Engineering Selection Recommendations

381LX822M050A032 (CDE Direct Equivalent)

This part is a direct electrical equivalent with identical capacitance, tolerance, voltage rating, and lead spacing. The primary advantage is extended operational lifetime of 3000 Hrs @ 105°C compared to 1000 Hrs for the main part. Physical height is reduced from 50.00 mm to 37.00 mm, which may provide PCB layout benefits in space-constrained applications. All compliance certifications (RoHS3, REACH unaffected) are maintained. This substitute is suitable for direct replacement when extended service life is required.

SLP822M080H9P3 (CDE Upgraded Variant)

This part provides an upgraded voltage rating of 80 V while maintaining the same 8200 µF capacitance and ±20% tolerance. The 80 V rating provides additional circuit margin for applications subject to voltage transients or overvoltage conditions. Operational lifetime is extended to 3000 Hrs @ 105°C. Physical dimensions match the main part (50.00 mm height, 35.00 mm diameter), ensuring identical PCB footprint compatibility. Ripple current ratings are higher (4.2 A @ 120 Hz, 5.25 A @ 20 kHz), supporting higher current applications. RoHS3 compliance is maintained. This substitute is appropriate when circuit redesign permits higher voltage operation or when enhanced transient protection is required.

381LX822M050K452 (CDE Similar Alternative)

This part maintains identical electrical specifications (8200 µF, 50 V, ±20% tolerance) and lead spacing (10.00 mm) but differs in physical dimensions. The diameter is reduced to 30.00 mm and height to 47.00 mm. Operational lifetime is extended to 3000 Hrs @ 105°C. This substitute is suitable only when the reduced physical dimensions are compatible with PCB layout constraints and when the smaller can diameter does not conflict with mechanical clearance requirements. RoHS3 compliance is maintained.

LGU1H822MELC (Nichicon Direct Equivalent)

This part is manufactured by Nichicon and provides identical electrical specifications (8200 µF, 50 V, ±20% tolerance) with extended lifetime of 3000 Hrs @ 105°C. Physical dimensions match the main part (35.00 mm diameter, 37.00 mm height). Lead spacing is identical at 10.00 mm. Ripple current ratings are comparable (3.66 A @ 120 Hz). RoHS3 compliance is maintained. This substitute is appropriate when multi-source component strategy is required or when Nichicon supply chain is preferred. Moisture Sensitivity Level is listed as Not Applicable, indicating different handling requirements compared to the main part.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher voltage rating than the original LP822M050H9P3?

A: Yes. The SLP822M080H9P3 with 80 V rating is a valid substitute for the 50 V main part. Higher voltage ratings provide additional circuit margin and are electrically compatible in applications designed for 50 V operation. The circuit will function correctly with the higher-rated component.

Q: What is the difference between the 381LX822M050A032 and the main part LP822M050H9P3?

A: Both parts have identical capacitance (8200 µF), tolerance (±20%), voltage rating (50 V), and lead spacing (10.00 mm). The primary differences are: operational lifetime extended from 1000 Hrs to 3000 Hrs @ 105°C, and physical height reduced from 50.00 mm to 37.00 mm. The reduced height may provide PCB layout advantages.

Q: Is the 381LX822M050K452 a direct replacement for the LP822M050H9P3?

A: The 381LX822M050K452 is electrically equivalent but has different physical dimensions. The can diameter is reduced from 35.00 mm to 30.00 mm, and height is reduced from 50.00 mm to 47.00 mm. This substitute is suitable only if the smaller physical dimensions are compatible with your PCB layout and mechanical clearance requirements. Lead spacing remains identical at 10.00 mm.

Q: Can I substitute the Nichicon LGU1H822MELC for the CDE LP822M050H9P3?

A: Yes. The LGU1H822MELC provides identical electrical specifications (8200 µF, 50 V, ±20% tolerance) with extended lifetime of 3000 Hrs @ 105°C. Physical dimensions are compatible (35.00 mm diameter, 37.00 mm height, 10.00 mm lead spacing). This substitute is appropriate for multi-source strategies or when Nichicon supply is preferred. Note that Moisture Sensitivity Level differs (Not Applicable vs. Level 1).

Q: What parameters must match exactly when selecting a substitute?

A: The following parameters must match exactly: capacitance (8200 µF), tolerance (±20%), lead spacing (10.00 mm), package type (Radial, Can - Snap-In), mounting type (Through Hole), and polarization (Polar). Voltage rating may be equal or higher. Lifetime and physical dimensions may vary if compatible with application requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (381LX822M050A032, SLP822M080H9P3, 381LX822M050K452, and LGU1H822MELC) are RoHS3 compliant and maintain REACH unaffected status, matching the regulatory compliance of the main part LP822M050H9P3.

Q: What is the advantage of the extended 3000 Hrs lifetime in substitute parts?

A: Extended lifetime of 3000 Hrs @ 105°C compared to 1000 Hrs provides longer operational service life in high-temperature environments. This is beneficial for applications with continuous operation at elevated temperatures or for equipment requiring extended mean time between failures (MTBF).

Q: Can I use the SLP822M080H9P3 in a circuit designed for 50 V operation?

A: Yes. The SLP822M080H9P3 with 80 V rating is fully compatible in circuits designed for 50 V operation. The higher voltage rating provides additional safety margin against voltage transients and overvoltage conditions without affecting normal circuit operation.
