Box Header vs Ejector Header: Selection Guide

A box header is a shrouded PCB header used with IDC sockets and ribbon cable assemblies. An ejector header adds latch or ejector structures to help secure and release the mating IDC connector in applications that need stronger retention or easier service.

Comparison table

Item	Box Header	Ejector Header
Main structure	Shrouded header with keyed housing	Shrouded IDC header with latch/ejector arms
Typical mating part	IDC socket or ribbon cable assembly	IDC socket requiring latch retention
Use case	General IDC ribbon cable connection	Industrial control, serviceable modules and secure cable connections
RFQ details	Pitch, positions, key direction, mounting style	Pitch, positions, latch direction, cable exit and mating socket

Selection notes

Select a standard box header when the application needs keyed orientation and normal IDC cable mating. Select an ejector header when the cable must be secured with latch arms, frequently removed, or protected from accidental loosening during equipment operation.

Common pitch options

Kirision reviews 1.27mm, 2.00mm and 2.54mm box header and ejector header structures. Mounting options can include vertical DIP, right-angle through-hole and SMT depending on the series and drawing.
