MSS225RG Equivalent & Substitute Parts

Part Overview

The MSS225RG is a slide switch manufactured by APEM Inc., configured as a DPDT (Double Pole Double Throw) through-hole component with right-angle mounting. This switch is rated for 0.4VA at 20V AC/DC and features gold-plated contacts with epoxy-sealed terminals. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing maintenance, repair, and redesign applications where this component is specified in existing designs.

Key Parameters

Substitute Part Grouping Explanation

The TE Connectivity ALCOSWITCH Switches part number 1571630-2 qualifies as a substitute for the MSS225RG based on the following critical parameters:

Matching Parameters:

• Circuit configuration: DPDT
• Switch function: On-On
• Mounting type: Through Hole, Right Angle
• Actuator length: 9.50mm
• Switch travel: 2.00mm
• Termination style: PC Pin
• Features: Epoxy Sealed Terminals
• RoHS3 Compliance

Electrical Compatibility Considerations: The 1571630-2 operates at higher voltage (125V AC) and current (300mA AC) ratings compared to the MSS225RG (20V, 0.4VA). This means the substitute part can safely operate in applications designed for the original part, as it exceeds the electrical specifications. The substitute is suitable for low-voltage, low-current applications where the MSS225RG was originally specified.

Mechanical Compatibility: Both switches share identical mechanical dimensions and mounting characteristics, ensuring direct PCB footprint compatibility without layout modifications.

Parameter Comparison

Engineering Selection Recommendations

The 1571630-2 is the designated substitute for the obsolete MSS225RG. Selection of this substitute is supported by:

Product Status: The 1571630-2 is an active product from TE Connectivity, ensuring ongoing availability and supply chain continuity compared to the obsolete MSS225RG.

Regulatory Compliance: Both parts maintain ROHS3 compliance, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Electrical Margin: The substitute part's higher voltage and current ratings (125V AC, 300mA) provide operational margin above the original specification (20V, 0.4VA), ensuring safe operation in the original application context.

Mechanical Compatibility: Identical actuator dimensions (9.50mm length) and switch travel (2.00mm) guarantee direct mechanical substitution without PCB redesign or mechanical rework.

Operational Life: The substitute offers extended electrical life (15,000 cycles versus 10,000 cycles), providing improved reliability in cyclic switching applications.

Frequently Asked Questions (FAQ)

Q: Can the 1571630-2 be used as a direct replacement for the MSS225RG without PCB modifications?

A: Yes. Both switches share identical mounting type (Through Hole, Right Angle), actuator length (9.50mm), and switch travel (2.00mm), enabling direct PCB footprint compatibility without layout changes.

Q: What are the key electrical differences between these parts?

A: The 1571630-2 is rated for 125V AC and 300mA, while the MSS225RG is rated for 20V AC/DC and 0.4VA. The substitute's higher ratings mean it can safely operate in applications designed for the original part's lower specifications.

Q: Are there any contact material differences that affect performance?

A: The MSS225RG uses gold-plated contacts, while the 1571630-2 uses silver-plated contacts. Both finishes are suitable for low-voltage switching applications. Contact material selection should be verified against specific application requirements regarding corrosion resistance and contact resistance.

Q: What is the operating temperature range difference?

A: The MSS225RG operates from -10°C to 60°C, while the 1571630-2 operates from -20°C to 85°C. The substitute provides a wider temperature operating window, suitable for applications requiring extended thermal range operation.

Q: Does the substitute part have better mechanical durability?

A: The 1571630-2 is rated for 15,000 electrical cycles compared to the MSS225RG's 10,000 cycles, indicating improved durability for repetitive switching applications.

Q: Are both parts RoHS compliant?

A: Yes, both the MSS225RG and 1571630-2 are ROHS3 compliant, meeting current environmental regulations for electronic components.
