Rubycon 35ML10MEFCTZ4X7 Equivalent & Substitute Parts

Part Overview

The Rubycon 35ML10MEFCTZ4X7 is a 10 µF, 35 V aluminum electrolytic capacitor in radial, can package configuration with a rated lifetime of 5000 hours at 105°C. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. The radial through-hole mounting and general-purpose application profile require substitute parts that maintain identical electrical performance and mechanical compatibility within the specified parameter tolerances.

Substitute Part Grouping Explanation

Substitution of the Rubycon 35ML10MEFCTZ4X7 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 10 µF (exact match required)
• Voltage rating: 35 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime specification: 5000 Hrs @ 105°C (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)
• Ripple current ratings: 28 mA @ 120 Hz and 42 mA @ 10 kHz (exact match required)
• Physical dimensions: 0.157" diameter, 0.315" height (exact match required)
• Mounting configuration: Through-hole radial, can package (exact match required)
• Compliance: ROHS3 Compliant (maintained)

The substitute part 35ML10MEFCT54X7 meets all electrical and thermal specifications. The primary distinction is lead spacing, which differs from the main part and must be evaluated for PCB layout compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Rubycon 35ML10MEFCT54X7 provides electrical and thermal equivalence to the 35ML10MEFCTZ4X7 across all specified performance parameters. Both components maintain ROHS3 compliance and identical capacitance, voltage, tolerance, and ripple current ratings.

The critical design consideration is lead spacing: the substitute part features 0.098" (2.50 mm) spacing compared to the original 0.197" (5.00 mm) spacing. PCB layout modification is required to accommodate this dimensional change. Physical dimensions (diameter and height) remain identical, permitting direct mechanical fit within the same envelope.

Both parts are classified as obsolete. Selection between them depends solely on PCB hole pattern compatibility and available inventory.

Frequently Asked Questions (FAQ)

Q: Can the 35ML10MEFCT54X7 be used as a direct replacement for the 35ML10MEFCTZ4X7?

A: Electrical and thermal performance are equivalent. However, the lead spacing differs (2.50 mm versus 5.00 mm), requiring PCB layout modification. Direct board-level substitution without layout changes is not possible.

Q: Are the physical dimensions identical?

A: Yes. Both components share identical diameter (0.157" / 4.00 mm) and height (0.315" / 8.00 mm) specifications. The difference is limited to lead spacing only.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the 35ML10MEFCTZ4X7 and 35ML10MEFCT54X7 are ROHS3 compliant and carry identical REACH and ECCN classifications.

Q: What is the significance of the lead spacing difference?

A: Lead spacing determines PCB hole pattern compatibility. The 2.50 mm spacing of the substitute part requires PCB redesign if the original 5.00 mm hole pattern is present. Mechanical fit within the component envelope is unaffected.

Q: Are both parts suitable for the same applications?

A: Yes. Both components are rated for general-purpose applications with identical electrical specifications: 10 µF capacitance, 35 V voltage rating, ±20% tolerance, 5000-hour lifetime at 105°C, and identical ripple current ratings.

Q: What should be considered when selecting between these parts?

A: Selection criteria are PCB layout compatibility (lead spacing) and component availability. Electrical performance and compliance are equivalent.
