M20-7851246

Overview

The M20-7851246 is a socket assembly header from the Harwin M20 series, designed for board-to-board applications. It features a dual in-line (DIL) configuration with 12+12 positions, totaling 24 contacts. The connector utilizes a 2.54 mm (0.1 inch) pitch and is constructed for surface-mount technology (SMT) termination. It employs bottom entry for mating access and includes tin plating on the contacts. The unit weight is specified as 1.896 g.

Feature Summary

• Dual row DIL socket assembly design for high-density PCB integration
• Surface mount termination compatible with standard SMT reflow processes
• Bottom entry orientation facilitates specific board stacking configurations

Applications

• Board-to-board interconnection systems
• High-density PCB mounting applications
• Industrial electronic assemblies requiring robust header connections

Procurement Notes

Verify component status prior to order placement, as this part number may be subject to end-of-life or discontinuation notices. Confirm current availability through authorized distributors, as stock levels fluctuate. Ensure that the tin plating specification meets the required environmental and corrosion resistance standards for the target application environment before finalizing procurement decisions.

Selection Notes

Select this component when a dual-row, surface-mount socket with bottom entry is required for 2.54 mm pitch applications. The M20 series offers compact dimensions suitable for space-constrained designs. Consider the tin contact finish for general-purpose use. Verify that the 24-position count aligns with circuit requirements and that the SMT package type matches the manufacturing process capabilities of the production line.

Part Context

This component belongs to the Harwin M20 series, which provides industrial-standard headers and wire housings. The series is characterized by its compact design, UL94V-0 rated high-temperature liquid crystal polymer housing, and durable double-beam contacts. These connectors are engineered to meet strict PCB density and height limitations while maintaining reliable electrical performance in demanding environments.

Replacement Considerations

Check official Harwin documentation for direct substitutes within the M20 series. Alternative options may include different position counts or plating finishes such as gold-tin combinations. Verify mechanical compatibility and pinout alignment before transitioning to any replacement part numbers.
