305-050-555-208

Edgeboard Connectors Overview

The EDAC 305-050-555-208 is a standard card edge connector from the 305 Series, designed for vertical panel mounting. It features 50 positions arranged in two rows with a 3.96 mm (0.156 inch) pitch. The connector utilizes solder lug termination and gold-plated copper alloy contacts to ensure reliable signal transmission. It accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Rated for 5 A continuous current, it operates within a temperature range of -40°C to +105°C and offers an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Vertical panel mount design with solder lug termination for secure board attachment
• Dual-row configuration providing 50 contact positions at a 3.96 mm pitch
• Gold-plated copper alloy contacts ensuring corrosion resistance and conductivity
• Compatible with 1.57 mm nominal thickness PCBs for standard card edge applications

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Test and measurement equipment utilizing standard card edge modules
• Communication hardware needing high-reliability signal routing
• Automotive electronics interfaces demanding stable electrical connections

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 50-position dual-row configuration and 3.96 mm pitch before procurement. Confirm that the installation method aligns with vertical panel mounting requirements rather than board-edge straddle mount variants. Ensure the target application supports the specified 1.57 mm PCB thickness tolerance. Check RoHS compliance status against current regulatory standards for the intended market. Validate that the solder lug termination type is compatible with the assembly process used.

Edgeboard Connectors Selection Notes

Select this component when a vertical panel-mount interface is required for standard thickness cards. The 305 series provides a balance of durability and electrical performance for industrial environments. Consider the 5 A current rating and wide operating temperature range for harsh conditions. Compare against other EDAC series if different mounting styles or contact counts are needed. Ensure the gold plating meets the specific wear cycle requirements of the mating card.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 Series, which includes various configurations of card edge connectors. The series is characterized by its use of thermoplastic insulators and standardized spacing dimensions. Other parts in this family may differ in position count, row configuration, or mounting style. The 305-050-555-208 specifically denotes the 50-position variant with vertical panel mounting and solder lug termination.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the EDAC 305 series include 305-050-556-208 and 305-050-500-202, though these may feature different mounting types such as straddle mount or flange variations. Verify mechanical fit and electrical specifications before swapping. Cross-brand replacements require careful evaluation of pitch, height, and contact material compatibility.
