URZ1E331MPD Equivalent & Substitute Parts

Part Overview

The URZ1E331MPD is a 330 µF, 25 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, with a rated lifetime of 1000 hours at 105°C. Due to its obsolete status, equivalent and substitute parts from active or not-for-new-designs product lines are necessary for ongoing production support and design continuity.

Substitute Part Grouping Explanation

Substitution of the URZ1E331MPD is determined by strict equivalence in the following parameters:

Capacitance: 330 µF (exact match required)
Voltage Rating: 25 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)

Substitute parts may vary in the following parameters without affecting functional compatibility:

Lifetime @ 105°C (1000 Hrs, 2000 Hrs, 3000 Hrs, or 5000 Hrs)
Physical dimensions (lead spacing, diameter, height)
Ripple current ratings
Impedance values
Product status (Obsolete, Not For New Designs, or Active)
Series designation (URZ, UPS, UPJ, UPM, UPW, UVY, UVZ, UWT)

All substitute parts listed maintain ROHS3 compliance and operate within the -55°C ~ 105°C temperature range.

Engineering Selection Recommendations

For applications requiring through-hole mounting with 330 µF, 25 V specifications, the following selection criteria apply:

Active Product Status: UPW1E331MPD6 is the only through-hole substitute with active product status, offering 3000 hours lifetime at 105°C with high inventory availability (11988 pcs).

Extended Lifetime Requirements: For applications requiring extended operational life, UPJ1E331MPD6, UPM1E331MPD6, and UPW1E331MPD provide 5000 hours lifetime at 105°C.

Automotive Applications: UPM1E331MPD and UPM1E331MPD6 carry AEC-Q200 ratings and are designated for automotive use.

Surface Mount Alternative: UWT1E331MNL1GS provides an active, surface-mount equivalent with SMD package configuration for PCB assembly applications.

Compliance: All listed substitutes maintain ROHS3 compliance and REACH unaffected or affected status as specified in individual part data.

Frequently Asked Questions (FAQ)

Q: Can URZ1E331MPD be directly replaced with any of the listed substitutes?

A: Yes. All listed through-hole mounted substitutes (UPJ1E331MPD, UPJ1E331MPD6, UPM1E331MPD, UPM1E331MPD6, UPS1E331MPD, UPW1E331MPD, UPW1E331MPD6, UVY1E331MPD, UVZ1E331MPD) share identical electrical specifications: 330 µF capacitance, 25 V voltage rating, ±20% tolerance, and polar radial can package. Physical dimensions may vary; verify lead spacing and height clearance for your PCB layout.

Q: What is the difference between lifetime ratings (1000 Hrs, 2000 Hrs, 3000 Hrs, 5000 Hrs)?

A: Lifetime rating indicates the expected operational duration at 105°C before capacitance degradation reaches 80% of initial value. Higher lifetime ratings provide extended service life under thermal stress. Selection depends on application duty cycle and thermal environment.

Q: Is UWT1E331MNL1GS compatible with through-hole PCB designs?

A: No. UWT1E331MNL1GS is a surface-mount device (SMD) with radial can package. It requires SMD land pattern and reflow soldering. Through-hole designs must use one of the radial through-hole substitutes listed.

Q: Which substitute offers the best inventory availability?

A: UVZ1E331MPD provides the highest inventory stock at 55,519 pcs, followed by UPW1E331MPD6 at 11,988 pcs.

Q: Are automotive-grade substitutes available?

A: Yes. UPM1E331MPD and UPM1E331MPD6 carry AEC-Q200 automotive qualification ratings.
