Substitute Part Grouping Explanation

Substitution for the UHE1H331MPD1TD is determined by the following criteria:

Direct Equivalents (Same Electrical Specifications): Parts that maintain identical capacitance (330 µF), voltage rating (50 V), tolerance (±20%), and physical form factor (radial, through-hole, 5.00 mm lead spacing, 10.00 mm diameter) are classified as direct equivalents. These parts are mechanically and electrically interchangeable without circuit modification.

Upgrade Substitutes (Higher Voltage Rating): Parts rated at 63 V with the same capacitance, tolerance, and form factor provide enhanced voltage margin while maintaining full backward compatibility. These are suitable for applications where increased voltage headroom is beneficial.

Compatibility Constraints: All substitute parts must maintain the following parameters to ensure compatibility:

Capacitance: 330 µF
Tolerance: ±20%
Lead Spacing: 0.197" (5.00 mm)
Diameter: 0.394" (10.00 mm)
Mounting Type: Through Hole, Radial
Operating Temperature: -40°C ~ 105°C minimum
Polarization: Polar

Engineering Selection Recommendations

For Direct Replacement (Same Specifications): The 860040675010 (Würth Elektronik WCAP-ATUL series) and EEU-FR1H331LB or EEU-FS1H331B (Panasonic FR-A and FS-A series) are direct electrical and mechanical equivalents. All three maintain 50 V rating, 330 µF capacitance, and ±20% tolerance. The Würth and Panasonic parts carry Active product status, ensuring ongoing availability and support. All are ROHS3 compliant.

For Enhanced Performance (Upgrade Path): The UHW1J331MPD1TD (Nichicon UHW series) and 63ZLJ330MT810X25 (Rubycon ZLJ series) provide 63 V rating with extended lifetime (10000 Hrs @ 105°C versus 7000 Hrs). These upgrades are mechanically compatible and offer improved reliability margins. The Rubycon part carries Active status; the Nichicon upgrade is not for new designs.

Height Consideration: The EEU-FS1H331B features a reduced height of 0.866" (22.00 mm) compared to the standard 1.063" (27.00 mm), suitable for space-constrained applications where vertical clearance is limited.

Impedance Profile: The Panasonic EEU-FR1H331LB and EEU-FS1H331B offer the lowest impedance values (22–23 mOhms), beneficial for high-frequency ripple current applications. The Würth 860040675010 provides mid-range impedance (57 mOhms) with active product status.

Frequently Asked Questions (FAQ)

Q: Can I use a 63 V rated capacitor in place of a 50 V rated capacitor? A: Yes. A higher voltage rating provides additional safety margin and is electrically compatible. The 63 V substitutes (UHW1J331MPD1TD and 63ZLJ330MT810X25) are direct mechanical replacements and will function correctly in circuits designed for 50 V operation.

Q: Are all substitute parts mechanically interchangeable? A: All listed substitutes maintain the same lead spacing (5.00 mm), diameter (10.00 mm), and through-hole mounting configuration. Height variations exist: most are 1.063" (27.00 mm), while the EEU-FS1H331B is 0.866" (22.00 mm). Verify PCB clearance before selecting the shorter variant.

Q: What is the difference between Cut Tape (CT) and Tape & Box (TB) packaging? A: Cut Tape packaging is supplied on individual tape strips, suitable for smaller quantities and manual assembly. Tape & Box packaging (63ZLJ330MT810X25) includes boxed quantities, typically for larger production runs. Both formats contain identical components; packaging choice depends on procurement and assembly requirements.

Q: Why do some parts have longer lifetimes (10000 Hrs vs. 7000 Hrs)? A: Lifetime ratings reflect the capacitor's expected operational duration at maximum rated temperature (105°C). Extended lifetime indicates improved internal construction and materials. For legacy system support, longer-lifetime parts provide enhanced reliability over extended service periods.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed parts, including the original UHE1H331MPD1TD, carry ROHS3 compliance certification, ensuring compatibility with environmental and regulatory requirements.

Q: Which substitute offers the best low-impedance performance? A: The Panasonic EEU-FR1H331LB and EEU-FS1H331B both feature 22–23 mOhms impedance, the lowest among all listed parts. These are preferred for applications requiring superior high-frequency ripple current handling.
