Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the F971A476MCC is determined by the following critical parameters:

• Capacitance Value: Must be 47 µF
• Voltage Rating: Must be 10 V or higher
• Package / Case: Must be 2312 (6032 Metric)
• Mounting Type: Must be Surface Mount
• Type: Must be Molded Tantalum

Secondary parameters that may vary within acceptable limits:

• Tolerance: Tighter tolerance (±10%) is acceptable as a substitute
• ESR: Variations within the same order of magnitude are acceptable depending on circuit requirements
• Manufacturer: Different manufacturers with equivalent specifications are acceptable

Parameter Comparison

Engineering Selection Recommendations

F971A476KCC (KYOCERA AVX): This part is a parametric equivalent with identical electrical characteristics to the main part, with the exception of tighter capacitance tolerance (±10% versus ±20%). Both parts share the same manufacturer, package, ESR specification, and compliance ratings. Selection of this part is appropriate when tighter tolerance specifications are required.

T491C476M010AT (KEMET): This part is a direct manufacturer equivalent with matching capacitance, voltage, tolerance, and package specifications. The primary difference is the ESR specification (1.2 Ohm versus 900 mOhm) and moisture sensitivity level (MSL 1 versus MSL 3). This part is suitable for applications where lower moisture sensitivity is beneficial. All parts maintain active production status and ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can F971A476KCC replace F971A476MCC in all applications?

A: Yes. F971A476KCC is a direct parametric equivalent with identical core specifications. The tighter tolerance (±10%) makes it suitable for all applications requiring the main part.

Q: What is the primary difference between F971A476MCC and T491C476M010AT?

A: Both parts share identical capacitance, voltage rating, tolerance, and package specifications. The T491C476M010AT has a higher ESR (1.2 Ohm versus 900 mOhm) and lower moisture sensitivity level (MSL 1 versus MSL 3). Selection depends on circuit requirements for ESR performance and handling conditions.

Q: Are all three parts in the same physical package?

A: Yes. All three parts use the 2312 (6032 Metric) surface mount package with identical dimensions: 0.236" L × 0.126" W (6.00 mm × 3.20 mm) and maximum seated height of 0.110" (2.80 mm).

Q: Do all substitute parts meet automotive qualification requirements?

A: F971A476MCC and F971A476KCC both carry AEC-Q200 automotive qualification. T491C476M010AT is rated for general purpose applications. Verify automotive qualification requirements for your specific application.

Q: What is the significance of the MSL rating difference?

A: F971A476MCC and F971A476KCC are rated MSL 3 (168 hours), requiring controlled moisture exposure during storage and handling. T491C476M010AT is rated MSL 1 (unlimited), allowing indefinite storage without moisture control measures.
