Substitute Part Grouping Explanation

Substitution of the UVK1H331MPD1TD is determined by strict equivalence in the following parameters: capacitance (330 µF), voltage rating (50 V), tolerance (±20%), package type (Radial, Can), lead spacing (5.00 mm), case diameter (10.00 mm), and mounting type (Through Hole). These parameters define the physical and electrical compatibility required for direct replacement in PCB designs.

Substitute parts are grouped into three categories:

Upgrade Parts (Nichicon Series): UFW1H331MPD1TD, UKA1H331MPD1TD, and UKW1H331MPD1TD maintain identical electrical and mechanical specifications while offering enhanced performance characteristics such as extended temperature ranges or improved ripple current handling.

Parametric Equivalents (Multi-Manufacturer): UVR1H331MPD1TD (Nichicon), 860010675019 (Würth Elektronik), and ESMG500ETD331MJ16S (Chemi-Con) meet all core electrical and mechanical parameters with identical lifetime ratings at 85°C.

Direct Equivalent (Active Product): ECA-1HM331B (Panasonic Electronic Components) provides full parametric equivalence with Active product status and is available in higher inventory quantities.

Enhanced Alternatives: 860020675021 (Würth Elektronik) and EEU-HD1H331B (Panasonic Electronic Components) offer extended temperature operating ranges and higher lifetime ratings at 105°C, suitable for applications requiring improved thermal performance.

Engineering Selection Recommendations

For applications requiring direct replacement with minimal risk, ECA-1HM331B (Panasonic) is the preferred choice. It maintains full parametric equivalence to UVK1H331MPD1TD, carries Active product status, and offers the highest inventory availability at 82,918 pieces.

For designs operating in extended temperature environments or requiring enhanced thermal performance, EEU-HD1H331B (Panasonic) or 860020675021 (Würth Elektronik) are suitable alternatives. Both provide 2000 Hrs lifetime at 105°C and extended operating temperature ranges (-55°C to 105°C for EEU-HD1H331B; -40°C to 105°C for 860020675021).

All substitute parts listed are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Nichicon alternatives (UFW1H331MPD1TD, UKA1H331MPD1TD, UKW1H331MPD1TD, UVR1H331MPD1TD) remain available but retain Not For New Designs status. Multi-manufacturer parametric equivalents (860010675019, ESMG500ETD331MJ16S) carry Active status and provide additional sourcing flexibility.

Frequently Asked Questions (FAQ)

Q: Can UVK1H331MPD1TD be replaced with ECA-1HM331B in existing designs?

A: Yes. ECA-1HM331B meets all core electrical and mechanical parameters: 330 µF capacitance, 50 V voltage rating, ±20% tolerance, identical lead spacing (5.00 mm), case diameter (10.00 mm), and through-hole mounting. The seated height differs by 0.5 mm (17.00 mm vs 17.50 mm), which is within typical PCB layout tolerances for radial capacitors.

Q: What is the difference between parametric equivalents and direct equivalents?

A: Direct equivalents (ECA-1HM331B) provide identical electrical and mechanical specifications with Active product status. Parametric equivalents (860010675019, ESMG500ETD331MJ16S, UVR1H331MPD1TD) meet all core electrical and mechanical requirements but may originate from different manufacturers or product series.

Q: Should I use EEU-HD1H331B or 860020675021 for thermal-demanding applications?

A: Both parts support 2000 Hrs lifetime at 105°C and extended operating temperature ranges. EEU-HD1H331B operates from -55°C to 105°C; 860020675021 operates from -40°C to 105°C. Selection depends on the minimum operating temperature requirement of your application.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic components.

Q: What packaging formats are available for these substitutes?

A: Most substitutes are supplied in Cut Tape (CT) packaging. ECA-1HM331B and ESMG500ETD331MJ16S are supplied in Tape & Box (TB) format. Packaging format does not affect electrical or mechanical compatibility.

Q: Can I use Nichicon upgrade parts (UFW1H331MPD1TD, UKW1H331MPD1TD) as direct replacements?

A: Yes. These Nichicon series maintain identical electrical and mechanical specifications to UVK1H331MPD1TD. However, they retain Not For New Designs status. For new designs, Active-status alternatives such as ECA-1HM331B are recommended.
