Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the T491C106M016AT4513 are identified based on strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 10 µF
• Voltage - Rated: 16 V
• Package / Case: 2312 (6032 Metric)
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C ~ 125°C
• Lifetime @ Temp.: 2000 Hrs @ 125°C
• Type: Molded Tantalum

Allowable Variation Parameters:

• Tolerance: ±20% (original) to ±10% (substitute acceptable as tighter tolerance)
• ESR (Equivalent Series Resistance): 1.8 Ohm (original) to 2 Ohm (substitute acceptable within general purpose application range)
• Manufacturer: KEMET or Cal-Chip Electronics, Inc.

Substitutes are grouped into two categories: direct KEMET series equivalents and cross-manufacturer alternatives from Cal-Chip Electronics, Inc. All identified substitutes maintain identical physical dimensions, electrical ratings, and environmental compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

T491C106M016AT7280 (KEMET): This substitute maintains identical electrical specifications and ESR characteristics to the primary part. Both components are manufactured by KEMET within the same T491 series, ensuring design continuity and performance equivalence. Selection of this part is appropriate when KEMET product line continuity is required and inventory availability of the original part number is constrained.

TCMIC106CT (Cal-Chip Electronics, Inc.): This substitute provides equivalent capacitance, voltage rating, and package specifications with a tolerance of ±20%, matching the original part. The ESR specification of 2 Ohm represents a minor increase from 1.8 Ohm but remains within acceptable parameters for general purpose tantalum capacitor applications. This part is suitable for applications where cross-manufacturer sourcing is acceptable and Cal-Chip inventory availability is advantageous.

TCKIC106CT (Cal-Chip Electronics, Inc.): This substitute offers a tighter tolerance specification of ±10% compared to the original ±20% tolerance, providing enhanced capacitance accuracy. The ESR specification of 2 Ohm is consistent with other Cal-Chip alternatives. This part is appropriate for applications requiring improved capacitance tolerance performance while maintaining all other electrical and mechanical compatibility parameters.

All substitute parts maintain ROHS3 compliance, MSL Level 1 (Unlimited) moisture sensitivity rating, and REACH Unaffected status, ensuring regulatory and environmental compliance equivalence with the original component.

Frequently Asked Questions (FAQ)

Q: Can T491C106M016AT7280 be used as a direct replacement for T491C106M016AT4513?

A: Yes. Both parts are manufactured by KEMET within the T491 series and share identical electrical specifications including 10 µF capacitance, 16 V rating, 1.8 Ohm ESR, and 2312 (6032 Metric) package dimensions. The parts differ only in manufacturing batch coding (AT4513 versus AT7280), which does not affect functional performance or compatibility.

Q: What is the difference between KEMET and Cal-Chip substitute options?

A: KEMET substitutes (T491C106M016AT7280) maintain identical ESR of 1.8 Ohm. Cal-Chip substitutes (TCMIC106CT and TCKIC106CT) feature ESR of 2 Ohm, which is within acceptable parameters for general purpose applications. Cal-Chip parts offer higher inventory availability. Both manufacturers provide ROHS3 compliance and equivalent environmental ratings.

Q: Is the ESR difference between 1.8 Ohm and 2 Ohm significant?

A: The 0.2 Ohm difference represents approximately 11% variation and is within the normal performance envelope for general purpose molded tantalum capacitors. This variation does not affect circuit functionality in standard applications. Applications with specific ESR requirements should confirm compatibility with circuit design parameters.

Q: Can TCKIC106CT with ±10% tolerance replace TCMIC106CT with ±20% tolerance?

A: Yes. TCKIC106CT provides tighter tolerance control, making it suitable for any application accepting TCMIC106CT. The ±10% tolerance is a subset of ±20% tolerance performance, ensuring enhanced capacitance accuracy without compromising compatibility.

Q: Are all substitute parts identical in physical dimensions?

A: Yes. All substitute parts conform to the 2312 (6032 Metric) package specification with dimensions of 0.236" L x 0.126" W (6.00mm x 3.20mm) and maximum seated height of 0.110" (2.80mm). Physical interchangeability is confirmed for all identified substitutes.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts maintain ROHS3 compliance, MSL Level 1 (Unlimited) moisture sensitivity rating, and REACH Unaffected status. These certifications ensure regulatory equivalence with the original T491C106M016AT4513 component across industrial and commercial applications.

Q: Are there inventory considerations when selecting substitutes?

A: Yes. T491C106M016AT4513 has 889 Pcs in stock. T491C106M016AT7280 has 4,080 Pcs available. TCMIC106CT has 62,064 Pcs available. TCKIC106CT has 62,019 Pcs available. Substitute selection may be influenced by required delivery timelines and inventory availability.
