Engineering Selection Recommendations

For New Designs: The UVY1H331MHD4 (Nichicon, Active status) and 50PX330MEFC10X16 (Rubycon, Active status) are the recommended selections for new circuit designs. Both parts carry Active product status and are supported for ongoing production and supply.

For Existing Designs Requiring Substitution: The UVY1H331MPD (Nichicon, UVY series) and UVZ1H331MPD (Nichicon, UVZ series) are parametric equivalents with identical electrical and mechanical specifications. These parts are marked as "Not For New Designs" but remain suitable for replacement in existing applications where the original part becomes unavailable.

The UKA1H331MPD (Nichicon, UKA series) is also a parametric equivalent but is designated "Not For New Designs" and should be used only when no other alternatives are available.

Cross-Manufacturer Substitution: The EEU-HD1H331 (Panasonic Electronic Components, HD series) provides an alternative from a different manufacturer while maintaining identical electrical and mechanical parameters. This part carries Active status and is suitable for both new designs and replacement applications.

All listed substitutes are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can UVY1H331MHD4 be directly replaced with UVY1H331MPD?

A: Yes. Both parts are from the Nichicon UVY series with identical capacitance (330 µF), voltage rating (50 V), tolerance (±20%), lifetime (2000 Hrs @ 105°C), operating temperature range (-55°C ~ 105°C), and mechanical dimensions (0.197" lead spacing, 0.394" diameter, 0.689" height). Direct substitution is electrically and mechanically compatible.

Q: What is the difference between UVY1H331MHD4 and UVZ1H331MPD?

A: Both parts are Nichicon aluminum electrolytic capacitors with identical electrical specifications (330 µF, 50 V, ±20%, 2000 Hrs @ 105°C) and mechanical dimensions. The primary difference is the series designation (UVY versus UVZ). Both are parametric equivalents suitable for direct replacement.

Q: Can I use the Rubycon 50PX330MEFC10X16 as a substitute?

A: Yes. The Rubycon 50PX330MEFC10X16 meets all critical electrical parameters (330 µF, 50 V, ±20%, 2000 Hrs @ 105°C) and mechanical specifications (0.197" lead spacing, 0.394" diameter, 0.689" height). It is an active product from an alternative manufacturer and is suitable for direct replacement.

Q: Is the Panasonic EEU-HD1H331 compatible with the UVY1H331MHD4?

A: Yes. The Panasonic EEU-HD1H331 is a parametric equivalent with matching capacitance (330 µF), voltage (50 V), tolerance (±20%), lifetime (2000 Hrs @ 105°C), and package dimensions. It is an active product and provides cross-manufacturer compatibility.

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

A: Parts marked "Not For New Designs" are legacy or transitional products that remain available for replacement in existing applications but are not recommended for incorporation into new circuit designs. For new designs, select parts with Active product status such as UVY1H331MHD4, 50PX330MEFC10X16, or EEU-HD1H331.

Q: Are all listed substitutes RoHS compliant?

A: Yes. All substitute parts listed are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the significance of lead spacing and package dimensions in substitution?

A: Lead spacing (0.197" / 5.00 mm) and package dimensions (0.394" diameter, 0.689" height) determine physical compatibility with printed circuit board layouts and component placement. All listed substitutes maintain identical dimensions, ensuring direct mechanical compatibility without PCB redesign.

Q: Can ripple current differences affect substitution suitability?

A: Ripple current specifications are provided for reference but do not disqualify substitution. All listed parts meet the minimum ripple current requirements at both low frequency (120 Hz) and high frequency (10 kHz or 100 kHz). The UVY1H331MHD4 and most substitutes specify 410 mA @ 120 Hz and 615 mA @ 10 kHz, with the Rubycon part specifying 470 mA @ 120 Hz, which is within acceptable operating parameters.
