What are the key features of MEC8-113-02-L-D-RA1?
- Card edge socket design with 10 micro-inch gold over 50 micro-inch nickel mating contacts for durable, low-resistance card-to-board connections
- Dual-row configuration in a compact 0.654-inch body length enabling high-density signal routing on card edge interfaces
- RoHS-compliant (Pb-free) construction with tin-over-nickel barrier termination, supporting lead-free solder reflow assembly
What is MEC8-113-02-L-D-RA1 used for?
The MEC8-113-02-L-D-RA1 is engineered for card edge interconnect applications in embedded computing, industrial I/O modules, and communications expansion boards where a reliable PCB card-to-board interface is required. Its dual-row gold-over-nickel mating contacts maintain low contact resistance through hundreds of card insertion and removal cycles, making it suitable for field-replaceable module designs. The compact body dimensions and tin-over-nickel termination support automated SMT assembly in volume manufacturing environments.

Frequently Asked Questions
What contact finish specification does the MEC8-113-02-L-D-RA1 use, and why does the nickel underplate matter?
The MEC8-113-02-L-D-RA1 uses 10 micro-inches of gold over 50 micro-inches of nickel on its mating contacts. The nickel underplate acts as a diffusion barrier, preventing copper from migrating through the gold layer and forming copper oxide that would increase contact resistance over time. This dual-layer finish extends connector service life in high-cycle card edge applications significantly beyond connectors with gold-direct-on-copper plating.
For a field-replaceable I/O module design, how many insertion cycles can the MEC8-113-02-L-D-RA1 card edge socket reliably handle?
Card edge sockets with 10 micro-inch gold over 50 micro-inch nickel contacts, as used in the MEC8-113-02-L-D-RA1, are typically rated for at least 50 to 100 mating cycles under standard test conditions, with actual performance depending on card edge plating quality. For field-replaceable I/O modules requiring frequent swaps, this gold-over-nickel finish outperforms tin-plated alternatives and prevents the fretting corrosion that degrades signal integrity at the card edge interface.
What body dimensions should a PCB layout engineer account for when placing the MEC8-113-02-L-D-RA1 on a board?
PCB layout engineers placing the MEC8-113-02-L-D-RA1 should allow for a body length of 0.654 inches, body depth of 0.227 inches, and body breadth of 0.291 inches in the keep-out and placement zones. The tin-over-nickel termination contacts require standard SMT land patterns compatible with lead-free reflow soldering, and clearance should account for the card insertion direction perpendicular to the connector body length axis.
