Key Parameters

Substitute Part Grouping Explanation

The substitute part MBN15SS1W03-BF is identified as a compatible alternative based on the following critical parameters:

Electrical Compatibility Criteria:

• SPDT circuit configuration maintained
• Current and voltage ratings support the original application requirements
• PC pin termination style preserved for direct circuit board integration

Mechanical Compatibility Criteria:

• Panel mount configuration compatible with existing mechanical interfaces
• Round button actuator type matches original design
• Panel cutout dimensions accommodate standard 6.50mm circular mounting holes

Environmental & Compliance Criteria:

• RoHS3 compliance maintained for regulatory alignment
• Operating temperature range supports original thermal specifications
• Epoxy sealed terminals provide equivalent environmental protection

The MBN15SS1W03-BF represents an active product from the same manufacturer, offering functional equivalence while addressing the obsolescence of the original MB2011SS1W03-BF component.

Parameter Comparison

Engineering Selection Recommendations

The MBN15SS1W03-BF is suitable as a substitute for the obsolete MB2011SS1W03-BF based on electrical and functional equivalence. Both components maintain SPDT circuit configuration, identical current and voltage ratings, and compatible termination methods. Both parts are RoHS3 compliant and operate within the same temperature range.

The primary distinction is the mounting classification: the original part specifies Panel Mount, Rear configuration, while the substitute is classified as Bushing Mount. This difference requires mechanical evaluation during integration to ensure compatibility with existing panel cutout geometry and mounting hardware. The circular 6.50mm panel cutout dimension and round button actuator design support direct mechanical substitution in most applications.

The active product status of MBN15SS1W03-BF ensures ongoing availability and supply chain continuity, addressing the obsolescence constraint of the original component.

Frequently Asked Questions (FAQ)

Q: What makes MBN15SS1W03-BF electrically equivalent to MB2011SS1W03-BF?

A: Both components share identical SPDT circuit configuration, 6A AC / 3A DC current ratings, 125V AC / 30V DC voltage ratings, and PC pin termination. These parameters define the electrical interface and load-carrying capability required for direct functional substitution.

Q: Are there mechanical differences between these parts?

A: The primary mechanical difference is the mounting classification: Panel Mount, Rear versus Bushing Mount. Both use round button actuators and support the same 6.50mm circular panel cutout. Bushing mount configuration typically accommodates panel thicknesses within standard ranges. Verification of panel thickness and mounting hardware compatibility is necessary during integration.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both MB2011SS1W03-BF and MBN15SS1W03-BF are RoHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory standards.

Q: Why is the original part obsolete?

A: Product obsolescence is determined by manufacturer discontinuation. The MB2011SS1W03-BF has been discontinued by NKK Switches. The MBN15SS1W03-BF, classified as an active product, represents the current equivalent offering.

Q: Can MBN15SS1W03-BF be used as a direct drop-in replacement?

A: Electrical and functional compatibility is confirmed. Mechanical compatibility depends on existing panel mounting hardware and cutout specifications. The bushing mount design requires verification against the original panel mount configuration to ensure proper fit and retention.

Q: What is the inventory status of these parts?

A: MB2011SS1W03-BF: 829 pieces available (obsolete stock). MBN15SS1W03-BF: 735 pieces available (active product).
