Substitute Part Grouping Explanation

Substitution of the T86D106M025EBAS is determined by strict equivalence in the following parameters:

Critical Parameters for Substitution:

• Capacitance value: 10 µF (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• ESR: 1 Ohm (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Moisture Sensitivity Level: 1 (exact match required)

Allowable Parameter Variations:

• Voltage Rating: Substitute parts may have equal or higher voltage ratings
• Tolerance: Substitute parts may have equal or tighter tolerance specifications
• Product Status: Active parts are preferred over obsolete classifications

The substitute part T493D106K035BH61107505 meets all critical parameters while providing improved voltage rating (35 V versus 25 V) and tighter tolerance (±10% versus ±20%), with active product status.

Engineering Selection Recommendations

The T493D106K035BH61107505 from KEMET is the direct substitute for the obsolete T86D106M025EBAS. Selection of this substitute is based on the following engineering criteria:

Product Status: The substitute part carries active product status, ensuring long-term availability and manufacturing support, whereas the main part is classified as obsolete.

Electrical Compatibility: The substitute maintains identical capacitance (10 µF), ESR (1 Ohm), and operating temperature range (-55°C to 125°C). The increased voltage rating (35 V versus 25 V) provides additional design margin without affecting circuit performance in applications rated for 25 V operation.

Mechanical Compatibility: Both parts share identical package dimensions (2917 / 7343 Metric), height specifications, and surface mount mounting type, ensuring direct PCB layout compatibility.

Tolerance Improvement: The substitute offers ±10% tolerance compared to ±20% for the main part, providing tighter capacitance control for applications requiring improved performance consistency.

Compliance and Reliability: The substitute includes specified lifetime rating (2000 Hrs @ 125°C) and failure rate data (B, 0.1%), supporting high-reliability application requirements. Both parts maintain MSL 1 classification and identical ECCN/HTSUS coding.

Frequently Asked Questions (FAQ)

Q: Can the T493D106K035BH61107505 be used as a direct replacement for the T86D106M025EBAS?

A: Yes. Both parts share identical capacitance (10 µF), package dimensions (2917 / 7343 Metric), ESR (1 Ohm), and operating temperature range (-55°C to 125°C). The substitute features higher voltage rating (35 V) and tighter tolerance (±10%), both of which are compatible with applications designed for the original part.

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

A: The T493D106K035BH61107505 is rated for 35 V operation compared to 25 V for the original part. In applications operating at or below 25 V, the higher rating provides additional design margin and does not negatively impact circuit performance. The substitute remains fully compatible with 25 V circuit designs.

Q: Are there any PCB layout changes required when substituting this part?

A: No. Both parts use identical 2917 (7343 Metric) package dimensions and surface mount configuration. PCB footprints, land patterns, and assembly processes remain unchanged.

Q: What is the difference in tolerance between these parts?

A: The original T86D106M025EBAS carries ±20% tolerance, while the substitute T493D106K035BH61107505 carries ±10% tolerance. The tighter tolerance of the substitute provides improved capacitance accuracy for applications requiring closer component value control.

Q: Why is the original part classified as obsolete?

A: The T86D106M025EBAS is listed as obsolete by the manufacturer. The T493D106K035BH61107505 is an active product offering equivalent electrical and mechanical specifications with improved reliability documentation and long-term availability assurance.

Q: Are moisture sensitivity levels identical between these parts?

A: Yes. Both parts carry MSL 1 (Unlimited) classification, indicating identical moisture handling and storage requirements.
