929665-02-20-EU

Headers, Male Pins Overview

The 3M 929665-02-20-EU is a vertical male pin header connector from the 929 series, designed for through-hole PCB mounting. It features a 2.54mm (0.100 inch) pitch with 20 positions arranged in a single row. The contacts are gold-plated copper alloy pins with a mating contact length of 0.235 inches and a post contact length of 0.210 inches. The insulator is made of black PCT material rated UL94 V-0, supporting an operating temperature range of -40°C to 105°C. This component utilizes a push-pull locking mechanism and is suitable for board-to-board applications.

• Push-pull locking style for stable connection retention
• High-temperature PCT insulation compatible with wave soldering processes

Headers, Male Pins Applications

• Board-to-board interconnections
• Line-to-board connections
• Industrial automation systems
• Data center hardware design

Headers, Male Pins Procurement Notes

Verify the specific suffix 'EU' against manufacturer documentation to confirm compliance requirements and plating specifications. Confirm availability status as distribution channels may list discontinued or obsolete inventory. Ensure the selected variant matches the required pin count and row configuration for the target PCB footprint. Cross-reference the DigiKey part number 3M156317-ND for accurate sourcing details.

Headers, Male Pins Selection Notes

Select this connector when a vertical, single-row header with gold plating is required for high-reliability applications. The 2.54mm pitch allows compatibility with standard breadboards and prototyping setups. Consider the thermal resistance of the PCT material if wave soldering is part of the manufacturing process. Evaluate the push-pull locking feature against other retention methods like snap-on or screw-lock mechanisms based on vibration requirements.

Headers, Male Pins Part Context

This component belongs to the 3M 929 series of pin headers, which offer versatile design flexibility through stackable and breakaway options. The series provides both horizontal and vertical versions in various pin counts and contact finishes. These connectors are engineered to support diverse electronic assembly needs, ranging from simple prototyping to complex industrial equipment, emphasizing durability and electrical performance.

Headers, Male Pins Replacement Considerations

Direct substitutes within the same series include variants with different pin counts such as 929665-02-18-EU or 929665-02-22-EU. Alternative manufacturers offering 2.54mm pitch vertical headers should be evaluated for mechanical fit and electrical ratings. Verify that any replacement maintains the same contact material, plating thickness, and insulation flammability rating to ensure functional equivalence.
