Overview
The Harwin M20-7811545 is a 30-position female receptacle connector from the M20 series, designed for surface mount applications. It features a 2.54 mm (0.1 in) pitch and utilizes gold-plated contacts to ensure reliable signal transmission. The housing is constructed from high-temperature nylon rated UL 94V-0, providing robust thermal stability. This component supports bottom or top entry configurations, offering flexibility in PCB layout design while maintaining secure mechanical connections.
Feature Summary
- Features a high-temperature UL 94V-0 nylon housing for enhanced thermal resistance.
- Utilizes copper alloy contacts with gold plating for superior conductivity and corrosion resistance.
- Supports both bottom and top entry orientations for versatile board integration.
Applications
- Surface mount interconnections in electronic assemblies
- Board-to-board connectivity requiring high reliability
- High-temperature circuit environments
Procurement Notes
Verify the specific contact configuration and entry orientation against the official datasheet before procurement. Confirm that the surface mount footprint matches the target PCB design. Ensure compliance with RoHS directives if required by the application environment. Cross-reference the manufacturer's latest documentation to confirm current availability status.
Selection Notes
Select this component when a 30-position surface mount female header is required. Consider the 2.54 mm pitch compatibility with mating pins. Evaluate the need for bottom versus top entry based on spatial constraints. Assess the thermal requirements against the UL 94V-0 rating of the housing material.
Part Context
This part belongs to the Harwin M20 series, which offers various row counts and mounting styles. The M20-7811545 specifically addresses the need for high-density, surface-mounted female connectors. It complements other M20 variants by providing a specialized 30-position option with gold plating for demanding applications.
Replacement Considerations
Consult the official Harwin obsolescence notices for confirmed substitute part numbers. Verify dimensional and electrical compatibility with any potential replacements. Ensure that alternative components maintain the same pitch and contact plating specifications.
