M20-8770942P

Headers, Male Pins Overview

The M20-8770942P is a single-row surface mount header connector from the Harwin M20 series. It features 9 positions with a 2.54 mm (0.100 inch) pitch. The connector utilizes square male pins made of brass, plated with tin on the tail and gold on the mating interface. Designed for board-to-board or cable applications, it operates within a temperature range of -40°C to +105°C. The housing is constructed from black polyamide (PA6T), rated UL94 V-0 for flammability. It supports a rated current of 3A per contact and a voltage of 250V.

Headers, Male Pins Feature Summary

• Surface mount design with push-pull locking mechanism for secure attachment
• Cuttable construction allows for flexible pin count configuration
• Gold-plated mating contacts ensure reliable signal transmission
• High-temperature resistant PA6T insulation material

Headers, Male Pins Applications

• Board-to-board interconnections in compact electronic assemblies
• Cable-to-board connections requiring vertical orientation
• Industrial control systems operating in high-temperature environments
• Consumer electronics with space-constrained PCB layouts

Headers, Male Pins Procurement Notes

Verify the specific suffix 'P' against the manufacturer datasheet to confirm packaging details, as suffixes often denote reel or tube variations rather than functional changes. Ensure the component matches the required RoHS compliance status for your assembly process. Cross-reference the lead time with the distributor's current stock availability, as standard delivery periods may vary. Confirm that the tin-plated tails are compatible with your soldering profile and flux requirements.

Headers, Male Pins Selection Notes

Select this component when a single-row, vertical surface mount header is required for low-current signal applications. The 2.54 mm pitch ensures compatibility with standard DIP and SMT components. Consider the cuttable feature if variable pin counts are needed across different production runs. Verify that the 3A current rating and 250V voltage rating meet the circuit requirements. Ensure the PCB footprint accommodates the specified stacking heights and solder mask clearance.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 series, which offers a range of rectangular connectors designed for high-density applications. The M20 series is known for its robust mechanical performance and wide operating temperature range. Similar parts in the series include headers with varying pin counts and row configurations, such as the M20-8770942. The series supports both through-hole and surface mount technologies, providing flexibility for diverse manufacturing needs.

Headers, Male Pins Replacement Considerations

Direct substitutes include other Harwin M20 series headers with identical pitch and row configuration, such as M20-8770942. Verify that any replacement maintains the same contact plating, insulation material, and mounting style. Ensure the alternative part number matches the required pin count and electrical ratings. Consult the manufacturer's obsolescence notices to avoid selecting discontinued variants.
