Substitute Part Grouping Explanation

Substitution eligibility for the UKA1E331MPD1TD is determined by strict equivalence across the following parameters:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 25 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package configuration: Radial, Can (exact match required)
• Physical dimensions: 0.315" diameter, 0.512" height, 0.138" lead spacing (exact match required)
• Mounting type: Through Hole (exact match required)
• Polarization: Polar (exact match required)
• Operating temperature range: -55°C ~ 105°C (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The UPA1E331MPD1TD qualifies as a direct substitute based on full alignment with all critical electrical and mechanical parameters. Additional advantages include extended lifetime rating and active product status.

Parameter Comparison
