UPH2W151MHD Equivalent & Substitute Parts

Part Overview

The UPH2W151MHD is a 150 µF, 450 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is rated for 2000 hours at 105°C and is designed for general-purpose applications requiring through-hole mounting. The part is currently active in production with ROHS3 compliance and REACH unaffected status. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, application redesign, or supply chain considerations.

Substitute Part Grouping Explanation

Substitution of the UPH2W151MHD is determined by strict equivalence in the following parameters:

• Capacitance: 150 µF (exact match required)
• Voltage Rating: 450 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package Configuration: Radial, Can (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.295" (7.50mm) (exact match required)
• Physical Dimensions: 0.709" Dia × 1.654" Height (exact match required)
• Operating Temperature Range: -25°C ~ 105°C (exact match required)

The UCP2W151MHD qualifies as a direct substitute based on full alignment with these critical parameters. Differences in lifetime rating and ripple current specifications at different frequencies do not affect substitution eligibility when the core electrical and mechanical requirements are identical.

Parameter Comparison

Engineering Selection Recommendations

Both UPH2W151MHD and UCP2W151MHD are active production components from Nichicon with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on application lifetime requirements. The UCP2W151MHD offers extended operational life (10000 hours at 105°C) compared to the UPH2W151MHD (2000 hours at 105°C), making it suitable for applications requiring longer service intervals. Both parts meet identical electrical and mechanical specifications for 150 µF, 450 V radial aluminum electrolytic capacitor applications with through-hole mounting.

Frequently Asked Questions (FAQ)

Q: Can UCP2W151MHD replace UPH2W151MHD in existing designs?

A: Yes. Both parts share identical capacitance, voltage rating, tolerance, physical dimensions, lead spacing, and mounting configuration. Direct substitution is electrically and mechanically compatible.

Q: What is the difference between these two parts?

A: The primary differences are lifetime rating and high-frequency ripple current specification. UCP2W151MHD is rated for 10000 hours at 105°C versus 2000 hours for UPH2W151MHD. The UCP2W151MHD also specifies ripple current at 100 kHz while UPH2W151MHD specifies at 10 kHz. These differences do not affect substitution eligibility for applications with matching electrical requirements.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical RoHS3 compliance and REACH unaffected status.

Q: What mounting considerations apply to both parts?

A: Both parts are through-hole mounted radial capacitors with 0.295" (7.50mm) lead spacing and identical physical dimensions of 0.709" diameter and 1.654" maximum seated height. PCB layout and footprint requirements are identical.

Q: Which part should be selected for long-term reliability applications?

A: Selection should be based on application lifetime requirements. UCP2W151MHD with 10000-hour rating is appropriate for applications requiring extended operational life. UPH2W151MHD with 2000-hour rating is suitable for applications with shorter service intervals.
