F971C336MBA Equivalent & Substitute Parts

Part Overview

The F971C336MBA is a 33 µF molded tantalum capacitor manufactured by KYOCERA AVX, rated for 16 V operation in a 1411 (3528 Metric) surface mount package. This component is designed for automotive and high-reliability applications with AEC-Q200 qualification. The part is currently in active production status with ROHS3 compliance and automotive-grade reliability features. Substitute parts are identified when equivalent electrical and mechanical specifications are required for design flexibility, inventory management, or supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the F971C336MBA is determined by strict equivalence across the following critical parameters:

• Capacitance value: 33 µF (exact match required)
• Voltage rating: 16 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package / Case: 1411 (3528 Metric) (exact match required)
• ESR: 2.1 Ohm (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)
• Mounting type: Surface Mount (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

Two substitute parts meet these criteria: F971C336MBAHT3 (KYOCERA AVX) and T491B336M016AT (KEMET). Both parts maintain identical electrical performance and physical form factor compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status and ROHS3 compliance. The F971C336MBA and F971C336MBAHT3 are both KYOCERA AVX products with AEC-Q200 automotive qualification. The T491B336M016AT is a KEMET equivalent with general purpose classification and superior moisture sensitivity rating (MSL 1 versus MSL 3).

Height differences exist between the main part (0.091" / 2.30mm) and both substitutes (0.083" / 2.10mm). This reduced height may provide design advantages in space-constrained applications but requires PCB layout verification for clearance compatibility.

Selection should be based on supply availability, lead time requirements, and specific application constraints. All three parts satisfy the core electrical and mechanical specifications for direct substitution in 33 µF, 16 V tantalum capacitor applications.

Frequently Asked Questions (FAQ)

Q: Can F971C336MBAHT3 be used as a direct replacement for F971C336MBA?

A: Yes. Both parts are manufactured by KYOCERA AVX with identical electrical specifications (33 µF, 16 V, ±20%, 2.1 Ohm ESR), package type (1411 / 3528 Metric), and AEC-Q200 qualification. The F971C336MBAHT3 has a reduced seated height (0.083" versus 0.091"), which must be verified for PCB layout compatibility.

Q: What are the differences between the KYOCERA AVX and KEMET substitutes?

A: The T491B336M016AT (KEMET) matches all critical electrical and mechanical parameters. Key differences are manufacturer identity, moisture sensitivity level (MSL 1 for KEMET versus MSL 3 for KYOCERA AVX), and application classification (general purpose versus automotive). Both parts are ROHS3 compliant and operate across the same temperature range.

Q: Does the height difference between parts affect PCB design?

A: The main part (F971C336MBA) has a maximum seated height of 0.091" (2.30mm), while both substitutes measure 0.083" (2.30mm). This 0.008" (0.20mm) reduction requires verification against PCB clearance requirements, component placement density, and any height-sensitive mechanical constraints in the assembly.

Q: Are all three parts suitable for automotive applications?

A: The F971C336MBA and F971C336MBAHT3 carry AEC-Q200 automotive qualification. The T491B336M016AT is classified as general purpose. For applications requiring automotive-grade reliability certification, the KYOCERA AVX parts are the appropriate selection.

Q: What is the moisture sensitivity level (MSL) significance?

A: MSL indicates the maximum time a component can be exposed to ambient conditions before soldering. The F971C336MBA and F971C336MBAHT3 have MSL 3 (168 hours maximum), while the T491B336M016AT has MSL 1 (unlimited exposure). Lower MSL values provide greater handling flexibility in manufacturing environments.
