Equivalent & Substitute Parts for UPJ1E331MPD

Part Overview

The UPJ1E331MPD is a 330 µF, 25 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is rated for 3000 hours at 105°C and is classified as Not For New Designs. Due to this product status, equivalent and substitute parts are necessary for ongoing production support and design continuity. Substitutes must maintain the same capacitance, voltage rating, polarization, and mechanical compatibility while meeting the electrical performance requirements of the original application.

Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)
Operating Temperature: -55°C to 105°C (exact match required)
RoHS Status: ROHS3 Compliant (exact match required)

Secondary Parameters (Allowable Variation):

Lifetime @ 105°C: 2000 Hrs minimum (base part specifies 3000 Hrs; higher ratings acceptable)
Lead Spacing: 0.138" (4.60mm) or 0.197" (5.00mm) (mechanical footprint variation)
Physical Dimensions: Variation permitted within radial can envelope
Ripple Current: Variation permitted (electrical performance parameter)
Impedance: Variation permitted (electrical performance parameter)
ESR: Variation permitted (electrical performance parameter)

Substitutes are grouped by manufacturer series and product status. Direct substitutes maintain identical lead spacing and physical dimensions. Similar substitutes may vary in physical dimensions or lead spacing but retain full electrical compatibility. Upgrade substitutes offer enhanced specifications or active product status while maintaining core electrical parameters.

Engineering Selection Recommendations

Direct Substitutes (Identical Footprint): UPJ1E331MPD1TD is a direct substitute with identical electrical and mechanical specifications, differing only in packaging format (Cut Tape vs. Bulk). Both maintain 3000 Hrs @ 105°C lifetime and 0.138" lead spacing.

Same-Series Alternatives (Nichicon UPJ/UPM/UPS/UPW): Parts within the same manufacturer family are substitutable when lead spacing and physical dimensions accommodate the application. UPJ1E331MPD6, UPM1E331MPD, UPM1E331MPD6, UPS1E331MPD, and UPW1E331MPD variants all meet core electrical requirements. UPW1E331MPD6 is the only Nichicon part with Active product status, offering extended availability.

Cross-Manufacturer Substitutes (Active Status): ELXV250ELL331MH20D, ELXV250ELL331MH20S (Chemi-Con), and EEU-FC1E331 (Panasonic) are active products meeting all electrical and mechanical compatibility criteria. These parts carry AEC-Q200 automotive qualification, providing enhanced reliability documentation. Selection depends on lead spacing requirements: ELXV series maintains 0.138" spacing; EEU-FC1E331 requires 0.197" spacing.

Lifetime Considerations: Parts rated for 2000 Hrs @ 105°C (UPS1E331MPD) meet minimum requirements but offer reduced thermal endurance compared to the base specification. Parts rated for 5000 Hrs @ 105°C (UPJ1E331MPD6, UPM1E331MPD6, UPW1E331MPD) provide extended operational margin.

Frequently Asked Questions (FAQ)

Q: Can UPJ1E331MPD be replaced with UPW1E331MPD6? A: Yes. Both parts maintain 330 µF, 25 V, ±20% tolerance, and identical lead spacing (0.138"). UPW1E331MPD6 offers Active product status and 3000 Hrs @ 105°C lifetime. Physical height differs (0.591" vs. 0.827"), requiring PCB layout verification.

Q: What is the difference between UPJ1E331MPD and UPJ1E331MPD6? A: Both are Nichicon UPJ series with identical electrical specifications. UPJ1E331MPD6 features extended 5000 Hrs @ 105°C lifetime and larger physical dimensions (0.394" Dia, 0.650" Height vs. 0.315" Dia, 0.827" Height). Lead spacing differs (0.197" vs. 0.138"), requiring PCB footprint compatibility verification.

Q: Are Chemi-Con ELXV and Panasonic EEU-FC parts suitable replacements? A: Yes, both manufacturers' parts meet all core electrical parameters (330 µF, 25 V, ±20%, Polar, Through Hole, Radial Can). ELXV250ELL331MH20D and ELXV250ELL331MH20S maintain 0.138" lead spacing. EEU-FC1E331 requires 0.197" lead spacing. Both carry AEC-Q200 automotive qualification.

Q: Can UPS1E331MPD substitute for UPJ1E331MPD? A: Electrical substitution is valid (330 µF, 25 V, ±20%, Polar). However, UPS1E331MPD specifies 2000 Hrs @ 105°C lifetime versus 3000 Hrs for the base part, representing reduced thermal endurance. Lead spacing differs (0.197" vs. 0.138"), requiring PCB layout verification. Use only when thermal duty cycle permits lower lifetime rating.

Q: What packaging formats are available? A: UPJ1E331MPD1TD is supplied in Cut Tape (CT) format. All other listed parts are supplied in Bulk packaging. Packaging format does not affect electrical or mechanical compatibility; selection depends on assembly process requirements.

Q: Are all substitutes RoHS3 compliant? A: Yes. All listed parts maintain ROHS3 Compliant status. REACH status varies: Nichicon UPJ and UPS series are REACH Unaffected; Nichicon UPM series and Chemi-Con ELXV series are REACH Affected; Panasonic EEU-FC1E331 is REACH Unaffected. Verify REACH compliance requirements for your application jurisdiction.
