Overview
The EDAC Inc. model 306-021-400-102 is a standard card edge connector from the 306 series, designed for dual female termination. It features 42 positions with a pitch of 0.156 inches (3.96 mm). The connector supports panel mount installation at a vertical angle and utilizes solder pin end types. Constructed with copper alloy contacts and thermoplastic polyester insulation, it accommodates board thicknesses within specified ranges.
Feature Summary
- Dual female contact configuration for reliable signal transmission
- Vertical panel mount design for secure structural integration
- Solder pin termination for robust PCB attachment
Applications
- Industrial control systems requiring high-density interconnects
- Telecommunications equipment backplanes
- Test and measurement instrumentation modules
Procurement Notes
Verify the specific ordering suffix to confirm contact plating and flange characteristics, as these attributes vary across the 306 series. Confirm that the target application requires a dual female configuration rather than single-sided variants. Ensure compatibility with the intended PCB stack-up and mounting hardware before finalizing procurement orders.
Selection Notes
Select this component when a vertical, dual-sided connection is required for thick circuit boards. The 0.156-inch pitch allows for higher density compared to standard 0.100-inch options. Verify that the housing material meets environmental requirements and that the solder pin style aligns with the assembly process capabilities.
Part Context
This part belongs to the EDAC 306 series of standard card edge connectors. The series provides various position counts and termination styles. The 306-021-400-102 specifically denotes a 42-position dual female variant with standard mounting features, distinguishing it from single-row or rack-and-panel alternatives in the manufacturer's portfolio.
Replacement Considerations
Cross-reference with other 306 series parts such as 306-021-421-102 if gold plating is preferred over tin. Ensure mechanical dimensions match exactly when substituting.
