S202091MS02G Equivalent & Substitute Parts

Part Overview

The S202091MS02G is a slide switch manufactured by C&K, featuring DPDT (Double Pole Double Throw) configuration with On-On switching function. This component is rated for 6A AC at 125V and 1A DC at 125V, designed for through-hole mounting applications. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Alternative components may be required due to inventory constraints, application-specific voltage or current requirements, or design optimization needs.

Substitute Part Grouping Explanation

The substitute part 3-1825010-8 (TE Connectivity ALCOSWITCH Switches) is listed as an equivalent option. However, substitution between S202091MS02G and 3-1825010-8 requires careful evaluation based on the following critical parameters:

Circuit Configuration Difference: The main part uses DPDT (2 poles, 2 throws), while the substitute uses 6PDT (6 poles, 2 throws). This represents a significant functional difference in switching capability.

Electrical Ratings Difference: The main part is rated for 6A AC at 125V, while the substitute is rated for 0.4VA at 20V. These are substantially different power handling capabilities and voltage specifications.

Mechanical Specifications: Actuator length, switch travel, and operating force differ between the two parts, affecting physical fit and actuation characteristics.

Operating Temperature Range: The main part operates from -30°C to 65°C, while the substitute operates from -40°C to 80°C, providing a wider temperature envelope.

Electrical Life: The main part is rated for 10,000 cycles, while the substitute is rated for 15,000 cycles.

Substitution is only valid when the application requirements align with the substitute's lower voltage and current ratings, different circuit configuration, and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both S202091MS02G and 3-1825010-8 maintain active production status and ROHS3 compliance, ensuring regulatory alignment for new designs. Selection between these components must be driven by specific application requirements rather than interchangeability assumptions.

The S202091MS02G is appropriate for applications requiring 6A AC switching at 125V with DPDT functionality. The 3-1825010-8 is suitable only for low-voltage, low-current applications operating at 20V or below with requirements for 6-pole switching capability.

Direct substitution is not recommended without circuit redesign, as the voltage and current rating differences create incompatibility in most applications. The substitute part's lower electrical ratings and different pole configuration make it unsuitable as a drop-in replacement for the main part in standard 125V AC applications.

Frequently Asked Questions (FAQ)

Q: Can 3-1825010-8 be used as a direct replacement for S202091MS02G?

A: No. The substitute part has significantly lower voltage (20V vs. 125V) and current (0.4VA vs. 6A AC) ratings, along with a different circuit configuration (6PDT vs. DPDT). Direct substitution would result in component failure or malfunction in applications designed for the main part.

Q: What are the key differences in circuit configuration?

A: S202091MS02G provides 2 independent poles with 2 throws each (DPDT), allowing simultaneous switching of two separate circuits. The 3-1825010-8 provides 6 poles with 2 throws each (6PDT), enabling switching of up to 6 independent circuits. This functional difference requires circuit redesign for substitution.

Q: Are both parts suitable for 125V AC applications?

A: Only S202091MS02G is rated for 125V AC operation at 6A. The 3-1825010-8 is limited to 20V maximum, making it unsuitable for 125V AC applications without additional circuit modifications or voltage regulation.

Q: Do both parts share the same mounting and termination specifications?

A: Yes. Both components use through-hole mounting with PC pin termination, allowing for identical PCB footprint compatibility. However, electrical incompatibility prevents functional substitution.

Q: What is the operating temperature difference between these parts?

A: S202091MS02G operates from -30°C to 65°C, while 3-1825010-8 operates from -40°C to 80°C. The substitute part provides a wider temperature range, but this advantage is negated by its lower electrical ratings.

Q: Are both parts RoHS compliant?

A: Yes. Both S202091MS02G and 3-1825010-8 are ROHS3 compliant, meeting environmental and regulatory requirements for current manufacturing standards.
