Substitute Part Grouping Explanation

Substitution of the T496C106M025AS is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Capacitance: 10 µF (exact match required)
• Voltage Rating: 25 V (exact match required)
• Package / Case: 2312 (6032 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Type: Molded Tantalum (exact match required)

Allowable Parameter Variations:

• Tolerance: ±20% or tighter (±10% acceptable as improvement)
• ESR (Equivalent Series Resistance): Specified values acceptable
• Product Status: Active alternatives preferred over obsolete
• RoHS Compliance: ROHS3 Compliant alternatives preferred
• Packaging Format: Tape & Reel (TR) acceptable for bulk applications

The identified substitute parts T496C106M025ATE600 and T496C106K025AT maintain all primary criteria while offering enhanced specifications in tolerance, ESR definition, and compliance certifications.

Engineering Selection Recommendations

T496C106M025ATE600 (Direct Substitute - Recommended Primary Choice)

This part is the direct functional equivalent of the T496C106M025AS. It maintains identical electrical specifications (10 µF, ±20% tolerance, 25 V rating) and mechanical form factor (2312 package, surface mount). The T496C106M025ATE600 offers the following advantages: active product status (versus obsolete), ROHS3 compliance certification, defined ESR specification of 600 mOhm, and documented lifetime rating of 2000 hours at 85°C. This part is suitable for direct replacement in existing designs and new production applications.

T496C106K025AT (Parametric Equivalent - Secondary Choice)

This part provides an alternative with improved tolerance specification (±10% versus ±20%), while maintaining all other critical parameters including capacitance, voltage rating, package, and operating temperature range. The T496C106K025AT also features active product status and ROHS3 compliance. Selection of this part is appropriate when tighter capacitance tolerance is required by circuit design specifications. The ±10% tolerance represents an enhancement over the original ±20% specification.

Compliance and Regulatory Considerations

Both substitute parts achieve ROHS3 compliance, addressing regulatory requirements that may not have been applicable to the original obsolete part. Both parts maintain REACH Unaffected status and EAR99 export classification, consistent with the original component. Moisture sensitivity level remains at MSL 1 (Unlimited) across all three parts, indicating no special moisture handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can T496C106M025ATE600 be used as a direct replacement for T496C106M025AS?

A: Yes. The T496C106M025ATE600 maintains identical electrical specifications (10 µF capacitance, ±20% tolerance, 25 V rating) and mechanical dimensions (2312 package, 6.00mm x 3.20mm x 2.80mm height). Both parts feature fail-safe design with built-in fuse protection and operate across -55°C to 125°C. The substitute part offers improved product status (active versus obsolete) and ROHS3 compliance.

Q: What is the difference between T496C106M025ATE600 and T496C106K025AT?

A: The primary difference is tolerance specification. T496C106M025ATE600 maintains ±20% tolerance matching the original part, while T496C106K025AT offers tighter ±10% tolerance. Both parts share identical capacitance (10 µF), voltage rating (25 V), package (2312), and operating temperature range (-55°C to 125°C). Selection between these parts depends on circuit tolerance requirements.

Q: Are the substitute parts available in different packaging formats?

A: Both substitute parts are available in Tape & Reel (TR) packaging format, suitable for automated assembly processes. The original T496C106M025AS packaging format is not specified in the provided data. Tape & Reel format is standard for high-volume production applications.

Q: Do the substitute parts have specified ESR values?

A: Yes. Both T496C106M025ATE600 and T496C106K025AT specify ESR (Equivalent Series Resistance) at 600 mOhm. The original T496C106M025AS does not include ESR specification. Defined ESR values enable more precise circuit performance prediction, particularly in applications sensitive to impedance characteristics.

Q: Are there any moisture sensitivity or handling differences?

A: No. All three parts maintain identical Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no special moisture handling requirements during storage, transportation, or assembly processes.

Q: What is the inventory status of substitute parts?

A: T496C106M025ATE600 has 1650 pieces in stock. T496C106K025AT has 1909 pieces in stock. Both parts are classified as active products with established supply availability.
