Overview
The Harwin G125-MV15005L1P is a Gecko-SL series male pin header connector designed for vertical through-hole mounting. It features a 1.25 mm pitch with 50 positions arranged in a dual-row configuration (2x25). The contacts are constructed from phosphor bronze with gold plating, rated for 2 A current and 250 V/450 V voltage. The housing is made of green polyamide (PA) plastic. Operating temperature ranges from -65 °C to +150 °C, with an insulation resistance of 10 GOhms.
Feature Summary
- Jackscrew locking mechanism provides secure mechanical retention
- Low-profile dual-row design suitable for stacking applications
- Reverse fix tab orientation for specific board layout requirements
Applications
- Board-to-board interconnects
- Cable-to-board connections
- Stacked circuit module assembly
Procurement Notes
Verify the specific ordering suffix 'L1' against the official Harwin datasheet to confirm reverse fix tab orientation and lead time availability. Ensure compatibility with mating connectors within the G125-FC or G125-MH series. Confirm RoHS compliance status via the manufacturer's environmental declaration before final procurement.
Selection Notes
Select this component when a low-profile, high-density connection is required with positive locking security. The 1.25 mm pitch allows for compact layouts compared to standard 2.54 mm headers. Verify that the PCB footprint supports the 3.3 mm end-tail length for through-hole soldering and that the jack-screw clearance does not conflict with adjacent components.
Part Context
This part belongs to the Harwin Gecko-SL family, which specializes in screw-locking connectors for harsh environments. The G125 series offers a 1.25 mm pitch, balancing density with reliability. The MV designation indicates a vertical male pin header, while the SL suffix confirms the inclusion of jackscrew locking features for vibration resistance.
Replacement Considerations
Compatible mating parts include G125-FC15005F1-0450L cables and G125-MH15005M3P right-angle headers. Direct substitutes require identical 1.25 mm pitch, 50-position dual-row format, and jackscrew locking capability. Generic 1.25 mm headers lack the specific locking mechanism and may not fit the reverse-fix tab requirement.
