476SVL025MEL Equivalent & Substitute Parts Reference

Part Overview

The 476SVL025MEL is a 47 µF, 25 V aluminum electrolytic capacitor in surface mount radial can package, manufactured by Cornell Dubilier / Illinois Capacitor. This component is classified as Active product status and is designed for general purpose applications requiring energy storage, filtering, and signal coupling in low-voltage circuits. The part is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when design requirements permit operation at higher voltage ratings or when improved electrical performance characteristics are needed while maintaining the same capacitance value, tolerance, and physical form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 476SVL025MEL is permitted with the ATB476M035 based on the following criteria:

Matching Parameters (Required for Substitution):

• Capacitance: 47 µF (identical)
• Tolerance: ±20% (identical)
• Polarization: Polar (identical)
• Operating Temperature Range: -55°C to 105°C (identical)
• Lifetime @ 105°C: 3000 Hrs (identical)
• Package Type: Radial, Can - SMD (identical)
• Mounting Type: Surface Mount (identical)
• RoHS Status: ROHS3 Compliant (identical)
• MSL Rating: 1 - Unlimited (identical)

Differing Parameters (Upgrade Characteristics):

• Voltage Rating: 25 V (main part) vs. 35 V (substitute) — higher voltage rating provides additional design margin
• ESR @ 120Hz: 5.64 Ohm (main part) vs. 3.95 Ohm (substitute) — lower ESR improves ripple current handling
• Ripple Current @ 120 Hz: 65 mA (main part) vs. 196 mA (substitute) — higher ripple current capacity
• Ripple Current @ 100 kHz: 97.5 mA (main part) vs. 280 mA (substitute) — higher high-frequency ripple current capacity
• Physical Dimensions: Minor height and land size variations within SMD package specifications

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution Conditions:

The ATB476M035 is a direct substitute for the 476SVL025MEL when the following conditions are met:

1. Voltage Margin Requirement: The circuit design permits operation with a 35 V rated capacitor in place of a 25 V rated capacitor. This substitution provides additional voltage safety margin and is suitable for applications where the supply voltage does not exceed 25 V.

2. Physical Space Availability: The PCB layout accommodates the slightly larger land size (0.287" L x 0.268" W vs. 0.260" L x 0.260" W) and increased height (0.315" vs. 0.307" maximum seated height). These dimensional differences are minor but must be verified against PCB design constraints and component clearance requirements.

3. Compliance Requirements: Both parts maintain identical ROHS3 compliance, MSL 1 rating, and REACH unaffected status, ensuring regulatory equivalence.

4. Performance Enhancement: The substitute part offers improved electrical performance with lower ESR (3.95 Ohm vs. 5.64 Ohm @ 120Hz) and significantly higher ripple current capacity (196 mA vs. 65 mA @ 120 Hz; 280 mA vs. 97.5 mA @ 100 kHz), making it suitable for applications requiring enhanced filtering or higher current ripple handling.

Reverse Substitution Not Recommended:

The 476SVL025MEL cannot substitute for the ATB476M035 in applications designed for the 35 V rated part, as the lower voltage rating creates insufficient safety margin.

Frequently Asked Questions (FAQ)

Q1: Can the ATB476M035 be used as a direct replacement for the 476SVL025MEL on the same PCB?

A: Yes, provided that the PCB layout accommodates the slightly larger land size dimensions (0.287" L x 0.268" W vs. 0.260" L x 0.260" W) and the increased maximum seated height (0.315" vs. 0.307"). The identical capacitance, tolerance, operating temperature range, and package type (Radial, Can - SMD) ensure functional compatibility. Verify clearance to adjacent components and solder pad alignment before assembly.

Q2: What is the primary advantage of substituting with the ATB476M035?

A: The ATB476M035 provides three key improvements: (1) higher voltage rating (35 V vs. 25 V) for increased design margin, (2) lower ESR (3.95 Ohm vs. 5.64 Ohm @ 120Hz) for reduced heat generation, and (3) significantly higher ripple current capacity (196 mA vs. 65 mA @ 120 Hz) for applications requiring enhanced filtering performance.

Q3: Are there any compliance or regulatory differences between these parts?

A: No. Both the 476SVL025MEL and ATB476M035 are ROHS3 compliant, carry MSL 1 (unlimited moisture sensitivity), and are REACH unaffected. They are electrically and environmentally equivalent from a regulatory standpoint.

Q4: What is the impact of the different land sizes on PCB design?

A: The ATB476M035 requires a slightly larger surface mount land pattern (0.287" L x 0.268" W) compared to the 476SVL025MEL (0.260" L x 0.260" W). This difference is approximately 0.027" in length and 0.008" in width. PCB designs with tight component spacing must verify that the larger footprint does not create clearance conflicts with adjacent components or traces.

Q5: Can the 476SVL025MEL be used in applications originally designed for the ATB476M035?

A: No. The 476SVL025MEL has a lower voltage rating (25 V vs. 35 V) and lower ripple current capacity. Using it in place of the ATB476M035 would eliminate the voltage safety margin and may result in insufficient ripple current handling, creating reliability risks.

Q6: Are the thermal and lifetime characteristics identical between these parts?

A: Yes. Both parts have identical operating temperature ranges (-55°C to 105°C) and identical lifetime ratings (3000 Hrs @ 105°C), ensuring equivalent thermal performance and expected service life under the same operating conditions.
