COMPONENT SOURCING / IC
Integrated circuits
For an IC enquiry, a family name is only the beginning. The full manufacturer ordering code identifies the device variant you need to discuss, while your application requirements explain which differences can matter.
- Power management
- Microcontrollers
- Analog & interface
SOURCING CHECKLIST
Details to include with your RFQ
Keep the requirements on the same enquiry. Mark unknown details for confirmation.
- 01
Exact identification
Manufacturer, complete orderable part number and the approved BOM revision. Preserve every prefix, suffix, hyphen and packing code.
- 02
Package and assembly
Package drawing, pin count, footprint and required carrier format. Note any moisture handling or assembly constraints specified by your manufacturing team.
- 03
Operating requirements
Supply range, temperature grade and the parameters critical to your design. For memory and controllers, include capacity, interface and any approved revision requirements.
- 04
Quantity and timing
Required units, minimum acceptable quantity, split delivery options and the date material is needed at your delivery location.
- 05
Documentation
State the origin, traceability, date-code and inspection evidence your purchase requires. Ask what is available before accepting an offer.
ENGINEERING REVIEW
Keep the original requirement visible
A matching function or pin count does not establish a drop-in replacement. Package, pin assignment, electrical behaviour, firmware and qualification requirements need engineering review.
List a proposed alternative separately with its full code and approval status. Confirm the part, quantity, condition, documentation and delivery assumptions before purchasing.

Before you enquire
Can I enquire with only a marking from the package?
Yes, but mark the identification as unconfirmed. Include clear photographs, package dimensions and the original equipment context. A top marking may differ from the full ordering code.
Should reel and tray variants share a BOM line?
Keep the requested ordering code intact. If your assembly team accepts another carrier, list it separately with its full code and indicate the approval status.
