Substitute Part Grouping Explanation

Substitution of the T496C226M016AS is determined by strict equivalence in the following parameters:

Primary Equivalence Criteria:

• Capacitance value: 22 µF (exact match required)
• Voltage rating: 16 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)

Secondary Compatibility Parameters:

• Operating temperature range: -55°C ~ 125°C (must meet or exceed)
• Features: Fail Safe with Built-in Fuse (maintained across all substitutes)

Allowable Variations:

• Tolerance: ±20% (main part) to ±10% (substitute) — tighter tolerance is acceptable
• ESR (Equivalent Series Resistance): Specified in active substitutes (1.6Ohm) versus unspecified in obsolete main part
• Packaging format: Bulk to Tape & Reel (TR) — format change does not affect electrical compatibility
• Product status: Obsolete to Active — substitutes are current production parts
• RoHS compliance: Non-compliant (main) to ROHS3 Compliant (substitutes)

Parameter Comparison

Engineering Selection Recommendations

T496C226M016AT (Direct Substitute): This part is the direct successor to the T496C226M016AS. It maintains identical electrical specifications (22 µF, ±20% tolerance, 16 V rating) and mechanical compatibility (2312 package, identical dimensions). The primary differences are product status (Active versus Obsolete) and regulatory compliance (ROHS3 Compliant). This part is recommended as the primary replacement for obsolete inventory management and new procurement.

T496C226K016ATE1K6 (Parametric Equivalent): This part provides tighter capacitance tolerance (±10% versus ±20%) while maintaining all other electrical and mechanical parameters. It is suitable for applications requiring improved capacitance accuracy. Like T496C226M016AT, it is an active product with ROHS3 compliance. Selection of this part should be based on application tolerance requirements rather than general substitution needs.

Both substitute parts are manufactured by KEMET in the same T496 series and share identical physical dimensions, thermal characteristics, and fail-safe features with the main part. Packaging format differences (Tape & Reel versus Bulk) do not affect electrical performance and reflect current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can T496C226M016AT be used as a direct replacement for T496C226M016AS?

A: Yes. T496C226M016AT is electrically and mechanically equivalent to T496C226M016AS. Both parts have identical capacitance (22 µF), tolerance (±20%), voltage rating (16 V), package (2312), and operating temperature range (-55°C ~ 125°C). The primary difference is product status; T496C226M016AT is an active production part, while T496C226M016AS is obsolete.

Q: What is the difference between T496C226M016AT and T496C226K016ATE1K6?

A: The primary difference is capacitance tolerance. T496C226M016AT has ±20% tolerance, while T496C226K016ATE1K6 has ±10% tolerance. All other parameters—capacitance value, voltage rating, package, dimensions, and operating temperature—are identical. Selection between these parts depends on application tolerance requirements.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts use the 2312 (6032 Metric) package with identical dimensions: 0.236" L x 0.126" W (6.00mm x 3.20mm) and maximum seated height of 0.110" (2.80mm). They are mechanically interchangeable on PCBs designed for the T496C226M016AS.

Q: What does the packaging format change from Bulk to Tape & Reel mean?

A: Packaging format refers to how components are supplied for assembly. Bulk packaging is typical for older or obsolete parts, while Tape & Reel (TR) is the current standard for automated assembly. This change does not affect the electrical or mechanical properties of the component itself.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both T496C226M016AT and T496C226K016ATE1K6 are ROHS3 Compliant. The original T496C226M016AS is RoHS non-compliant. If RoHS compliance is required for your application, either substitute part is suitable.

Q: What is ESR and why is it specified in the substitutes but not the main part?

A: ESR (Equivalent Series Resistance) is an internal resistance parameter that affects capacitor performance in high-frequency applications. Both substitute parts specify 1.6Ohm ESR at 85°C. The main part does not have this specification documented, but the substitutes provide this additional performance data for design verification.

Q: Can I use T496C226K016ATE1K6 in place of T496C226M016AT?

A: Yes, with the understanding that T496C226K016ATE1K6 has tighter tolerance (±10% versus ±20%). This makes it suitable for any application requiring T496C226M016AT, with the added benefit of improved capacitance accuracy.
