F971C226MCC Equivalent & Substitute Parts

Part Overview

The F971C226MCC is a 22 µF molded tantalum capacitor manufactured by KYOCERA AVX, rated for 16 V operation in a 2312 (6032 Metric) surface mount package. This component is designed for applications requiring reliable energy storage with automotive-grade reliability and high-temperature stability across the -55°C to 125°C operating range. The part maintains Active product status with full RoHS3 compliance and AEC-Q200 automotive qualification. Substitute parts are identified to provide design flexibility when primary sourcing is constrained or when alternative electrical characteristics better suit specific application requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the F971C226MCC is determined by strict equivalence across the following parameters:

• Capacitance value: 22 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage rating: 16 V (exact match required)
• Package / Case: 2312 (6032 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Type: Molded Tantalum (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The T491C226M016AT from KEMET meets all substitution criteria. Variations in ESR (Equivalent Series Resistance), MSL rating, and lifetime specifications do not disqualify substitution eligibility when all primary electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

Both the F971C226MCC and T491C226M016AT are Active product status components with full RoHS3 compliance and REACH unaffected status, making them suitable for equivalent selection in regulated applications. The F971C226MCC carries AEC-Q200 automotive qualification and high-reliability designation, establishing it as the primary choice for automotive and mission-critical applications. The T491C226M016AT provides an alternative source with equivalent electrical and mechanical specifications. Selection between these parts should be based on supply availability, cost considerations, and application-specific requirements for ESR performance and moisture sensitivity tolerance.

Frequently Asked Questions (FAQ)

Q: Can T491C226M016AT replace F971C226MCC in automotive applications?

A: Both parts meet the same electrical specifications (22 µF, ±20%, 16 V) and package requirements (2312 / 6032 Metric). The F971C226MCC carries explicit AEC-Q200 automotive qualification. Application suitability depends on whether your design specifically requires AEC-Q200 certification or if general ROHS3 compliance is sufficient.

Q: What is the significance of the ESR difference (1.1 Ohm vs. 1.5 Ohm)?

A: ESR affects ripple current handling and heat dissipation characteristics. The F971C226MCC exhibits lower ESR at 1.1 Ohm compared to the T491C226M016AT at 1.5 Ohm. For applications with high ripple current requirements, verify that the substitute part's ESR remains within acceptable limits for your circuit design.

Q: Are the physical dimensions identical?

A: Yes. Both parts are packaged in 2312 (6032 Metric) with identical dimensions of 0.236" L x 0.126" W (6.00mm x 3.20mm) and maximum seated height of 0.110" (2.80mm), ensuring direct PCB footprint compatibility.

Q: What is the difference in Moisture Sensitivity Level (MSL)?

A: The F971C226MCC is rated MSL 3 (168 Hours), while the T491C226M016AT is rated MSL 1 (Unlimited). MSL 1 indicates superior moisture resistance and longer shelf life without baking requirements. This difference does not affect substitution eligibility but may influence storage and handling procedures.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the F971C226MCC and T491C226M016AT are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
