Understanding the KEMET PEH200VO4220MU2 Before Selecting an Equivalent Capacitor
The KEMET PEH200VO4220MU2 is an aluminum electrolytic screw-terminal capacitor from KEMET’s PEH200 family, described as an 85°C screw-terminal aluminum electrolytic capacitor. It is supplied in box packaging, is RoHS3 compliant, REACH unaffected, active in product status, and classified under ECCN EAR99.
For replacement evaluation, the relevant characteristics are not limited to the catalog description. The PEH200VO4220MU2 should be assessed as a high-energy, high-ripple bulk capacitor used where low impedance, stable capacitance, and secure mechanical mounting are required.
| Evaluation Area | KEMET PEH200VO4220MU2 Consideration | Replacement Impact |
|---|---|---|
| Capacitor type | Aluminum electrolytic, screw-terminal construction | Alternatives should use the same capacitor technology unless the circuit is redesigned |
| Temperature class | 85°C operating class | A 105°C part may be acceptable if electrical and mechanical ratings match, but lifetime calculations must be reviewed |
| Termination | Screw terminals | Replacement must match terminal style, thread size, polarity marking, creepage distance, and busbar connection method |
| Electrical role | Bulk DC-link, smoothing, hold-up, pulse energy, or ripple filtering | Capacitance, voltage, ESR, ripple current, and surge rating affect converter stability and thermal rise |
| Compliance | RoHS3 compliant, REACH unaffected | Substitute parts should meet the same regulatory requirements for production continuity |
| Packaging and supply | Box packaging; new original stock available | Procurement should verify lead time, date code, storage conditions, and authenticity |
Typical applications include industrial drives, rectifier output filters, DC bus storage, UPS equipment, welding power supplies, renewable-energy converters, traction auxiliary supplies, and high-power test equipment. In these applications, a capacitor with the same nominal capacitance and voltage may still fail to qualify if it has lower ripple current capability, shorter endurance, different mounting dimensions, or unsuitable terminal spacing.
For the PEH200VO4220MU2 replacement process, the first engineering step is to confirm the original rated capacitance, rated voltage, tolerance, can diameter, can height, terminal spacing, screw thread, ripple current rating at the operating frequency, ESR, leakage current, and endurance rating from the official KEMET datasheet or existing approved drawing.

For low-risk substitution, choose the part that matches the original KEMET PEH200VO4220MU2 electrical rating first, then confirm ripple-current margin at the actual switching or rectifier ripple frequency. Mechanical checks should include can diameter, can height, terminal spacing, screw size, insulation clearance, vent orientation, clamp fit, and busbar stress. In high-power equipment, the replacement should also be reviewed for thermal rise under worst-case ripple current because aluminum electrolytic lifetime is closely tied to internal hot-spot temperature.
If the equipment is already qualified around the KEMET PEH200VO4220MU2, the KEMET ALS30A222KF400 may be the easiest same-brand alternative to evaluate. The Cornell Dubilier 380LX222M400A052 and 500C222M400BB2B are practical candidates where CDE screw-terminal capacitors are accepted in the platform. The TDK EPCOS B43564A4228M000 is often suitable for industrial DC-link applications, while Nichicon LLS2G222MELC and United Chemi-Con U36D401LG222M76X130HP can support second-source strategies when the mechanical envelope and ripple ratings align.
