Overview
The Harwin G125-MV12605M3P is a Gecko-SL series male pin header featuring 26 positions in a dual-row configuration. It utilizes a 1.25 mm pitch and supports through-hole solder termination with straight mounting orientation. The connector is rated for 2 A current and 450 V voltage, operating within a temperature range of -65 °C to +150 °C. Contacts are gold-plated beryllium copper housed in green nylon. Mated stacking heights are specified at 7.25 mm and 7.33 mm.
Feature Summary
- Provides a low-profile, dual-row interconnect solution suitable for compact board-to-board or cable mating applications.
- Features reverse fixing mechanisms integrated into the housing design for secure installation.
- Utilizes gold-plated contacts on beryllium copper substrates to ensure reliable signal transmission.
Applications
- Compact electronic device interconnections
- Board-to-board stacking assemblies
- Cable mating configurations
Procurement Notes
Verify the specific suffix 'M3P' against official datasheets to confirm the inclusion of reverse fix features and exact housing dimensions. Ensure compatibility with mating sockets regarding stacking height requirements of 7.25 mm or 7.33 mm. Cross-reference RoHS and REACH compliance status directly from manufacturer documentation prior to procurement.
Selection Notes
Select this component when a 1.25 mm pitch male header with 26 positions is required for high-density applications. Consider the 450 V rating and 150 °C thermal limit for suitability in demanding environments. Verify that the through-hole mounting style and straight orientation align with the PCB layout constraints.
Part Context
This part belongs to the Harwin Gecko-SL family, designed for space-constrained electronics. The series emphasizes low profile and robust mechanical retention. The G125-MV12605M3P specifically addresses needs for dual-row male headers with integrated fixing mechanisms, distinguishing it from standard unsecured variants.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Evaluate other Gecko-SL male headers with matching 1.25 mm pitch and 26-position counts only after verifying mechanical and electrical parameter alignment.
