The hidden cost of a long BOM
Most schedule slips are not caused by the expensive parts — they come from one or two cheap, single-source line items that go on allocation. Consolidating MCU and power-management lines with one distributor removes a lot of that line-item chasing.
What a consolidated source does for you
- One RFQ covers many lines. Upload the BOM once and get one consolidated quote instead of twenty emails.
- Alternates offered up front. When a line is unavailable we propose an in-stock equivalent from the MCU or power range.
- Traceable date codes. Every line is quoted with visible date code and stock quantity.
- Small-quantity sampling. MOQ is 1 piece, so prototypes and production can share a source.
Lines we clear most often
| Part we stock | Line | Why it blocks builds |
|---|---|---|
| stm32f103c8t6 | MCU | Allocation cycles on the F1 family |
| gd32f103c8t6 | MCU | In-stock alternative for STM32F103 |
| lm2596s-5-0 | Power | Classic 3 A buck, high turnover |
| ams1117-3-3 | Power | Most counterfeited LDO line |
| cos6505b | Power | Isolated-supply driver, TI SN6505 gap |
A 60-second BOM checklist
Before you send a BOM, make sure it states: exact part number and package, target quantity, acceptable alternates, date-code requirement and any qualification constraint (industrial, automotive). That single line about alternates is what lets us substitute on the fly instead of coming back with questions.

Frequently asked questions
Do you charge for a BOM quote?
No. Submit the file and we will return availability, date code and pricing at no cost.
Can you handle a mixed BOM of MCUs, power ICs and passives?
Yes — MCU and power-management lines are our core, and we source the surrounding passives and connectors as well.
What format should the BOM be in?
CSV, XLSX or a plain list is fine; the key fields are part number, package and quantity.
