F931V685KCC Equivalent & Substitute Parts

Part Overview

The F931V685KCC is a 6.8 µF molded tantalum capacitor manufactured by KYOCERA AVX, rated for 35 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 ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified to provide design flexibility, support supply chain continuity, and accommodate component availability across multiple manufacturers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the F931V685KCC is determined by strict equivalence across the following parameters:

• Capacitance: 6.8 µF (exact match required)
• Voltage Rating: 35 V (exact match required)
• Tolerance: ±10% (exact match required)
• Package / Case: 2312 (6032 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• ESR: 1.8 Ohm (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All identified substitute parts meet these criteria. Substitutes are sourced from KYOCERA AVX (same manufacturer, different series), KEMET, and Vishay Sprague, each maintaining full electrical and mechanical compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain full electrical and mechanical compatibility with the F931V685KCC. Selection should be based on compliance requirements and product status:

For applications requiring ROHS3 compliance, the following parts are suitable: TAJC685K035RNJ (KYOCERA AVX TAJ series), 293D685X9035C2TE3 (Vishay Sprague 293D series), and T491C685K035AT (KEMET T491 series). All three are active products with ROHS3 certification.

The T491C685K035AH (KEMET T491 series) is RoHS non-compliant and should be selected only when legacy or non-compliant designs are specified.

The TAJC685K035RNJ offers same-manufacturer substitution within KYOCERA AVX's product portfolio, providing continuity with the original F93 series while maintaining identical electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can F931V685KCC be directly replaced with TAJC685K035RNJ?

A: Yes. Both parts are manufactured by KYOCERA AVX and share identical electrical parameters: 6.8 µF capacitance, 35 V rating, ±10% tolerance, 1.8 Ohm ESR, and 2312 package. The difference is series designation (F93 versus TAJ). Both are ROHS3 compliant and suitable for direct substitution.

Q: What is the difference between T491C685K035AT and T491C685K035AH?

A: Both are KEMET T491 series parts with identical electrical specifications. The primary difference is RoHS compliance: T491C685K035AT is ROHS3 compliant, while T491C685K035AH is RoHS non-compliant. Select T491C685K035AT for new designs requiring compliance certification.

Q: Are all substitute parts available in the same package dimensions?

A: Yes. All substitute parts use the 2312 (6032 Metric) surface mount package with identical footprint dimensions: 0.236" L × 0.126" W (6.00mm × 3.20mm). Maximum seated height is 0.110" (2.80mm) for all parts, with negligible variation (2.79mm for Vishay part).

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. All parts share identical mounting type (surface mount), package footprint, and lead spacing. No PCB layout modifications are required for substitution.

Q: Which substitute offers the best supply availability?

A: The 293D685X9035C2TE3 (Vishay Sprague) currently has the highest inventory level at 10,989 pieces. TAJC685K035RNJ (KYOCERA AVX) has 2,542 pieces available.
