MS13 Slide Switch SP3T Equivalent & Substitute Parts

Part Overview

The MS13 is an active SP3T slide switch manufactured by APEM Inc., rated for 300mA at 6V DC with through-hole mounting. This component is designed for applications requiring three-position switching with on-on-on functionality. Substitute parts become necessary when the MS13 reaches end-of-life status, inventory constraints occur, or design requirements necessitate alternative electrical ratings or contact materials.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MS13 is determined by the following critical parameters:

Circuit Configuration: SP3T topology must be maintained for functional equivalence.

Mounting and Termination: Through-hole mounting with PC pin termination is required for PCB compatibility.

Physical Dimensions: Actuator length (2.00mm) and switch travel (2.00mm) must match to ensure mechanical fit and actuation characteristics.

Electrical Life: Minimum 10,000 cycles required to maintain operational reliability.

Compliance: ROHS3 compliance and REACH unaffected status must be preserved.

The substitute parts CL-SB-13C-01 and CL-SB-13C-02 satisfy these core substitution criteria. Both are SP3T slide switches with through-hole PC pin termination, identical actuator dimensions, and equivalent electrical life ratings. However, electrical parameter differences exist: both substitutes are rated for 200mA at 12V, which represents a higher voltage capability but lower current rating compared to the MS13. Contact material and finish variations between substitutes provide options for different application requirements.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment and supply chain viability.

The MS13 operates within a 6V/300mA envelope. The substitute parts CL-SB-13C-01 and CL-SB-13C-02 operate at 12V/200mA. Selection between the main part and substitutes depends on circuit voltage and current requirements. If the application operates at 6V and requires 300mA switching capacity, the MS13 remains the appropriate choice. If the application operates at 12V or lower current demands (≤200mA), either substitute is functionally equivalent.

Between the two Nidec substitutes, CL-SB-13C-01 features silver contact finish, while CL-SB-13C-02 features gold contact finish. Gold plating provides enhanced corrosion resistance and contact reliability in demanding environments. Both substitutes specify non-shorting (BBM) contact timing and polyamide actuator material, with operating force ratings of 160/260gf.

The extended operating temperature range of the substitutes (-40°C to 85°C versus -10°C to 60°C) provides additional thermal margin for applications with wider environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can CL-SB-13C-01 or CL-SB-13C-02 directly replace MS13 in a 6V circuit?

A: Both substitutes are rated for 12V operation. In a 6V circuit, they will function correctly as the voltage rating represents maximum capability, not a requirement. However, verify that the 200mA current rating meets application demands, as it is lower than the MS13's 300mA rating.

Q: What is the difference between CL-SB-13C-01 and CL-SB-13C-02?

A: The primary difference is contact finish. CL-SB-13C-01 uses silver contact finish, while CL-SB-13C-02 uses gold contact finish. All other electrical and mechanical parameters are identical. Gold finish provides superior corrosion resistance in harsh or humid environments.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts share identical actuator length (2.00mm), switch travel (2.00mm), and through-hole PC pin termination, ensuring mechanical and electrical compatibility on the same PCB footprint.

Q: Do the substitutes maintain the same electrical life rating?

A: Yes. All three parts are rated for 10,000 electrical cycles, ensuring equivalent operational longevity.

Q: What compliance certifications apply to all parts?

A: All three parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component distribution and use.
