Engineering Selection Recommendations

All substitute parts maintain full Active product status and RoHS3 compliance. The 381LX182M063H022 and 381LX182M063J012 offer extended thermal lifetime (3000 Hrs @ 105°C) compared to the original specification (1000 Hrs @ 105°C), suitable for applications requiring enhanced reliability. The LP182M063E1P3 provides equivalent thermal lifetime with minimal ESR variation (140 mOhm vs. 138 mOhm). The SLP182M063C1P3 extends thermal lifetime to 3000 Hrs @ 105°C but exhibits higher ESR (221 mOhm @ 120Hz).

Selection should prioritize space availability constraints, as physical dimensions vary significantly across the substitute options. The 381LX182M063H022 maintains the original diameter (0.866" / 22.00 mm) while reducing seated height to 1.260" (32.00 mm). The 381LX182M063J012, LP182M063E1P3, and SLP182M063C1P3 provide additional space savings with more compact profiles.

Frequently Asked Questions (FAQ)

Q: Can I substitute the LP182M063A7P3 with any of the listed alternatives? A: Yes. All substitute parts are electrically equivalent within the defined 1800 µF, 63 V, ±20% tolerance specification and share identical lead spacing and snap-in mounting configuration. PCB layout compatibility is preserved for all substitutes.

Q: What is the primary difference between the main part and the substitute options? A: The main differences are physical dimensions (diameter and height), thermal lifetime rating (1000 Hrs vs. 3000 Hrs @ 105°C), and ESR characteristics. These variations do not affect electrical compatibility but may influence board layout and thermal performance considerations.

Q: Which substitute part offers the smallest footprint? A: The LP182M063E1P3 and SLP182M063C1P3 both offer the most compact seated height of 0.984" (25.00 mm). The LP182M063E1P3 has a larger diameter (1.181" / 30.00 mm), while the SLP182M063C1P3 uses a 0.984" (25.00 mm) diameter.

Q: Are extended lifetime parts (3000 Hrs @ 105°C) direct replacements? A: Yes. The 381LX182M063H022, 381LX182M063J012, and SLP182M063C1P3 are direct electrical and mechanical replacements with extended thermal lifetime. They do not require circuit modifications and maintain identical electrical performance within the specified tolerance band.

Q: What mounting compatibility considerations apply to these parts? A: All parts use through-hole radial snap-in package configuration with identical 0.394" (10.00 mm) lead spacing. PCB hole pattern and snap-in fixture dimensions remain consistent across all variants.

Q: How does ESR variation affect component selection? A: ESR values provided (138–221 mOhm @ 120Hz) are within acceptable operating ranges for general purpose aluminum electrolytic capacitors. Selection should consider the application's ripple current environment and thermal dissipation requirements. Higher ESR correlates with increased heat generation under high-frequency ripple current conditions.
