Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB2011SB3W01-BA is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-Mom momentary operation)
• Current and voltage ratings (6A/125V AC minimum; 3A/30V DC minimum)
• Mounting type (Panel Mount, Rear)
• Actuator type (Round, Button)
• Termination style (Solder Lug)
• Ingress protection rating (IP67 minimum)
• Operating temperature range (-30°C to 85°C minimum)
• Mechanical and electrical life specifications

The identified substitute MBN15SB3W01-BA is classified as a compatible alternative based on manufacturer designation and shared electrical characteristics within the NKK Switches product family.

Parameter Comparison

Engineering Selection Recommendations

The MB2011SB3W01-BA is obsolete, necessitating substitute component identification for system continuity. The MBN15SB3W01-BA is designated by the manufacturer as the recommended substitute and carries active product status, ensuring ongoing availability and support.

The substitute part is manufactured by the same supplier (NKK Switches), reducing supply chain complexity and maintaining design consistency within the product family. Selection of the active substitute component provides access to current manufacturing processes and quality assurance protocols.

Verification of electrical and mechanical parameter equivalence with the original specification is required before implementation in production environments, particularly regarding current ratings, voltage ratings, and ingress protection characteristics.

Frequently Asked Questions (FAQ)

Q: Why is the MB2011SB3W01-BA obsolete? A: The MB2011SB3W01-BA is classified as obsolete by the manufacturer. The MBN15SB3W01-BA is the designated active replacement within the NKK Switches product portfolio.

Q: What are the critical parameters for substitution? A: Substitution requires equivalence in circuit configuration (SPDT), switch function (On-Mom), current ratings (6A AC / 3A DC minimum), voltage ratings (125V AC / 30V DC minimum), mounting type (Panel Mount, Rear), termination style (Solder Lug), and ingress protection (IP67).

Q: Is the substitute part available in the same packaging? A: The main part is packaged in standard format, while the substitute is available in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: What compliance certifications apply? A: The original MB2011SB3W01-BA is ROHS3 compliant and REACH unaffected. Compliance status of the substitute part should be confirmed with the manufacturer for specific application requirements.

Q: Are there any mechanical differences between the parts? A: Both components feature round button actuators and panel mount rear installation. Detailed mechanical drawings should be consulted to confirm dimensional compatibility with existing panel cutouts and mounting hardware.
