305-012-500-203

Edgeboard Connectors Overview

The EDAC Inc. 305-012-500-203 is a standard card edge connector from the 305 series, designed for dual female connections with 12 positions arranged in two rows. It features a contact spacing of 3.96 mm (0.156 inches) and accommodates printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). The connector utilizes gold-plated copper alloy contacts with a semi-bellows termination type for reliable signal transmission.

Edgeboard Connectors Feature Summary

• Dual row configuration supporting non-specified dual-edge card types
• Semi-bellows contact design ensures secure mating engagement
• Low profile insulator body constructed from thermoplastic polyester
• Gold plating on copper alloy contacts provides corrosion resistance

Edgeboard Connectors Applications

• Industrial control system interface modules
• Telecommunications equipment backplanes
• Embedded computing hardware interconnects

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 12-position dual-row configuration before ordering. Confirm compatibility with the target PCB thickness of 1.57 mm to ensure proper mechanical fit. Check RoHS3 compliance status if environmental regulations apply to the final assembly. Ensure the supplier provides official datasheets for accurate dimensional verification.

Edgeboard Connectors Selection Notes

Select this component when a low-profile, dual-edge card connector is required for panel or PCB mounting applications. The 3.96 mm pitch suits designs needing robust mechanical stability with semi-bellows contact retention. Consider the green insulator color for visual identification during assembly processes. Evaluate thermal operating ranges against the specified -40°C to +105°C limits.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors, which are widely used in high-reliability electronic assemblies. The series offers various position counts while maintaining consistent electrical and mechanical specifications across models. The 305-012 variant specifically addresses applications requiring twelve connection points in a compact dual-row format.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts for different position counts if pinout requirements change. Verify that substitute connectors maintain the same 3.96 mm pitch and 1.57 mm board thickness acceptance criteria.
