Substitute Part Grouping Explanation

Substitution of aluminum electrolytic capacitors is determined by strict equivalence across electrical and mechanical parameters. The MLP331M300EA1A has one identified substitute: MLP331M300EA0A.

Substitution is valid when the following parameters are identical:

Capacitance value: 330 µF
Rated voltage: 300 V
Tolerance: ±20%
ESR @ 120 Hz: 399 mOhm
Lifetime @ 85°C: 2000 Hrs
Operating temperature range: -40°C to 85°C
Ripple current specifications (120 Hz and 20 kHz)
Lead spacing: 1.000" (25.40 mm)
Physical dimensions: 2.000" L × 1.750" W (50.80 mm × 44.45 mm)
Height - Seated (Max): 0.500" (12.70 mm)
Package configuration: FlatPack, Tabbed
Mounting type: Chassis Mount
Polarization: Polar

The substitute part MLP331M300EA0A meets all these criteria and is therefore electrically and mechanically interchangeable with the primary part number.

Engineering Selection Recommendations

Both MLP331M300EA1A and MLP331M300EA0A are active products from Cornell Dubilier Electronics with identical electrical and mechanical specifications. Selection between these part numbers should be based on inventory availability and procurement lead times.

Both parts share the same compliance profile:

RoHS non-compliant status
REACH Affected designation
EAR99 export classification
HTSUS code 8532.22.0055
Moisture Sensitivity Level 1 (Unlimited)

The MLP331M300EA0A currently has higher inventory availability (1097 units versus 974 units), which may support shorter procurement cycles. Both parts are suitable for general-purpose high-voltage filtering and energy storage applications requiring 330 µF capacitance at 300 V with FlatPack, tabbed chassis mount configuration.
