35YXH680MEFCT810X28 Equivalent & Substitute Parts

Part Overview

The Rubycon 35YXH680MEFCT810X28 is a 680 µF, 35 V aluminum electrolytic capacitor in radial, can package configuration. This component is classified as Last Time Buy, indicating discontinued production status. The part operates across a temperature range of -40°C to 105°C with a rated lifetime of 7000 hours at 105°C, suitable for general-purpose applications requiring stable capacitance and ripple current handling.

Identifying equivalent and substitute parts becomes necessary due to the Last Time Buy status, which restricts future availability. Direct substitutes with active production status and improved performance characteristics are available from both Rubycon and Panasonic Electronic Components.

Substitute Part Grouping Explanation

Substitution eligibility for the 35YXH680MEFCT810X28 is determined by the following mandatory parameters:

• Capacitance: 680 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage - Rated: 35 V (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (exact match required)
• Polarization: Polar (exact match required)
• Lead Spacing: 0.197" (5.00mm) (exact match required)
• Size / Dimension: 0.394" Dia (10.00mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

All identified substitute parts meet these mandatory criteria. Variations in secondary parameters such as lifetime at temperature, ripple current ratings, impedance, height, and packaging format (Tape & Box versus Cut Tape) do not disqualify substitution eligibility but may influence selection based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—35ZLH680MEFCT810X23, EEU-FR1V681B, and EEU-FR1V681LB—are functionally equivalent to the 35YXH680MEFCT810X28 based on mandatory electrical and mechanical parameters. Selection among these options should be based on the following factors:

Product Status and Availability: The 35YXH680MEFCT810X28 carries Last Time Buy status, restricting future procurement. All substitute parts maintain Active product status, ensuring long-term availability and supply chain continuity.

Compliance and Certifications: All parts are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Manufacturer Continuity: The Rubycon 35ZLH680MEFCT810X23 maintains the same manufacturer as the original part, providing consistency in manufacturing processes and quality standards. Panasonic Electronic Components parts (EEU-FR1V681B and EEU-FR1V681LB) represent cross-manufacturer alternatives with established reliability records.

Performance Enhancements: All substitute parts offer improved lifetime ratings (10000 Hrs @ 105°C versus 7000 Hrs @ 105°C), lower impedance values, and higher ripple current capabilities, providing enhanced performance margins in general-purpose applications.

Physical Dimensions: Height variations exist among substitutes (22.00mm to 27.00mm versus 30.00mm original). PCB layout constraints should be evaluated to confirm compatibility with available mounting space.

Frequently Asked Questions (FAQ)

Q: Can the 35ZLH680MEFCT810X23 directly replace the 35YXH680MEFCT810X28 in existing designs?

A: Yes. Both parts share identical capacitance (680 µF), voltage rating (35 V), tolerance (±20%), operating temperature range (-40°C to 105°C), lead spacing (5.00mm), and can diameter (10.00mm). The 35ZLH680MEFCT810X23 is shorter (25.00mm versus 30.00mm height), which may require PCB layout verification but does not affect electrical compatibility.

Q: What is the difference between Tape & Box (TB) and Cut Tape (CT) packaging?

A: Tape & Box packaging supplies components on tape within a protective box, typically for manual assembly or smaller volume applications. Cut Tape packaging provides components on tape cut to specified lengths, optimized for automated assembly processes. Both formats contain identical components; packaging selection depends on assembly methodology and volume requirements.

Q: Are Panasonic EEU-FR series parts compatible with Rubycon YXH and ZLH series?

A: Yes. The Panasonic EEU-FR1V681B and EEU-FR1V681LB meet all mandatory electrical and mechanical parameters required for substitution. Cross-manufacturer compatibility is established through matching capacitance, voltage, tolerance, temperature range, lead spacing, and package configuration.

Q: How do ripple current ratings affect part selection?

A: Ripple current ratings indicate the maximum AC current the capacitor can handle at specified frequencies. Higher ripple current capability (as provided by substitute parts) allows operation in higher-current applications without thermal stress. If the original design operates within the 35YXH680MEFCT810X28 ripple current limits, substitute parts with higher ratings provide additional performance margin.

Q: Does the improved lifetime rating (10000 Hrs versus 7000 Hrs) require design changes?

A: No. The improved lifetime rating represents enhanced reliability and extended operational life under identical temperature conditions. Existing designs require no modification; the longer lifetime provides extended service intervals and reduced maintenance requirements.

Q: What compliance certifications apply to all substitute parts?

A: All parts maintain ROHS3 Compliance and REACH Unaffected status, meeting current environmental and regulatory standards for electronic component manufacturing, distribution, and end-of-life management.
