Overview
The M20-7883246 is a 64-position, single-row PCB socket connector from the Harwin M20 series. It features a 2.54 mm pitch and utilizes through-hole right-angle mounting for secure board attachment. The housing is constructed from UL94 V-0 rated high-temperature liquid crystal polymer (LCP), ensuring thermal stability during soldering processes. Contacts are made of beryllium copper with nickel plating and a tin finish to provide reliable electrical connections.
Feature Summary
- Right-angle through-hole mounting configuration for space-constrained vertical board connections
- High-temperature LCP housing material compatible with standard surface mount reflow profiles
- UL94 V-0 flame rating for enhanced fire safety in electronic assemblies
Applications
- Embedded PC motherboard interconnects
- Industrial monitoring system backplanes
- Communication equipment signal routing
Procurement Notes
Verify the specific suffix code against official Harwin documentation to confirm contact plating and orientation details. Ensure the right-angle footprint matches the target PCB design constraints. Confirm RoHS compliance status via the manufacturer's current datasheet before finalizing procurement orders.
Selection Notes
Select this component when a high-density, single-row interface is required in a vertical orientation. The 2.54 mm pitch aligns with industry-standard pin headers. Consider the right-angle form factor for efficient stacking height reduction compared to straight connectors.
Part Context
This part belongs to the M20 series, which serves as a standard solution for board-to-board applications. The series offers various row counts and positions, widely adopted in consumer electronics and industrial control systems requiring robust, compact interconnects.
Replacement Considerations
Consult the official Harwin replacement guide for direct equivalents. Verify that any substitute maintains the 2.54 mm pitch, right-angle mounting style, and UL94 V-0 housing rating to ensure mechanical and thermal compatibility.
