Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the F971C106MBA is determined by the following critical parameters:

• Capacitance Value: Must be 10 µF (exact match required)
• Voltage Rating: Must be 16 V or higher (equal or greater acceptable)
• Package / Case: Must be 1411 (3528 Metric) for PCB compatibility
• Mounting Type: Must be Surface Mount
• Operating Temperature Range: Must support -55°C to 125°C minimum
• Type: Molded Tantalum construction
• RoHS Compliance: ROHS3 Compliant status required

Tolerance variations (±20% vs. ±10%) and ESR differences within the specified range do not prevent substitution when all critical parameters are met. Packaging format (Tape & Reel vs. Cut Tape) represents a supply chain variable and does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

F971C106KBA (KYOCERA AVX): This substitute maintains identical electrical and mechanical specifications to the main part with the exception of tolerance grade (±10% vs. ±20%). Both parts carry AEC-Q200 automotive qualification and identical MSL 3 moisture sensitivity ratings. Selection of this substitute is appropriate when tighter capacitance tolerance is required for circuit performance.

T491B106M016AT (KEMET): This substitute meets all critical electrical parameters (10 µF, 16 V, -55°C to 125°C operating range) and package requirements (1411 3528 Metric). The ESR specification is 2.5 Ohm compared to 2.1 Ohm in the main part. The seated height is 0.083" (2.10mm) versus 0.091" (2.30mm), representing a 0.008" reduction. MSL rating is 1 (Unlimited) versus MSL 3, indicating superior moisture resistance. This substitute is suitable for applications where lower moisture sensitivity is beneficial. The part carries ROHS3 compliance and is in active production status.

All three parts are currently in active production with full ROHS3 compliance and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can F971C106KBA replace F971C106MBA in automotive applications? A: Yes. Both parts carry AEC-Q200 qualification and identical operating temperature ranges (-55°C to 125°C). The primary difference is capacitance tolerance (±10% vs. ±20%), which represents improved precision rather than a limitation.

Q: What is the impact of the 0.4 Ohm ESR difference between F971C106MBA and T491B106M016AT? A: The T491B106M016AT has 2.5 Ohm ESR versus 2.1 Ohm in the main part. This 0.4 Ohm difference affects ripple current handling and heat dissipation characteristics. Circuit design must account for this specification when thermal or high-frequency performance is critical.

Q: Does the height difference between F971C106MBA (2.30mm) and T491B106M016AT (2.10mm) affect PCB assembly? A: No. Both parts use the same 1411 (3528 Metric) package footprint. The 0.20mm height reduction in the KEMET part does not impact PCB layout or component placement compatibility.

Q: What is the significance of MSL rating differences? A: F971C106MBA and F971C106KBA are rated MSL 3 (168 hours maximum floor life before reflow). T491B106M016AT is rated MSL 1 (unlimited floor life). MSL 1 provides greater flexibility in storage and handling without moisture bake-out requirements.

Q: Are packaging format differences (Tape & Reel vs. Cut Tape) relevant to substitution? A: No. Packaging format affects supply chain logistics and handling procedures only. Electrical and mechanical compatibility remain identical regardless of whether parts are supplied on Tape & Reel or Cut Tape.

Q: Can these substitutes be used interchangeably in the same circuit design? A: Yes, provided the circuit design accommodates the specified ESR and tolerance variations. All three parts meet the core electrical requirements (10 µF, 16 V, -55°C to 125°C) and mechanical compatibility (1411 package, surface mount).
