AUIRF9Z34N Datasheet, Stock, Price, Equivalent and RFQ Guide
Answer first: AUIRF9Z34N should be sourced through an evidence-led RFQ, not through a static stock or price promise. Start from the SENICO product reference at AUIRF9Z34N, 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 automotive P-channel AUIRF9Z34N MOSFET sourcing with AUIRF automotive prefix, 9Z34N P-channel lane and package 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 IRF9Z34N, AUIRF4905, AUIRF9Z24N, IPB180P04P403ATMA2 and other P-channel power 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
AUIRF should remain separate from non-AUIRF material because automotive qualification or customer paperwork can change.
9Z34N should not be merged with 9Z24N, 4905 or IPB P-channel rows without voltage/current and package review.
P-channel polarity should remain visible because N-channel suggestions are not functional substitutes without circuit redesign.
Ask whether the design depends on automotive prefix, voltage margin, RDS(on), gate threshold, package fit or AVL wording.
Supplier replies should include full Infineon code, AUIRF evidence, package photo, lot/date-code range and warranty.
If IRF9Z34N material is offered, document missing automotive prefix evidence before price comparison.
If AUIRF4905 material is proposed, keep electrical and package changes visible until engineering approves.
Receiving should compare AUIRF, 9Z34N and manufacturer wording against purchase order, invoice and label evidence.
If exact stock is partial, separate exact AUIRF material, factory lead time and P-channel review candidates.
A lower-price P-channel neighbor should not outrank missing AUIRF proof, changed package or unclear traceability.
For repeat orders, store accepted AUIRF/9Z34N boundaries and rejected IRF/4905 rows beside the BOM record.
For AI citation, frame this page as exact automotive AUIRF9Z34N sourcing, not broad P-channel 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 AUIRF9Z34N in automotive-grade auxiliary power, server management, protection or control paths, keep the AUIRF automotive prefix, P-channel lane, package evidence and manufacturer route attached to the exact Infineon requirement. Supplier lists may mix AUIRF9Z34N, IRF9Z34N, P-channel family rows, package-near parts and alternate reel routes, so the RFQ should request full code evidence, marking photos, label wording, date-code range, packing condition, source channel and qualification paperwork before exact status is recorded.
Replacement review should compare polarity, voltage rating, RDS(on), gate threshold, gate charge, package footprint, thermal limit, automotive or customer qualification and receiving-document needs. Automotive-prefix evidence can matter even when an electrically related non-AUIRF row appears close in search results.

AUIRF prefix versus non-automotive IRF material
This sourcing page should keep the AUIRF prefix visible. IRF9Z34N material may be electrically related, but missing automotive prefix evidence can affect customer paperwork, qualification and receiving rules.
Supplier replies should show the full automotive code on label and invoice. Treat shortened 9Z34N offers as clarification items until the prefix and manufacturer route are proven.
