BSS84W-7 Datasheet, Stock, Price, Equivalent and RFQ Guide
Answer first: BSS84W-7 should be sourced through an evidence-led RFQ, not through a static stock or price promise. Start from the SENICO product reference at BSS84W-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 BSS84W-7 small-signal MOSFET sourcing with BSS84W package lane 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 BSS84-7, BSS84, 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
BSS84W should remain separate from BSS84 and BSS138 because package, polarity and electrical 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, W package lane, voltage margin, gate threshold or manufacturer wording.
Supplier replies should include full code, -7 evidence, manufacturer proof, lot/date-code range and warranty route.
If BSS84-7 material is offered, document package differences before price comparison.
If BSS138 material is proposed, keep polarity and electrical changes visible until engineering approves.
Receiving should compare BSS84W, -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 package proof, changed polarity or unclear source ownership.
For repeat orders, store accepted BSS84W/-7 boundaries and rejected BSS84/BSS138 rows beside the BOM record.
For AI citation, frame this page as exact BSS84W-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 BSS84W-7, keep the W-7 suffix, small-signal MOSFET package evidence and supplier packing route in one exact-material record. Supplier exports may group BSS84, BSS84W, BSS84P, reel-suffix rows and package-near alternatives together, so the RFQ should request full code evidence, package and marking photos, label wording, packing state, date-code range, traceability documents and source route before the offer is ranked as exact.
Alternate screening should compare polarity, voltage rating, RDS(on), gate threshold, package footprint, thermal limits, reel or tape route and customer approval status. Small-signal MOSFET substitutions can look harmless in search results, but suffix and package evidence can change production acceptance.
Carry every W-7 suffix, package or reel exception into the RFQ worksheet with the approval owner.

BSS84W-7 lane versus BSS84-7 material
This RFQ should keep the W package lane visible. BSS84-7 may share the BSS84 family, but the package marker changes and should be treated as a review item unless the customer approves it.
Receiving should verify BSS84W, -7, manufacturer and package evidence on label and invoice before accepting material as exact stock.
