Key Parameters

Substitute Part Grouping Explanation

Substitution of the UPJ1C331MPD1TA is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 330 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• Lead Spacing: 0.138" (4.60mm) (exact match required)
• Size / Dimension: 0.315" Dia (8.00mm) (exact match required)

Flexible Parameters (allowing substitution):

• Voltage Rating: Can be equal or higher than 16 V
• Height - Seated (Max): Minor variations acceptable within mechanical constraints
• Lifetime @ Temperature: Equal or greater than 3000 Hrs @ 105°C
• Impedance: Lower values acceptable (improved performance)
• Ripple Current: Equal or greater values acceptable

Substitute parts are grouped into two categories: parametric equivalents (identical electrical specifications) and upgrades (higher voltage rating with same capacitance and form factor).

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalent: UPJ1C331MPD1TD is a direct parametric equivalent to UPJ1C331MPD1TA. Both parts share identical electrical specifications, physical dimensions, and thermal characteristics. This part maintains the same 16 V voltage rating and 3000 Hrs @ 105°C lifetime. Selection of this equivalent is appropriate for direct replacement in existing designs where the original part number is unavailable.

Upgrade Options (Higher Voltage Rating): UPW1E331MPD6TA, ELXZ250EC3331MH15D, and ELXZ250ETC331MH15D are voltage upgrades rated at 25 V while maintaining the same 330 µF capacitance and physical form factor. These parts are suitable for applications where increased voltage margin is beneficial. The Chemi-Con parts (ELXZ250EC3331MH15D and ELXZ250ETC331MH15D) carry Active product status and AEC-Q200 automotive qualification, making them appropriate for new designs and automotive applications. The Nichicon UPW1E331MPD6TA remains classified as Not For New Designs.

Compliance Considerations: All listed parts are ROHS3 compliant and REACH unaffected. The Chemi-Con LXZ series parts (ELXZ250EC3331MH15D and ELXZ250ETC331MH15D) provide additional value through Active product status and AEC-Q200 certification for automotive-grade reliability.

Frequently Asked Questions (FAQ)

Q: Can UPJ1C331MPD1TD be used as a direct replacement for UPJ1C331MPD1TA? A: Yes. UPJ1C331MPD1TD is a parametric equivalent with identical capacitance (330 µF), voltage rating (16 V), tolerance (±20%), physical dimensions, lead spacing, and thermal characteristics. It is a direct replacement.

Q: What is the difference between parametric equivalents and upgrades? A: Parametric equivalents (UPJ1C331MPD1TD) match all electrical and mechanical specifications of the original part. Upgrades (UPW1E331MPD6TA, ELXZ250EC3331MH15D, ELXZ250ETC331MH15D) provide higher voltage ratings (25 V instead of 16 V) while maintaining the same capacitance and form factor, offering increased voltage margin.

Q: Can I use a 25 V rated capacitor in place of a 16 V rated capacitor? A: Yes, provided all other parameters match. A higher voltage rating is acceptable and does not degrade circuit performance. The 25 V parts listed are mechanically and electrically compatible with the original 16 V design.

Q: What is the significance of "Not For New Designs" status? A: This designation indicates the manufacturer has discontinued active development and promotion of the part. While existing inventory remains available, the manufacturer recommends using alternative parts for new designs. The parametric equivalent UPJ1C331MPD1TD and upgrade options provide forward-compatible alternatives.

Q: Are the Chemi-Con parts (ELXZ250EC3331MH15D and ELXZ250ETC331MH15D) suitable for automotive applications? A: Yes. Both Chemi-Con parts carry AEC-Q200 automotive qualification and Active product status, making them appropriate for automotive-grade applications requiring higher reliability standards.

Q: What is the difference between ELXZ250EC3331MH15D and ELXZ250ETC331MH15D? A: Both parts are identical in electrical specifications, physical dimensions, and thermal characteristics. The difference lies in packaging: ELXZ250EC3331MH15D is supplied in Tape & Reel (TR) format. Both are suitable for the same applications.

Q: Will the slightly taller height (0.650" vs 0.630") of upgrade parts affect PCB layout? A: The height difference of 0.020" (0.50mm) is minimal. Verify clearance in your specific PCB layout and enclosure design. In most applications, this variation is within acceptable mechanical tolerances.

Q: Are all listed parts ROHS3 compliant? A: Yes. All parts listed—UPJ1C331MPD1TA, UPJ1C331MPD1TD, UPW1E331MPD6TA, ELXZ250EC3331MH15D, and ELXZ250ETC331MH15D—are ROHS3 compliant.
