Substitute Part Grouping Explanation

The substitute part 1977737-2 (TE Connectivity ALCOSWITCH Switches) qualifies as an equivalent based on the following critical parameters:

Circuit configuration match: Both parts are SPDT switches with on-momentary function, enabling identical electrical switching behavior in the circuit.

Voltage compatibility: The substitute operates at 30V DC, which exceeds the 28V requirement of the main part, providing adequate voltage margin for direct substitution.

Current rating consideration: The substitute is rated at 60mA DC, which is lower than the 0.4VA specification of the main part. This substitution is valid only for applications where the actual circuit current does not exceed 60mA.

Mounting and termination: Both parts feature panel mount rear installation with solder lug termination, ensuring mechanical and electrical interface compatibility.

Electrical life specification: Both parts are rated for 50,000 cycles, meeting the same operational durability requirement.

Compliance alignment: Both parts are ROHS3 compliant and classified as EAR99, maintaining regulatory consistency.

Parameter Comparison

Engineering Selection Recommendations

Both the EB2011G-BF and 1977737-2 maintain ROHS3 compliance and EAR99 classification, ensuring regulatory consistency for applications subject to these requirements. The substitute part 1977737-2 operates across a wider temperature range (-20°C to 80°C versus -10°C to 70°C), providing extended environmental capability.

Selection between these parts depends on circuit current requirements. The EB2011G-BF supports 0.4VA operation, while the 1977737-2 is limited to 60mA DC. For applications operating below 60mA, the substitute provides equivalent functionality. For applications requiring higher current capacity, the main part EB2011G-BF is the appropriate selection.

Both parts are active products with confirmed inventory availability and identical electrical life specifications of 50,000 cycles.

Frequently Asked Questions (FAQ)

Q: Can 1977737-2 directly replace EB2011G-BF in all applications?

A: Direct replacement is valid only when circuit current does not exceed 60mA. The substitute is rated for 60mA DC maximum, while the main part supports 0.4VA. Verify actual circuit current before substitution.

Q: Are the panel mount dimensions compatible between these parts?

A: Both parts are specified for panel mount rear installation with solder lug termination. Panel cutout dimensions for 1977737-2 are not provided in the specification. Confirm mechanical fit with the panel assembly before final selection.

Q: What is the voltage margin for using 1977737-2 at 28V?

A: The substitute is rated for 30V DC, providing a 2V margin above the 28V requirement. This margin is within acceptable engineering practice for DC applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both EB2011G-BF and 1977737-2 are ROHS3 compliant and classified as EAR99. Regulatory requirements are equivalent for both parts.

Q: Which part has better temperature performance?

A: The 1977737-2 operates across -20°C to 80°C, compared to -10°C to 70°C for the EB2011G-BF. The substitute provides 10°C additional margin at both temperature extremes.
