MSS1200RG Equivalent & Substitute Parts

Part Overview

The MSS1200RG is a slide switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a Single Pole Double Throw (SPDT) switch with a rated capacity of 0.4VA at 20V. This component features a through-hole, right-angle mounting configuration with gold-plated copper alloy contacts and polyoxymethylene actuator material. The MSS1200RG is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production requirements. Substitute parts must maintain identical electrical ratings, mechanical specifications, and physical form factors to ensure direct compatibility in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSS1200RG is determined by strict equivalence across all electrical and mechanical parameters. The substitute part 1825258-2 qualifies as a direct equivalent based on the following criteria:

Electrical Equivalence: Identical SPDT circuit configuration, contact timing (Shorting MBB), switch function (On-On), current rating (0.4VA AC/DC), and voltage ratings (20V AC and DC).

Mechanical Equivalence: Matching actuator type (Standard), actuator length (4.00mm), contact material (Copper Alloy), contact finish (Gold), mounting type (Through Hole, Right Angle), and termination style (PC Pin).

Environmental Equivalence: Identical operating temperature range (-20°C to 85°C), switch travel (2.00mm), mechanical life (15,000 cycles), electrical life (15,000 cycles), and operating force (600gf).

Series Compatibility: Both components belong to the MSS series family, confirming design lineage and functional compatibility.

The primary distinction between the main part and substitute is product status: MSS1200RG is obsolete, while 1825258-2 is active production, making 1825258-2 the recommended selection for new applications.

Parameter Comparison
