MSSA2450 Equivalent & Substitute Parts

Part Overview

The MSSA2450 is a slide switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a DP4T (Double Pole Four Throw) through-hole component rated for 300mA AC at 125V. This switch features epoxy sealed terminals, silver-plated copper alloy contacts, and is designed for applications requiring multiple switching positions with shorting contact timing.

The MSSA2450 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production and maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSSA2450 is based on electrical and mechanical parameter equivalence within the TE Connectivity ALCOSWITCH Switches product family. The substitute part must maintain identical specifications across the following critical parameters:

• Circuit configuration (DP4T)
• Current and voltage ratings (300mA AC, 125V AC)
• Contact timing mechanism (Shorting/MBB)
• Switch function (On-On-On-On)
• Mounting and termination (Through Hole, PC Pin)
• Contact material and finish (Copper Alloy, Silver)
• Operating temperature range (-20°C to 85°C)
• Mechanical and electrical life (15,000 Cycles)
• Operating force (600gf)
• Switch travel (2.00mm)

The substitute part 1825200-1 meets all these criteria and is classified as an active product, providing improved supply availability compared to the obsolete MSSA2450.

Parameter Comparison

Engineering Selection Recommendations

The part 1825200-1 is a direct functional equivalent to the MSSA2450 and is recommended for new designs and ongoing production support. Both components are manufactured by TE Connectivity ALCOSWITCH Switches and share identical electrical ratings, circuit configuration, and mechanical specifications.

The MSSA2450 is classified as obsolete, while 1825200-1 maintains active product status with confirmed inventory availability (765 pieces in stock). Both parts carry ROHS3 compliance certification, meeting current environmental and regulatory requirements.

The actuator material differs between the two parts (polyester versus polyamide/nylon 6/6), but both materials provide equivalent mechanical performance within the specified operating temperature range of -20°C to 85°C. The actuator length variance of 0.04mm (10.41mm versus 10.37mm) is within standard manufacturing tolerances and does not affect functional compatibility in through-hole mounting applications.

Selection of 1825200-1 ensures supply chain continuity and compliance with current product lifecycle management practices.

Frequently Asked Questions (FAQ)

Q: Can the 1825200-1 be used as a direct replacement for the MSSA2450 in existing designs?

A: Yes. The 1825200-1 is electrically and mechanically equivalent to the MSSA2450. Both components share identical circuit configuration (DP4T), current and voltage ratings (300mA AC, 125V AC), contact timing (Shorting/MBB), mounting type (Through Hole), and termination style (PC Pin). The minor actuator length difference (0.04mm) and actuator material variation do not affect functional compatibility in through-hole PCB applications.

Q: What is the primary reason for substituting the MSSA2450?

A: The MSSA2450 carries an obsolete product status. The 1825200-1 is an active product from the same manufacturer with confirmed inventory availability, ensuring reliable supply for production and maintenance requirements.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the MSSA2450 and 1825200-1 are ROHS3 compliant. Both carry identical ECCN (EAR99) and HTSUS (8536.50.9050) classifications.

Q: What is the difference in actuator material between these parts?

A: The MSSA2450 uses polyester actuator material, while the 1825200-1 uses polyamide (PA66/Nylon 6/6). Both materials operate within the specified temperature range of -20°C to 85°C and provide equivalent mechanical performance for this switch application.

Q: Are the packaging formats different?

A: The MSSA2450 is supplied with unspecified packaging, while the 1825200-1 is supplied in bulk packaging. Both formats are suitable for through-hole component assembly and integration into production workflows.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by matching the following electrical parameters: circuit configuration (DP4T), current rating (300mA AC), voltage rating (125V AC), contact timing (Shorting/MBB), and switch function (On-On-On-On). The 1825200-1 matches all these specifications.

Q: Are the mechanical life and electrical life ratings identical?

A: Yes. Both the MSSA2450 and 1825200-1 are rated for 15,000 mechanical cycles and 15,000 electrical cycles, with an operating force of 600gf and switch travel of 2.00mm.
