UCY2C680MHD3TO Equivalent & Substitute Parts

Part Overview

The UCY2C680MHD3TO is a 68 µF, 160 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is rated for 12000 hours at 105°C and is designed for general-purpose applications requiring through-hole mounting. The part is Active in product status and fully compliant with ROHS3 and REACH regulations.

Substitute parts are identified when equivalent capacitance and tolerance values are maintained while other electrical parameters may be upgraded to meet higher voltage or performance requirements in circuit designs.

Substitute Part Grouping Explanation

Substitution eligibility for the UCY2C680MHD3TO is determined by the following criteria:

• Capacitance value must remain 68 µF
• Tolerance must remain ±20%
• Voltage rating may be equal to or greater than 160 V
• Polarization must remain Polar
• Mounting type must remain Through Hole
• Package configuration must remain Radial, Can
• Physical dimensions (lead spacing, diameter, height) must remain identical
• Operating temperature range must remain -40°C ~ 105°C
• Lifetime rating must remain 12000 Hrs @ 105°C

The UCY2D680MHD3TO qualifies as a substitute because it maintains all core electrical and mechanical parameters while providing an upgraded voltage rating of 200 V, making it suitable for applications requiring higher voltage tolerance.

Parameter Comparison

Engineering Selection Recommendations

Both the UCY2C680MHD3TO and UCY2D680MHD3TO are Active products with full ROHS3 compliance and REACH compliance status. The primary distinction is the voltage rating: the main part is rated at 160 V, while the substitute is rated at 200 V.

Selection between these parts depends on the circuit voltage requirements. The UCY2D680MHD3TO provides additional voltage margin and is electrically compatible with any application designed for the UCY2C680MHD3TO. Both parts share identical physical dimensions, lead spacing, and thermal characteristics, ensuring direct board-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can the UCY2D680MHD3TO replace the UCY2C680MHD3TO in my circuit?

A: Yes. The substitute part maintains the same capacitance (68 µF), tolerance (±20%), operating temperature range (-40°C ~ 105°C), lifetime rating (12000 Hrs @ 105°C), and physical dimensions. The 200 V rating of the substitute is compatible with any application designed for 160 V operation.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts have identical lead spacing (0.197" / 5.00mm), diameter (0.492" / 12.50mm), and maximum seated height (0.846" / 21.50mm). They are direct mechanical substitutes for through-hole PCB mounting.

Q: What is the difference in ripple current handling?

A: The UCY2D680MHD3TO provides higher ripple current ratings: 650 mA @ 120 Hz and 1.3 A @ 100 kHz, compared to 590 mA @ 120 Hz and 1.18 A @ 100 kHz for the UCY2C680MHD3TO. This represents improved performance in the substitute part.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the UCY2C680MHD3TO and UCY2D680MHD3TO are ROHS3 Compliant and REACH Affected, meeting current environmental and regulatory requirements.

Q: Can I use the UCY2C680MHD3TO in place of the UCY2D680MHD3TO?

A: No. The UCY2C680MHD3TO has a lower voltage rating (160 V) and should not be used in applications requiring 200 V operation. Substitution is unidirectional: upgrade only.
