MSTS2332K Equivalent & Substitute Parts

Part Overview

The MSTS2332K is a slide switch manufactured by APEM Inc., configured as a DP3T (Double Pole Three Throw) switch rated for 300mA at 28V DC. This component features through-hole mounting with PC pin termination and epoxy sealed terminals. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

The OS203011MS1QP1 manufactured by C&K qualifies as a direct substitute for the MSTS2332K based on the following critical parameters:

Matching Parameters:

• Circuit configuration: DP3T
• Current rating: 300mA (DC)
• Mounting type: Through Hole
• Termination style: PC Pin
• Actuator type: Standard
• Actuator length: 4.00mm
• Contact finish: Silver
• Electrical life: 10,000 Cycles
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Allowable Variations:

• Voltage rating: 30V (substitute) vs. 28V (original) — the substitute exceeds the original specification
• Operating temperature range: -30°C ~ 70°C (substitute) vs. -20°C ~ 85°C (original) — partial overlap with reduced upper temperature limit
• Switch travel: 2.00mm (substitute) vs. 2.50mm (original) — within acceptable mechanical tolerance
• Contact material: Copper Alloy (substitute) vs. Brass (original) — both provide equivalent electrical performance
• Actuator material: Polyoxymethylene/Acetal (substitute) vs. Polyacetal (original) — functionally equivalent materials

Parameter Comparison

Engineering Selection Recommendations

The OS203011MS1QP1 is suitable as a substitute for the MSTS2332K in applications where the operating voltage does not exceed 28V DC and the upper operating temperature requirement does not exceed 70°C. Both components maintain ROHS3 compliance and equivalent electrical life ratings. The substitute part is currently in active production status with substantial inventory availability (8909 pcs), whereas the original part is obsolete. Selection of the substitute should be based on circuit voltage and temperature envelope compatibility with the target application.

Frequently Asked Questions (FAQ)

Q: Can the OS203011MS1QP1 be used in place of the MSTS2332K in all applications?

A: The OS203011MS1QP1 is compatible with applications operating at 28V DC or lower. If your circuit operates above 28V or requires sustained operation above 70°C, substitution is not appropriate.

Q: What is the significance of the different switch travel specifications?

A: The MSTS2332K has 2.50mm travel while the OS203011MS1QP1 has 2.00mm travel. This difference affects actuator engagement distance. Verify that your mechanical design accommodates the reduced travel of the substitute part.

Q: Are the contact materials functionally equivalent?

A: Both brass and copper alloy contacts with silver finish provide equivalent electrical performance for this application class. The material difference does not affect switching capability or contact resistance characteristics.

Q: Why is the operating temperature range different?

A: The substitute part has a lower maximum operating temperature (70°C vs. 85°C). Confirm that your application does not require sustained operation above 70°C before selecting this substitute.

Q: What is the advantage of selecting the OS203011MS1QP1?

A: The substitute part is in active production with high inventory availability, ensuring long-term supply continuity. The original MSTS2332K is obsolete and subject to availability constraints.
