Case Diameter: 0.984" (25.00 mm) (exact match required)
Height: 1.457" (37.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Polarization: Polar (exact match required)

Allowable Variation Parameters:

Voltage Rating: May be equal to or higher than 200 V
Lifetime @ 105°C: May be equal to or higher than 2000 Hrs
Ripple Current: May vary based on voltage and series rating
Manufacturer: Alternative manufacturers permitted if all mandatory parameters match

The substitute parts listed below maintain all mandatory compatibility parameters while offering variations in voltage rating and/or lifetime specifications that are suitable for direct replacement in the LKX2D561MESA35 application.

Engineering Selection Recommendations

All listed substitute parts maintain full compatibility with the LKX2D561MESA35 footprint and mounting requirements. Selection among substitutes is based on the following criteria:

Direct Replacement (Same Voltage, Same Lifetime): No exact equivalent exists with identical 200 V / 2000 Hrs specifications from the provided substitute list.

Same Voltage, Extended Lifetime: LGR2D561MELA35 (Nichicon) provides 200 V rating with 10000 Hrs lifetime, offering improved reliability for the same voltage class.

Higher Voltage Rating, Same Lifetime: LGG2E561MELA35 (Nichicon) and 381LQ561M250J032 (CDE) both provide 250 V rating with 2000 Hrs lifetime, suitable for applications requiring voltage margin.

Higher Voltage Rating, Extended Lifetime: LGN2P561MELA35 (Nichicon) provides 220 V rating with 3000 Hrs lifetime. 381LR561M250J032 (CDE) provides 250 V rating with 3000 Hrs lifetime.

All substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance status of the original component.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage rated capacitor as a substitute? A: Yes. A capacitor rated for higher voltage (220 V or 250 V) is a valid substitute for the 200 V LKX2D561MESA35, provided all other parameters including capacitance, tolerance, package dimensions, and lead spacing remain identical.

Q: Does extended lifetime affect compatibility? A: No. A capacitor with extended lifetime (3000 Hrs or 10000 Hrs) is fully compatible with the LKX2D561MESA35 application. Extended lifetime represents improved performance and reliability.

Q: Are Nichicon and Cornell Dubilier Electronics (CDE) parts interchangeable? A: Yes, provided all electrical and mechanical parameters match exactly. Both manufacturers' parts listed meet the same dimensional, electrical, and compliance requirements.

Q: What parameters must remain unchanged for substitution? A: Capacitance (560 µF), tolerance (±20%), lead spacing (10.00 mm), case diameter (25.00 mm), height (37.00 mm), package type (Radial, Can - Snap-In), and mounting type (Through Hole) must remain identical.

Q: Can I substitute a part with lower voltage rating? A: No. The substitute must have a voltage rating equal to or higher than 200 V. Lower voltage ratings are not acceptable.

Q: Are all listed parts currently in stock? A: Inventory status is provided for reference. LKX2D561MESA35 has 725 units, LGR2D561MELA35 has 1231 units, LGN2P561MELA35 has 907 units, LGG2E561MELA35 has 666 units, 381LR561M250J032 has 938 units, and 381LQ561M250J032 has 986 units in stock.
