Substitute Part Grouping Explanation

Substitution eligibility for the MB2011SS1W03-BC is determined by strict alignment with the following electrical and mechanical parameters:

Critical Substitution Criteria:

• Circuit configuration must be SPDT
• Current rating must support minimum 6A at 125V AC and 3A at 30V DC
• Mounting type must be panel mount, rear installation
• Actuator type must be round button configuration
• Termination style must be PC pin
• Operating temperature range must encompass -30°C to 85°C
• Mechanical life must meet or exceed 100,000 cycles
• Electrical life must meet or exceed 25,000 cycles

The substitute part MBN15SS1W03-BC is classified as a miniature pushbutton switch variant within the NKK Switches product family. Substitution assessment requires verification that all electrical ratings, mechanical specifications, and environmental performance parameters align with or exceed the original component specifications.

Parameter Comparison

Engineering Selection Recommendations

The MB2011SS1W03-BC is classified as obsolete, necessitating component replacement for new procurement and long-term system support. The MBN15SS1W03-BC is listed as an active product from the same manufacturer, indicating ongoing availability and manufacturing support.

Selection of MBN15SS1W03-BC as a substitute requires confirmation that all unspecified electrical and mechanical parameters meet or exceed the original component requirements. The active product status of MBN15SS1W03-BC provides assurance of continued supply chain availability and manufacturing consistency compared to the obsolete MB2011SS1W03-BC.

Both components are manufactured by NKK Switches, supporting design continuity within the same product family. Compliance verification with ROHS3 and other applicable regulatory standards should be confirmed for the substitute part prior to final selection.

Frequently Asked Questions (FAQ)

Q: What makes MBN15SS1W03-BC a potential substitute for MB2011SS1W03-BC?

A: Both components are manufactured by NKK Switches and share the same base part number suffix (SS1W03-BC), indicating alignment in core electrical and mechanical design. The substitute is classified as a miniature variant within the same product family.

Q: Why is the MB2011SS1W03-BC being phased out?

A: The MB2011SS1W03-BC is listed as obsolete, indicating that NKK Switches has discontinued manufacturing. The active status of MBN15SS1W03-BC suggests this variant represents the current product line continuation.
