How to Choose the Right 3.96mm Wire-to-Board Connector
- Confirm the pitch – 3.96mm must match your PCB hole spacing and mating header.
- Select pin count – count the signals you need; leave spare pins if future expansion is likely.
- Choose mounting type – SMT (reflow, high density) vs DIP/THT (through-hole, stronger hold).
- Orient the header – straight (vertical) or right-angle, depending on enclosure height.
- Check current rating – 7.0A per contact typical; derate ~20% for continuous loads.
- Locking & polarization – choose a latching type if vibration or blind mating is expected.
- Plating – tin for general use, gold for low-signal or high-mating-cycle applications.
Typical Applications
3.96mm wire-to-board connectors are widely used in industrial control boards, consumer electronics, smart home
devices, LED lighting drivers, battery packs, sensor modules and medical instruments.
Frequently Asked Questions
What is the current rating of a 3.96mm wire-to-board connector?
Typically 7.0A per contact at ambient temperature. For continuous loads above 50°C, derate by about 20%.
Is this connector JST compatible?
Yes. RXSY 3.96mm series are designed as pin-to-pin replacements for the corresponding JST series (PH, XH, SH, GH, ZH, VH, CH), so they drop into the same PCB footprint.
What wire gauge does it support?
AWG #20–#16 depending on the contact design. Contact us with your wire specification for confirmation.
Do you provide samples and small-batch orders?
Yes. Samples ship within 7 days and small-batch production is supported with flexible MOQ.
Can you customize pitch, plating or housing color?
Yes. OEM/ODM customization is available including pitch, pin count, plating, housing color and packaging.
