Key Parameters

Substitute Part Grouping Explanation

Substitution of the E2011 is determined by the following critical parameters:

Mechanical Compatibility:

• Circuit configuration (SPST)
• Mounting type (Panel Mount)
• Panel cutout dimensions (Circular - 6.50mm Dia)
• Actuator type and length (Standard Round, 10.50mm)
• Termination style (Solder Lug)

Electrical Compatibility:

• Voltage rating requirements (minimum 28V AC/DC)
• Current handling capacity (minimum 0.4VA)
• Switch function (On-Off operation)

The substitute part M2011SS1W01/UC shares identical mechanical specifications and mounting interface with the E2011, enabling direct physical replacement in panel mount applications. Both components feature the same actuator geometry, panel cutout dimensions, and solder lug termination, ensuring compatibility with existing mechanical assemblies and PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

The M2011SS1W01/UC provides functional equivalence to the E2011 for applications requiring SPST toggle switch operation with panel mount installation. The substitute part exceeds the electrical requirements of the original component, with higher voltage and current ratings (125V AC, 30V DC, 6A AC, 4A DC) compared to the E2011 specification (28V AC/DC, 0.4VA). This increased electrical capacity ensures compatibility with the original application while providing margin for circuit variations.

The M2011SS1W01/UC features ROHS3 compliance, addressing regulatory requirements that the original E2011 does not meet. Both components share identical mechanical interfaces, including panel cutout dimensions, actuator geometry, and termination style, enabling direct substitution in existing assemblies.

The extended operating temperature range of the M2011SS1W01/UC (-30°C ~ 85°C) exceeds the E2011 specification (-10°C ~ 70°C), providing broader environmental compatibility. The substitute part includes epoxy sealed terminals, enhancing environmental protection compared to the original component.

Frequently Asked Questions (FAQ)

Q: Can the M2011SS1W01/UC directly replace the E2011 in existing applications?

A: Yes. Both components share identical mechanical specifications including panel cutout dimensions (Circular - 6.50mm Dia), actuator type and length (Standard Round, 10.50mm), and termination style (Solder Lug). Physical installation and electrical connection are compatible without modification.

Q: What are the key electrical differences between these parts?

A: The M2011SS1W01/UC has higher electrical ratings than the E2011. The substitute supports 125V AC and 30V DC with 6A AC and 4A DC current capacity, compared to the E2011's 28V AC/DC at 0.4VA. Applications operating at the E2011's original voltage and current levels operate well within the M2011SS1W01/UC's electrical envelope.

Q: Are there compliance differences between the E2011 and M2011SS1W01/UC?

A: Yes. The M2011SS1W01/UC is ROHS3 compliant, while the E2011 is RoHS non-compliant. Both are REACH unaffected and classified under ECCN EAR99. For applications subject to RoHS requirements, the M2011SS1W01/UC meets current regulatory standards.

Q: What is the difference in electrical life between these components?

A: The E2011 is rated for 50,000 electrical cycles, while the M2011SS1W01/UC is rated for 25,000 cycles. For applications requiring extended cycle life, the E2011 specification is superior. However, both components meet typical industrial switch application requirements.

Q: How do the operating temperature ranges compare?

A: The M2011SS1W01/UC operates across -30°C ~ 85°C, exceeding the E2011 range of -10°C ~ 70°C. The substitute part provides broader environmental compatibility for applications exposed to wider temperature variations.

Q: What packaging is available for the M2011SS1W01/UC?

A: The M2011SS1W01/UC is supplied in bulk packaging, compared to the E2011 which uses standard packaging. Verify packaging requirements for your procurement and assembly processes.
