M20-7832542

Overview

The M20-7832542 is a dual in-line vertical socket connector from the Harwin M20 series, designed for board-to-board or cable stacking applications. It features 50 positions arranged in two rows of 25 contacts with a 2.54 mm (0.1 inch) pitch. The housing dimensions are 2.516 inches in length, 0.335 inches in depth, and 0.198 inches in width. Electrical specifications include a contact resistance of 20 mΩ and an insulation resistance of 1,000,000,000 Ω. The contacts are made of phosphor bronze with gold mating surfaces and tin termination plating.

Feature Summary

• Vertical socket design facilitates direct board stacking or cable connections.
• Dual in-line configuration provides high-density connectivity with 50 positions.
• Phosphor bronze contacts ensure mechanical durability and stable electrical performance.
• Gold and tin plating offers corrosion resistance and reliable solderability.

Applications

• Board-to-board interconnections
• Cable stacking assemblies
• General industrial electronics

Procurement Notes

Verify component authenticity through authorized distributors or the manufacturer directly. Confirm RoHS compliance status and check for end-of-life notifications prior to procurement. Ensure storage conditions maintain integrity of the tin termination plating. Validate that the specific suffix matches the required vertical orientation and contact finish for the target application.

Selection Notes

Select this component when a vertical 50-position socket is required for dense PCB layouts. The 2.54 mm pitch ensures compatibility with standard header pins. Consider the 0.335-inch body depth for stack height constraints. Verify that the operating temperature range of -40°C to 105°C meets environmental requirements. Compare against other M20 variants if different row counts or orientations are needed.

Part Context

This part belongs to the Harwin M20 series, known for robust rectangular connectors. The M20 family includes various header and socket configurations with consistent 2.54 mm spacing. This specific model represents a vertical socket variant, distinct from surface mount or angled options within the same product line.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-reference with other M20 series sockets if pin count or orientation differs.
