HT3.96mm HT5.08mm PCB Terminal Block — Pluggable Wire Connector for Power Boards
HT3.96mm & HT5.08mm Pluggable PCB Terminal Blocks — Compact Plug-In Connectors for Power Supply & Motor Boards
The HT3.96mm and HT5.08mm pluggable PCB terminal blocks are specialized plug-in connector systems used extensively in switching power supplies, motor driver boards, LED drivers, and compact industrial power electronics. The HT3.96mm pitch is particularly common in consumer and industrial power supply output terminals, while HT5.08mm is used for higher-current power connections. Both feature the two-part pluggable design: a PCB-soldered male header and a field-wireable female plug that inserts and removes without tools.

HT3.96mm vs HT5.08mm — Which to Choose?
HT3.96mm is the compact option, widely used in consumer power supplies and LED drivers where board space is limited. HT5.08mm provides greater creepage distance and is preferred for higher-voltage or higher-current power connections. Both are not interchangeable — verify your PCB footprint before ordering.
Frequently Asked Questions
Q: Are HT3.96mm terminal blocks the same as KF3.96mm?
A: HT and KF are trade names used by different manufacturers for the same 3.96mm pitch pluggable terminal block system. They are dimensionally interchangeable.
Q: What is the current rating for HT5.08mm?
A: HT5.08mm is typically rated 15–20A depending on the specific product variant. Verify the datasheet for your specific application.
