Product details

Pitch, Positions, and Current Ceiling

The 77313-818-36LF: The 3 A per-contact rating holds at the listed operating temperature range; above 85 °C ambient, derate per the product drawing. The 0.230" (5.84 mm) mating pin length mates with standard 2.54 mm pitch female socket strips — the same pitch used across the BERGSTIK and compatible IDC families. Pin-one is marked by the chamfered edge of the black thermoplastic housing.

Mating Finish and Cycle Life

At this plating grade, expect 50–100 mating cycles before contact resistance begins to rise — fine for bench-test or field-service connectors that see occasional disconnect, not daily hot-plug. No gold on the post; the tin surface is compatible with both leaded and lead-free solder processes.

The part is RoHS compliant and carries UL94 V-0 flammability rating on the thermoplastic housing.

Frequently asked questions

Is 77313-818-36LF compatible with standard 2.54 mm female headers?

Yes. Confirm the mating half has 36 positions in a dual-row layout.

Does this header have a locking feature?

No. The fastening type is push-pull, and the connector is unshrouded — there is no latch, ramp, or secondary lock. Mating retention relies on the friction fit of the pins in the socket. For vibration-prone applications, add a wire tie or use a shrouded header with a locking ramp.
