Key Parameters

Substitute Part Grouping Explanation

Substitution of the UPM1K820MPD is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Capacitance (82 µF), tolerance (±20%), and rated voltage (80 V) must match exactly
• Physical Compatibility: Lead spacing (5.00mm), case diameter (10.00mm), and mounting type (Through Hole, Radial) must be identical to ensure PCB fit without redesign
• Thermal Performance: Operating temperature range (-55°C ~ 105°C) and lifetime rating (5000 Hrs @ 105°C) must be maintained
• Polarization: Polar configuration must be preserved for circuit function
• Compliance: RoHS3 compliance is required; environmental and regulatory status must be verified

The UPJ1K820MPD1TD meets all these criteria and qualifies as a direct substitute based on matching electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The UPJ1K820MPD1TD is a direct functional equivalent to the UPM1K820MPD. Both parts are manufactured by Nichicon and share identical electrical specifications, thermal ratings, and physical dimensions. The UPJ1K820MPD1TD maintains ROHS3 compliance and equivalent impedance characteristics.

The primary difference is packaging format: the UPM1K820MPD is supplied in Bulk packaging, while the UPJ1K820MPD1TD is supplied in Cut Tape (CT) format. This distinction affects procurement and handling but does not impact electrical or mechanical performance in the application.

Both parts carry "Not For New Designs" status, indicating they are legacy components. Selection between them should be based on packaging availability and procurement requirements rather than technical performance, as electrical and mechanical compatibility is complete.

Frequently Asked Questions (FAQ)

Q: Can the UPJ1K820MPD1TD replace the UPM1K820MPD in existing designs?

A: Yes. The UPJ1K820MPD1TD is electrically and mechanically equivalent. All critical parameters—capacitance, voltage rating, temperature range, physical dimensions, and lead spacing—are identical. Direct substitution is possible without circuit modification.

Q: What is the difference between Bulk and Cut Tape packaging?

A: Bulk packaging supplies loose components, while Cut Tape (CT) packaging provides components on adhesive tape in cut lengths. Both formats contain identical components; the difference is in handling and procurement logistics. Bulk is typically used for manual assembly or small quantities, while Cut Tape is suited for automated pick-and-place equipment.

Q: Are there any height clearance concerns with the UPJ1K820MPD1TD?

A: The UPJ1K820MPD1TD has a maximum seated height of 0.846" (21.50mm) compared to 0.866" (22.00mm) for the UPM1K820MPD. This 0.5mm difference is negligible for most applications and does not create clearance issues in standard PCB layouts.

Q: Do both parts meet automotive compliance requirements?

A: The UPM1K820MPD carries AEC-Q200 certification for automotive applications. The UPJ1K820MPD1TD does not list AEC-Q200 certification but is designated for General Purpose applications. If AEC-Q200 certification is a mandatory requirement, the UPM1K820MPD should be retained. For non-automotive or non-certified applications, the UPJ1K820MPD1TD is suitable.

Q: What is the ripple current difference between these parts?

A: The UPM1K820MPD is rated for 395 mA @ 120 Hz and 620 mA @ 10 kHz. The UPJ1K820MPD1TD is rated for 284 mA @ 120 Hz and 447 mA @ 10 kHz. If the application requires the higher ripple current capability of the UPM1K820MPD, this difference must be evaluated against circuit demands.
