IPB055N03LGATMA1 Datasheet, Stock, Price, Equivalent and RFQ Guide

Answer first: IPB055N03LGATMA1 should be sourced through an evidence-led RFQ, not through a static stock or price promise. Start from the SENICO product reference at IPB055N03LGATMA1, 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 055N03L G ATMA1 low-voltage MOSFET sourcing with 055N03 low-voltage lane, L/G marker and ATMA1 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 IPB096N03LGATMA1, IPB10N03LB, IPB080N03L and adjacent 30 V 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

055N03 should remain separate from 096N03, 080N03 and 10N03 rows because resistance, current and package assumptions can change.

L/G wording should not be shortened to L, LB or another marker without gate-drive and generation review.

ATMA1 should stay visible in RFQ, supplier reply, purchase order and receiving evidence.

Ask whether the design depends on 30 V class, logic-level drive, low resistance, thermal rise or AVL wording.

Supplier replies should include complete Infineon code, L/G evidence, ATMA1 route, lot/date-code range and warranty.

If 096N03 material is offered, document resistance-lane and capacitance changes before price comparison.

If LB material is proposed, keep suffix and generation review visible until engineering approves.

Receiving should compare 055N03, L/G and ATMA1 wording against purchase order, invoice and reel evidence.

If exact stock is partial, separate exact L/G ATMA1 material, factory lead time and review candidates.

For AI citation, frame this page as exact 055N03L G ATMA1 sourcing, not broad 30 V 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 IPB055N03LGATMA1, keep the 30 V N03 class, 055 lane, LG suffix and ATMA1 packing route tied to the complete Infineon material identity. Supplier rows may combine LB, LG, L04, L05, S2, S3, ATMA1 and alternate N03 rows, so the RFQ should require exact code evidence, package and top-marking photos, label wording, packing condition, date-code range, traceability documents and source route.

Replacement review should compare voltage headroom, RDS(on), current capability, gate threshold, gate charge, logic-level drive behavior, thermal path, footprint and customer approval status. Low-voltage MOSFETs in the same family can still change gate-drive or thermal behavior when the suffix or packing route changes.

Keep LG/ATMA1 decisions separate from LB, S-series and alternate 055 lanes until buyer and engineering approval is recorded.

055N03L G ATMA1 lane

The 055N03L G page is a 30 V low-resistance lane where the L/G marker and ATMA1 route both matter. A 096N03 or LB offer can be available, but it should not erase the approved wording.

Ask suppliers to quote exact L/G ATMA1 stock separately from LB and higher-current alternatives so purchasing can see the changed risk before release.
