Key Parameters

Substitute Part Grouping Explanation

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

Primary Compatibility Criteria:

• Circuit configuration: SPDT
• Switch function: On-Mom
• Mounting type: Panel Mount, Rear
• Termination style: Solder Lug
• Voltage rating compatibility: Substitute must meet or exceed 28V DC/AC rating
• Current rating compatibility: Substitute must handle 0.4VA or greater

Secondary Considerations:

• Operating temperature range overlap with -30°C to 85°C specification
• Electrical life rating of 50,000 cycles minimum
• RoHS3 compliance for regulatory alignment

The identified substitute parts meet these criteria with the following distinctions:

MB2011LS1G01 (NKK Switches): Identical electrical and mechanical specifications to the main part, differing only in actuator type (plunger for cap vs. standard configuration). Same manufacturer ensures design continuity.

1977737-2 (TE Connectivity ALCOSWITCH): Meets SPDT, On-Mom, panel mount rear, and solder lug requirements. Current rating of 60mA is lower than the main part's 0.4VA specification, and voltage rating is 30V DC only. Operating temperature range is -20°C to 80°C. Product status is active.

8168LHZBE2 (C&K): Meets SPDT, On-Mom, panel mount rear, and solder lug requirements. Current rating matches at 0.4VA. Voltage rating is 20V AC/DC, which is below the main part's 28V specification. Operating temperature range is -30°C to 65°C. Product status is active.

Parameter Comparison

Engineering Selection Recommendations

MB2011LS1G01 is the primary equivalent for direct replacement. It maintains identical electrical specifications (0.4VA at 28V AC/DC), mechanical life (100,000 cycles), operating temperature range (-30°C to 85°C), and RoHS3 compliance. Both parts are obsolete, indicating this option is suitable for legacy system maintenance where existing inventory or archived documentation references are available.

1977737-2 is a functional substitute for applications where current requirements do not exceed 60mA and voltage does not exceed 30V DC. The reduced operating temperature upper limit (80°C vs. 85°C) and absence of AC voltage rating require verification against system specifications. Active product status provides ongoing availability.

8168LHZBE2 is a functional substitute for applications where voltage requirements do not exceed 20V AC/DC and operating temperature does not exceed 65°C. The reduced voltage and temperature ratings represent significant derating from the main part specification. Active product status provides ongoing availability.

All substitute parts maintain SPDT circuit configuration, On-Mom function, panel mount rear mounting, solder lug termination, and 50,000 cycle electrical life rating.

Frequently Asked Questions (FAQ)

Q: Can MB2011LS1G01 be used as a direct replacement for MB2011SS1G01?

A: Yes. Both parts share identical electrical ratings (0.4VA at 28V AC/DC), mechanical specifications (100,000 cycle life), operating temperature range (-30°C to 85°C), and RoHS3 compliance. The difference in actuator type does not affect electrical performance.

Q: What are the limitations of using 1977737-2 as a substitute?

A: The 1977737-2 has a maximum current rating of 60mA, which is lower than the main part's 0.4VA specification. Voltage rating is 30V DC only, with no AC rating specified. Operating temperature maximum is 80°C versus 85°C for the main part. Applications must operate within these reduced parameters.

Q: What are the limitations of using 8168LHZBE2 as a substitute?

A: The 8168LHZBE2 has a maximum voltage rating of 20V AC/DC, which is below the main part's 28V specification. Operating temperature maximum is 65°C versus 85°C for the main part. Applications must operate within these reduced electrical and thermal parameters.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. MB2011SS1G01, MB2011LS1G01, 1977737-2, and 8168LHZBE2 are all ROHS3 compliant.

Q: Which substitute part has active product status?

A: Both 1977737-2 and 8168LHZBE2 have active product status. MB2011LS1G01 is obsolete, matching the main part status.

Q: Do all parts use the same termination style?

A: Yes. All parts use solder lug termination, ensuring compatibility with existing PCB layouts and assembly processes.

Q: What is the panel cutout dimension difference between parts?

A: MB2011SS1G01 and MB2011LS1G01 require a circular 6.50mm diameter cutout. 8168LHZBE2 requires a circular 6.35mm diameter cutout. 1977737-2 panel cutout dimensions are not specified in available data.
