MS22R Equivalent & Substitute Parts

Part Overview

The MS22R is a slide switch manufactured by APEM Inc., configured as a Double Pole Double Throw (DPDT) switch with a 300mA DC current rating at 6V. This component features a through-hole, right-angle mounting configuration with PC pin termination and silver contact finish. The product is classified as obsolete, making equivalent substitutes necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MS22R is determined by the following critical parameters:

• Circuit configuration must be DPDT
• Switch function must be On-On
• Mounting type must be Through Hole, Right Angle
• Termination style must be PC Pin
• Current and voltage ratings must meet or exceed the application requirements
• Operating temperature range must encompass the intended use environment

The three substitute parts identified (1825010-4, 1825011-4, and SSB22R) all satisfy the core electrical and mechanical compatibility criteria. However, they differ in current/voltage ratings, contact materials, and product status, which determines their suitability for specific applications.

Parameter Comparison

Engineering Selection Recommendations

1825010-4 (TE Connectivity ALCOSWITCH ASE Series)

This substitute is suitable for applications where the MS22R current requirement of 300mA can be accommodated by the 0.4VA rating. The 20V DC rating exceeds the original 6V specification, providing design margin. Active product status ensures long-term availability. ROHS3 compliance aligns with modern manufacturing standards. The gold contact finish and extended operating temperature range (-40°C to 80°C) offer enhanced reliability in demanding environments.

1825011-4 (TE Connectivity ALCOSWITCH ASF Series)

This substitute shares electrical specifications with the 1825010-4 but features a screwdriver slot actuator with flush length, differing from the standard actuator of the MS22R. Obsolete product status limits procurement viability for new designs. The 0.4VA rating and 20V DC specification provide electrical compatibility. Use this substitute only when existing inventory or legacy system requirements mandate the specific actuator configuration.

SSB22R (TE Connectivity ALCOSWITCH SSB Series)

This substitute provides the closest current rating match at 100mA DC, though still below the original 300mA specification. The 30V DC rating exceeds the 6V requirement. Active product status ensures availability. Silver contact finish matches the MS22R. Operating temperature range extends to 85°C. This substitute is appropriate for applications where the 100mA current rating is sufficient and higher voltage margin is beneficial.

Frequently Asked Questions (FAQ)

Q: Can the 1825010-4 directly replace the MS22R in a 300mA application?

A: The 1825010-4 is rated for 0.4VA AC/DC. In DC applications at 20V, this equates to 20mA maximum, which is insufficient for a 300mA requirement. This substitute is suitable only for applications where the actual current draw is significantly lower than the original 300mA specification.

Q: What is the difference between the 1825010-4 and 1825011-4?

A: Both parts share identical electrical specifications (0.4VA, 20V DC, DPDT, On-On). The primary difference is the actuator type: 1825010-4 features a standard actuator with 2.67mm length, while 1825011-4 features a screwdriver slot actuator with flush length. Select based on mechanical interface requirements.

Q: Is the SSB22R suitable for the original MS22R application?

A: The SSB22R is suitable only if the application current requirement does not exceed 100mA DC. At 300mA, this substitute would exceed its rated capacity. Verify actual circuit current draw before selection.

Q: Why do the substitute parts have higher voltage ratings than the MS22R?

A: Higher voltage ratings provide design margin and allow the same switch to be used across multiple voltage platforms. A 20V or 30V rated switch operates safely at 6V with no performance degradation.

Q: Are all substitutes RoHS compliant?

A: The 1825010-4 is ROHS3 compliant. The 1825011-4 and SSB22R have RoHS status listed as "Not Applicable," indicating they may not meet current RoHS requirements. Verify compliance requirements for your application before selection.

Q: What is the contact timing difference between these switches?

A: The MS22R does not specify contact timing. The 1825010-4, 1825011-4, and SSB22R all feature shorting contact timing (Make-Before-Break), which ensures continuity during switching transitions.
