M20-7821646

Overview

The M20-7821646 is a single-row PCB receptacle connector from the Harwin M20 series. It features 16 positions with a 2.54 mm (0.100 inch) pitch. Designed for through-hole mounting, this female header utilizes tin-plated contacts to ensure reliable signal transmission. The component supports a current rating of 3A and a voltage rating of 1000V. It is constructed with polyamide insulation material, providing durability for general purpose, industrial, and telecommunications applications.

Feature Summary

• Single-row female receptacle design for board-to-board connections
• Through-hole termination method for secure PCB attachment
• Tin-plated contact surfaces for corrosion resistance
• Polyamide insulation housing for thermal stability

Applications

• General purpose electronic assemblies
• Industrial control systems
• Telecommunications equipment

Procurement Notes

Verify the specific pin count and row configuration against the schematic requirements before procurement. Confirm that the through-hole mounting style aligns with the target PCB layout and manufacturing capabilities. Ensure the 3A current and 1000V voltage ratings meet the operational safety standards of the intended application environment.

Selection Notes

Select this component when a single-row, low-profile connection is required for high-voltage isolation up to 1000V. The 2.54 mm pitch offers standard spacing compatibility with common PCB footprints. Consider the tin plating for environments where solderability and basic corrosion protection are prioritized over gold performance.

Part Context

This part belongs to the M20 series, which provides industrial-standard headers and sockets. The series is known for compact designs suitable for dense PCB layouts. The M20-7821646 specifically represents the single-row variant, distinguishing it from the double-row options available within the same product family.
