305-048-521-258

Edgeboard Connectors Overview

The EDAC Inc. 305-048-521-258 is a standard card edge connector from the 305 series, designed for dual-edge female mating configurations. It features 48 positions with a 3.96 mm (0.156 inch) pitch and supports board thicknesses ranging from 1.37 mm to 1.78 mm. The connector utilizes gold-plated copper alloy contacts with a 10.0 µin (0.25 µm) plating thickness and employs a solder pin termination method. Constructed with green thermoplastic polyester insulation, it offers a current rating of 5 A and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for secure card insertion
• Gold-plated copper alloy contacts ensure reliable conductivity
• Thermoplastic polyester insulation provides thermal stability

Edgeboard Connectors Applications

• Industrial control panel interconnections
• Telecommunications equipment backplanes
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm mechanical dimensions and contact finish specifications. Ensure compatibility with the target PCB card thickness and panel mounting requirements before procurement. Cross-reference the RoHS compliance status with current regulatory standards applicable to your region.

Edgeboard Connectors Selection Notes

Select this component when a dual-sided card edge interface is required for high-density signal routing. The 3.96 mm pitch accommodates standard industrial board layouts. Consider the vertical panel mount style and solder pin termination for robust mechanical fixation in vibration-prone environments.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which includes various header and card edge connectors. The series is characterized by its use of thermoplastic polyester materials and standardized spacing. Other variants in the series differ primarily in position count and specific flange characteristics while maintaining consistent electrical performance profiles.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC part numbers such as 305-048-521-202 and 305-048-500-201, which share similar form factors and electrical ratings. Verify that any alternative maintains the same 48-position count and dual-edge female configuration to ensure functional interchangeability.
