UKT1E331MPD1TA Equivalent & Substitute Parts

Part Overview

The UKT1E331MPD1TA 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 This component is classified as "Not For New Designs," indicating it has been superseded in the product lifecycle. The UKT series offers a 1000-hour lifetime rating at 105°C and is suitable for audio applications requiring through-hole mounting.

Finding equivalent or substitute parts becomes necessary when the original UKT1E331MPD1TA reaches end-of-life status, inventory depletion, or when design requirements demand improved performance characteristics such as extended operational lifetime or enhanced ripple current handling.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UKT1E331MPD1TA is determined by strict equivalence across the following parameters:

• Electrical Parameters: Capacitance (330 µF), voltage rating (25 V), and tolerance (±20%) must match exactly
• Physical Parameters: Lead spacing (4.60 mm), case diameter (8.00 mm), and height (13.00 mm) must be identical to ensure PCB compatibility
• Mounting Configuration: Through-hole radial mounting is required
• Environmental Compliance: RoHS3 compliance is mandatory

Substitute parts may differ in:

• Manufacturer (Nichicon or Chemi-Con)
• Series designation (UKT, UKA, UPA, UVY, or KMG)
• Lifetime rating at 105°C (1000 Hrs, 2000 Hrs, or 3000 Hrs)
• Ripple current specifications
• Product status (Active or Not For New Designs)
• Packaging format (Cut Tape or Tape & Box)

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: UPA1E331MPD1TA

This part maintains full electrical and mechanical compatibility with the UKT1E331MPD1TA while offering superior operational characteristics. The UPA series is classified as Active, ensuring continued availability and support. The extended 3000-hour lifetime at 105°C provides enhanced reliability for long-term applications. RoHS3 compliance and REACH affected status align with current regulatory requirements.

Secondary Recommendation: EKMG250ETD331MHB5D

This Chemi-Con alternative provides equivalent electrical and mechanical specifications with Active product status. The KMG series delivers robust performance with 1000-hour lifetime rating at 105°C. RoHS3 compliance is confirmed. Packaging is supplied in Tape & Box format, suitable for higher-volume procurement scenarios.

Equivalent Alternative: UKA1E331MPD1TD

This Nichicon part offers intermediate performance with a 2000-hour lifetime at 105°C, positioned between the original UKT series and the premium UPA series. While classified as Not For New Designs, it provides a direct upgrade path with extended operational life.

Compatibility Note: UVY1E331MPD1TD

This part matches the original UKT1E331MPD1TA in lifetime rating (1000 Hrs @ 105°C) and is electrically and mechanically identical. However, it is also classified as Not For New Designs, making it suitable only for legacy system maintenance or direct replacement scenarios.

Frequently Asked Questions (FAQ)

Q: Can I use UPA1E331MPD1TA as a direct replacement for UKT1E331MPD1TA?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (25 V), tolerance (±20%), lead spacing (4.60 mm), case diameter (8.00 mm), and height (13.00 mm). The UPA series is mechanically and electrically compatible with through-hole PCB layouts designed for the UKT series.

Q: What is the difference between the Nichicon and Chemi-Con options?

A: Both manufacturers provide equivalent electrical performance and mechanical dimensions. The primary differences are manufacturer identity and packaging format. Nichicon parts are supplied in Cut Tape, while the Chemi-Con EKMG250ETD331MHB5D is supplied in Tape & Box format. Selection depends on procurement preferences and inventory management requirements.

Q: Why should I choose UPA1E331MPD1TA over UKA1E331MPD1TD?

A: The UPA1E331MPD1TA offers a 3000-hour lifetime at 105°C compared to the UKA's 2000-hour rating, providing extended operational reliability. Additionally, the UPA series is classified as Active, ensuring long-term availability and manufacturing support, whereas the UKA is Not For New Designs.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance certification, meeting current environmental and regulatory standards.

Q: Can I mix different substitute parts in the same design?

A: Yes. All substitute parts are electrically and mechanically equivalent, allowing interchangeability within the same PCB layout. However, maintaining consistency within a production batch is recommended for quality control purposes.

Q: What does "Not For New Designs" mean?

A: This designation indicates the part has been superseded in the manufacturer's product line. While existing inventory may be available, the manufacturer does not recommend using these parts for new product development. Parts classified as Active, such as UPA1E331MPD1TA and EKMG250ETD331MHB5D, are preferred for new designs.

Q: Does packaging format affect electrical performance?

A: No. Cut Tape and Tape & Box packaging formats do not affect electrical or mechanical performance. The difference is purely logistical, relating to how components are supplied and handled during procurement and assembly.
