Engineering Selection Recommendations

For Direct Pin-Compatible Replacement (Same Footprint and Voltage):

B41231A3229M000 and B41252A3229M provide direct electrical equivalence at 10 V rating with identical physical dimensions and lead spacing. Both parts are manufactured by EPCOS - TDK Electronics and maintain active product status with ROHS3 compliance. B41231A3229M000 matches the original ripple current specification of 4.79 A at 120 Hz and operates within the -40°C to 85°C temperature range. B41252A3229M extends operating temperature to 105°C with reduced ripple current capability (3.35 A at 120 Hz).

For Upgraded Voltage Margin (Same Footprint, Higher Voltage):

The 16 V rated parts (380LQ223M016H042, 380LX223M016H042, 381LQ223M016H042, 381LX223M016H042) maintain identical physical dimensions and lead spacing while providing higher voltage headroom. These parts are manufactured by Cornell Dubilier Electronics and carry active product status with ROHS3 compliance. The 381-series variants offer extended operating temperature to 105°C and improved ESR characteristics (34 mOhm versus 38 mOhm). The 380LX223M016H042 provides extended lifetime (3000 hours at 85°C) while maintaining the original temperature range.

For Enhanced Thermal Performance (Different Footprint):

SLP223M025H5P3 offers 25 V rating with superior ESR (27 mOhm) and extended lifetime (3000 hours at 105°C). This part requires PCB layout modification due to larger physical dimensions (1.378" diameter and height versus 0.866" and 1.654" respectively). This option is suitable only when board space permits the larger package footprint.

Frequently Asked Questions (FAQ)

Q: Can I use a 16 V rated substitute in place of the 10 V original part?

A: Yes. The 16 V rated parts (380LQ223M016H042, 380LX223M016H042, 381LQ223M016H042, 381LX223M016H042) are electrically compatible. Higher voltage ratings provide additional safety margin in the circuit. All maintain identical capacitance (22000 µF), tolerance (±20%), package type (Radial, Can - Snap-In), and physical dimensions (0.866" diameter, 1.654" height, 0.394" lead spacing).

Q: What is the difference between the 380-series and 381-series 16 V substitutes?

A: The 381-series parts feature lower ESR (34 mOhm versus 38 mOhm) and extended operating temperature range (-40°C to 105°C versus -40°C to 85°C). The 381LX223M016H042 additionally provides 3000-hour lifetime at 105°C compared to 2000 hours for the 381LQ223M016H042. The 380-series maintains the original -40°C to 85°C temperature range.

Q: Can I use SLP223M025H5P3 as a direct replacement?

A: SLP223M025H5P3 is electrically compatible but requires PCB layout modification. This part has larger physical dimensions (1.378" diameter and height) compared to the original 0.866" diameter and 1.654" height. Use this option only when board space permits the larger package footprint.

Q: Which substitute offers the best thermal performance?

A: SLP223M025H5P3 provides the best thermal performance with 3000-hour lifetime at 105°C and lowest ESR (27 mOhm at 120 Hz). Among same-footprint options, the 381LX223M016H042 offers 3000-hour lifetime at 105°C with 34 mOhm ESR.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the original MALIEYN07LB522C02K specification.

Q: What is the ripple current capability of each substitute?

A: The original part and B41231A3229M000 both support 4.79 A at 120 Hz. The 380-series parts support 4.52 A at 120 Hz. The 381-series parts support 3.8 A at 120 Hz. B41252A3229M supports 3.35 A at 120 Hz. SLP223M025H5P3 supports 4.3 A at 120 Hz. Select based on circuit ripple current requirements.

Q: Can I use parts with different ESR values?

A: ESR differences affect circuit performance in applications sensitive to impedance characteristics. The original part specifies 30 mOhm at 120 Hz. Substitutes range from 27 mOhm (SLP223M025H5P3) to 38 mOhm (380-series). Verify circuit tolerance to ESR variation before selection.
