ST22KMV2B Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The ST22KMV2B is a toggle switch with DPDT (Double Pole Double Throw) configuration manufactured by APEM Inc. This panel-mount, right-angle switch is rated for 0.4VA at 20V AC/DC and features a standard round actuator with PC pin termination. The product is currently obsolete, making equivalent substitute parts necessary for ongoing maintenance, repair, and new design implementations where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ST22KMV2B is determined by strict alignment of the following critical parameters:

• Circuit configuration (DPDT)
• Switch function (On-Off-On)
• Electrical ratings (0.4VA at 20V AC/DC)
• Mounting interface (Panel Mount, Right Angle, Vertical)
• Mechanical interface (Standard Round actuator, PC pin termination, 6.35mm circular cutout, 1/4-40 bushing thread)
• Operating temperature range (-30°C ~ 85°C)
• Electrical life (40,000 cycles minimum)

The C&K 7203SYAV2BE meets all these criteria and qualifies as a direct substitute. Minor variations in actuator length (10.67mm vs 10.41mm) and actuator material finish (Chrome Plated vs Nickel Plated) do not affect functional compatibility within the specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7203SYAV2BE is a qualified substitute for the obsolete ST22KMV2B. Both parts meet ROHS3 compliance requirements and share identical electrical specifications and mechanical interfaces. The 7203SYAV2BE maintains active product status, ensuring ongoing availability and supply chain continuity.

The 7203SYAV2BE is available in bulk packaging with 782 units in current inventory. Selection of this substitute eliminates obsolescence risk while maintaining full functional and mechanical compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can the C&K 7203SYAV2BE directly replace the ST22KMV2B in existing applications?

A: Yes. Both switches share identical circuit configuration (DPDT), electrical ratings (0.4VA at 20V AC/DC), and mechanical interfaces (panel mount, 6.35mm circular cutout, 1/4-40 bushing thread, PC pin termination). The minor difference in actuator length (0.26mm) does not affect functional compatibility.

Q: What is the significance of the actuator length difference?

A: The ST22KMV2B has an actuator length of 10.41mm, while the 7203SYAV2BE measures 10.67mm. This 0.26mm difference is within typical mechanical tolerances and does not impact panel mounting or operational performance.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant. The 7203SYAV2BE is REACH Affected, while the ST22KMV2B is REACH Unaffected. Both carry the same ECCN (EAR99) and HTSUS classifications.

Q: Why is the ST22KMV2B marked as obsolete?

A: The ST22KMV2B is no longer in active production. The C&K 7203SYAV2BE provides equivalent functionality and is actively manufactured, making it the appropriate choice for new designs and ongoing supply requirements.

Q: What packaging options are available for the substitute part?

A: The C&K 7203SYAV2BE is supplied in bulk packaging with 782 units currently in stock.
