345-072-521-158

Edgeboard Connectors Overview

The EDAC Inc. 345-072-521-158 is a card edge connector from the 345 series, designed for single-sided board applications. It features 72 positions with a 0.100 inch (2.54 mm) pitch and utilizes female contacts. The connector employs a through-hole termination method with wire wrap capabilities. Contact surfaces are gold-plated to a thickness of 10.0 µin (0.25 µm). The insulator material is thermoplastic polyester, colored green. It supports PCB thicknesses ranging from 0.054 to 0.070 inches (1.37 to 1.78 mm) and operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm pin count, termination style, and plating specifications. Ensure compatibility with target PCB thickness limits and mounting requirements before procurement. Cross-reference the RoHS status and environmental compliance data with current regulatory standards for the intended deployment region.

Edgeboard Connectors Selection Notes

Select this component when a single-row, high-density connection is required for vertical panel or chassis mounting. Confirm that the application environment stays within the specified thermal operating range. Validate that the wire wrap termination process aligns with the assembly line capabilities and that the contact pitch matches the design layout constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 345 series, which offers various configurations including dual-sided options and different termination styles. The series provides modular solutions for board-to-board and board-to-wire connections. This specific model represents a standard single-sided variant optimized for general-purpose electronic assemblies requiring durable mechanical retention.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 345 series parts with matching 72-position counts and single-sided layouts. Verify equivalent pitch and termination methods when considering cross-manufacturer alternatives. Ensure physical dimensions and flange characteristics match the existing enclosure design.
