Substitute Part Grouping Explanation

Substitution eligibility for the UCS2E820MND9 is determined by the following critical parameters:

• Capacitance Value: Must be 82 µF (no deviation permitted)
• Voltage Rating: Must be 250 V or higher
• Tolerance: Must be ±20% or tighter
• Polarization: Must be Polar
• Mounting Type: Must be Through Hole
• Package Type: Must be Radial, Can
• Lead Spacing: Must be 0.197" (5.00mm)
• Operating Temperature Range: Must support -40°C ~ 105°C minimum
• RoHS Compliance: Must maintain RoHS3 compliance

The UCY2E820MHD meets all substitution criteria. Both parts share identical capacitance, voltage rating, tolerance, polarization, mounting type, package configuration, and lead spacing. Both operate across the required temperature range and maintain RoHS3 compliance. Differences in physical dimensions (diameter and height) and lifetime ratings do not prevent substitution when circuit board layout permits the larger form factor.

Parameter Comparison

Engineering Selection Recommendations

Both UCS2E820MND9 and UCY2E820MHD are active production parts with full RoHS3 compliance and identical electrical ratings. Selection between these parts depends on application-specific constraints:

UCS2E820MND9 is suitable when board space is constrained and the smaller form factor (10.00mm diameter, 42.00mm height) is required. This part delivers the specified 10000-hour lifetime at 105°C.

UCY2E820MHD is suitable when extended component lifetime is beneficial. The larger form factor (12.50mm diameter, 33.00mm height) accommodates higher ripple current ratings (715 mA @ 120 Hz, 1.43 A @ 100 kHz) and provides 12000-hour lifetime at 105°C. This part requires verification that circuit board layout can accommodate the increased diameter.

Both parts are electrically interchangeable when mechanical fit is confirmed. Lead spacing remains constant at 0.197" (5.00mm), ensuring PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can UCY2E820MHD replace UCS2E820MND9 in an existing design?

A: Yes, provided the circuit board layout accommodates the larger diameter (12.50mm vs 10.00mm). All electrical parameters, voltage rating, capacitance value, tolerance, and lead spacing are identical. Physical clearance around the component must be verified.

Q: What is the primary difference between these two parts?

A: The main differences are physical dimensions and lifetime rating. UCY2E820MHD has a larger diameter but shorter height, with a 2000-hour extended lifetime at 105°C (12000 hours vs 10000 hours). Ripple current handling is also higher in the UCY2E820MHD.

Q: Are both parts RoHS3 compliant?

A: Yes, both UCS2E820MND9 and UCY2E820MHD are RoHS3 compliant and suitable for applications requiring environmental compliance.

Q: Does lead spacing differ between these parts?

A: No, both parts maintain 0.197" (5.00mm) lead spacing, ensuring identical PCB footprint compatibility.

Q: Which part should be selected for high-ripple-current applications?

A: UCY2E820MHD is rated for higher ripple currents (715 mA @ 120 Hz and 1.43 A @ 100 kHz) compared to UCS2E820MND9 (610 mA @ 120 Hz and 1.22 A @ 100 kHz). Selection depends on actual circuit ripple current requirements and available board space.
