TXD2SS-12V Equivalent & Substitute Parts

Part Overview

The TXD2SS-12V is a general purpose relay manufactured by Panasonic Electric Works, featuring DPDT (2 Form C) contact configuration with 2A contact rating and 12VDC coil voltage. This surface mount relay is designed for applications requiring sealed, fully enclosed switching functionality across industrial and commercial control circuits. The part is currently active in production with full RoHS compliance, ensuring continued availability and regulatory alignment for new designs.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the same relay series, allowing for design flexibility, inventory optimization, and supply chain continuity.
