Engineering Selection Recommendations

For Direct Replacement (Same Electrical Performance): UPJ1V331MPD1AA is the recommended choice. This part maintains identical electrical specifications (330 µF, 35 V, ±20%, 5000 Hrs @ 105°C) with the same physical footprint and lead spacing. The critical advantage is Active product status, ensuring long-term availability and supply chain stability for new designs or production continuity.

For PCB Footprint Compatibility with Identical Lead Spacing (0.197" / 5.00 mm): UPW1V331MPD offers superior performance with lower impedance (68 mOhms vs. 96 mOhms), improved ripple current handling at high frequency (1.05 A @ 100 kHz), and compact height (0.630" vs. 0.846"). This part is suitable when space constraints or thermal performance improvements are beneficial.

UPM1V331MPD provides the lowest impedance (60 mOhms) among Nichicon equivalents with AEC-Q200 automotive qualification, making it appropriate for automotive applications requiring enhanced reliability metrics.

For Upgraded Voltage Rating and Extended Lifetime: B41888C6337M000 (EPCOS/TDK) provides 50 V rating with 7000-hour lifetime at 105°C, AEC-Q200 automotive qualification, and superior impedance (75 mOhms). This upgrade is suitable for applications requiring higher voltage margin or extended operational life.

B41858C6337M000 (EPCOS/TDK) offers 50 V rating with 5000-hour lifetime and maintains compatibility with the original PCB footprint.

For Reduced Lifetime Applications: UPS1V331MPD is acceptable only when application requirements permit 2000-hour lifetime at 105°C. This part exhibits higher impedance (140 mOhms) and reduced ripple current capacity, limiting its use to non-critical general-purpose applications.

Packaging Considerations: UPJ1V331MPD1TD (Cut Tape packaging) is functionally equivalent to the bulk-packaged UPJ1V331MPD, suitable for automated assembly processes requiring tape-and-reel format.

UPJ1V331MHD6 and UPM1V331MHD6 feature larger physical dimensions (0.492" diameter) with reduced height, applicable only when PCB layout accommodates the different form factor.

UPW1V331MPD6 has non-standard lead spacing (0.138" / 4.60 mm), incompatible with standard 5.00 mm pitch PCB designs.

Frequently Asked Questions (FAQ)

Q: Can UPJ1V331MPD be replaced with UPJ1V331MPD1AA? A: Yes. UPJ1V331MPD1AA is a direct parametric equivalent with identical electrical specifications (330 µF, 35 V, ±20%, 5000 Hrs @ 105°C) and physical dimensions. The primary advantage is Active product status, ensuring continued availability. Both parts share the same lead spacing (0.197" / 5.00 mm) and radial can package, making them pin-compatible.

Q: What is the difference between Nichicon UPJ, UPM, and UPW series? A: All three series meet the core specifications of 330 µF, 35 V, ±20% tolerance, and 5000-hour lifetime at 105°C. Key differences include impedance characteristics (UPJ: 96 mOhms, UPM: 60 mOhms, UPW: 68 mOhms), physical dimensions, and application focus. UPM series includes AEC-Q200 automotive qualification. Selection depends on ripple current requirements and thermal performance needs.

Q: Can UPJ1V331MPD be used in automotive applications? A: The UPJ1V331MPD itself is not AEC-Q200 qualified. For automotive applications, UPM1V331MPD or UPM1V331MHD6 are appropriate substitutes, both carrying AEC-Q200 certification. Alternatively, EPCOS/TDK B41858C6337M000 or B41888C6337M000 provide automotive-grade reliability with higher voltage ratings.

Q: What does "Not For New Designs" status mean? A: This designation indicates the part has been superseded in the manufacturer's portfolio. While existing inventory remains available, Nichicon recommends using newer alternatives for new product development. UPJ1V331MPD1AA (Active status) is the recommended replacement for new designs.

Q: Are EPCOS/TDK parts compatible with the original PCB layout? A: B41858C6337M000 and B41888C6337M000 maintain the same lead spacing (0.197" / 5.00 mm) and radial can package, ensuring PCB footprint compatibility. However, both parts have 50 V ratings (vs. 35 V original), which is acceptable for designs operating at 35 V or lower. Physical height differs slightly (0.866" vs. 0.846"), requiring verification of vertical clearance in the assembly.

Q: Why does UPS1V331MPD have lower ripple current ratings? A: UPS1V331MPD is rated for 2000 hours at 105°C (vs. 5000 hours for UPJ/UPM/UPW series) and exhibits higher impedance (140 mOhms). These characteristics reflect a lower-performance tier within Nichicon's portfolio. This part is suitable only for non-critical applications where extended lifetime is not required.

Q: Can UPW1V331MPD6 be used as a substitute? A: UPW1V331MPD6 has non-standard lead spacing (0.138" / 4.60 mm) compared to the original 0.197" (5.00 mm). This part is incompatible with PCB designs intended for standard 5.00 mm pitch. Use only if PCB layout has been specifically designed for 4.60 mm lead spacing.

Q: What is the significance of impedance differences among substitutes? A: Impedance directly affects ripple current handling and thermal performance. Lower impedance (UPM series at 60 mOhms) provides superior high-frequency ripple current capacity and reduced heat generation. Higher impedance (UPS series at 140 mOhms) limits ripple current handling. Selection should align with application ripple current requirements at operating frequencies.

Q: Is RoHS3 compliance maintained across all substitutes? A: Yes. All listed substitutes maintain ROHS3 compliance. EPCOS/TDK parts additionally specify MSL (Moisture Sensitivity Level) as 1 (Unlimited) or Not Applicable, indicating compatibility with standard PCB assembly processes.
