845-126-558-204

Edgeboard Connectors Overview

The EDAC Inc. 845-126-558-204 is a dual-edge female card edge connector from the 845 High Temp series. It features 126 positions with a 0.100 inch (2.54 mm) contact spacing and 0.200 inch (5.08 mm) row spacing. The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). It utilizes gold-plated contacts on a copper alloy substrate housed in a green DAP insulator body. Designed for through-hole mounting via wire wrap termination, it supports an operating temperature range of -40°C to 125°C.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure that the procurement channel provides traceability for the 845 series components. Confirm that the received units match the 126-position count and dual-edge geometry required for the target PCB design. Cross-reference the datasheet revision date to guarantee compliance with current manufacturing standards.

Edgeboard Connectors Selection Notes

Select this component when a high-temperature rating is critical for the application environment. The 0.100-inch pitch requires compatible PCB layout guidelines for signal integrity. Verify that the host system can accommodate the high-profile insulator body dimensions. Consider the wire wrap termination method during assembly planning to ensure proper mechanical retention and electrical contact.

Edgeboard Connectors Part Context

This part belongs to the EDAC 845 High Temperature series, designed for reliability in harsh conditions. The series offers various position counts and configurations. The 845-126 variant specifically addresses needs for higher density connections within the standard .100-inch pitch framework while maintaining the structural integrity required for ruggedized applications.

Edgeboard Connectors Replacement Considerations

Consult official EDAC substitution guides for direct replacements. Generic equivalents may not match the high-temperature ratings or specific termination requirements. Verify dimensional compatibility before considering alternative suppliers.
