Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011SS2G45-BA is determined by the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (momentary on-off operation)
• Electrical ratings (0.4VA at 28V AC/DC)
• Mounting type (through-hole, right-angle, vertical orientation)
• Termination style (PC pin)
• Actuator type (round button)
• Operating temperature range (-30°C to 85°C)
• Mechanical and electrical life specifications

The identified substitute part MBN15SS2G45-BA shares the core electrical and mechanical characteristics required for functional equivalence in applications currently using the MB2011SS2G45-BA.

Parameter Comparison

Engineering Selection Recommendations

The MB2011SS2G45-BA is classified as obsolete. The substitute part MBN15SS2G45-BA is manufactured by the same supplier (NKK Switches) and maintains active product status, ensuring continued availability and supply chain reliability. Both components share identical electrical specifications (SPDT, 0.4VA, 28V AC/DC) and mechanical characteristics (through-hole right-angle vertical mounting, PC pin termination, round button actuator).

Selection of MBN15SS2G45-BA as a substitute is based on functional equivalence across all specified parameters. The active status of the substitute part provides superior long-term availability compared to the obsolete main part number.

Frequently Asked Questions (FAQ)

Q: What makes MBN15SS2G45-BA a valid substitute for MB2011SS2G45-BA?

A: Both parts share identical circuit configuration (SPDT), electrical ratings (0.4VA at 28V AC/DC), mounting type (through-hole right-angle vertical), termination style (PC pin), and actuator type (round button). These parameters define functional equivalence for pushbutton switch applications.

Q: Are there any differences in packaging between the main part and substitute?

A: The main part MB2011SS2G45-BA is packaged in standard format, while MBN15SS2G45-BA is supplied in bulk packaging. Both are suitable for component-level integration.

Q: Does the substitute part meet the same compliance standards?

A: The main part MB2011SS2G45-BA is ROHS3 compliant. Compliance status for MBN15SS2G45-BA is not specified in the provided data and should be verified through the manufacturer's current documentation.

Q: Why is the main part obsolete?

A: Product obsolescence is determined by the manufacturer. The active status of MBN15SS2G45-BA indicates that NKK Switches continues to support this functional category through current product offerings.

Q: Can MBN15SS2G45-BA be used as a direct replacement in existing designs?

A: Yes, provided that the application requirements align with the specified electrical ratings (0.4VA at 28V AC/DC), operating temperature range (-30°C to 85°C), and mechanical life expectations (100,000 cycles minimum). Physical mounting and termination compatibility must be confirmed for the specific PCB layout.
