Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the F971C106MBAHT3 are identified based on the following critical parameters that must remain constant or compatible:

• Capacitance: 10 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Package / Case: 1411 (3528 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Physical Dimensions: 0.138" L x 0.110" W, Height 0.083" max (exact match required)
• Type: Molded Tantalum (exact match required)

The substitute parts listed below maintain these core parameters. Variations in voltage rating, ESR, operating temperature range, and MSL are permitted within the constraints of the application circuit design, as these parameters do not affect physical compatibility or basic capacitive function when the circuit voltage rating is respected.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory conformance. The F971C106MBAHT3 carries AEC-Q200 automotive qualification and high-reliability designation; substitute parts from KEMET (T489B106M006ATE3K0 and T491B106M006AT) are general-purpose rated components. Selection between substitute parts should account for application voltage requirements, as both KEMET alternatives are rated for 6.3 V operation, which is lower than the main part's 16 V rating. The main part's superior ESR (2.1 Ohm) and extended operating temperature range (-55°C to 135°C) reflect its automotive-grade specification. Substitute parts offer improved moisture sensitivity characteristics (MSL 1 vs. MSL 3), which may provide handling advantages in certain manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can T489B106M006ATE3K0 or T491B106M006AT be used as direct replacements for F971C106MBAHT3?

A: Physical and electrical compatibility is maintained for capacitance, tolerance, package, and mounting type. However, the voltage rating difference (6.3 V vs. 16 V) requires circuit-level evaluation. Substitution is valid only if the application circuit operates at or below 6.3 V.

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

A: The F971C106MBAHT3 is rated for 16 V operation, while both KEMET substitutes are rated for 6.3 V. A component must never be operated above its rated voltage. If your circuit requires 16 V rated capacitance, the main part is the appropriate selection.

Q: How do ESR differences affect circuit performance?

A: The main part exhibits 2.1 Ohm ESR compared to 3 Ohm (T489B106M006ATE3K0) and 4.6 Ohm (T491B106M006AT) for substitutes. Higher ESR increases impedance and heat generation in high-frequency or high-current applications. Circuit design must accommodate these differences.

Q: What does MSL 3 vs. MSL 1 mean for handling?

A: MSL 3 (168 Hours) indicates the main part requires reflow processing within 168 hours of moisture exposure. MSL 1 (Unlimited) substitutes have no time restriction, simplifying inventory and assembly logistics.

Q: Are the KEMET substitutes suitable for automotive applications?

A: The KEMET parts are classified as general-purpose components without AEC-Q200 qualification. The main part's automotive and high-reliability ratings are not replicated in the substitutes. Application requirements must determine acceptability.

Q: What is the difference between T489B106M006ATE3K0 and T491B106M006AT packaging?

A: T489B106M006ATE3K0 is supplied in Tape & Reel (TR) packaging, while T491B106M006AT is supplied in Cut Tape (CT) & Digi-Reel® packaging. Both are surface mount compatible; packaging selection depends on assembly equipment and volume requirements.
