Jason Cheng · one accountable contact. You speak with the same person from RFQ review through China-side order follow-up.
Independent sourcing service. MPNBridge is not a franchised distributor or inventory marketplace; supplier stock is never presented as our own.
Two focused services
Start with the request you already have.
The website does not ask you to browse a catalogue. It helps us establish the exact requirement before anyone treats a search result as a quotation.
02 · LOW-VOLUME BOM
Lines split across suppliers
We clean each line, track its status, coordinate approved purchases and bring them to one Shenzhen receiving point before consolidation.
Review the Low-Volume BOM workflow →Use us where coordination matters
A useful sourcing contact—not an extra layer on every order.
Good fit
- A complete MPN needs a China-side source comparison.
- A low-volume BOM is fragmented across several suppliers.
- You want source limitations stated before approval.
- You need one receiving and consolidation point in Shenzhen.
- You can provide a real company identity, destination and intended use.
Probably not needed
- A common active part is already available from an authorized distributor you can use directly.
- You only want a lowest-price screenshot without comparable source and trade terms.
- You need supplier stock represented as MPNBridge inventory.
- You need a substitution made without your engineering approval.
- The buyer, payer, consignee, destination or end use cannot be explained.
A four-step handoff
What happens after you send an RFQ.
Clarify
Review the full MPN and quantity, then ask only for the missing trade and screening details.
Source
Establish an authorized-channel baseline where available, then consider approved alternatives case by case.
Compare
Keep price, source type, packing, lead time, documents and remaining uncertainty visible.
Coordinate
Purchase only after approval, receive in Shenzhen, perform the agreed checks, record exceptions and consolidate.
Illustrative output
A comparison that keeps unlike sources unlike.
This format is an example only. It is not inventory, a quotation or an offer.
| Full MPN | Quantity | Source type | Packing / date code | Documents | Availability | Limit / next step |
|---|---|---|---|---|---|---|
| DEMO-MPN-001 | 500 | Authorized baseline | Reel / confirm | Per quoted source | Reconfirm before order | Compare landed terms |
| DEMO-MPN-002 | 200 | Independent, disclosed | Tray / limited data | Not yet established | Supplier claim only | Enhanced review or no quote |
One owner · visible follow-through
What stays visible after you approve an order.
LEAD TIME
Track the stated date.
Quoted dates are tracked; known supplier changes are communicated promptly.
RECEIVING CHECKS
Record what was checked.
Agreed visible checks are photographed. They do not replace authenticity or electrical testing.
EXCEPTIONS
Escalate before handoff.
Known shortages, wrong parts and visible discrepancies are separated and documented before onward shipment.
HANDOFF
Keep the record together.
Approved goods are consolidated with the agreed tracking, documents and exception record.
We do not promise margin, perfect quality or a delay-free supply chain. The commitment is a named owner, a documented process and no known substitution or scope change without your approval.

Common questions
Know what the service is before you inquire.
Are you an authorized distributor?
No. MPNBridge is an independent sourcing service. A quotation may include a documented authorized source for a specific line, but that does not make MPNBridge a franchised distributor.
Do you hold stock?
No. We source on demand. Availability and price are supplier information that must be reconfirmed before an order.
Why not buy directly from DigiKey or Mouser?
You should buy directly from an authorized distributor when it has the required part, quantity and terms. MPNBridge is useful when a line needs China-side source comparison, a low-volume BOM is fragmented across suppliers, or you need one Shenzhen receiving and consolidation point.
Can you guarantee that a component is authentic?
No blanket authenticity claim is made. The quotation and order record should state the source, available evidence, agreed checks and unresolved risk.
What checks do you perform?
Current receiving checks cover quantity, labels, full MPN, manufacturer marking, package form, date and lot codes, obvious visible anomalies and a photographic record. They do not prove internal die authenticity, full electrical performance or solderability.
Can I upload a confidential BOM?
The full RFQ form accepts one XLSX, XLS, CSV or PDF BOM up to 10 MiB and forwards it to our verified business mailbox. Send only the information needed for initial review; for especially sensitive material, contact us first to agree a transfer method and confidentiality terms.
What makes an RFQ quote-ready?
Upload a supported BOM, or start with the complete MPN and quantity. A work email is always required. We can confirm destination, required date, source preference, intended use, packing and date-code requirements in the follow-up.
Start with the essentials
Start with one complete MPN.
A small first order is welcome when the scope is suitable. Send the part number, quantity and work email; we will collect the remaining details in follow-up.
