UPB2C680MHD Equivalent & Substitute Parts

Part Overview

The UPB2C680MHD is a 68 µF, 160 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, with 805 units currently in stock. The UPB series is rated for 5000 hours at 105°C and is designed for general-purpose applications requiring through-hole mounting with 5.00 mm lead spacing.

Due to its obsolete status, identifying equivalent and substitute parts is essential for design continuity, production planning, and long-term component availability. Substitute parts are selected based on matching or exceeding the electrical and mechanical parameters of the original specification.

Substitute Part Grouping Explanation

Substitute parts for the UPB2C680MHD are categorized based on the following substitution criteria:

Upgrade Substitutes — Parts with equal or higher voltage ratings, equal or longer lifetime ratings, and identical mechanical dimensions. These parts provide enhanced performance characteristics while maintaining full form-factor compatibility.

Similar Substitutes — Parts with matching capacitance and tolerance but differing in one or more secondary parameters such as case diameter, lifetime, or operating temperature range. These require verification of mechanical fit and thermal performance requirements.

Direct Substitutes — Parts from alternative manufacturers with equivalent electrical specifications and identical mechanical form factors, suitable for direct replacement in existing designs.

The primary parameters determining substitution eligibility are:

Capacitance: 68 µF (fixed)
Tolerance: ±20% (fixed)
Lead Spacing: 5.00 mm (fixed)
Mounting Type: Through Hole (fixed)
Voltage Rating: 160 V minimum
Lifetime: 5000 Hrs minimum @ 105°C
Case Diameter: 12.50 mm (preferred)
Height: 26.50 mm (preferred)

Engineering Selection Recommendations

Primary Recommendation: UCY2E680MHD (Nichicon)

The UCY2E680MHD is the preferred substitute for the UPB2C680MHD. This part maintains identical mechanical dimensions (12.50 mm diameter, 26.50 mm height, 5.00 mm lead spacing) and capacitance specification (68 µF ±20%). The UCY2E680MHD offers superior electrical performance with a 250 V rating (exceeding the 160 V requirement) and extended lifetime of 12000 hours at 105°C. The part is currently in active production status with 1542 units in stock. RoHS3 compliance is confirmed.

Secondary Recommendation: UPT2P680MHD or UPT2P680MHD1TO (Nichicon)

Both variants of the UPT series provide active-status alternatives with identical mechanical compatibility. The 220 V rating exceeds the original 160 V specification. These parts maintain the 5000-hour lifetime rating of the original UPB2C680MHD. UPT2P680MHD1TO is available in Cut Tape packaging with 1749 units in stock, while UPT2P680MHD is available in Bulk packaging with 926 units. Both are RoHS3 compliant.

Alternative Recommendation: 200BXC68MEFC12.5X25 (Rubycon)

This Rubycon BXC series part provides a 200 V rating with 12000-hour lifetime. Mechanical dimensions are nearly identical (12.50 mm diameter, 27.00 mm height versus 26.50 mm original). Lead spacing matches at 5.00 mm. RoHS3 compliance is confirmed with 1149 units available.

Cross-Manufacturer Option: EEU-ED2C680 (Panasonic)

The Panasonic EEU-ED2C680 matches the original 160 V rating and maintains identical lead spacing and case diameter. Height is reduced to 20.00 mm, which may be advantageous in space-constrained designs. Lifetime is rated at 10000 hours at 105°C. RoHS3 compliance is confirmed with 1223 units in stock.

Not Recommended: UCY2C680MPD (Nichicon)

While this part offers matching voltage and extended lifetime, the case diameter is reduced to 10.00 mm, creating a mechanical incompatibility with the original 12.50 mm specification. This part should only be considered if PCB layout modifications are acceptable.

Frequently Asked Questions (FAQ)

Q: Can I use UCY2E680MHD as a direct replacement for UPB2C680MHD?

A: Yes. The UCY2E680MHD maintains identical mechanical dimensions and lead spacing. The higher voltage rating (250 V versus 160 V) and extended lifetime (12000 hours versus 5000 hours) provide enhanced performance margins. No circuit modifications are required.

Q: What is the difference between UPT2P680MHD and UPT2P680MHD1TO?

A: Both parts are electrically and mechanically identical. The primary difference is packaging: UPT2P680MHD is supplied in Bulk packaging, while UPT2P680MHD1TO is supplied in Cut Tape (CT) format. Selection depends on assembly process requirements and inventory management preferences.

Q: Why is the EEU-ED2C680 shorter than the original part?

A: The EEU-ED2C680 has a seated height of 20.00 mm compared to the original 26.50 mm. This is a design characteristic of the Panasonic ED-A series. Verify that the reduced height is compatible with your PCB layout and component clearance requirements before substitution.

Q: Can I use parts with higher voltage ratings as substitutes?

A: Yes. A capacitor with a higher voltage rating than the original specification can be used as a substitute, provided all other parameters (capacitance, tolerance, lead spacing, mounting type) match or exceed requirements. Higher voltage ratings provide additional safety margin and do not negatively impact circuit performance.

Q: What does "Active" product status mean?

A: Active status indicates the part is currently in production and available for new orders. Obsolete status indicates the part is no longer manufactured. For long-term design continuity, active-status substitutes are preferred.

Q: Are all listed substitutes RoHS3 compliant?

A: All substitute parts listed are confirmed RoHS3 compliant. The original UPB2C680MHD does not have RoHS status specified in the provided data.

Q: Can I substitute a Rubycon part for a Nichicon part?

A: Yes, provided electrical and mechanical specifications match. The 200BXC68MEFC12.5X25 and 250BXC68MEFC12.5X25 from Rubycon are suitable substitutes. Verify that your design does not include manufacturer-specific requirements or qualifications before substitution.

Q: What is the significance of the ripple current ratings?

A: Ripple current ratings indicate the maximum AC current the capacitor can handle at specified frequencies (120 Hz for low-frequency applications, 100 kHz for high-frequency applications). Ensure the substitute part's ripple current rating meets or exceeds your circuit's requirements.
