T520V477M2R5ASE009 Equivalent & Substitute Parts

Part Overview

The T520V477M2R5ASE009 is a 470 µF molded tantalum polymer capacitor rated at 2.5 V, manufactured by KEMET in the KO-CAP® T520 series. This component is designed for surface mount applications in the 2917 (7343 Metric) package format with an ESR of 9 mOhm at 100 kHz. The part is currently classified as obsolete, which necessitates identification of active equivalent alternatives to maintain design continuity and ensure supply chain availability for new production and repair applications.

Substitute Part Grouping Explanation

Substitution of the T520V477M2R5ASE009 is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Substitution Criteria:

• Capacitance value: 470 µF (exact match required)
• Voltage rating: 2.5 V (exact match required)
• ESR specification: 9 mOhm @ 100 kHz (exact match required)
• Package format: 2917 (7343 Metric) (exact match required)
• Tolerance: ±20% (exact match required)
• Operating temperature range: -55°C to 105°C (exact match required)
• Lifetime specification: 2000 Hrs @ 105°C (exact match required)
• Mounting type: Surface Mount (exact match required)
• MSL rating: 3 (168 Hours) (exact match required)

Two active substitute parts meet all electrical and mechanical equivalence criteria. These parts differ only in packaging configuration and product status compliance, not in functional performance or physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

T520V477M2R5ATE009 is the primary substitute for the obsolete T520V477M2R5ASE009. This part maintains full electrical and mechanical equivalence while offering active product status and ROHS3 compliance. The Cut Tape and Digi-Reel® packaging configuration provides flexibility for both small-quantity and production-volume applications.

T520V477M2R5ATE0097280 is the secondary substitute, offering identical electrical and mechanical specifications with active product status and ROHS3 compliance. This part is supplied in Tape & Reel (TR) format, optimized for high-volume automated assembly operations.

Both substitute parts eliminate the supply risk associated with the obsolete main part while providing improved regulatory compliance through ROHS3 certification. Selection between the two substitutes depends on packaging requirements and procurement volume.

Frequently Asked Questions (FAQ)

Q: Can T520V477M2R5ATE009 be used as a direct replacement for T520V477M2R5ASE009?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters, including capacitance, voltage rating, ESR, package dimensions, and operating characteristics. The primary difference is product status (active vs. obsolete) and RoHS compliance level.

Q: What is the difference between T520V477M2R5ATE009 and T520V477M2R5ATE0097280?

A: These parts are electrically and mechanically identical. The only difference is packaging configuration: T520V477M2R5ATE009 is supplied in Cut Tape and Digi-Reel® format, while T520V477M2R5ATE0097280 is supplied in Tape & Reel format. Selection depends on assembly equipment compatibility and order quantity requirements.

Q: Are the substitute parts compatible with existing PCB designs?

A: Yes. The substitute parts maintain identical package dimensions (2917 / 7343 Metric), height specifications (0.075" maximum seated height), and mounting type (surface mount). No PCB layout modifications are required.

Q: What is the significance of the RoHS compliance difference?

A: The main part (T520V477M2R5ASE009) is RoHS non-compliant, while both substitute parts (T520V477M2R5ATE009 and T520V477M2R5ATE0097280) are ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the substitute parts provide regulatory compliance.

Q: Do the substitute parts have the same thermal and electrical performance?

A: Yes. Both substitute parts maintain identical ESR (9 mOhm @ 100 kHz), operating temperature range (-55°C to 105°C), and lifetime specification (2000 Hrs @ 105°C). Thermal and electrical performance is equivalent to the main part.

Q: Which substitute should be selected for new production designs?

A: T520V477M2R5ATE009 is recommended for new designs due to active product status and flexible packaging options. T520V477M2R5ATE0097280 is suitable when high-volume Tape & Reel packaging is required for automated assembly.
