MB2011LD1G01 Equivalent & Substitute Parts

Part Overview

The MB2011LD1G01 is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 0.4VA rating at 28V. This component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing applications and new designs. The switch is designed for panel mount rear installation with solder lug termination and epoxy sealed terminals for environmental protection.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MB2011LD1G01 are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Circuit configuration: SPDT
• Switch function: On-Mom (Momentary)
• Mounting type: Panel Mount, Rear
• Termination style: Solder Lug
• Actuator type: Plunger for Cap
• Voltage compatibility: Minimum 28V DC rating
• Current capacity: Minimum 0.4VA or equivalent amperage rating
• Mechanical life: Minimum 100,000 cycles
• Electrical life: Minimum 50,000 cycles
• RoHS3 compliance

Two substitute parts meet these criteria: EB2011G from NKK Switches (active product status) and 1977737-2 from TE Connectivity ALCOSWITCH Switches (active product status). Both maintain SPDT configuration, momentary function, panel mount rear installation, and solder lug termination required for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

EB2011G (NKK Switches): This substitute maintains the closest electrical and mechanical specifications to the MB2011LD1G01. Both parts are manufactured by NKK Switches, share identical SPDT configuration, momentary function, current rating (0.4VA AC/DC), voltage rating (28V AC/DC), mechanical life (100,000 cycles), and electrical life (50,000 cycles). The EB2011G is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating. The panel cutout dimension differs slightly (6.35mm versus 6.50mm), requiring panel modification assessment. This part is the primary equivalent for direct replacement applications.

1977737-2 (TE Connectivity ALCOSWITCH Switches): This substitute provides functional equivalence with SPDT configuration, momentary operation, panel mount rear installation, and solder lug termination. The current rating is specified as 60mA DC, which is lower than the 0.4VA rating of the main part. The DC voltage rating is 30V, exceeding the 28V requirement. Operating temperature range (-20°C to 80°C) is narrower than the main part (-30°C to 85°C). This part is currently in active production with ROHS3 compliance and unlimited moisture sensitivity rating. Selection of this substitute requires confirmation that the 60mA DC current rating is sufficient for the application.

Both substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity classification, ensuring regulatory and environmental compatibility with the obsolete MB2011LD1G01.

Frequently Asked Questions (FAQ)

Q: Can EB2011G be used as a direct replacement for MB2011LD1G01?

A: EB2011G meets all critical electrical and mechanical parameters: SPDT circuit, 0.4VA at 28V AC/DC, momentary function, panel mount rear installation, solder lug termination, 100,000 mechanical cycles, and 50,000 electrical cycles. The panel cutout dimension is 6.35mm versus 6.50mm on the original part, requiring assessment of panel hole compatibility. Both parts are ROHS3 compliant with unlimited moisture sensitivity rating.

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

A: The 1977737-2 maintains SPDT configuration, momentary function, and panel mount rear installation with solder lug termination. However, the current rating is specified as 60mA DC, which is lower than the 0.4VA (approximately 400mA at 28V) rating of the MB2011LD1G01. The operating temperature range (-20°C to 80°C) is narrower than the original part (-30°C to 85°C). This substitute is suitable only for applications where the 60mA DC current requirement is confirmed as adequate.

Q: Are there packaging differences between the substitute parts?

A: The MB2011LD1G01 is specified with standard packaging. EB2011G is supplied in bulk packaging. 1977737-2 is also supplied in bulk packaging. Packaging format does not affect electrical or mechanical performance for panel mount applications.

Q: Do all substitute parts meet compliance requirements?

A: Both EB2011G and 1977737-2 are ROHS3 compliant and carry unlimited moisture sensitivity level (MSL 1) classification, matching the compliance profile of the obsolete MB2011LD1G01. Both parts are classified as EAR99 for export control purposes.

Q: What is the primary difference between EB2011G and 1977737-2?

A: EB2011G is manufactured by NKK Switches (same manufacturer as the original part) and maintains identical electrical ratings (0.4VA at 28V AC/DC) and mechanical life specifications (100,000 cycles). 1977737-2 is manufactured by TE Connectivity and has a reduced current rating (60mA DC) with a narrower operating temperature range. EB2011G is the closer functional equivalent for most applications.
