Component Sourcing & Turnkey PCBA FAQ

Are the components new and original?

Yes. OrinewPCB supplies only 100% new, original, genuine electronic components. We do not supply used, refurbished or remarked material. This commitment also covers the components we supply for customers’ turnkey PCB assembly builds.

Can you source a part that is not in your own stock?

Yes. We work with component manufacturers and distribution partners to review sourcing options beyond our substantial inventory. Send the exact part number and quantity so pricing, availability and delivery can be confirmed for your request.

Does a listed quantity confirm immediate delivery?

Confirm the current available quantity, packaging, any date/lot requirements and delivery date in your quotation. Directory counts and listed quantities do not reserve material or confirm that every listed item is currently in our own warehouse.

Can I request a full BOM and finished PCB assemblies?

Yes. Send the BOM together with matching PCB design files and build quantity. State whether you need components only, partial turnkey or full turnkey PCB assembly, and identify programming and testing requirements.

Will you change a part number without our approval?

No. Proposed substitutes must be reviewed and approved by your team before they replace the released BOM. Tell us which lines cannot be substituted and which approved alternatives may be quoted.
