Engineering Selection Recommendations

381LX223M035A052 (Upgrade - Higher Voltage Rating): All CDE components listed are active, RoHS3 compliant, and REACH unaffected, making them suitable for regulatory requirement adherence. The 381LX223M035A052 provides a voltage upgrade from 25 V to 35 V with tripled lifetime (3000 hours at 105°C versus 1000 hours), making it the recommended upgrade for designs requiring enhanced reliability and voltage margin. Height increase of 2.047" (52.00 mm) requires PCB layout verification.

SLP223M035H9P3 (Upgrade - Higher Voltage Rating, Optimized Height): This part maintains the 1.969" (50.00 mm) height of the original LP223M025H9P3 while providing 35 V rating and 3000-hour lifetime. The ESR of 24 mOhm is comparable to the 23 mOhm original specification, making it an optimal direct substitution for voltage-constrained applications. Active product status with full RoHS3 compliance.

381LX223M025A032 and 381LX223M025K452 (Similar - Same Voltage, Extended Lifetime): These parts maintain the 25 V rating and ±20% tolerance while extending lifetime to 3000 hours. The 381LX series parts feature different form factors (diameter and height variations). 381LX223M025K452 has reduced diameter (1.181" / 30.00 mm) and may provide space optimization. Selection between these parts depends on available PCB space and mechanical constraints.

SLP223M025H5P3 (Similar - Same Voltage, Compact Height): This part offers the lowest seated height at 1.378" (35.00 mm), providing significant vertical space savings while maintaining 25 V rating, 22000 µF capacitance, and 3000-hour lifetime. ESR of 27 mOhm is slightly elevated compared to the original 23 mOhm. Selection is appropriate for height-constrained PCB designs.

Frequently Asked Questions (FAQ)

Q: Can I directly substitute the LP223M025H9P3 with a 35 V rated part? A: Yes. The 381LX223M035A052 and SLP223M035H9P3 are direct electrical substitutes with superior voltage ratings. A higher voltage rating maintains full backward compatibility. Verify PCB mechanical clearance for the 381LX223M035A052, which has increased height of 2.047" (52.00 mm).

Q: What is the difference between the upgrade parts (35 V) and similar parts (25 V)? A: Upgrade parts provide higher voltage rating (35 V versus 25 V) and extended lifetime (3000 hours versus 1000 hours at 105°C), making them suitable for reliability-critical applications. Similar parts maintain the original 25 V rating and offer alternative physical dimensions or improved ESR characteristics while extending lifetime to 3000 hours.

Q: Are there mechanical fit constraints when substituting? A: Yes. Lead spacing (0.394" / 10.00 mm) and mounting type (Through Hole, Radial, Can - Snap-In) are identical across all substitutes. However, can diameter and seated height vary. The 381LX223M025K452 has reduced diameter (1.181" / 30.00 mm), and the SLP223M025H5P3 has reduced height (1.378" / 35.00 mm). Verify PCB layout constraints before selection.

Q: Which substitute provides the best ESR performance? A: The original LP223M025H9P3 (23 mOhm at 120 Hz) and SLP223M035H9P3 (24 mOhm at 120 Hz) provide the lowest ESR values. The SLP223M025H5P3 has 27 mOhm ESR. The 381LX series parts do not specify ESR in the provided data.

Q: Is ripple current capacity a constraint in substitution? A: Ripple current must meet or exceed circuit requirements. The LP223M025H9P3 is rated at 4.857 A @ 120 Hz. The 381LX223M035A052 (5.0 A @ 120 Hz) and SLP223M025H5P3 (4.3 A @ 120 Hz) are suitable if the circuit ripple current requirement falls within their respective ratings.

Q: Are all these parts RoHS3 compliant? A: Yes. All listed substitutes are RoHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), meeting current regulatory standards for electronic component procurement.

Q: What is the lifetime difference between the main part and substitutes? A: The LP223M025H9P3 is rated for 1000 hours at 105°C. All five substitute parts are rated for 3000 hours at 105°C, providing a three-fold improvement in expected operational lifetime at elevated temperature.
