Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LLG2G331MELZ45 is determined by strict equivalence across the following parameters:

Electrical specifications: Capacitance value (330 µF), rated voltage (400 V), and tolerance (±20%) must be identical. Polarization must remain polar.

Mechanical compatibility: Package type (Radial, Can - Snap-In), lead spacing (10.00 mm), external diameter (22.00 mm), and seated height (47.00 mm) must match exactly to ensure PCB footprint compatibility.

Mounting configuration: Through-hole mounting type is required.

Compliance and regulatory status: RoHS3 compliance and REACH unaffected status must be maintained.

The LGL2G331MELZ45 meets all substitution criteria. Both parts are manufactured by Nichicon, share identical electrical and mechanical specifications, and maintain equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the LLG2G331MELZ45 and LGL2G331MELZ45 are Active products with full RoHS3 compliance and REACH unaffected status. The LGL2G331MELZ45 offers extended temperature operation to 105°C with corresponding lifetime rating at that temperature, compared to the LLG2G331MELZ45 rated to 85°C. Selection between these parts depends on application thermal requirements. Both parts satisfy identical electrical and mechanical interface requirements and are suitable for direct substitution in through-hole PCB designs requiring 330 µF, 400 V polarized capacitive elements.
