302-080-256-201

Edgeboard Connectors Overview

The EDAC Inc. 302-080-256-201 is a standard card edge connector from the 302 series, designed for dual-edge board applications. It features 80 positions with a contact spacing of 0.050 inches (1.27mm). The connector utilizes gold flash plated contacts made from copper alloy and employs a solder termination method. The housing is constructed from black polyamide (PA66) nylon and supports board thicknesses ranging from 0.051 to 0.071 inches (1.30mm to 1.80mm). It operates within a temperature range of -55°C to 85°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration with 80 gold-plated contacts for reliable signal transmission
• Straddle mount installation style compatible with non-specified dual-edge cards
• Constructed from durable black PA66 nylon insulation material

Edgeboard Connectors Applications

• High-density electronic interconnects requiring dual-edge card insertion
• Industrial control systems utilizing straddle-mounted PCB interfaces
• Communication equipment needing robust 1.27mm pitch connectivity

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct contact finish and housing color specifications. Confirm that the target application requires a straddle mount configuration rather than surface mount alternatives. Check for RoHS compliance status if environmental regulations apply to the end product. Ensure the receiving facility has appropriate handling procedures for high-pin-count connectors to prevent pin damage during storage or assembly.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count interface with fine 1.27mm pitch is required for dual-edge boards. The straddle mount design offers mechanical stability without requiring additional mounting hardware on the PCB. Consider the operating temperature range of -55°C to 85°C for environmental suitability. Verify that the host card thickness falls within the specified 1.30mm to 1.80mm tolerance for proper engagement.

Edgeboard Connectors Part Context

This part belongs to the EDAC 302 series, which specializes in standard card edge connectors with fine pitch capabilities. The series is characterized by its use of gold flash plating for corrosion resistance and low contact resistance. These connectors are typically used in scenarios demanding high reliability and frequent mating cycles in compact electronic assemblies.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 80-position count, 1.27mm pitch, and straddle mount form factor. Verify compatibility with existing PCB footprints and card thickness tolerances before substitution.
