Overview
The Harwin M20-7821546 is a rectangular connector receptacle featuring 15 positions with a 2.54 mm pitch. It utilizes a single row of female sockets designed for through-hole PCB mounting. The contacts are tin-plated phosphor bronze, housed in black polyamide (PA6T) insulation rated UL94 V-0. Rated for 3A current and 1000V voltage, it operates within a temperature range of -40°C to 105°C. The assembly includes a carrier comb configuration.
Feature Summary
- Vertical board-to-board or cable stacking interface design
- Tin-plated contact finish for reliable signal transmission
- Polyamide insulation material providing high thermal stability
Applications
- General purpose electronic interconnections
- Industrial control systems
- Telecommunications equipment
Procurement Notes
Verify the specific pin count and row configuration against the official datasheet before procurement, as variations exist within the M20 series. Confirm that the tin-plated contact finish meets the environmental requirements for the intended application. Ensure the through-hole mounting style aligns with the target PCB layout specifications.
Selection Notes
Select this component when a single-row, vertical female socket is required for low-profile connections. The 2.54 mm pitch ensures compatibility with standard header pins. Consider the tin plating for general use rather than high-wear environments where gold might be preferred. Verify the height above board constraints fit the mechanical enclosure design.
Part Context
This part belongs to the Harwin M20 series of headers and wire housings. The series offers various configurations including different pin counts, row arrangements, and contact finishes. The M20-7821546 specifically represents a 15-position variant optimized for vertical mounting applications in compact electronic assemblies.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Cross-reference with other Harwin M20 series variants if exact specifications differ. Consult manufacturer resources for potential obsolescence management strategies.
