UEP1E331MHD1CV Equivalent & Substitute Parts

Part Overview

The UEP1E331MHD1CV is a 330 µF, 25 V aluminum electrolytic capacitor manufactured by Nichicon in a radial, can package. This component is rated for 1000 hours at 105°C and is designed for general-purpose applications requiring through-hole mounting. The part is currently active in production. Substitute parts are necessary when the primary part number becomes unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits selection from qualified equivalent components within the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the UEP1E331MHD1CV is determined by strict equivalence across the following critical parameters:

• Capacitance value: 330 µF (exact match required)
• Rated voltage: 25 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime rating: 1000 Hrs @ 105°C (exact match required)
• Operating temperature range: -55°C ~ 105°C (exact match required)
• Polarization: Bi-Polar (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Radial, Can (exact match required)
• Physical dimensions: 0.492" Dia (12.50mm), 0.866" Height (22.00mm), 5.00mm lead spacing (exact match required)
• Ripple current ratings: 320 mA @ 120 Hz and 480 mA @ 10 kHz (exact match required)

The substitute part UEP1E331MHD meets all these criteria and is therefore a direct parametric equivalent.

Engineering Selection Recommendations

The UEP1E331MHD1CV is the recommended primary selection for new designs due to its active product status. The substitute part UEP1E331MHD is electrically and mechanically identical across all specified parameters and is suitable for replacement applications where the primary part is unavailable. However, UEP1E331MHD carries a "Not For New Designs" status, indicating it is in mature or end-of-life phase. For new design implementations, UEP1E331MHD1CV should be specified. For existing designs or legacy system maintenance where UEP1E331MHD1CV supply is constrained, UEP1E331MHD provides full functional equivalence with identical electrical performance and physical compatibility.

Frequently Asked Questions (FAQ)

Q: Can UEP1E331MHD be used as a direct replacement for UEP1E331MHD1CV?

A: Yes. Both parts are identical in capacitance (330 µF), rated voltage (25 V), tolerance (±20%), lifetime rating (1000 Hrs @ 105°C), operating temperature range (-55°C ~ 105°C), polarization (Bi-Polar), ripple current specifications (320 mA @ 120 Hz, 480 mA @ 10 kHz), and physical dimensions (0.492" Dia, 0.866" Height, 5.00mm lead spacing). They are parametric equivalents suitable for direct substitution in through-hole applications.

Q: Why is UEP1E331MHD marked "Not For New Designs"?

A: This designation indicates the part is in a mature or declining production phase. For new product development, UEP1E331MHD1CV should be specified to ensure long-term availability and supply chain stability.

Q: Are there any compliance or certification differences between these parts?

A: The provided data indicates both parts share the same HTSUS code (8532.22.0020). UEP1E331MHD includes RoHS3 compliance, REACH unaffected status, and EAR99 ECCN classification. Compliance documentation for UEP1E331MHD1CV should be verified with the manufacturer if required for your application.

Q: What is the physical footprint compatibility?

A: Both parts are radial, can-type capacitors with identical dimensions: 0.492" diameter, 0.866" maximum seated height, and 5.00mm lead spacing. They are mechanically interchangeable in through-hole PCB designs without layout modifications.

Q: Can these parts be used interchangeably in high-ripple-current applications?

A: Yes. Both parts are rated for identical ripple current specifications: 320 mA at 120 Hz and 480 mA at 10 kHz. They are suitable for applications requiring these ripple current levels.
