Key Parameters

Substitute Part Grouping Explanation

Substitution of the UVZ2W100MHD1TO is determined by strict electrical and mechanical compatibility. All substitute parts must meet the following core criteria:

Mandatory Parameters for Direct Substitution:

• Capacitance: 10 µF (exact match)
• Voltage Rating: 450 V minimum
• Tolerance: ±20%
• Polarization: Polar
• Package: Radial, Can
• Lead Spacing: 0.197" (5.00 mm)
• Case Diameter: 0.492" (12.50 mm)
• Mounting Type: Through Hole

Secondary Considerations:

• Height variation within mechanical envelope
• Lifetime rating (higher ratings provide extended service life)
• Ripple current capability (higher values indicate improved performance margin)
• Product status (Active status preferred for new procurement)

The substitute parts listed below satisfy all mandatory parameters and are grouped by their relationship to the original specification.

Parameter Comparison

Engineering Selection Recommendations

Nichicon UCS2W100MHD1TO is the primary recommended substitute. This part maintains Nichicon manufacturing continuity, carries Active product status for ongoing availability, and provides 10000 hours lifetime at 105°C—a five-fold improvement over the original UVZ2W100MHD1TO. Mechanical compatibility is confirmed with height of 0.846" (21.50 mm), which remains within typical PCB layout tolerances.

Nichicon UCY2H100MHD1TO provides an alternative with elevated voltage rating of 500 V, extending operational margin in applications subject to voltage transients. This part is Active status and rated for 10000 hours at 105°C. The higher voltage rating does not compromise physical compatibility.

Rubycon 450BXC10MEFCG412.5X20 offers cross-manufacturer substitution with 12000 hours lifetime at 105°C and Active product status. Physical dimensions match the original specification exactly, including height of 0.866" (22.00 mm).

Panasonic EEU-EB2W100B and EPCOS B43858C5106M8 provide alternative sourcing with Active product status. Both are rated for 5000 hours at 105°C and maintain identical physical envelope to the original part.

Nichicon UCA2W100MHD1TO delivers the highest lifetime rating at 12000 hours but retains Not For New Designs status, limiting its suitability for new procurement despite superior performance characteristics.

Panasonic ECA-2WHG100B matches the original 2000-hour lifetime specification and provides parametric equivalence with Active product status.

All listed substitutes are ROHS3 compliant and suitable for direct PCB replacement without design modification.

Frequently Asked Questions (FAQ)

Q: Can UCY2H100MHD1TO replace UVZ2W100MHD1TO in a 450 V circuit?

A: Yes. The UCY2H100MHD1TO is rated for 500 V, which exceeds the 450 V requirement. Higher voltage rating provides additional safety margin and does not degrade performance in lower-voltage applications. All other electrical and mechanical parameters are compatible.

Q: What is the significance of "Not For New Designs" status?

A: This designation indicates the manufacturer has discontinued active development and recommends alternative parts for new product designs. However, the part remains functionally valid for repair and maintenance of existing systems. Active-status alternatives such as UCS2W100MHD1TO are preferred for new procurement.

Q: Are there height differences between substitute parts?

A: Yes. The original UVZ2W100MHD1TO has a maximum seated height of 0.866" (22.00 mm). Nichicon UCS2W100MHD1TO and UCY2H100MHD1TO are slightly shorter at 0.846" (21.50 mm). This 0.020" (0.50 mm) reduction is within standard PCB layout tolerances and does not require design modification. Rubycon, Panasonic, and EPCOS alternatives maintain the original 0.866" (22.00 mm) height.

Q: How do lifetime ratings affect component selection?

A: Lifetime rating indicates hours of operation at maximum rated temperature (105°C) before capacitance degradation reaches specified limits. Higher ratings provide extended service life. The original 2000-hour rating can be upgraded to 5000, 10000, or 12000 hours using listed substitutes, improving system reliability without design changes.

Q: Is packaging format interchangeable between substitutes?

A: All listed substitutes use Cut Tape (CT) or Tape & Box (TB) packaging, which are standard for through-hole radial capacitors. Physical lead spacing of 0.197" (5.00 mm) and case diameter of 0.492" (12.50 mm) are identical across all parts, ensuring direct PCB compatibility.

Q: Can I use a substitute with higher ripple current rating?

A: Yes. Ripple current capability indicates the maximum AC current the capacitor can safely handle. Higher ratings provide additional performance margin. All listed substitutes meet or exceed the original specification and are suitable for direct replacement.
