895-078-520-208

Edgeboard Connectors Overview

The EDAC Inc. 895-078-520-208 is a dual-edge female card edge connector from the 895 series, designed for through-hole vertical mounting. It features 78 positions with a 0.100-inch (2.54mm) pitch across two rows. The contacts are made of copper alloy with gold plating and utilize a cantilever spring design. The insulator is constructed from Polyphenylene Sulfide (PPS), rated UL 94V-0, supporting an operating temperature range of -40°C to 125°C. It accommodates card thicknesses between 0.054 and 0.070 inches.

Edgeboard Connectors Feature Summary

• Cantilever spring contact design ensures reliable electrical connection for non-specified dual-edge cards.
• Polyphenylene sulfide (PPS) insulator provides high thermal stability and UL 94V-0 flammability rating.
• Gold-plated copper alloy contacts offer corrosion resistance and low contact impedance.
• Vertical through-hole mounting with panel-mount flange options for secure installation.

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connectivity
• Telecommunications equipment utilizing standard card edge modules
• Test and measurement instrumentation interfaces
• Consumer electronics internal module connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC 895 Series Ordering Guide to ensure correct termination style, flange configuration, and insulation material. Confirm that the required card thickness falls within the specified 0.054 to 0.070 inch range. Check RoHS3 compliance status if restricted substances are a project constraint. Ensure the selected variant matches the required mounting orientation and contact plating thickness specifications.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 0.100-inch pitch is required for vertical PCB mounting. The PPS insulator makes it suitable for applications exceeding standard temperature limits compared to other thermoplastics. Verify compatibility with the target circuit board's edge card thickness and ensure the cantilever contact type meets the mating force requirements of the application.

Edgeboard Connectors Part Context

This part belongs to the EDAC 895 Series, which offers various configurations including different row counts, termination styles, and flange options. The series is characterized by its use of PPS insulation for enhanced thermal performance. Other variants in the series may differ in position count, such as 16 or 92 positions, but share similar structural and material characteristics.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 78-position count, 0.100-inch pitch, dual-edge female configuration, and vertical through-hole mounting. Verify that any alternative part uses compatible cantilever contacts and PPS insulation to maintain thermal and mechanical integrity. Cross-reference with EDAC's 895 series ordering guide for equivalent suffix variations.
