NKK Switches M2023SS4W01 Equivalent & Substitute Parts

Part Overview

The NKK Switches M2023SS4W01 is a toggle switch with DPDT (Double Pole Double Throw) circuit configuration, rated for 6A AC at 125V and 3A DC at 30V. This panel-mount switch features a standard round actuator with solder lug termination and is designed for On-Off-On switching applications. The product is classified as obsolete, making identification of equivalent and substitute parts essential for system maintenance, repair, and redesign applications where continued supply cannot be guaranteed.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the M2023SS4W01 are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Circuit configuration (DPDT)
• Switch function (On-Off-On)
• Current rating (minimum 6A AC)
• Voltage rating (minimum 125V AC)
• Mounting type (Panel Mount)
• Termination style (Solder Lug)
• Panel cutout dimensions (circular, compatible with M6 x 0.75 bushing)

Substitute Categories:

1. MFR Recommended Substitute (MN23SS4W01): NKK Switches manufacturer-recommended equivalent. Maintains the same manufacturer lineage and core electrical specifications.

2. Similar Substitute (SW-T2-4E-A-A2-MA2): Adam Tech alternative meeting primary electrical and mechanical requirements with minor parameter variations within acceptable engineering tolerances.

Parameter Comparison

Engineering Selection Recommendations

MN23SS4W01 (MFR Recommended Substitute): This part is the preferred substitute as it is manufactured by NKK Switches, the original equipment manufacturer. Active product status ensures ongoing availability and support. ROHS3 compliance and EAR99 classification match the original part specifications. Selection of this substitute eliminates supply chain risk associated with the obsolete M2023SS4W01.

SW-T2-4E-A-A2-MA2 (Similar Substitute): This Adam Tech alternative meets the primary electrical requirements (6A AC, 125V AC, DPDT, On-Off-On configuration) and mechanical specifications (Panel Mount, Solder Lug, M6 x 0.75 bushing). Active product status provides supply continuity. ROHS3 compliance and EAR99 classification are maintained. Engineering consideration should be given to the reduced panel cutout diameter (6.00mm versus 6.50mm), reduced electrical life rating (10,000 cycles versus 25,000 cycles), and slightly higher operating temperature minimum (-25°C versus -30°C). This substitute is suitable for applications where these parameter variations are acceptable.

Frequently Asked Questions (FAQ)

Q: Can MN23SS4W01 be used as a direct replacement for M2023SS4W01? A: Yes. MN23SS4W01 is the NKK Switches manufacturer-recommended equivalent and maintains compatibility with the original part's electrical and mechanical specifications.

Q: What are the key differences between SW-T2-4E-A-A2-MA2 and the original M2023SS4W01? A: The Adam Tech substitute maintains equivalent electrical performance (6A AC, 125V AC, DPDT) and mechanical mounting (Panel Mount, M6 x 0.75 bushing). Differences include: panel cutout diameter reduced from 6.50mm to 6.00mm, electrical life reduced from 25,000 to 10,000 cycles, operating temperature minimum raised from -30°C to -25°C, and actuator length increased from 10.50mm to 11.00mm.

Q: Are both substitute parts RoHS compliant? A: Yes. Both MN23SS4W01 and SW-T2-4E-A-A2-MA2 are ROHS3 compliant, matching the original M2023SS4W01 specification.

Q: What is the impact of the reduced panel cutout diameter in SW-T2-4E-A-A2-MA2? A: The panel cutout diameter is reduced from 6.50mm to 6.00mm. This requires verification that the panel mounting hole can accommodate the smaller diameter without compromising mechanical integrity or sealing characteristics.

Q: Does the reduced electrical life of SW-T2-4E-A-A2-MA2 affect suitability? A: The electrical life rating is reduced from 25,000 cycles to 10,000 cycles. Applications requiring high-cycle switching operations should evaluate whether this reduction impacts system reliability and maintenance intervals.

Q: What packaging options are available for these substitutes? A: MN23SS4W01 is supplied in Bulk packaging. SW-T2-4E-A-A2-MA2 is supplied in Bag packaging. Verify packaging requirements for your procurement and assembly processes.
