MSS2250R Equivalent & Substitute Parts

Part Overview

The MSS2250R is a slide switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a Double Pole Double Throw (DPDT) switch with a 300mA AC current rating at 125V. This component features through-hole, right-angle mounting with epoxy sealed terminals and is designed for applications requiring reliable switching with a 15,000-cycle mechanical and electrical life rating.

The MSS2250R is classified as an obsolete product. Locating equivalent or substitute components is necessary for ongoing maintenance, repair, and new design implementations where this legacy switch is specified or required as a direct replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSS2250R is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following areas:

Electrical Parameters: Circuit configuration (DPDT), contact timing (Shorting/MBB), switch function (On-On), current rating (300mA AC), and voltage rating (125V AC).

Mechanical Parameters: Mounting type (Through Hole, Right Angle), termination style (PC Pin), actuator length (9.50mm), switch travel (2.00mm), operating force (600gf), and actuator material (POM).

Environmental Parameters: Operating temperature range (-20°C to 85°C), contact material (Copper Alloy), and contact finish (Silver).

Life Ratings: Both mechanical life and electrical life must be rated for 15,000 cycles minimum.

The substitute part 1571630-2 meets all these criteria and is therefore classified as a direct equivalent to the MSS2250R.
