UPB1E331MPD1TD Equivalent & Substitute Parts

Part Overview

The UPB1E331MPD1TD is a 330 µF, 25 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, making direct sourcing increasingly difficult. Equivalent and substitute parts from active manufacturers provide functional alternatives for new procurement while maintaining electrical and mechanical compatibility with existing circuit designs.

Substitute Part Grouping Explanation

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

Capacitance: 330 µF (exact match required)
Voltage Rating: 25 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime: 7000 Hrs @ 105°C (exact match required)
Operating Temperature: -40°C ~ 105°C (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required)
Package Diameter: 0.394" Dia (10.00 mm) (exact match required)
Package Height: 0.551" (14.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Package / Case: Radial, Can (exact match required)

All substitute parts listed meet these criteria and are therefore direct functional equivalents suitable for PCB-level replacement without circuit redesign.

Engineering Selection Recommendations

For new designs and long-term procurement, select from parts with Active product status:

860040475006 (Würth Elektronik WCAP-ATUL series): Active status with highest ripple current ratings at both 120 Hz (619.5 mA) and 100 kHz (826 mA). ROHS3 compliant. Cut Tape packaging suitable for automated assembly.
EKY-250ETD331MJC5S (Chemi-Con KY series): Active status with high ripple current at 100 kHz (865 mA). ROHS3 compliant. Tape & Box packaging available.

For existing inventory management or legacy system support, parts with Last Time Buy or Not For New Designs status remain electrically equivalent but should not be selected for new production:

25YXH330MEFCT810X12.5 (Rubycon YXH series): Last Time Buy status. Ripple current 475.75 mA @ 120 Hz. ROHS3 compliant.
UHE1E331MPD6TD (Nichicon UHE series): Not For New Designs status. Highest ripple current among Nichicon alternatives at 605.5 mA @ 120 Hz and 865 mA @ 100 kHz.

All substitute parts maintain identical capacitance, voltage rating, tolerance, lifetime rating, operating temperature range, and physical dimensions as the original UPB1E331MPD1TD.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for UPB1E331MPD1TD?

A: Yes. All listed substitute parts are electrically and mechanically equivalent. They share identical capacitance (330 µF), voltage rating (25 V), tolerance (±20%), lifetime (7000 Hrs @ 105°C), operating temperature range (-40°C ~ 105°C), and physical dimensions (0.394" diameter, 0.551" height, 5.00 mm lead spacing). Through-hole mounting and radial can package are identical.

Q: What is the difference between the substitute parts?

A: Differences exist in ripple current handling, impedance, product lifecycle status, and packaging format. Ripple current ratings vary from 255 mA to 619.5 mA @ 120 Hz and 331.5 mA to 865 mA @ 100 kHz. Impedance ranges from 80 mOhms to 160 mOhms where specified. Product status ranges from Active (recommended for new designs) to Obsolete.

Q: Which substitute should I choose for a new design?

A: Select from parts with Active product status: 860040475006 (Würth Elektronik) or EKY-250ETD331MJC5S (Chemi-Con). Both offer long-term availability, ROHS3 compliance, and superior ripple current performance compared to the obsolete UPB1E331MPD1TD.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Cut Tape, Bulk, Tape & Box) affects supply chain logistics and assembly automation compatibility, not electrical characteristics. Select based on your procurement and manufacturing process requirements.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed carry ROHS3 Compliant certification. The original UPB1E331MPD1TD does not specify RoHS status due to its obsolete classification.

Q: What does "Last Time Buy" or "Not For New Designs" mean?

A: These designations indicate the manufacturer is discontinuing or has discontinued the product line. Parts with these statuses remain functionally equivalent but have limited future availability. For new production, select only Active status parts.
