Switch function: On-On
Mounting type: Panel Mount
Termination style: Solder Lug
Bushing thread: 1/4-40
Operating temperature range: -30°C to 85°C minimum
RoHS3 compliance

Electrical Performance Criteria:

Current rating must meet or exceed application requirements (6A AC / 4A DC for the original)
Voltage rating must meet or exceed application requirements (125V AC / 30V DC for the original)

Engineering Selection Recommendations

NKK Switches MN32LL1W01 – Active product status from the original manufacturer. Recommended as the primary replacement when electrical specifications align with application requirements. Electrical parameters not specified in available data; contact manufacturer for detailed ratings before selection.

E-Switch 1003P1K2B25M1QEH – Active product with 5A AC/DC rating at 120V AC and 28V DC. Suitable for applications where the original 6A AC / 4A DC specification can be reduced to 5A. Extended electrical life of 40,000 cycles. Panel cutout diameter 6.35mm is compatible with 1/4-40 bushing. ROHS3 compliant.

C&K 7301K12CWZQE, 7301K12ZGE, 7301K12ZQE – Active products rated 5A AC/DC at 120V AC and 28V DC. Suitable for applications with reduced power requirements. All three variants provide 100,000-cycle electrical life. Panel cutout 6.35mm compatible with 1/4-40 bushing. ROHS3 compliant. 7301K12CWZQE and 7301K2CWZQE include IP67 ingress protection.

C&K 7301K2CWZQE, 7301K2CWZQE2 – Active products rated 5A AC/DC at 120V AC and 28V DC with 100,000-cycle electrical life. Both include IP67 ingress protection. 7301K2CWZQE2 features black anodized finish. Panel cutout 6.35mm compatible with 1/4-40 bushing. ROHS3 compliant.

C&K 7301K12CWZBE, 7301K12ZBE, 7301K2CWZBE – Reduced-rating variants with 0.4VA specification at 20V AC/DC. Suitable only for low-power signal switching applications. Not recommended for applications requiring the original 6A AC / 4A DC performance. 100,000-cycle electrical life. ROHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 1003P1K2B25M1QEH replace the M2032LL1W01 in all applications?

A: The E-Switch part is suitable only for applications where the circuit can operate at 5A AC/DC instead of the original 6A AC / 4A DC. Verify that your application does not require the full current capacity of the original part before substitution.

Q: What is the difference between the C&K 7301K12 and 7301K2 series?

A: The primary difference is actuator length: 7301K12 series has 18.59mm actuator length, while 7301K2 series has 17.88mm. Both are compatible with 1/4-40 bushing and 6.35mm panel cutout. Select based on available panel space and actuator clearance requirements.

Q: Are the C&K parts with 0.4VA rating suitable replacements?

A: No. The 0.4VA rating is significantly lower than the original 6A specification and is intended for low-power signal switching only. These parts are not suitable for general-purpose switching applications requiring the original current capacity.

Q: Do all substitute parts have the same panel mounting compatibility?

A: All substitute parts use 1/4-40 bushing thread. Panel cutout diameter is 6.35mm for C&K and E-Switch parts versus 6.50mm for the original NKK part. Both diameters are compatible with standard 1/4-40 panel mount hardware. Verify panel hole dimensions before installation.

Q: Which substitute offers the longest electrical life?

A: C&K 7301 series parts (all variants) provide 100,000-cycle electrical life, compared to 25,000 cycles for the original M2032LL1W01 and 40,000 cycles for the E-Switch part.

Q: Is the NKK Switches MN32LL1W01 a direct replacement?

A: MN32LL1W01 is an active NKK product and the recommended primary alternative. However, complete electrical specifications are not provided in available documentation. Contact NKK Switches directly to confirm that MN32LL1W01 meets your application's current and voltage requirements before selection.
