Description

Dual-row sockets with stamped contacts

IC397 and IC398 sockets provide through-hole connections using stamped copper-alloy contacts and tin plating. IC397 has 2.54mm pitch; IC398 uses 1.778mm pitch. Select both the total contact count and the row spacing for the target IC and PCB layout.

IC397 dimensions

The contact pitch is 2.54±0.1mm and terminal width is 0.60±0.05mm. Both section views show a 4.80mm housing dimension and 0.15±0.05mm terminal thickness. The straight form has a 3.0±0.3mm projecting terminal dimension; the kinked form has a 2.8mm projection and a 0.55mm reference offset.

A is body length, B is the distance between the end-contact centres, C is body width and D is row spacing. Table values are in millimetres.
