UVK2D680MHD1TO Equivalent & Substitute Parts

Part Overview

The UVK2D680MHD1TO is a 68 µF, 200 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is classified as Not For New Designs, indicating it has been superseded in Nichicon's product portfolio. The part delivers 2000 hours of operational life at 85°C and is suitable for general-purpose applications requiring through-hole mounting.

Finding equivalent or substitute parts is necessary due to the product's discontinued status for new designs. Identifying compatible alternatives ensures design continuity and maintains supply chain reliability for existing applications or legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for aluminum electrolytic capacitors is determined by the following parameters:

• Capacitance Value: Must match exactly (68 µF)
• Tolerance: Must match or be tighter (±20%)
• Voltage Rating: Must be equal to or greater than the original (≥200 V)
• Lead Spacing: Must match for PCB compatibility (0.197" / 5.00mm)
• Physical Dimensions: Must fit within the same footprint envelope
• Mounting Type: Must be through-hole configuration
• Package Style: Must be radial, can format

The UCY2E680MHD1TO meets all substitution criteria. It maintains identical capacitance, tolerance, lead spacing, and physical dimensions while offering superior voltage rating (250 V), extended operational lifetime (12000 Hrs @ 105°C), and wider operating temperature range (-40°C ~ 105°C).

Parameter Comparison

Engineering Selection Recommendations

The UCY2E680MHD1TO is a direct substitute for the UVK2D680MHD1TO based on the following engineering criteria:

Product Status: The substitute part carries Active status, ensuring ongoing manufacturer support and availability, whereas the main part is designated Not For New Designs.

Compliance & Certifications: Both parts maintain ROHS3 compliance. The substitute part is REACH Affected, compared to the main part's REACH Unaffected status. Both carry identical ECCN (EAR99) and HTSUS (8532.22.0020) classifications.

Electrical Compatibility: The substitute provides a higher voltage rating (250 V vs. 200 V), which is acceptable for applications designed for 200 V operation. The identical capacitance (68 µF) and tolerance (±20%) ensure functional equivalence in circuit operation.

Physical Compatibility: Lead spacing and radial can package dimensions are identical, enabling direct PCB footprint compatibility. The substitute's seated height (26.50mm) is marginally lower than the original (27.00mm), presenting no clearance concerns.

Thermal & Reliability Performance: The substitute delivers significantly extended operational lifetime (12000 Hrs @ 105°C vs. 2000 Hrs @ 85°C) and supports a wider operating temperature range (-40°C ~ 105°C vs. -40°C ~ 85°C), providing enhanced reliability margins for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can the UCY2E680MHD1TO be used as a direct replacement on existing PCBs designed for the UVK2D680MHD1TO?

A: Yes. Both parts share identical lead spacing (5.00mm), physical diameter (12.50mm), and radial can package configuration. The substitute's seated height (26.50mm) is within acceptable tolerance relative to the original (27.00mm), ensuring PCB compatibility without modification.

Q: What is the significance of the higher voltage rating on the substitute part?

A: The UCY2E680MHD1TO's 250 V rating exceeds the original 200 V specification. In circuit applications, using a capacitor with a higher voltage rating than required is standard practice and does not affect performance. The capacitance value and tolerance remain identical, ensuring equivalent electrical behavior.

Q: How do the ripple current specifications differ between these parts?

A: The UCY2E680MHD1TO supports higher ripple current across both frequency ranges: 615 mA @ 120 Hz (vs. 350 mA) and 1.23 A @ 100 kHz (vs. 560 mA @ 10 kHz). This enhanced capability provides additional design margin for applications with elevated AC current stress.

Q: What does the product status difference mean for procurement?

A: The main part (Not For New Designs) indicates Nichicon has discontinued active development and recommends alternatives for new applications. The substitute (Active) confirms ongoing production, quality assurance, and supply availability, making it the preferred choice for both new designs and legacy system support.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts are ROHS3 compliant. The substitute is REACH Affected, whereas the main part is REACH Unaffected. For applications subject to REACH regulations, this distinction may require verification against specific regulatory requirements. Both parts carry identical ECCN and HTSUS classifications.
