306-034-400-158

Overview

The EDAC Inc. 306-034-400-158 is a card edge connector designed for dual-sided PCB insertion. It features 34 positions with a 0.156-inch (3.96mm) contact spacing and a 0.200-inch row pitch. The connector utilizes female, tin-plated contacts with a wire hole termination method for soldering. Constructed with a green thermoplastic polyester insulator, it supports nominal board thicknesses of 0.062 inches. Rated for operation between -40°C and +105°C, this component ensures reliable electrical connectivity in industrial applications.

Feature Summary

• Dual-edge female contact configuration for secure board retention
• Tin-plated wire hole terminals facilitate standard soldering processes
• Low-profile insulator body accommodates space-constrained designs
• Thermoplastic polyester housing provides thermal stability

Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Consumer electronics mainboard connections
• Medical device circuit integration

Procurement Notes

Verify the specific plating finish against official datasheets, as distributor listings may inconsistently describe the terminal surface as either tin or gold. Confirm that the required board thickness aligns with the 0.062-inch nominal specification to ensure proper mechanical engagement. Check RoHS compliance status directly with the manufacturer to meet regulatory requirements for your target market.

Selection Notes

Select this model when a dual-sided connection with a 0.156-inch pitch is required. Ensure the design accommodates the 0.200-inch row pitch and compatible board thickness. Consider the operating temperature range of -40°C to +105°C for environmental suitability. Verify that the wire hole termination method matches the available assembly equipment and soldering capabilities.

Part Context

This component belongs to the EDAC 306 Series, which specializes in card edge connectors with a 0.156-inch contact spacing. The series offers various position counts and termination styles to support diverse electronic assembly needs. The 306-034-400-158 variant specifically addresses applications requiring 34-position dual-edge connectivity with robust mechanical locking features.

Replacement Considerations

Direct substitutes within the same series include part numbers such as 306-032-400-158 and 306-043-400-158, which share identical spacing and form factors but differ in position count. Cross-series replacements require careful verification of pitch, row spacing, and mounting dimensions to ensure mechanical compatibility.
