T86D106K025ESSS Equivalent & Substitute Parts

Part Overview

The T86D106K025ESSS is a 10 µF molded tantalum capacitor manufactured by Vishay Sprague, rated for 25 V operation in a 2917 (7343 Metric) surface mount package. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The part features a fail-safe design with built-in fuse and is rated for COTS applications with unlimited moisture sensitivity level (MSL 1).

Key Parameters

Substitute Part Grouping Explanation

Substitution of the T86D106K025ESSS is determined by strict equivalence in the following parameters:

• Capacitance value: 10 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Type: Molded tantalum (exact match required)
• ESR: 1 Ohm (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• Mounting type: Surface mount (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Physical dimensions: 0.287" L x 0.169" W, height 0.122" max (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The rated voltage may be equal to or higher than the original specification, provided all other parameters remain unchanged. Substitute parts must maintain identical mechanical and electrical characteristics to ensure direct replacement capability without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The T493D106K035BH61107505 (KEMET) is a direct substitute for the T86D106K025ESSS. The substitute part maintains identical capacitance, tolerance, ESR, operating temperature range, mounting type, package dimensions, and moisture sensitivity level. The rated voltage is increased from 25 V to 35 V, which provides additional design margin without affecting circuit compatibility.

The primary advantage of this substitution is product status: the KEMET part is active and currently in production, whereas the Vishay Sprague original is obsolete. Both parts carry identical RoHS non-compliant and REACH status classifications. The KEMET substitute includes documented lifetime rating (2000 Hrs @ 125°C) and failure rate data (B, 0.1%), supporting long-term reliability assessment.

Frequently Asked Questions (FAQ)

Q: Can the T493D106K035BH61107505 be used as a direct replacement for the T86D106K025ESSS?

A: Yes. Both parts share identical capacitance (10 µF), tolerance (±10%), ESR (1 Ohm), operating temperature range (-55°C to 125°C), mounting type (surface mount), package designation (2917/7343 Metric), physical dimensions (0.287" L x 0.169" W, 0.122" max height), and moisture sensitivity level (MSL 1). The higher voltage rating (35 V vs. 25 V) does not prevent substitution and provides additional design margin.

Q: Are there any physical compatibility concerns with this substitution?

A: No. Both parts use identical package codes (2917/7343 Metric) with matching dimensions and height specifications. PCB footprints and assembly processes remain unchanged.

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

A: The substitute part is rated for 35 V compared to the original 25 V specification. This higher rating does not affect compatibility in circuits designed for 25 V operation. The component will function identically within the original circuit voltage parameters.

Q: Does the substitute part have the same reliability features as the original?

A: Both parts are molded tantalum capacitors with 1 Ohm ESR and identical operating temperature ranges. The KEMET substitute provides documented lifetime rating and failure rate data, supporting reliability analysis. The original Vishay Sprague part included fail-safe design with built-in fuse; verify specific application requirements if this feature is critical.

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

A: Both parts are RoHS non-compliant and REACH Unaffected/Affected respectively. Both carry COTS ratings and identical ECCN and HTSUS classifications. Compliance requirements should be evaluated based on end-application specifications.
