The cheapest part on the BOM delays the whole shipment
- Fragmented SKUs raise management costConnectors and passives are numerous and low-value — sourcing them supplier by supplier costs more in admin time than in parts.
- Housings and terminals must be bought togetherBuying housings without terminals, or terminals in the wrong pitch, is the most common mistake in this category.
- Factory pack sizes far exceed usageA reel of thousands when you need hundreds — the remainder becomes dead stock.
- One missing part blocks the orderDozens of line items complete except one terminal, and the whole shipment sits in the warehouse.
Commonly stocked and commonly sourced
| Sub-category | Common part number families | Sourcing note |
|---|---|---|
| Board-to-board | Hirose DF series · AXK series | Pitch and stacking height drive selection; compare tolerances for substitutes |
| Wire-to-board | JST XH / PH / SH series · Hirose DF11 series | Housings and terminals must ship as a set — buying separately causes shortages |
| FPC / FFC | Hirose FH series · JST FFC series | Confirm pitch (0.5 / 1.0mm) and flip-lock type |
| MLCC | 0402 / 0603 / 0805 common capacitance values | Automotive and high-voltage grades need separate certification checks |
| Electrolytic capacitors | Panasonic FR / FM series · common aluminium electrolytics | Lifetime and temperature rating determine substitution feasibility |
| Crystals & resonators | Seiko · Micro Crystal · Fenghua | Frequency tolerance and load capacitance must be checked item by item |
Connectors require confirmation of pitch, pin count, stacking height and plating — send the full part number for an accurate quote.
Frequently asked questions
Can you kit a full BOM?
Yes. Send the complete BOM including connectors and passives; we kit the whole order and ship it as one lot, flagging shortage items in advance and shipping the complete subset first.
Is there a minimum order?
No order-level minimum. Where a single part falls below factory packaging, we break packs and label the batch and break information.
Can I specify the brand?
Yes — Hirose, JST, Panasonic and others on request, or a domestic equivalent on the same spec, with a price and lead-time comparison for both.
