AW140-EG-G34B

Overview

The AW140-EG-G34B is a single-row male board-to-board connector header from the AW140 series by ASSMANN WSW. It features 34 contacts with a 2.54 mm (0.1 inch) pitch and utilizes gold-plated brass terminals for reliable signal transmission. Designed for through-hole soldering, this straight-mount component operates within a temperature range of -40°C to +105°C and supports up to 250V and 3A per contact. The housing is constructed from polybutylene terephthalate (PBT), providing mechanical stability and thermal resistance for standard PCB assembly applications.

Feature Summary

• Straight male pin header configuration designed for direct vertical mounting on printed circuit boards.
• Gold-plated brass contacts ensure low contact resistance and corrosion resistance for signal integrity.
• Polybutylene terephthalate (PBT) insulator provides high thermal stability and mechanical strength.
• Through-hole solder termination allows for secure attachment to standard PCB layouts.

Applications

• Interconnecting daughterboards to motherboards in modular electronic systems
• Signal routing in industrial control panels requiring robust board-to-board connections
• Consumer electronics assemblies utilizing standard 2.54mm pitch interfaces

Procurement Notes

Verify the specific suffix code against official manufacturer documentation to confirm terminal length and mating pin compatibility. Ensure the selected variant matches the required PCB thickness and locking mechanism specifications. Cross-reference the part number with authorized distributors to confirm current availability and compliance with RoHS directives before finalizing procurement orders.

Selection Notes

Select this component when a 34-position male header is required for rigid board-to-board interconnects. Consider the straight orientation and through-hole mounting method for standard assembly processes. Evaluate the 2.54mm pitch requirement against existing footprint constraints. Confirm that the 3A current rating and 250V voltage limit meet the electrical design requirements of the target application circuit.

Part Context

This part belongs to the AW140 series, which offers various contact counts and tail lengths to accommodate different PCB stack-up heights. The AW140 line is characterized by its standardized 2.54mm pitch and durable PBT construction. Variants within this series differ primarily in physical dimensions and terminal configurations while maintaining consistent electrical performance standards across the family.

Replacement Considerations

Compatible substitutes include other 34-position, 2.54mm pitch male headers from manufacturers such as Molex or Samtec, provided the mechanical footprint and locking features match. Verify that alternative parts support the same current and voltage ratings. Ensure the replacement maintains the through-hole solder termination type for compatible assembly equipment.
