Substitute Part Grouping Explanation

Substitution eligibility for the T54EE476M035CSS070 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 47 µF (exact match required)
• Voltage Rating: 35 V (exact match required)
• ESR Specification: 70 mOhm @ 100kHz (exact match required)
• Package Format: 2917 (7343 Metric) (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Mounting Technology: Surface Mount (exact match required)
• Manufacturer Series: vPolyTan™ T54 (exact match required)
• Product Status: Active (current production required)
• Compliance: ROHS3 Compliant (exact match required)

The substitute part T54EE476M035CSA070 meets all these criteria and is therefore classified as a parametric equivalent. Both parts share identical electrical performance characteristics, mechanical dimensions, and environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the T54EE476M035CSS070 and T54EE476M035CSA070 are active production components from Vishay Polytech with full ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts is based on availability and procurement requirements rather than technical differentiation.

The T54EE476M035CSA070 currently maintains higher inventory levels (1771 Pcs) compared to the T54EE476M035CSS070 (1057 Pcs), making it suitable for applications where supply chain continuity is a priority. Both parts are certified for COTS (Commercial Off-The-Shelf) applications and carry identical reliability ratings.

For applications requiring tantalum polymer capacitors with 47 µF capacitance, 35 V rating, and low ESR characteristics in the 2917 package format, either part number satisfies the technical requirements without modification to circuit design or PCB layout.

Frequently Asked Questions (FAQ)

Q: Can T54EE476M035CSA070 be used as a direct replacement for T54EE476M035CSS070?

A: Yes. Both parts are parametric equivalents with identical capacitance, voltage rating, ESR, package dimensions, and operating specifications. No circuit modifications or PCB layout changes are required for substitution.

Q: Are there any differences in the 2917 package dimensions between these parts?

A: No. Both parts use the identical 2917 (7343 Metric) package with dimensions of 0.287" L x 0.169" W (7.30mm x 4.30mm) and maximum seated height of 0.169" (4.30mm). PCB footprints are interchangeable.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both parts are ROHS3 compliant, carry MSL rating of 3 (168 Hours), and are rated for operation across -55°C to 125°C with 2000 hours lifetime at 125°C.

Q: What is the significance of the different part number suffixes (CSS070 vs. CSA070)?

A: The suffix variation reflects internal Vishay manufacturing or packaging designations. Both suffixes indicate identical electrical performance and mechanical specifications within the vPolyTan™ T54 series.

Q: Are these parts suitable for high-reliability applications?

A: Yes. Both parts carry high reliability ratings and COTS certification, making them suitable for applications requiring proven component performance and traceability.

Q: What is the ESR specification and why is it important?

A: Both parts specify 70 mOhm ESR at 100kHz. ESR directly affects ripple current handling, thermal performance, and frequency response in power supply and filtering applications. The identical ESR ensures equivalent circuit performance.
