SW-T2-4E-A-A2-MA2 Equivalent & Substitute Parts

Part Overview

The SW-T2-4E-A-A2-MA2 is a miniature toggle switch manufactured by Adam Tech, configured as a Double Pole Double Throw (DPDT) panel mount switch with On-Off-On functionality. This switch is rated for 6A AC at 125V and features a solder lug termination style with a standard round actuator. The part is currently Active in product status with 928 units in stock.

Substitute parts are identified when equivalent electrical ratings, mechanical mounting configurations, and circuit topologies are available from alternative manufacturers. This reference page identifies functionally compatible alternatives that maintain the same switching characteristics and panel integration requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SW-T2-4E-A-A2-MA2 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must be DPDT
• AC current rating must be 6A or greater
• AC voltage rating must be 125V or greater
• Switch function must be On-Off-On

Mechanical Compatibility Requirements:

• Mounting type must be Panel Mount
• Termination style must be Solder Lug
• Actuator type must be Standard Round
• Panel cutout dimensions must accommodate a circular opening (6.00mm diameter or compatible)
• Bushing thread must be M6 x 0.75

Regulatory Compliance:

• RoHS3 compliance required
• REACH Unaffected status required

The substitute part M2023SS4W01 from NKK Switches meets all electrical and mechanical compatibility criteria, with the following considerations: panel cutout diameter is 6.50mm (larger than the 6.00mm requirement), actuator length differs slightly (10.50mm versus 11.00mm), and electrical life rating is higher (25,000 cycles versus 10,000 cycles).

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: SW-T2-4E-A-A2-MA2 (Adam Tech)

The SW-T2-4E-A-A2-MA2 is the recommended primary selection for new designs and applications. This part maintains Active product status, ensuring long-term availability and supply chain stability. The component is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Alternative Selection: M2023SS4W01 (NKK Switches)

The M2023SS4W01 is available as a functional equivalent for applications where the SW-T2-4E-A-A2-MA2 is unavailable. This part carries Obsolete product status, indicating limited future availability. The M2023SS4W01 meets all electrical and mechanical compatibility requirements and maintains equivalent regulatory compliance (ROHS3 compliant, REACH unaffected).

Selection Considerations:

The M2023SS4W01 features a larger panel cutout diameter (6.50mm versus 6.00mm), which requires verification that the panel mounting hole can accommodate the larger dimension. The actuator length difference (10.50mm versus 11.00mm) is 0.50mm shorter, which may affect user interface ergonomics in applications with space constraints. The M2023SS4W01 provides extended electrical life (25,000 cycles versus 10,000 cycles) and expanded DC voltage rating (30V), offering enhanced durability in high-cycle applications.

Frequently Asked Questions (FAQ)

Q: Can the M2023SS4W01 be used as a direct replacement for the SW-T2-4E-A-A2-MA2?

A: The M2023SS4W01 is electrically and functionally compatible with the SW-T2-4E-A-A2-MA2 for DPDT On-Off-On switching applications at 6A AC / 125V. Panel mounting compatibility requires verification that the larger 6.50mm cutout diameter accommodates the existing panel hole or that the panel can be modified. The 0.50mm difference in actuator length may affect mechanical fit in confined spaces.

Q: What are the key electrical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: DPDT circuit configuration, 6A AC current rating or higher, 125V AC voltage rating or higher, and On-Off-On switch function. Both parts meet these criteria. The M2023SS4W01 additionally provides 3A DC / 30V DC capability, which is not specified for the SW-T2-4E-A-A2-MA2.

Q: Are there compliance or regulatory differences between these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. No regulatory compliance differences exist between the two components. Both are suitable for applications requiring RoHS3 certification.

Q: What is the significance of the Obsolete product status for the M2023SS4W01?

A: Obsolete product status indicates that the M2023SS4W01 is no longer in active production and future availability is limited. This part should be used only when the active SW-T2-4E-A-A2-MA2 is unavailable. For new designs, the SW-T2-4E-A-A2-MA2 is the recommended selection to ensure long-term supply chain continuity.

Q: How do the electrical life ratings differ between these parts?

A: The SW-T2-4E-A-A2-MA2 is rated for 10,000 electrical cycles, while the M2023SS4W01 is rated for 25,000 electrical cycles. The M2023SS4W01 provides extended operational life, making it suitable for high-cycle switching applications where durability is a primary concern.

Q: Are the panel mounting dimensions compatible?

A: Both parts use M6 x 0.75 bushing threads for panel mounting. The primary difference is the panel cutout diameter: the SW-T2-4E-A-A2-MA2 requires a 6.00mm circular opening, while the M2023SS4W01 requires a 6.50mm circular opening. Existing panels designed for the SW-T2-4E-A-A2-MA2 may require enlargement to accommodate the M2023SS4W01.
