Parameter Comparison

Engineering Selection Recommendations

LP332M050C3P3 Primary Selection: The LP332M050C3P3 is the baseline reference part with Active product status and full ROHS3 compliance. This part is suitable for applications where the specified 1000-hour lifetime at 105°C meets design requirements.

381LX332M050J022 Substitute: The 381LX332M050J022 is a direct functional equivalent with identical electrical and mechanical core parameters. This substitute offers extended lifetime (3000 hours at 105°C) and higher ripple current ratings (2 A @ 120 Hz and 2.3 A @ 20 kHz) compared to the main part. The height dimension increases to 1.260" (32.00mm), which must be verified against PCB layout constraints. Active product status and ROHS3 compliance are maintained.

SLP332M050C3P3 Substitute: The SLP332M050C3P3 is a direct functional equivalent with identical electrical and mechanical core parameters. This substitute maintains the same height dimension (1.181" / 30.00mm) as the main part and offers extended lifetime (3000 hours at 105°C). ESR is specified at 141 mOhm, representing a minor increase from the main part's 101 mOhm. Active product status and ROHS3 compliance are maintained.

All three parts are manufactured by Cornell Dubilier Electronics (CDE) and are suitable for general-purpose applications within the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the 381LX332M050J022 be used as a direct replacement for the LP332M050C3P3?

A: Yes. The 381LX332M050J022 meets all core electrical and mechanical matching criteria: 3300 µF capacitance, 50 V voltage rating, ±20% tolerance, polar polarization, radial snap-in package, through-hole mounting, 10.00mm lead spacing, and 25.00mm diameter. The height dimension increases from 30.00mm to 32.00mm; verify this dimension against your PCB layout before implementation.

Q: What is the difference between the LP332M050C3P3 and SLP332M050C3P3?

A: Both parts are functionally equivalent with identical capacitance, voltage, tolerance, polarization, package type, and mounting configuration. The primary differences are: (1) SLP332M050C3P3 offers extended lifetime (3000 hours vs. 1000 hours at 105°C), and (2) SLP332M050C3P3 has a specified ESR of 141 mOhm compared to LP332M050C3P3's 101 mOhm. Both maintain identical height dimensions (30.00mm).

Q: Are all three parts RoHS compliant?

A: Yes. The LP332M050C3P3, 381LX332M050J022, and SLP332M050C3P3 are all ROHS3 compliant and REACH unaffected.

Q: Does the increased ESR in the SLP332M050C3P3 affect circuit performance?

A: ESR variation between 101 mOhm and 141 mOhm is within acceptable design tolerances for general-purpose aluminum electrolytic capacitors. Circuit-specific performance impact depends on application requirements; consult your circuit design specifications.

Q: Which substitute part should I select if PCB height is constrained?

A: The SLP332M050C3P3 maintains the same height as the main part (30.00mm). The 381LX332M050J022 has a maximum seated height of 32.00mm and requires verification against available PCB clearance.

Q: Are ripple current ratings critical for substitution?

A: Ripple current ratings are secondary parameters. Both substitute parts offer equal or higher ripple current capacity than the main part, which is acceptable for circuit applications. Verify that your circuit's actual ripple current does not exceed the specified ratings for your selected part.
