Substitute Part Grouping Explanation

Substitution eligibility is determined by strict parameter matching across electrical and mechanical specifications. All substitute parts must maintain:

Capacitance: 330 µF (exact match)
Tolerance: ±20% (exact match)
Voltage Rating: 35 V minimum (equal or higher acceptable)
Lead Spacing: 0.197" (5.00 mm) (exact match)
Package Type: Radial, Can (exact match)
Mounting Type: Through Hole (exact match)
Size / Dimension: 0.394" Dia (10.00 mm) (exact match)
Operating Temperature Range: -40°C ~ 105°C (exact match)
Polarization: Polar (exact match)

Substitute parts are categorized as follows:

Direct Substitutes: Parts with identical electrical and mechanical parameters, differing only in series designation or packaging format.

Upgrade Substitutes: Parts with improved lifetime ratings (10000 Hrs @ 105°C vs. 7000 Hrs) while maintaining all other specifications.

Similar Substitutes: Parts with voltage ratings higher than 35 V, maintaining all other parameters but requiring verification of circuit design constraints.

Parametric Equivalents: Parts meeting all core electrical and mechanical requirements with variations in ripple current handling or impedance characteristics.

Engineering Selection Recommendations

For Active Production: Select from parts with Active product status: 35YXJ330MT810X12.5 (Rubycon), EEU-EB1V331 or EEU-EB1V331B (Panasonic), 860040575009 (Würth Elektronik), or EKY-350ETD331MJ16S (Chemi-Con). These parts are supported for new designs and carry ROHS3 compliance certification.

For Extended Lifetime Requirements: The Rubycon 35YXJ330MT810X12.5, Panasonic EEU-EB1V331, and Panasonic EEU-EB1V331B offer 10000 hours lifetime at 105°C, compared to the original 7000 hours. These parts provide improved reliability margins for long-term applications.

For Compact PCB Layouts: The Rubycon 35YXJ330MT810X12.5 features a reduced height of 0.551" (14.00 mm) versus the standard 0.689" (17.50 mm), enabling space-constrained designs while maintaining all electrical specifications.

For Higher Ripple Current Handling: The Würth Elektronik 860040575009 and Chemi-Con EKY-350ETD331MJ16S deliver significantly higher ripple current ratings (1.035 A and 1.21 A at 100 kHz respectively) compared to the original 364 mA, suitable for high-frequency switching applications.

For Voltage Margin: The Panasonic EEU-EB1H331 provides a 50 V rating with identical capacitance and tolerance, offering additional voltage headroom for circuits operating near the 35 V limit. Note the increased height of 0.866" (22.00 mm) requires PCB layout verification.

Avoid for New Designs: Parts marked "Not For New Designs" (UHE1V331MPD1TD, 35YXF330MEFCT810X16) are suitable only for legacy system maintenance or repair applications.

Frequently Asked Questions (FAQ)

Q: Can I use a 50 V rated capacitor (EEU-EB1H331) in place of the 35 V original?

A: Yes. Higher voltage ratings are electrically compatible with lower voltage circuit requirements. However, the EEU-EB1H331 has a maximum height of 0.866" (22.00 mm) compared to the original 0.689" (17.50 mm). Verify PCB clearance before substitution.

Q: What is the difference between EEU-EB1V331 and EEU-EB1V331B?

A: Both parts are electrically and mechanically identical. The primary difference is packaging: EEU-EB1V331 is supplied in Bulk format, while EEU-EB1V331B is supplied in Cut Tape (CT) format. Select based on your procurement and assembly requirements.

Q: Why do some substitutes have higher ripple current ratings?

A: Ripple current capacity depends on internal construction and thermal design. Higher ratings indicate improved ESR characteristics and thermal performance, allowing the capacitor to handle greater AC current without exceeding temperature limits. This is a performance enhancement, not a requirement for substitution.

Q: Is the Rubycon 35YXJ330MT810X12.5 suitable for my application if space is limited?

A: Yes, provided your circuit design does not depend on the original height. The 35YXJ330MT810X12.5 maintains all electrical specifications while reducing height from 0.689" to 0.551" (17.50 mm to 14.00 mm). Verify that the reduced height does not create mechanical interference with adjacent components.

Q: Are all substitute parts RoHS3 compliant?

A: All listed substitute parts carry ROHS3 Compliant certification. The original UPB1V331MPD1TD does not specify RoHS status. If RoHS compliance is required for your application, select from the substitute parts listed.

Q: Can I use parts marked "Not For New Designs" in production?

A: Parts with "Not For New Designs" status are suitable for maintenance, repair, and legacy system support only. For new production designs, select from parts with Active status to ensure long-term supply availability and manufacturer support.
