Key Parameters

Substitute Part Grouping Explanation

The MB2011LS1W03-CA has been identified with one manufacturer-recommended substitute: MBN15LS1W03-CA, also manufactured by NKK Switches. Substitution eligibility is determined by the following critical parameters:

• Circuit configuration (SPDT)
• Current and voltage ratings (6A AC / 125V AC; 3A DC / 30V DC)
• Mounting type (Panel Mount, Rear)
• Actuator type (Round, Button)
• Termination style (PC Pin)
• Panel cutout dimensions (Circular - 6.50mm Dia)
• Operating temperature range (-30°C ~ 85°C)
• RoHS3 compliance status

The substitute part maintains compatibility across these electrical and mechanical parameters, enabling direct functional replacement in legacy applications.

Frequently Asked Questions (FAQ)

Q: Why is the MB2011LS1W03-CA marked as obsolete?

A: The MB2011LS1W03-CA has reached end-of-life status. NKK Switches has designated the MBN15LS1W03-CA as the active replacement, which maintains the same electrical and mechanical specifications.

Q: Can the MBN15LS1W03-CA be used as a direct replacement?

A: Yes. The MBN15LS1W03-CA is the manufacturer-recommended substitute and shares identical termination style, circuit configuration, and rated electrical parameters with the original MB2011LS1W03-CA.

Q: Are there any differences in packaging or handling?

A: Both components are supplied in bulk packaging. The MBN15LS1W03-CA has a Moisture Sensitivity Level designation of Not Applicable, compared to MSL 1 (Unlimited) for the original part. This indicates improved moisture resistance in the substitute.

Q: What are the key electrical parameters to verify during substitution?

A: Verify that the replacement maintains 6A AC / 125V AC and 3A DC / 30V DC ratings, SPDT circuit configuration, and PC Pin termination for compatibility with existing circuit designs and PCB layouts.

Q: Is the substitute part RoHS compliant?

A: Yes. The MBN15LS1W03-CA is ROHS3 compliant, matching the regulatory status of the original MB2011LS1W03-CA.
