2N7002 Datasheet, Stock, Price, Equivalent and RFQ Guide

Answer first: 2N7002 should be sourced through an evidence-led RFQ, not through a static stock or price promise. Start from the SENICO product reference at 2N7002, confirm the manufacturer path through Diodes Incorporated, 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 Diodes Incorporated small-signal N-channel MOSFET sourcing with base code, N-channel lane and maker/package evidence, 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 BSS138, K-suffix variants, DW dual-channel variants, BSS84TA and other small-signal MOSFET 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

2N7002 should remain separate from BSS138 because package, pinout, gate threshold and approval history can change.

Do not treat dual-channel or suffix variants as exact material without package and marking review.

Manufacturer evidence matters because generic small-signal market supply can mix makers, packages and date-code rules.

Ask whether the design uses logic-level switching, signal translation, load isolation, repair stock or customer AVL wording.

Supplier replies should include full maker code, package/marking photo, lot/date-code range, packing state, source route and warranty.

If a K-suffix or DW dual-channel line is offered, document suffix, package and channel-count changes before price comparison.

If BSS138 is proposed, keep it in electrical and package review until differences are approved.

Receiving should compare base code, package, maker and marking against purchase order, invoice and label evidence.

If exact stock is partial, separate exact Diodes material, factory lead time and generic review candidates.

A lower-price small-signal MOSFET should not outrank missing maker proof, changed package or unclear warranty.

For repeat orders, store accepted maker/package boundaries and rejected generic or dual-channel rows beside the BOM record.

Customer-facing substitute notes should state maker, package, channel count, 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.

Maintenance hardening notes

For 2N7002, treat manufacturer, package code and packing route as controlled RFQ fields because the base small-signal MOSFET number is widely multi-sourced. Supplier rows may combine Diodes Incorporated material with other makers, SOT-23 package-near options, reel or cut-tape variants and date-code ranges, so the RFQ should request the complete manufacturer code, package and marking evidence, label wording, packing state, traceability documents and source route before assigning exact-match status.

Equivalent review should compare polarity, voltage rating, RDS(on), gate-threshold range, capacitance or switching behavior, package footprint, qualification status and customer AVL rules. Generic base-number matches can help discovery, but production approval depends on maker, package and documented acceptance criteria.

Keep maker-specific approvals separate from open alternate leads.
