Key Parameters

Substitute Part Grouping Explanation

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

• Circuit configuration (SPDT)
• Switch function (On-Mom)
• Current and voltage ratings (6A/125V AC; 3A/30V DC)
• Mounting type (Panel Mount, Rear)
• Actuator type and color (Round Button, Green)
• Termination style (PC Pin)
• Panel cutout dimensions (Circular - 6.50mm Dia)
• Operating temperature range (-30°C to 85°C)
• Mechanical and electrical life specifications
• RoHS compliance status

The substitute part MBN15LS1W03-CF is identified as a manufacturer-recommended equivalent based on compatibility with these core electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can the MBN15LS1W03-CF directly replace the MB2011LS1W03-CF in existing applications?

A: The MBN15LS1W03-CF is the manufacturer-recommended substitute. Verify mounting configuration compatibility, as the main part uses panel mount rear termination while the substitute uses bushing mount configuration. Panel cutout dimensions and electrical specifications must be confirmed for your specific application.

Q: What is the difference between panel mount and bushing mount configurations?

A: Panel mount rear termination secures the switch from behind the panel with terminals extending rearward. Bushing mount uses a threaded bushing for front-panel installation. Installation method and panel preparation differ between these configurations.

Q: Are both parts RoHS3 compliant?

A: Yes, both the MB2011LS1W03-CF and MBN15LS1W03-CF are ROHS3 compliant, meeting current environmental and material restriction requirements.

Q: Why is the main part listed as obsolete?

A: The MB2011LS1W03-CF is obsolete and no longer in active production. The MBN15LS1W03-CF represents the current active equivalent from NKK Switches for this switch category.

Q: What electrical parameters must match for substitution?

A: Critical electrical parameters include circuit configuration (SPDT), switch function (On-Mom), current ratings (6A AC / 3A DC), and voltage ratings (125V AC / 30V DC). The substitute must maintain these specifications for functional compatibility.
