Substitute Part Grouping Explanation

Substitution eligibility for the DCP4I045006DD2KSSD is determined by the following critical parameters:

Mandatory Matching Parameters:

Capacitance value: 5 µF
Dielectric material: Polypropylene (PP), Metallized
Tolerance: ±10%
Mounting type: Through Hole
Package type: Radial
Lead spacing: 27.50 mm
Termination: PC Pins
Operating temperature range: -55°C to 105°C
AEC-Q200 automotive rating

Allowable Variation Parameters:

Voltage Rating - DC: Equal to or greater than 600V
ESR: Equal to or lower than the original specification

The DCP4L045006DD2KSSD qualifies as a parametric equivalent because it maintains all mandatory matching parameters while providing a higher voltage rating (800V) and lower ESR (14.6 mOhms versus 22 mOhms), both of which are acceptable variations for substitution in applications designed for the original 600V part.
