M80-8810542

Overview

The M80-8810542 is a Datamate L-Tek male header connector manufactured by Harwin Inc. It features a single row with five positions and a 2.00 mm pitch. The component utilizes through-hole right-angle termination for board mounting. Contacts are made of phosphor bronze with tin plating on the posts and gold plating on the mating surfaces, specifically 0.75 µm thick. The housing is black polyphenylene sulfide (PPS) reinforced with glass fiber, rated UL94 V-0. It operates within a temperature range of -55°C to +125°C, supporting a current rating of 2.2 A and voltage up to 800 V.

Feature Summary

• Four-wall shrouded design provides mechanical guidance during mating and protects contacts from environmental contamination.
• Friction latch mechanism ensures secure connection without additional locking hardware.
• Tin-plated contact posts offer cost-effective conductivity suitable for general applications.
• Gold-plated mating surfaces ensure reliable signal transmission and corrosion resistance.

Applications

• Industrial control systems requiring robust interconnects
• Power distribution boards in electronic assemblies
• Consumer electronics with space-constrained layouts
• Automotive subsystems needing vibration-resistant connections

Procurement Notes

Verify the specific lot code and manufacturing date against project requirements before procurement. Confirm that the tin-plated variant meets the environmental conditions of the target application, as gold-plated alternatives exist for harsher environments. Ensure compatibility with the corresponding female socket connectors within the Datamate L-Tek series to guarantee proper mating force and stacking height alignment.

Selection Notes

Select this part when a right-angle, single-row male header with friction latch is required. The tin-plated posts distinguish it from gold-plated variants, impacting cost and environmental suitability. Verify that the 2.00 mm pitch and 5-position count align with the PCB layout. Consider the operating temperature range and voltage rating to ensure compliance with system specifications.

Part Context

This component belongs to the Datamate L-Tek family, known for its compact size and high density. The M80-8810542 represents a standard male header configuration within this series. It is designed for board-to-board or cable-to-board connections, offering a balance between performance and manufacturability. The series supports various stacking heights and contact finishes to meet diverse engineering needs.

Replacement Considerations

M80-8520642 is listed as a potential replacement, though position count differs. Verify exact pin count and electrical ratings before substitution. No direct identical substitute is confirmed in public data; consult Harwin for cross-reference options if availability is an issue.
