Wire-to-Board Connectors from China
1 resources tagged with "Wire To Board"
Wire-to-board connectors like JST's PH (2.0mm pitch), XH (2.5mm), GH (1.25mm), and SH (1.0mm) series are among the most cloned parts coming out of China. Genuine JST holds tighter contact tolerances than the typical clone, and on small-pitch parts that gap shows up as intermittent contact or low retention force. The practical decision is whether your application can tolerate a clone or needs genuine JST sourced through an authorized channel.
When sourcing wire-to-board connectors, confirm the pitch and current rating match your wire gauge, and specify genuine vs compatible explicitly in the PO — clones are common and their crimp tolerances drift, which is a frequent cause of field connection failures.

FAQ
Are clone JST connectors a problem?
Sometimes. Clones can work for low-vibration, low-current designs but tend to have looser tolerances, weaker retention, and inconsistent crimp dimensions. For anything that ships to customers or sees vibration, specify genuine JST.
How do I match the connector to my wire?
Match the series pitch and the contact's rated wire gauge range. For example JST PH at 2.0mm pitch handles roughly AWG 32–24; using wire outside that range causes poor crimps.
