Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are qualified for direct replacement of the 229LMB025M2EE based on the following criteria:

Electrical Compatibility: All three parts share identical capacitance (22000 µF), voltage rating (25 V), tolerance (±20%), and thermal lifetime (3000 Hrs @ 105°C). Operating temperature ranges are identical across all variants.

Mechanical Compatibility: Lead spacing, case diameter, and mounting type are identical. The SLP223M025H5P3 has a slightly reduced seated height (1.378" vs. 1.457"), which may provide a marginal advantage in space-constrained applications. The 381LX223M025A032 maintains the same seated height as the primary part.

Regulatory Compliance: All three parts are ROHS3 compliant, REACH unaffected, and carry MSL rating of 1 (unlimited moisture sensitivity). No compliance barriers exist for substitution.

Performance Characteristics: The SLP223M025H5P3 exhibits lower ESR (27 mOhm vs. 33.9109 mOhm) and higher ripple current ratings, making it suitable for applications requiring enhanced thermal performance. The 381LX223M025A032 provides comparable ripple current performance to the primary part.

Availability: The SLP223M025H5P3 offers the highest inventory availability (2852 units), followed by the 229LMB025M2EE (1149 units) and 381LX223M025A032 (1004 units).

Frequently Asked Questions (FAQ)

Q: Can SLP223M025H5P3 be used as a direct replacement for 229LMB025M2EE?

A: Yes. Both parts are 22000 µF, 25 V aluminum electrolytic capacitors with identical tolerance, lifetime rating, operating temperature range, and package configuration. The lead spacing and case diameter are identical, enabling direct board-level substitution without design modification.

Q: What is the difference in height between the substitute parts?

A: The SLP223M025H5P3 has a seated height of 1.378" (35.00mm), while both the 229LMB025M2EE and 381LX223M025A032 have a seated height of 1.457" (37.00mm). This 0.079" (2.00mm) difference may be relevant in applications with vertical space constraints.

Q: Are there ESR differences between the parts?

A: The 229LMB025M2EE has an ESR of 33.9109 mOhm @ 120Hz. The SLP223M025H5P3 has a lower ESR of 27 mOhm @ 120Hz. The 381LX223M025A032 does not specify ESR. Lower ESR generally results in reduced heat generation and improved ripple current handling.

Q: Do all parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited). No compliance barriers exist for substitution in regulated applications.

Q: What are the ripple current differences?

A: At 120 Hz, the 229LMB025M2EE supports 3.95 A, while both SLP223M025H5P3 and 381LX223M025A032 support 4.3 A. At high frequency (10-20 kHz), the SLP223M025H5P3 supports 5.38 A @ 20 kHz, the 381LX223M025A032 supports 4.9 A @ 20 kHz, and the 229LMB025M2EE supports 4.938 A @ 10 kHz. Applications requiring maximum ripple current handling should prioritize the SLP223M025H5P3.

Q: Can these parts be used interchangeably in production?

A: Yes, provided that the specific height and ESR characteristics do not conflict with circuit design requirements. All parts share identical electrical ratings, thermal lifetime, and compliance certifications. Board layout verification is recommended when substituting the SLP223M025H5P3 due to its reduced height.

Q: What is the lead spacing for all parts?

A: All three parts have identical lead spacing of 0.394" (10.00mm), ensuring compatibility with existing PCB footprints designed for the 229LMB025M2EE.
