Equivalent & Substitute Parts for UPJ2C330MHD1TO

Part Overview

The UPJ2C330MHD1TO is a 33 µF, 160 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is classified as "Not For New Designs," indicating it has been superseded in the product lifecycle. The part is rated for 5000 hours at 105°C and is suitable for general-purpose applications requiring through-hole mounting with 5.00 mm lead spacing.

Substitute Part Grouping Explanation

Substitution of the UPJ2C330MHD1TO is determined by the following criteria:

Parametric Equivalents: Parts with identical capacitance (33 µF), voltage rating (160 V), tolerance (±20%), lead spacing (5.00 mm), and case diameter (12.50 mm). These parts maintain full electrical and mechanical compatibility.

Direct Substitutes: Parts with identical capacitance and voltage rating but improved lifetime specifications or enhanced ripple current ratings. These provide drop-in replacement capability with performance enhancements.

Upgrade Substitutes: Parts with higher voltage ratings (200 V, 250 V, or 400 V) or extended lifetime ratings. These are suitable when circuit design permits higher voltage margins or when extended operational life is required. Physical dimensions remain compatible within the specified lead spacing and case diameter tolerances.

Cross-Manufacturer Alternatives: Parts from alternative manufacturers (Würth Elektronik) meeting the same electrical specifications and mechanical form factor.

Engineering Selection Recommendations

For Direct Replacement (Same Electrical Specifications): UPM2C330MHD1TO provides parametric equivalence with identical electrical and mechanical characteristics. This part is suitable for applications where the original specification must be maintained exactly. Note that UPM2C330MHD1TO carries AEC-Q200 automotive qualification, making it appropriate for automotive-grade applications.

For Performance Enhancement (Extended Lifetime): UPW2C330MHD1TO offers 7000-hour lifetime at 105°C compared to the original 5000 hours, with marginally improved ripple current handling. Physical height is reduced to 22.00 mm, providing potential PCB layout benefits. This part remains in "Not For New Designs" status.

For Voltage Margin Improvement: UPW2D330MHD1TO (200 V) and UPW2E330MHD1TO (250 V) provide higher voltage ratings while maintaining the same capacitance and tolerance. These are suitable when circuit design permits voltage derating for improved reliability margins.

For Maximum Performance and Active Status: UCY2G330MHD1TO is the only active product in the Nichicon lineup, rated at 400 V with 12000-hour lifetime at 105°C. This part provides the highest performance envelope and is recommended for new designs requiring long-term component availability and extended operational life.

For Cross-Manufacturer Sourcing: 860241178003 (Würth Elektronik WCAP-AT1H series) provides an active alternative with 250 V rating and 10000-hour lifetime. Case diameter is 13.00 mm (0.512"), which is within typical PCB tolerance for 12.50 mm footprints but should be verified for specific board layouts. This part offers superior ripple current capability at 375 mA @ 120 Hz.

Frequently Asked Questions (FAQ)

Q: Can UPM2C330MHD1TO be used as a direct replacement for UPJ2C330MHD1TO? A: Yes. UPM2C330MHD1TO is a parametric equivalent with identical capacitance (33 µF), voltage rating (160 V), tolerance (±20%), lifetime (5000 Hrs @ 105°C), and physical dimensions. The primary difference is AEC-Q200 automotive qualification in the UPM series.

Q: What is the advantage of UPW2C330MHD1TO over the original part? A: UPW2C330MHD1TO extends the lifetime to 7000 hours at 105°C and reduces the seated height from 27.00 mm to 22.00 mm, potentially improving PCB layout density. Ripple current ratings are marginally improved.

Q: Can I use UCY2G330MHD1TO (400 V) in place of UPJ2C330MHD1TO (160 V)? A: Yes, from an electrical compatibility standpoint. The 400 V rating provides a 2.5× voltage safety margin over the original 160 V specification. However, verify that the circuit design accommodates the higher voltage rating and that the physical dimensions (26.50 mm height vs. 27.00 mm original) are acceptable for the PCB layout.

Q: Why is UCY2G330MHD1TO recommended for new designs? A: UCY2G330MHD1TO carries "Active" product status, ensuring long-term availability and manufacturing support. It provides the highest performance specifications: 400 V rating, 12000-hour lifetime at 105°C, and superior ripple current handling (385 mA @ 120 Hz, 770 mA @ 100 kHz).

Q: Is the Würth Elektronik part 860241178003 mechanically compatible? A: The part is mechanically compatible for through-hole mounting with 5.00 mm lead spacing. The case diameter is 13.00 mm compared to 12.50 mm for Nichicon parts. Verify PCB pad sizing and clearances for your specific layout, as this 0.50 mm difference may affect tight board designs.

Q: What is the difference between "Not For New Designs" and "Active" product status? A: "Not For New Designs" indicates the manufacturer has discontinued active development and recommends alternatives for new applications. "Active" status confirms ongoing manufacturing, quality support, and long-term availability, making it the preferred choice for designs with extended production lifecycles.

Q: Can I mix different substitute parts in the same circuit? A: All listed substitutes maintain the same capacitance (33 µF) and tolerance (±20%), making them functionally interchangeable from a circuit operation standpoint. However, for consistency in manufacturing and quality control, use a single part number across identical circuit positions.
