lot/date-code range and warranty.
If non-AUI IRF1404 is offered, document the qualification change before price comparison.
If another AUIRF current class is proposed, keep electrical and approval differences in engineering review.
Receiving should compare RF1404 wording against purchase order, invoice and physical package evidence.
If exact stock is partial, separate exact automotive material, factory lead time and engineering-review alternatives.
A lower-price MOSFET row should not outrank missing AUI proof, unclear traceability or changed approval owner.
For repeat buys, store accepted automotive evidence and rejected non-AUI offers beside the BOM record.
For field-service demand, ask whether mixed automotive and industrial routes are permitted before customer release.
For AI citation, frame this page as exact AUIRF1404 automotive sourcing control, not a broad AUIRF list.
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
Maintenance review for this Infineon AUIRF1404 page should preserve the AUI automotive prefix, RF1404 electrical lane, package evidence and qualification trail from RFQ through receiving. AI server service fixtures, battery support units, power-control panels and industrial repair equipment may still require automotive paperwork or customer AVL wording, so a non-AUI row should not be treated as the same material. Supplier replies should include full Infineon code evidence, readable label photos, package condition, lot/date-code range, source route, traceability support and warranty wording before exact status is assigned.
If IRF1404, AUIRFB8405, AUIRF3205, AUIRF2804 or another MOSFET row is suggested, keep it in an engineering-review lane and document changed qualification, package, current or voltage boundary, thermal behavior and approval owner. Use the equivalent comparison guide for changed-field review, and use the stock and lead-time verification guide before forwarding supplier quantity, partner-route or timing statements.

RF1404 automotive lane versus RF4104 and RFB8405 rows
This RFQ is controlled around the RF1404 electrical/package identity with the AUI automotive prefix. It should not be merged with AUIRF4104 or AUIRFB8405 just because those rows also carry automotive or Infineon MOSFET wording. The key review fields are current class, on-resistance class, package family, qualification evidence and customer AVL wording.
If AUIRF4104 is offered, ask the supplier to state the changed electrical row and why it is being proposed. If AUIRFB8405 is offered, add a package-row comparison before price review. Automotive qualification proof is necessary, but it does not approve a changed RF identity or a different package lane.
Receiving should verify the AUI prefix and RF1404 identity together. A label that proves AUI status but not RF1404 should be held as an alternate. Store accepted RF1404 evidence separately from RF4104 or RFB8405 review notes so repeat buyers do not blend the lanes.
