Overview
The Harwin M20-7823842 is a rectangular connector receptacle from the M20 series, designed for board-to-board or cable applications. It features 38 positions with a 0.100 inch (2.54 mm) pitch and two rows of female socket contacts. The component utilizes gold-plated phosphor bronze terminals and a black polyamide insulation housing rated UL94 V-0. It supports a current rating of 3A and operates within a temperature range of -40°C to 105°C.
Feature Summary
- Features a push-pull locking mechanism for secure mating retention
- Constructed with gold-plated phosphor bronze contacts for reliable conductivity
- Utilizes black polyamide (PA6T) insulation housing with UL94 V-0 flammability rating
Applications
- Board-to-board interconnections
- Cable-to-board connections
- General purpose industrial electronics
Procurement Notes
Verify the specific ordering suffix against the official Harwin datasheet to ensure correct contact plating and termination style. Confirm that the 38-position configuration matches the design requirements. Check for RoHS compliance status in the latest documentation. Ensure the package type aligns with assembly capabilities. Validate the component status as active or obsolete before finalizing procurement plans.
Selection Notes
Select this component when a 38-position female receptacle with a 2.54mm pitch is required. Consider the gold plating for corrosion resistance and low contact resistance. Evaluate the push-pull locking feature for vibration resistance needs. Verify the operating temperature range meets environmental constraints. Ensure the physical dimensions fit the available PCB space.
Part Context
This part belongs to the Harwin M20 series of rectangular connectors. The series offers various configurations including headers, sockets, and wire housings. The M20-7823842 specifically provides a high-density solution for vertical PCB mounting. It complements other M20 series components for complete system integration.
Replacement Considerations
No direct public substitute part numbers are confirmed for this specific model. Cross-reference with other Harwin M20 series female receptacles if pin count or pitch differs. Consult manufacturer documentation for potential end-of-life alternatives.
