M20-8770342R

Headers, Male Pins Overview

The M20-8770342R is a surface mount pin header from the Harwin M20 series, designed for board-to-board and wire-to-board connections. It features a single row with three positions and a 2.54 mm (0.100 inch) pitch. The connector utilizes brass contacts with gold plating on the mating interface and tin plating on the tail for soldering. Rated for 3 A current and 250 V voltage, it operates within a temperature range of -40°C to +105°C. The housing is made of black polyamide (PA6T) with UL94 V-0 flammability rating.

Headers, Male Pins Feature Summary

• Surface mount vertical design for automated PCB assembly
• Gold-plated square contacts ensure reliable signal transmission
• Polyamide insulation provides high thermal stability and flame resistance

Headers, Male Pins Applications

• Compact electronic modules requiring low-profile interconnects
• Consumer electronics with space-constrained layouts
• Industrial control boards needing robust surface-mount headers

Headers, Male Pins Procurement Notes

Verify the 'R' suffix indicates reel packaging when sourcing. Confirm RoHS compliance status against the latest manufacturer datasheet. Ensure compatibility with standard SMT reflow profiles. Check for any specific handling instructions regarding moisture sensitivity levels prior to assembly.

Headers, Male Pins Selection Notes

Select this component for applications requiring a single-row, unshrouded surface mount header. The 2.54 mm pitch suits general-purpose digital and power signals. Verify that the 3A rating meets circuit requirements. Consider the 11.53 mm stacking height for clearance constraints.

Headers, Male Pins Part Context

Part of the M20 family, known for high-density interconnect solutions. The M20-877 variant specifically denotes single-row configurations. This model complements matching socket assemblies for complete board-to-board connectivity systems in modern electronics manufacturing.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other 3-position, 2.54mm pitch SMT headers from manufacturers like Samtec or Molex, provided mechanical dimensions and electrical ratings match. Verify contact material and plating thickness for equivalent performance.
