Frequently Asked Questions (FAQ)

Q: Can I substitute a 250 V rated capacitor for the 200 V 226CKS200MLQ?

A: Yes. A higher voltage rating is electrically compatible in applications designed for 200 V operation. The 250 V rated parts (250BXC22MEFC10X16, 250PX22MEFC10X16, EKXJ251ELL220MJ16S, UCY2E220MPD) meet all mechanical and electrical substitution criteria. Verify circuit board layout accommodates the potential height increase (18.00mm vs. 17.50mm for some models).

Q: What is the difference between ESR and Impedance specifications?

A: ESR (Equivalent Series Resistance) is measured at a specific frequency (120 Hz in this case). Impedance is a broader measure of total opposition to current flow. The MAL215262229E3 lists Impedance (3.2 Ohms) rather than ESR; these are related but not directly comparable measurements. Consult manufacturer datasheets for precise frequency-dependent performance characteristics.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 Compliant status, consistent with the original 226CKS200MLQ.

Q: Which substitute parts are suitable for automotive applications?

A: The following parts carry AEC-Q200 automotive qualification: MAL215262229E3 (200 V), 200RX3022M10X16 (200 V), and EKXJ251ELL220MJ16S (250 V). These parts are qualified for automotive-grade reliability and extended temperature operation.

Q: What is the maximum height difference among substitute parts?

A: The original 226CKS200MLQ has a seated height of 17.50mm. Some substitute parts (200CFX22MEFC10X16, 200RX3022M10X16, 250BXC22MEFC10X16, 250PX22MEFC10X16) have a maximum seated height of 18.00mm, representing a 0.50mm increase. Verify circuit board layout and component clearance before substitution.

Q: Which substitute offers the longest operational lifetime?

A: The UCY2E220MPD (Nichicon UCY series) provides the longest lifetime rating at 12000 Hrs @ 105°C, compared to the original part's 2000 Hrs @ 85°C.

Q: Can I use a substitute with a lower ripple current rating?

A: No. Ripple current rating must meet or exceed the application requirement. Substitutes with lower ripple current ratings (such as 250PX22MEFC10X16 at 105 mA @ 120 Hz) are suitable only for applications with lower ripple current demands than the original 175 mA @ 120 Hz specification.

Q: What is the REACH status of all substitute parts?

A: Most substitute parts are REACH Unaffected. The UCY2E220MPD (Nichicon) is listed as REACH Affected. Verify compliance requirements for your specific application and regulatory jurisdiction.
