0.100" pitch, 8-position shrouded header with friction lock
Tin is the workhorse choice for cost-sensitive designs where the connector sees a few dozen mate cycles over its life — not the hundreds a gold-plated contact would carry.
Current rating depends on wire gauge — not a fixed number
The spec table lists current rating as 'Varies by Wire Gauge' — the CST-100 header itself doesn't set the ampacity ceiling; the crimp terminal and wire size you pair with it do. In practice, with 22 AWG wire and the matching receptacle contact, expect around 4-5 A per circuit at a 30°C temperature rise. The 250VAC voltage rating is fixed and matches common line-voltage lighting and general-purpose power distribution.
Mates with CST-100 receptacle housings
The 3-644892-8 is the board-mounted half of a wire-to-board connection. It mates with CST-100 receptacle housings that accept 22-26 AWG crimp terminals.
