Engineering Selection Recommendations

Direct Equivalent (Same Voltage Rating): UCA2C680MHD1TO and EEU-ED2C680B both maintain the 160 V rating of the original UPB2C680MHD1TO. UCA2C680MHD1TO offers extended lifetime (12000 Hrs vs. 5000 Hrs) within the Nichicon product family. EEU-ED2C680B provides an active product status from Panasonic with 10000 Hrs lifetime and is currently in production.

Voltage Upgrade Options: UCA2D680MHD1TO (200 V), UPT2P680MHD1TO (220 V), UCY2E680MHD1TO (250 V), EEU-ED2D680B (200 V), and 200CFX68MEFC12.5X25 (200 V) all provide higher voltage ratings while maintaining 68 µF capacitance and ±20% tolerance. These upgrades are electrically compatible in circuits designed for 160 V operation.

Product Status Considerations: UCY2E680MHD1TO and UPT2P680MHD1TO carry Active product status, indicating ongoing production and long-term availability. EEU-ED2C680B and EEU-ED2D680B are Active Panasonic components. UCA2C680MHD1TO and UCA2D680MHD1TO are classified as Not For New Designs but remain available.

Height Variation: EEU-ED2C680B has a maximum seated height of 0.866" (22.00 mm), which is shorter than the original 1.043" (26.50 mm). EEU-ED2D680B and 200CFX68MEFC12.5X25 have heights of 1.063" (27.00 mm) and 1.063" (27.00 mm) respectively, which are slightly taller. PCB layout verification is required for height-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated capacitor as a substitute? A: Yes. A capacitor rated for 200 V, 220 V, or 250 V can replace a 160 V rated capacitor in the same circuit. The higher voltage rating provides additional safety margin and does not degrade circuit performance.

Q: What is the difference between direct equivalents and upgrades? A: Direct equivalents maintain the same voltage rating (160 V) as the original UPB2C680MHD1TO. Upgrades provide higher voltage ratings (200 V, 220 V, or 250 V) while maintaining the same capacitance and tolerance. Both are mechanically and electrically compatible.

Q: Does the height difference between parts affect compatibility? A: Height differences must be evaluated against PCB layout constraints. EEU-ED2C680B is 0.866" (22.00 mm) tall, shorter than the original 1.043" (26.50 mm). EEU-ED2D680B and 200CFX68MEFC12.5X25 are slightly taller at 1.063" (27.00 mm). Verify clearance in your specific application.

Q: What does "Not For New Designs" product status mean? A: Parts marked "Not For New Designs" are still available but are in the later stages of their product lifecycle. Nichicon UCA series parts carry this designation. For new designs, Active status parts such as UCY2E680MHD1TO, UPT2P680MHD1TO, EEU-ED2C680B, and EEU-ED2D680B are preferred.

Q: Are all substitute parts RoHS3 compliant? A: All listed substitute parts are RoHS3 compliant. The original UPB2C680MHD1TO does not specify RoHS status in the provided data.

Q: What packaging options are available? A: Substitute parts are available in Cut Tape (CT) and Bulk packaging. UCA2C680MHD1TO, UCA2D680MHD1TO, UCY2E680MHD1TO, UPT2P680MHD1TO, EEU-ED2C680B, and EEU-ED2D680B are supplied in Cut Tape. 200CFX68MEFC12.5X25 is supplied in Bulk.

Q: Which substitute offers the longest operational lifetime? A: UCA2C680MHD1TO, UCA2D680MHD1TO, and UCY2E680MHD1TO all provide 12000 Hrs lifetime at 105°C, compared to 5000 Hrs for the original UPB2C680MHD1TO. EEU-ED2C680B and EEU-ED2D680B provide 10000 Hrs lifetime.
