Substitute Part Grouping Explanation

Substitution eligibility for the UPM1K390MPD is determined by strict equivalence across the following critical parameters:

• Capacitance value: 39 µF (exact match required)
• Voltage rating: 80 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Lifetime specification: 3000 Hrs @ 105°C (exact match required)
• Operating temperature range: -55°C ~ 105°C (exact match required)
• Package type: Radial, Can through-hole (exact match required)
• Physical dimensions: 0.315" Dia (8.00 mm), lead spacing 0.138" (4.60 mm) (exact match required)
• Impedance: 460 mOhms (exact match required)

The UPJ1K390MPD1TD meets all substitution criteria and is classified as a direct equivalent based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

The UPJ1K390MPD1TD is a direct functional equivalent to the UPM1K390MPD. Both components share identical electrical specifications, including capacitance, voltage rating, tolerance, lifetime rating, and operating temperature range. Physical dimensions are compatible for through-hole PCB mounting, with the substitute featuring a marginally reduced seated height (0.630" versus 0.650"), which presents no compatibility constraint for standard applications.

Both parts maintain ROHS3 compliance. The primary distinction lies in packaging format: the UPM1K390MPD is supplied in bulk, while the UPJ1K390MPD1TD is supplied in cut tape format. The substitute part is available in higher inventory quantity (1929 pcs versus 820 pcs), supporting production continuity.

The UPM1K390MPD carries automotive AEC-Q200 certification, while the UPJ1K390MPD1TD is designated for general-purpose applications. Both parts carry "Not For New Designs" status, indicating they are suitable for legacy system support and production continuation only.

Frequently Asked Questions (FAQ)

Q: Can the UPJ1K390MPD1TD replace the UPM1K390MPD in automotive applications?

A: The UPJ1K390MPD1TD meets all electrical and mechanical substitution criteria. The primary difference is application classification: the original part carries AEC-Q200 automotive certification, while the substitute is designated general-purpose. Compliance requirements for your specific automotive application must be evaluated independently.

Q: What is the impact of the height difference between these parts?

A: The UPJ1K390MPD1TD has a maximum seated height of 0.630" compared to 0.650" for the UPM1K390MPD. This 0.020" reduction presents no constraint for standard through-hole PCB layouts and does not affect electrical performance.

Q: How do ripple current specifications compare?

A: The UPJ1K390MPD1TD exhibits slightly lower ripple current ratings at both 120 Hz (156 mA versus 170 mA) and 10 kHz (272 mA versus 300 mA). Circuit designs must verify that actual ripple current demands do not exceed the substitute part's specifications.

Q: Does packaging format affect component performance?

A: No. Bulk and cut tape packaging formats do not affect electrical or mechanical performance. The packaging difference impacts only handling, storage, and assembly logistics.

Q: Are both parts suitable for new designs?

A: Both the UPM1K390MPD and UPJ1K390MPD1TD carry "Not For New Designs" status. These parts are appropriate for production continuation and legacy system support only. New designs should evaluate current-generation alternatives from the manufacturer's active product portfolio.
