Substitute Part Grouping Explanation

Substitution for the UHE1C331MPD1TA is determined by strict equivalence across the following parameters:

Capacitance Value: 330 µF (exact match required)
Voltage Rating: 16 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime Rating: 7000 Hrs @ 105°C (exact match required)
Operating Temperature Range: -40°C ~ 105°C (exact match required)
Polarization: Polar (exact match required)
Package Configuration: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)
Lead Spacing: 0.138" (4.60mm) (exact match required)
Physical Dimensions: 0.315" Dia (8.00mm), Height 0.512" (13.00mm) (exact match required)
Compliance: ROHS3 Compliant (exact match required)

Two substitute parts meet these criteria: UHE1C331MPD1TD (Nichicon) and 860040374005 (Würth Elektronik).

Engineering Selection Recommendations

UHE1C331MPD1TD is a direct parametric equivalent manufactured by Nichicon within the same UHE series. Both the main part and this substitute carry "Not For New Designs" status. Selection between UHE1C331MPD1TA and UHE1C331MPD1TD is based on inventory availability and procurement lead times, as electrical and mechanical specifications are identical.

860040374005 is manufactured by Würth Elektronik under the WCAP-ATUL series and meets all parametric requirements for substitution. This part carries "Active" product status, making it suitable for applications requiring long-term component availability. Minor variations in ripple current (450 mA vs. 448 mA @ 120 Hz) and impedance (140 mOhms vs. 130 mOhms) remain within acceptable engineering tolerances for general-purpose applications. Both parts maintain ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can UHE1C331MPD1TD be used as a direct replacement for UHE1C331MPD1TA?

A: Yes. Both parts are manufactured by Nichicon, share identical electrical and mechanical specifications, and are pin-compatible with matching lead spacing (4.60mm) and physical dimensions (0.315" Dia, 0.512" height). No circuit modifications are required.

Q: Is 860040374005 a suitable substitute for UHE1C331MPD1TA?

A: Yes. The Würth Elektronik 860040374005 meets all parametric requirements: 330 µF capacitance, 16 V rating, ±20% tolerance, 7000 Hrs @ 105°C lifetime, identical physical dimensions, and through-hole radial configuration. The part is pin-compatible and ROHS3 compliant.

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

A: This designation indicates the UHE1C331MPD1TA is in mature or end-of-life phase. For new product development, 860040374005 (Active status) is the recommended choice. For existing designs or maintenance applications, both Nichicon substitutes remain available.

Q: Are there differences in ripple current handling between the main part and substitutes?

A: The main part and UHE1C331MPD1TD both specify 448 mA @ 120 Hz. The Würth Elektronik 860040374005 specifies 450 mA @ 120 Hz, representing a negligible difference of 2 mA. Both are suitable for general-purpose applications within the specified operating parameters.

Q: Do all three parts have identical physical footprints?

A: Yes. All three parts share identical lead spacing (0.138" / 4.60mm), diameter (0.315" / 8.00mm), and maximum seated height (0.512" / 13.00mm). PCB layout modifications are not required when substituting between these parts.
