Engineering Selection Recommendations

Direct Equivalent Selection:

The KEMET T494A225M010AT provides the most direct electrical equivalent to the TE Connectivity 2-1879062-2. This part maintains identical capacitance (2.2 µF), voltage rating (10 V), tolerance (±20%), and ESR (6 Ohm) specifications. The T494A225M010AT is classified as Active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment.

The Vishay Sprague 293D225X0010A2TE3 serves as an alternative direct substitute with equivalent electrical performance. The ESR specification of 6.3 Ohm is marginally higher than the original 6 Ohm but remains within acceptable operating parameters for general-purpose tantalum capacitor applications. This part is also Active status with ROHS3 compliance.

Upgrade Selection for Enhanced Performance:

For applications requiring improved voltage margin or tighter tolerance control, the following upgrade options are available:

293D225X0016A2TE3 (Vishay Sprague): 16 V rating with ±20% tolerance and 5.9 Ohm ESR provides 60% voltage headroom increase over the original 10 V specification.
293D225X0020A2TE3 (Vishay Sprague): 20 V rating with ±20% tolerance and 5.9 Ohm ESR provides 100% voltage headroom increase.
293D225X0025A2TE3 (Vishay Sprague): 25 V rating with ±20% tolerance and 6.3 Ohm ESR provides 150% voltage headroom increase.
293D225X5016A2TE3 (Vishay Sprague): 16 V rating with ±5% tolerance and 5.9 Ohm ESR offers tighter capacitance tolerance for precision applications.
TH3A225M020D5900 (Vishay Sprague): 20 V rating with ±20% tolerance, 5.9 Ohm ESR, and AEC-Q200 automotive qualification for applications requiring automotive-grade reliability.
F931E225MAA (KYOCERA AVX): 25 V rating with ±20% tolerance and 6.3 Ohm ESR @ 100kHz with 2000 Hrs @ 125°C lifetime rating.

All substitute parts maintain the 1206 (3216 Metric) package dimensions, surface mount configuration, MSL 1 moisture sensitivity level, and -55°C to 125°C operating temperature range required for direct mechanical and thermal compatibility.

Frequently Asked Questions (FAQ)

Q: Can the KEMET T494A225M010AT be used as a direct replacement for the TE Connectivity 2-1879062-2?

A: Yes. The T494A225M010AT maintains identical electrical specifications: 2.2 µF capacitance, 10 V voltage rating, ±20% tolerance, and 6 Ohm ESR. The 1206 package dimensions and surface mount configuration are identical. This part is classified as Active status with ROHS3 compliance, ensuring availability and regulatory compliance.

Q: What is the difference between direct substitutes and upgrade substitutes?

A: Direct substitutes maintain the original 10 V voltage rating and ±20% tolerance specification. Upgrade substitutes provide higher voltage ratings (16 V, 20 V, or 25 V) or tighter tolerance specifications (±10% or ±5%) while maintaining the same 2.2 µF capacitance and 1206 package. Upgrade parts are suitable for applications requiring improved performance margins.

Q: Are all substitute parts compatible with the original 1206 package footprint?

A: Yes. All listed substitute parts use the 1206 (3216 Metric) package with identical physical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm) and maximum seated height of 0.071" (1.80mm). All parts are surface mount components with identical lead spacing and mounting requirements.

Q: What is the significance of ESR (Equivalent Series Resistance) differences between parts?

A: ESR affects capacitor performance in high-frequency applications and ripple current handling. The original part specifies 6 Ohm ESR. Substitute parts range from 5.9 Ohm to 6.3 Ohm. The 5.9 Ohm variants provide marginally improved high-frequency performance, while 6.3 Ohm variants remain within acceptable operating parameters for general-purpose applications.

Q: Can I use a 25 V rated capacitor in a circuit designed for 10 V?

A: Yes. A 25 V rated capacitor can be used in a 10 V circuit. The voltage rating indicates the maximum voltage the capacitor can withstand. Using a higher-rated capacitor provides additional safety margin and does not negatively affect circuit operation. However, physical space constraints and cost considerations should be evaluated.

Q: What does MSL 1 (Unlimited) moisture sensitivity level mean?

A: MSL 1 indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. All listed substitute parts maintain MSL 1 classification, ensuring compatibility with standard manufacturing and storage procedures.

Q: Are the Vishay Sprague TANTAMOUNT™ series parts equivalent to the original TE Connectivity part?

A: The Vishay Sprague 293D series (TANTAMOUNT™) parts are functionally equivalent or superior to the original TE Connectivity part. The 293D225X0010A2TE3 provides direct electrical equivalence at 10 V with ±20% tolerance. Higher voltage variants in the 293D series provide upgrade options with improved voltage margins.

Q: What is the advantage of the AEC-Q200 rated TH3A225M020D5900?

A: The TH3A225M020D5900 carries AEC-Q200 automotive qualification, indicating compliance with automotive reliability and quality standards. This part is suitable for automotive applications requiring enhanced reliability assurance. The 20 V rating provides 100% voltage headroom over the original 10 V specification.

Q: Do all substitute parts have ROHS3 compliance?

A: All listed substitute parts are ROHS3 compliant. The original TE Connectivity 2-1879062-2 is classified as REACH Unaffected. ROHS3 compliance ensures the substitute parts meet current environmental and regulatory requirements for electronic component manufacturing and use.

Q: Can I mix different manufacturers' parts in the same circuit board?

A: Yes. All listed substitute parts maintain identical electrical specifications, package dimensions, and operating characteristics within their respective categories. Mixing manufacturers (TE Connectivity, Vishay Sprague, KEMET, KYOCERA AVX) in the same circuit board is acceptable from an electrical and mechanical standpoint. However, procurement and quality assurance procedures should account for multiple supplier sources.
