MSSA1350R Equivalent & Substitute Parts

Part Overview

The MSSA1350R is a slide switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a single-pole triple-throw (SP3T) switch with a 300mA AC current rating at 125V. This through-hole, right-angle mounted component features epoxy sealed terminals and is designed for On-On-On switching applications with shorting contact timing (MBB). The MSSA1350R is classified as obsolete, necessitating identification of active equivalent components to maintain design continuity and ensure ongoing component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete MSSA1350R with active equivalent components is determined by strict electrical and mechanical parameter matching. The primary substitute, part number 1825194-1, maintains functional equivalence through identical circuit configuration (SP3T), contact timing (Shorting MBB), current rating (300mA AC), voltage rating (125V AC), and switch function (On-On-On). Both components share the same contact material composition (Copper Alloy with Silver finish), operating temperature range (-20°C to 85°C), mechanical life (15,000 cycles), and electrical life (15,000 cycles). The termination style (PC Pin) and epoxy sealed terminal features remain consistent across both parts.

Substitution is valid based on the following key parameters:

• Identical SP3T circuit configuration
• Matching 300mA AC current rating
• Matching 125V AC voltage rating
• Identical contact timing (Shorting MBB)
• Identical switch function (On-On-On)
• Matching contact material and finish
• Identical operating temperature range
• Matching mechanical and electrical life ratings
• Identical termination style (PC Pin)

Parameter Comparison

Engineering Selection Recommendations

The MSSA1350R is classified as obsolete, making 1825194-1 the appropriate active substitute for new designs and ongoing production requirements. Both components are manufactured by TE Connectivity ALCOSWITCH Switches and share identical electrical specifications, ensuring functional compatibility in SP3T switching applications rated for 300mA AC at 125V.

The substitute part 1825194-1 carries active product status, ensuring continued availability and supply chain reliability. Both components maintain identical circuit configuration, contact timing, switch function, and operating parameters. The actuator length differs between the two parts (9.02mm versus 10.16mm), and the actuator material composition differs (Polyester versus Polyamide PA66/Nylon 6/6), with the substitute exhibiting a higher operating force (600gf versus 470gf). These mechanical variations do not affect electrical substitution validity but require verification of mechanical fit within the target application's physical constraints and actuator engagement requirements.

Both parts carry identical ECCN (EAR99) and HTSUS (8536.50.9050) classifications. RoHS compliance status differs between the parts; however, this distinction does not preclude substitution in applications where RoHS compliance is not mandated.

Frequently Asked Questions (FAQ)

Q: Can 1825194-1 directly replace MSSA1350R in all applications?

A: Electrical substitution is valid based on identical circuit configuration (SP3T), current rating (300mA AC), voltage rating (125V AC), contact timing (Shorting MBB), and switch function (On-On-On). Mechanical fit must be verified due to differences in actuator length (9.02mm versus 10.16mm) and mounting angle designation (right angle versus standard through-hole).

Q: What are the key differences between MSSA1350R and 1825194-1?

A: The primary differences are product status (obsolete versus active), actuator length (9.02mm versus 10.16mm), actuator material (Polyester versus Polyamide PA66/Nylon 6/6), and operating force (470gf versus 600gf). All electrical parameters remain identical.

Q: Does the difference in actuator material affect performance?

A: The actuator material change from Polyester to Polyamide (PA66/Nylon 6/6) does not affect electrical performance. Both materials are suitable for the specified operating temperature range (-20°C to 85°C) and mechanical life rating (15,000 cycles).

Q: Is the increased operating force (600gf versus 470gf) a concern?

A: The operating force increase from 470gf to 600gf represents a mechanical characteristic change. This affects actuator engagement effort but does not impact electrical functionality. Applications requiring specific actuation force characteristics should evaluate this parameter against design requirements.

Q: Are there packaging differences between these parts?

A: Both components are supplied in bulk packaging. Inventory availability differs, with MSSA1350R showing 849 pieces and 1825194-1 showing 766 pieces in current stock.

Q: What compliance certifications apply to both parts?

A: Both components carry identical ECCN (EAR99) and HTSUS (8536.50.9050) classifications. RoHS compliance status differs; MSSA1350R is non-compliant while 1825194-1 status is not applicable. REACH status is vendor undefined for both parts.
