346-036-521-258

Edgeboard Connectors Overview

The EDAC Inc. 346-036-521-258 is a standard card edge connector receptacle from the 346 series, designed for vertical through-hole mounting. It features 36 positions with a 3.175 mm pitch and accommodates a board thickness of 1.57 mm. The contacts are made of copper alloy with gold plating, rated for 3 A current. The housing utilizes thermoplastic polyester insulation, ensuring an insulation resistance of 5 Gohms.

Edgeboard Connectors Feature Summary

• Vertical through-hole termination via wire wrap or PC pin options
• Gold-plated copper alloy contacts for reliable signal transmission
• Thermoplastic polyester insulator providing high dielectric strength

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Communication equipment backplanes
• Automotive electronics modules

Edgeboard Connectors Procurement Notes

Verify the specific termination style (wire wrap vs. PC pin) against the datasheet suffix, as the base model may support multiple variants. Confirm RoHS compliance status directly with the manufacturer documentation. Ensure the selected variant matches the required contact spacing and board thickness specifications for your PCB layout.

Edgeboard Connectors Selection Notes

Select this component when a 36-position vertical interface is required with a 3.175 mm pitch. Consider the 3 A current rating and 5 Gohm insulation resistance for circuit requirements. Verify that the thermoplastic polyester housing meets environmental constraints. Compare against other 346 series lengths if different position counts are needed.

Edgeboard Connectors Part Context

This part belongs to the EDAC 346 series of standard card edge connectors, which offer extensive design flexibility. The series provides various position counts and termination styles to tailor interconnect solutions. The 346-036-521-258 specifically addresses needs for medium-density vertical connections in compact assemblies.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the 346 series include parts with identical pitch and position counts but different termination suffixes, such as 346-036-521-201 or 346-036-521-802. Cross-series replacements require matching the 3.175 mm pitch and vertical orientation.
