Substitute Part Grouping Explanation

Substitution of the UVZ1E331MPD is determined by the following critical parameters:

Primary Matching Criteria:

Capacitance: 330 µF (exact match required)
Voltage Rating: 25 V minimum (equal or higher voltage rating acceptable)
Tolerance: ±20% (standard tolerance maintained)
Polarization: Polar (electrolytic type maintained)
Mounting Type: Through Hole (PCB compatibility)
Package Type: Radial, Can (form factor compatibility)

Secondary Compatibility Factors:

Lead Spacing: 0.197" (5.00 mm) preferred for direct PCB fit
Case Diameter: 0.394" (10.00 mm) preferred for mechanical clearance
Height: 0.492" (12.50 mm) or less preferred for space constraints
Operating Temperature: -55°C to 105°C (standard range maintained)

Substitute parts are grouped into two categories:

Upgrade Substitutes – Higher voltage rating (35 V) with same capacitance, providing improved voltage margin while maintaining electrical compatibility.
Similar Substitutes – Same voltage rating (25 V) with variations in series, lifetime rating, ripple current capability, and physical dimensions. These are selected based on PCB layout constraints and thermal performance requirements.

Engineering Selection Recommendations

Direct Replacement (Same Form Factor):

For applications requiring identical PCB footprint and mechanical envelope, select from parts with matching lead spacing (0.197" / 5.00 mm), case diameter (0.394" / 10.00 mm), and height ≤ 0.492" (12.50 mm):

UVZ1V331MPD – Preferred upgrade substitute. Same series (UVZ), same physical dimensions, 35 V rating provides voltage margin, 2000 Hrs lifetime matches original, ROHS3 compliant.
UPW1E331MPD – Alternative with extended 5000 Hrs lifetime at 105°C, identical physical dimensions, improved ripple current handling (494 mA vs. 315 mA).
UPS1E331MPD – Compact alternative with 2000 Hrs lifetime, slightly taller (0.551" vs. 0.492"), suitable where minimal height increase is acceptable.

Space-Constrained Applications:

For designs with strict height limitations, UVY1E331MPD offers the lowest profile (0.512" height) but operates at reduced ripple current (275 mA) and shorter lifetime (1000 Hrs).

Extended Lifetime Applications:

For systems requiring enhanced thermal stability and longer operational life, UPJ1E331MPD6 and UPM1E331MPD6 provide 5000 Hrs lifetime but require PCB layout modification due to different lead spacing (0.138" / 4.60 mm) and larger height (0.650" to 0.669").

Automotive Applications:

UPM series parts (UPM1E331MPD, UPM1E331MPD6) carry AEC-Q200 qualification and are suitable for automotive-grade designs, though REACH status is affected.

Active Product Status:

UPW1E331MPD6 is the only part in this group with Active product status, making it the recommended choice for new designs requiring 330 µF, 25 V, 3000 Hrs lifetime specification.

Frequently Asked Questions (FAQ)

Q: Can I use UVZ1V331MPD (35 V) as a direct replacement for UVZ1E331MPD (25 V)?

A: Yes. Higher voltage rating capacitors are electrically compatible in circuits designed for lower voltage operation. UVZ1V331MPD maintains identical physical dimensions, series designation, and 2000 Hrs lifetime, providing improved voltage margin without circuit modification.

Q: What is the difference between UPJ1E331MPD and UPJ1E331MPD6?

A: Both are 330 µF, 25 V capacitors in the UPJ series with 3000 Hrs and 5000 Hrs lifetime respectively. UPJ1E331MPD uses 0.138" lead spacing and 0.827" height. UPJ1E331MPD6 uses 0.197" lead spacing and 0.650" height. Lead spacing and height differences require PCB layout verification before substitution.

Q: Why does UPW1E331MPD6 have Active product status while others are Not For New Designs?

A: UPW1E331MPD6 represents Nichicon's current production offering for this capacitance and voltage specification. It is the recommended selection for new circuit designs. Older series (UVZ, UPJ, UPS, UVY) remain available for legacy system support but are not recommended for new development.

Q: Can I substitute a part with different lead spacing without PCB modification?

A: No. Lead spacing determines PCB hole pattern and cannot be changed without redesigning the circuit board. Parts with 0.138" (4.60 mm) lead spacing require different PCB layouts than parts with 0.197" (5.00 mm) lead spacing. Verify lead spacing compatibility before selection.

Q: What does the "6" suffix in part numbers like UPJ1E331MPD6 indicate?

A: The "6" suffix indicates an extended lifetime rating (typically 5000 Hrs @ 105°C) compared to the base part number without suffix. It may also indicate packaging or manufacturing date code variations. Consult Nichicon datasheets for specific suffix definitions.

Q: Are all listed substitutes ROHS3 compliant?

A: Yes. All parts in this comparison table are ROHS3 compliant. REACH status varies: UPM series parts show REACH Affected status, while other series show REACH Unaffected. Verify REACH compliance requirements for your application before final selection.

Q: Which substitute offers the best ripple current performance?

A: UPM1E331MPD6 provides the highest ripple current at 630 mA @ 120 Hz, followed by UPJ1E331MPD at 610 mA @ 120 Hz. Original UVZ1E331MPD operates at 315 mA. Higher ripple current capability reduces thermal stress in high-frequency switching applications.

Q: Can I use UVY1E331MPD in a high-ripple-current application?

A: No. UVY1E331MPD is rated for only 275 mA ripple current @ 120 Hz, below the original part's 315 mA specification. This part is suitable only for low-ripple applications or where extended lifetime is not required (1000 Hrs @ 105°C).
