G3F18MT12K SiC/GaN Datasheet, Stock, Price and RFQ Guide

Answer first: G3F18MT12K should be sourced through an evidence-led RFQ, not through a static stock or price promise. Start from the SENICO product reference at G3F18MT12K, confirm the manufacturer path through GeneSiC Semiconductor, and keep the request tied to SENICO product categories. Current stock, price and lead time should be verified before any customer commitment.

Exact sourcing answer

The controlled identity is GeneSiC silicon-carbide power module sourcing for the G3F18MT12K lane with G3F family, 18MT12K power-module identity and exact ordering 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 G3F18MT12, G3F30MT12K, G3F45MT12K and other GeneSiC SiC power-module 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 18MT12K identity should remain separate from 30MT or 45MT rows because current class and thermal behavior can change.

K suffix evidence should stay visible from RFQ through receiving instead of being shortened to a broad G3F18MT12 offer.

Ask whether the design is limited by blocking voltage, current rating, module footprint, baseplate, thermal impedance or gate-drive behavior.

Supplier replies should include full GeneSiC code, package or module photo, label photo, lot/date code, source ownership and warranty.

If another G3F module is proposed, list changed current class, package and thermal fields before price comparison.

Receiving should compare module identity, label evidence and datasheet revision against the purchase order.

If exact supply is partial, split exact module stock, factory lead time and engineering-review SiC alternatives.

A broad SiC module offer should not outrank missing K suffix proof or unclear manufacturer route.

For high-power builds, ask whether switching loss, creepage, clearance, heat sink interface or gate-drive margin controls acceptance.

If supplier evidence only shows the G3F18 base, request corrected full-code proof before quoting exact stock.

For repeat demand, attach accepted module, thermal and label evidence to the sourcing record.

Customer-facing substitute notes should state current class, module route, thermal 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.

Maintenance hardening notes

G3F18MT12K should be handled as an exact GeneSiC SiC power-module request, not a broad G3F module inquiry. G3F18MT12, G3F30MT12K and G3F45MT12K suggestions can change current class, module construction, thermal behavior and the approval path for a high-power assembly.

Before forwarding a supplier response, collect full-code evidence, module photos, label photos, datasheet revision, lot/date-code range, source ownership and warranty terms. If the evidence only confirms the G3F18 base, hold the quote until the K suffix and module identity are clear.

For high-power builds, record whether blocking voltage, current rating, gate-drive behavior, creepage, clearance, heat-sink interface or thermal impedance controls acceptance. That engineering context lets the page remain useful without suggesting an automatic substitute or verified commercial supply.

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.
