UHV1E331MPD1TD Equivalent & Substitute Parts

Part Overview

The UHV1E331MPD1TD is a 330 µF, 25 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 This component is classified as Not For New Designs, indicating it has been superseded in the manufacturer's product line. Finding equivalent substitute parts is necessary for maintenance, repair, and legacy system support where original components are unavailable or inventory is depleted.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UHV1E331MPD1TD is determined by strict equivalence across the following parameters:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 25 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime specification: 6000 Hrs @ 105°C (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)
• Physical form factor: Radial, Can package with 0.138" (4.60mm) lead spacing
• Case dimensions: 0.315" Dia (8.00mm) and 0.512" (13.00mm) height
• Mounting configuration: Through Hole

The EKZH250ETD331MHB5D from Chemi-Con meets all these criteria and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The EKZH250ETD331MHB5D qualifies as a direct parametric equivalent to the UHV1E331MPD1TD based on matching electrical specifications, physical dimensions, and compliance certifications. Both components are ROHS3 compliant and share identical ECCN and HTSUS classifications.

The primary distinction is product status: the UHV1E331MPD1TD is Not For New Designs, while the EKZH250ETD331MHB5D is Active. For applications requiring component replacement or new procurement, the Chemi-Con part is the appropriate selection.

Minor variations in ripple current ratings (495 mA vs. 450 mA @ 120 Hz; 990 mA vs. 900 mA @ 100 kHz) and impedance (59 mOhms vs. 62 mOhms) are within acceptable tolerance for general-purpose aluminum electrolytic capacitor applications and do not disqualify substitution.

Frequently Asked Questions (FAQ)

Q: Can the EKZH250ETD331MHB5D be used as a direct replacement for the UHV1E331MPD1TD?

A: Yes. Both components share identical capacitance (330 µF), voltage rating (25 V), tolerance (±20%), lifetime specification (6000 Hrs @ 105°C), operating temperature range (-40°C ~ 105°C), and physical dimensions. They are mechanically and electrically interchangeable in through-hole applications.

Q: What are the differences between these two parts?

A: The primary differences are manufacturer (Nichicon vs. Chemi-Con), product status (Not For New Designs vs. Active), and minor performance variations in ripple current and impedance. The Chemi-Con part has slightly lower ripple current ratings and marginally higher impedance, but these differences do not affect compatibility in standard applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the UHV1E331MPD1TD and EKZH250ETD331MHB5D are ROHS3 compliant.

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

A: This designation indicates the UHV1E331MPD1TD has been superseded by the manufacturer and is no longer recommended for new product development. For legacy system support and repair, the active equivalent EKZH250ETD331MHB5D is the appropriate choice.

Q: Are the lead spacings identical?

A: Yes. Both components have 0.138" (4.60mm) lead spacing and are compatible with the same PCB footprints designed for radial through-hole capacitors.
