Substitute Part Grouping Explanation

Substitution eligibility for the UPM1K331MHD6TN is determined by the following critical parameters:

Capacitance Value: 330 µF (exact match required)
Voltage Rating: Minimum 80 V (equal or higher acceptable)
Tolerance: ±20% (matching tolerance class)
Polarization: Polar (radial configuration)
Lead Spacing: 0.295" (7.50 mm)
Package Diameter: 0.630" (16.00 mm)
Mounting Type: Through Hole
RoHS Compliance: ROHS3 Compliant

Substitutes are grouped into two categories: direct equivalents (matching all electrical and mechanical parameters) and upgrades (higher voltage rating or extended lifetime with identical physical footprint).

Engineering Selection Recommendations

Direct Equivalent - UPJ1K331MHD6TN: This part matches all critical electrical parameters (330 µF, 80 V, ±20% tolerance, 5000 Hrs @ 105°C) and physical dimensions. The primary difference is application classification (General Purpose vs. Automotive AEC-Q200). This substitute is suitable for non-automotive applications or where AEC-Q200 certification is not required. Height difference of 0.020" (0.50 mm) is within typical PCB layout tolerances.

Direct Equivalent - UPM1K331MHD6: This part is identical to the main component in all electrical and mechanical specifications, differing only in packaging format (Bulk vs. Cut Tape). It maintains AEC-Q200 automotive rating and identical physical footprint. Selection depends on procurement and assembly requirements.

Upgrade - UPW2A331MHD1TN: This part provides enhanced performance with 100 V voltage rating (25% higher than the original 80 V) and extended lifetime of 8000 hours at 105°C (60% longer than the original 5000 hours). Physical footprint and lead spacing remain identical. This upgrade is applicable when higher voltage margin or extended operational life is required. REACH status differs (Unaffected vs. Affected), which may impact supply chain considerations.

All substitute parts maintain ROHS3 compliance and identical through-hole radial mounting configuration, ensuring direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can UPJ1K331MHD6TN replace UPM1K331MHD6TN in automotive applications?

A: UPJ1K331MHD6TN lacks AEC-Q200 automotive certification. If AEC-Q200 compliance is a design requirement, this substitute is not suitable. For non-automotive or general-purpose applications, it is electrically and mechanically compatible.

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

A: Cut Tape (CT) packaging provides individual component strips suitable for automated pick-and-place assembly. Bulk packaging is supplied in loose form for manual handling or alternative assembly processes. Electrical and mechanical specifications are identical; selection depends on assembly methodology.

Q: Is UPW2A331MHD1TN a direct replacement or an upgrade?

A: UPW2A331MHD1TN is an upgrade. It provides higher voltage rating (100 V vs. 80 V) and extended lifetime (8000 Hrs vs. 5000 Hrs @ 105°C). Physical footprint and lead spacing are identical, enabling direct PCB substitution. Use this part when enhanced performance margins are required.

Q: Will UPJ1K331MHD6TN fit the same PCB layout as UPM1K331MHD6TN?

A: Yes, with minor consideration. Lead spacing (0.295" / 7.50 mm) and package diameter (0.630" / 16.00 mm) are identical. Height difference is 0.020" (0.50 mm) maximum, which is within standard PCB clearance tolerances for through-hole components.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitutes (UPJ1K331MHD6TN, UPM1K331MHD6, UPW2A331MHD1TN) are ROHS3 compliant, matching the original part's environmental compliance status.

Q: What does "Not For New Designs" status mean?

A: This designation indicates the part is in mature or end-of-life phase. Nichicon continues to support existing production but does not recommend this part for new circuit designs. Substitute parts listed here provide continuity for existing applications while offering alternatives for new designs.
