Frequently Asked Questions (FAQ)

Q: Can LGN2V561MELC35 or LQS2V561MELC35 be used as direct replacements for SLPX561M350H5P3?

A: Yes. Both Nichicon parts are direct mechanical and electrical substitutes. They maintain identical capacitance (560 µF), voltage rating (350 V), tolerance (±20%), lead spacing (10.00 mm), physical dimensions (35.00 mm diameter, 37.00 mm height), and snap-in package configuration. The primary difference is extended operating temperature capability to 105°C, which represents an upgrade in thermal performance.

Q: What is the difference between LGN2V561MELC35 and LQS2V561MELC35?

A: Both parts are manufactured by Nichicon and share identical electrical specifications, voltage ratings, capacitance values, and physical dimensions. The difference lies in their internal series designation (LGN versus LQS). Both are functionally equivalent for the SLPX561M350H5P3 application. Selection between them is based on availability and procurement lead times.

Q: Is LLS2V561MELC suitable for applications currently using SLPX561M350H5P3?

Q: What is the significance of the extended temperature rating in LGN2V561MELC35 and LQS2V561MELC35?

A: The extended operating temperature range to 105°C provides additional thermal margin in applications subject to elevated ambient conditions or internal heat generation. The 3000-hour lifetime specification is maintained at the higher temperature rating, indicating equivalent reliability performance under more demanding thermal conditions.

Q: How do ripple current ratings compare between the main part and substitutes?

A: The SLPX561M350H5P3 specifies 2.75 A @ 120 Hz and 4.04 A @ 20 kHz. The upgrade parts (LGN2V561MELC35, LQS2V561MELC35) specify 1.5 A @ 120 Hz and 2.145 A @ 50 kHz. The parametric equivalent LLS2V561MELC specifies 2.75 A @ 120 Hz and 3.9325 A @ 50 kHz. Ripple current ratings vary by manufacturer design but remain within acceptable operational limits for general-purpose applications. Application-specific ripple current requirements should be verified against the selected part's rating.

Q: What is the inventory status for each part?

A: SLPX561M350H5P3 (CDE): 849 pieces. LGN2V561MELC35 (Nichicon): 273,882 pieces. LQS2V561MELC35 (Nichicon): 273,982 pieces. LLS2V561MELC (Nichicon): 956 pieces. The Nichicon upgrade parts offer significantly higher inventory availability for extended procurement windows.
