Substitute Part Grouping Explanation

Substitution eligibility for the UVZ1H331MPD1TD is determined by strict equivalence across the following critical parameters:

Capacitance: 330 µF (exact match required)
Voltage Rating: 50 V (exact match required)
Tolerance: ±20% (exact match required)
Package Configuration: Radial, Can with identical lead spacing (0.197"), diameter (0.394"), and height (0.689")
Mounting Type: Through Hole
Polarization: Polar
Operating Temperature Range: -55°C ~ 105°C (minimum requirement)
Ripple Current @ 120 Hz: 410 mA (minimum requirement)
RoHS Compliance: ROHS3 Compliant

All identified substitute parts meet these core electrical and mechanical parameters. Variations in lifetime rating, ripple current at higher frequencies, and product status are noted but do not disqualify substitution when the primary parameters align.

Engineering Selection Recommendations

All five parts listed meet the core electrical and mechanical substitution criteria for the UVZ1H331MPD1TD. Selection should be based on the following factors:

Product Status Consideration: EKMG500ETD331MJ16S (Chemi-Con) and EEU-HD1H331B (Panasonic Electronic Components) carry Active product status, indicating ongoing manufacturer support and availability. UKA1H331MPD1TD and UVY1H331MPD1TD are Nichicon parts with Not For New Designs status, matching the main part's lifecycle classification.

Lifetime Rating: UKA1H331MPD1TD, UVY1H331MPD1TD, and EEU-HD1H331B provide 2000 Hrs @ 105°C lifetime, matching the UVZ1H331MPD1TD specification. EKMG500ETD331MJ16S provides 1000 Hrs @ 105°C, representing a reduced lifetime rating.

Compliance and Certifications: All parts are ROHS3 Compliant and REACH Unaffected, meeting regulatory requirements for the main part.

Ripple Current Performance: UVY1H331MPD1TD, EKMG500ETD331MJ16S, and EEU-HD1H331B provide enhanced ripple current capability at higher frequencies (615 mA @ 10 kHz or 100 kHz), offering improved performance margin in high-frequency applications.

Frequently Asked Questions (FAQ)

Q: Can I use EKMG500ETD331MJ16S as a direct replacement for UVZ1H331MPD1TD?

A: Yes, EKMG500ETD331MJ16S meets all core electrical and mechanical parameters. However, it provides 1000 Hrs @ 105°C lifetime versus 2000 Hrs for the original part. For applications requiring extended thermal life, UKA1H331MPD1TD, UVY1H331MPD1TD, or EEU-HD1H331B are preferred.

Q: Are there differences in ripple current handling between these parts?

A: The main part specifies 410 mA @ 120 Hz. UVY1H331MPD1TD, EKMG500ETD331MJ16S, and EEU-HD1H331B provide additional ripple current capacity at higher frequencies (615 mA @ 10 kHz or 100 kHz). This does not affect substitution but indicates enhanced performance capability in switching applications.

Q: Do all substitute parts fit the same PCB footprint?

A: Yes. All parts share identical mechanical specifications: 0.197" (5.00 mm) lead spacing, 0.394" (10.00 mm) diameter, and 0.689" (17.50 mm) seated height. Through-hole mounting configuration is consistent across all parts.

Q: Which substitute part should I choose for new designs?

A: EKMG500ETD331MJ16S and EEU-HD1H331B carry Active product status and are suitable for new designs. Both meet all electrical and mechanical requirements of the UVZ1H331MPD1TD.

Q: Are all parts RoHS compliant?

A: Yes. All listed parts are ROHS3 Compliant and REACH Unaffected, meeting environmental and regulatory standards.

Q: What is the difference between Nichicon UVZ, UKA, and UVY series?

A: All three Nichicon series meet the specified electrical parameters for this substitution. Series designation reflects internal product line organization. UVZ is the original part series; UKA and UVY are alternative Nichicon series with equivalent performance characteristics.
