Engineering Selection Recommendations

UCY2C151MHD3TN (Direct Substitute): This Nichicon part maintains identical electrical and mechanical specifications to the UCS2C151MHD1TN with the exception of an extended lifetime rating of 12000 hours at 105°C compared to 10000 hours. Both parts are ROHS3 compliant and active in production. The UCY series offers improved thermal endurance for applications requiring extended operational life.

EEU-ED2C151 (Similar Substitute): This Panasonic part matches the core electrical specifications (150 µF, 160 V, ±20% tolerance) and maintains compatible lead spacing and mounting type. Physical height differs at 0.984" (25.00mm) versus 0.846" (21.50mm) for the main part. Ripple current ratings are lower at 630 mA @ 120 Hz and 1.4 A @ 100 kHz. Operating temperature minimum is -25°C versus -40°C. Both parts are ROHS3 compliant and active in production. This substitute is suitable for applications where the increased height and reduced ripple current capacity do not present design constraints.

Frequently Asked Questions (FAQ)

Q: Can UCY2C151MHD3TN be used as a direct replacement for UCS2C151MHD1TN?

A: Yes. Both parts share identical capacitance (150 µF), voltage rating (160 V), tolerance (±20%), lead spacing (7.50mm), physical diameter (16.00mm), height (21.50mm), and mounting configuration. The UCY series provides extended lifetime (12000 hours versus 10000 hours at 105°C).

Q: What are the key differences between EEU-ED2C151 and UCS2C151MHD1TN?

A: The Panasonic EEU-ED2C151 differs in three areas: physical height (25.00mm versus 21.50mm), ripple current capacity (630 mA @ 120 Hz and 1.4 A @ 100 kHz versus 945 mA and 1.89 A respectively), and minimum operating temperature (-25°C versus -40°C). Electrical specifications for capacitance, voltage, and tolerance are identical.

Q: Is the EEU-ED2C151 suitable for high-ripple-current applications?

A: The EEU-ED2C151 has lower ripple current ratings than the UCS2C151MHD1TN. Applications requiring ripple currents exceeding 630 mA @ 120 Hz or 1.4 A @ 100 kHz should use the UCS or UCY series parts.

Q: Will the increased height of EEU-ED2C151 affect PCB layout?

A: The EEU-ED2C151 has a maximum seated height of 25.00mm compared to 21.50mm for the UCS2C151MHD1TN. PCB designs must accommodate this 4.60mm height difference. Lead spacing and diameter remain compatible.

Q: Are all three parts RoHS compliant?

A: Yes. UCS2C151MHD1TN, UCY2C151MHD3TN, and EEU-ED2C151 are all ROHS3 compliant.
