Substitute Part Grouping Explanation

Substitute parts for the F971V475MCC are identified based on strict electrical and mechanical compatibility criteria:

Parametric Equivalent (Same Manufacturer - KYOCERA AVX): The F971V475KCC maintains identical capacitance (4.7 µF), voltage rating (35 V), package (2312), ESR (1.8 Ohm), and operating temperature range. The primary difference is tolerance specification (±10% versus ±20%), which represents improved precision. This part qualifies as a direct parametric equivalent with enhanced tolerance performance.

Direct Manufacturer Equivalent (Different Manufacturer - KEMET): The T491C475M035AT from KEMET matches the core electrical specifications: 4.7 µF capacitance, 35 V rating, ±20% tolerance, and 2312 package. The ESR is specified at 2.2 Ohm (versus 1.8 Ohm for the main part) and MSL rating differs (1 versus 3). Both parts are ROHS3 compliant and rated for the same operating temperature range, enabling cross-manufacturer substitution where ESR and moisture sensitivity variations are acceptable.

Parameter Comparison

Engineering Selection Recommendations

F971V475KCC Selection Criteria: Select the F971V475KCC when improved capacitance tolerance (±10%) is required within the same manufacturer ecosystem. This part maintains identical ESR and moisture sensitivity specifications, ensuring direct functional compatibility with no design modifications. Both KYOCERA AVX parts carry AEC-Q200 automotive qualification and ROHS3 compliance.

T491C475M035AT Selection Criteria: Select the T491C475M035AT when cross-manufacturer sourcing is necessary and ESR variation of 0.4 Ohm is acceptable within circuit design margins. This KEMET part offers superior moisture sensitivity (MSL 1 versus MSL 3), reducing handling and storage constraints. The part is ROHS3 compliant and rated for identical operating temperature range. Verify ESR impact on circuit performance before substitution, as the 2.2 Ohm specification differs from the 1.8 Ohm main part.

Frequently Asked Questions (FAQ)

Q: Can F971V475KCC be used as a direct replacement for F971V475MCC? A: Yes. Both parts are manufactured by KYOCERA AVX with identical capacitance (4.7 µF), voltage rating (35 V), package (2312), ESR (1.8 Ohm), and operating temperature range. The F971V475KCC offers tighter tolerance (±10% versus ±20%), making it functionally compatible with no design changes required.

Q: What are the key differences between F971V475MCC and T491C475M035AT? A: Both parts share 4.7 µF capacitance, 35 V rating, ±20% tolerance, and 2312 package. Differences include: manufacturer (KYOCERA AVX versus KEMET), ESR (1.8 Ohm versus 2.2 Ohm), and MSL rating (3 versus 1). The T491C475M035AT has superior moisture sensitivity performance.

Q: Is ESR difference between F971V475MCC (1.8 Ohm) and T491C475M035AT (2.2 Ohm) significant? A: ESR impact depends on circuit application. The 0.4 Ohm difference represents approximately 22% higher ESR in the KEMET part. For ripple current filtering and transient response applications, verify that the higher ESR remains within design specifications before substitution.

Q: Are all three parts ROHS3 compliant? A: Yes. F971V475MCC, F971V475KCC, and T491C475M035AT are all ROHS3 compliant and suitable for applications requiring environmental compliance certification.

Q: What is the significance of MSL rating differences? A: F971V475MCC and F971V475KCC are rated MSL 3 (168 hours), requiring controlled moisture exposure during storage and handling. T491C475M035AT is rated MSL 1 (unlimited), eliminating moisture sensitivity constraints. MSL 1 parts offer greater flexibility in supply chain management and storage conditions.

Q: Can these parts be used interchangeably in automotive applications? A: F971V475MCC and F971V475KCC are both AEC-Q200 qualified for automotive use. T491C475M035AT is not specified with AEC-Q200 qualification in the provided data. Verify automotive qualification requirements before substituting the KEMET part in automotive designs.
