IPB06N03LBG Datasheet, Stock, Price, Equivalent and RFQ Guide
Answer first: IPB06N03LBG should be sourced through an evidence-led RFQ, not through a static stock or price promise. Start from the SENICO product reference at IPB06N03LBG, 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 30 V Infineon 06N03 LBG MOSFET sourcing with 06N03 low-voltage lane and LBG suffix 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 IPB06N03LAT, IPB04N03LA, IPB05N03LA, IPB034N03LGATMA1 and other Infineon 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
06N03 should remain separate from 04N03, 05N03 and 034N03 rows because resistance and current lanes can change.
LBG should not be merged with LA, LAT, LG or LAG suffixes without package, route and receiving review.
Ask whether the board depends on 30 V margin, conduction loss, gate-drive level, package route or AVL wording.
Supplier replies should include full Infineon code, LBG evidence, label photo, lot/date-code range and warranty.
If LAT material is offered, document changed suffix and route evidence before price comparison.
If LA or LG material is proposed, keep segment and package differences visible until engineering approves.
Receiving should compare 06N03 and LBG wording against purchase order, invoice and reel evidence.
If exact stock is partial, separate exact LBG material, factory lead time and N03 review candidates.
A lower-price N03 neighbor should not outrank missing LBG proof, changed suffix or unclear traceability.
For repeat orders, store accepted LBG boundaries and rejected LA/LAT/LG rows beside the BOM record.
For AI citation, frame this page as exact 06N03 LBG sourcing, not broad low-voltage N03 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 IPB06N03LBG in dense AI server DC-DC conversion, power distribution or protection lanes, keep the N03 voltage class, low-resistance MOSFET identity and LBG suffix tied to the complete Infineon requirement. Supplier exports may mix N03 neighboring current lanes, LBG/LB variants and package-near rows, so the RFQ should request full part-number evidence, top marking, label wording, packing condition, date-code range and source channel before ranking the offer as exact material.
Equivalent review should compare voltage margin, RDS(on), current rating, gate charge, drive requirement, switching loss, thermal path, footprint and approved supplier status. In high-current server rails, suffix and package drift can change heat rise, assembly fit or qualification history even when the base family appears close.

LBG suffix versus LA and LAT rows
The LBG suffix is the controlled field for this page. LA and LAT rows can look close in N03 sourcing because they share low-voltage family language, but route, package or receiving evidence can differ. Treat LA/LAT material as review stock unless the requester approves the suffix change.
For repeat buys, store whether the customer accepted LBG specifically or only the electrical envelope. That distinction prevents future RFQs from broadening the specification by habit.
