M20-7833442

Overview

The Harwin M20-7833442 is a dual-in-line (DIL) vertical socket assembly designed for printed circuit board mounting. It features a 68-position configuration with a 2.54 mm pitch, arranged in two rows of 34 contacts each. The connector utilizes phosphor bronze contacts with gold plating to ensure reliable signal transmission and low contact resistance. The housing is constructed from polyamide (PA6T), rated UL94 V-0 for flame retardancy, providing mechanical stability and thermal resistance. This component supports through-hole termination methods.

Feature Summary

• Dual-in-line vertical orientation for compact board stacking
• Gold-plated phosphor bronze contacts for corrosion resistance
• UL94 V-0 rated polyamide insulation for thermal safety

Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment backplanes
• General-purpose electronic assemblies needing reliable signal routing

Procurement Notes

Verify the specific pin count and row configuration against design requirements before ordering. Confirm that the vertical tail length matches the available board clearance. Check for RoHS compliance documentation if environmental regulations apply to the final product. Ensure the mating header or cable assembly is compatible with the 2.54 mm DIL standard.

Selection Notes

Select this model when a vertical, dual-row female connector is required for through-hole PCB integration. Consider the 68-pin capacity for applications needing dense signal distribution. Evaluate the gold plating thickness if high-cycle mating durability is critical. Compare physical dimensions against adjacent components to prevent interference during assembly.

Part Context

This part belongs to the Harwin M20 series, which focuses on high-reliability rectangular connectors for demanding environments. The series offers various configurations including single and double row options with different termination styles. The M20-7833442 specifically addresses needs for vertical, high-pin-count connections in space-constrained designs.

Replacement Considerations

Direct substitutes within the same series include M20-7833242, which shares similar structural characteristics. Verify compatibility with existing tooling and mating parts before switching. Cross-reference pin layouts and electrical ratings to ensure functional equivalence in the target application.
