M2033SS1G01 Toggle Switch 3PDT Equivalent & Substitute Parts

Part Overview

The M2033SS1G01 is a 3PDT panel mount toggle switch manufactured by NKK Switches, rated for 0.4VA at 28V with an On-Off-On switching function. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. The switch features epoxy sealed terminals, solder lug termination, and operates across a temperature range of -30°C to 85°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2033SS1G01 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration must be 3PDT
• Switch function must be On-Off-On
• Mounting type must be Panel Mount
• Termination style must be Solder Lug
• Bushing thread must be 1/4-40
• Panel cutout diameter must accommodate 6.50mm or smaller
• Actuator type must be Standard Round

Electrical Performance Criteria:

• Current rating must meet or exceed 0.4VA
• Voltage ratings (AC and DC) must meet or exceed 28V
• Operating temperature range must encompass -30°C to 85°C

Compliance Criteria:

• RoHS3 compliance required
• MSL rating of 1 (Unlimited) preferred

The identified substitute parts meet these core requirements while offering variations in manufacturer, actuator length, panel cutout dimensions, and electrical life specifications.

Parameter Comparison

Engineering Selection Recommendations

5659AB (APEM Inc.) is suitable for applications requiring higher current capacity and voltage ratings. This part is active in production, ensuring long-term availability. The extended operating temperature range (-40°C to 85°C) provides additional thermal margin. However, the reduced electrical life specification (40,000 cycles versus 50,000 cycles) should be evaluated against application duty cycle requirements. ROHS3 compliance and MSL 1 rating match the original specification.

7303SYZBE (C&K) maintains electrical performance parity with the M2033SS1G01 at 0.4VA and identical operating temperature range. This part is active in production with ROHS3 compliance. The panel cutout diameter is 6.35mm, which is smaller than the original 6.50mm specification and may require panel modification. Actuator length variation (10.67mm versus 10.50mm) is minimal. REACH status differs from the original part, requiring compliance verification for specific applications. Electrical life is reduced to 40,000 cycles.

Both substitute parts satisfy the core functional and electrical requirements for 3PDT On-Off-On panel mount toggle switches with solder lug termination and 1/4-40 bushing threads.

Frequently Asked Questions (FAQ)

Q: Can the 5659AB replace the M2033SS1G01 in all applications?

A: The 5659AB meets all core functional requirements: 3PDT circuit, On-Off-On function, panel mount configuration, and solder lug termination. However, the higher current rating (6A AC / 4A DC) and voltage rating (125V AC / 30V DC) indicate this part is designed for higher-power applications. Verify that your circuit design does not depend on the lower current rating of the original part. Electrical life is reduced from 50,000 to 40,000 cycles.

Q: Why does the 7303SYZBE have a smaller panel cutout diameter?

A: The 7303SYZBE specifies a 6.35mm panel cutout diameter compared to the 6.50mm of the M2033SS1G01. This difference requires verification of panel hole dimensions. If the existing panel is drilled for 6.50mm, the 7303SYZBE may not fit without panel modification or use of a larger bushing.

Q: Are both substitute parts available in the same packaging as the original?

A: The M2033SS1G01 is packaged in standard format. The 5659AB is supplied in Tray packaging, while the 7303SYZBE is supplied in Bulk packaging. Confirm packaging compatibility with your procurement and assembly processes.

Q: What is the impact of the REACH status difference in the 7303SYZBE?

A: The 7303SYZBE is marked as REACH Affected, while the M2033SS1G01 is REACH Unaffected. This indicates the C&K part may contain substances of concern under REACH regulations. Applications subject to REACH compliance requirements must evaluate this difference against regulatory obligations.

Q: Can I use the 5659AB if my application requires 50,000 electrical cycles?

A: The 5659AB is rated for 40,000 electrical cycles, which is 10,000 cycles less than the M2033SS1G01. If your application requires 50,000 cycles, the 5659AB does not meet this specification. The 7303SYZBE also specifies 40,000 cycles. Evaluate actual duty cycle requirements against rated electrical life.

Q: Are all three parts RoHS3 compliant?

A: Yes. The M2033SS1G01, 5659AB, and 7303SYZBE are all ROHS3 compliant. All three parts carry MSL 1 (Unlimited) moisture sensitivity ratings.
