M80-5104242

Headers, Male Pins Overview

The M80-5104242 is a Datamate J-Tek series pin header manufactured by Harwin Inc. It features a 42-position configuration arranged in two rows with a 2 mm (0.079 inch) contact pitch. Designed for through-hole termination, this connector utilizes male pins constructed from phosphor bronze with gold plating on the mating interface. The housing is made of black polyphenylene sulfide (PPS) reinforced with glass fiber, rated UL94 V-0 for flammability. It operates within a temperature range of -55°C to +125°C and supports up to 3 A current.

Headers, Male Pins Procurement Notes

Verify the specific suffix codes against the official Harwin datasheet to confirm exact tail length and keying options. Ensure the procurement matches the required contact count and termination style. Cross-reference the component marking with the manufacturer's latest revision history to avoid obsolete variants. Confirm RoHS compliance status if required by project specifications.

Headers, Male Pins Selection Notes

Select this model when high contact density and rugged environmental resistance are required. The 2 mm pitch balances space efficiency with electrical isolation. Verify that the application voltage does not exceed the series rating. Consider the shrouded design for preventing misalignment during mating. Ensure PCB layout accommodates the through-hole pad size and row spacing.
