2332139-2

Edgeboard Connectors Overview

TE Connectivity AMP Connectors part number 2332139-2 is a dual-edge card edge connector designed for surface mount installation. It features 140 positions arranged in two rows, with a contact pitch of 0.024 inches (0.60 mm). The housing is black and constructed from liquid crystal polymer (LCP), supporting a board thickness of 0.062 inches (1.57 mm). Contacts are made of copper alloy with a gold finish, specifically 15.0 µin (0.38 µm) thick. The component operates within a temperature range of -55°C to +85°C and utilizes a solder termination method.

Edgeboard Connectors Feature Summary

• Dual-edge configuration providing 140 female contacts across two rows for high-density interconnect applications.
• Surface mount design compatible with pick-and-place assembly processes and board rail guidance.
• Gold-plated copper alloy contacts ensure reliable signal transmission and corrosion resistance.
• Liquid crystal polymer insulation offers thermal stability and mechanical strength for robust mounting.

Edgeboard Connectors Applications

• High-density backplane connections
• Industrial control system interfaces
• Telecommunications equipment modules

Edgeboard Connectors Procurement Notes

Verify the specific contact finish thickness against current manufacturer documentation, as sources indicate variations between 15.0 µin and 30.0 µin. Confirm that the selected variant matches the required board thickness of 0.062 inches. Ensure compatibility with standard surface mount reflow profiles. Check for any recent product change notices regarding material composition or packaging specifications before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count, low-profile connection is required for double-sided edge cards. The 0.60 mm pitch allows for significant I/O density in constrained spaces. Consider the LCP material properties for environments requiring higher thermal resistance compared to standard thermoplastics. Verify that the surface mount footprint aligns with the PCB design guidelines for the Sliver 2.0 series.

Edgeboard Connectors Part Context

This connector belongs to the TE Connectivity Sliver 2.0 series, which specializes in high-density card edge solutions. The series is engineered for applications demanding reliable performance in compact form factors. The 2332139-2 variant specifically addresses needs for 140-position dual-edge interfaces, offering a standardized solution for modern electronic systems requiring robust mechanical and electrical connectivity.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include part numbers such as 2332139-7, which shares identical physical dimensions and pin count configurations. When replacing, ensure that the alternative part maintains the same 0.024-inch pitch and dual-edge female contact type to guarantee mechanical fit and electrical continuity without redesigning the host board.
