Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SLP151M400C3P3 are identified based on the following critical parameters that determine functional compatibility:

Primary Matching Criteria:

• Capacitance: 150 µF (exact match required)
• Tolerance: ±20% (exact match required)
• 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)
• Physical Dimensions: 0.984" Dia × 1.181" Height (exact match required)
• Operating Temperature Range: -25°C ~ 105°C (exact match required)
• Lifetime @ 105°C: 3000 Hrs (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

Secondary Compatibility Parameters:

• Voltage Rating: 400 V or higher (equal or upgraded voltage acceptable)
• ESR: Lower or equal values preferred for performance optimization

The SLP151M450C3P3 qualifies as an upgrade substitute with identical capacitance, tolerance, package, dimensions, and thermal performance, but with an elevated voltage rating of 450 V and improved ESR characteristics. The LGU2G151MELA from Nichicon qualifies as a parametric equivalent with matching capacitance, voltage, tolerance, package, dimensions, and thermal performance from an alternative manufacturer.

Parameter Comparison

Engineering Selection Recommendations

SLP151M450C3P3 (Upgrade Substitute): The SLP151M450C3P3 is an upgrade substitute within the same manufacturer series (SLP0712TE). It maintains all electrical and mechanical specifications of the main part while providing a higher voltage rating of 450 V instead of 400 V. The improved ESR of 2.121 Ohm compared to 2.212 Ohm offers enhanced performance characteristics. Both parts are Active status, ROHS3 compliant, and share identical thermal performance. This substitute is suitable for applications where higher voltage margin or improved ESR performance is beneficial.

LGU2G151MELA (Parametric Equivalent): The LGU2G151MELA from Nichicon is a parametric equivalent offering identical capacitance, voltage rating, tolerance, package type, mechanical dimensions, and thermal performance. As an alternative manufacturer source, this part provides supply chain flexibility while maintaining full electrical and mechanical compatibility. Both parts are Active status and ROHS3 compliant. The LGU2G151MELA provides additional ripple current specifications (880 mA @ 120 Hz and 1.2584 A @ 50 kHz) not specified for the main part.

All substitute parts maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory conformance for new designs and production.

Frequently Asked Questions (FAQ)

Q: Can the SLP151M450C3P3 be used as a direct replacement for the SLP151M400C3P3?

A: Yes. The SLP151M450C3P3 is a direct mechanical and electrical substitute with identical capacitance (150 µF), tolerance (±20%), package type (Radial, Can - Snap-In), lead spacing (10.00 mm), physical dimensions (0.984" Dia × 1.181" Height), and thermal performance (3000 Hrs @ 105°C). The higher voltage rating (450 V vs. 400 V) and improved ESR (2.121 Ohm vs. 2.212 Ohm) make it a compatible upgrade.

Q: Is the LGU2G151MELA from Nichicon compatible with the SLP151M400C3P3?

A: Yes. The LGU2G151MELA matches all critical parameters: 150 µF capacitance, ±20% tolerance, 400 V voltage rating, Radial Can - Snap-In package, 10.00 mm lead spacing, 0.984" Dia × 1.181" Height dimensions, and 3000-hour lifetime at 105°C. It is suitable for applications requiring an alternative manufacturer source.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by exact matching of: capacitance (150 µF), tolerance (±20%), voltage rating (400 V or higher), package type (Radial, Can - Snap-In), lead spacing (10.00 mm), physical dimensions (0.984" Dia × 1.181" Height), mounting type (Through Hole), operating temperature range (-25°C ~ 105°C), and thermal performance (3000 Hrs @ 105°C). All substitute parts must be ROHS3 compliant.

Q: Can these parts be used in new designs?

A: Yes. All parts listed—SLP151M400C3P3, SLP151M450C3P3, and LGU2G151MELA—are Active status products, indicating current availability and suitability for new design implementations. All are ROHS3 compliant for regulatory conformance.

Q: What is the difference between the main part and the upgrade substitute?

A: The primary differences are voltage rating (400 V vs. 450 V) and ESR (2.212 Ohm vs. 2.121 Ohm). The upgrade substitute provides higher voltage margin and lower equivalent series resistance, which can improve performance in applications sensitive to ESR characteristics. All other electrical and mechanical specifications are identical.

Q: Are there inventory considerations for these substitutes?

A: Current inventory levels are: SLP151M400C3P3 (1107 Pcs), SLP151M450C3P3 (3256 Pcs), and LGU2G151MELA (3614 Pcs). Inventory status should be verified at time of procurement as levels change with production and sales activity.
