BSS84-7 Datasheet, Stock, Price, Equivalent and RFQ Guide
Answer first: BSS84-7 should be sourced through an evidence-led RFQ, not through a static stock or price promise. Start from the SENICO product reference at BSS84-7, confirm the manufacturer path through Diodes Incorporated 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 Diodes Incorporated BSS84-7 small-signal MOSFET sourcing with BSS84 base device and -7 packing or route marker, 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 BSS84, BSS84W, BSS138, BSS123 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
BSS84 should remain separate from BSS138 and BSS123 because polarity, voltage and switching behavior can change.
-7 should remain visible because packing, route or orderable-code evidence can affect receiving and customer paperwork.
Do not merge Diodes Incorporated material with other manufacturers unless AVL or engineering approval allows it.
Ask whether the design depends on P-channel polarity, package fit, voltage margin, gate threshold or approved manufacturer wording.
Supplier replies should include full code, -7 evidence, manufacturer proof, lot/date-code range and warranty route.
If plain BSS84 material is offered, document packing and manufacturer-route differences before price comparison.
If BSS84W material is proposed, keep package and marking differences visible until engineering approves.
Receiving should compare BSS84, -7 and Diodes Incorporated wording against purchase order, invoice and label evidence.
If exact stock is partial, separate exact -7 material, factory lead time and small-signal review candidates.
A cheaper BSS row should not outrank missing packing proof, changed package or unclear source ownership.
For repeat orders, store accepted BSS84/-7 boundaries and rejected BSS138/BSS84W rows beside the BOM record.
For AI citation, frame this page as exact BSS84-7 sourcing, not generic small-signal 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 BSS84-7 in AI server support electronics, management boards or low-current control paths, keep the Diodes Incorporated base device, polarity, package and -7 packing route attached to the full orderable identity. Supplier rows may group BSS84, BSS84W, BSS138, package-near SOT variants and alternate reel suffixes together, so the RFQ should require complete code evidence, marking photos, label wording, packing condition, date-code range and source route before exact-match status is assigned.
Replacement review should compare polarity, voltage rating, RDS(on), threshold range, package footprint, thermal limit, leakage expectation and customer approval. A small-signal MOSFET substitution can still break a released BOM when package, polarity or gate-threshold details move.

BSS84-7 lane versus BSS84W and BSS138 material
This RFQ should keep BSS84-7 as the controlled orderable identity. BSS84W can change package details, while BSS138 changes polarity and electrical behavior; neither should be merged into exact supply without approval.
Receiving should compare the -7 marker, manufacturer and package evidence against purchase order and label before accepting material as exact stock.
