MB2011SS1A01 Equivalent & Substitute Parts

Part Overview

The MB2011SS1A01 is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 6A AC and 3A DC current ratings at 125V AC and 30V DC respectively. This component is panel-mounted with rear termination using solder lugs and is rated for 100,000 mechanical cycles and 25,000 electrical cycles. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011SS1A01 is determined by the following critical parameters:

Mandatory Matching Criteria:

• Circuit configuration: SPDT
• AC current rating: 6A minimum
• AC voltage rating: 125V minimum
• Mounting type: Panel Mount, Rear
• Termination style: Solder Lug
• RoHS compliance: ROHS3 Compliant

Allowable Variations:

• DC current rating may exceed 3A (higher ratings are acceptable)
• DC voltage rating may exceed 30V (higher ratings are acceptable)
• Panel cutout diameter: 6.35mm is acceptable as a minor dimensional variation for rear-mounted panel applications
• Operating temperature range may be narrower than the original specification
• Electrical and mechanical life ratings may differ based on manufacturer specifications

The substitute parts MPA106F and MPE106F meet all mandatory criteria while maintaining functional equivalence for standard pushbutton switch applications.

Parameter Comparison

Engineering Selection Recommendations

Both MPA106F and MPE106F are active production components from TE Connectivity ALCOSWITCH Switches and provide direct functional substitution for the obsolete MB2011SS1A01.

MPA106F Selection Criteria:

• Active product status with established supply chain
• Meets all electrical specifications with 4A DC rating exceeding the original 3A requirement
• ROHS3 compliant with unlimited moisture sensitivity level
• Suitable for applications where splash protection is not required

MPE106F Selection Criteria:

• Active product status with established supply chain
• Meets all electrical specifications with 4A DC rating exceeding the original 3A requirement
• ROHS3 compliant with unlimited moisture sensitivity level
• Includes splash proof ingress protection, providing enhanced environmental durability
• REACH Affected status requires compliance verification in regulated applications

Both substitutes provide superior electrical life ratings (50,000 cycles versus 25,000 cycles), enhancing component reliability in cyclic switching applications. Panel cutout diameter variation from 6.50mm to 6.35mm requires mechanical panel assessment for mounting compatibility.

Frequently Asked Questions (FAQ)

Q: Can MPA106F and MPE106F be used interchangeably with MB2011SS1A01?

A: Both parts meet the mandatory electrical and mechanical specifications for substitution. The primary difference is that MPE106F includes splash proof ingress protection, while MPA106F does not. Selection depends on environmental exposure requirements.

Q: What is the impact of the panel cutout diameter difference (6.50mm vs 6.35mm)?

A: The 0.15mm reduction in cutout diameter for substitute parts requires mechanical panel assessment. Existing panel holes sized for 6.50mm may require modification or use of adapter hardware for proper mounting of MPA106F or MPE106F components.

Q: Are the substitute parts suitable for DC applications?

A: Yes. Both MPA106F and MPE106F are rated for 4A DC at 28V, exceeding the original MB2011SS1A01 specification of 3A DC at 30V. DC applications are fully supported.

Q: What is the significance of the electrical life rating increase from 25,000 to 50,000 cycles?

A: The substitute parts provide double the electrical life specification, indicating enhanced contact durability and extended component service life in repetitive switching applications.

Q: Does REACH Affected status on MPE106F affect component selection?

A: REACH Affected status indicates the component contains substances of concern under REACH regulations. Compliance requirements depend on application jurisdiction and end-use classification. Regulatory assessment is required for applications subject to REACH enforcement.

Q: Are both substitute parts RoHS3 compliant?

A: Yes. Both MPA106F and MPE106F are ROHS3 compliant, matching the compliance status of the original MB2011SS1A01.
