Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UPM2A390MPD6TD is determined by strict electrical and mechanical parameter matching:

Critical Matching Parameters:

• Capacitance value: 39 µF (exact match required)
• Voltage rating: 100 V (minimum acceptable)
• Tolerance: ±20% (electrical performance window)
• Polarization: Polar (circuit compatibility)
• Lead spacing: 0.197" (5.00 mm) (PCB layout compatibility)
• Package type: Radial, Can (physical form factor)
• Mounting type: Through Hole (assembly process compatibility)

The UPJ2A390MPD6TD meets all critical matching parameters and qualifies as a direct substitute based on these electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The UPJ2A390MPD6TD is electrically and mechanically compatible with the UPM2A390MPD6TD for direct substitution. Both parts are manufactured by Nichicon, share identical capacitance, voltage rating, tolerance, temperature range, and lead spacing specifications. Both are ROHS3 compliant and rated for 5000-hour lifetime at 105°C.

The primary difference between these parts is application classification: the UPM series is designated for automotive applications with AEC-Q200 certification, while the UPJ series is designated for general purpose applications. The UPJ2A390MPD6TD has lower ripple current ratings (193 mA @ 120 Hz and 337 mA @ 10 kHz compared to 285 mA and 500 mA respectively), which may be a consideration in high-ripple-current circuit environments.

For applications requiring automotive-grade reliability and AEC-Q200 compliance, the original UPM2A390MPD6TD specification should be maintained. For general purpose applications where automotive certification is not required, the UPJ2A390MPD6TD provides functional equivalence with adequate performance margins.

Frequently Asked Questions (FAQ)

Q: Can the UPJ2A390MPD6TD replace the UPM2A390MPD6TD in automotive applications?

A: The UPJ2A390MPD6TD meets all electrical and mechanical compatibility requirements. However, the UPM series carries AEC-Q200 automotive certification while the UPJ series does not. Selection depends on whether automotive-grade qualification is a system requirement.

Q: What is the physical difference between these parts?

A: The seated height differs slightly: UPM2A390MPD6TD is 0.669" (17.00 mm) maximum, while UPJ2A390MPD6TD is 0.650" (16.50 mm) maximum. Both share identical lead spacing (0.197" / 5.00 mm) and diameter (0.394" / 10.00 mm), ensuring PCB layout compatibility.

Q: Are there ripple current limitations when substituting?

A: The UPJ2A390MPD6TD has lower ripple current ratings than the UPM2A390MPD6TD. In circuits with ripple currents exceeding 193 mA @ 120 Hz or 337 mA @ 10 kHz, the UPJ variant may not provide equivalent performance. Circuit ripple current requirements should be verified before substitution.

Q: Are both parts RoHS compliant?

A: Yes, both the UPM2A390MPD6TD and UPJ2A390MPD6TD are ROHS3 compliant.

Q: What is the lead spacing significance for substitution?

A: Lead spacing of 0.197" (5.00 mm) is a critical mechanical parameter that determines PCB hole pattern compatibility. Both parts share identical lead spacing, ensuring direct PCB mounting compatibility without layout modification.
