UVZ1J331MPD1TD Equivalent & Substitute Parts

Part Overview

The UVZ1J331MPD1TD is a 330 µF, 63 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 This component is classified as Not For New Designs, indicating it has been superseded in Nichicon's product line. The part is rated for 2000 hours at 105°C and is suitable for general-purpose applications requiring through-hole mounting with radial lead spacing of 5.00 mm.

Finding equivalent and substitute parts is necessary due to the product's discontinued status for new designs and potential supply constraints. Equivalent alternatives maintain identical electrical and mechanical specifications while offering improved availability or active product status.

Substitute Part Grouping Explanation

Substitution eligibility for the UVZ1J331MPD1TD is determined by strict equivalence across the following critical parameters:

Capacitance value: 330 µF (exact match required)
Voltage rating: 63 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime rating: 2000 Hrs @ 105°C (exact match required)
Operating temperature range: -55°C ~ 105°C (exact match required)
Lead spacing: 5.00 mm (exact match required)
Case diameter: 10.00 mm (exact match required)
Height: 22.00 mm maximum (exact match required)
Mounting type: Through Hole, Radial configuration (exact match required)
Polarization: Polar (exact match required)

All identified substitute parts meet these criteria without exception. Substitutes are grouped by manufacturer and product status to facilitate selection based on availability and design phase requirements.

Engineering Selection Recommendations

For new design implementations, ECA-1JHG331B (Panasonic) is the preferred selection. This part maintains full electrical and mechanical equivalence to UVZ1J331MPD1TD while carrying Active product status, ensuring long-term availability and manufacturer support. The part is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

For existing designs or legacy system maintenance where Nichicon parts are specified, UVY1J331MPD1TD provides direct equivalence within the same manufacturer's portfolio. Both Nichicon alternatives are ROHS3 compliant and REACH unaffected.

All three parts are suitable for through-hole PCB assembly with identical lead spacing and case dimensions. Selection between alternatives should be based on supply chain availability, cost considerations, and design phase requirements rather than electrical performance, as all parts are electrically and mechanically equivalent.

Frequently Asked Questions (FAQ)

Q: Can ECA-1JHG331B replace UVZ1J331MPD1TD directly on a PCB?

A: Yes. Both parts are radial aluminum electrolytic capacitors with identical lead spacing (5.00 mm), case diameter (10.00 mm), and height (22.00 mm). No PCB layout modifications are required.

Q: What is the difference between UVZ1J331MPD1TD and UVY1J331MPD1TD?

A: Both are Nichicon 330 µF, 63 V radial capacitors with identical electrical specifications and physical dimensions. The primary difference is series designation (UVZ versus UVY). Both are classified as Not For New Designs.

Q: Why is ECA-1JHG331B recommended over the Nichicon alternatives?

A: ECA-1JHG331B carries Active product status, indicating ongoing manufacturer support and supply availability. The Nichicon parts (UVZ and UVY series) are Not For New Designs, meaning they are superseded products with limited future availability.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. UVZ1J331MPD1TD, UVY1J331MPD1TD, and ECA-1JHG331B are all ROHS3 compliant and REACH unaffected.

Q: Can these parts be used interchangeably in legacy equipment?

A: Yes. All three parts meet identical electrical and mechanical specifications. Interchangeability is guaranteed for applications requiring 330 µF, 63 V radial aluminum electrolytic capacitors with 5.00 mm lead spacing and through-hole mounting.

Q: What is the ripple current rating difference between 120 Hz and 10 kHz?

A: All three parts are rated for 510 mA ripple current at 120 Hz and 765 mA at 10 kHz. This difference reflects the frequency-dependent behavior of aluminum electrolytic capacitors and does not affect substitution eligibility.
