UPJ1E331MPD1TD Equivalent & Substitute Parts

Part Overview

The UPJ1E331MPD1TD is a 330 µF, 25 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is classified as Not For New Designs, indicating it has been superseded in Nichicon's product portfolio. Finding equivalent and substitute parts is necessary for legacy system maintenance, repair operations, and applications where design flexibility permits component selection from alternative manufacturers or series within the same electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UPJ1E331MPD1TD is determined by the following critical parameters:

• Capacitance Value: 330 µF (exact match required)
• Voltage Rating: Minimum 25 V (equal or higher voltage ratings are acceptable)
• Tolerance: ±20% (matching tolerance class)
• Package Configuration: Radial, Can with 0.138" (4.60 mm) lead spacing
• Case Diameter: 0.315" (8.00 mm)
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C to 105°C (minimum requirement)

Substitute parts are grouped into two categories:

Direct Equivalents (same voltage rating, 25 V): UPJ1E331MPD, UPM1E331MPD1TA, and UPM1E331MPD1TD maintain identical electrical specifications and physical footprints, differing only in packaging format or series designation.

Upgrade Substitutes (higher voltage rating, 35 V): 860080574014 and 860160574023 from Würth Elektronik provide enhanced voltage margin while maintaining all other critical parameters. These parts are suitable for direct replacement in applications where the higher voltage rating does not create design conflicts.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Voltage Rating)

UPM1E331MPD1TA and UPM1E331MPD1TD are preferred direct substitutes. Both are Nichicon UPM series components with identical electrical specifications to the UPJ1E331MPD1TD. The UPM series offers lower impedance (85 mOhms versus 130 mOhms), which provides improved high-frequency ripple current performance. Both parts carry AEC-Q200 automotive qualification, indicating enhanced reliability screening. The UPM1E331MPD1TD in Cut Tape packaging matches the original part's format most closely.

UPJ1E331MPD (Bulk packaging) is electrically identical but differs in packaging format. This option is suitable when tape packaging is not required.

For Voltage Upgrade (35 V Rating)

860080574014 (Würth Elektronik WCAP-ATLI) and 860160574023 (Würth Elektronik WCAP-ATLL) are upgrade substitutes with 35 V voltage rating. Both maintain 330 µF capacitance and ±20% tolerance. The 860160574023 offers extended lifetime (4000 Hrs @ 105°C versus 3000 Hrs) and is classified as Active product status, ensuring long-term availability. The 860080574014 provides superior impedance performance (41 mOhms) for high-frequency applications.

Both Würth parts are ROHS3 compliant and suitable for general-purpose applications. Selection between these upgrade options depends on whether extended lifetime or lower impedance is prioritized for the application.

Frequently Asked Questions (FAQ)

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

A: Yes. Higher voltage ratings are acceptable substitutes provided all other parameters match. The 35 V rated parts (860080574014 and 860160574023) are direct mechanical and electrical replacements for the 25 V UPJ1E331MPD1TD. The higher voltage rating provides additional safety margin and does not negatively impact circuit performance.

Q: What is the difference between UPJ and UPM series capacitors?

A: Both are Nichicon aluminum electrolytic capacitors with identical capacitance, voltage, and tolerance specifications. The UPM series offers lower impedance (85 mOhms versus 130 mOhms) and includes AEC-Q200 automotive qualification. For general-purpose applications, either series is functionally equivalent.

Q: Does packaging format (Cut Tape versus Bulk) affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly processes. UPJ1E331MPD (Bulk) and UPJ1E331MPD1TD (Cut Tape) are electrically identical. Selection depends on manufacturing and procurement requirements.

Q: Why are some substitute parts marked as "Not For New Designs"?

A: This status indicates the manufacturer has superseded the part in their active product line. However, these parts remain suitable for legacy system repair and maintenance. For new designs, Active status parts such as 860080574014 and 860160574023 are recommended for long-term supply assurance.

Q: What does impedance mean, and why does it vary among substitutes?

A: Impedance (ESR) affects the capacitor's high-frequency ripple current handling capability. Lower impedance (41 mOhms in 860080574014) indicates better performance at high frequencies. For applications with significant high-frequency ripple current, lower impedance substitutes provide improved performance margins.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance certification, meeting environmental and hazardous substance restrictions for electronic components.
