M40-3010246R

Headers, Male Pins Overview

The Harwin M40-3010246R is a surface mount pin header from the M40 series, designed for wire-to-board connections. It features a 1 mm pitch and two positions in a single row configuration. The component utilizes a straight orientation with a shrouded tab design to ensure proper alignment during assembly. Electrical ratings include a current capacity of 1 A and a voltage rating of 50 V ac/dc. The contacts are constructed from phosphor bronze with tin plating over a nickel barrier. The housing material is specified as PBT, providing thermal stability. The unit weighs approximately 79 mg.

Headers, Male Pins Feature Summary

• Shrouded tab design ensures precise alignment and prevents misinsertion during surface mount assembly.
• Single-row configuration supports compact board layouts while maintaining reliable electrical connectivity.
• Tin-plated phosphor bronze contacts offer corrosion resistance and stable signal transmission.

Headers, Male Pins Applications

• Wire-to-board interconnections in compact electronic assemblies
• Surface mount integration for consumer electronics
• Board-to-cable connections requiring high-density routing

Headers, Male Pins Procurement Notes

Verify that the ordering suffix matches the required reel or cut tape packaging format. Confirm compliance with RoHS directives and lead-free requirements before procurement. Ensure the supplier provides valid traceability documentation for the specific manufacturing batch. Cross-reference the part number against the official Harwin catalog to avoid substitution errors. Validate that the received components match the specified 1 mm pitch and 2-position layout.

Headers, Male Pins Selection Notes

Select this component when a low-profile, surface-mount solution is required for small form-factor designs. The 1 mm pitch allows for dense circuit board arrangements compared to standard 2.54 mm headers. The shrouded design is suitable for applications where manual insertion accuracy is limited. Consider the 1 A current rating for power distribution needs within these limits. Evaluate the SMT mounting style against available reflow soldering capabilities on the production line.

Headers, Male Pins Part Context

This part belongs to the Harwin M40 series, which focuses on high-density interconnect solutions. The series offers various configurations including different pin counts and orientations. The M40-3010246R specifically addresses the need for reliable, space-saving connections in modern electronics. It complements other M40 variants by providing a standardized interface for board-to-wire applications.

Headers, Male Pins Replacement Considerations

Direct substitutes within the same series include M40-3010246 (non-reel version) and M40-3010246H. Verify compatibility with mating connectors from the same manufacturer family. Ensure any alternative maintains the 1 mm pitch and shrouded tab characteristics for mechanical fit.
