MB2011SS1W01-CG Equivalent & Substitute Parts

Part Overview

The MB2011SS1W01-CG is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 6A AC / 3A DC current rating at 125V AC / 30V DC. This panel mount, rear termination switch utilizes solder lug connections and epoxy sealed terminals for reliable operation across -30°C to 85°C. The product is classified as obsolete, necessitating identification of functionally equivalent active alternatives to maintain design continuity and ensure supply chain availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011SS1W01-CG is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: SPDT
• Switch function: On-Mom
• Current rating: Minimum 6A AC
• Voltage rating: Minimum 125V AC
• Mounting type: Panel Mount, Rear
• Termination style: Solder Lug
• Panel cutout diameter: Compatible with 6.50mm specification

Substitute Classification:

MBN15SS1W01-CG (NKK Switches) qualifies as the manufacturer-recommended substitute, maintaining NKK Switches lineage with equivalent electrical and mechanical specifications.

MPA106F and MPE106F (TE Connectivity ALCOSWITCH Switches) qualify as similar substitutes, meeting all primary electrical parameters with panel cutout diameter of 6.35mm, representing a 0.15mm reduction requiring verification of mechanical fit within existing panel apertures.

Parameter Comparison

Engineering Selection Recommendations

MBN15SS1W01-CG is the primary substitute option. As an active product from the original manufacturer NKK Switches, it maintains design continuity and carries ROHS3 compliance certification. Selection of this part eliminates mechanical fit uncertainty and preserves supply chain relationships with the original equipment manufacturer.

MPA106F and MPE106F serve as secondary alternatives from TE Connectivity ALCOSWITCH Switches. Both parts meet electrical specifications with 6A AC / 4A DC ratings at 125V AC / 28V DC and provide extended electrical life of 50,000 cycles. The 0.15mm reduction in panel cutout diameter (6.35mm versus 6.50mm) requires mechanical verification for existing panel apertures. MPE106F provides additional splash proof ingress protection and carries REACH Affected certification, whereas MPA106F status is vendor undefined. Both alternatives maintain ROHS3 compliance and active product status.

Frequently Asked Questions (FAQ)

Q: Can MPA106F or MPE106F be used as direct replacements for MB2011SS1W01-CG?

A: Both parts satisfy the electrical requirements: SPDT circuit, On-Mom function, 6A AC / 4A DC current rating, and 125V AC / 28V DC voltage rating. The panel cutout diameter difference of 0.15mm (6.35mm versus 6.50mm) requires mechanical evaluation. If the existing panel aperture is sized precisely to 6.50mm, the smaller diameter may result in loose fit. Verify mechanical clearance and mounting stability before implementation.

Q: What is the difference between MPA106F and MPE106F?

A: Both parts share identical electrical specifications and operating parameters. MPE106F includes splash proof ingress protection, providing enhanced environmental sealing. MPE106F carries REACH Affected certification, while MPA106F status is vendor undefined. Selection between these parts depends on environmental exposure requirements and regulatory compliance obligations.

Q: Why is MBN15SS1W01-CG recommended as the primary substitute?

A: MBN15SS1W01-CG is the manufacturer-recommended alternative from NKK Switches, the original equipment manufacturer. This selection eliminates mechanical fit uncertainty, maintains design continuity, and preserves established supply chain relationships. The part carries active product status and ROHS3 compliance.

Q: Are there temperature range differences between the original part and substitutes?

A: The MB2011SS1W01-CG operates across -30°C to 85°C. MPA106F and MPE106F operate across -20°C to 80°C, representing a narrower range. Applications requiring operation below -20°C or above 80°C must retain the original part or verify alternative solutions. MBN15SS1W01-CG temperature specifications are not provided in available data.

Q: What is the electrical life difference?

A: MB2011SS1W01-CG is rated for 25,000 electrical cycles. MPA106F and MPE106F are rated for 50,000 electrical cycles, providing double the operational life. This represents an improvement in component longevity for high-cycle applications.

Q: Are all substitute parts RoHS compliant?

A: All listed parts carry ROHS3 compliance certification, meeting current regulatory requirements for hazardous substance restrictions.
