G125-FV21005L0P

Overview

The G125-FV21005L0P is a Gecko-Latch series power-to-board connector manufactured by Harwin. It features a 1.25 mm pitch and a two-row configuration with three positions. The component utilizes female socket contacts made from copper alloy with gold plating, rated for 2 A current and 120 V or 240 V voltage. Designed for through-hole installation at a straight angle, it employs solder pin termination. The housing is constructed from thermoplastic material, supporting an operating temperature range from -65 °C to +150 °C.

Feature Summary

• Integrated latch mechanism ensures secure mating retention within the Gecko-Latch system.
• Shrouded design provides alignment guidance and environmental protection for contacts.
• Gold-plated copper alloy contacts offer reliable conductivity and corrosion resistance.

Applications

• Power distribution modules in industrial equipment
• Internal connections in consumer electronics assemblies
• Control board interconnects in automotive systems

Procurement Notes

Verify the specific contact count and tail length against project requirements, as the Gecko-Latch series offers various position configurations. Confirm that the through-hole mounting style and straight orientation align with the PCB layout constraints. Ensure the thermal rating of the thermoplastic housing meets the operational environment standards. Cross-reference the datasheet for precise mechanical dimensions to validate clearance and spacing on the target circuit board.

Selection Notes

Select this component when a secure latching connection is required for power delivery in compact spaces. The 1.25 mm pitch allows for high-density arrangements while maintaining adequate spacing for safety ratings. Consider the shrouded structure for improved handling during assembly. Evaluate the gold plating thickness if harsh environmental conditions are present. Compare against non-latching variants if cost reduction is prioritized over retention force.

Part Context

This part belongs to the Harwin Gecko-Latch family, designed for robust board-to-board and power-to-board applications. The series emphasizes secure connection reliability through its unique locking feature. It complements male header counterparts to form complete interconnect solutions. The product line supports various row counts and pitch options to accommodate diverse electronic design needs.

Replacement Considerations

Direct substitutes within the same series include G125-FV22005L0P (20 positions) and G125-FV13405L0P (34 positions). Verify compatibility with corresponding male headers such as G125-MV21605L0P. Ensure mechanical fit and electrical ratings match before substitution.
