Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAJC685K020SNJ is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Capacitance value: 6.8 µF (derived from part number designation)
• Voltage rating: 20 V (derived from part number designation)
• Tolerance: ±10% (standard for this series)
• Component type: Molded tantalum capacitor

Mechanical Compatibility Criteria:

• Packaging format: Tape & Reel (TR) surface mount
• Package case: 2312 (6032 Metric) form factor
• Mounting type: Surface Mount

Regulatory & Compliance Criteria:

• RoHS3 compliance required
• Moisture Sensitivity Level 1 (unlimited)
• REACH unaffected status
• EAR99 export classification

The substitute part 293D685X9020C2TE3 (Vishay Sprague TANTAMOUNT™ series) satisfies all electrical, mechanical, and regulatory requirements for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (TAJC685K020SNJ): The KYOCERA AVX TAJC685K020SNJ maintains active product status with established supply availability (856 units in stock). This part is suitable for new designs and ongoing production where KYOCERA AVX qualification is specified or preferred.

Substitute Selection (293D685X9020C2TE3): The Vishay Sprague 293D685X9020C2TE3 provides equivalent electrical and mechanical performance with documented ESR specification (1.9 Ohm) and operating temperature range (-55°C ~ 125°C). This substitute is appropriate for supply chain continuity, design flexibility, or when Vishay Sprague components are preferred. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and EAR99 classification, ensuring regulatory equivalence.

Compliance Verification: Both parts satisfy ROHS3 requirements, Moisture Sensitivity Level 1 (unlimited handling), and REACH unaffected status. No additional compliance screening is required for direct substitution in existing designs.

Frequently Asked Questions (FAQ)

Q: Can 293D685X9020C2TE3 be used as a direct replacement for TAJC685K020SNJ?

A: Yes. Both parts share identical electrical specifications (6.8 µF, 20 V, ±10% tolerance), mechanical form factor (2312/6032 Metric), surface mount packaging, and regulatory compliance (ROHS3, REACH unaffected, EAR99). Direct substitution is supported without circuit modification.

Q: Are there differences in ESR or performance characteristics?

A: The Vishay Sprague substitute specifies 1.9 Ohm ESR and -55°C ~ 125°C operating temperature. The KYOCERA AVX part does not provide these specifications in the available data. If ESR or temperature performance is critical to circuit design, verify the KYOCERA AVX specification sheet or conduct comparative testing.

Q: Do both parts require identical PCB footprints?

A: Yes. Both parts use the 2312 (6032 Metric) package case with identical surface mount footprint requirements. No PCB layout changes are necessary for substitution.

Q: Are there supply or lead time considerations?

A: Current inventory shows 856 units of TAJC685K020SNJ and 1540 units of 293D685X9020C2TE3 in stock. The Vishay Sprague substitute offers higher immediate availability.

Q: What is the significance of Moisture Sensitivity Level 1?

A: MSL 1 (unlimited) indicates the component has no moisture sensitivity restrictions. Standard storage and handling procedures apply without special desiccant or baking requirements prior to soldering.

Q: Are export or trade restrictions different between these parts?

A: No. Both parts carry EAR99 classification and HTSUS code 8532.21.0050, indicating identical export and tariff treatment.
