Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EB2011P-CG is determined by strict equivalence across the following critical parameters: SPDT circuit configuration, 3A AC current rating, 125V AC voltage rating, momentary on-off function, panel mount rear installation, PC pin termination, and 25,000 cycle electrical life minimum. The substitute part 1977740-2 (TE Connectivity ALCOSWITCH Switches) meets all mandatory electrical and mechanical criteria. Both parts maintain identical circuit topology, current handling capacity, voltage specification, and switching function. Termination style and mounting configuration are identical. Electrical life ratings are equivalent at the specified 25,000 cycles. Both components carry active product status and ROHS3 compliance certification, confirming ongoing manufacturing support and regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

Both EB2011P-CG and 1977740-2 are active products with confirmed ROHS3 compliance and EAR99 export classification.
