Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB2011LS1W03-CE is determined by the following critical parameters:

• Circuit configuration (SPDT)
• Current and voltage ratings (6A/125V AC, 3A/30V DC)
• Mounting type (Panel Mount, Rear)
• Termination style (PC Pin)
• Panel cutout dimensions (Circular - 6.50mm Dia)
• Operating temperature range (-30°C to 85°C)
• Switch function (On-Mom)

The substitute part MBN15LS1W03-CE is identified as an equivalent component within the NKK Switches product family. Both components share the same electrical specifications and termination characteristics, enabling direct functional replacement in applications requiring SPDT pushbutton switch functionality.

Parameter Comparison

Engineering Selection Recommendations

The MBN15LS1W03-CE serves as an active substitute for the obsolete MB2011LS1W03-CE. Selection of the substitute component is justified by:

• Identical SPDT circuit configuration and On-Mom switch function
• Matching PC pin termination style for direct electrical connection
• Active product status ensuring continued availability and supply chain reliability
• Equivalent electrical performance within specified current and voltage parameters

The primary distinction between the main part and substitute is the mounting configuration: the MB2011LS1W03-CE uses panel mount rear termination, while the MBN15LS1W03-CE employs bushing mount design. This difference requires mechanical evaluation during integration to confirm compatibility with the target application's panel geometry and mounting requirements.

Frequently Asked Questions (FAQ)

Q: Can the MBN15LS1W03-CE directly replace the MB2011LS1W03-CE in all applications?

A: Electrical compatibility is confirmed through matching SPDT circuit configuration, switch function, and PC pin termination. However, the mounting type difference (panel mount rear vs. bushing mount) requires verification that the target application's mechanical interface accommodates the substitute's mounting design.

Q: What is the primary reason for seeking a substitute for the MB2011LS1W03-CE?

A: The MB2011LS1W03-CE is classified as obsolete. The MBN15LS1W03-CE is an active product within the NKK Switches portfolio, providing assured long-term availability and supply continuity.

Q: Are the electrical ratings identical between the two parts?

A: Both components share the same SPDT circuit configuration and On-Mom switch function with PC pin termination. Specific current and voltage ratings for the MBN15LS1W03-CE should be confirmed against the application's electrical requirements.

Q: What compliance certifications apply to these components?

A: The MB2011LS1W03-CE is ROHS3 compliant. Compliance status for the MBN15LS1W03-CE should be verified with the manufacturer for applications requiring specific regulatory certifications.

Q: How do the mechanical specifications differ?

A: The MB2011LS1W03-CE features panel mount rear termination with a 6.50mm circular panel cutout. The MBN15LS1W03-CE uses bushing mount design. Panel geometry and mounting hole specifications must be evaluated for compatibility.
