Key Features
- Gold-over-nickel contact finish on mating surfaces providing low contact resistance and extended durability in high-cycle telecom interconnects
- Right-angle (RA) orientation enabling horizontal board-edge signal entry to reduce PCB vertical profile
- PEG board mounting option improving mechanical retention force and vibration resistance on populated PCBs
Applications
The ERI8-031-S-D-RA is used in telecom line cards, datacom switching equipment, and industrial networking modules where right-angle receptacle connectors with dual-row mating are required at a board-edge interface. Its gold-over-nickel contact finish supports reliable signal connections in environments with humidity and thermal cycling. The PEG mounting peg secures the connector body to the PCB, preventing movement during mating and unmating operations.

Frequently Asked Questions
What contact finish does the ERI8-031-S-D-RA use, and how does it benefit connector performance?
The ERI8-031-S-D-RA uses gold-over-nickel contact finish on the mating interface, which provides contact resistance below 20 milliohms, corrosion resistance in humid environments, and suitability for a minimum of 100 mating cycles in telecom and datacom applications.
Why would a PCB designer choose the right-angle (RA) orientation of the ERI8-031-S-D-RA over a vertical mounting variant?
The right-angle configuration routes signals horizontally from the board edge rather than vertically, reducing the assembled height above the PCB to less than 0.5 inch in many enclosures. This is particularly useful in 1U rack-mount telecom chassis where internal clearance between PCBs is less than 20 mm.
What does the PEG board mounting option in the ERI8-031-S-D-RA provide during assembly and field use?
The PEG mounting peg inserts into a PCB hole and acts as a mechanical anchor, increasing the force required to dislodge the connector body from approximately 5 N to over 20 N, ensuring the receptacle remains secure during repeated mating cycles and in vibration-prone installations.
What body dimensions should a PCB layout engineer account for when placing the ERI8-031-S-D-RA?
The ERI8-031-S-D-RA body measures 1.13 inches in length, 0.228 inches in breadth, and 0.448 inches in depth, requiring a keep-out zone of at least 30 mm by 12 mm on the PCB surface to accommodate the connector body and the right-angle mating clearance path.
