Key Parameters

Substitute Part Grouping Explanation

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

Primary Compatibility Criteria:

• Circuit configuration must be SPDT
• Switch function must be On-Mom (momentary)
• Termination style must be Solder Lug
• Mounting type must be Panel Mount, Rear
• Current rating must support 0.4VA minimum
• Voltage rating must support 28V minimum (AC and/or DC)
• Panel cutout diameter must accommodate 6.50mm circular opening or smaller

Secondary Considerations:

• Operating temperature range must encompass or exceed -30°C to 85°C
• Electrical life must meet or exceed 50,000 cycles
• RoHS3 compliance required for regulatory alignment

Three substitute parts meet these criteria with varying degrees of parameter alignment and product availability status.

Parameter Comparison

Engineering Selection Recommendations

MB2411E1G01-FA (NKK Switches MB2400 Series)

This substitute provides the closest electrical and mechanical alignment with the main part. Both components share identical voltage ratings (28V AC/DC), current capacity (0.4VA), panel cutout dimensions (6.50mm), and operating temperature range (-30°C to 85°C). The MB2411E1G01-FA offers enhanced electrical life (100,000 cycles versus 50,000 cycles) and maintains ROHS3 compliance. Both parts are classified as obsolete, indicating similar market lifecycle status. This substitute is suitable for direct replacement in applications where the enhanced cycle life provides additional margin.

1977737-2 (TE Connectivity ALCOSWITCH Blue Series)

This substitute meets core substitution criteria with SPDT configuration, On-Mom function, and solder lug termination. The part maintains 50,000 electrical life cycles and ROHS3 compliance. However, the current rating is limited to 60mA DC, which is below the 0.4VA (approximately 400mA at 28V) requirement of the main part. The DC voltage rating of 30V exceeds the 28V requirement, but AC voltage rating is not specified. Operating temperature range (-20°C to 80°C) does not extend to the lower -30°C limit. This part is classified as active, providing superior long-term availability. Selection of this substitute requires confirmation that the 60mA current limitation is acceptable for the application circuit.

8168LHZBE2 (C&K 8060 Series)

This substitute provides SPDT configuration, On-Mom function, and matching current capacity (0.4VA AC/DC) with solder lug termination. The part is classified as active, ensuring ongoing availability. However, voltage ratings are limited to 20V AC/DC, which is below the 28V requirement. Panel cutout diameter is 6.35mm, requiring mechanical redesign of the panel opening. Operating temperature range (-30°C to 65°C) does not extend to the upper 85°C limit. REACH status is listed as affected, introducing potential regulatory considerations. This substitute is suitable only for applications operating below 20V and 65°C maximum temperature.

Frequently Asked Questions (FAQ)

Q: Can MB2411E1G01-FA be used as a direct replacement for MB2011SS1G01-CA?

A: Yes. Both parts share identical electrical ratings (0.4VA, 28V AC/DC), circuit configuration (SPDT), switch function (On-Mom), termination style (solder lug), mounting type (panel mount rear), and panel cutout dimensions (6.50mm circular). Operating temperature ranges are identical (-30°C to 85°C). The MB2411E1G01-FA provides superior electrical life (100,000 versus 50,000 cycles). No mechanical or electrical redesign is required.

Q: Is 1977737-2 compatible with the MB2011SS1G01-CA application?

A: Compatibility depends on circuit current requirements. The 1977737-2 is rated for 60mA DC maximum, while the MB2011SS1G01-CA is rated for 0.4VA (approximately 400mA at 28V). If the application circuit draws less than 60mA, this substitute is electrically compatible. The operating temperature range (-20°C to 80°C) does not reach the lower -30°C specification. Verification of actual circuit current draw is required before selection.

Q: What are the mechanical constraints when considering 8168LHZBE2?

A: The 8168LHZBE2 requires a 6.35mm circular panel cutout, compared to the 6.50mm requirement of the main part. This represents a 0.15mm reduction in diameter. Panel drilling or modification may be necessary. Additionally, voltage ratings (20V AC/DC) are below the 28V specification, and operating temperature range does not extend to 85°C maximum. This substitute is not recommended for direct replacement without application-specific verification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. MB2411E1G01-FA, 1977737-2, and 8168LHZBE2 are all ROHS3 compliant, matching the compliance status of the main part MB2011SS1G01-CA.

Q: Which substitute offers the best long-term availability?

A: Both 1977737-2 and 8168LHZBE2 are classified as active products, ensuring ongoing manufacturer support and availability. MB2411E1G01-FA is classified as obsolete, similar to the main part. For applications requiring extended procurement windows, selection of an active substitute is recommended.

Q: What is the significance of the panel cutout diameter specification?

A: Panel cutout diameter determines mechanical compatibility with existing panel installations. The main part requires a 6.50mm circular opening. MB2411E1G01-FA matches this specification exactly. The 8168LHZBE2 requires 6.35mm, necessitating panel modification. The 1977737-2 does not specify panel cutout dimensions, requiring verification with the manufacturer before installation.
