Key Parameters

Substitute Part Grouping Explanation

Substitution of the 35ZL56MEFCTA8X7 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Capacitance: 56 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.197" (5.00mm) (exact match required)
• Package / Case: Radial, Can (exact match required)

Allowable Variation Parameters:

• Voltage - Rated: Equal to or greater than 35 V
• Lifetime @ Temperature: Equal to or greater than 1000 Hrs @ 105°C
• Physical dimensions (diameter and height): Equal to or less than specified maximums to ensure PCB fit
• Operating Temperature Range: Must encompass -40°C ~ 105°C minimum

The substitute part Rubycon 100ZLJ56MT810X12.5 meets all mandatory compatibility parameters while providing enhanced electrical performance through higher voltage rating (100 V) and extended lifetime (9000 Hrs @ 105°C). Physical dimensions are larger, requiring verification of available PCB space.

Parameter Comparison

Engineering Selection Recommendations

The Rubycon 100ZLJ56MT810X12.5 is a valid substitute for the 35ZL56MEFCTA8X7 based on the following factors:

Product Status Consideration: The main part is in Last Time Buy status, making the Active status of the substitute part advantageous for long-term supply chain continuity.

Compliance Alignment: Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory consistency in applications requiring these certifications.

Electrical Performance: The substitute part provides higher voltage rating (100 V versus 35 V) and significantly extended lifetime (9000 Hrs @ 105°C versus 1000 Hrs @ 105°C), delivering improved reliability margins in the same capacitance and tolerance class.

Physical Compatibility Constraint: The substitute part has larger physical dimensions (0.394" diameter and 0.551" height versus 0.315" diameter and 0.315" height). PCB layout verification is required to confirm available mounting space before implementation.

Frequently Asked Questions (FAQ)

Q: Can the 100ZLJ56MT810X12.5 be used as a direct drop-in replacement for the 35ZL56MEFCTA8X7?

A: Electrical compatibility is confirmed. However, the substitute part has larger physical dimensions. Verify that PCB layout accommodates the increased diameter (0.394" versus 0.315") and height (0.551" versus 0.315") before installation.

Q: What are the key differences between these two parts?

A: Both parts share identical capacitance (56 µF), tolerance (±20%), lead spacing (5.00mm), and mounting type (Through Hole Radial). The substitute part offers higher voltage rating (100 V versus 35 V) and extended lifetime (9000 Hrs versus 1000 Hrs at 105°C). Physical dimensions are larger in the substitute part.

Q: Is the higher voltage rating of the substitute part a concern for the original circuit design?

A: No. A higher voltage rating does not negatively impact circuit operation. The capacitor will function correctly in circuits designed for 35 V operation. The higher rating provides additional safety margin.

Q: Why is the main part in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer has discontinued production of the 35ZL56MEFCTA8X7. The substitute part 100ZLJ56MT810X12.5 maintains Active status, ensuring continued availability.

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

A: Both parts are ROHS3 compliant and REACH Unaffected. No compliance differences exist between the two parts.

Q: What should be verified before implementing the substitute part?

A: Confirm PCB layout accommodates the larger physical dimensions of the substitute part. Verify that the higher voltage rating and extended lifetime do not introduce cost or performance considerations for the application.
