Key Parameters

Substitute Part Grouping Explanation

Substitution of the 35ML220MEFCT810X9 is determined by the following critical parameters:

• Capacitance Value: Must remain 220 µF to maintain circuit functionality
• Voltage Rating: Substitute must meet or exceed 35 V; higher voltage ratings provide additional safety margin
• Tolerance: ±20% tolerance is acceptable for general-purpose applications
• Polarization: Polar configuration required for electrolytic capacitor function
• Lead Spacing & Dimensions: 0.197" (5.00 mm) lead spacing and 0.394" (10.00 mm) diameter are standard for PCB compatibility
• Mounting Type: Through-hole radial configuration required for mechanical fit
• Compliance: RoHS3 compliance maintained across substitutes

The 50ZLH220MEFC10X16 qualifies as a direct substitute based on matching capacitance, tolerance, lead spacing, diameter, mounting type, and compliance certifications. The higher voltage rating (50 V vs. 35 V) and extended lifetime (10000 Hrs vs. 5000 Hrs @ 105°C) represent performance improvements suitable for replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The 50ZLH220MEFC10X16 is the qualified substitute for the 35ML220MEFCT810X9. Selection is based on:

• Active Product Status: The substitute carries Active status, ensuring continued availability and manufacturing support, whereas the original part is designated Not For New Designs
• Compliance Maintenance: Both parts maintain ROHS3 compliance and identical REACH/ECCN classifications
• Electrical Compatibility: Identical capacitance, tolerance, and lead spacing ensure direct PCB compatibility
• Performance Enhancement: The 50 V voltage rating provides increased design margin over the 35 V original specification
• Reliability Improvement: Extended lifetime rating (10000 Hrs vs. 5000 Hrs @ 105°C) supports longer service life requirements

The primary design consideration is the increased height (0.689" vs. 0.413"), which must be verified against available PCB clearance in the target application.

Frequently Asked Questions (FAQ)

Q: Can the 50ZLH220MEFC10X16 be used as a direct replacement for the 35ML220MEFCT810X9?

A: Yes, provided PCB clearance accommodates the increased height of 0.689" (17.50 mm) versus the original 0.413" (10.50 mm). All electrical parameters, lead spacing, and mounting configuration are compatible.

Q: What is the significance of the higher 50 V voltage rating on the substitute?

A: The 50 V rating on the 50ZLH220MEFC10X16 exceeds the original 35 V specification, providing additional safety margin and stress reduction during operation. This is a performance improvement with no negative impact on circuit function.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance, REACH status, and ECCN classifications. Substitution does not introduce compliance risks.

Q: Why is the original part marked "Not For New Designs"?

A: This designation indicates the 35ML220MEFCT810X9 is in end-of-life status. The 50ZLH220MEFC10X16, with Active status, is the recommended path forward for new designs and ongoing production.

Q: What is the impact of the increased ripple current rating on the substitute?

A: The 50ZLH220MEFC10X16 supports 685 mA ripple current at 120 Hz compared to 360 mA on the original part. This represents improved thermal performance and is not a limiting factor for substitution.

Q: Must PCB layout be modified to accommodate the substitute?

A: PCB footprint remains unchanged due to identical lead spacing (5.00 mm) and diameter (10.00 mm). Vertical clearance above the PCB must be verified to accommodate the 7.00 mm height increase.
