Substitute Part Grouping Explanation

Substitution eligibility for the EKZM350ELL331MJC5S is determined by strict equivalence across the following parameters:

Capacitance: 330 µF (exact match required)
Voltage Rating: 35 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime: 10,000 Hrs @ 105°C (exact match required)
Operating Temperature: -40°C ~ 105°C (exact match required)
Polarization: Polar (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required)
Case Diameter: 0.394" (10.00 mm) (exact match required)
Height: 0.551" (14.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)

All four substitute parts meet these criteria. Variations in ripple current ratings, impedance, and series resistance do not disqualify substitution when all primary electrical and mechanical parameters are identical.

Engineering Selection Recommendations

All four substitute parts are active products from Rubycon, a qualified manufacturer in the aluminum electrolytic capacitor category. The substitute parts 35ZLH330MEFC10X12.5 and 35ZLH330MEFCCC10X12.5 demonstrate identical impedance (39 mOhms) and ripple current performance at 100 kHz (1.33 A) to the original EKZM350ELL331MJC5S, making them direct functional equivalents. The 35ZLJ330M10X12.5 offers higher ripple current capability at both frequency points, while the 35YXJ330M10X12.5 provides lower ripple current performance. All substitute parts carry ROHS3 compliance certification and are suitable for direct replacement in applications where the original part is specified.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the EKZM350ELL331MJC5S?

A: Yes. All four substitute parts meet the core electrical and mechanical specifications: 330 µF capacitance, 35 V voltage rating, ±20% tolerance, 10,000-hour lifetime at 105°C, identical physical dimensions (10.00 mm diameter, 14.00 mm height, 5.00 mm lead spacing), and through-hole radial mounting. They are direct substitutes for general-purpose applications.

Q: What is the difference between the substitute parts?

A: The substitute parts differ in ripple current ratings and impedance. The 35ZLH330MEFC10X12.5 and 35ZLH330MEFCCC10X12.5 match the original part's impedance and high-frequency ripple current. The 35ZLJ330M10X12.5 offers higher ripple current capability. The 35YXJ330M10X12.5 has lower ripple current performance. These differences do not affect substitution eligibility when all primary parameters are identical.

Q: Are there any compliance or certification differences?

A: The substitute parts are ROHS3 compliant. The original EKZM350ELL331MJC5S does not specify RoHS status in the provided data. All parts carry the same ECCN (EAR99) and HTSUS (8532.22.0020) classifications.

Q: Will these parts fit my PCB layout?

A: Yes. All substitute parts have identical lead spacing (0.197" / 5.00 mm), case diameter (0.394" / 10.00 mm), and maximum seated height (0.551" / 14.00 mm). They are direct mechanical replacements requiring no PCB layout modifications.

Q: Which substitute part should I choose?

A: Selection depends on application requirements. For applications requiring impedance and ripple current matching the original part, use 35ZLH330MEFC10X12.5 or 35ZLH330MEFCCC10X12.5. For applications requiring higher ripple current capability, use 35ZLJ330M10X12.5. For cost-optimized applications with lower ripple current requirements, use 35YXJ330M10X12.5.
