Key Parameters

Substitute Part Grouping Explanation

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

Primary Compatibility Criteria:

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

Substitute Parts Identified:

MBN15SS1W01-BA (NKK Switches) – Manufacturer-recommended direct substitute. Maintains identical electrical specifications and mounting configuration within the NKK Switches product family.

MPA106F (TE Connectivity ALCOSWITCH Switches) – Cross-manufacturer equivalent. Meets or exceeds all primary electrical parameters with 6A AC / 4A DC rating at 125V AC / 28V DC. Panel cutout diameter of 6.35mm requires verification for mechanical fit in existing panel designs.

MPE106F (TE Connectivity ALCOSWITCH Switches) – Cross-manufacturer equivalent with enhanced ingress protection (Splash Proof). Electrical specifications identical to MPA106F. Panel cutout diameter of 6.35mm requires verification for mechanical fit in existing panel designs.

Parameter Comparison

Engineering Selection Recommendations

MBN15SS1W01-BA is the preferred substitute for direct replacement applications. As an active product from the original manufacturer NKK Switches, it maintains full compatibility with existing designs while ensuring continued supply chain access and technical support. ROHS3 compliance and MSL 1 rating align with the original component specifications.

MPA106F and MPE106F serve as cross-manufacturer alternatives when NKK Switches products are unavailable. Both TE Connectivity ALCOSWITCH options exceed the original electrical specifications with 4A DC capability versus 3A DC, and provide extended electrical life of 50,000 cycles compared to 25,000 cycles. Panel cutout diameter reduction from 6.50mm to 6.35mm requires mechanical verification for existing panel installations. MPE106F provides additional environmental protection through splash-proof ingress rating, suitable for applications with moisture exposure requirements.

All substitute options maintain ROHS3 compliance and MSL 1 moisture sensitivity classification, ensuring regulatory and environmental compatibility with the original MB2011SS1W01-BA specification.

Frequently Asked Questions (FAQ)

Q: Can MBN15SS1W01-BA be used as a direct drop-in replacement for MB2011SS1W01-BA?

A: MBN15SS1W01-BA is the manufacturer-recommended substitute from NKK Switches. However, the mounting type differs (bushing mount versus panel mount rear). Mechanical compatibility must be verified against your specific panel installation requirements before implementation.

Q: What is the primary difference between MPA106F and MPE106F?

A: Both parts share identical electrical specifications (6A AC / 4A DC at 125V AC / 28V DC) and mechanical dimensions. MPE106F includes splash-proof ingress protection, making it suitable for applications with moisture or liquid exposure. MPA106F lacks specified ingress protection and is appropriate for standard dry environments.

Q: Will the 6.35mm panel cutout diameter of TE Connectivity parts fit existing 6.50mm holes?

A: The 6.35mm cutout diameter is smaller than the original 6.50mm specification. Existing panel cutouts designed for 6.50mm diameter will accommodate the smaller TE Connectivity parts without modification. However, panel mounting tolerances and mechanical fit must be evaluated for your specific application.

Q: Are the TE Connectivity ALCOSWITCH parts (MPA106F, MPE106F) electrically compatible with the original MB2011SS1W01-BA?

A: Yes. Both TE Connectivity parts meet or exceed the electrical requirements: 6A AC / 4A DC (versus 3A DC original), 125V AC / 28V DC (versus 30V DC original), SPDT circuit, and On-Mom switch function. The higher DC current rating and lower DC voltage rating represent improved performance margins for most applications.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts (MBN15SS1W01-BA, MPA106F, MPE106F) maintain ROHS3 compliance. MBN15SS1W01-BA and both TE Connectivity parts carry MSL 1 (Unlimited) moisture sensitivity classification. REACH status varies: MBN15SS1W01-BA is REACH Unaffected, MPA106F is Vendor Undefined, and MPE106F is REACH Affecte
