Substitute Part Grouping Explanation
Substitute parts for the MB2011SS4W01/U are qualified based on the following critical parameters:
- Circuit configuration: SPDT
- Switch function: On-Mom
- Current rating: Minimum 6A AC capability
- Voltage rating: Minimum 125V AC and 28V DC or higher
- Mounting type: Panel Mount, Rear
- Actuator type: Plunger for Cap
- Termination style: Solder Lug
- Panel cutout dimensions: Compatible circular mounting (6.35mm or 6.50mm)
- Compliance: ROHS3 Compliant
The identified substitutes MPA106F and MPE106F from TE Connectivity ALCOSWITCH Switches meet these electrical and mechanical criteria. Both parts maintain SPDT configuration, On-Mom function, 6A AC current rating, 125V AC voltage rating, plunger actuator, solder lug termination, and ROHS3 compliance. Minor variations in DC current rating (4A versus 3A), DC voltage rating (28V versus 30V), operating temperature range, and panel cutout diameter (6.35mm versus 6.50mm) are within acceptable substitution parameters for this component category.

Engineering Selection Recommendations
Both MPA106F and MPE106F are active product alternatives to the obsolete MB2011SS4W01/U. Selection between these substitutes is determined by application requirements:
MPA106F is suitable for standard applications requiring SPDT pushbutton switch functionality with 6A AC and 4A DC ratings at 125V AC and 28V DC. This part maintains full ROHS3 compliance and provides extended electrical life of 50,000 cycles compared to the original 25,000 cycles.
MPE106F provides identical electrical specifications to MPA106F with the addition of splash proof ingress protection, making it appropriate for applications requiring environmental protection. This part carries REACH Affected status and maintains ROHS3 compliance.
Both substitutes accommodate the original panel cutout dimension with minor tolerance consideration (6.35mm versus 6.50mm), and both operate within a narrower temperature range (-20°C to 80°C) compared to the original part (-30°C to 85°C). DC voltage rating is reduced from 30V to 28V, which remains suitable for most standard applications.
Frequently Asked Questions (FAQ)
Q: Can MPA106F and MPE106F be used interchangeably with MB2011SS4W01/U?
A: Both parts meet the core electrical and mechanical substitution criteria for SPDT pushbutton switch applications. The primary differences are panel cutout diameter (6.35mm versus 6.50mm), operating temperature range (-20°C to 80°C versus -30°C to 85°C), and DC voltage rating (28V versus 30V). Application-specific requirements determine suitability.
Q: What is the difference between MPA106F and MPE106F?
A: Both parts share identical electrical specifications and SPDT configuration. MPE106F includes splash proof ingress protection, making it suitable for applications requiring environmental protection. MPE106F carries REACH Affected status, while MPA106F status is vendor undefined.
Q: Does the panel cutout dimension difference affect installation?
A: The substitute parts require a 6.35mm circular cutout compared to the original 6.50mm. Panel modifications may be necessary for direct mechanical replacement in existing designs.
Q: Are the substitute parts RoHS compliant?
A: Both MPA106F and MPE106F are ROHS3 compliant, matching the compliance status of the original MB2011SS4W01/U.
Q: What is the electrical life difference between the original and substitute parts?
A: The MB2011SS4W01/U is rated for 25,000 electrical cycles, while both MPA106F and MPE106F are rated for 50,000 electrical cycles, providing extended operational life.
Q: Can these substitutes operate at the original part's temperature extremes?
A: The substitute parts operate within -20°C to 80°C, which is narrower than the original -30°C to 85°C range. Applications requiring operation below -20°C or above 80°C require evaluation against specific design requirements.
