Substitute Part Grouping Explanation

Substitution for the T496C105M050AS is determined by strict equivalence in the following parameters:

• Capacitance Value: 1 µF (exact match required)
• Voltage Rating: 50 V (exact match required)
• Package / Case: 2312 (6032 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Type: Molded Tantalum (exact match required)
• Features: Fail Safe with Built-in Fuse (exact match required)

Substitute parts are classified into two categories:

Direct Manufacturer Equivalent: Parts with identical electrical and mechanical specifications, differing only in packaging format or product status.

Parametric Equivalent: Parts meeting all core electrical and mechanical requirements but with variations in tolerance specifications, which remain within acceptable operational parameters for the application.

Parameter Comparison

Engineering Selection Recommendations

T496C105M050AT is the primary direct manufacturer equivalent. This part maintains identical electrical and mechanical specifications to the T496C105M050AS while offering active product status and ROHS3 compliance. The transition from obsolete to active status ensures long-term availability and supply chain continuity. ESR specification of 5.5 Ohm is provided for this substitute.

T496C105K050ATE5K5 serves as a parametric equivalent with tighter tolerance specification (±10% versus ±20%). This part is suitable for applications requiring improved capacitance accuracy while maintaining all other electrical and mechanical characteristics. Active product status and ROHS3 compliance are confirmed for this substitute.

Both substitute parts are available in Tape & Reel packaging format, which differs from the main part's unspecified packaging but represents standard commercial distribution for surface mount components.

Frequently Asked Questions (FAQ)

Q: Can T496C105M050AT be used as a direct replacement for T496C105M050AS?

A: Yes. T496C105M050AT is a direct manufacturer equivalent with identical capacitance (1 µF), voltage rating (50 V), tolerance (±20%), package (2312), and all mechanical dimensions. The primary difference is product status (active versus obsolete) and improved compliance certifications.

Q: What is the difference between T496C105M050AT and T496C105K050ATE5K5?

A: The primary difference is tolerance specification. T496C105M050AT maintains ±20% tolerance matching the original part, while T496C105K050ATE5K5 provides ±10% tolerance. Both parts are electrically and mechanically equivalent in all other parameters. Selection depends on application tolerance requirements.

Q: Are the substitute parts compatible with existing PCB designs for T496C105M050AS?

A: Yes. Both substitute parts use identical 2312 (6032 Metric) packaging with matching dimensions (0.236" L x 0.126" W, 2.80mm maximum height). PCB footprints and assembly processes require no modification.

Q: What is the significance of the ESR specification in the substitute parts?

A: ESR (Equivalent Series Resistance) of 5.5 Ohm is specified for both substitute parts. This parameter was not provided for the original part. ESR affects high-frequency performance and ripple current handling. The specified value is consistent with KEMET T496 series molded tantalum capacitor characteristics.

Q: Are there RoHS compliance differences between the main part and substitutes?

A: Yes. The T496C105M050AS is RoHS non-compliant, while both T496C105M050AT and T496C105K050ATE5K5 are ROHS3 compliant. This represents an improvement in environmental and regulatory compliance for new designs or procurement.

Q: What packaging formats are available for the substitute parts?

A: Both substitute parts are supplied in Tape & Reel (TR) format, which is standard for surface mount component distribution and automated assembly processes.
