UHV1C331MPD Equivalent & Substitute Parts

Part Overview

The UHV1C331MPD is a 330 µF, 16 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 6000 hours at 105°C and is classified as Not For New Designs. Due to its obsolescence status, equivalent and substitute parts from active product lines or higher-rated alternatives are necessary for ongoing production and maintenance applications requiring 330 µF capacitance at 16 V or higher voltage ratings.

Substitute Part Grouping Explanation

Substitution for the UHV1C331MPD is determined by the following criteria:

Primary Substitution Parameters:

Capacitance: 330 µF (exact match required)
Voltage Rating: 16 V minimum (higher ratings acceptable for drop-in replacement)
Tolerance: ±20% (standard for aluminum electrolytic capacitors)
Package: Radial, Can with identical lead spacing (0.138" / 4.60mm)
Physical Dimensions: Case diameter 0.315" (8.00mm) and height 0.512" (13.00mm) maximum
Mounting: Through Hole configuration
Polarization: Polar

Substitution Categories:

Direct Equivalents (Same Voltage): Parts rated at 16 V with identical or superior lifetime ratings and electrical characteristics.
Voltage Upgrades (Higher Voltage): Parts rated at 25 V with 330 µF capacitance. These provide enhanced voltage margin and are mechanically and electrically compatible for applications operating at 16 V or below.
Lifetime Variants: Parts with different thermal lifetime ratings (3000, 6000, 7000, 8000, 9000 hours @ 105°C) but matching voltage and capacitance specifications.

All substitute parts maintain ROHS3 compliance and identical through-hole mounting configuration.

Engineering Selection Recommendations

For Direct 16 V Replacement:

UHE1C331MPD (Nichicon): Provides extended lifetime (7000 Hrs vs. 6000 Hrs) at identical voltage rating. Maintains Not For New Designs status but offers improved thermal endurance.
337KBM016M (Cornell Dubilier): Active product status with 7000-hour lifetime rating. Recommended for new designs requiring 16 V operation with long-term reliability.

For Voltage-Upgraded Replacement (25 V):

25ZLJ330M8X11.5 (Rubycon): Active product with highest lifetime rating (9000 Hrs @ 105°C) and lowest impedance (75 mOhms) among 25 V options. Provides maximum ripple current capacity (660 mA @ 120 Hz).
EEU-FR1E331 (Panasonic): Active product with 6000-hour lifetime and low impedance (56 mOhms). Offers high ripple current capability (665 mA @ 120 Hz).
25ZLH330MEFC8X11.5 (Rubycon): Active product with 8000-hour lifetime and excellent impedance characteristics (56 mOhms).

For Nichicon Series Continuity:

UHV1E331MPD (Nichicon): Same UHV series at 25 V rating. Maintains manufacturer consistency while providing voltage margin.

All recommended active-status parts maintain ROHS3 compliance and identical mechanical compatibility with the original UHV1C331MPD footprint.

Frequently Asked Questions (FAQ)

Q: Can I use a 25 V rated capacitor in place of a 16 V capacitor? A: Yes. A 25 V rated capacitor is a direct drop-in replacement for a 16 V application. The higher voltage rating provides additional safety margin and does not affect circuit operation at lower voltages. All physical dimensions and lead spacing remain identical.

Q: What is the difference between the Nichicon UHV, UHD, and UHE series? A: These series differ primarily in thermal lifetime ratings at 105°C: UHD (3000 Hrs), UHV (6000 Hrs), and UHE (7000 Hrs). All maintain identical capacitance, voltage, and physical package specifications. Selection depends on application lifetime requirements.

Q: Why do some substitute parts have higher impedance values? A: Impedance varies by manufacturer design and internal construction. Lower impedance generally indicates better high-frequency ripple current performance. For applications with high ripple current demands, select parts with impedance ≤ 75 mOhms.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the original UHV1C331MPD environmental certification.

Q: What is the significance of "Active" vs. "Not For New Designs" product status? A: Active products are currently manufactured and recommended for new circuit designs. "Not For New Designs" indicates obsolescence or phase-out status. For new applications, prioritize Active-status parts: 25ZLJ330M8X11.5, 25ZLH330MEFC8X11.5, 25ZLS330MEFC8X11.5, 25YXJ330M8X11.5, 337KBM016M, and EEU-FR1E331.

Q: Can I substitute between different manufacturers? A: Yes. All listed parts maintain identical electrical specifications (330 µF, ±20% tolerance) and mechanical compatibility (radial can package, 4.60mm lead spacing, 8.00mm diameter, 13.00mm height). Cross-manufacturer substitution is electrically and mechanically valid.

Q: Which substitute offers the best ripple current performance? A: 25ZLJ330M8X11.5 (Rubycon) provides the highest ripple current capacity at 660 mA @ 120 Hz and 1.2 A @ 100 kHz, combined with the lowest impedance (75 mOhms) among 25 V options.
