Substitute Part Grouping Explanation
Substitution of the EKZE160ELL331MHB5D is determined by the following critical parameters:
Mandatory Compatibility Parameters:
- Capacitance: 330 µF (exact match required)
- Tolerance: ±20% (exact match required)
- Mounting Type: Through Hole (exact match required)
- Package Type: Radial, Can (exact match required)
- Lead Spacing: 0.138" (3.50 mm) (exact match required)
- Diameter: 0.315" (8.00 mm) (exact match required)
- Polarization: Polar (exact match required)
Voltage Rating Consideration: Substitute parts may operate at equal or higher voltage ratings than the original 16 V specification. A 25 V rated capacitor can substitute for a 16 V application without electrical incompatibility.
Performance Enhancement Parameters:
- Lifetime at 105°C: May be equal to or exceed 3000 hours
- Ripple Current Capability: May be equal to or exceed original specifications
- Impedance: Lower impedance values indicate improved performance
- Operating Temperature Range: May be equal to or extend the original -40°C to 105°C range
Product Status Consideration: Parts marked "Active" are preferred for new designs. Parts marked "Not For New Designs" are suitable for replacement and maintenance applications only.

Engineering Selection Recommendations
Same Voltage Rating (16 V) Substitutes:
The ELXZ160ELL331MH12D from Chemi-Con maintains the 16 V voltage rating while offering extended operating temperature range (-55°C to 105°C) and is rated for automotive applications with AEC-Q200 compliance. This part is suitable for applications requiring enhanced temperature performance. Height is 13.50 mm compared to the original 13.00 mm; verify clearance in the target application.
The 16YXF330MEFC8X11.5 from Rubycon provides a 16 V rating with extended lifetime (7000 hours at 105°C) but carries "Not For New Designs" status. This part is suitable for replacement and maintenance applications where the original component is no longer available.
Higher Voltage Rating (25 V) Substitutes:
All 25 V rated substitutes are electrically compatible with the 16 V application. Selection among 25 V options depends on lifetime requirements and product status:
- EKZM250ELL331MHB5D (Chemi-Con, KZM series): 8000 hours at 105°C, Active status. Recommended for applications requiring extended operational life.
- 25ZLJ330M8X11.5 (Rubycon, ZLJ series): 9000 hours at 105°C, Active status, highest inventory (75891 units). Recommended for high-volume applications and extended service life requirements.
- 25ZLH330MEFC8X11.5 (Rubycon, ZLH series): 8000 hours at 105°C, Active status. Suitable for general-purpose applications requiring improved performance.
- EKYB250ELL331MHB5D (Chemi-Con, KYB series): 7000 hours at 105°C, Active status. Suitable for applications requiring moderate lifetime extension.
Parts marked "Not For New Designs" (16YXF330MEFC8X11.5, 25YXG330MEFC8X11.5) are suitable for replacement applications only and should not be selected for new product designs.
All substitute parts maintain RoHS3 compliance and identical mechanical dimensions (lead spacing, diameter) except ELXZ160ELL331MH12D, which has a 0.5 mm height increase.
Frequently Asked Questions (FAQ)
Q: Can a 25 V rated capacitor replace a 16 V rated capacitor?
A: Yes. A capacitor with a higher voltage rating can be used in an application designed for a lower voltage. The 25 V rated substitutes are electrically compatible with the 16 V application and provide the same capacitance value (330 µF) with identical mechanical dimensions and lead spacing.
Q: What is the difference between "Active" and "Not For New Designs" product status?
A: "Active" parts are currently in production and recommended for new designs. "Not For New Designs" parts are still available but no longer recommended for new product development; they are suitable for replacement and maintenance of existing equipment. For new designs, select only parts with "Active" status.
Q: Does the ELXZ160ELL331MH12D fit in the same PCB footprint?
A: The ELXZ160ELL331MH12D has identical lead spacing (3.50 mm) and diameter (8.00 mm) but a maximum seated height of 13.50 mm compared to 13.00 mm for the original part. Verify that the additional 0.5 mm height does not interfere with components or enclosure clearances in your application.
Q: Which substitute offers the longest operational lifetime?
A: The 25ZLJ330M8X11.5 from Rubycon offers 9000 hours at 105°C, the highest lifetime rating among all substitutes. This part is Active status and has the largest inventory (75891 units).
Q: Are all substitutes RoHS3 compliant?
A: Yes. All substitute parts listed are RoHS3 compliant, matching the compliance status of the original EKZE160ELL331MHB5D.
Q: What is the significance of impedance values in capacitor selection?
A: Impedance indicates the capacitor's resistance to alternating current at specific frequencies. Lower impedance values indicate better high-frequency performance and improved ripple current handling. For example, the 25ZLJ330M8X11.5 has 75 mOhms impedance compared to 72 mOhms for the original part, representing comparable performance.
Q: Can I use a substitute with a different manufacturer?
A: Yes. All listed substitutes maintain identical capacitance (330 µF), tolerance (±20%), mechanical dimensions, lead spacing, and mounting type. Rubycon and Chemi-Con parts are both qualified manufacturers. Verify that your application does not have specific manufacturer requirements before substitution.
Q: What ripple current specifications should I consider?
A: Ripple current capability is provided at two frequencies: 120 Hz (low frequency) and 100 kHz (high frequency). The original EKZE160ELL331MHB5D is rated for 380 mA at 120 Hz and 760 mA at 100 kHz. Higher ripple current ratings indicate improved performance in applications with significant AC current components. Select substitutes with equal or higher ripple current ratings for your specific frequency requirements.
