URU2C330MHD1TO Equivalent & Substitute Parts

Part Overview

The URU2C330MHD1TO is a 33 µF, 160 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 2000 hours at 85°C and is designed for general-purpose applications requiring through-hole mounting. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs requiring compatible specifications.

Substitute Part Grouping Explanation

Substitution for the URU2C330MHD1TO is determined by the following critical parameters:

Capacitance Value: Must be 33 µF (±20% tolerance acceptable)
Voltage Rating: Minimum 160 V (equal or higher voltage ratings are acceptable)
Package Type: Radial, can configuration with through-hole mounting
Lead Spacing: 5.00 mm or compatible spacing for PCB layout
Polarization: Polar (aluminum electrolytic)
Operating Temperature: Must support the application's thermal requirements

Two substitute parts are identified:

URY2C330MHD1TO (Direct Equivalent): Same capacitance, voltage, and package with improved temperature rating (105°C vs. 85°C) and extended lifetime at elevated temperature (2000 Hrs @ 105°C).
URZ2D330MHD1TN (Similar Substitute): Same capacitance and tolerance with higher voltage rating (200 V vs. 160 V), larger physical dimensions, and different lead spacing (7.50 mm vs. 5.00 mm). This part is active and currently available.

Engineering Selection Recommendations

URY2C330MHD1TO is the preferred direct equivalent for applications requiring drop-in replacement. This part maintains identical capacitance, voltage rating, and physical dimensions while offering superior thermal performance (105°C operating temperature vs. 85°C) and extended lifetime at elevated temperature. ROHS3 compliance provides regulatory advantage for new designs. Packaging in cut tape format supports automated assembly processes.

URZ2D330MHD1TN is suitable for applications where PCB layout can accommodate larger physical dimensions and different lead spacing (7.50 mm vs. 5.00 mm). The higher voltage rating (200 V) provides additional design margin but requires verification of PCB footprint compatibility. This part is currently active and available in inventory. ROHS3 compliance is confirmed.

Selection between URY2C330MHD1TO and URZ2D330MHD1TN depends on PCB layout constraints and lead spacing requirements. Both parts are Nichicon products with confirmed REACH compliance and EAR99 classification.

Frequently Asked Questions (FAQ)

Q: Can URY2C330MHD1TO directly replace URU2C330MHD1TO without PCB modification?

A: Yes. Both parts share identical capacitance (33 µF), voltage rating (160 V), lead spacing (5.00 mm), and physical dimensions (0.492" diameter, 0.551" height). No PCB layout changes are required.

Q: What is the impact of the different lead spacing in URZ2D330MHD1TN?

A: URZ2D330MHD1TN has 7.50 mm lead spacing compared to 5.00 mm in the main part. This requires PCB footprint modification and cannot be used as a direct drop-in replacement without layout redesign.

Q: Does the higher voltage rating of URZ2D330MHD1TN affect circuit performance?

A: No. A 200 V rated capacitor operates correctly in a 160 V circuit. The higher voltage rating provides additional safety margin and does not alter electrical performance at the specified operating voltage.

Q: Are there compliance differences between the substitute parts?

A: URY2C330MHD1TO and URZ2D330MHD1TN are both ROHS3 compliant and REACH unaffected. Both carry EAR99 classification. The main part does not specify RoHS status.

Q: What is the significance of the different lifetime ratings?

A: URY2C330MHD1TO provides 2000 hours at 105°C, matching the main part's 2000-hour rating at 85°C. URZ2D330MHD1TN provides 1000 hours at 105°C, which is lower. For applications requiring extended operational life at elevated temperatures, URY2C330MHD1TO is preferred.

Q: Can these parts be used interchangeably in all applications?

A: URY2C330MHD1TO is fully interchangeable with URU2C330MHD1TO. URZ2D330MHD1TN requires PCB layout verification due to different lead spacing and physical dimensions before implementation.
