305-022-521-502

Edgeboard Connectors Overview

The EDAC Inc. 305-022-521-502 is a dual-row female card edge connector from the 305 Series, designed for panel and through-hole mounting. It features 22 positions with a 0.156-inch (3.96mm) pitch. The contacts are made of copper alloy with gold plating and utilize a semi-crimping termination type for soldering. The housing is constructed from thermoplastic polyester and is green in color. It supports board thicknesses ranging from 0.054 to 0.070 inches (1.37mm to 1.78mm). The connector operates within a temperature range of -40°C to +105°C and meets RoHS3 standards.

Edgeboard Connectors Feature Summary

• Dual-row configuration with 22 positions for high-density signal transmission
• Gold-plated copper alloy contacts ensure reliable conductivity and corrosion resistance
• Semi-crimping contact design provides secure mechanical retention for solder termination
• Thermoplastic polyester insulation offers durability across a wide operating temperature range

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Medical equipment interfaces needing reliable signal connections
• Agricultural technology hardware exposed to harsh environmental conditions
• General-purpose electronic assemblies utilizing standard card edge boards

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to confirm exact pin count, plating thickness, and flange characteristics. Ensure compatibility with target PCB thickness specifications before procurement. Confirm RoHS3 compliance status if required by project regulations. Cross-reference the manufacturer part number with distributor listings to validate current availability and lead times. Check for any regional distribution restrictions that may affect supply chain logistics.

Edgeboard Connectors Selection Notes

Select this component when a dual-row female connector with a 3.96mm pitch is required for panel installation. Verify that the mating card edge board thickness falls within the specified 1.37mm to 1.78mm range. Consider the 22-position count for circuit density requirements. Ensure the operating environment stays within the -40°C to +105°C thermal limits. Confirm that the gold-plated semi-crimping termination aligns with the assembly's soldering process capabilities.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 Series, which offers various mounting options and row configurations. The series is designed for standard card edge applications, providing versatile solutions for different industry sectors. The 305-022 variant specifically addresses needs for moderate pin counts with dual-row connectivity. It shares common family traits such as thermoplastic insulation and gold contact plating with other models in the lineup.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with matching 22-position dual-row specifications, such as 305-022-556-568 or 305-022-521-501, provided electrical and mechanical parameters align. Verify pitch, row count, and termination style before substitution. Alternative manufacturers may offer similar connectors but require thorough validation of interface dimensions and material properties.
