The Vishay Beyschlag MKT1820322634W is a metallized polyester film capacitor delivering 0.022 µF capacitance with ±5% tolerance, rated for 630V DC and 220V AC operation. Constructed from metallized polyester dielectric, this radial through-hole component combines reliable performance across a -55°C to 125°C operating temperature range with a compact 13.00mm × 5.50mm × 10.50mm package footprint and 10.00mm lead spacing suitable for standard PCB layouts.
As part of the MKT1820 series, this film capacitor leverages metallized polyester construction to provide self-healing capability and stable electrical characteristics under varying temperature conditions. The 630V DC voltage rating positions it for power electronics applications where voltage margin and long-term reliability matter, while the 0.022 µF value fits filtering and energy storage functions in DC link and DC filtering circuits. The ±5% tolerance maintains predictable capacitance behavior across production lots, supporting consistent circuit performance in high-voltage switching supplies, motor drives, and industrial power conversion equipment.
The radial through-hole mounting format with PC pin termination facilitates automated insertion processes and offers mechanical stability in applications subject to vibration or thermal cycling. The 10.00mm lead spacing aligns with standard through-hole footprints, simplifying board layout and enabling direct substitution in existing designs. Metallized polyester dielectric material provides a balance of volumetric efficiency and temperature stability, with the extended -55°C to 125°C operating range covering automotive-grade and industrial environments without derating concerns.
Designed for DC link and DC filtering applications, the MKT1820322634W addresses ripple current suppression, voltage smoothing, and energy buffering in switched-mode power supplies, inverter circuits, and DC bus architectures. The 630V DC rating accommodates peak voltage transients in rectified mains or high-voltage DC systems, while the film construction maintains low dissipation factor and high insulation resistance over extended operating life. RoHS3 compliance and MSL 1 classification simplify procurement and storage, with tape and reel packaging supporting high-volume assembly operations.

A reliable MKT1820322634W replacement should be checked against the original PCB footprint, required AC/DC voltage stress, pulse current exposure, thermal environment, and expected lifetime. In filtering applications, a part that is electrically acceptable may still require layout review if the body size, height, or lead pitch differs from the original Vishay MKT1820 device.
Understanding Vishay MKT1820322634W Before Selecting an Equivalent Capacitor
The Vishay Beyschlag/Draloric/BC Components MKT1820322634W is a 0.022 µF metallized polyester film capacitor from the MKT1820 series. It has ±5% capacitance tolerance, 630 VDC rating, 220 VAC rating, radial through-hole mounting, and 10.00 mm lead spacing. Its body size is approximately 13.00 mm x 5.50 mm with a seated height of 10.50 mm.
| Specification | Vishay MKT1820322634W Engineering Relevance |
|---|---|
| Capacitance | 0.022 µF; replacement should maintain the same nominal value to preserve filter cutoff frequency, timing behavior, and impedance profile |
| Tolerance | ±5%; tighter or equal tolerance is preferred when the capacitor affects signal filtering, resonance, or timing accuracy |
| Voltage rating | 630 VDC / 220 VAC; alternatives should meet or exceed the actual circuit stress, including derating margin |
| Dielectric | Metallized polyester; replacements using similar MKT polyester technology usually provide comparable size, self-healing behavior, and general-purpose filtering performance |
| Temperature range | -55°C to +125°C; lower-rated substitutes may be unsuitable near power components or enclosed assemblies |
| Mounting | Through-hole radial, PC pins; mechanical compatibility depends strongly on lead spacing, body width, and seated height |
| Lead spacing | 10.00 mm; closest drop-in candidates should match this pitch or allow safe lead forming |
| Applications | DC link and DC filtering; replacement evaluation should include ripple, pulse stress, insulation resistance, and long-term thermal loading |
The original part is not a high-capacitance power DC-link capacitor; it is better understood as a small-value film capacitor used for filtering, coupling, suppression support, or localized DC bus noise control. Because it uses metallized polyester rather than polypropylene, it typically offers compact size and economical performance, but polypropylene alternatives may be chosen when lower dissipation factor or higher pulse endurance is needed.
Candidate Equivalent Parts for MKT1820322634W Replacement Evaluation
The following alternatives are suitable candidates for engineering comparison with Vishay MKT1820322634W. Final approval should be based on the latest manufacturer datasheet, footprint check, and operating conditions.

Engineering Comparison of MKT1820322634W Replacement Options
Replacement selection should balance electrical equivalence with manufacturability and sourcing risk. A substitute that matches capacitance and voltage may still introduce issues if the lead spacing, body height, dielectric losses, or tolerance differ from the original Vishay MKT1820322634W.
| Engineering Factor | Panasonic ECQE6223JF | Cornell Dubilier 223MWR630K | TDK EPCOS B32529C0223J000 | WIMA MKS4C032203F00KSSD |
|---|---|---|---|---|
| Electrical compatibility | Strong match when verified as 0.022 µF, ±5%, 630 VDC polyester film | Good voltage and capacitance match, but ±10% tolerance may shift filter response | Strong candidate if the selected ordering code confirms the required 630 VDC rating | Good capacitance and voltage-class match; suitable for many high-voltage polyester film uses |
| Mechanical compatibility | Often close to compact radial polyester formats, but lead pitch must be checked | Radial package; may need lead forming depending on pitch and body size | Radial EPCOS package options vary by series code, so footprint confirmation is needed | Box-style package can be mechanically larger; check height, width, and neighboring component clearance |
| Performance differences | Similar dielectric behavior to original MKT polyester capacitor | Similar general-purpose behavior, with looser capacitance control | Comparable MKT technology; may offer strong consistency in industrial supply chains | Mechanically robust construction; may provide favorable stability in demanding PCB environments |
| Reliability considerations | Suitable if genuine stock and correct series voltage are confirmed | Acceptable for general filtering; tolerance must not affect circuit margin | Suitable for production use after voltage and pulse ratings are reviewed | Good option for industrial assemblies where package size is acceptable |
| Package availability | Availability may depend on regional stock and lifecycle status | Often available through industrial capacitor channels | Broad EPCOS/TDK distribution, but exact suffix availability varies | Commonly sourced in multiple lead styles and tolerances, depending on distributor stock |
| Cost considerations | Usually competitive for general-purpose film replacement | May be cost-effective when ±10% tolerance is acceptable | Often balanced between cost and recognized industrial supply | May cost more than compact dipped alternatives depending on package and availability |
| Best-fit scenarios | Closest electrical-style replacement for ±5% polyester designs | Cost-sensitive filtering where tolerance is flexible | Designs requiring an EPCOS/TDK qualified alternative | Industrial equipment where a box-style WIMA MKS4 capacitor fits the PCB |
| Main limitation | Lifecycle and package confirmation | Tolerance is not equal to the original ±5% rating | Ordering-code verification is needed to avoid wrong voltage or pitch | Possible size mismatch versus Vishay MKT1820 footprint |
For a near-equivalent MKT1820322634W replacement, Panasonic ECQE6223JF is often the most direct candidate if availability and footprint are acceptable. TDK EPCOS
