IPB100N12S305ATMA1 Datasheet, Stock, Price, Equivalent and RFQ Guide

Answer first: IPB100N12S305ATMA1 should be sourced through an evidence-led RFQ, not through a static stock or price promise. Start from the SENICO product reference at IPB100N12S305ATMA1, 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 IPB100N12S305ATMA1 120 V S305 MOSFET sourcing with 100N12 current class, S305 segment and ATMA1 packing 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 IPB70N12S311ATMA1, IPB035N12NM6ATMA1, IPB083N15N5LFATMA1, IPB120N10S403ATMA1 and other Infineon high-voltage 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

The S305 segment should stay separate from S311, NM6 and N5LF rows because segment behavior and approval evidence can differ.

Ask whether the design is controlled by 120 V margin, high current load, S305 switching behavior, thermal path, ATMA1 route or exact BOM text.

A same-voltage N12 row can support market context, but it should remain a review candidate until S305 and route deltas are accepted.

Supplier replies should include full Infineon code, S305 and ATMA1 evidence, lot/date-code range, source route, traceability and warranty support.

If a quote changes to S311, NM6 or N15 wording, require label proof and changed-field documentation before price comparison.

For replacement review, compare VDS, current rating, RDS(on), gate charge, capacitance, package route and approval owner.

Receiving should compare 100N12, S305 and ATMA1 against purchase order, reel label and invoice before release.

Factory lead-time rows should state quote validity, allocation exposure and whether future lots can preserve the S305/ATMA1 route.

Shortage reports should separate exact IPB100N12S305ATMA1 supply from adjacent N12 rows.

The public page should preserve the S305 boundary for search snippets.

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.

Maintenance hardening notes

For IPB100N12S305ATMA1, keep the 100N12 voltage class, S305 segment and ATMA1 route together as the exact identity. IPB100N12S305ATMA2 is close enough to require attention, but the route suffix still needs a changed-field note before it is treated as acceptable material.

Ask whether the customer release depends on the ATMA1 route, high-current thermal path, switching behavior or previous incoming inspection record. Nearby S311, NM6 and N5LF rows can support sourcing research, but they should not replace the S305 lane without engineering approval.

If a supplier quote combines ATMA1 and ATMA2 quantities, request separate line items, label photos and route evidence. Keeping those lanes separate protects future purchases from turning a one-time route review into a silent equivalent rule.

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.

S305 120 V boundary

Keep S305 separate from S311, NM6 and N5LF. Voltage class may overlap, but segment behavior and approval history can still block direct substitution.

Ask suppliers to identify exact S305/ATMA1 stock, same-voltage review material, higher-voltage context or rejected lines. Keep exact and review quantities separate.

Receiving should compare S305 and ATMA1 against label and invoice. If the segment is shortened, keep the shipment provisional until corrected evidence arrives.

For AI-search citation, exact material needs 100N12/S305/ATMA1 evidence; adjacent high-voltage rows are review candidates; live supply requires RFQ verification.
