Key Parameters

Substitute Part Grouping Explanation

Substitution for the UHE1C331MPD1TD is determined by the following critical parameters:

Core Electrical Parameters:

• Capacitance: 330 µF (exact match required)
• Tolerance: ±20% (standard tolerance maintained)
• Operating Temperature: -40°C ~ 105°C (full range compatibility)
• Polarization: Polar (electrolytic type)

Mechanical Compatibility:

• Package Type: Radial, Can (through-hole configuration)
• Size / Dimension: 0.315" Dia (8.00mm)
• Height - Seated (Max): 0.512" (13.00mm)
• Mounting Type: Through Hole

Voltage Rating Consideration: Substitute parts with higher voltage ratings (25 V) are acceptable as they provide enhanced safety margin and are backward-compatible in circuits designed for 16 V operation.

Lead Spacing Variation: Two lead spacing options exist among substitutes: 0.138" (4.60mm) and 0.197" (5.00mm). Selection depends on PCB layout compatibility.

Compliance: All substitute parts maintain ROHS3 compliance and EAR99 classification.

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalent: The 860040374005 (Würth Elektronik WCAP-ATUL series) is a direct parametric equivalent to the UHE1C331MPD1TD. Both components share identical electrical specifications: 330 µF capacitance, 16 V voltage rating, ±20% tolerance, 7000-hour lifetime at 105°C, and matching mechanical dimensions. This part maintains active product status and ROHS3 compliance, making it suitable for direct replacement in existing designs.

Upgraded Alternatives with Higher Voltage Rating: The Rubycon YXJ and ZLH series parts (25YXJ330MT78X11.5, 25ZLH330MEFCT78X11.5, 25ZLH330MEFCTA8X11.5) offer 25 V voltage ratings, providing enhanced operational margin in circuits originally designed for 16 V. These upgrades are electrically compatible and backward-compatible. The ZLH series additionally provides extended lifetime (8000 hours at 105°C) and improved electrical performance characteristics (lower impedance, higher ripple current capability).

Lead Spacing Consideration: The 25ZLH330MEFCTA8X11.5 features 0.197" (5.00mm) lead spacing, differing from the standard 0.138" (4.60mm) spacing of the original part. This variant requires PCB layout verification before selection.

Packaging and Availability: All substitute parts are available in active production status with confirmed inventory. Selection between Cut Tape (CT) and Tape & Box (TB) packaging depends on procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can I use a 25 V rated capacitor in place of the 16 V original part? A: Yes. A higher voltage rating provides additional safety margin and is electrically backward-compatible. The circuit will operate normally with no functional degradation. Voltage rating indicates the maximum safe operating voltage; using a higher-rated component in a lower-voltage application is standard engineering practice.

Q: What is the difference between the Rubycon YXJ and ZLH series substitutes? A: Both maintain 330 µF capacitance and 25 V rating. The ZLH series offers improved performance: extended lifetime (8000 hours vs. 7000 hours at 105°C), lower impedance (56 mOhms vs. 130 mOhms), and higher ripple current capability (519.75 mA @ 120 Hz vs. 448 mA). The YXJ series provides a direct electrical match with identical ripple current and impedance specifications.

Q: Does lead spacing affect substitution compatibility? A: Lead spacing affects PCB layout compatibility only. The 25ZLH330MEFCTA8X11.5 uses 0.197" (5.00mm) spacing versus the standard 0.138" (4.60mm). Verify PCB hole spacing before selecting this variant. Other substitutes maintain the original 0.138" (4.60mm) spacing and require no layout modification.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and EAR99 classification, matching the regulatory status of the original UHE1C331MPD1TD.

Q: Why is the original Nichicon part marked "Not For New Designs"? A: This designation indicates the part has reached end-of-life status in the manufacturer's product portfolio. Existing inventory remains available for legacy system support and repair. For new designs, active-status alternatives such as the Würth Elektronik 860040374005 or Rubycon ZLH series are recommended.

Q: What is the significance of impedance differences among substitutes? A: Impedance affects high-frequency performance and ripple current handling. Lower impedance (56 mOhms in ZLH series) indicates better performance at higher frequencies and under ripple current stress. For general-purpose applications at standard operating frequencies, impedance differences are not critical. High-frequency or high-ripple-current applications benefit from lower impedance options.
