Engineering Selection Recommendations

381LX332M063A012 - Direct Manufacturer Equivalent

This part is the primary substitute for the LP332M063H3P3. All critical electrical and mechanical parameters are identical. The 381LX series offers extended lifetime (3000 Hrs @ 105°C versus 1000 Hrs), providing improved reliability in continuous-duty applications. The seated height is 3 mm shorter (27.00 mm vs. 30.00 mm), which may provide space advantages in compact assemblies. Both parts are Active status and ROHS3 compliant. This substitute is suitable for direct replacement in all applications where the LP332M063H3P3 is specified.

SLP332M063E3P3 - Similar Manufacturer Alternative

This part meets all critical electrical parameters and mounting requirements. The can diameter is reduced to 30.00 mm (versus 35.00 mm), which may affect mechanical fit in applications with tight radial space constraints. The seated height matches the original part (30.00 mm). ESR is higher at 121 mOhm compared to 76 mOhm, which may impact ripple current handling in high-frequency applications. Lifetime is extended to 3000 Hrs @ 105°C. This substitute is suitable for applications where the smaller can diameter is compatible with PCB layout and where the higher ESR does not exceed circuit requirements. Both parts are Active status and ROHS3 compliant.

Compliance and Regulatory Status

All three parts (LP332M063H3P3, 381LX332M063A012, and SLP332M063E3P3) are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Substitution does not introduce regulatory compliance risk.

Frequently Asked Questions (FAQ)

Q: Can the 381LX332M063A012 be used as a direct drop-in replacement for the LP332M063H3P3?

A: Yes. The 381LX332M063A012 is electrically and mechanically identical to the LP332M063H3P3. All critical parameters—capacitance, voltage rating, tolerance, operating temperature, lead spacing, and package type—match exactly. The 3 mm reduction in seated height (27.00 mm vs. 30.00 mm) is a dimensional improvement that does not prevent installation in existing PCB designs. The extended lifetime (3000 Hrs @ 105°C) provides enhanced reliability.

Q: What is the key difference between the 381LX332M063A012 and SLP332M063E3P3?

A: Both parts share identical electrical specifications (3300 µF, 63 V, ±20% tolerance) and operating temperature range. The primary differences are: (1) Can diameter: 381LX is 35.00 mm (matching the original LP332M063H3P3), while SLP332M063E3P3 is 30.00 mm; (2) ESR: 381LX does not specify ESR, while SLP332M063E3P3 is 121 mOhm (higher than the original 76 mOhm); (3) Seated height: 381LX is 27.00 mm, SLP332M063E3P3 is 30.00 mm. The 381LX332M063A012 is the closer mechanical equivalent.

Q: Will the SLP332M063E3P3 fit in the same PCB footprint as the LP332M063H3P3?

A: The lead spacing (10.00 mm) is identical, so the part will mount to the same PCB holes. However, the can diameter is reduced from 35.00 mm to 30.00 mm. If the PCB layout includes mechanical clearance constraints or mounting clips designed for the 35.00 mm diameter, the SLP332M063E3P3 may not fit securely. Verify mechanical compatibility before substitution.

Q: Does the higher ESR of the SLP332M063E3P3 (121 mOhm vs. 76 mOhm) affect circuit performance?

A: ESR affects ripple current handling and heat dissipation. The SLP332M063E3P3 has 59% higher ESR than the LP332M063H3P3. In applications with high ripple current or strict thermal constraints, this difference may be significant. Verify that the circuit design tolerates the higher ESR before substitution. The 381LX332M063A012 does not specify ESR but is electrically equivalent to the original part.

Q: Are all three parts RoHS compliant?

A: Yes. The LP332M063H3P3, 381LX332M063A012, and SLP332M063E3P3 are all ROHS3 compliant. Substitution does not introduce RoHS compliance risk.

Q: What is the inventory status of these parts?

A: LP332M063H3P3: 937 Pcs in stock. 381LX332M063A012: 2162 Pcs in stock. SLP332M063E3P3: 759 Pcs in stock. All parts are available as new original stock.

Q: Can I use the 381LX332M063A012 in applications where the LP332M063H3P3 is specified?

A: Yes. The 381LX332M063A012 is a direct equivalent with superior lifetime rating (3000 Hrs @ 105°C vs. 1000 Hrs). It is suitable for all applications where the LP332M063H3P3 is specified. The extended lifetime may provide additional design margin in reliability-critical applications.
