UPZ2D121MND9 Equivalent & Substitute Parts

Part Overview

The UPZ2D121MND9 is a 120 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 operating temperature. Substitute parts are identified when equivalent electrical specifications (capacitance, voltage rating, tolerance, and polarization) are maintained while offering improved performance characteristics or alternative mechanical configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the UPZ2D121MND9 are qualified based on the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance: 120 µF (exact match required)
• Voltage Rating: 200 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole
• Package / Case: Radial, Can
• Lead Spacing: Acceptable variations within standard PCB design tolerances
• Physical Dimensions: Acceptable variations provided component fits within allocated board space

Compliance Criteria:

• RoHS Status: ROHS3 Compliant
• Product Status: Active
• REACH Status: REACH Affected

The substitute parts UCY2D121MHD and UCY2D121MHD6 meet all electrical equivalence criteria and maintain through-hole radial can packaging. These substitutes offer extended lifetime ratings (12000 hours at 105°C versus 2000 hours) and improved ripple current handling capabilities.

Parameter Comparison

Engineering Selection Recommendations

UPZ2D121MND9 (Primary Part): Select this part when the original design specification calls for the UPZ series with 2000-hour lifetime rating at 105°C and the specific mechanical envelope of 10.00mm diameter with 42.00mm height is required. This part maintains Active product status and ROHS3 compliance.

UCY2D121MHD6 (Recommended Substitute): This substitute maintains identical lead spacing (0.197" / 5.00mm) and similar height profile (1.299" / 33.00mm) compared to the primary part, reducing PCB layout modifications. The UCY2D121MHD6 offers extended lifetime (12000 hours at 105°C), expanded operating temperature range (-40°C to 105°C), and improved ripple current ratings. All compliance certifications (ROHS3, REACH Affected) are maintained. This part is suitable for direct substitution when enhanced reliability and thermal performance are acceptable.

UCY2D121MHD (Alternative Substitute): This substitute provides the same electrical specifications and extended lifetime (12000 hours at 105°C) but requires PCB layout evaluation due to increased lead spacing (0.295" / 7.50mm) and larger physical dimensions (16.00mm diameter, 21.50mm height). Selection of this part is appropriate when board space permits the larger footprint and the extended thermal performance is required.

Frequently Asked Questions (FAQ)

Q: Can UCY2D121MHD6 be used as a direct replacement for UPZ2D121MND9?

A: Yes. Both parts share identical electrical specifications (120 µF, 200 V, ±20% tolerance, polar configuration) and maintain the same lead spacing (5.00mm). The UCY2D121MHD6 fits within the same PCB footprint with minimal height variation (33.00mm versus 42.00mm). No circuit modifications are required.

Q: What is the primary difference between UCY2D121MHD and UCY2D121MHD6?

A: Both parts are electrically equivalent with identical capacitance, voltage, and tolerance specifications. The primary differences are mechanical: UCY2D121MHD has 7.50mm lead spacing and 16.00mm diameter, while UCY2D121MHD6 has 5.00mm lead spacing and 12.50mm diameter. UCY2D121MHD6 is more compatible with the original UPZ2D121MND9 footprint.

Q: Are there temperature range differences between the main part and substitutes?

A: Yes. The UPZ2D121MND9 operates from -25°C to 105°C, while both UCY substitutes operate from -40°C to 105°C. The extended lower temperature range of the UCY series provides additional operational margin in cold environments.

Q: Do all parts meet RoHS and REACH compliance requirements?

A: Yes. The UPZ2D121MND9 and both UCY substitute parts are ROHS3 Compliant and REACH Affected, maintaining equivalent regulatory compliance status.

Q: What is the lifetime advantage of the substitute parts?

A: The UPZ2D121MND9 is rated for 2000 hours at 105°C, while UCY2D121MHD and UCY2D121MHD6 are rated for 12000 hours at 105°C. This represents a six-fold increase in rated lifetime under identical thermal conditions.

Q: Can UCY2D121MHD be used if board space is limited?

A: No. The UCY2D121MHD has a larger physical envelope (16.00mm diameter, 21.50mm height) and different lead spacing (7.50mm) compared to the original UPZ2D121MND9. PCB layout modifications would be required. UCY2D121MHD6 is the preferred substitute for space-constrained applications.
