Overview
The Harwin M20-7831746 is a 14-position, dual-row PCB socket connector from the M20 series. It features a 2.54 mm pitch and is designed for board-to-board applications. The unit utilizes through-hole termination with nickel-plated tin contacts made of phosphor bronze. The housing is constructed from nylon, rated UL94V-0, supporting a current rating of 12A and operating temperatures between -55°C and 105°C.
Feature Summary
- Dual-row configuration for high-density interconnects
- Robust double-beam contact design for reliable electrical connection
- High-temperature liquid crystal polymer or nylon housing for thermal stability
- Through-hole mounting for secure PCB attachment
Applications
- Board-to-board interconnection systems
- Industrial control modules
- Test and measurement equipment interfaces
Procurement Notes
Verify the specific suffix against official Harwin documentation to confirm pin count and row configuration. Ensure compatibility with mating header specifications regarding height and tolerance. Confirm RoHS compliance status for the specific manufacturing batch prior to integration into regulated assemblies.
Selection Notes
Select this component when a dual-row, 2.54mm pitch socket is required for rigid board-to-board connections. Consider the 12A current rating and -55°C to 105°C temperature range for environmental suitability. Verify that the through-hole footprint matches the target PCB layout constraints.
Part Context
This part belongs to the Harwin M20 series, which provides industrial-standard connectors for demanding environments. The series offers various configurations including single and dual rows, accommodating different density requirements while maintaining consistent 2.54mm spacing and robust mechanical properties.
Replacement Considerations
Consult official Harwin cross-reference guides for verified substitutes. Generic equivalents may not match the specific double-beam contact geometry or housing material ratings required for original equipment reliability.
