Substitute Part Grouping Explanation

Substitution for the UPM1E331MPD6TD is determined by the following critical parameters:

Capacitance: 330 µF (exact match required)
Tolerance: ±20% (exact match required)
Voltage Rating: Minimum 25 V (higher ratings acceptable for voltage derating)
Lead Spacing: 0.197" (5.00mm) (exact match for PCB compatibility)
Package Configuration: Radial, Can, Through Hole (exact match required)
Operating Temperature Range: -55°C ~ 105°C (exact match required)
Polarization: Polar (exact match required)

The substitute parts listed meet all these criteria. Voltage ratings of 35 V represent acceptable upgrades, as they provide additional safety margin while maintaining the same physical footprint and electrical characteristics. All substitutes maintain ROHS3 compliance and the same lead spacing and package dimensions.

Engineering Selection Recommendations

For Active Production and New Designs:

The Würth Elektronik parts 860080575015 and 860160575024 are preferred substitutes due to their Active product status. Both components are suitable for long-term supply chain stability and new design implementations.

860160575024 (Würth Elektronik WCAP-ATLL Series) offers extended lifetime rating of 6000 hours at 105°C compared to the 5000-hour rating of the original part, providing enhanced reliability margin for demanding applications.

860080575015 (Würth Elektronik WCAP-ATLI Series) maintains the 5000-hour lifetime specification while offering lower impedance characteristics.

For Direct Replacement in Existing Designs:

The UPW1V331MPD1TD (Nichicon UPW Series) provides a direct functional equivalent with identical electrical specifications and the same 5000-hour lifetime rating. However, this part carries "Not For New Designs" status, limiting its use to legacy system maintenance.

All substitute parts maintain identical capacitance, tolerance, lead spacing, and package configuration. The height increase from 0.669" to 0.689" for substitute parts must be verified against PCB clearance constraints in the target application.

Frequently Asked Questions (FAQ)

Q: Can I use a 35 V rated capacitor in place of the 25 V original?

A: Yes. A 35 V rated capacitor is a valid substitute for a 25 V application. The higher voltage rating provides additional safety margin and does not negatively impact circuit performance. The capacitance, tolerance, and physical dimensions remain identical.

Q: What is the significance of the height difference between the original and substitute parts?

A: The original UPM1E331MPD6TD has a maximum seated height of 0.669" (17.00mm), while substitute parts measure 0.689" (17.50mm). This 0.02" (0.50mm) difference must be evaluated against PCB layout constraints, component clearances, and enclosure dimensions. In most applications, this difference is negligible; however, space-constrained designs require verification.

Q: Are the Würth Elektronik parts suitable for automotive applications?

A: The Würth Elektronik 860080575015 and 860160575024 are rated for General Purpose applications. The original UPM1E331MPD6TD carries AEC-Q200 automotive certification. For applications requiring automotive-grade qualification, this distinction should be considered during design review.

Q: What is the difference between the two Würth Elektronik substitutes?

A: Both parts are 330 µF, 35 V aluminum electrolytic capacitors with identical physical dimensions and lead spacing. The primary differences are: 860160575024 (WCAP-ATLL Series) offers 6000-hour lifetime at 105°C versus 5000 hours for 860080575015 (WCAP-ATLI Series). The impedance and ripple current ratings differ slightly between the two series.

Q: Can I use these substitutes in designs originally specified for the UPM1E331MPD6TD?

A: Yes, all listed substitutes are electrically and mechanically compatible. The identical capacitance, tolerance, lead spacing, and package configuration ensure direct PCB compatibility. The height difference of 0.02" must be cleared with mechanical design review.
