M20-8770942

Headers, Male Pins Overview

The M20-8770942 is a surface-mount header connector from the Harwin M20 series, featuring 18 positions in a single row with a 2.54 mm pitch. It utilizes square brass contacts with gold plating for mating and tin plating for termination, rated at 3A per contact and 250V. The housing is black polyamide (PA6T) with UL94 V-0 flammability rating. Designed for board-to-board or cable applications, it operates within a temperature range of -40°C to 105°C and includes pick-and-place compatibility.

Headers, Male Pins Procurement Notes

Verify the specific suffix '42' against official Harwin documentation to confirm contact plating specifications and material composition. Ensure that the selected variant matches the required thermal performance and mechanical retention standards for the target application environment. Cross-reference the datasheet for precise reflow soldering profiles and storage conditions to maintain component integrity during procurement and handling.

Headers, Male Pins Selection Notes

Select this component when a single-row surface-mount header with 2.54 mm pitch is required for high-reliability signal applications. Consider the 3A current rating and 250V voltage limit to ensure compliance with circuit requirements. Evaluate the need for pick-and-place compatibility if automated manufacturing is utilized. Confirm that the operating temperature range of -40°C to 105°C aligns with the environmental conditions of the end product.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 series, a family of rectangular connectors designed for space-constrained applications. The series offers various pin counts and configurations, including single and double rows, to support diverse board-to-board and cable-to-board interconnection needs. The M20-8770942 specifically addresses requirements for single-row surface-mount headers with standardized 2.54 mm spacing.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other M20 series headers such as M20-8770842 (8-position) or M20-8771042 (10-position) for different pin counts. For direct replacement, verify identical pitch, row count, and mounting style. Alternative manufacturers may offer generic equivalents, but mechanical dimensions and electrical ratings must be strictly matched.
