305-048-500-502

Edgeboard Connectors Overview

The EDAC 305-048-500-502 is a standard card edge connector from the 305 series, designed for dual-row female connections. It features 48 positions with a 3.96 mm (0.156 inch) pitch. The connector supports PCB thicknesses ranging from 1.37 mm to 1.78 mm and utilizes gold-plated copper alloy contacts with a thickness of 10.0 µin (0.25 µm). Rated for 5 A continuous current and 1800 VACrms insulation voltage, it operates within a temperature range of -40°C to +105°C. The housing is made of green thermoplastic polyester, offering high insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Utilizes semi-wire wrap termination style for reliable soldering
• Constructed with thermoplastic polyester insulation for durability

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standardized modular boards
• Test and measurement instrumentation with dual-row connectivity needs

Edgeboard Connectors Procurement Notes

Verify that the specific application requires a dual-row configuration with a 3.96 mm pitch before procurement. Confirm that the target PCB thickness falls within the specified 1.37 mm to 1.78 mm range to ensure proper mechanical engagement. Ensure compatibility with the required 5 A current rating and 1800 VACrms dielectric strength for the intended circuit environment. Check for RoHS compliance requirements if operating in regulated regions.

Edgeboard Connectors Selection Notes

Select this component when a dual-row female connector is necessary for non-specified card edge applications. The 3.96 mm pitch accommodates standard board layouts, while the gold plating ensures low contact resistance. Consider the vertical panel mount style if chassis integration is required. The wide operating temperature range makes it suitable for demanding environmental conditions compared to standard commercial-grade alternatives.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in modular electronic designs. The series offers various position counts and termination styles to support diverse interface requirements. The 305-048-500-502 specifically addresses high-density connection needs with its 48-position dual-row layout, providing a balance between signal count and physical footprint.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and row configuration but different position counts, such as 305-040-500-502 or 305-054-556-278, provided the pin count matches the design requirement. Verify that any alternative maintains the same 3.96 mm pitch and dual-row female contact type to ensure mechanical and electrical compatibility.
