345-050-523-503

Edgeboard Connectors Overview

The EDAC Inc. 345-050-523-503 is a standard card edge connector socket from the 345 series, featuring 50 positions in a dual-row configuration. It utilizes a 0.100-inch (2.54mm) pitch and accepts board thicknesses ranging from 0.054 to 0.070 inches. The contacts are constructed from copper alloy with gold plating and employ a cantilever spring design for reliable engagement. This component supports through-hole termination via PC pins and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual female contact configuration designed for non-specified double-sided card edge boards
• Cantilever spring contact mechanism ensures secure mating force and electrical continuity
• Gold-plated copper alloy contacts provide corrosion resistance and low contact impedance
• Thermoplastic polyester insulation housing offers thermal stability and mechanical durability

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Medical device circuit board assemblies
• Automotive electronic module connections

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required termination style and flange configuration. Confirm compliance with RoHS3 and REACH regulations as applicable to your region. Ensure the selected variant aligns with the intended PCB thickness and mounting orientation requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 50-position interface is required for vertical through-hole mounting. The 2.54mm pitch accommodates standard board layouts. Consider the gold plating thickness and current rating if high-reliability or harsh environment performance is necessary compared to tin-plated alternatives.

Edgeboard Connectors Part Context

This part belongs to the EDAC 345 series of standard card edge connectors. The series provides various position counts and row configurations to support diverse interconnect needs. The 345-050-523-503 specifically addresses applications requiring robust dual-sided connectivity with standardized spacing and durable materials.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include EDAC 345-050-523-504 and 345-050-523-807. Verify that alternative part numbers match the exact pin count, pitch, and termination method to ensure mechanical and electrical compatibility without redesigning the host PCB.
