176139-2

Edgeboard Connectors Overview

The TE Connectivity AMP Connectors part number 176139-2 is a Standard Card Edge connector designed for edgeboard applications. It features a female contact configuration with 98 positions arranged in a dual combination of 18 and 31 pins across two rows. The connector utilizes a 0.100-inch (2.54mm) pitch and supports board thicknesses ranging from 0.054 to 0.070 inches. Constructed with phosphor bronze contacts plated with gold, it ensures reliable signal transmission. The housing is made of reinforced polyester, colored black, and rated UL94 V-0 for flammability.

Edgeboard Connectors Feature Summary

• Dual-combination pin layout accommodating specific card edge profiles
• Gold-plated phosphor bronze contacts for corrosion resistance
• Reinforced polyester insulator providing structural stability
• Through-hole termination method for secure PCB mounting

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the current lifecycle status before procurement as availability varies by region. Confirm that the target application requires the specific 18/31 dual-combination geometry rather than standard uniform rows. Ensure the printed circuit board design accommodates the specified 0.100-inch pitch and compatible board thickness range. Check for RoHS compliance documentation if required by project specifications.

Edgeboard Connectors Selection Notes

Select this component when a mixed-row pin count is necessary for specific signal routing requirements. The dual-combination design allows for flexible I/O distribution on constrained board edges. Consider the through-hole installation method for robust mechanical retention compared to surface mount alternatives. Evaluate the gold plating thickness against environmental exposure conditions to ensure long-term reliability.

Edgeboard Connectors Part Context

This connector belongs to the Standard Edge II series within the TE Connectivity AMP portfolio. It serves as a specialized interconnect solution for high-density edgeboard applications where standard uniform row connectors are insufficient. The product represents a legacy design option for systems requiring specific pin configurations not covered by newer generation arrays.

Edgeboard Connectors Replacement Considerations

No direct public substitute part numbers are confirmed for this specific dual-combination configuration. Designers should evaluate custom solutions or modified layouts if this obsolete or low-stock item becomes unavailable.
