Substitute Part Grouping Explanation

Substitution eligibility for the UFW1J331MPD1TD is determined by strict equivalence across the following parameters: capacitance (330 µF), voltage rating (63 V), tolerance (±20%), package type (radial can), mounting type (through hole), lead spacing (5.00 mm), case diameter (10.00 mm), and polarization (polar). All substitute parts must maintain these core electrical and mechanical specifications to ensure direct compatibility in PCB layouts and circuit applications.

The substitute parts are grouped as follows:

Nichicon Series Upgrades: UVK1J331MPD1TD, UVR1J331MPD1TD, and UKW1J331MPD1TD are Nichicon alternatives within the same manufacturer ecosystem, offering improved ripple current performance or different application classifications while maintaining identical core parameters.

Cross-Manufacturer Direct Equivalent: 860010775019 (Würth Elektronik WCAP-ATG8 series) provides an active product status alternative with equivalent electrical and mechanical specifications.

Panasonic Upgrades: ECA-1JHG331B and ECA-1JM331B are Panasonic alternatives with active product status, offering enhanced thermal performance or alternative series classifications.

Engineering Selection Recommendations

All substitute parts listed maintain identical core electrical specifications (330 µF, 63 V, ±20% tolerance) and mechanical dimensions (5.00 mm lead spacing, 10.00 mm case diameter, 22.00 mm height maximum). All parts are ROHS3 compliant and REACH unaffected.

For applications requiring active product status and long-term supply assurance, 860010775019 (Würth Elektronik), ECA-1JHG331B, and ECA-1JM331B are preferred selections. The Würth part offers the advantage of active product classification with minimal height variation (21.50 mm vs. 22.00 mm). The Panasonic ECA-1JHG331B provides extended operating temperature range (-55°C ~ 105°C) and higher thermal rating (2000 Hrs @ 105°C), suitable for applications with elevated ambient temperature requirements.

For direct Nichicon ecosystem continuity, UVK1J331MPD1TD, UVR1J331MPD1TD, and UKW1J331MPD1TD maintain identical specifications while offering improved ripple current performance in specific frequency bands.

Frequently Asked Questions (FAQ)

Q: Can UFW1J331MPD1TD be directly replaced with any of the listed substitutes?

A: Yes. All listed parts maintain identical capacitance (330 µF), voltage rating (63 V), tolerance (±20%), lead spacing (5.00 mm), case diameter (10.00 mm), and polarization. PCB layouts and circuit connections require no modification.

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

A: This designation indicates the UFW series has been superseded by Nichicon. For new designs, active product alternatives such as 860010775019, ECA-1JHG331B, or ECA-1JM331B are recommended to ensure long-term availability and manufacturer support.

Q: Are there height differences between substitutes?

A: The Würth Elektronik 860010775019 has a maximum seated height of 21.50 mm, compared to 22.00 mm for all other parts. This 0.50 mm difference is within typical PCB clearance tolerances but should be verified for space-constrained applications.

Q: Which substitute offers the best thermal performance?

A: The Panasonic ECA-1JHG331B (NHG-A series) provides the highest thermal rating at 2000 Hrs @ 105°C with an extended operating temperature range of -55°C ~ 105°C, compared to the standard -40°C ~ 85°C specification of the UFW1J331MPD1TD.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What ripple current differences exist between substitutes?

A: Ripple current performance varies by series and frequency. The Würth Elektronik 860010775019 delivers 1.04742 A @ 100 kHz, while Panasonic ECA-1JM331B provides 935 mA @ 10 kHz. Selection should align with specific circuit ripple current requirements at the operating frequency.
