T322C685K025AS Equivalent & Substitute Parts

Part Overview

The T322C685K025AS is a 6.8 µF molded tantalum capacitor manufactured by KEMET, rated for 25 V operation in an axial through-hole configuration. This component belongs to the T322 series and is classified as general purpose. The part is currently active in production with 653 units in stock.

Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when design requirements mandate specific compliance certifications, or when inventory constraints require alternative sourcing from the same manufacturer's product line.

Substitute Part Grouping Explanation

Substitution eligibility for the T322C685K025AS is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Electrical Parameters (Non-negotiable):

• Capacitance value: 6.8 µF
• Voltage rating: 25 V
• Tolerance: ±10%
• ESR: 3.1 Ohm
• Operating temperature range: -55°C to 125°C

Mechanical Parameters (Non-negotiable):

• Mounting type: Through hole axial
• Package dimensions: 0.180" Dia × 0.345" L (4.57mm × 8.76mm)
• Manufacturer size code: C

Acceptable Variations:

• RoHS compliance status (both RoHS non-compliant and ROHS3 compliant versions are functionally equivalent)
• Packaging format (bulk packaging acceptable)
• Inventory availability

The T322C685K025AT qualifies as a direct substitute based on complete parameter alignment across all electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (T322C685K025AS): Select this part number when RoHS non-compliant components are acceptable for your application and when the existing inventory of 653 units meets project requirements.

Alternative Selection (T322C685K025AT): Select this part number when ROHS3 compliance is mandated by design specifications, procurement policies, or end-use regulations. The T322C685K025AT provides superior inventory availability with 867 units in stock and maintains complete electrical and mechanical equivalence to the primary part.

Both part numbers are manufactured by KEMET, carry active product status, and are suitable for direct substitution in through-hole axial tantalum capacitor applications requiring 6.8 µF at 25 V with ±10% tolerance.

Frequently Asked Questions (FAQ)

Q: Can T322C685K025AT be used as a direct replacement for T322C685K025AS on existing PCBs?

A: Yes. Both parts are identical in all electrical parameters (capacitance, voltage, tolerance, ESR, temperature range) and mechanical specifications (axial through-hole mounting, 0.180" Dia × 0.345" L dimensions). Physical PCB compatibility is guaranteed.

Q: What is the difference between these two part numbers?

A: The primary difference is RoHS compliance status. T322C685K025AS is RoHS non-compliant, while T322C685K025AT is ROHS3 compliant. All other specifications are identical.

Q: Which part should I specify for new designs?

A: Specify T322C685K025AT for new designs unless RoHS exemption is explicitly documented. This part offers better long-term availability (867 units in stock versus 653) and meets current regulatory compliance standards.

Q: Are there any performance differences between these parts?

A: No. Both parts deliver identical electrical performance with 6.8 µF capacitance, 25 V rating, ±10% tolerance, and 3.1 Ohm ESR across the -55°C to 125°C operating range.

Q: Can I mix these part numbers in the same assembly?

A: Yes. Since all electrical and mechanical parameters are identical, mixing T322C685K025AS and T322C685K025AT in the same assembly presents no functional or compatibility issues.

Q: What does the "C" manufacturer size code indicate?

A: The "C" size code is KEMET's designation for the physical package dimensions (0.180" Dia × 0.345" L). Both substitute parts use the same size code, confirming identical physical form factor.
