Product details

Three-position header with latch holder for vibration-prone assemblies

The 2-171825-3 is a 3-position, single-row header from TE's EI series, pitched at 0.098" (2.50mm). The shrouded - 1 wall design and latch holder fastening keep the mated connector locked under vibration, making it a reliable choice for wire-to-board connections in industrial or automotive environments.

Current and voltage ratings for signal and low-power delivery

Each contact is rated 2 A, and the header handles up to 250 VAC or 350 VDC. The tin-plated mating surface (31.5 µin) suits moderate mating-cycle applications, while the brass contacts and PA66 housing (UL94 V-0) provide a cost-effective, flame-rated interconnect for general-purpose use.

Frequently asked questions

What is the mating connector for 2-171825-3?

This header mates with a matching EI-series receptacle housing (same pitch, single row) and the corresponding crimp terminal. The latch holder on the header engages with the housing's latch to secure the connection.
