Key Parameters

Substitute Part Grouping Explanation

Substitution of the T520D477M2R5ASE009 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 470 µF
• Voltage Rating: 2.5 V
• Package / Case: 2917 (7343 Metric)
• ESR: 9 mOhm @ 100 kHz
• Operating Temperature Range: -55°C to 105°C
• Lifetime @ 105°C: 2000 Hours
• Tolerance: ±20%
• Mounting Type: Surface Mount

Allowable Variations:

• Manufacturer (KEMET or Panasonic Electronic Components)
• Packaging format (Tape & Reel, Cut Tape & Digi-Reel®)
• Product status (Active substitutes preferred over obsolete)
• RoHS compliance status (ROHS3 Compliant substitutes available)
• Height - Seated (within mechanical envelope constraints)
• Manufacturer size code designation

The substitute parts identified maintain electrical equivalence while offering improved product status and compliance certifications compared to the obsolete main part number.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: T520D477M2R5ATE009

The T520D477M2R5ATE009 is the direct KEMET equivalent with active product status and ROHS3 compliance. This part maintains identical electrical specifications and the same seated height (0.122" / 3.10 mm) as the obsolete T520D477M2R5ASE009, ensuring mechanical compatibility within existing PCB designs. Packaging is available in Tape & Reel format with 1180 pieces in stock.

Secondary Recommendation: T520V477M2R5ATE009

The T520V477M2R5ATE009 offers active product status and ROHS3 compliance with identical electrical performance. This variant features a reduced seated height of 0.075" (1.90 mm), which provides design flexibility for space-constrained applications. Packaging is available in Cut Tape & Digi-Reel® format with 1610 pieces in stock. Height reduction must be verified for mechanical clearance in existing designs.

Tertiary Recommendation: T520V477M2R5ATE0097280

The T520V477M2R5ATE0097280 provides the same electrical specifications and reduced height profile as the T520V477M2R5ATE009, with active product status and ROHS3 compliance. This part is supplied in Tape & Reel packaging with 842 pieces in stock. Height compatibility assessment is required for existing designs.

Alternative Manufacturer Option: 2R5TPE470M9

The 2R5TPE470M9 from Panasonic Electronic Components (POSCAP™ TPE series) delivers electrical equivalence with active product status and ROHS3 compliance. This part features a seated height of 0.079" (2.00 mm) and is available in Cut Tape & Digi-Reel® packaging with 27200 pieces in stock. Cross-manufacturer substitution requires verification of thermal and reliability performance in the target application.

Compliance Consideration:

All recommended substitutes are ROHS3 compliant, addressing regulatory requirements that the obsolete T520D477M2R5ASE009 does not meet. Selection should prioritize active product status to ensure long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the T520D477M2R5ATE009 directly replace the T520D477M2R5ASE009 in existing designs?

A: Yes. The T520D477M2R5ATE009 maintains identical electrical specifications (470 µF, 2.5 V, 9 mOhm ESR) and mechanical dimensions (0.122" seated height) as the obsolete part. The primary difference is active product status and ROHS3 compliance. No design modifications are required.

Q: What is the difference between the T520D and T520V variants?

A: The T520D and T520V designations indicate different manufacturer size codes. The T520V variant features a reduced seated height of 0.075" (1.90 mm) compared to the T520D at 0.122" (3.10 mm). All other electrical parameters remain identical. Height compatibility with existing PCB designs must be verified before substitution.

Q: Why is the 2R5TPE470M9 from Panasonic listed as an alternative?

A: The 2R5TPE470M9 meets all mandatory electrical equivalence criteria: 470 µF capacitance, 2.5 V rating, 9 mOhm ESR, 2917 package, and identical operating temperature range. Cross-manufacturer substitution is electrically valid but requires application-specific verification of thermal performance and reliability characteristics.

Q: What does ROHS3 compliance mean for this capacitor?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, hexavalent chromium, and specific brominated flame retardants. The obsolete T520D477M2R5ASE009 is RoHS non-compliant. All recommended substitutes are ROHS3 compliant, supporting regulatory requirements in regulated markets.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR) and Cut Tape & Digi-Reel® packaging formats do not affect electrical specifications. Selection is based on manufacturing process requirements and inventory management. Tape & Reel is standard for high-volume automated assembly; Cut Tape & Digi-Reel® supports lower-volume or mixed-component operations.

Q: Are there any height restrictions for the T520V variants in my design?

A: The T520V variants (T520V477M2R5ATE009 and T520V477M2R5ATE0097280) feature a seated height of 0.075" (1.90 mm), compared to 0.122" (3.10 mm) for the T520D variant. If your PCB design includes height-constrained areas (such as under low-profile connectors or shielding), the reduced height may provide design advantages. Verify clearance requirements before substitution.

Q: What is the Moisture Sensitivity Level (MSL) and why does it matter?

A: MSL 3 indicates the component requires protection from moisture exposure for up to 168 hours at specified temperature and humidity conditions before soldering. All KEMET substitutes maintain MSL 3 rating. Proper storage in dry conditions and adherence to IPC-A-610 handling procedures are required to prevent moisture-induced failures during assembly.

Q: Can I mix different substitute parts in the same production run?

A: All identified substitutes are electrically equivalent and mechanically compatible within their respective height specifications. However, mixing different part numbers in a single production run introduces supply chain complexity and potential traceability issues. Standardization on a single substitute part number is recommended for manufacturing consistency.
