Key Parameters

Substitute Part Grouping Explanation

Substitution of the UPH2W820MHD is determined by strict equivalence across the following critical parameters:

• Capacitance value: 82 µF (exact match required)
• Voltage rating: 450 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package type: Radial, Can (exact match required)
• Mounting type: Through Hole (exact match required)
• Physical dimensions: Lead spacing 0.295" (7.50mm), diameter 0.630" (16.00mm), height 1.319" (34.60mm) (exact match required)
• Operating temperature range: -25°C ~ 105°C (exact match required)

The UCP2W820MHD qualifies as a direct substitute based on full alignment with all critical parameters. The primary distinction is an extended lifetime rating of 10000 hours at 105°C compared to the original 2000-hour specification, representing an improvement in component reliability without any compromise to electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The UCP2W820MHD is the direct substitute for the obsolete UPH2W820MHD. Both components are manufactured by Nichicon and maintain identical electrical and mechanical specifications across all critical parameters. The UCP2W820MHD is currently in active production status, ensuring long-term availability and supply chain continuity.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications. The extended lifetime rating of the UCP2W820MHD (10000 hours at 105°C versus 2000 hours) provides enhanced reliability margins without requiring any design modifications or PCB layout changes.

Frequently Asked Questions (FAQ)

Q: Can the UCP2W820MHD be used as a direct replacement for the UPH2W820MHD?

A: Yes. The UCP2W820MHD is a direct substitute. All electrical parameters (capacitance, voltage rating, tolerance, ripple current) and mechanical dimensions (lead spacing, diameter, height) are identical. The component fits the same PCB footprint and mounting configuration without modification.

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

A: The UCP2W820MHD has an extended lifetime rating of 10000 hours at 105°C compared to the UPH2W820MHD's 2000-hour rating. This represents improved component reliability. No other electrical or mechanical parameters differ.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance and REACH unaffected status. Regulatory requirements are satisfied by either component.

Q: Why is the UPH2W820MHD obsolete?

A: The UPH2W820MHD has been discontinued by Nichicon. The UCP2W820MHD is the active production equivalent and should be used for all new designs and component replenishment.

Q: Will the UCP2W820MHD work in existing circuit designs using the UPH2W820MHD?

A: Yes. Identical electrical specifications and physical dimensions ensure full compatibility with existing designs. No circuit modifications are required.
