302-110-621-201

Edgeboard Connectors Overview

The EDAC Inc. 302-110-621-201 is a card edge connector from the 302 Series, designed for dual-edge board mounting. It features 110 positions with female contacts and a 0.050 inch (1.27mm) pitch. The connector utilizes gold-plated cantilever contacts and a black polyamide (PA66) insulator. It supports card thicknesses between 0.051 and 0.071 inches (1.30mm to 1.80mm). Operating within a temperature range of -55°C to 85°C, it offers four rows of terminals and complies with RoHS3 standards.

Edgeboard Connectors Feature Summary

• Dual-edge configuration accommodates non-specified cards via cantilever contact design
• Gold-plated contacts ensure reliable signal transmission in high-density layouts
• Polyamide insulation provides structural stability across wide thermal ranges

Edgeboard Connectors Applications

• High-density backplane interconnects
• Industrial control system modules
• Telecommunications equipment interfaces

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 110-position count and dual-edge specification. Confirm compatibility with the target PCB stack-up and card thickness constraints. Ensure compliance with project-specific environmental regulations such as RoHS3. Cross-reference the manufacturer's datasheet for accurate mechanical dimensions and termination requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count interface with fine 1.27mm spacing is required. The dual-edge design maximizes connection density compared to single-edge alternatives. Verify that the operating temperature range meets the application's environmental demands. Ensure the PCB layout supports the specified mounting style and terminal row configuration.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 302 Series, which specializes in high-density card edge solutions. The series is characterized by its fine 0.050-inch pitch and robust construction suitable for demanding electronic environments. The 302-110 variant specifically addresses applications requiring extensive I/O connections within constrained spatial footprints.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 110-position count, 1.27mm pitch, and dual-edge geometry. Verify identical contact plating and insulation material properties. Check for equivalent mechanical mounting specifications and thermal ratings to ensure functional interchangeability without redesigning the host PCB.
