Overview
The M20-7910342R is a PCB receptacle from the Harwin M20 series, designed for board-to-board connections. It features a 2.54 mm pitch with one row and three contacts. The component utilizes surface mount technology for secure attachment to printed circuit boards. Contacts are gold-plated phosphor bronze, ensuring reliable conductivity. The housing is constructed from polyamide (PA9T), nylon 9T, or glass-filled variants. It supports a current rating of 3A and operates within standard industrial temperature ranges.
Feature Summary
- Gold-plated phosphor bronze contacts provide durable electrical connectivity.
- Polyamide insulation material offers thermal stability and mechanical strength.
- Surface mount design facilitates automated assembly processes.
Applications
- General purpose board-to-board interconnections
- Electronic device internal signal routing
- Industrial control module interfaces
Procurement Notes
Verify that the specific order matches the M20-7910342R designation exactly. Confirm RoHS compliance status and contact plating specifications against the latest manufacturer datasheet. Ensure storage conditions maintain integrity of the gold-plated contacts and polymer housing before installation.
Selection Notes
Select this component when a low-profile, single-row surface mount connector is required. The 2.54 mm pitch aligns with standard PCB footprints. Consider the 3A current rating and PA9T insulation properties for environmental compatibility. Verify that the board-to-board application does not require shrouded or keyed configurations found in other M20 variants.
Part Context
This part belongs to the Harwin M20 range, which specializes in 2.54 mm pitch connectors. The M20 series includes various header and receptacle options for different mounting styles. The M20-7910342R specifically addresses needs for compact, high-density board-to-board linking without requiring through-hole processing.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching pitch, contact count, and mounting type precisely.
