ST22KMV2Q Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The ST22KMV2Q is a toggle switch manufactured by APEM Inc., featuring DPDT (Double Pole Double Throw) circuitry with On-Off-On switching function. This panel-mount component is rated for 6A at 125V AC and 7A at 30V DC, with a standard round actuator and PC pin termination. The product is currently obsolete, making equivalent substitutes necessary for ongoing maintenance, repair, and new design applications where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ST22KMV2Q is determined by the following critical parameters:

• Circuit Configuration: Must be DPDT to maintain electrical functionality
• Switch Function: Must be On-Off-On to preserve operational behavior
• Mounting Type: Must be Panel Mount, Right Angle, Vertical for mechanical compatibility
• Panel Cutout Dimensions: Must be Circular - 6.35mm Dia for panel integration
• Bushing Thread: Must be 1/4-40 for secure fastening
• Termination Style: Must be PC Pin for PCB connection compatibility
• Actuator Type: Must be Standard Round for user interface consistency
• Current and Voltage Ratings: Substitute must meet or exceed the original ratings (6A AC at 125V AC minimum; 7A DC at 30V DC minimum)
• Operating Temperature Range: Must support -30°C to 85°C operation
• Electrical Life: Must provide 40,000 cycles minimum

The 7203SYAV2QE from C&K meets all mechanical and functional requirements while maintaining electrical compatibility within acceptable tolerances.

Parameter Comparison

Engineering Selection Recommendations

The 7203SYAV2QE from C&K is a direct functional substitute for the obsolete ST22KMV2Q. Both components share identical circuit configuration, switch function, mounting specifications, and termination style. The substitute maintains ROHS3 compliance and supports the same operating temperature range.

Key considerations for selection:

• Current and Voltage Ratings: The 7203SYAV2QE is rated for 5A AC/DC at 120V AC and 28V DC, which are lower than the original ST22KMV2Q specifications (6A AC at 125V AC; 7A DC at 30V DC). Applications operating at or near the original maximum ratings require evaluation to confirm the substitute's adequacy.
• Product Status: The 7203SYAV2QE is active and currently manufactured, ensuring long-term availability compared to the obsolete ST22KMV2Q.
• Mechanical Compatibility: Identical panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), and actuator specifications ensure direct mechanical replacement without panel modification.
• Compliance: Both components meet ROHS3 requirements. The 7203SYAV2QE is REACH Affected, whereas the original is REACH Unaffected; compliance verification may be required depending on end-use jurisdiction.

Frequently Asked Questions (FAQ)

Q: Can the 7203SYAV2QE directly replace the ST22KMV2Q without panel modification?

A: Yes. Both components feature identical panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), and mounting orientation (Panel Mount, Right Angle, Vertical). No panel rework is required for mechanical installation.

Q: What is the impact of the lower current and voltage ratings on the 7203SYAV2QE?

A: The 7203SYAV2QE is rated for 5A AC/DC at 120V AC and 28V DC, compared to the ST22KMV2Q's 6A AC at 125V AC and 7A DC at 30V DC. Applications operating below these substitute ratings will function normally. Applications requiring the original maximum ratings must be evaluated to confirm the substitute's suitability for the specific load conditions.

Q: Are there differences in actuator length between these components?

A: The ST22KMV2Q has an actuator length of 10.41mm, while the 7203SYAV2QE measures 10.67mm. This 0.26mm difference is minimal and does not affect functional operation or user interface feel in standard panel-mount applications.

Q: What is the difference in product status between these components?

A: The ST22KMV2Q is obsolete and no longer manufactured. The 7203SYAV2QE is active and currently produced by C&K, ensuring availability for new designs and ongoing supply for maintenance applications.

Q: Are there compliance differences between the ST22KMV2Q and 7203SYAV2QE?

A: Both components are ROHS3 compliant. The ST22KMV2Q is REACH Unaffected, while the 7203SYAV2QE is REACH Affected. Applications subject to REACH regulations should confirm the substitute's compliance status for the intended market and end-use application.

Q: What is the electrical life rating for the 7203SYAV2QE?

A: The 7203SYAV2QE is rated for 40,000 electrical cycles, matching the original ST22KMV2Q specification.
