305-054-555-212

Edgeboard Connectors Overview

The EDAC Inc. 305-054-555-212 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 54 positions arranged in a dual-row configuration with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Contacts are constructed from copper alloy with gold plating on the mating area, while tails utilize tin plating over nickel underplating for solder termination. The insulator body is made of green thermoplastic polyester, providing an insulation resistance of 5 GOhms. It supports a continuous current rating of 5 A and withstands 1800 VACrms, operating within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 54-position dual-row specification before ordering. Confirm compatibility with the target PCB thickness of 1.57 mm to ensure proper mechanical fit. Check regional availability as distribution status may vary by location. Ensure that the gold-plated contact finish meets the application's corrosion resistance requirements. Validate that the vertical panel mount style aligns with the enclosure design constraints.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with 54 positions is required for panel mounting. The 3.96 mm pitch suits applications where space efficiency is balanced with high pin count needs. Consider the 5 A current rating for power distribution or signal integrity in moderate-load environments. The vertical orientation facilitates direct board insertion into panel openings. Verify that the green thermoplastic insulator material meets any specific color coding or flame retardancy standards required by the system design.

Edgeboard Connectors Part Context

This connector belongs to EDAC's 305 series, which offers various position counts and row configurations. The series is characterized by its low-profile insulator body and compatibility with polarizing keys. Similar parts in the series include variants with different position counts such as 305-048-520-212 or 305-054-556-278, allowing designers to scale connectivity options while maintaining consistent mechanical and electrical characteristics across the product line.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-054-556-278, which shares identical positioning and pitch but may differ in specific packaging or minor material specifications. Cross-series replacements like 345-054-555-212 offer additional termination or mounting options but require verification of mechanical interface compatibility. Always confirm that alternative parts maintain the 54-position dual-row layout and 3.96 mm pitch to ensure interchangeability without redesigning the host PCB.
