Parameter Comparison

Engineering Selection Recommendations

Both the MLP442M050EK0D and MLP442M050EK1D are Active products from Cornell Dubilier Electronics in the MLP series. The parts are electrically and mechanically identical across all specified parameters. Selection between these two part numbers is based on availability and inventory status:

• MLP442M050EK0D: 1034 units in stock
• MLP442M050EK1D: 1151 units in stock

Both parts share identical compliance status:

• RoHS non-compliant
• REACH Affected
• ECCN: EAR99
• HTSUS: 8532.22.0055
• Moisture Sensitivity Level: 1 (Unlimited)

For applications requiring 4400 µF aluminum electrolytic capacitors at 50 V with FlatPack, tabbed chassis-mount configuration, either part number provides equivalent performance. Selection may be determined by procurement lead times, supplier availability, or project-specific inventory requirements.

Frequently Asked Questions (FAQ)

Q: Can MLP442M050EK1D be used as a direct replacement for MLP442M050EK0D?

A: Yes. The MLP442M050EK1D is a parametric equivalent with identical electrical and mechanical specifications.
