MB2011SS1A01-CA Equivalent & Substitute Parts

Part Overview

The MB2011SS1A01-CA is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 6A AC / 3A DC current rating and 125V AC / 30V DC voltage rating. This component is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain electrical performance within specified parameters while offering current product status and supply availability.

Key Parameters

Substitute Part Grouping Explanation

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

• Circuit Type: SPDT configuration required
• Switch Function: On-Momentary operation required
• AC Current Rating: Minimum 6A at 125V AC
• DC Current Rating: Minimum 3A at 30V DC
• Mounting Configuration: Panel Mount, Rear orientation required
• Termination: Solder Lug termination required
• Panel Cutout Compatibility: Circular aperture within acceptable tolerance range

The identified substitute parts (MPA106F and MPE106F) satisfy the primary electrical and mechanical requirements. Both alternatives provide SPDT circuit configuration, On-Momentary function, 6A AC rating at 125V, and rear panel mount termination. Variations in DC current rating (4A vs. 3A), DC voltage rating (28V vs. 30V), panel cutout diameter (6.35mm vs. 6.50mm), and operating temperature range represent acceptable engineering trade-offs within the scope of component substitution.

Parameter Comparison

Engineering Selection Recommendations

Both MPA106F and MPE106F are qualified substitutes for the obsolete MB2011SS1A01-CA based on electrical and mechanical compatibility. Selection between the two TE Connectivity alternatives should consider the following factors:

MPA106F provides standard functionality with active product status and ROHS3 compliance. REACH status is listed as Vendor Undefined, requiring clarification from the manufacturer for applications subject to REACH regulations.

MPE106F offers identical electrical specifications to MPA106F with the addition of Splash Proof ingress protection and confirmed REACH Affected status. This alternative is suitable for applications requiring enhanced environmental protection and explicit REACH compliance documentation.

Both substitutes exceed the original part's electrical life specification (50,000 cycles vs. 25,000 cycles), providing improved reliability margins. The panel cutout diameter reduction from 6.50mm to 6.35mm requires mechanical verification for existing panel designs. Operating temperature range narrowing from -30°C to 85°C to -20°C to 80°C should be evaluated against application requirements.

Frequently Asked Questions (FAQ)

Q: Can MPA106F or MPE106F be used as direct replacements for MB2011SS1A01-CA?

A: Both parts satisfy the primary electrical requirements (SPDT circuit, 6A AC at 125V, On-Momentary function, solder lug termination, rear panel mount). Panel cutout diameter differs by 0.15mm (6.35mm vs. 6.50mm), requiring mechanical fit verification. Operating temperature range is narrower by 5°C at each extreme.

Q: What is the difference between MPA106F and MPE106F?

A: Both parts share identical electrical specifications. MPE106F includes Splash Proof ingress protection and REACH Affected compliance status, while MPA106F has standard protection and Vendor Undefined REACH status. Selection depends on environmental exposure requirements and regulatory compliance obligations.

Q: Are there compatibility concerns with the panel cutout diameter difference?

A: The substitute parts require a 6.35mm circular aperture versus the original 6.50mm specification. Existing panel designs with 6.50mm cutouts may require mechanical modification or use of adapter hardware. New designs should accommodate the 6.35mm requirement.

Q: Do the substitute parts meet RoHS and environmental compliance requirements?

A: Both MPA106F and MPE106F are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. MPE106F carries REACH Affected status with documented compliance. MPA106F REACH status requires vendor confirmation for applications subject to REACH regulations.

Q: How do the electrical life ratings compare?

A: The substitute parts provide 50,000 electrical cycles versus 25,000 cycles for the original MB2011SS1A01-CA, representing a 2x improvement in rated cycle life and enhanced reliability margins for equivalent applications.

Q: What is the impact of the DC voltage rating reduction from 30V to 28V?

A: Applications operating at DC voltages between 28V and 30V require evaluation. For circuits operating below 28V DC, the substitute parts are fully compatible. Circuits requiring operation above 28V DC are not suitable for these alternatives.
