Substitute Part Grouping Explanation

Substitution of the UPS1V331MPD1TD is determined by strict equivalence in the following parameters:

Capacitance: 330 µF (exact match required)
Voltage Rating: 35 V minimum (higher voltage ratings are acceptable as upgrades)
Tolerance: ±20% (standard tolerance for this category)
Polarization: Polar (electrolytic capacitors)
Package Type: Radial, Can (through-hole configuration)
Lead Spacing: 0.197" (5.00 mm) (PCB footprint compatibility)
Physical Dimensions: 0.394" Dia × 0.689" Height maximum (board space constraints)
Mounting Type: Through Hole (assembly process compatibility)

Substitute parts are grouped into two categories:

Direct Equivalents: Same capacitance, voltage, and physical dimensions with identical or improved electrical performance.
Voltage Upgrades: Same capacitance and physical dimensions but with higher voltage ratings (50 V), suitable for applications with voltage margin requirements.

Engineering Selection Recommendations

For Direct Replacement (35 V Rating):

The 860080575015 (Würth Elektronik WCAP-ATLI series) and 860160575024 (Würth Elektronik WCAP-ATLL series) are preferred substitutes. Both are Active status components with extended lifetime ratings (5000 and 6000 hours respectively at 105°C) compared to the original 2000-hour specification. These parts maintain identical physical dimensions and lead spacing, ensuring PCB compatibility without layout modifications.

The EEU-FC1V331B (Panasonic FC series) is an Active status alternative with AEC-Q200 automotive qualification. It provides 3000-hour lifetime at 105°C and improved impedance characteristics (68 mOhms). Height is 0.669" (17.00 mm), which is within the 0.689" maximum specification.

The MAL214630331E3 (Vishay 146 RTI series) is an Active status component with AEC-Q200 automotive qualification and extended temperature operation to 125°C. Lifetime is rated at 2500 hours at 125°C, providing thermal margin for high-temperature applications.

For Voltage Upgrade (50 V Rating):

The EEU-HD1H331B (Panasonic HD series) provides a 50 V rating while maintaining the same 330 µF capacitance and physical footprint. This upgrade is suitable for applications requiring additional voltage margin or operating in higher voltage environments. Product status is Active.

Avoid:

UPW1V331MPD1TD and UKA1H331MPD1TD are classified as "Not For New Designs" and should not be selected for new applications, despite improved performance characteristics in some parameters.

Frequently Asked Questions (FAQ)

Q: Can I use a 50 V rated capacitor in place of a 35 V rated capacitor?

A: Yes. A higher voltage rating provides additional safety margin and is electrically compatible. The EEU-HD1H331B (50 V) and UKA1H331MPD1TD (50 V) are direct physical substitutes for the UPS1V331MPD1TD (35 V). However, verify that the application circuit does not impose space or cost constraints that would be negatively affected by the voltage upgrade.

Q: What is the significance of "Not For New Designs" status?

A: This designation indicates the manufacturer has discontinued the product line for new applications. Existing inventory may remain available, but the component will not receive design updates or extended support. For new designs, select Active status alternatives such as 860080575015, 860160575024, EEU-FC1V331B, or MAL214630331E3.

Q: Are all substitute parts pin-compatible with the original UPS1V331MPD1TD?

A: Yes. All listed substitutes maintain the same lead spacing (0.197" / 5.00 mm), physical diameter (0.394" / 10.00 mm), and radial through-hole package configuration. PCB footprints are directly compatible. Note that EEU-FC1V331B has a maximum height of 0.669" compared to 0.689" for other parts; verify clearance in applications with tight vertical constraints.

Q: Which substitute offers the best performance improvement?

A: The 860080575015 (Würth Elektronik) provides the lowest impedance (38 mOhms) and highest ripple current capability (1.4 A @ 100 kHz) with 5000-hour lifetime at 105°C. The EEU-FC1V331B and UPW1V331MPD1TD offer equivalent impedance (68 mOhms) with comparable ripple current performance.

Q: Can I use these substitutes in automotive applications?

A: The EEU-FC1V331B and MAL214630331E3 carry AEC-Q200 automotive qualification. Other substitutes are rated for general purpose applications. Verify automotive qualification requirements with your application specifications before selection.

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

A: Both 860080575015 (WCAP-ATLI) and 860160575024 (WCAP-ATLL) are 330 µF, 35 V, radial through-hole capacitors. The WCAP-ATLI series offers lower impedance (38 mOhms) and higher ripple current (1.4 A @ 100 kHz) with 5000-hour lifetime. The WCAP-ATLL series provides extended 6000-hour lifetime with slightly higher impedance (150 mOhms). Select based on ripple current and thermal cycling requirements.
