Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011SS1G01-CC is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration must be SPDT
• Switch function must be On-Mom (momentary operation)
• Mounting type must be Panel Mount, Rear
• Termination style must be Solder Lug
• Electrical life rating must meet or exceed 50,000 cycles

Secondary Compatibility Criteria:

• Current rating must accommodate the application load (0.4VA baseline)
• Voltage rating must equal or exceed 28V DC
• Operating temperature range must encompass the application environment
• RoHS3 compliance required for regulatory alignment

The substitute part 1977737-2 satisfies all primary criteria and maintains regulatory compliance, making it functionally equivalent for direct replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The 1977737-2 from TE Connectivity ALCOSWITCH Switches series qualifies as a functional equivalent for the obsolete MB2011SS1G01-CC based on matching circuit topology, switch function, mounting configuration, and termination method. Both components maintain ROHS3 compliance and identical electrical life ratings.

Selection of the 1977737-2 requires verification of the following application-specific constraints:

• Application current draw must not exceed 60mA DC, as the substitute is rated lower than the original 0.4VA specification
• Operating environment minimum temperature must remain above -20°C, as the substitute's lower temperature limit is -20°C versus the original -30°C
• Actuator form factor difference (plunger versus round button) must be evaluated for panel interface compatibility and user interaction requirements

The substitute part is currently in active production status, ensuring supply chain availability and long-term procurement viability compared to the obsolete original component.

Frequently Asked Questions (FAQ)

Q: Can the 1977737-2 directly replace the MB2011SS1G01-CC in all applications?

A: Direct replacement is possible only when application current draw does not exceed 60mA DC and minimum operating temperature remains above -20°C. The different actuator form factor (plunger versus round button) may require panel interface modification.

Q: What is the primary reason for substitution?

A: The MB2011SS1G01-CC is classified as obsolete. The 1977737-2 provides equivalent electrical and mechanical functionality while maintaining active production status and regulatory compliance.

Q: Are both components RoHS compliant?

A: Yes, both the MB2011SS1G01-CC and 1977737-2 are ROHS3 compliant, ensuring regulatory alignment for applications requiring RoHS certification.

Q: How do the current ratings compare?

A: The original component is rated 0.4VA (AC/DC), while the substitute is rated 60mA DC. Applications requiring AC operation or current levels exceeding 60mA DC require alternative evaluation.

Q: What packaging format is the substitute available in?

A: The 1977737-2 is supplied in bulk packaging, differing from the original component's packaging specification.

Q: Are the electrical life ratings equivalent?

A: Yes, both components specify 50,000 cycles electrical life, providing equivalent operational durability for switching applications.
