306-025-421-103

Overview

The EDAC Inc. 306-025-421-103 is a standard card edge connector from the 306 series, designed for vertical panel mount applications. It features a single row of 25 positions with a 3.96 mm (0.156 inch) contact spacing. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm. Constructed with copper alloy contacts and a thermoplastic polyester insulator, it offers gold-plated terminals rated for 5 A current. The unit operates within a temperature range of -40°C to +105°C.

Feature Summary

• Vertical panel mount design for secure board integration
• Single centerline row configuration for standardized connectivity
• Gold-plated copper alloy contacts ensuring reliable signal transmission
• Thermoplastic polyester housing providing thermal stability

Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument interfaces
• Embedded computing module connections

Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact plating thickness and material specifications. Confirm that the target application requires the 3.96 mm pitch and 1.57 mm board thickness compatibility. Ensure environmental ratings meet operational temperature requirements. Cross-reference the manufacturer part number with authorized distributor catalogs to validate current availability status and compliance certifications such as RoHS.

Selection Notes

Select this component when a single-row, high-current card edge interface is required for panel-mounted assemblies. The 3.96 mm spacing accommodates thicker PCBs compared to finer pitches. Verify that the vertical orientation aligns with chassis layout constraints. Consider the thermoplastic insulation properties for thermal management needs. Ensure the 5 A rating suffices for the intended electrical load without derating.

Part Context

This connector belongs to the EDAC 306 series, which specializes in standard density card edge solutions. The series provides robust interconnect options for various industrial and commercial applications requiring reliable board-to-board or board-to-panel connections. The 306 series is characterized by its consistent dimensional standards and durable construction materials suitable for repeated mating cycles.

Replacement Considerations

Compatible substitutes within the same series include 306-025-520-107 and 306-025-421-102, provided they match the required pin count and mounting style. Verify that alternative part numbers maintain identical spacing and board thickness tolerances before substitution.
