Overview
The G125-MH12005L7P is a male header connector from the Harwin Gecko-Latch series. It features a 1.25 mm pitch and a 2x10 position configuration arranged in two rows. The component utilizes a right-angle through-hole mounting style with solder pin termination. It includes a board lock mechanism for secure PCB attachment. The contacts are gold-plated phosphor bronze, rated for 2 A current at 250 V. Operating temperature ranges from -65 °C to +150 °C. The housing is green nylon with UL 94 V-0 flammability rating.
Feature Summary
- Gecko-Latch series design with integrated board lock mechanism
- Right-angle through-hole solder pin termination
- Gold-plated phosphor bronze contacts for reliable signal transmission
- Shrouded housing construction for wire-to-board applications
Applications
- Wire-to-board interconnects
- High-density electronic assemblies
- Industrial control systems
- Automotive electronics modules
Procurement Notes
Verify RoHS compliance status and REACH SVHC declarations prior to integration. Confirm that the specific ordering suffix corresponds to the required tape and reel packaging format. Ensure compatibility with existing assembly equipment for right-angle through-hole placement. Validate thermal resistance during reflow processes against the specified operating temperature range of -65 °C to +150 °C.
Selection Notes
Select this part when a shrouded, right-angle male header with board locking capability is required. The 1.25 mm pitch suits high-density layouts. Verify that the 2 A current rating meets circuit demands. Consider the Gecko-Latch series if mechanical retention via board lock is necessary. Compare against vertical variants if space constraints differ.
Part Context
This component belongs to the Harwin G125 Gecko-Latch family, designed for micro-miniature interconnect solutions. The series emphasizes reliability in harsh environments through robust latching mechanisms. The G125-MH12005L7P specifically addresses needs for angled, locked connections in compact electronic designs requiring durable signal pathways.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching pitch, row count, and locking mechanism specifications.
