Substitute Part Grouping Explanation

Substitution of the UHE1E331MPD6TD is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters for Direct Substitution:

Capacitance: 330 µF (exact match required)
Voltage Rating: 25 V minimum (equal or higher voltage rating is acceptable)
Tolerance: ±20% (standard tolerance match)
Lead Spacing: 0.197" (5.00 mm) (mechanical fit requirement)
Package Diameter: 0.394" (10.00 mm) (PCB footprint requirement)
Package Height: 0.551" (14.00 mm) (clearance requirement)
Mounting Type: Through Hole (assembly method match)
Polarization: Polar (electrical characteristic match)

Substitute parts are categorized into two groups:

Upgrade Substitutes: Parts with identical capacitance and tolerance but higher voltage rating (35 V) and improved lifetime specifications (10000 Hrs @ 105°C). These provide enhanced reliability and are suitable for direct replacement in applications where the original 25 V rating is sufficient.

Parametric Equivalents: Parts with identical electrical specifications (330 µF, 25 V, ±20%, 7000 Hrs @ 105°C) from alternative manufacturers. These maintain full compatibility with the original design parameters.

Engineering Selection Recommendations

For Active Production and New Designs: Select from parts with Active product status: 35YXJ330MT810X12.5, 35ZLH330MEFCT810X12.5, 35ZLH330MT810X12.5, 860160475020, 860040475006, or EKY-250ETD331MJC5S. These components have confirmed ongoing availability and manufacturer support.

For Voltage Margin Enhancement: The Rubycon 35 V rated parts (35YXJ330MT810X12.5, 35ZLH330MEFCT810X12.5, 35ZLH330MT810X12.5) provide 40% additional voltage headroom over the original 25 V specification and extended lifetime (10000 Hrs @ 105°C versus 7000 Hrs). These are suitable direct replacements where circuit design permits higher voltage rating.

For Exact Specification Match: The Würth Elektronik 860160475020 and 860040475006, along with Chemi-Con EKY-250ETD331MJC5S, maintain identical electrical specifications (330 µF, 25 V, 7000 Hrs @ 105°C) with Active product status and full ROHS3 compliance.

For Legacy System Maintenance: The Rubycon 25YXH330MEFCT810X12.5 (Last Time Buy status) and 25YXF330MEFCT810X12.5 (Not For New Designs status) provide parametric equivalence but have limited availability. Prioritize Active status alternatives for long-term supply assurance.

Compliance Considerations: All listed substitute parts are ROHS3 compliant and carry EAR99 ECCN classification, matching the original component's regulatory status.

Frequently Asked Questions (FAQ)

Q: Can I use a 35 V rated capacitor in place of the 25 V UHE1E331MPD6TD? A: Yes. A higher voltage rating (35 V) is electrically compatible with a 25 V application. The capacitor will operate safely at voltages up to its rated maximum. The Rubycon 35 V parts (35YXJ330MT810X12.5, 35ZLH330MEFCT810X12.5, 35ZLH330MT810X12.5) are direct mechanical and electrical substitutes with improved lifetime specifications.

Q: What is the difference between the Rubycon YXJ and ZLH series? A: Both series are 330 µF, 35 V rated with 10000 Hrs @ 105°C lifetime. The primary difference is packaging: YXJ series is available in Tape & Box (TB), while ZLH series is available in both Cut Tape (CT) and Tape & Box (TB) configurations. Electrical performance is equivalent.

Q: Are there packaging differences between substitute parts? A: Yes. Substitute parts are available in Cut Tape (CT) or Tape & Box (TB) packaging. All maintain identical through-hole lead spacing (0.197" / 5.00 mm), package diameter (0.394" / 10.00 mm), and height (0.551" / 14.00 mm), ensuring PCB compatibility regardless of packaging format.

Q: Why is the UHE1E331MPD6TD marked "Not For New Designs"? A: This designation indicates the component has reached end-of-life status at the manufacturer. New designs should utilize Active status alternatives such as 860160475020, 860040475006, EKY-250ETD331MJC5S, or the Rubycon 35 V series for assured long-term availability.

Q: Do all substitute parts have the same ripple current rating? A: No. Ripple current specifications vary by manufacturer and series. The Rubycon ZLH series (35ZLH330MEFCT810X12.5, 35ZLH330MT810X12.5) provides higher ripple current capacity (1.33 A @ 100 kHz) compared to the original UHE series (865 mA @ 100 kHz). Lower ripple current specifications are also available in alternative manufacturers' products. Verify ripple current requirements for your specific application.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the original UHE1E331MPD6TD component.
