MSS225R Equivalent & Substitute Parts

Part Overview

The MSS225R is a slide switch manufactured by APEM Inc., classified as a DPDT (Double Pole Double Throw) switch rated for 300mA at 125V AC and 30V DC. This through-hole, right-angle mounted component features epoxy sealed terminals and is designed for On-On switching applications. The MSS225R is currently listed as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance, repair, and new design implementations where legacy component compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSS225R is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: DPDT topology must be maintained
• Switch Function: On-On operation required
• Current Rating: Minimum 300mA capability at rated voltage
• Voltage Rating - AC: Minimum 125V AC rating
• Voltage Rating - DC: Minimum 30V DC rating
• Mounting Type: Through Hole, Right Angle configuration
• Termination Style: PC Pin termination
• Actuator Length: 9.50mm standard
• Switch Travel: 2.00mm
• Contact Finish: Silver plating
• Features: Epoxy Sealed Terminals

The substitute part 1571630-2 manufactured by TE Connectivity ALCOSWITCH Switches meets all critical electrical and mechanical parameters required for direct substitution. This part maintains identical circuit topology, voltage and current ratings, physical mounting characteristics, and terminal configuration. The substitute is currently in active production status, ensuring availability for replacement and new applications.

Parameter Comparison

Engineering Selection Recommendations

The 1571630-2 from TE Connectivity ALCOSWITCH Switches is a direct functional equivalent to the obsolete MSS225R. Both components are ROHS3 compliant and meet identical electrical specifications for AC voltage operation at 125V and 300mA current capacity. The substitute part is currently in active production status, ensuring supply chain continuity and availability for both replacement applications and new designs.

The 1571630-2 demonstrates enhanced performance characteristics in operating temperature range (-20°C to 85°C versus -10°C to 60°C) and electrical life rating (15,000 cycles versus 10,000 cycles), providing additional margin for demanding applications. Physical compatibility is confirmed through identical mounting configuration, actuator dimensions, and PC pin termination.

Selection of the 1571630-2 is appropriate for all applications previously served by the MSS225R where DPDT On-On switching at 125V AC and 300mA is required in through-hole, right-angle mounted configurations.

Frequently Asked Questions (FAQ)

Q: Can the 1571630-2 be used as a direct replacement for the MSS225R in existing PCB designs?

A: Yes. The 1571630-2 maintains identical mounting type (through-hole, right-angle), actuator length (9.50mm), switch travel (2.00mm), and PC pin termination. No PCB layout modifications are required.

Q: Are there electrical performance differences between these parts?

A: Both parts are rated for 300mA at 125V AC operation. The 1571630-2 specifies AC current rating while the MSS225R specifies AC/DC. The 1571630-2 provides extended operating temperature range and higher electrical life cycle rating, representing performance enhancement rather than limitation.

Q: What is the significance of the contact timing specification difference?

A: The MSS225R lists contact timing as "Not Specified" while the 1571630-2 specifies "Shorting (MBB)" contact timing. MBB (Make-Before-Break) timing ensures continuity during switching transitions, which is standard for DPDT On-On switches and does not affect substitution compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both the MSS225R and 1571630-2 are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What packaging options are available for the 1571630-2?

A: The 1571630-2 is supplied in bulk packaging. Verify packaging requirements for your specific procurement and assembly processes.

Q: Why is the MSS225R listed as obsolete?

A: Obsolescence typically results from manufacturer discontinuation decisions. The 1571630-2 from TE Connectivity represents the active production equivalent, ensuring continued availability for applications requiring DPDT 300mA 125V slide switches with through-hole right-angle mounting.
