Equivalent & Substitute Parts for UCY2C680MPD

Part Overview

The UCY2C680MPD is a 68 µF, 160 V aluminum electrolytic capacitor in radial, can package 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 currently in active production status and is ROHS3 compliant.

Substitute parts may be required due to packaging format availability, inventory constraints, or application-specific lifetime and ripple current requirements. The following alternatives maintain the core electrical specifications while offering variations in packaging, thermal performance, or mechanical dimensions.

Substitute Part Grouping Explanation

Substitution eligibility for the UCY2C680MPD is determined by the following mandatory parameters:

Capacitance: 68 µF (exact match required)
Voltage Rating: 160 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Mounting Type: Through Hole (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required)
Operating Temperature Range: -40°C to 105°C (exact match required)

Variable parameters that may differ between substitutes include packaging format (Bulk vs. Cut Tape), physical dimensions (diameter and height), lifetime rating at 105°C, ripple current specifications, and product status. These variations do not prevent functional substitution provided the mandatory parameters remain unchanged.

Engineering Selection Recommendations

UCY2C680MPD1TD is a direct substitute for UCY2C680MPD. Both parts are from the active UCY series, share identical electrical specifications, and maintain the same physical footprint. The only difference is packaging format: UCY2C680MPD1TD is supplied in Cut Tape format, while UCY2C680MPD is supplied in Bulk. Both are ROHS3 compliant and REACH Affected. Selection between these two depends solely on procurement and assembly requirements.

UVY2C680MHD is a functional substitute with design constraints. This part maintains all mandatory electrical parameters (68 µF, 160 V, ±20%, polar, through-hole, 5.00 mm lead spacing, -40°C to 105°C). However, it differs in the following aspects:

Product Status: Not For New Designs (legacy component)
Lifetime: 2000 hours at 105°C (versus 12000 hours for UCY series)
Ripple Current: Reduced specifications (250 mA @ 120 Hz, 287.5 mA @ 10 kHz)
Physical Dimensions: Larger diameter (12.50 mm vs. 10.00 mm), shorter height (22.00 mm vs. 26.50 mm)
REACH Status: REACH Unaffected

UVY2C680MHD is suitable only for applications where reduced thermal lifetime and ripple current capacity are acceptable, and where the larger physical footprint does not create PCB layout conflicts.

Frequently Asked Questions (FAQ)

Q: Can UCY2C680MPD1TD replace UCY2C680MPD directly on the same PCB?

A: Yes. Both parts have identical electrical specifications, lead spacing (5.00 mm), and physical dimensions (10.00 mm diameter, 26.50 mm height). The only difference is packaging format (Cut Tape vs. Bulk). No PCB redesign is required.

Q: Is UVY2C680MHD suitable for new designs?

A: No. UVY2C680MHD carries a "Not For New Designs" status, indicating it is a legacy component. It should be used only in applications where existing inventory must be consumed or where design constraints prevent use of active alternatives.

Q: What are the key differences between UCY2C680MPD and UVY2C680MHD?

A: While both maintain the same capacitance (68 µF), voltage (160 V), and lead spacing (5.00 mm), they differ in thermal lifetime (12000 hours vs. 2000 hours at 105°C), ripple current capacity, physical dimensions, and product status. UVY2C680MHD is larger in diameter but shorter in height.

Q: Can I use UVY2C680MHD in a high-ripple-current application?

A: No. UVY2C680MHD has significantly lower ripple current ratings (250 mA @ 120 Hz, 287.5 mA @ 10 kHz) compared to UCY2C680MPD (455 mA @ 120 Hz, 910 mA @ 100 kHz). Applications requiring higher ripple current handling must use the UCY series.

Q: Are all three parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant. However, UCY2C680MPD and UCY2C680MPD1TD are REACH Affected, while UVY2C680MHD is REACH Unaffected. Verify REACH compliance requirements for your specific application and region.

Q: Does the physical size difference between UCY and UVY series affect PCB compatibility?

A: Lead spacing remains identical (5.00 mm), so both fit the same through-hole footprint. However, UVY2C680MHD has a larger diameter (12.50 mm vs. 10.00 mm) and shorter height (22.00 mm vs. 26.50 mm). Verify that the larger diameter does not create clearance issues with adjacent components or PCB features.
