Key Parameters

Substitute Part Grouping Explanation

The EB2011G-BE can be substituted with the 1977737-2 (TE Connectivity ALCOSWITCH Switches) based on the following critical parameters:

Substitution Criteria:

• Circuit configuration: Both are SPDT switches
• Switch function: Both operate as On-Mom (momentary)
• Mounting type: Both are panel mount with rear termination
• Termination style: Both use solder lug connections
• Electrical life: Both rated for 50,000 cycles
• Compliance: Both are ROHS3 compliant with EAR99 classification

Allowable Parameter Variations:

• Current rating: EB2011G-BE rated 0.4VA; 1977737-2 rated 60mA DC (0.06VA). The substitute operates at lower current capacity.
• Voltage rating: EB2011G-BE rated 28V AC/DC; 1977737-2 rated 30V DC. The substitute supports higher DC voltage.
• Operating temperature: EB2011G-BE operates -10°C to 70°C; 1977737-2 operates -20°C to 80°C. The substitute has wider temperature range.

Parameter Comparison

Engineering Selection Recommendations

EB2011G-BE Selection: Use the original EB2011G-BE when AC voltage switching at 28V is required, as the substitute part does not specify AC voltage capability. The EB2011G-BE is suitable for applications requiring 0.4VA current capacity at rated voltage.

1977737-2 Selection: The 1977737-2 is suitable as a substitute for DC-only applications operating at 30V or lower. This part is appropriate when current requirements do not exceed 60mA. The extended operating temperature range (-20°C to 80°C) makes this substitute preferable for applications with wider temperature extremes. Both parts maintain ROHS3 compliance and identical electrical life ratings, ensuring regulatory and reliability equivalence within their respective operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the 1977737-2 replace the EB2011G-BE in all applications?

A: No. The 1977737-2 is limited to DC operation at 30V maximum with 60mA current capacity. Use it only in DC circuits where current does not exceed 60mA. The original EB2011G-BE must be used for AC voltage applications or when current requirements exceed 60mA.

Q: What are the key differences between these two switches?

A: The primary differences are current rating (0.4VA vs. 60mA), AC voltage support (28V AC available only on EB2011G-BE), and operating temperature range (-10°C to 70°C vs. -20°C to 80°C). Both maintain identical circuit configuration (SPDT), switch function (On-Mom), mounting type, termination style, and electrical life.

Q: Are both parts RoHS compliant?

A: Yes. Both the EB2011G-BE and 1977737-2 are ROHS3 compliant with MSL rating of 1 (Unlimited) and EAR99 export classification.

Q: What is the panel cutout dimension for the 1977737-2?

A: The panel cutout dimension for the 1977737-2 is not specified in the available data. The EB2011G-BE requires a circular 6.35mm diameter cutout. Verify mechanical compatibility before substitution.

Q: Do both switches have the same electrical life rating?

A: Yes. Both the EB2011G-BE and 1977737-2 are rated for 50,000 electrical cycles, ensuring equivalent reliability in switching applications.
