G125-FV12005L0R

Overview

The Harwin G125-FV12005L0R is a Gecko-Latch series power-to-board connector designed for vertical surface mount applications. It features a 1.25 mm pitch with a 2x10 position configuration, totaling 20 contacts. The component utilizes female socket terminals plated with gold over copper alloy. Rated for 2 A current and 250 V/450 V voltage, it operates within a temperature range of -65 C to +150 C. The housing is constructed from polyamide (PA) with an insulation resistance of 10 GOhms.

Feature Summary

• Vertical SMD mounting style for compact board integration
• Gecko-Latch mechanical locking system for secure connection
• Gold-plated copper alloy contacts for reliable conductivity
• Polyamide housing material providing high thermal stability

Applications

• Power distribution in industrial control systems
• High-density server backplane connections
• Automotive electronics power interfaces
• Telecommunications equipment power modules

Procurement Notes

Verify the specific suffix 'L0R' against the manufacturer's latest datasheet to confirm reel packaging and tape specifications. Ensure compatibility with mating male headers from the same Gecko-Latch family. Check RoHS and REACH compliance status directly on the official product page before finalizing procurement orders.

Selection Notes

Select this part for applications requiring vertical orientation and space-constrained layouts. The 1.25 mm pitch allows for high pin density compared to standard connectors. Consider the 2 A current rating per contact when designing power traces. Verify that the mating connector supports the required latch mechanism for vibration resistance.

Part Context

This component belongs to the Harwin Gecko-Latch family, known for robust mechanical latching. It complements other G125 series parts like the G125-MS12005L2P male counterpart. The series is engineered for demanding environments where secure power delivery and small form factors are critical requirements.

Replacement Considerations

Direct substitutes include other Harwin G125 series receptacles with matching 1.25 mm pitch and 20 positions. Verify mechanical dimensions and latch type compatibility. Generic 1.25 mm connectors may lack the specific Gecko-Latch retention force.
