EKZE250ETD331MJC5S Equivalent & Substitute Parts

Part Overview

The EKZE250ETD331MJC5S is a 330 µF, 25 V aluminum electrolytic capacitor manufactured by Chemi-Con in the KZE series. This radial, through-hole component is designed for general-purpose applications requiring 4000 hours of operational life at 105°C. The part is currently active in production status.

Substitute parts are necessary when the primary manufacturer part becomes unavailable, when supply chain constraints require alternative sourcing, or when design flexibility permits equivalent components from qualified manufacturers. Equivalent substitutes must maintain identical electrical ratings and mechanical compatibility to ensure proper circuit performance without redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EKZE250ETD331MJC5S is determined by strict equivalence across the following parameters:

Critical Electrical Parameters:

• Capacitance: 330 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 25 V (exact match required)
• Lifetime: 4000 Hrs @ 105°C (exact match required)
• Operating Temperature Range: -40°C to 105°C (exact match required)

Critical Mechanical Parameters:

• Lead Spacing: 0.197" (5.00 mm) (exact match required)
• Case Diameter: 0.394" (10.00 mm) (exact match required)
• Maximum Seated Height: 0.551" (14.00 mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Type: Radial, Can (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Polarization: Polar (exact match required)

All three substitute parts listed meet these criteria and are therefore classified as parametric equivalents suitable for direct replacement in the same circuit application.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: EEU-FM1E331B (Panasonic Electronic Components)

The EEU-FM1E331B is the preferred substitute for new designs and ongoing production. This part maintains active product status and full ROHS3 compliance. All electrical and mechanical parameters are identical to the EKZE250ETD331MJC5S. Current inventory availability is 8009 units.

Secondary Recommendation: REA1013331M025K (KYOCERA AVX)

The REA1013331M025K is a qualified alternative with active product status and ROHS3 compliance. All critical parameters match the primary part. Current inventory availability is 1558 units. Moisture Sensitivity Level is rated at 1 (Unlimited).

Tertiary Option: UHD1E331MPD6TD (Nichicon)

The UHD1E331MPD6TD meets all parametric equivalence requirements and maintains ROHS3 compliance. However, this part carries a "Not For New Designs" product status designation, indicating it is in mature or declining production phase. Current inventory availability is 2282 units. REACH Status is listed as Affected, requiring additional compliance verification for specific end-use applications.

Frequently Asked Questions (FAQ)

Q: Can the EEU-FM1E331B be used as a direct replacement for the EKZE250ETD331MJC5S?

A: Yes. The EEU-FM1E331B is a parametric equivalent with identical capacitance (330 µF), voltage rating (25 V), tolerance (±20%), lifetime (4000 Hrs @ 105°C), and mechanical dimensions. Both parts are through-hole radial cans with 5.00 mm lead spacing and 10.00 mm diameter. No circuit redesign is required.

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

A: All three substitutes meet the electrical and mechanical specifications of the EKZE250ETD331MJC5S. The primary differences are: (1) Product Status—EEU-FM1E331B and REA1013331M025K are Active; UHD1E331MPD6TD is Not For New Designs; (2) Inventory levels vary; (3) UHD1E331MPD6TD has REACH Status listed as Affected, requiring additional compliance review.

Q: Are there any ripple current differences between the main part and substitutes?

A: Ripple current specifications vary among the parts. The EKZE250ETD331MJC5S specifies 515 mA @ 120 Hz and 1.03 A @ 100 kHz. The EEU-FM1E331B specifies 903 mA @ 120 Hz and 1.29 A @ 100 kHz. The REA1013331M025K specifies 350 mA @ 120 Hz and 490 mA @ 10 kHz. The UHD1E331MPD6TD specifies 42.5 mA @ 120 Hz and 85 mA @ 100 kHz. Circuit designers must verify that the selected substitute meets the ripple current requirements of the specific application.

Q: Can I use the UHD1E331MPD6TD in a new product design?

A: The UHD1E331MPD6TD carries a "Not For New Designs" product status. This designation indicates the part is in mature production phase and may have limited long-term availability. For new designs, EEU-FM1E331B or REA1013331M025K are recommended.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All three substitute parts—EEU-FM1E331B, REA1013331M025K, and UHD1E331MPD6TD—are ROHS3 Compliant, matching the compliance status of the EKZE250ETD331MJC5S.

Q: Do the mechanical dimensions match exactly across all parts?

A: Yes. All parts share identical mechanical specifications: 0.394" (10.00 mm) diameter, 0.551" (14.00 mm) maximum seated height, and 0.197" (5.00 mm) lead spacing. All are through-hole radial can packages suitable for the same PCB footprint.
