Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

Direct Equivalents (Identical Specifications):

Capacitance: 1 µF
Voltage Rating: 50 V
Tolerance: ±10%
Package / Case: Axial
Physical Dimensions: 0.110" Dia x 0.290" L
Operating Temperature Range: -55°C ~ 125°C
Mounting Type: Through Hole
RoHS3 Compliance

Upgrade Category (Enhanced Tolerance):

All parameters identical to direct equivalents except tolerance specification of ±5% (tighter tolerance than original ±10%)

Parts meeting these criteria are classified as direct substitutes or upgrades. No deviations from specified electrical or mechanical parameters are permitted for substitution classification.
