Substitute Part Grouping Explanation

Substitute parts for the T322F686K025AS are identified based on strict electrical and mechanical parameter matching. The substitution logic requires that all of the following parameters remain identical:

• Capacitance Value: 68 µF (no deviation permitted)
• Voltage Rating: 25 V (no reduction permitted)
• Tolerance: ±10% (must match specification)
• ESR: 800 mOhm (must match specification)
• Dielectric Type: Molded Tantalum (technology-specific)
• Mounting Configuration: Through Hole Axial (PCB compatibility requirement)
• Physical Dimensions: 0.300" Dia x 0.710" L (space constraint requirement)
• Operating Temperature Range: -55°C to 125°C (environmental requirement)

The T322F686K025AT qualifies as a direct substitute because it maintains all critical electrical parameters and physical specifications. The primary distinction between the main part and its substitute relates to compliance certifications and manufacturing batch coding, not functional or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both T322F686K025AS and T322F686K025AT are functionally equivalent for circuit design purposes, with all electrical and mechanical parameters matching exactly. The selection between these parts should be based on compliance requirements:

T322F686K025AS is suitable for applications where RoHS non-compliance is acceptable or where legacy component specifications are required. This part maintains full compatibility with existing designs and procurement specifications.

T322F686K025AT is the appropriate choice for applications requiring ROHS3 compliance. This variant meets modern regulatory requirements while maintaining identical electrical performance and physical form factor. The ROHS3 compliance status makes this part suitable for new designs and applications subject to environmental regulations.

Both parts are manufactured by KEMET, carry Active product status, and are available in production quantities. The choice between them depends solely on the compliance framework of the target application, not on electrical or mechanical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can T322F686K025AT be used as a direct replacement for T322F686K025AS in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The T322F686K025AT can be substituted without circuit redesign or PCB modification. The only difference is RoHS compliance status.

Q: What does the difference in RoHS status mean for component selection?

A: RoHS3 compliance (T322F686K025AT) indicates the part meets current environmental regulations restricting hazardous substances. RoHS non-compliant status (T322F686K025AS) means the part may contain restricted substances. Selection depends on whether the application or end market requires RoHS compliance.

Q: Are the physical dimensions identical between these two parts?

A: Yes. Both parts measure 0.300" diameter by 0.710" length (7.62mm x 18.03mm). They are identical in form factor and will occupy the same PCB footprint.

Q: Do these parts have the same electrical specifications?

A: Yes. Capacitance (68 µF), voltage rating (25 V), tolerance (±10%), ESR (800 mOhm), and operating temperature range (-55°C to 125°C) are identical across both parts.

Q: Which part should be specified for new designs?

A: For new designs, T322F686K025AT is the appropriate choice due to ROHS3 compliance alignment with current manufacturing standards and regulatory requirements.

Q: Can inventory of T322F686K025AS be used interchangeably with T322F686K025AT in production?

A: Yes, from an electrical and mechanical standpoint. However, compliance documentation and traceability records should reflect which variant is used in each production batch.
