Equivalent & Substitute Parts for UES1H331MHM

Part Overview

The UES1H331MHM is a 330 µF, 50 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 1000 hours at 85°C and is designed for audio applications. The part carries a "Not For New Designs" product status, indicating it has been superseded in Nichicon's product line. Finding equivalent or substitute parts is necessary for ongoing maintenance, repair, and legacy system support where this specific component is required or where design flexibility permits upgraded alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the UES1H331MHM is determined by the following critical parameters:

• Capacitance Value: Must be 330 µF (exact match required)
• Voltage Rating: Must be equal to or greater than 50 V
• Tolerance: ±20% (standard for this capacitor class)
• Package / Case: Radial, Can format with matching lead spacing (0.295" / 7.50 mm)
• Mounting Type: Through Hole
• Polarization: Bi-Polar

The substitute parts listed below meet these core electrical and mechanical compatibility criteria. Both UEP1J331MHD and UVP1J331MHD provide higher voltage ratings (63 V) and improved thermal performance compared to the original part, making them suitable direct replacements in applications where the UES1H331MHM is no longer available.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are manufactured by Nichicon and maintain full compatibility with the UES1H331MHM in terms of electrical function and physical form factor. Selection between the two substitutes depends on application requirements:

UEP1J331MHD provides an extended operating temperature range (-55°C to 105°C) and rated lifetime of 1000 hours at 105°C, making it suitable for applications requiring broader temperature tolerance.

UVP1J331MHD offers doubled lifetime performance (2000 hours at 85°C) within the same operating temperature range as the original part (-40°C to 85°C), providing enhanced reliability for standard temperature environments.

Both parts carry ROHS3 compliance and are suitable for direct substitution in legacy audio and general-purpose applications. The marginal increase in seated height (0.319" versus 0.299") is negligible for through-hole PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can UEP1J331MHD or UVP1J331MHD be used as direct replacements for UES1H331MHM?

A: Yes. Both substitute parts match the critical parameters: 330 µF capacitance, ±20% tolerance, radial can package with 0.295" lead spacing, and through-hole mounting. The higher voltage ratings (63 V versus 50 V) and improved thermal performance represent upgrades rather than compromises.

Q: What is the difference between the two substitute parts?

A: UEP1J331MHD extends the operating temperature range to -55°C ~ 105°C with 1000-hour lifetime at 105°C. UVP1J331MHD maintains the original temperature range (-40°C ~ 85°C) but doubles the lifetime to 2000 hours at 85°C. Choose based on thermal environment requirements.

Q: Will the slightly taller height (34.60 mm versus 33.00 mm) cause PCB layout issues?

A: The 0.50 mm height difference is within standard PCB design tolerances for through-hole components and should not cause clearance or assembly issues in typical applications.

Q: Are both substitutes RoHS compliant?

A: Yes. Both UEP1J331MHD and UVP1J331MHD are ROHS3 compliant, matching the compliance status of the original UES1H331MHM.

Q: Why is the original part marked "Not For New Designs"?

A: This designation indicates the UES1H331MHM has been superseded in Nichicon's current product portfolio. The substitute parts represent current-generation alternatives with equivalent or superior performance characteristics.
