837-020-542-104

Edgeboard Connectors Overview

The EDAC Inc. 837-020-542-104 is a single-row female card edge connector designed for through-hole mounting. It features 20 positions with a 0.156-inch (3.96mm) contact spacing. The connector utilizes copper alloy cantilever contacts with a gold finish, specifically 10.0µin (0.25µm) thick, to ensure reliable signal transmission. The insulator is constructed from green diallyl phthalate (DAP), providing stability across an operating temperature range of -40°C to 125°C. This component supports board thicknesses between 0.054 and 0.070 inches.

Edgeboard Connectors Feature Summary

• Single-edge female receptacle configuration for non-specified card types
• Gold-plated cantilever contacts for durable electrical connection
• High-temperature DAP insulator material for thermal stability

Edgeboard Connectors Applications

• Industrial control systems requiring high-temperature reliability
• Telecommunications equipment interface connections
• Automotive electronic module interconnects

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffix codes to ensure correct termination style and tail length specifications. Confirm that the target application board thickness falls within the specified 0.054 to 0.070 inch range. Check RoHS compliance status against current regulatory requirements for the destination market. Ensure storage conditions maintain integrity of the gold plating before assembly.

Edgeboard Connectors Selection Notes

Select this model when a single-row, 20-position female connector is required for vertical through-hole installation. The 0.156-inch pitch suits applications needing robust mechanical retention without soldering the connector directly to the board. Consider the high-temperature rating if the environment exceeds standard commercial limits. Verify compatibility with the specific card edge profile and thickness constraints of the mating PCB.

Edgeboard Connectors Part Context

This component belongs to the EDAC 837 Series, a line of high-temperature card edge connectors. The series is characterized by its use of diallyl phthalate insulators and cantilever contact designs. These connectors are engineered for demanding environments where standard plastic materials might fail. The 837 series offers various position counts and termination options to accommodate diverse board layout requirements.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 837 series variants such as 837-020-542-202 for dual-row alternatives. Verify dimensional compatibility with existing panel cutouts and board stack-ups. Ensure that any substitute maintains the same contact spacing and termination method to preserve assembly tooling and process validity.
