Frequently Asked Questions (FAQ)

Q: Can the KEMET T494A225K010AT directly replace the TE Connectivity 2-1879062-1?

A: Yes. The T494A225K010AT provides direct electrical and mechanical equivalence with identical 2.2 µF capacitance, 10 V rating, ±10% tolerance, 6 Ohm ESR, and 1206 package. Both components operate across -55°C to 125°C. The KEMET part is active with ROHS3 compliance, making it suitable for direct substitution.

Q: What is the difference between direct equivalents and upgrade parts?

A: Direct equivalents match all electrical and mechanical specifications of the original part, including voltage rating. Upgrade parts maintain identical capacitance, tolerance, and package but feature higher voltage ratings (16 V, 20 V, or 25 V) or improved tolerance specifications (±5%). Upgrades are electrically compatible and provide enhanced performance margins but are not required for direct replacement.

Q: Are all substitute parts RoHS compliant?

A: All recommended substitute parts are ROHS3 compliant except the KEMET T491A225K016AH, which is RoHS non-compliant. Applications subject to RoHS regulations should exclude this part and select from ROHS3-compliant alternatives.

Q: What is the significance of ESR differences between parts?

A: ESR (Equivalent Series Resistance) values of 6 Ohm, 6.3 Ohm, and 5.9 Ohm are within acceptable variance for this component category. Lower ESR values (5.9 Ohm) provide marginally improved high-frequency performance. Selection based on ESR alone is not required unless the application has specific impedance constraints.

Q: Can I use a 16 V or 25 V rated capacitor in place of the 10 V original?

A: Yes. Higher voltage-rated capacitors are electrically compatible with 10 V applications. The elevated voltage rating provides additional design margin and does not degrade performance. However, physical dimensions and ESR characteristics remain consistent across voltage variants within the same capacitance and package class.

Q: What is the difference between the Vishay Sprague 293D225X9016A2TE3 and 293D225X5016A2TE3?

A: Both parts are 2.2 µF, 16 V, 1206 package capacitors with 5.9 Ohm ESR. The primary difference is tolerance: the 293D225X9016A2TE3 has ±10% tolerance (matching the original specification), while the 293D225X5016A2TE3 has tighter ±5% tolerance. The ±5% variant is suitable for applications requiring improved capacitance accuracy.

Q: Is the Vishay Sprague TH3A225K020C5900 suitable for automotive applications?

A: Yes. The TH3A225K020C5900 carries AEC-Q200 automotive qualification and operates across an extended temperature range of -55°C to 150°C. This part is suitable for automotive and high-reliability applications requiring enhanced temperature performance.

Q: What packaging options are available for these substitute parts?

A: Substitute parts are available in Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging formats. Selection between packaging options depends on procurement and assembly requirements. All parts maintain identical electrical and mechanical specifications regardless of packaging format.

Q: Are all substitute parts available in equivalent inventory quantities?

A: Inventory availability varies by part number and supplier. The KEMET T494A225K010AT offers the highest inventory (6328 Pcs), while the Vishay Sprague TH3A225K020C5900 offers lower availability (986 Pcs). Procurement planning should account for inventory levels and lead times specific to selected alternatives.
