What is the JST connector series and how do I select the right pitch?

JST (Japan Solderless Terminal) is one of the world's most widely used wire-to-board connector brands, with multiple families distinguished primarily by pitch (centre-to-centre pin spacing): JST PH (2.0mm pitch) — commonly used for battery connections in RC vehicles and IoT devices; JST ZH (1.5mm pitch) — compact, used in portable electronics; JST GH (1.25mm pitch) — used in FPV drones and miniaturised electronics; JST SH (1.0mm pitch) — ultra-compact, used in ultra-thin wearables; JST XH (2.5mm pitch) — standard hobby/RC connector; JST VH (3.96mm pitch) — higher current capacity, used in small appliances. When selecting connectors, always match pitch, pin count, housing lock style, and contact current rating to your application. Chinese JST-compatible connectors are widely available and cost-effective for non-critical applications, but certified OEM JST connectors should be used for applications requiring JST's full performance specifications.

What is the typical MOQ for wholesale electronic connectors from China?

Standard commodity connectors (2.54mm pitch headers, JST-compatible series, USB, HDMI) from Chinese manufacturers: MOQs of 100–500 pieces per SKU (connector body or contact/terminal kit). Mixed connector orders are commonly accepted at a minimum order value of USD 300–1,000. For circular connectors (M12, M8): 50–200 pieces per variant. Automotive-grade sealed connectors: typically 100–500 sets. Custom moulded connector tooling requires NRE (non-recurring engineering) investment and minimum production quantities — tooling costs range from USD 3,000–20,000 depending on complexity, with minimum production runs of 5,000–50,000 pieces.

Electronic connector types and applications overview

Electronic connectors are categorised by their mating direction, form factor, and application environment: board-to-board connectors (BB connectors — mezzanine or stacking connectors for connecting two parallel PCBs, available in 0.4mm to 2.54mm pitch; used in mobile devices, networking equipment, and modular electronics); wire-to-board connectors (WTB connectors — crimp-terminal connectors such as JST PH/ZH/GH/SH, Molex Micro-Fit, TE MTA series, Dupont/pin header 2.54mm — the most widely used in general electronics for wiring harness termination); wire-to-wire connectors (two wire harnesses terminated to each other, commonly used in automotive and industrial wiring); circular connectors (M12, M8, M5, M23, MIL-DTL-38999, Amphenol Circular Plastic Connectors — used in industrial automation, robotics, and harsh-environment applications requiring robust mating with IP rating); automotive connectors (USCAR-2 specification connectors, 0.35mm to 2.8mm pitch, sealed and unsealed — designed for automotive temperature ranges -40°C to +125°C and automotive vibration/shock; major systems include Delphi/Aptiv, TE DEUTSCH, Yazaki, and Sumitomo); USB, HDMI, DisplayPort, and standard consumer connectors; and RF/coaxial connectors (SMA, N-type, BNC, SMP, MMCX — for RF signal transmission in antennas, test equipment, and telecommunications).
