UAS2D680MHD Equivalent & Substitute Parts

Part Overview

The UAS2D680MHD is a 68 µF, 200 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is classified as Active and designed for general-purpose applications requiring reliable energy storage and filtering in circuits operating at 200 V. Substitute parts are necessary when the original component becomes unavailable, when design requirements demand extended operational lifetime, or when higher voltage ratings are required for enhanced circuit reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UAS2D680MHD is determined by the following criteria:

Primary Substitution Parameters:

• Capacitance value must equal 68 µF
• Voltage rating must be equal to or greater than 200 V
• Tolerance must be ±20% or tighter
• Lead spacing must be 0.197" (5.00mm)
• Package configuration must be Radial, Can
• Mounting type must be Through Hole
• Operating temperature range must encompass -40°C ~ 105°C

Secondary Considerations:

• Lifetime at 105°C may exceed the original specification
• Ripple current ratings may exceed the original specification
• Physical dimensions (diameter and height) may vary within mechanical compatibility constraints

Three substitute parts meet these criteria: UCY2E680MHD (upgrade option with higher voltage), UCY2D680MPD (same voltage with extended lifetime), and EKXG201ELL680MK20S (alternative manufacturer with same voltage rating).

Parameter Comparison

Engineering Selection Recommendations

UCY2E680MHD is suitable when circuit design permits operation at 250 V and extended operational lifetime is required. This part provides a 6-month operational advantage at 105°C (12000 Hrs vs. 2000 Hrs) and maintains identical lead spacing and capacitance. Physical dimensions are nearly identical, ensuring PCB compatibility. REACH Status is Affected for this part.

UCY2D680MPD is suitable for direct replacement when extended lifetime at the same 200 V rating is required. This part delivers 12000 Hrs operational life at 105°C and maintains identical electrical specifications. Physical diameter is reduced to 0.394" (10.00mm) with increased height to 1.299" (33.00mm), requiring verification of available PCB space. REACH Status is Affected for this part.

EKXG201ELL680MK20S is suitable when alternative manufacturer sourcing is required. This Chemi-Con part maintains identical electrical specifications and lead spacing with 10000 Hrs lifetime at 105°C. Physical dimensions differ (0.492" diameter, 0.787" height), requiring PCB layout verification. REACH Status is Unaffected for this part, matching the original UAS2D680MHD.

All substitute parts maintain ROHS3 compliance and Active product status.

Frequently Asked Questions (FAQ)

Q: Can UCY2E680MHD replace UAS2D680MHD in a 200 V circuit? A: Yes. The UCY2E680MHD is rated for 250 V, which exceeds the 200 V requirement. Higher voltage-rated capacitors operate safely at lower voltages. Verify PCB layout compatibility due to minimal height difference (1.043" vs. 1.063").

Q: What is the primary advantage of UCY2D680MPD over the original part? A: Extended operational lifetime. UCY2D680MPD provides 12000 Hrs at 105°C compared to 2000 Hrs for UAS2D680MHD, representing a six-fold increase in rated service life. Physical dimensions differ; verify PCB space availability before substitution.

Q: Are all substitute parts pin-compatible with the original UAS2D680MHD? A: Yes. All substitute parts maintain 0.197" (5.00mm) lead spacing and radial, through-hole configuration. However, physical can diameter and height vary. Verify PCB layout clearances, particularly for UCY2D680MPD (increased height) and EKXG201ELL680MK20S (reduced height).

Q: Which substitute part has the best REACH compliance status? A: EKXG201ELL680MK20S maintains REACH Unaffected status, matching the original UAS2D680MHD. UCY2E680MHD and UCY2D680MPD both have REACH Affected status.

Q: Can EKXG201ELL680MK20S be used as a direct drop-in replacement? A: Electrical specifications are compatible. However, physical dimensions differ significantly in height (0.787" vs. 1.063"), requiring PCB layout verification. Lead spacing remains identical at 0.197" (5.00mm).

Q: What ripple current specifications should be considered during substitution? A: All substitute parts exceed the original ripple current ratings. UAS2D680MHD specifies 320 mA @ 120 Hz and 512 mA @ 10 kHz. Substitute parts provide higher ripple current capacity, ensuring safe operation in existing circuits.
