M80-5021842

Headers, Male Pins Overview

The M80-5021842 is a Datamate J-Tek male header connector manufactured by Harwin Inc. It features a vertical surface-mount design with 18 positions arranged in a dual inline configuration (9+9). The connector utilizes a 2.00mm pitch and incorporates jackscrew locking for secure attachment. Contact surfaces are gold-plated, while the posts are tin-plated phosphor bronze. The housing is constructed from black, glass-filled polyphenylene sulfide (PPS) rated UL94 V-0. It operates within a temperature range of -55°C to +125°C and supports mating stack heights of 7.3mm, 7.7mm, 9.75mm, 10.75mm, 13.35mm, and 14.75mm.

Headers, Male Pins Feature Summary

Headers, Male Pins Procurement Notes

Verify the specific suffix code to confirm the exact stacking height variant required for the application. Ensure the ordering part number matches the desired contact plating thickness and insulation material specifications. Cross-reference the official Harwin datasheet for the complete dimensional drawing and mating partner compatibility list before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when vertical SMT mounting is preferred over through-hole technology to save board space. The jackscrew feature is essential for applications where standard push-pull latches may fail under thermal cycling or shock. Confirm that the 2.00mm pitch aligns with the mating connector's footprint and that the selected stack height accommodates the mechanical envelope constraints of the enclosure.

Headers, Male Pins Part Context

This connector belongs to the Datamate J-Tek series, designed for high-reliability interconnects in harsh environments. The M80-5021842 specifically addresses the need for secure, vertically mounted headers in dense electronic assemblies. Its construction emphasizes durability and precise alignment through mechanical locking rather than friction alone.
