Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment of the following parameters:

Capacitance value: 560 µF (exact match required)
Voltage rating: 200 V (exact match required)
Tolerance: ±20% (exact match required)
Lead spacing: 0.394" (10.00 mm) (exact match required)
Mounting type: Through Hole (exact match required)
Package type: Radial, Can - Snap-In (exact match required)
Operating temperature range: -40°C ~ 105°C (exact match required)
Polarization: Polar (exact match required)

Substitute parts are grouped into two categories:

Direct Equivalents (3000 Hrs @ 105°C): Parts maintaining identical thermal lifetime specifications as the main part. These include Nichicon LGN and LGU series variants with different physical dimensions and ripple current ratings.

Similar Alternatives (2000 Hrs @ 105°C or Different Ripple Ratings): Parts meeting all electrical and mechanical requirements but with reduced thermal lifetime or alternative ripple current performance. These include Nichicon LGG series and Cornell Dubilier Electronics 381LR and 381LX series.

Engineering Selection Recommendations

All listed substitute parts meet the core electrical specifications: 560 µF capacitance, 200 V voltage rating, ±20% tolerance, and through-hole radial snap-in package format with 10.00 mm lead spacing. All parts are ROHS3 compliant and rated for -40°C to 105°C operation.

For applications requiring maximum thermal stability: Select parts with 3000 Hrs @ 105°C lifetime rating. Nichicon LGU, LGN, and LGW series, along with Cornell Dubilier 381LR and 381LX series, meet this requirement. The main part LGU2D561MELY and direct equivalent LGN2D561MELY40 are suitable for this criterion.

For applications with space constraints: Nichicon LGG2D561MELA25 and LGG2D561MELZ30 offer compact form factors with reduced height and diameter, though thermal lifetime is reduced to 2000 Hrs @ 105°C.

For applications requiring higher ripple current handling: Nichicon LGW2D561MELA30 provides 2.3 A @ 120 Hz and 3.45 A @ 50 kHz, exceeding the main part's ripple current specifications. Cornell Dubilier 381LR561M200H042 also provides elevated ripple current at 2.14 A @ 120 Hz.

For cross-manufacturer compatibility: Cornell Dubilier Electronics 381LR561M200H042 and 381LX561M200H042 are functionally equivalent alternatives from a different manufacturer, maintaining identical electrical ratings and thermal specifications.

Frequently Asked Questions (FAQ)

Q: Can LGN2D561MELY40 directly replace LGU2D561MELY on a circuit board?

A: Yes. Both parts share identical electrical specifications (560 µF, 200 V, ±20%, 3000 Hrs @ 105°C) and lead spacing (10.00 mm). The primary difference is physical height: LGN2D561MELY40 is 1.654" (42.00 mm) versus LGU2D561MELY at 1.969" (50.00 mm). Verify available board space before substitution.

Q: What is the difference between Nichicon LGU, LGN, LGW, and LGG series?

A: These series differ in physical dimensions, ripple current ratings, and thermal lifetime. LGU and LGN series maintain 3000 Hrs @ 105°C. LGG series reduces thermal lifetime to 2000 Hrs @ 105°C but offers compact form factors. LGW series provides enhanced ripple current handling (2.3 A @ 120 Hz) while maintaining 3000 Hrs @ 105°C.

Q: Can I use a 2000 Hrs @ 105°C part (LGG series) in place of a 3000 Hrs @ 105°C part (LGU series)?

A: Substitution is electrically valid if all other parameters match. However, thermal lifetime is reduced. Applications requiring extended operational life or elevated ambient temperatures should retain the 3000 Hrs @ 105°C specification.

Q: Are Cornell Dubilier 381LR and 381LX series compatible with Nichicon parts?

A: Yes. Both Cornell Dubilier parts meet identical electrical and mechanical specifications: 560 µF, 200 V, ±20%, 3000 Hrs @ 105°C, 10.00 mm lead spacing, and radial snap-in package. Ripple current ratings differ slightly. Both are ROHS3 compliant.

Q: What does the height difference mean for board layout?

A: Physical height varies from 0.984" (25.00 mm) to 1.969" (50.00 mm) across substitute options. Verify clearance above the capacitor location on the circuit board. Taller parts (LGU2D561MELY, LGU2D561MELZ) require greater vertical space. Shorter alternatives (LGG2D561MELA25, LGU2D561MELB) fit space-constrained designs.

Q: Does ripple current rating affect substitution compatibility?

A: Ripple current rating indicates the capacitor's ability to handle AC current superimposed on DC voltage. Higher ripple current ratings (LGW2D561MELA30 at 2.3 A @ 120 Hz) provide margin for demanding applications. Lower ratings (381LX561M200H042 at 1.5 A @ 120 Hz) are suitable for lower-ripple circuits. Select based on actual circuit requirements.
