T86C474K050ESAS Equivalent & Substitute Parts

Part Overview

The T86C474K050ESAS is a 0.47 µF molded tantalum capacitor rated for 50 V operation in a 2312 (6032 Metric) surface mount package. This component is part of Vishay Sprague's TANTAMOUNT™ T86 series and is classified as obsolete. Due to its obsolete status, identifying functionally equivalent active alternatives is necessary for ongoing design support, production continuity, and component sourcing.

Substitute Part Grouping Explanation

The 293D474X9050C2TE3 qualifies as a direct substitute for the T86C474K050ESAS based on the following critical parameters:

• Identical capacitance value: 0.47 µF
• Identical tolerance: ±10%
• Identical rated voltage: 50 V
• Identical ESR: 6.7 Ohm
• Identical operating temperature range: -55°C to 125°C
• Identical package type: 2312 (6032 Metric)
• Identical physical dimensions: 0.236" L x 0.126" W (6.00mm x 3.20mm)
• Identical MSL rating: 1 (Unlimited)
• Identical manufacturer: Vishay Sprague

The substitute part differs in product status (active versus obsolete) and RoHS compliance, making it suitable for replacement in new designs and ongoing production.

Parameter Comparison

Engineering Selection Recommendations

The 293D474X9050C2TE3 is the appropriate replacement for the obsolete T86C474K050ESAS. Selection is based on:

• Product status: The substitute is active and currently manufactured, ensuring long-term availability and supply chain continuity.
• Electrical equivalence: All critical electrical parameters (capacitance, voltage rating, ESR, temperature range) are identical.
• Physical compatibility: Package dimensions and mounting type are identical, enabling direct PCB layout compatibility.
• Compliance: The substitute meets ROHS3 compliance requirements, supporting modern regulatory standards.
• Seated height variance: The substitute height of 2.79mm versus the original 2.80mm represents a negligible 0.01mm difference and does not impact assembly or clearance considerations.

Frequently Asked Questions (FAQ)

Q: Can the 293D474X9050C2TE3 be used as a direct replacement on existing PCBs designed for the T86C474K050ESAS?

A: Yes. The substitute part is electrically and physically equivalent. Identical package dimensions, mounting type, and electrical characteristics ensure direct compatibility without PCB redesign.

Q: What is the significance of the RoHS compliance difference?

A: The substitute part is ROHS3 compliant, meeting current environmental and regulatory standards. The original part is RoHS non-compliant due to its obsolete status. For new designs and production, the compliant substitute is the appropriate choice.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts operate across the identical temperature range (-55°C to 125°C) and maintain the same ESR specification of 6.7 Ohm, ensuring equivalent thermal and electrical performance.

Q: What is the packaging difference, and does it affect selection?

A: The original part is supplied in bulk packaging, while the substitute is supplied in Tape & Reel (TR) format. This difference affects handling and assembly processes but does not impact electrical or mechanical compatibility.

Q: Is the 0.01mm height difference significant?

A: No. The seated height difference of 0.01mm (2.80mm versus 2.79mm) is within manufacturing tolerance and does not affect PCB clearance, component placement, or assembly processes.
