Key Parameters

Substitute Part Grouping Explanation

Substitution of SLPX331M450H5P3 is determined by three critical electrical parameters: capacitance (330 µF), rated voltage (450 V), and tolerance (±20%). All substitute parts meet these electrical specifications. Secondary selection criteria include ESR, lifetime rating, ripple current capability, and physical dimensions (lead spacing, diameter, and height).

Substitution logic is organized by two primary factors:

1. Thermal Performance: Parts are available with 2000 hours or 3000 hours lifetime rating at 85°C, allowing selection based on reliability requirements.
2. Physical Form Factor: Substitute parts vary in diameter (25.40 mm to 35.00 mm) and height (32.00 mm to 52.00 mm), enabling installation into space-constrained or standard mounting configurations.

All substitute parts maintain identical lead spacing (0.394" / 10.00 mm), through-hole mounting type, and radial snap-in package configuration. All are rated for -25°C to 85°C operating temperature and maintain compliance with ROHS3 or RoHS standards.

Parameter Comparison

Engineering Selection Recommendations

CDE Alternatives: SLPX331M450E7P3 is an identical electrical equivalent (330 µF, 450 V, 804 mOhm ESR, 3000 Hrs @ 85°C) from the same manufacturer series (SLPX) with higher inventory availability (2562 units). This part differs only in physical dimensions—reduced diameter (30.00 mm vs. 35.00 mm) and increased height (40.00 mm vs. 35.00 mm)—suitable for vertical mounting constraints.

High ESR Alternative: 380LQ331M450A022 offers the lowest ESR (600 mOhm) among CDE options, with shorter mounted height (32.00 mm), but rated for 2000 hours at 85°C rather than 3000 hours. This part is suitable for applications with reduced thermal stress or shorter duty cycles.

Compact Form Factor: 380LX331M450K052 maintains 3000-hour thermal rating and provides the lowest ESR (550 mOhm) with the smallest diameter (30.00 mm) and tallest profile (52.00 mm). This configuration addresses both electrical and spatial requirements for compact assemblies.

Cross-Manufacturer Options: Chemi-Con ESMQ451VSN331MR40S and ESMQ451VSN331MQ50S provide RoHS-compliant alternatives with 2000-hour ratings. Both share identical electrical ratings (330 µF, 450 V) and lead spacing (10.00 mm) as the main part but differ in diameter and height. These options are suitable for applications where manufacturer diversity is required.

Frequently Asked Questions (FAQ)

Q: Can I substitute SLPX331M450H5P3 with a different diameter part? A: Yes. All substitute parts maintain the same lead spacing (0.394" / 10.00 mm) and through-hole mounting type. Physical diameter varies from 25.40 mm to 35.00 mm, and height from 32.00 mm to 52.00 mm. Verify available PCB space before substitution.

Q: What is the difference between 2000-hour and 3000-hour rated parts? A: Lifetime rating specifies operating hours at 85°C. The main part (SLPX331M450H5P3) and several substitutes (380LX331M450A042, 380LX331M450K052, SLPX331M450E7P3) are rated for 3000 hours. Chemi-Con alternatives (ESMQ451VSN331MR40S, ESMQ451VSN331MQ50S) and 380LQ331M450A022 are rated for 2000 hours. Select based on required operating duration and thermal environment.

Q: Is ESR (Equivalent Series Resistance) a substitution criterion? A: ESR is a secondary consideration for substitution. The main part has 804 mOhm ESR. Substitutes range from 550 mOhm to 603 mOhm (CDE) with Chemi-Con parts providing no specified ESR value. Lower ESR reduces heat generation and improves ripple current performance in high-frequency applications.

Q: Can I use a Chemi-Con capacitor to replace a Cornell Dubilier capacitor? A: Yes. Chemi-Con ESMQ451VSN331MR40S and ESMQ451VSN331MQ50S meet the core electrical specifications (330 µF, 450 V, ±20% tolerance) and maintain compatibility with PCB mounting (10.00 mm lead spacing, through-hole). Both are RoHS compliant. Verify PCB space requirements due to different physical dimensions.

Q: What is the significance of lead spacing in substitution? A: All substitute parts maintain identical lead spacing (0.394" / 10.00 mm). This parameter determines PCB pad pattern compatibility. No lead spacing adaptation is required for any listed substitute.

Q: Which substitute offers the best thermal performance? A: 380LX331M450K052 offers the lowest ESR (550 mOhm) with a 3000-hour thermal rating, resulting in the lowest heat dissipation for given ripple current. SLPX331M450E7P3 provides identical 3000-hour rating with the same ESR as the main part and higher inventory availability.

Q: Are all substitutes ROHS3 or RoHS compliant? A: Yes. All CDE parts are ROHS3 compliant. Chemi-Con parts (ESMQ451VSN331MR40S, ESMQ451VSN331MQ50S) are RoHS compliant. Both standards are acceptable for modern applications.
