Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LP332M050C5P3 is determined by strict equivalence across the following critical parameters:

Core Electrical Parameters:

• Capacitance: 3300 µF (exact match required)
• Voltage Rating: 50 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)

Mechanical Parameters:

• Package Type: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.394" (10.00 mm) (exact match required)
• Diameter: 0.984" (25.00 mm) (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (all substitutes must comply)
• REACH Status: REACH Unaffected (all substitutes must comply)

All identified substitute parts meet these core requirements. Secondary parameters such as ESR, ripple current ratings, and lifetime at temperature are provided for engineering evaluation but do not disqualify substitution eligibility when core parameters align.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain Active product status and full compliance with ROHS3 and REACH regulatory requirements, ensuring suitability for current design implementations and future regulatory environments.

381LX332M050J022 (CDE): This direct manufacturer equivalent from Cornell Dubilier Electronics provides extended operational lifetime (3000 hours at 105°C versus 1000 hours) while maintaining identical electrical and mechanical specifications. The reduced seated height (1.260" versus 1.378") may provide layout advantages in space-constrained applications. This part is suitable for direct substitution where extended reliability is beneficial.

SLP332M050C3P3 (CDE): This Cornell Dubilier Electronics alternative offers the most compact form factor (1.181" seated height) and extended lifetime (3000 hours at 105°C). The ESR specification of 141 mOhm is higher than the main part (101 mOhm), which may affect performance in applications with stringent ripple current or thermal dissipation requirements. This part is suitable for applications where physical space is a primary constraint.

LGU1H332MELA (Nichicon): This Nichicon equivalent provides 3000-hour lifetime at 105°C with identical mechanical dimensions to the 381LX variant (1.260" seated height). Ripple current ratings (2.0 A @ 120 Hz, 2.3 A @ 50 kHz) exceed the main part specifications. This part is suitable for direct substitution with extended operational reliability.

LGY1H332MELA30 (Nichicon): This Nichicon part offers the longest operational lifetime (5000 hours at 105°C) among all identified substitutes. The compact seated height (1.260") and enhanced ripple current handling (1.8 A @ 120 Hz, 2.07 A @ 50 kHz) support demanding applications. This part is suitable for applications requiring maximum operational longevity and thermal stability.

Frequently Asked Questions (FAQ)

Q: Can LP332M050C5P3 be directly replaced with 381LX332M050J022?

A: Yes. Both parts are manufactured by Cornell Dubilier Electronics and share identical capacitance (3300 µF), voltage rating (50 V), tolerance (±20%), package type (Radial, Can - Snap-In), lead spacing (0.394"), and diameter (0.984"). The 381LX variant has a reduced seated height (1.260" versus 1.378") and extended lifetime (3000 hours versus 1000 hours at 105°C). Direct substitution is electrically and mechanically valid.

Q: What is the difference between CDE and Nichicon substitute parts?

A: All substitute parts meet identical core electrical and mechanical specifications. The primary differences are manufacturer origin and secondary performance characteristics. CDE parts (381LX332M050J022 and SLP332M050C3P3) and Nichicon parts (LGU1H332MELA and LGY1H332MELA30) are functionally equivalent. Selection between manufacturers depends on supply chain availability, procurement preferences, and secondary performance requirements such as ESR or ripple current ratings.

Q: Does the reduced height of SLP332M050C3P3 affect compatibility?

A: The SLP332M050C3P3 has a seated height of 1.181" compared to the main part's 1.378". This reduced height is mechanically compatible with through-hole PCB layouts designed for the original part, as the lead spacing (0.394") and diameter (0.984") remain identical. The reduced height may provide layout advantages but does not create compatibility issues.

Q: Which substitute part has the best thermal performance?

A: LGY1H332MELA30 offers the longest operational lifetime at 105°C (5000 hours) among all identified substitutes. This extended lifetime indicates superior thermal stability and reliability in high-temperature environments. For applications requiring maximum thermal performance, LGY1H332MELA30 is the appropriate selection.

Q: Are all substitute parts RoHS3 and REACH compliant?

A: Yes. All identified substitute parts (381LX332M050J022, SLP332M050C3P3, LGU1H332MELA, and LGY1H332MELA30) are ROHS3 Compliant and REACH Unaffected, matching the compliance status of the main part LP332M050C5P3.

Q: Can substitute parts be mixed in the same circuit or assembly?

A: All substitute parts meet identical core electrical specifications (3300 µF, 50 V, ±20% tolerance, polar configuration). They are mechanically and electrically interchangeable within the same circuit or assembly. However, mixing parts with different ESR or ripple current ratings in parallel configurations may result in unequal current distribution. For parallel configurations, parts with similar electrical characteristics should be selected.

Q: What is the significance of ESR differences between parts?

A: ESR (Equivalent Series Resistance) affects heat dissipation and ripple current handling. The main part LP332M050C5P3 specifies 101 mOhm @ 120 Hz. SLP332M050C3P3 specifies 141 mOhm, indicating higher internal resistance and greater heat generation under ripple current stress. For applications with high ripple current or thermal constraints, parts with lower ESR (such as the main part or 381LX variant where ESR is not specified as higher) are preferred.

Q: How do ripple current ratings affect part selection?

A: Ripple current ratings indicate the maximum AC current the capacitor can handle without exceeding temperature limits. The main part specifies 1.71 A @ 120 Hz and 1.881 A @ 100 kHz. Substitute parts generally offer equal or higher ripple current capacity (381LX: 2.0 A @ 120 Hz; LGU1H: 2.0 A @ 120 Hz; LGY1H: 1.8 A @ 120 Hz). For applications with ripple current exceeding the main part's rating, substitutes with higher ripple current specifications should be selected.
