UPZ2D151MND9 Equivalent & Substitute Parts

Part Overview

The UPZ2D151MND9 is a 150 µF, 200 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as Active product status and is designed for general purpose applications requiring through-hole mounting. The UPZ series offers a rated lifetime of 2000 hours at 105°C with an operating temperature range of -25°C to 105°C.

Equivalent and substitute parts become necessary when the original component reaches end-of-life status, inventory constraints occur, or when design requirements call for enhanced performance characteristics such as extended lifetime ratings or improved ripple current handling at higher frequencies.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UPZ2D151MND9 is determined by the following mandatory parameters:

• Capacitance: 150 µF (exact match required)
• Voltage Rating: 200 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)

All substitute parts listed maintain these core electrical and mechanical specifications. Variations in physical dimensions, lifetime ratings, ripple current capabilities, and operating temperature ranges are permitted within the scope of substitution, provided the mandatory parameters remain unchanged.

The substitute parts are grouped into two categories: Nichicon series alternatives (UCY and URZ) and cross-manufacturer alternatives (Chemi-Con KXG series).

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain ROHS3 compliance and are classified as Active product status. Selection among substitute parts should be based on the following criteria derived from provided specifications:

For applications requiring extended operational lifetime: The UCY series (UCY2D151MHD, UCY2D151MHD3, UCY2D151MHD6) offers 12000 hours at 105°C, compared to the original UPZ2D151MND9 rating of 2000 hours. The EKXG201ELL151ML25S (Chemi-Con) provides 10000 hours at 105°C as an intermediate option.

For applications with expanded temperature requirements: The UCY series and EKXG201ELL151ML25S extend the lower operating temperature limit to -40°C, compared to the UPZ series lower limit of -25°C.

For applications requiring higher ripple current handling: The UCY2D151MHD and EKXG201ELL151ML25S deliver superior ripple current performance at high frequencies (1.93 A and 1.89 A at 100 kHz respectively), versus the original part's 1.162 A at 10 kHz.

For space-constrained designs: The UCY2D151MHD6 provides the most compact height at 0.846 inches (21.50mm) while maintaining 12000-hour lifetime rating.

For cost-sensitive applications with reduced lifetime requirements: The URZ2D151MHD offers a lower-cost alternative with 1000-hour lifetime rating, though with reduced ripple current capacity.

Frequently Asked Questions (FAQ)

Q: Can I use UCY2D151MHD3 as a direct replacement for UPZ2D151MND9 on a PCB designed for the original part?

A: Electrical substitution is valid. However, physical dimensions differ: the UCY2D151MHD3 has a larger diameter (0.630" vs 0.394") and different lead spacing (0.295" vs 0.197"). PCB layout verification is required to confirm mechanical fit within the available footprint space.

Q: What is the difference between UCY2D151MHD and UCY2D151MHD3?

A: Both parts share identical electrical specifications (150 µF, 200 V, ±20%, 12000 Hrs @ 105°C). The primary differences are physical dimensions and lead spacing. UCY2D151MHD uses 0.197" lead spacing with 0.492" diameter, while UCY2D151MHD3 uses 0.295" lead spacing with 0.630" diameter. Selection depends on available PCB space and mounting hole configuration.

Q: Is the EKXG201ELL151ML25S (Chemi-Con) fully compatible with Nichicon parts?

A: Yes, for electrical and functional purposes. All mandatory parameters (capacitance, voltage, tolerance, polarization, package type, mounting type) are identical. The Chemi-Con part offers 10000-hour lifetime at 105°C and maintains ROHS3 compliance. Cross-manufacturer substitution is valid when electrical specifications match.

Q: Why does URZ2D151MHD have lower ripple current ratings than other substitutes?

A: The URZ2D151MHD is rated for 1000 hours at 105°C, indicating a different internal design optimized for cost rather than high-frequency ripple current performance. This part is suitable only for applications where ripple current demands are moderate and extended lifetime is not required.

Q: Can I substitute UPZ2D151MND9 with a part having different voltage rating?

A: No. Voltage rating is a mandatory substitution parameter. The 200 V rating must be maintained. Using a lower voltage-rated capacitor creates reliability and safety risks. Using a higher voltage-rated capacitor is not a valid substitution as it changes the component specification.
