345-066-521-203

Edgeboard Connectors Overview

The EDAC Inc. 345-066-521-203 is a standard card edge connector from the 345 series, designed for dual-edge board applications. It features 66 positions arranged in two rows with a 2.54 mm (0.100 inch) pitch. The connector utilizes female copper alloy contacts with gold plating and is rated for 3 A current. Constructed with thermoplastic polyester housing, it supports through-hole mounting in a vertical orientation. The unit operates within a temperature range of -40°C to +105°C and provides an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration for non-specified card types
• Gold-plated copper alloy contacts ensuring reliable signal transmission
• Vertical through-hole mounting with integrated flange features

Edgeboard Connectors Applications

• Industrial control system interconnects
• Medical device circuit board connections
• Agricultural technology equipment interfaces

Edgeboard Connectors Procurement Notes

Verify RoHS compliance status and REACH registration details before procurement. Confirm that the specific suffix indicates the correct flange and termination style required for the assembly. Ensure the manufacturing date code aligns with project timelines, as availability may be restricted in certain regions. Cross-reference the datasheet for precise mechanical dimensions to validate fitment within the target enclosure constraints.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge, 66-position connector with a 2.54 mm pitch is required. The vertical through-hole design suits PCBs needing direct board-to-board or backplane connections. The gold-plated contacts are suitable for environments requiring corrosion resistance. Verify that the board thickness falls within the specified operational range for proper contact engagement.

Edgeboard Connectors Part Context

This part belongs to the EDAC 345 series of standard card edge connectors. The series offers various position counts and row configurations to accommodate different board densities. The 345 series is characterized by its robust thermoplastic polyester housing and standardized 0.100-inch spacing, making it a common choice for general-purpose electronic interconnect solutions across multiple industries.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include part numbers such as 345-066-521-288 and 345-066-521-258. These alternatives share the same 66-position count and 2.54 mm pitch but may differ in flange specifications or termination styles. Verify mechanical compatibility and electrical ratings before swapping components.
