Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 7940116313 is determined by strict equivalence across the following critical parameters: current rating (9A), AC voltage rating (250V), DC voltage rating (80V), mounting configuration (DIN Rail), breaker classification (Thermal Magnetic), actuation mechanism (Push to Reset), pole count (1), and regulatory compliance certifications (CSA C22.2 No 235, UL1077, VDE). Parts meeting all these criteria are classified as parametric equivalents and may be used interchangeably in applications designed for the original component. The substitute part 7940102186 satisfies all substitution criteria through identical electrical ratings and mechanical specifications.

Parameter Comparison
