F931A476KCC Equivalent & Substitute Parts

Part Overview

The F931A476KCC is a 47 µF molded tantalum capacitor manufactured by KYOCERA AVX, rated for 10 V operation in a 2312 (6032 Metric) surface mount package. This component is designed for general-purpose applications requiring stable capacitance and low equivalent series resistance in compact form factors. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across alternative manufacturers.

Substitute Part Grouping Explanation

Substitution of the F931A476KCC is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 47 µF (exact match required)
• Voltage Rating: 10 V (exact match required)
• Tolerance: ±10% (exact match required)
• Package / Case: 2312 (6032 Metric) (exact match required for PCB compatibility)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Lifetime @ 125°C: 2000 Hrs (exact match required)
• Type: Molded Tantalum (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The KEMET T491C476K010AT meets all substitution criteria as a direct equivalent. Variations in ESR (Equivalent Series Resistance) are permitted within the molded tantalum capacitor category, as this parameter does not affect mechanical interchangeability or core electrical performance for general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

Both the F931A476KCC and T491C476K010AT are active production components with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on supply chain availability and ESR performance requirements. The F931A476KCC exhibits lower ESR at 900 mOhm compared to the T491C476K010AT at 1.2 Ohm, which may be relevant for applications with stringent ripple current or thermal dissipation constraints. Both parts maintain identical electrical ratings, temperature performance, and mechanical compatibility for direct PCB substitution.

Frequently Asked Questions (FAQ)

Q: Can the T491C476K010AT replace the F931A476KCC in production? A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters including capacitance, voltage rating, package dimensions, and temperature performance. Direct substitution on PCB assemblies is supported.

Q: Does the difference in ESR affect compatibility? A: ESR variation between 900 mOhm and 1.2 Ohm is within normal manufacturing tolerance for molded tantalum capacitors. For general-purpose applications, this difference does not impact functional compatibility. Applications with specific ESR requirements should be evaluated against circuit performance specifications.

Q: Are both parts suitable for the same operating temperature range? A: Yes. Both the F931A476KCC and T491C476K010AT operate across -55°C to 125°C with identical 2000-hour lifetime ratings at 125°C.

Q: Is the 2312 package footprint identical between manufacturers? A: Yes. Both parts use the 2312 (6032 Metric) package with identical dimensions: 0.236" L x 0.126" W (6.00mm x 3.20mm) and maximum seated height of 0.110" (2.80mm). PCB footprints are directly interchangeable.

Q: Do both parts meet current regulatory requirements? A: Yes. Both the F931A476KCC and T491C476K010AT are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing and use.
