305-030-521-204

Edgeboard Connectors Overview

The EDAC Inc. 305-030-521-204 is a standard card edge connector from the 305 series, designed for reliable signal transmission in electronic assemblies. It features a dual-edge configuration with 30 positions and a 0.100-inch (2.54mm) pitch. The connector utilizes gold-plated copper alloy contacts housed in a black thermoplastic polyester body. Rated for 5A current at temperatures ranging from -40°C to +105°C, it supports PCB thicknesses of 1.57mm. This panel-mount receptacle ensures secure mating with double-sided card edges.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates double-sided card edges for enhanced signal integrity
• Gold-plated copper alloy contacts provide corrosion resistance and low contact impedance
• Thermoplastic polyester insulation offers high dielectric strength and thermal stability
• Panel mount installation style facilitates secure integration into chassis or enclosure systems

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Medical device circuit board interfaces
• Automotive electronics modules

Edgeboard Connectors Procurement Notes

Verify that the specific suffix '204' corresponds to the 0.100 inch pitch variant, as other suffixes in the 305 series may indicate different pitches such as 0.156 inches. Confirm RoHS compliance status and ensure the supplier provides original manufacturer documentation. Cross-reference the pin count and termination type against the official datasheet to prevent mismatching with similar models like the 305-030-521-504 which differs in pitch.

Edgeboard Connectors Selection Notes

Select this component when a 0.100 inch pitch is required for double-sided card edge applications. Ensure the host PCB thickness aligns with the specified 1.57mm requirement for proper mechanical engagement. Consider the 5A current rating and operating temperature range to verify suitability for the intended electrical load and environmental conditions compared to single-row alternatives.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series of standard card edge connectors, which are widely used in general-purpose electronic applications. The series offers various configurations including single and dual rows with different pitches. The 305-030-521-204 specifically represents a 30-position dual-edge variant within this family, distinguished by its finer 0.100 inch spacing compared to the more common 0.156 inch variants found in the same series.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC 305-030-521-202 and 305-030-521-203, which share identical electrical and mechanical specifications. Verify that any replacement maintains the 0.100 inch pitch and dual-edge female contact configuration to ensure compatibility with existing card edge designs.
