Engineering Selection Recommendations

All listed Panasonic substitutes are active products with ROHS3 compliance, providing regulatory advantage over the obsolete Nichicon UPB2V680MHD. Selection between substitute options depends on physical space constraints and lifetime requirements:

For direct footprint replacement with identical dimensions (0.709" diameter, approximately 26-27 mm height): EEU-EB2V680S provides the closest match to the original UPB2V680MHD with 5000-hour lifetime rating and active product status.

For extended lifetime applications: EEU-ED2V680S and EEU-EE2V680S offer 10000-hour ratings at 105°C, doubling the operational life of the original part while maintaining compatible lead spacing and similar physical dimensions.

For space-constrained designs: EEU-ED2V680S provides the most compact height (0.984" / 25.00 mm) among all substitutes while maintaining 10000-hour lifetime and active product status.

All substitute parts share identical electrical specifications (68 µF, 350 V, ±20% tolerance) and lead spacing (0.295" / 7.50 mm), ensuring direct functional compatibility in through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can EEU-EB2V680S directly replace UPB2V680MHD without circuit modification?

A: Yes. Both parts share identical capacitance (68 µF), voltage rating (350 V), tolerance (±20%), lead spacing (0.295" / 7.50 mm), and operating temperature range (-25°C to 105°C). Physical dimensions are compatible with the original design.

Q: What is the difference between EEU-EB2V680S and EEU-ED2V680S?

A: The primary difference is lifetime rating. EEU-EB2V680S is rated for 5000 hours at 105°C, matching the original UPB2V680MHD. EEU-ED2V680S is rated for 10000 hours at 105°C, providing extended operational life. Both maintain identical electrical specifications and lead spacing.

Q: Are there physical dimension differences between substitute options?

A: Yes. Substitute parts vary in diameter and height. EEU-EB2V680S and EEU-EE2V680S with "S" designation match the original 0.709" (18.00 mm) diameter. Non-"S" variants (EEU-EB2V680, EEU-ED2V680, EEU-EE2V680) use 0.630" (16.00 mm) diameter. Height varies from 0.984" to 1.319" depending on series. Verify PCB layout compatibility before selection.

Q: Do all substitutes meet current regulatory requirements?

A: All Panasonic substitutes are ROHS3 compliant and carry active product status. The original Nichicon UPB2V680MHD is obsolete. Panasonic substitutes provide regulatory continuity for new designs and field replacements.

Q: Which substitute offers the best balance of compatibility and performance?

A: EEU-EB2V680S provides direct functional and dimensional compatibility with the original part while offering active product status and ROHS3 compliance. For applications requiring extended lifetime, EEU-ED2V680S or EEU-EE2V680S are suitable alternatives with doubled operational ratings.
