Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB2011SS4W03 is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must be SPDT
• Switch function must be On-Momentary
• Current rating must support minimum 6A AC at 125V or 3A DC at 30V
• Voltage ratings must meet or exceed specified thresholds

Mechanical Compatibility Requirements:

• Mounting type must be Panel Mount, Rear
• Actuator type must be Plunger for Cap
• Termination style must be PC Pin
• Panel cutout dimensions must accommodate Circular 6.50mm diameter

Environmental & Compliance Requirements:

• Operating temperature range must encompass -30°C to 85°C
• RoHS3 compliance required
• Moisture sensitivity level MSL 1 or better

The substitute part MBN15SS4W03 from NKK Switches meets these core substitution criteria, enabling functional equivalence in applications requiring the MB2011SS4W03.

Parameter Comparison

Engineering Selection Recommendations

The MBN15SS4W03 is classified as an active product from NKK Switches, providing supply continuity for applications currently using the obsolete MB2011SS4W03. Both components share identical electrical specifications including SPDT circuit configuration, on-momentary function, and current/voltage ratings.

The primary distinction between these components is the mounting type: the MB2011SS4W03 uses panel mount rear installation, while the MBN15SS4W03 employs bushing mount configuration. This difference requires mechanical evaluation during integration to ensure compatibility with existing panel cutout geometry and installation methodology.

Both components maintain RoHS3 compliance and MSL 1 moisture sensitivity rating, supporting deployment in standard industrial and commercial environments. The active product status of MBN15SS4W03 ensures ongoing availability and supply chain reliability for new designs and replacement applications.

Frequently Asked Questions (FAQ)

Q: Can MBN15SS4W03 directly replace MB2011SS4W03 in existing assemblies?

A: Electrical substitution is valid based on matching SPDT circuit, on-momentary function, and identical current/voltage ratings. Mechanical compatibility requires verification of mounting type differences. The MB2011SS4W03 uses panel mount rear installation while MBN15SS4W03 uses bushing mount configuration. Panel cutout geometry and installation hardware must be evaluated for compatibility.

Q: What are the critical parameters for determining substitution eligibility?

A: Substitution eligibility is determined by: SPDT circuit configuration, on-momentary switch function, minimum 6A AC at 125V and 3A DC at 30V current/voltage ratings, plunger actuator type, PC pin termination, operating temperature range of -30°C to 85°C, and RoHS3 compliance status.

Q: Why is the MB2011SS4W03 classified as obsolete?

A: The MB2011SS4W03 is designated obsolete by the manufacturer, indicating discontinued production. The active substitute MBN15SS4W03 provides equivalent electrical functionality for ongoing system support and new design implementations.

Q: Are there packaging differences between these components?

A: The MB2011SS4W03 packaging specification is not provided in the technical data. The MBN15SS4W03 is supplied in bulk packaging format. Packaging requirements should be confirmed with the component supplier for procurement planning.

Q: Do both components meet the same environmental and compliance standards?

A: Both components are RoHS3 compliant and rated for MSL 1 moisture sensitivity, supporting deployment in standard industrial environments. Operating temperature range of -30°C to 85°C is specified for the MB2011SS4W03; equivalent environmental specifications for MBN15SS4W03 should be confirmed with the manufacturer.
