Product details

Board-Edge Cable Exit with Locking Ramp

Molex 205971-0083 is an 8-circuit, single-row header from the Micro-One 205971 series, pitched at 2.00mm.

SMT Solder Retention and Board-Level Reliability

This reduces the risk of lifted pads when the cable is tugged or during thermal cycling — a practical concern for connectors mounted near the board edge where strain is highest.

The tin-bismuth finish here is well-suited for one-time or infrequent mating in clean, dry environments.

If you need a drop-in alternative, the same Micro-One 205971 series offers other circuit counts and plating options; confirm the mating half and board footprint before substituting.

Frequently asked questions

What is the pitch and circuit count of 205971-0083?

The pitch is 2.00mm (0.079") and it has 8 circuits in a single row. All positions are loaded.

Is there a replacement or equivalent for 205971-0083?

The part is active, so no end-of-life cross-reference exists. If you need a different circuit count or plating, the Micro-One 205971 series offers other variants — verify the board footprint and mating half before switching.
