Key Parameters

Substitute Part Grouping Explanation

Substitution of the KY35VB152M12X35LL is determined by strict adherence to the following core parameters:

Mandatory Matching Parameters:

• Capacitance: 1500 µF
• Voltage Rating: 35 V
• Tolerance: ±20%
• Polarization: Polar
• Mounting Type: Through Hole
• Package Type: Radial, Can
• Lead Spacing: 0.197" (5.00mm)
• Diameter: 0.492" (12.50mm)
• Lifetime: 10,000 Hrs @ 105°C
• Operating Temperature: -40°C ~ 105°C

Variable Parameters (Acceptable Differences):

• Height - Seated (Max): Variations permitted within physical envelope constraints
• Impedance: Variations permitted based on manufacturer design
• Ripple Current @ Low Frequency: Variations permitted; higher values indicate improved performance
• Ripple Current @ High Frequency: Variations permitted; higher values indicate improved performance
• RoHS Status: Upgrades from non-compliant to compliant are acceptable
• Manufacturer: Cross-manufacturer substitution permitted

All substitute parts listed maintain identical electrical specifications for capacitance, voltage, tolerance, and thermal characteristics. Physical height variations and performance enhancements in ripple current handling and impedance are acceptable within the constraints of through-hole radial can packaging.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Series, RoHS Upgrade): The EKY-350ELL152MK35S is the direct equivalent within the Chemi-Con KY series. It maintains identical electrical performance characteristics (impedance, ripple current) and physical dimensions while providing ROHS3 compliance. This part is recommended for direct replacement in active designs.

Performance-Enhanced Alternatives (Lower Impedance, Higher Ripple Current): The EKZM350ELL152MK30S (Chemi-Con KZM series), 35ZLH1500MEFC12.5X30 (Rubycon ZLH series), and EEU-FR1V152L (Panasonic FR-A series) offer reduced impedance (13 mOhms versus 20 mOhms) and increased ripple current handling capability. These parts are suitable for applications requiring improved thermal performance and lower ESR characteristics. All three are ROHS3 compliant and active in production.

Compact Form Factor Alternative: The EEU-FS1V152 (Panasonic FS-A series) provides the most compact height at 1.063 inches while maintaining all core electrical specifications. This part is suitable for space-constrained applications and is ROHS3 compliant.

Legacy Compatibility (Not For New Designs): The UHE1V152MHD (Nichicon UHE series) maintains electrical equivalence but carries a "Not For New Designs" status. This part is suitable only for legacy system maintenance and repair. REACH status indicates affected substances; verify compliance requirements for your application.

Selection Criteria:

• For RoHS compliance upgrades: Select EKY-350ELL152MK35S
• For improved thermal performance: Select EKZM350ELL152MK30S, 35ZLH1500MEFC12.5X30, or EEU-FR1V152L
• For space-constrained designs: Select EEU-FS1V152
• For legacy system support only: Select UHE1V152MHD

Frequently Asked Questions (FAQ)

Q: Can I substitute the KY35VB152M12X35LL with any of these parts directly on my PCB?

A: Yes, all listed substitute parts maintain identical lead spacing (0.197" / 5.00mm), diameter (0.492" / 12.50mm), and through-hole mounting characteristics. Physical height variations exist; verify clearance in your specific PCB layout. The EEU-FS1V152 is notably shorter (1.063" versus 1.378"), which may provide additional clearance in compact designs.

Q: What is the difference between the KY35VB152M12X35LL and EKY-350ELL152MK35S?

A: Both are Chemi-Con KY series parts with identical electrical specifications and physical dimensions. The primary difference is RoHS compliance status: KY35VB152M12X35LL is non-compliant, while EKY-350ELL152MK35S is ROHS3 compliant. Electrical performance (impedance, ripple current) is identical.

Q: Why do some substitute parts have lower impedance values?

A: Lower impedance indicates improved internal construction and reduced equivalent series resistance. Parts such as EKZM350ELL152MK30S (13 mOhms) and 35ZLH1500MEFC12.5X30 (13 mOhms) represent performance enhancements over the original 20 mOhms specification. Lower impedance results in reduced heat generation and improved ripple current handling capability.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts except the original KY35VB152M12X35LL are ROHS3 compliant. The UHE1V152MHD is compliant but carries "Not For New Designs" status and has REACH-affected substances. For new designs, select from the active, ROHS3-compliant alternatives.

Q: What is the significance of "Not For New Designs" status for the UHE1V152MHD?

A: This designation indicates the part is in mature or declining production phase. While functionally equivalent and currently in stock, Nichicon does not recommend this part for new product designs. Use this part only for maintenance, repair, or legacy system support where the original part number is required.

Q: Can I use the compact EEU-FS1V152 in place of the original part if my PCB has height constraints?

A: Yes. The EEU-FS1V152 is 0.315 inches shorter (1.063" versus 1.378") while maintaining all core electrical specifications. Verify that the reduced height does not affect thermal dissipation requirements in your specific application. All other mechanical parameters (lead spacing, diameter, mounting type) are identical.

Q: Which substitute part offers the best thermal performance?

A: The EEU-FR1V152L offers the highest ripple current capability at 2.904 A @ 120 Hz and 3.63 A @ 100 kHz, combined with low impedance (13 mOhms). The 35ZLJ1500M12.5X30 also provides excellent performance with 2.196 A @ 120 Hz and 3.66 A @ 100 kHz at 18 mOhms impedance. Both are suitable for applications requiring superior thermal characteristics.

Q: Are there any inventory considerations when selecting a substitute?

A: Current inventory levels vary significantly. The 35ZLH1500MEFC12.5X30 has the highest availability at 14,604 units. The original KY35VB152M12X35LL has 794 units available. Verify current stock status with your supplier before finalizing part selection for production quantities.

Q: What is the operating temperature range for all these parts?

A: All substitute parts maintain the identical operating temperature range of -40°C to 105°C with 10,000-hour lifetime rating at 105°C. This specification is consistent across all manufacturers and series listed.
