UPH2W101MHD Equivalent & Substitute Parts

Part Overview

The UPH2W101MHD is a 100 µF, 450 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is classified as Active product status and is designed for general purpose applications requiring polar capacitive energy storage. The UPH series operates across a temperature range of -25°C to 105°C with a rated lifetime of 2000 hours at 105°C. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same voltage class, capacitance value, and form factor, while potentially offering enhanced performance characteristics such as extended operational lifetime.

Substitute Part Grouping Explanation

Substitution of the UPH2W101MHD is permissible when the following criteria are satisfied:

Electrical Equivalence Requirements:

• Capacitance value: 100 µF (exact match)
• Voltage rating: 450 V (exact match or higher)
• Tolerance: ±20% (matching or tighter tolerance acceptable)
• Polarization: Polar (must match)

Mechanical Compatibility Requirements:

• Package type: Radial, Can (exact match)
• Mounting type: Through Hole (exact match)
• Physical dimensions: 0.630" Dia (16.00mm) and 1.476" (37.50mm) height (exact match)
• Lead spacing: 0.295" (7.50mm) (exact match)

Compliance Requirements:

• RoHS3 Compliant status maintained
• Operating temperature range: -25°C ~ 105°C (matching or extended range acceptable)

The UCP2W101MHD qualifies as a direct substitute based on identical satisfaction of all electrical, mechanical, and compliance parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

Both the UPH2W101MHD and UCP2W101MHD are Active status products manufactured by Nichicon with full ROHS3 compliance. The components are electrically and mechanically identical across all specified parameters. Selection between these parts should be based on application-specific lifetime requirements and operational conditions. The UCP2W101MHD offers extended operational lifetime (10000 hours at 105°C versus 2000 hours), making it suitable for applications requiring enhanced reliability over extended service periods. Both components satisfy identical compliance and certification requirements.

Frequently Asked Questions (FAQ)

Q: Can the UCP2W101MHD replace the UPH2W101MHD in existing designs?

A: Yes. The UCP2W101MHD is a direct substitute. All electrical parameters (capacitance, voltage rating, tolerance, ripple current specifications), mechanical dimensions (package type, lead spacing, physical size), and compliance certifications are identical. No circuit redesign or PCB modification is required.

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

A: The UCP2W101MHD provides extended operational lifetime (10000 hours at 105°C) compared to the UPH2W101MHD (2000 hours at 105°C). Both parts are otherwise electrically and mechanically equivalent.

Q: Are there any mounting or installation differences?

A: No. Both components use identical Through Hole mounting with 0.295" (7.50mm) lead spacing, 0.630" (16.00mm) diameter, and 1.476" (37.50mm) maximum seated height. PCB footprints and assembly procedures remain unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the UPH2W101MHD and UCP2W101MHD are ROHS3 Compliant with identical REACH and ECCN classifications.

Q: Which part should be selected for new designs?

A: Selection depends on application lifetime requirements. For applications requiring extended operational reliability, the UCP2W101MHD is appropriate. For general purpose applications with shorter service life expectations, either part is suitable based on availability and cost considerations.
