EKZM350ETD331MJC5S Equivalent & Substitute Parts

Part Overview

The EKZM350ETD331MJC5S is a 330 µF, 35 V aluminum electrolytic capacitor manufactured by Chemi-Con in the KZM series. This radial, through-hole component is rated for 10,000 hours at 105°C and is designed for general-purpose applications. The part is currently active in production and available in Tape & Box packaging. Substitute parts are identified when equivalent electrical and mechanical parameters are required for component replacement, inventory management, or supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the EKZM350ETD331MJC5S are identified based on strict equivalence across the following critical parameters:

• Capacitance Value: 330 µF (exact match required)
• Voltage Rating: 35 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime Rating: 10,000 Hrs @ 105°C (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (exact match required)
• Polarization: Polar (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• Lead Spacing: 0.197" (5.00mm) (exact match required)
• Physical Dimensions: 0.394" Dia (10.00mm) and 0.551" (14.00mm) height (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

Substitute parts must satisfy all parameters listed above to ensure direct interchangeability in circuit applications without modification to PCB layout, schematic design, or assembly procedures.

Parameter Comparison

Engineering Selection Recommendations

Both the EKZM350ETD331MJC5S (Chemi-Con KZM series) and the 35ZLH330MEFCT810X12.5 (Rubycon ZLH series) are active production components with full ROHS3 compliance and REACH unaffected status. These parts are electrically and mechanically equivalent across all specified parameters, including capacitance, voltage rating, tolerance, lifetime rating, operating temperature range, physical dimensions, and lead spacing.

Selection between these two parts may be based on:

• Inventory Availability: The Rubycon substitute (35ZLH330MEFCT810X12.5) has significantly higher stock availability (203,963 pcs) compared to the Chemi-Con original (831 pcs).
• Packaging Format: The original part is supplied in Tape & Box (TB) packaging, while the substitute is supplied in Cut Tape (CT) packaging.
• Supply Chain Requirements: Either part satisfies identical electrical and mechanical requirements for direct substitution in through-hole PCB applications.

Both parts are suitable for general-purpose applications requiring 330 µF capacitance at 35 V with 10,000-hour lifetime at 105°C.

Frequently Asked Questions (FAQ)

Q: Can the 35ZLH330MEFCT810X12.5 (Rubycon) be used as a direct replacement for the EKZM350ETD331MJC5S (Chemi-Con)?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical capacitance (330 µF), voltage rating (35 V), tolerance (±20%), lifetime rating (10,000 Hrs @ 105°C), operating temperature range (-40°C ~ 105°C), physical dimensions (0.394" Dia × 0.551" height), lead spacing (0.197"), and compliance certifications (ROHS3, REACH unaffected). No PCB layout or schematic modifications are required.

Q: What is the difference in ripple current between these two parts?

A: The Rubycon 35ZLH330MEFCT810X12.5 has a ripple current rating of 731.5 mA @ 120 Hz, compared to 665 mA @ 120 Hz for the Chemi-Con EKZM350ETD331MJC5S. Both parts have identical ripple current ratings at 100 kHz (1.33 A). The higher low-frequency ripple current of the Rubycon part does not affect substitution compatibility.

Q: Are there packaging differences between these parts?

A: Yes. The Chemi-Con EKZM350ETD331MJC5S is supplied in Tape & Box (TB) packaging, while the Rubycon 35ZLH330MEFCT810X12.5 is supplied in Cut Tape (CT) packaging. Both packaging formats are suitable for through-hole assembly processes. Packaging selection depends on production line requirements and handling procedures.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the EKZM350ETD331MJC5S and 35ZLH330MEFCT810X12.5 are ROHS3 compliant and REACH unaffected. Both parts are classified under ECCN EAR99 and HTSUS 8532.22.0020.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by exact equivalence across capacitance value, voltage rating, tolerance, lifetime rating, operating temperature range, polarization type, mounting type, package style, lead spacing, physical dimensions, and compliance certifications. Any deviation in these parameters disqualifies a part from direct substitution.
