Substitute Part Grouping Explanation

Substitute parts for the T520D157M010ATE0402478 are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

• Capacitance value: 150 µF (exact match required)
• Voltage rating: 10 V (exact match required)
• ESR specification: 40 mOhm @ 100 kHz (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Operating temperature range: -55°C ~ 105°C (exact match required)
• Tolerance: ±20% (exact match required)

All identified substitute parts meet these parameters and are qualified for direct replacement in applications originally designed for the T520D157M010ATE0402478.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with matching electrical and mechanical specifications. Selection between the main part and substitutes should be based on the following factors:

For applications requiring RoHS3 compliance, T520D157M010ATE0402478, T520D157M010ATE040, and TCJD157M010R0040 are suitable options. The T520D157M010AHE040 is RoHS non-compliant and should be selected only when regulatory requirements do not mandate RoHS3 compliance.

For KEMET-specific supply chain requirements, both T520D157M010ATE0402478 and T520D157M010ATE040 are available. The TCJD157M010R0040 from KYOCERA AVX provides cross-manufacturer equivalence while maintaining identical electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can T520D157M010AHE040 be used as a direct replacement for T520D157M010ATE0402478?

A: T520D157M010AHE040 meets all electrical and mechanical parameters but differs in RoHS compliance status. It is a direct functional equivalent only for applications where RoHS3 compliance is not required.

Q: What is the difference between T520D157M010ATE0402478 and T520D157M010ATE040?

A: Both parts are electrically and mechanically identical. The difference lies in the packaging designation suffix. Both are RoHS3 compliant and active products from KEMET.

Q: Is TCJD157M010R0040 from KYOCERA AVX fully compatible with the KEMET T520D157M010ATE0402478?

A: Yes. TCJD157M010R0040 matches all critical electrical parameters (150 µF, 10 V, 40 mOhm ESR), mechanical specifications (2917 package), and compliance requirements (RoHS3). It is a qualified cross-manufacturer substitute.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts are supplied in Tape & Reel (TR) packaging and use the identical 2917 (7343 Metric) surface mount package.

Q: What determines whether a part can substitute for T520D157M010ATE0402478?

A: Substitution is determined by exact matching of capacitance (150 µF), voltage rating (10 V), ESR specification (40 mOhm @ 100 kHz), package format (2917), mounting type (Surface Mount), operating temperature range (-55°C ~ 105°C), and tolerance (±20%).
