Key Parameters

Substitute Part Grouping Explanation

Substitution of the KZE35VB331M10X16LL is determined by strict equivalence in the following parameters:

Critical Parameters (Must Match):

• Capacitance: 330 µF
• Voltage Rating: 35 V
• Tolerance: ±20%
• Mounting Type: Through Hole
• Package Type: Radial, Can
• Lead Spacing: 0.197" (5.00mm)
• Case Diameter: 0.394" (10.00mm)
• Polarization: Polar

Compatible Variation Parameters:

• Lifetime @ 105°C: Equal to or greater than 4000 hours
• Height: Physical height may vary within PCB layout constraints
• Ripple Current: May vary based on impedance characteristics
• Impedance: May vary based on manufacturer design
• Operating Temperature Range: Must encompass -40°C to 105°C minimum

All substitute parts listed maintain the critical electrical and mechanical parameters required for direct replacement in applications designed for the KZE35VB331M10X16LL.

Parameter Comparison

Engineering Selection Recommendations

For New Designs:

The EKZE350ELL331MJ16S (Chemi-Con) is the primary upgrade path. This part maintains identical electrical specifications to the original KZE35VB331M10X16LL while offering active product status and ROHS3 compliance. The height increase of 0.059" (1.50mm) requires PCB layout verification but presents no functional impediment.

The EEU-EB1V331 (Panasonic) provides extended lifetime performance at 10000 hours @ 105°C with active product status and ROHS3 compliance. This option is suitable for applications requiring enhanced reliability margins.

The EEU-FM1V331 (Panasonic) offers identical 4000-hour lifetime with active product status and ROHS3 compliance. The lower impedance of 26 mOhms provides improved ripple current handling characteristics.

For Existing Designs:

The 35ZLQ330MEFC10X12.5 (Rubycon) provides a compact form factor with reduced height (0.551" vs. 0.630") and extended 5000-hour lifetime. This option is suitable for space-constrained applications.

Not Recommended for New Designs:

The UHE1V331MPD and UPW1V331MPD (Nichicon) carry "Not For New Designs" status and should be used only for legacy system maintenance or repair applications where original specifications must be maintained.

Frequently Asked Questions (FAQ)

Q: Can the KZE35VB331M10X16LL be directly replaced with EKZE350ELL331MJ16S?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (35 V), tolerance (±20%), lead spacing (5.00mm), and case diameter (10.00mm). The height difference of 0.059" (1.50mm) requires verification that PCB layout accommodates the taller component, but electrical substitution is direct.

Q: What is the primary advantage of EEU-EB1V331 over the original part?

A: The EEU-EB1V331 provides 10000 hours lifetime at 105°C compared to 4000 hours for the KZE35VB331M10X16LL. This extended rating provides improved reliability for applications requiring longer operational life. All other critical parameters remain equivalent.

Q: Are there height restrictions when selecting a substitute?

A: Height variations exist among substitute parts. The original KZE35VB331M10X16LL measures 0.630" (16.00mm). Substitutes range from 0.551" (14.00mm) to 0.689" (17.50mm). PCB layout must accommodate the selected substitute's height to ensure proper component seating and clearance.

Q: Why are UHE1V331MPD and UPW1V331MPD marked "Not For New Designs"?

A: These parts carry legacy status designations indicating they are maintained for existing product support only. New designs should utilize parts with active product status such as EKZE350ELL331MJ16S, EEU-EB1V331, or EEU-FM1V331.

Q: What is the significance of ROHS3 compliance?

A: ROHS3 compliance indicates the part meets current Restriction of Hazardous Substances regulations. The original KZE35VB331M10X16LL is non-compliant. All listed substitutes are ROHS3 compliant, making them suitable for applications subject to environmental and regulatory requirements.

Q: Can impedance differences affect circuit performance?

A: Impedance variations among substitutes (ranging from 26 mOhms to 68 mOhms) reflect different internal construction. For general-purpose applications, these variations are within acceptable operating parameters. Applications with specific ripple current or frequency response requirements should verify impedance specifications against circuit design criteria.

Q: Is the 35ZLQ330MEFC10X12.5 suitable for space-constrained applications?

A: Yes. The 35ZLQ330MEFC10X12.5 offers the most compact height at 0.551" (14.00mm), approximately 0.079" shorter than the original part. This option is appropriate for applications where vertical PCB space is limited, provided lead spacing and case diameter requirements are met.
