Substitute Part Grouping Explanation

Substitute parts for the MB2011LD3W01-CF are identified based on the following critical parameters that determine functional compatibility:

Mandatory Matching Parameters:

Circuit configuration: SPDT
Switch function: On-Mom (Momentary)
AC voltage rating: 125V minimum
AC current rating: 6A minimum
Mounting type: Panel Mount, Rear
Termination style: Solder Lug
Panel cutout diameter: Compatible circular configuration

Acceptable Variation Parameters:

DC current rating: Substitute parts may exceed the 3A DC specification
DC voltage rating: Substitute parts may exceed the 30V DC specification
Operating temperature range: Substitute parts may have narrower ranges if they encompass the primary operating conditions
Ingress protection: Substitute parts may exceed IP67 rating
Mechanical and electrical life cycles: Substitute parts may differ from specified values

The substitute parts MPA106F and MPE106F meet all mandatory matching parameters while maintaining electrical and mechanical compatibility with the MB2011LD3W01-CF.

Engineering Selection Recommendations

Both MPA106F and MPE106F are active product alternatives to the obsolete MB2011LD3W01-CF. Selection between these substitutes should be based on the following factors:

MPA106F (TE Connectivity ALCOSWITCH Switches):

Active product status ensures long-term availability and supply chain continuity
ROHS3 compliant with unlimited moisture sensitivity level
Electrical life rating of 50,000 cycles exceeds the original specification
Ingress protection rating not specified; suitable for standard indoor applications

MPE106F (TE Connectivity ALCOSWITCH Switches):

Active product status with established manufacturing support
ROHS3 compliant with unlimited moisture sensitivity level
Electrical life rating of 50,000 cycles exceeds the original specification
Splash Proof ingress protection provides enhanced environmental resistance compared to MPA106F
REACH Affected status requires compliance verification for specific end-use applications

Both substitutes maintain electrical compatibility with the original MB2011LD3W01-CF across AC voltage and current specifications. Panel cutout diameter differences (6.35mm vs. 6.50mm) require mechanical evaluation for panel mounting compatibility.

Frequently Asked Questions (FAQ)

Q: Can MPA106F or MPE106F directly replace MB2011LD3W01-CF in existing designs?

A: Both parts meet the mandatory electrical specifications (SPDT circuit, 6A AC at 125V, On-Mom function, solder lug termination). Panel cutout diameter differs by 0.15mm (6.35mm vs. 6.50mm), requiring mechanical assessment for panel mounting compatibility.

Q: What is the difference between MPA106F and MPE106F?

A: Both parts share identical electrical ratings and circuit configuration. MPE106F provides Splash Proof ingress protection, while MPA106F does not specify ingress protection. MPE106F is REACH Affected; MPA106F status is Vendor Undefined. Selection depends on environmental exposure requirements and regulatory compliance needs.

Q: Why is the MB2011LD3W01-CF obsolete?

A: Product status reflects NKK Switches' discontinuation of this model. Active alternatives from TE Connectivity ALCOSWITCH Switches (MPA106F and MPE106F) provide equivalent functionality with improved electrical life ratings and current product support.

Q: Are there temperature range differences between the original and substitute parts?

A: The MB2011LD3W01-CF operates from -30°C to 85°C. Both MPA106F and MPE106F operate from -20°C to 80°C. The substitute parts have a narrower range but maintain compatibility for most standard industrial and commercial applications within -20°C to 80°C.

Q: What packaging is available for the substitute parts?

A: Both MPA106F and MPE106F are supplied in Bulk packaging. The original MB2011LD3W01-CF was supplied with standard packaging.

Q: Are the substitute parts RoHS compliant?

A: Yes, both MPA106F and MPE106F are ROHS3 compliant, matching the compliance status of the original MB2011LD3W01-CF.
