Product details

Board Layout Fit for the 24-Position Right-Angle Header

The 77317-104-24LF: The unshrouded design means the mating receptacle slides directly over the pins without a guide frame — alignment relies on the board layout and the mating half's keying, so verify the receptacle's polarization before committing the footprint.

Current and Contact Duty for Signal and Low-Power Lines

In a 24-position harness carrying mixed power and signals, the total current per pin stays below 3 A to keep the temperature rise within the thermoplastic housing limit. Operating temperature range from -65°C to 130°C covers automotive underhood and industrial cabinet environments — the wide span means the connector can sit in a cold warehouse or a hot enclosure without derating the current.

The 77317 base number covers the BERGSTIK series; the 104-24LF suffix specifies the 24-position, right-angle, gold-plated variant.

Frequently asked questions

What is the closest pin-compatible alternative to 77317-104-24LF?

The BERGSTIK series includes many 0.100" pitch headers, but a pin-compatible drop-in would need the same 24-position, dual-row, right-angle, unshrouded, gold-plated configuration — confirm the mating half and board pattern before substituting.

What is the pitch of 77317-104-24LF?

The mating pitch is 0.100" (2.54 mm), with the same row spacing. This is the standard 0.100" grid for BergStik headers.
