2-5145090-2

Edgeboard Connectors Overview

The 2-5145090-2 is a dual female edgeboard connector manufactured by TE Connectivity AMP Connectors. It features 100 positions with a 0.050-inch (1.27mm) contact spacing and two rows of contacts. Designed for through-hole mounting, the connector utilizes phosphor bronze contacts with a gold finish to ensure reliable signal transmission. The insulating material is polyphenylene sulfide (PPS), providing stability across an operating temperature range of -55°C to 85°C. It accommodates card thicknesses between 0.054 inches and 0.070 inches (1.37mm to 1.78mm).

Edgeboard Connectors Feature Summary

• Dual female configuration designed for high-density edgeboard applications.
• Gold-plated phosphor bronze contacts ensure durable electrical performance.
• Polyphenylene sulfide insulation offers thermal and chemical resistance.

Edgeboard Connectors Applications

• Industrial control systems requiring robust edge connections.
• Telecommunications equipment utilizing standard edge cards.
• Test and measurement instrumentation interfaces.

Edgeboard Connectors Procurement Notes

This component is officially listed as obsolete or not recommended for new designs by the manufacturer. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors. Buyers must confirm the specific manufacturing date code and storage conditions to ensure the integrity of the gold plating and solderability before integration into production lines.

Edgeboard Connectors Selection Notes

Engineers selecting this part must verify compatibility with existing PCB layouts due to its specific 0.050-inch pitch and dual-row arrangement. The through-hole termination method requires appropriate drilling specifications. Given its discontinued status, alternative sourcing strategies or redesigns using current TE Connectivity series may be necessary for long-term supply chain stability.

Edgeboard Connectors Part Context

Part of the Standard Edge .050 series, this connector represents a legacy solution for board-to-board interconnections. It belongs to the broader AMP Connectors portfolio known for standardized industrial interfaces. The 100-position count makes it suitable for data-heavy applications within constrained form factors typical of mid-generation electronic hardware architectures.

Edgeboard Connectors Replacement Considerations

As this part is obsolete, direct substitutes are limited. Users should consult TE Connectivity for current equivalent series with matching 0.050-inch pitch and 100-position dual female configurations. Cross-referencing mechanical dimensions and pinout definitions is essential when evaluating potential replacement components from other manufacturers.
