Substitute Part Grouping Explanation

Substitute parts for the PT5L7LB2 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic requires matching the following parameters without deviation:

Coil voltage specification (12VDC)
Contact form configuration (4PDT / 4 Form C)
Contact current rating (6 A)
Maximum switching voltage (240VAC)
DIN rail mounting compatibility
Coil current draw (62.5 mA)
Coil resistance (192 Ohms)
Operating temperature range (-40°C to 70°C)
Contact material composition (Silver Nickel)
Screw terminal termination
RoHS3 compliance status

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. The PT5L7LB2 and its identified substitute share identical electrical performance characteristics and mechanical interface requirements, permitting interchangeable use in applications designed for either part number.
