AW140-EG-G04A1

Overview

The AW140-EG-G04A1 is a single-row pin header connector from the AW140 series, manufactured by Assmann WSW Components. Designed for board-to-board applications, this component features a 2.54 mm pitch and contains four contacts. It utilizes brass terminals with gold plating housed in a polybutylene terephthalate (PBT) insulator. The connector supports through-hole mounting with solder termination and operates within a temperature range of -40°C to +105°C. Rated for 3A current and 250V voltage, it provides reliable electrical interconnection for standard PCB layouts.

Feature Summary

• Single-row straight pin header configuration for direct vertical board stacking
• Gold-plated brass contacts ensure stable signal transmission and corrosion resistance
• Polybutylene terephthalate housing offers thermal stability and mechanical durability
• Through-hole solder termination ensures secure attachment to printed circuit boards

Applications

• Board-to-board interconnections in compact electronic modules
• Signal routing between stacked printed circuit boards
• General-purpose connections in consumer electronics assemblies
• Industrial control unit interface points requiring robust through-hole mounting

Procurement Notes

Verify the specific part number AW140-EG-G04A1 against official manufacturer documentation to confirm contact count and orientation. Ensure compatibility with mating socket components regarding pitch and housing dimensions. Cross-reference terminal specifications to validate current and voltage ratings for the intended application environment before finalizing procurement decisions.

Selection Notes

Select this component when a low-profile, single-row connection is required for vertical board stacking. The 2.54 mm pitch aligns with standard PCB grid systems, facilitating easy integration into existing designs. Consider the through-hole mounting requirement and soldering process capabilities during the design phase to ensure proper mechanical fixation and electrical continuity.

Part Context

This connector belongs to the AW140 series, which provides a range of single-row pin headers for various board-to-board applications. The series is characterized by its standardized 2.54 mm pitch and durable PBT construction. The AW140-EG-G04A1 specifically denotes a four-position variant, offering a compact solution for limited-space interconnect needs while maintaining the series' general performance standards.

Replacement Considerations

Direct substitutes include other AW140 series variants with matching 2.54 mm pitch and single-row configuration, such as AW140-EG-G06A or AW140-EG-G08A, provided the contact count difference is acceptable. Ensure any replacement maintains the same through-hole mounting style and gold-plated brass terminal specifications for equivalent electrical performance.
