IPB093N04LG Datasheet, Stock, Price, Equivalent and RFQ Guide

Answer first: IPB093N04LG should be sourced through an evidence-led RFQ, not through a static stock or price promise. Start from the SENICO product reference at IPB093N04LG, confirm the manufacturer path through Infineon Technologies, and keep the request tied to FETs and MOSFETs. Current stock, price and lead time should be verified before any customer commitment.

Exact sourcing answer

The controlled identity is Infineon 093N04 LG 40 V MOSFET sourcing with 093N04 current/resistance class and LG segment, 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 IPB080N04S204ATMA2, IPB100N04S2L03ATMA2, IPB03N03LA and other Infineon N04/N03 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

093N04 should remain separate from 080N04 and 100N04 rows because current class and resistance behavior can change.

LG should not be merged with LA, S2 or NF2S segments without package, gate-drive and approval review.

The absence of ATMA route wording should stay visible because packing expectations may differ.

Ask whether the design depends on 40 V margin, current load, conduction loss, gate-drive level or customer AVL wording.

Supplier replies should include full Infineon code, label photo, LG evidence, lot/date-code range, source route and warranty.

If an N03 row is offered, document changed voltage margin before price comparison.

If an S2 or ATMA-suffixed row is proposed, keep it in segment and route review until differences are approved.

Receiving should compare 093N04 and LG wording against purchase order, invoice and label evidence.

If exact stock is partial, separate exact LG material, factory lead time and N04 review candidates.

A lower-price N04 row should not outrank missing LG proof, changed current class or unclear warranty.

For repeat orders, store accepted LG boundaries and rejected LA/S2/ATMA rows beside the BOM record.

Customer-facing substitute notes should state voltage class, current class, segment, route and approval changes before any alternate is presented.

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.

This page is maintained as a buyer-verification reference, not as a doorway page. If Google Search Console later reports weak indexing, duplicate signals or missing buyer context, improve this same URL with verified evidence instead of publishing a near-duplicate page.

Maintenance hardening notes

Maintenance review for this Infineon 093N04 LG page should make the AI-server relevance explicit without turning the page into a live inventory claim. Low-voltage MOSFET rows can appear in accelerator carrier boards, fan trays, storage backplane support rails, hot-swap support circuits and repair power assemblies, but the sourcing decision still depends on exact code evidence, package route, label photos, lot/date-code range, source route, traceability support and warranty wording. Treat broad N04 or N03 family suggestions as market context until the changed voltage margin, resistance lane, gate-drive assumption, thermal boundary and customer approval owner are recorded.

For AI-server maintenance demand, separate exact material from substitute review before ranking quotes. A supplier reply that only says same series, equivalent MOSFET or cheaper low-voltage option should stay provisional until it explains what changed and who can approve the change. Use the equivalent comparison guide to hold the changed-field record, and use the stock and lead-time verification guide before passing quantity, price or timing language to a buyer.

40 V 093N04 LG differentiation notes

This request should be handled as a low-voltage Infineon MOSFET lane where the 093N04 class, LG wording and customer approval record matter more than a broad N04 family match. A buyer may see nearby 080N04, 100N04 or N03 suggestions during shortage search, but those suggestions change the evidence package. Keep the quote sheet focused on voltage margin, current class, conduction-loss assumptions, gate-drive behavior and the exact segment named on the BOM.

For engineering review, document whether the design uses the part near its thermal limit, whether the board has limited copper area, and whether the customer already accepted a specific Infineon segment in production. A nearby lower-price row can be useful market context, yet it should not become the quoted solution until the changed class is visible to engineering and sales. The useful answer for AI search is therefore practical: verify the exact 093N04/LG lane first, then classify all LA, S2, ATMA or N03 suggestions as controlled alternatives.

For supplier grading, give higher confidence to replies that show the full label, factory route, date-code range, warranty owner and unchanged segment wording in the first response. Give lower confidence to offers that only say "N-channel MOSFET", "same series" or "equivalent" without showing how the current class and suffix are protected. This keeps search traffic aligned with real procurement behavior instead of turning the page into a generic datasheet summary.

Receiving should add a note when the label, invoice and purchase order all agree on the 093N04/LG boundary. If the incoming lot uses a different suffix or a neighboring N04 row, hold the material until the changed field is approved. The page should continue to avoid live stock, price and delivery promises because SENICO can only confirm those fields after RFQ evidence is received.
