3-5145090-3

Edgeboard Connectors Overview

The 3-5145090-3 is a dual female edgeboard connector manufactured by TE Connectivity AMP Connectors. It features 130 positions with a 0.050-inch (1.27mm) pitch, designed for through-hole mounting. The contacts are made of phosphor bronze with a gold finish, providing reliable signal transmission. The insulating material is polyphenylene sulfide (PPS), ensuring stability across an operating temperature range of -55°C to 85°C. This component supports standard edge cards and includes board lock features for secure installation.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for high-density signal interconnection
• Gold-plated phosphor bronze contacts ensure low resistance and corrosion resistance
• Polyphenylene sulfide insulation provides thermal stability and mechanical strength
• Through-hole termination with board lock mechanism for secure PCB attachment

Edgeboard Connectors Applications

• High-density electronic assemblies requiring robust signal connectivity
• Industrial control systems utilizing standard edge card interfaces
• Telecommunications equipment needing stable dual-row connections
• Automotive electronics modules requiring durable through-hole connectors

Edgeboard Connectors Procurement Notes

Verify the specific part number 3-5145090-3 against official TE Connectivity documentation to confirm current availability and lifecycle status. Ensure compatibility with target PCB layout and edge card specifications before ordering. Check for any recent product change notices or obsolescence alerts from the manufacturer. Confirm that the required quantity matches the standard packaging units provided by authorized distributors.

Edgeboard Connectors Selection Notes

Select this connector when a 130-position dual female interface is required with a 1.27mm pitch. It is suitable for applications demanding high reliability in varying temperatures due to its PPS construction. Consider the through-hole mounting style and board lock feature for mechanical stability. Ensure the mating edge card thickness aligns with the connector's acceptance range for optimal performance.

Edgeboard Connectors Part Context

This component belongs to the Standard Edge .050 series by TE Connectivity AMP Connectors. It is part of a broader family of edgeboard connectors designed for high-density applications. The 3-5145090-3 variant specifically offers 130 positions, distinguishing it from other pin counts within the same series. It shares common design principles with similar models but is unique in its position count and specific termination requirements.

Edgeboard Connectors Replacement Considerations

Consult TE Connectivity official substitution guides for verified alternative part numbers. Generic equivalents may not match the precise pitch, contact material, or insulation properties. Verify that any substitute maintains the same dual female configuration and through-hole mounting style. Cross-reference dimensions and electrical ratings to ensure functional compatibility.
