Key Parameters

Substitute Part Grouping Explanation

Substitution within the MLP331M400EB0C product family is determined by the following critical parameters:

Capacitance Value: 330 µF (fixed across all substitutes)

Tolerance: ±20% (fixed across all substitutes)

Voltage Rating: The primary differentiator. The MLP331M420EB0C provides a higher voltage rating of 420 V, compared to the 400 V rating of the main part. This higher voltage rating permits direct substitution in applications designed for 400 V operation, as the component maintains backward compatibility with lower voltage requirements.

Electrical Characteristics: ESR, ripple current ratings, and thermal lifetime specifications remain identical across substitute parts, ensuring equivalent performance in ripple current handling and thermal management.

Physical Form Factor: Lead spacing, dimensions, height, and FlatPack package configuration are identical, ensuring mechanical compatibility and PCB layout interchangeability.

Mounting Configuration: Through-hole mounting type and lead spacing of 1.000" (25.40 mm) are consistent across all parts in this substitution group.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution Criteria:

The MLP331M420EB0C is a direct substitute for the MLP331M400EB0C in applications where the circuit design operates at or below 400 V. The higher voltage rating of 420 V provides additional voltage margin without altering electrical performance characteristics. Both parts maintain identical capacitance, tolerance, ESR, ripple current ratings, thermal lifetime, and physical form factor.

Compliance Alignment:

Both the main part and substitute maintain identical regulatory and compliance status: RoHS non-compliant, REACH Affected, ECCN EAR99, and HTSUS 8532.22.0085. Moisture sensitivity level remains at MSL 1 (Unlimited) for both components, indicating no moisture-related handling restrictions.

Product Status:

Both parts maintain Active product status, confirming ongoing manufacturing support and availability. Inventory levels support component procurement, with 879 units of the MLP331M400EB0C and 797 units of the MLP331M420EB0C currently in stock.

Selection Logic:

Component selection between these parts should be based on circuit voltage requirements and inventory availability. The MLP331M420EB0C is suitable for designs requiring enhanced voltage margin or where higher-rated components are preferred for reliability considerations. The MLP331M400EB0C remains appropriate for applications with strict voltage specifications at 400 V.
