F930J686MCC Equivalent & Substitute Parts

Part Overview

The F930J686MCC is a 68 µF molded tantalum capacitor manufactured by KYOCERA AVX, rated for 6.3 V operation in a 2312 (6032 Metric) surface mount package. This component is designed for general-purpose applications requiring stable capacitance in compact form factors. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical specifications can be maintained across alternative manufacturers while preserving functional performance in target applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the F930J686MCC is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 68 µF (exact match required)
• Voltage Rating: 6.3 V (exact match required)
• Package / Case: 2312 (6032 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (minimum requirement)
• Type: Molded Tantalum (exact match required)

Allowable Variation Parameters:

• Tolerance: ±20% or tighter (±10% acceptable as improvement)
• ESR: Specification provided or unspecified (lower ESR acceptable)
• RoHS / Compliance: ROHS3 Compliant (maintained across all substitutes)
• MSL Rating: 1 (Unlimited) (maintained across all substitutes)

The substitute part 293D686X96R3C2TE3 (Vishay Sprague) qualifies as a direct equivalent because it maintains all mandatory parameters while offering improved tolerance specification (±10% versus ±20%) and defined ESR performance (800 mOhm).

Parameter Comparison

Engineering Selection Recommendations

Both the F930J686MCC and 293D686X96R3C2TE3 maintain Active product status with full regulatory compliance (ROHS3, REACH Unaffected, EAR99 classification). The substitute part offers tighter tolerance specification (±10% versus ±20%) and explicit ESR definition (800 mOhm), which may provide improved performance predictability in applications sensitive to capacitance variation or impedance characteristics. Physical dimensions and thermal operating range are equivalent. Selection between these parts should be based on application-specific tolerance requirements, supply chain availability, and cost considerations. Both parts are suitable for direct substitution in 6.3 V, 68 µF tantalum capacitor applications using 2312 surface mount packaging.

Frequently Asked Questions (FAQ)

Q: Can the 293D686X96R3C2TE3 be used as a direct replacement for the F930J686MCC?

A: Yes. Both parts share identical capacitance (68 µF), voltage rating (6.3 V), package type (2312 / 6032 Metric), and operating temperature range (-55°C ~ 125°C). The substitute offers improved tolerance (±10% versus ±20%) and specified ESR performance.

Q: What is the significance of the tolerance difference between ±20% and ±10%?

A: Tolerance defines the allowable deviation of actual capacitance from the nominal 68 µF value. The ±10% specification on the substitute part provides a narrower acceptable range, resulting in more predictable capacitance values across production batches. Applications requiring tighter capacitance control benefit from this specification.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 2312 (6032 Metric) package with dimensions of 0.236" L x 0.126" W (6.00mm x 3.20mm). Maximum seated height is 0.110" (2.80mm for F930J686MCC, 2.79mm for 293D686X96R3C2TE3), representing negligible difference suitable for PCB layout compatibility.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both parts are ROHS3 Compliant, REACH Unaffected, and classified as EAR99. Both carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture handling requirements during storage or assembly.

Q: What does ESR (Equivalent Series Resistance) mean in this context?

A: ESR represents the internal resistance of the capacitor at operating frequency. The substitute part specifies 800 mOhm ESR, while the main part does not provide this specification. Lower ESR generally indicates better high-frequency performance and reduced heat generation under AC conditions.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the application does not require the specific tolerance or ESR characteristics of one part over the other. Both parts are mechanically and electrically compatible for 6.3 V, 68 µF tantalum capacitor applications in 2312 surface mount configuration.
