MSS1400 Equivalent & Substitute Parts

Part Overview

The MSS1400 is a slide switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a single-pole four-throw (SP4T) switch rated for 300mA at 125V AC. This through-hole mounted component features a standard actuator with 3.50mm length, copper alloy contacts with silver finish, and is sealed with epoxy-coated terminals. The MSS1400 operates across a temperature range of -20°C to 85°C with a mechanical and electrical life rating of 15,000 cycles.

The MSS1400 is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing maintenance, repair, and production requirements for legacy systems utilizing this switch configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSS1400 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications in the following critical areas:

Electrical Parameters: Circuit configuration (SP4T), current rating (300mA AC), voltage rating (125V AC), contact timing (Shorting/MBB), and switch function (On-On-On-On).

Mechanical Parameters: Mounting type (Through Hole), termination style (PC Pin), actuator type (Standard), actuator length (3.50mm), switch travel (2.00mm), and operating force (600gf).

Material and Environmental Parameters: Contact material (Copper Alloy), contact finish (Silver), operating temperature range (-20°C to 85°C), mechanical life (15,000 cycles), electrical life (15,000 cycles), and epoxy sealed terminals.

The substitute part 1571423-2 meets all these criteria and is therefore a direct functional equivalent to the MSS1400.

Parameter Comparison

Engineering Selection Recommendations

The part 1571423-2 is a direct substitute for the MSS1400 based on complete electrical and mechanical parameter equivalence. All functional specifications, including circuit configuration, current and voltage ratings, actuator dimensions, contact materials, and lifecycle ratings, are identical between the two components.

The primary distinction between these parts is product status and compliance certification. The MSS1400 is classified as obsolete, while 1571423-2 is an active product. The 1571423-2 carries ROHS3 compliance certification, indicating conformance to current environmental and material restriction standards. This compliance status makes 1571423-2 the preferred selection for new designs and ongoing production support.

Both components are manufactured by TE Connectivity ALCOSWITCH Switches within the MSS series and share identical through-hole mounting and PC pin termination characteristics, ensuring direct mechanical and electrical compatibility in existing circuit board layouts.
