Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB2011SB1G01-BA is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Circuit configuration (SPDT)
• Switch function (On-Momentary operation)
• Current rating (0.4VA minimum)
• Voltage rating (28V AC/DC minimum)

Mechanical Compatibility Criteria:

• Mounting type (Panel Mount, Rear)
• Actuator type (Round, Button)
• Termination style (Solder Lug)
• Panel cutout dimensions (Circular 12.50mm Dia)
• Operating temperature range (-30°C to 85°C)

Regulatory & Environmental Criteria:

• RoHS3 compliance
• Moisture sensitivity level (MSL 1)

The substitute part MBN15SB1G01-BA is classified as a compatible alternative based on manufacturer designation and functional equivalence within the NKK Switches product portfolio.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the obsolete MB2011SB1G01-BA, the MBN15SB1G01-BA is the manufacturer-designated equivalent. The substitute part maintains electrical specifications (SPDT, On-Momentary, 0.4VA, 28V AC/DC) and mechanical compatibility (Panel Mount, Rear; Round Button; Solder Lug termination; 12.50mm circular panel cutout).

The primary advantage of transitioning to MBN15SB1G01-BA is active product status, ensuring ongoing availability and supply chain continuity. Both components are manufactured by NKK Switches, confirming design and performance alignment within the manufacturer's product ecosystem.

Compliance verification should confirm RoHS3 and MSL 1 status for the substitute part prior to implementation in new production or critical repair applications.

Frequently Asked Questions (FAQ)

Q: Can MBN15SB1G01-BA directly replace MB2011SB1G01-BA in existing designs?

A: Yes. Both components share identical electrical ratings (SPDT, On-Momentary, 0.4VA, 28V AC/DC), mechanical mounting (Panel Mount, Rear; 12.50mm circular cutout), and termination style (Solder Lug). Physical and functional compatibility is confirmed.

Q: Why is the MB2011SB1G01-BA obsolete?

A: Product obsolescence is determined by the manufacturer. The MBN15SB1G01-BA represents the active equivalent within NKK Switches' current product line.

Q: Are there differences in panel cutout dimensions between these parts?

A: Both components specify a circular 12.50mm diameter panel cutout, ensuring mechanical interchangeability in panel-mounted applications.

Q: What is the significance of MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements, suitable for standard storage and handling conditions.

Q: Should RoHS3 compliance be verified for the substitute part?

A: Yes. While the main part is ROHS3 compliant, RoHS3 status for MBN15SB1G01-BA should be confirmed through the manufacturer's current documentation prior to use in regulated applications.
