Key Parameters

Substitute Part Grouping Explanation

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

Primary Compatibility Criteria:

• Circuit configuration: SPDT
• Switch function: On-Mom (momentary action)
• Current rating: Minimum 6A AC
• Voltage rating: Minimum 125V AC
• Mounting type: Panel Mount, Rear
• Termination style: Solder Lug
• Panel cutout diameter: Compatible with 6.35mm to 6.50mm range

Identified Substitute Parts:

MBN15SS1W01-CF (NKK Switches) qualifies as a manufacturer-recommended substitute, maintaining the same electrical specifications and termination methodology within the NKK Switches product family.

MPA106F and MPE106F (TE Connectivity ALCOSWITCH Switches) qualify as functionally equivalent substitutes. Both parts maintain SPDT circuit configuration, 6A AC / 4A DC current ratings, 125V AC / 28V DC voltage ratings, panel mount rear configuration, and solder lug termination. The panel cutout diameter of 6.35mm is compatible with standard 6.50mm mounting holes through standard panel adapter practices.

Parameter Comparison

Engineering Selection Recommendations

MBN15SS1W01-CF is the primary substitute option, as it is the manufacturer-recommended equivalent from NKK Switches. This part maintains active product status and ROHS3 compliance. Selection of this part eliminates any cross-manufacturer compatibility considerations.

MPA106F and MPE106F are functionally equivalent alternatives from TE Connectivity ALCOSWITCH Switches. Both parts are active products with ROHS3 compliance. MPA106F carries vendor-undefined REACH status, while MPE106F is REACH Affected. Both parts exceed the electrical life specification of the original component (50,000 cycles versus 25,000 cycles) and support the required current and voltage ratings. MPE106F provides additional ingress protection rated as Splash Proof, suitable for applications requiring enhanced environmental resistance.

All substitute parts maintain EAR99 ECCN classification and HTSUS code 8536.50.9035, consistent with the original component.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts maintain identical SPDT circuit configuration, momentary switch function, 6A AC current rating, and 125V AC voltage rating. The DC current rating is higher (4A versus 3A), and DC voltage rating is slightly lower (28V versus 30V). Both parts are suitable for applications within the original component's electrical specifications.

Q: What is the difference between MPA106F and MPE106F?

A: Both parts share identical electrical specifications and mounting configuration. MPE106F includes Splash Proof ingress protection, making it suitable for applications requiring environmental resistance. MPA106F does not specify ingress protection. MPE106F carries REACH Affected status, while MPA106F status is vendor-undefined.

Q: Is the 6.35mm panel cutout diameter of MPA106F and MPE106F compatible with the 6.50mm cutout of the original part?

A: The 6.35mm cutout diameter is smaller than the 6.50mm original specification. Standard panel adapter bushings accommodate this difference for retrofit applications. New designs should specify the appropriate cutout diameter during panel fabrication.

Q: What is the significance of the higher electrical life rating in the substitute parts?

A: MPA106F and MPE106F specify 50,000 electrical cycles, compared to 25,000 cycles for MB2011SS1W01-CF. This indicates extended operational life under switching conditions and provides additional design margin for applications with high cycle counts.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. MB2011SS1W01-CF, MBN15SS1W01-CF, MPA106F, and MPE106F are all ROHS3 compliant, ensuring compatibility with RoHS3 regulated applications and supply chains.

Q: What is the operating temperature difference between the original and substitute parts?

A: MB2011SS1W01-CF operates from -30°C to 85°C. MPA106F and MPE106F operate from -20°C to 80°C. Applications requiring operation below -20°C or above 80°C should retain the original component or verify alternative solutions.
