FAQ
Frequently asked questions
Straight answers about how an independent distributor works.
Is NetSource Technology an authorized or franchised distributor?
No. NetSource is an independent electronic component distributor. We aren't franchised by manufacturers, which lets us stock and source across the open market when authorized channels are out of stock, on allocation or quoting long lead times.
How do you make sure the parts are genuine?
Every incoming lot undergoes a documented Level 1 inspection performed by our warehouse team. We maintain strong anti-counterfeit controls, provide available traceability documentation, and arrange third-party testing when you request it.
Can you find obsolete or end-of-life parts?
Yes. Discontinued and NRND parts are a large share of what we source. We check our own stock first, then search domestic and global suppliers.
How fast will I hear back on a quote?
We check our own stock first, then go out to domestic and global suppliers the same day, and in most cases report back with real availability within 24 hours.
What should I include in an RFQ?
The manufacturer part number, manufacturer, quantity and the date you need the parts. A target price helps if you have one. You can send a single part or a full BOM.
Do you buy excess inventory?
We help companies recover value from excess, end-of-life and surplus inventory through SmartExcess consignment. You keep ownership and approve each sale.
