M20-9961945

Headers, Male Pins Overview

The Harwin M20-9961945 is a right-angle pin header connector from the M20 series, designed for through-hole mounting. It features 19 positions with a 2.54mm pitch and single-row configuration. The contacts are gold-plated brass pins suitable for board-to-board or cable applications. Rated for 3A per contact, it operates within a temperature range of -40°C to 105°C. The housing is black polyamide (PA6T) with UL94 V-0 flammability rating.

Headers, Male Pins Feature Summary

• Right-angle design facilitates compact board layouts
• Gold-plated contacts ensure reliable signal transmission
• Cuttable construction allows for flexible circuit board sizing

Headers, Male Pins Applications

• Board-to-board interconnections
• Cable-to-board connections
• General electronic equipment internal wiring

Headers, Male Pins Procurement Notes

Verify the specific suffix '45' corresponds to the required gold plating and high-temperature soldering characteristics as defined in the official datasheet. Confirm that the right-angle orientation matches the mechanical constraints of the target assembly. Ensure compatibility with mating female connectors from the same M20 series family to guarantee proper engagement and electrical performance.

Headers, Male Pins Selection Notes

Select this component when a right-angle, single-row header is required for space-constrained designs. The 2.54mm pitch is standard for general-purpose electronics. Consider the 3A current rating and 105°C operating temperature limit against system requirements. The cuttable feature offers inventory flexibility compared to fixed-length variants.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 series, known for robust rectangular connectors. The M20-996xx45 numbering convention typically indicates a right-angle, single-row pin header with gold plating. It complements other M20 variants like straight headers and socket connectors, providing a complete interconnection solution for various industrial and consumer applications.

Headers, Male Pins Replacement Considerations

Direct substitutes include other Harwin M20 series right-angle headers with identical 19-position count and 2.54mm pitch, such as M20-9961845 or M20-9962045, depending on row length needs. Cross-brand replacements must match the 2.54mm pitch, right-angle form factor, and through-hole termination style to ensure mechanical fit.
