G125-MS11205L2R

Overview

The G125-MS11205L2R is a surface mount header connector from the Harwin Gecko-Latch series. It features a 1.25mm (0.049 inch) pitch with two rows and five positions per row, totaling ten contacts. The connector utilizes male pin contacts made of phosphor bronze with gold plating. Rated for 2A current and 450VAC/DC voltage, it employs a latch lock mechanism for secure mating. The housing is constructed from green polyamide material rated UL94 V-0, supporting an operating temperature range of -65°C to +150°C.

Feature Summary

• Surface mount design with vertical orientation for PCB integration
• Gecko-Latch locking system ensures secure mechanical retention
• Gold-plated phosphor bronze contacts for reliable conductivity
• Shrouded structure provides alignment and protection

Applications

• Wire-to-board interconnections
• Power distribution on printed circuit boards
• General electronic equipment signal routing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact configuration, insulation color, and packaging type. Ensure compatibility with automated pick-and-place assembly processes due to the surface mount termination style. Cross-reference the part number with the latest RoHS compliance documentation before finalizing procurement orders.

Selection Notes

Select this component when a low-profile, vertically oriented header with positive locking is required for board-to-wire connections. The 1.25mm pitch accommodates standard wire gauges while maintaining compact spacing. Consider the 2A current rating and high-temperature tolerance for applications requiring robust thermal performance in confined spaces.

Part Context

This part belongs to the Harwin Gecko-Latch family, designed for high-reliability applications. The series offers various configurations including different row counts, pin numbers, and mounting styles. The G125-MS variant specifically denotes a male header with surface mount termination and latch locking features within the broader Gecko product line.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Evaluate alternative connectors based on matching 1.25mm pitch, 2-row layout, male pin type, and SMT mounting requirements. Verify that any replacement maintains identical locking mechanisms and electrical ratings for functional equivalence.
