M50-4904945

Headers, Male Pins Overview

The Harwin M50-4904945 is a 1.27 mm pitch dual in-line surface-mount pin header assembly from the ARCHER series. It features 98 positions arranged in two rows with a straight mounting angle and solder termination. The contacts are gold-plated brass pins housed in a black liquid crystal polymer (LCP) shroud. Rated for 1 A current and 300 V voltage, it operates between -40°C and +105°C. The connector utilizes a push-pull fastening mechanism and meets UL 94 V-0 flammability standards.

Headers, Male Pins Feature Summary

• Dual row surface-mount architecture with 1.27 mm spacing
• Gold-plated brass contact system for reliable conductivity
• Black LCP housing with four-wall shrouding design
• Push-pull mechanical locking mechanism for secure mating

Headers, Male Pins Applications

• High-density board-to-board interconnections
• Compact electronic assemblies requiring surface-mount headers
• Industrial control systems with vertical stacking needs

Headers, Male Pins Procurement Notes

Verify the specific position count and packaging configuration against the official Harwin datasheet before ordering. Confirm that the gold plating thickness and material composition meet your application's durability requirements. Ensure the push-pull fastening style aligns with your assembly tooling capabilities. Check for any recent product change notices regarding material substitutions or manufacturing location changes.

Headers, Male Pins Selection Notes

Select this component when a high-pin-count, low-profile surface-mount solution is required. The 1.27 mm pitch allows for dense circuit layouts while maintaining adequate spacing. The gold finish ensures corrosion resistance in demanding environments. Consider the push-pull feature if repeated mating cycles or vibration resistance are critical to the design.

Headers, Male Pins Part Context

This part belongs to the Harwin ARCHER M50 series, designed for space-constrained applications. The series offers various pin counts and configurations, all sharing the same 1.27 mm pitch and robust construction. The M50-4904945 represents a high-density variant within this family, suitable for complex multi-layer board designs.

Headers, Male Pins Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Evaluate other ARCHER series headers with matching pitch and pin count if availability is an issue. Cross-reference with generic 1.27 mm SMT headers only if mechanical dimensions and electrical ratings are fully compatible.
