UHE1V331MPD1TD Equivalent & Substitute Parts

Part Overview

The UHE1V331MPD1TD is a 330 µF, 35 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 This component is classified as Not For New Designs, indicating it has been superseded in Nichicon's product line. Finding equivalent and substitute parts is necessary for ongoing maintenance, repair, and legacy system support where this specific part number may no longer be readily available or where design flexibility permits component substitution.

Substitute Part Grouping Explanation

Substitution of the UHE1V331MPD1TD is determined by strict electrical and mechanical compatibility. All substitute parts must meet the following core criteria:

Capacitance: 330 µF (exact match required)
Voltage Rating: 35 V (minimum, equal or higher acceptable)
Tolerance: ±20% (electrical tolerance band)
Package Type: Radial, Can (mechanical form factor)
Lead Spacing: 0.197" (5.00 mm) (PCB footprint compatibility)
Size / Diameter: 0.394" (10.00 mm) (board space constraint)
Height (Seated Max): 0.689" (17.50 mm) (clearance requirement)
Mounting Type: Through Hole (assembly method)
Operating Temperature: -40°C to 105°C (environmental compatibility)
Polarization: Polar (electrical requirement)

All identified substitute parts meet these parameters. Differences in ripple current ratings, impedance, and lifetime specifications do not prevent substitution but may affect performance characteristics in specific applications.

Engineering Selection Recommendations

When selecting a substitute for UHE1V331MPD1TD, consider the following factors based on product status and compliance:

Active Product Status Priority: EEU-EB1V331B (Panasonic), 860040575009 (Würth Elektronik), and EKY-350ETD331MJ16S (Chemi-Con) carry Active product status, indicating ongoing manufacturer support and availability. These are preferred for new applications and long-term supply chain stability.

Compliance Alignment: All substitute parts maintain ROHS3 compliance, matching the original part's regulatory standing. All parts are EAR99 classified and carry identical HTSUS codes (8532.22.0020), confirming equivalent trade and export status.

Mechanical Fit: EEU-EB1V331B has a slightly reduced seated height of 0.669" (17.00 mm) compared to the original 0.689" (17.50 mm). This difference may provide additional clearance in space-constrained applications but does not prevent substitution. All other dimensional parameters are identical across all parts.

Lifetime Consideration: EEU-EB1V331B offers extended lifetime of 10000 hours at 105°C, compared to 7000 hours for the original and other substitutes. This extended rating may provide improved reliability in continuous-duty applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute EEU-EB1V331B directly into a circuit designed for UHE1V331MPD1TD?

A: Yes. Both parts share identical electrical specifications (330 µF, 35 V, ±20% tolerance), identical lead spacing (5.00 mm), identical diameter (10.00 mm), and compatible heights. The EEU-EB1V331B is 0.020" shorter, which does not prevent direct substitution on standard PCB layouts.

Q: What is the difference between "Not For New Designs" and "Active" product status?

A: "Not For New Designs" indicates the manufacturer has discontinued active development and recommends against using the part in new circuit designs, though existing inventory may remain available. "Active" status indicates the manufacturer continues to produce and support the part. For legacy system repairs, either status is acceptable; for new designs, Active status parts are preferred.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status, matching the original UHE1V331MPD1TD. This ensures equivalent environmental and regulatory compliance.

Q: Does the difference in ripple current ratings affect substitution?

A: Ripple current ratings reflect the part's ability to handle AC current superimposed on DC voltage. Differences in ripple current do not prevent substitution but may affect thermal performance in high-ripple-current applications. Selection should be based on circuit requirements and thermal management design.

Q: What is the significance of the different packaging types (Cut Tape vs. Tape & Box)?

A: Packaging type affects handling and storage but does not impact electrical or mechanical compatibility. Cut Tape (CT) is suitable for individual component selection; Tape & Box (TB) is typical for higher-volume orders. Both formats contain identical components.

Q: Can I use a 50 V rated capacitor instead of 35 V?

A: While higher voltage ratings are electrically compatible, they are not listed as substitutes in this reference. Substitution must be limited to parts meeting the specified parameters. If higher voltage rating is required, consult the original design documentation or contact the equipment manufacturer.
