MB2011LS1W03 Equivalent & Substitute Parts

Part Overview

The MB2011LS1W03 is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with a standard plunger actuator and panel mount rear installation. This component is rated for 6A at 125V AC and 3A at 30V DC, with mechanical life of 100,000 cycles and electrical life of 25,000 cycles. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, repair, and component sourcing in legacy applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete MB2011LS1W03 is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Circuit configuration (SPDT)
• Switch function (On-Mom momentary operation)
• Current ratings (6A AC / 3A DC minimum)
• Voltage ratings (125V AC / 30V DC minimum)

Mechanical Compatibility Criteria:

• Mounting type (Panel Mount, Rear)
• Actuator type (Plunger for Cap)
• Termination style (PC Pin)
• Panel cutout dimensions (Circular 6.50mm Dia)
• Operating temperature range (-30°C to 85°C)

Compliance & Lifecycle Criteria:

• RoHS3 compliance
• MSL rating (MSL 1 or equivalent)
• Product status (Active preferred for long-term availability)

The MBN15LS1W03 qualifies as a substitute based on manufacturer designation and shared electrical/mechanical parameters within the NKK Switches product family.

Parameter Comparison

Engineering Selection Recommendations

The MB2011LS1W03 is classified as obsolete, necessitating component substitution for new procurement and long-term system support. The MBN15LS1W03 is designated as the manufacturer-recommended substitute and maintains active product status, ensuring continued availability and supply chain reliability.

Both components meet ROHS3 compliance requirements and share identical electrical ratings (6A AC / 125V AC, 3A DC / 30V DC) and circuit configuration (SPDT, On-Mom). The primary distinction is mounting configuration: the main part specifies Panel Mount Rear, while the substitute uses Bushing Mount. This difference requires mechanical evaluation during integration to confirm panel cutout compatibility and installation feasibility within the target application.

Selection of the MBN15LS1W03 is supported by manufacturer recommendation, active product status, and full electrical parameter alignment with the obsolete MB2011LS1W03.

Frequently Asked Questions (FAQ)

Q: Can the MBN15LS1W03 directly replace the MB2011LS1W03 in existing applications?

A: Electrical compatibility is confirmed across all ratings and circuit configuration. However, the mounting type differs (Bushing Mount vs. Panel Mount Rear). Direct mechanical replacement requires verification that the bushing mount configuration accommodates the existing panel cutout and installation geometry.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitutes must maintain SPDT circuit configuration, On-Mom switch function, minimum 6A AC / 3A DC current ratings, and minimum 125V AC / 30V DC voltage ratings. The MBN15LS1W03 meets all electrical criteria.

Q: Why is the MB2011LS1W03 obsolete?

A: The product has reached end-of-life status. The manufacturer recommends the MBN15LS1W03 as the active replacement for new designs and ongoing component sourcing.

Q: Are there compliance differences between the main part and substitute?

A: Both components are ROHS3 compliant with MSL 1 rating, ensuring equivalent environmental and regulatory compliance.

Q: What should be verified before implementing the MBN15LS1W03 substitute?

A: Confirm that the bushing mount installation method is compatible with the target panel geometry and that the 6.50mm circular cutout dimension accommodates the substitute's mounting requirements.
