Substitute Part Grouping Explanation

Substitute selection for terminal blocks is strictly determined by matching the number of circuits, wire entry count, pitch, number of rows, current and voltage ratings, wire gauge range, termination types, barrier style, mounting configuration, operating temperature rating, insulation material and flammability class, and compliance designations (RoHS, REACH, MSL). Model CDM-37 from Curtis Industries is grouped as a direct substitute based on identical specifications across all critical attributes.
