T86C225K025ESAS Equivalent & Substitute Parts

Part Overview

The T86C225K025ESAS is a 2.2 µF molded tantalum capacitor rated for 25 V, manufactured by Vishay Sprague as part of the TANTAMOUNT™ T86 series. This component is designed for surface mount applications in the 2312 (6032 Metric) package format. The part is currently listed as obsolete, making identification of compatible substitute components essential for ongoing system support, repair, and new design implementations where legacy specifications must be maintained.

Substitute Part Grouping Explanation

Substitution for the T86C225K025ESAS is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance value: 2.2 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage rating: 25 V (exact match required)
• Package format: 2312 (6032 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

The substitute part 293D225X9025C2TE3 meets all these criteria. Variations in ESR (Equivalent Series Resistance), packaging format (Tape & Reel vs. bulk), and product status do not disqualify substitution when all primary electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

The 293D225X9025C2TE3 is the direct equivalent substitute for the T86C225K025ESAS. Both components are manufactured by Vishay Sprague and share identical electrical specifications (2.2 µF, ±10%, 25 V) and mechanical form factor (2312 package, surface mount).

The primary distinction is product status: the original T86C225K025ESAS is obsolete, while the 293D225X9025C2TE3 is active and currently in production. The substitute part carries ROHS3 compliance, whereas the original is RoHS non-compliant. ESR values differ slightly (2.8 Ohm vs. 3.2 Ohm), remaining within acceptable operational margins for most applications given the identical voltage and capacitance ratings.

For new designs or system replacements, the 293D225X9025C2TE3 is the appropriate selection. For legacy system maintenance requiring exact historical specifications, the original part number should be cross-referenced with available inventory before substitution is implemented.

Frequently Asked Questions (FAQ)

Q: Can the 293D225X9025C2TE3 be used as a direct replacement for the T86C225K025ESAS?

A: Yes. Both parts are 2.2 µF, 25 V molded tantalum capacitors in the 2312 (6032 Metric) package with identical electrical and mechanical specifications. The substitute is electrically and physically compatible.

Q: What is the significance of the ESR difference (2.8 Ohm vs. 3.2 Ohm)?

A: ESR (Equivalent Series Resistance) affects ripple current handling and thermal performance. The 0.4 Ohm difference is minor and does not alter the functional equivalence of these components for standard applications. Circuit-specific requirements should be evaluated if ESR is a critical design parameter.

Q: Why is the original part listed as obsolete?

A: The T86C225K025ESAS is part of the legacy T86 series. Vishay Sprague has transitioned production to the 293D series, which offers improved compliance (ROHS3) and continued manufacturing support.

Q: Are there packaging differences between these parts?

A: The T86C225K025ESAS is supplied in standard packaging, while the 293D225X9025C2TE3 is available in Tape & Reel (TR) format. Both use the identical 2312 (6032 Metric) component package. Tape & Reel packaging is standard for automated assembly processes.

Q: What is MSL 1 (Unlimited) moisture sensitivity?

A: MSL 1 indicates the lowest moisture sensitivity level. Components with this rating require no special moisture control during storage or handling, making them suitable for standard warehouse and assembly environments.

Q: Can the 293D225X9025C2TE3 be used in applications requiring RoHS non-compliant components?

A: No. The substitute part is ROHS3 compliant. If legacy RoHS non-compliant specifications are mandatory, the original T86C225K025ESAS must be sourced from available inventory.
