Key Parameters

Substitute Part Grouping Explanation

Substitution of the T86E336M025ESSL is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Capacitance value: 33 µF (exact match required)
• Package / Case: 2917 (7343 Metric) (physical and electrical compatibility)
• Mounting Type: Surface Mount (assembly compatibility)
• ESR: 300 mOhm (electrical performance equivalence)
• Operating Temperature Range: -55°C to 125°C (thermal compatibility)

Allowable Variation Parameters:

• Voltage Rating: May be equal to or greater than 25 V (higher voltage rating provides design margin)
• Tolerance: May be tighter than ±20% (improved accuracy is acceptable)

The substitute part TBJE336K035LBSB0024 meets all mandatory compatibility requirements with an upgraded voltage rating of 35 V and improved tolerance of ±10%, making it a direct functional equivalent for applications requiring the T86E336M025ESSL.

Parameter Comparison

Engineering Selection Recommendations

The TBJE336K035LBSB0024 is the qualified substitute for the T86E336M025ESSL based on the following engineering criteria:

Product Status Alignment: The substitute part carries Active product status, ensuring long-term availability and manufacturing support, whereas the original part is Obsolete.

Electrical Equivalence: Both parts maintain identical capacitance (33 µF) and ESR (300 mOhm) specifications. The substitute's 35 V rating exceeds the original 25 V requirement, providing additional design margin without compromising circuit performance.

Physical Compatibility: Dimensional specifications are equivalent within manufacturing tolerances, with the substitute measuring 0.168" (4.26mm) in seated height compared to the original 0.169" (4.30mm), ensuring PCB assembly compatibility.

Tolerance Improvement: The substitute's ±10% tolerance is tighter than the original ±20%, offering improved capacitance accuracy for precision applications.

Compliance Equivalence: Both parts maintain identical RoHS and REACH compliance status, with no change to regulatory standing.

Frequently Asked Questions (FAQ)

Q: Can the TBJE336K035LBSB0024 be used as a direct replacement for the T86E336M025ESSL?

A: Yes. Both parts share identical capacitance (33 µF), ESR (300 mOhm), package (2917 / 7343 Metric), and operating temperature range (-55°C to 125°C). The substitute's higher voltage rating (35 V vs. 25 V) and improved tolerance (±10% vs. ±20%) make it functionally equivalent and suitable for direct substitution.

Q: What is the significance of the voltage rating difference?

A: The substitute's 35 V rating exceeds the original 25 V specification. In circuit applications, using a capacitor with a higher voltage rating than required does not degrade performance and provides additional safety margin. No circuit redesign is necessary.

Q: Are the physical dimensions compatible with existing PCB layouts?

A: Yes. Both parts use the 2917 (7343 Metric) package with dimensions of 0.287" L x 0.169" W (7.30mm x 4.30mm). The substitute's seated height of 0.168" (4.26mm) is within the tolerance of the original 0.169" (4.30mm), ensuring compatibility with existing PCB footprints and assembly processes.

Q: Does the tolerance improvement affect circuit design?

A: The substitute's ±10% tolerance is tighter than the original ±20%, meaning capacitance values will be closer to the nominal 33 µF specification. This improves circuit accuracy without requiring design modifications.

Q: Are there any compliance or regulatory differences?

A: No. Both parts maintain identical RoHS non-compliant and REACH Unaffected status. There is no change to regulatory or compliance standing when substituting these parts.

Q: Why is the original part obsolete?

A: The T86E336M025ESSL is classified as obsolete by the manufacturer, meaning it is no longer in active production. The TBJE336K035LBSB0024 from KYOCERA AVX is an active product with ongoing manufacturing support and availability.
