305-044-556-203

Edgeboard Connectors Overview

The EDAC Inc. 305-044-556-203 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 44 positions with a 3.96 mm (0.156 inch) pitch and supports two rows of contacts. The connector utilizes gold-plated copper alloy terminals and accepts PCB thicknesses between 1.37 mm and 1.78 mm. Rated for 5 A continuous current and 1800 VACrms, it operates within a temperature range of -40°C to +125°C. The housing is constructed from thermoplastic material, providing reliable insulation and mechanical stability for panel-mounted installations.

Edgeboard Connectors Feature Summary

• Dual-row configuration with 44 positions for high-density interconnects
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Accepts between-contact and in-contact polarizing keys for secure alignment
• Straddle mount design facilitates robust panel installation

Edgeboard Connectors Applications

• Industrial control systems requiring durable edge connections
• Telecommunications equipment utilizing dual-edge boards
• Test and measurement instrumentation interfaces
• Automotive electronics modules

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 44-position configuration and 3.96 mm pitch before integration. Confirm compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm to ensure proper contact engagement. Check for RoHS compliance status if environmental regulations apply to the end product. Ensure that the mounting style aligns with the mechanical constraints of the enclosure design.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with a 3.96 mm pitch is required for panel-mounted applications. The 5 A current rating and 1800 VACrms voltage capability make it suitable for moderate power and signal applications. Consider the straddle mount feature if space constraints or vibration resistance are critical factors in the system architecture.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which offers various position counts and mounting options for card edge applications. The series is characterized by its standardized 3.96 mm pitch and robust construction. Similar models in the series may differ in position count, such as 12, 14, 44, 54, or 70 positions, while maintaining consistent electrical and mechanical specifications.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and row configuration but different position counts, such as 305-012-556-204 or 305-054-556-278. Verify mechanical fit and pinout compatibility before substitution. Alternative manufacturers may offer similar connectors, but dimensional and electrical verification is essential.
