Nichicon UCS2D820MND9 Equivalent & Substitute Parts

Part Overview

The Nichicon UCS2D820MND9 is an 82 µF, 200 V aluminum electrolytic capacitor in radial, can package configuration rated for 10,000 hours at 105°C. This part is classified as obsolete. Due to its obsolete status, equivalent substitute parts from Nichicon's active product lines are necessary for new designs and ongoing production requirements. Substitute parts maintain the same electrical specifications while offering improved availability and extended product lifecycle support.

Substitute Part Grouping Explanation

Substitution of the UCS2D820MND9 is determined by the following critical parameters:

Electrical Equivalence: Capacitance (82 µF), voltage rating (200 V), and tolerance (±20%) must match exactly
Package Compatibility: Radial, can package with through-hole mounting required
Mechanical Fit: Lead spacing and physical dimensions must accommodate the original PCB layout
Thermal Performance: Operating temperature range must support -40°C to 105°C minimum
Compliance: RoHS3 compliance and REACH status for regulatory requirements

Substitute parts are grouped by mechanical dimensions (lead spacing and case size) since these determine PCB compatibility. All substitute parts maintain identical electrical specifications while offering active product status and improved lifecycle support.

Engineering Selection Recommendations

Direct Mechanical Replacement (Same Lead Spacing and Case Size):

UPZ2D820MND9 provides the closest mechanical fit with identical lead spacing (0.138", 4.60mm) and case diameter (0.315", 8.00mm). This part is active and RoHS3 compliant. Note that the operating temperature minimum is -25°C versus -40°C on the original part, and lifetime is reduced to 2,000 hours at 105°C.

Alternative Mechanical Configurations:

For applications where PCB layout permits different lead spacing and case dimensions, the following active alternatives are available:

UCY2D820MHD and UCY2D820MHD3 (UCY series): Offer extended lifetime of 12,000 hours at 105°C with full -40°C to 105°C operating range and RoHS3 compliance. Mechanical dimensions differ from the original part.
UAQ2D820MHD and UAQ2D820MHD6 (UAQ series): Provide 2,000-hour lifetime at 105°C with -40°C to 105°C operating range and RoHS3 compliance. Mechanical dimensions differ from the original part.
UAS2D820MHD (UAS series): Offers 2,000-hour lifetime at 105°C with -40°C to 105°C operating range and RoHS3 compliance. Mechanical dimensions differ from the original part.

All substitute parts maintain the same electrical specifications (82 µF, 200 V, ±20% tolerance) and are suitable for general-purpose applications. Selection should be based on PCB layout constraints and thermal lifetime requirements.

Frequently Asked Questions (FAQ)

Q: Can UPZ2D820MND9 be used as a direct replacement for UCS2D820MND9?

A: UPZ2D820MND9 provides identical mechanical fit with matching lead spacing (4.60mm) and case diameter (8.00mm). However, the operating temperature minimum is -25°C instead of -40°C, and thermal lifetime is 2,000 hours versus 10,000 hours at 105°C. Verify application requirements before substitution.

Q: What is the difference between the UCY and UAQ series substitutes?

A: UCY2D820MHD and UCY2D820MHD3 offer extended thermal lifetime of 12,000 hours at 105°C. UAQ2D820MHD and UAQ2D820MHD6 provide 2,000-hour lifetime. Both series support the full -40°C to 105°C operating range. Selection depends on thermal performance requirements and available PCB space.

Q: Are all substitute parts RoHS3 compliant?

A: All substitute parts listed are RoHS3 compliant. The original UCS2D820MND9 is REACH Unaffected. Most substitutes are REACH Affected (UCY2D820MHD and UCY2D820MHD3) or REACH Unaffected (UAQ2D820MHD6, UAQ2D820MHD, UAS2D820MHD). Verify REACH compliance requirements for your application.

Q: Can I use a substitute with different lead spacing on my existing PCB?

A: No. Lead spacing determines PCB hole pattern compatibility. Substitutes with different lead spacing (5.00mm or 7.50mm) require PCB redesign. For direct PCB compatibility without layout changes, use UPZ2D820MND9, which maintains the original 4.60mm lead spacing.

Q: Which substitute offers the longest thermal lifetime?

A: UCY2D820MHD and UCY2D820MHD3 provide 12,000-hour lifetime at 105°C, compared to 2,000 hours for UAQ and UAS series alternatives. These parts are suitable for applications requiring extended thermal performance.
