Key Parameters

Substitute Part Grouping Explanation

Substitution of the T86C684K050ESAS is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance value: 0.68 µF
• Tolerance: ±10%
• Voltage rating: 50 V
• ESR: 5.9 Ohm
• Operating temperature range: -55°C to 125°C
• Package type: 2312 (6032 Metric) surface mount
• Physical dimensions: 0.236" L x 0.126" W with maximum seated height of 0.110"
• Moisture sensitivity: MSL 1

The 293D684X9050C2TE3 meets all these criteria and is classified as an active product, making it a direct functional equivalent for the obsolete T86C684K050ESAS.

Parameter Comparison

Engineering Selection Recommendations

The 293D684X9050C2TE3 is the direct substitute for the obsolete T86C684K050ESAS. Both components are manufactured by Vishay Sprague and share identical electrical specifications and physical dimensions within tolerance. The primary distinction is product status: the 293D684X9050C2TE3 is an active product with current manufacturing support and improved RoHS3 compliance, whereas the T86C684K050ESAS is obsolete.

For new designs or production requiring 0.68 µF, 50 V molded tantalum capacitors in 2312 package format, the 293D684X9050C2TE3 is the appropriate selection. For legacy system maintenance where the original T86C684K050ESAS is specified, the 293D684X9050C2TE3 provides functional equivalence with the added benefit of active product status and improved regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the 293D684X9050C2TE3 be used as a direct replacement for the T86C684K050ESAS?

A: Yes. Both components have identical capacitance (0.68 µF), voltage rating (50 V), ESR (5.9 Ohm), operating temperature range (-55°C to 125°C), and package dimensions (2312/6032 Metric). The seated height difference of 0.01mm (2.80mm vs 2.79mm) is within standard manufacturing tolerance and does not affect PCB assembly or circuit performance.

Q: What is the primary reason to transition from the T86C684K050ESAS to the 293D684X9050C2TE3?

A: The T86C684K050ESAS is obsolete with no active manufacturing. The 293D684X9050C2TE3 is an active product with current inventory availability and manufacturing support. Additionally, the 293D684X9050C2TE3 meets ROHS3 compliance standards, whereas the T86C684K050ESAS does not.

Q: Are there any packaging differences between these parts?

A: The T86C684K050ESAS is supplied in standard packaging, while the 293D684X9050C2TE3 is available in Tape & Reel (TR) format. Both are surface mount components in the 2312 (6032 Metric) package with identical physical dimensions and mounting characteristics.

Q: What is the MSL rating for these capacitors?

A: Both the T86C684K050ESAS and 293D684X9050C2TE3 have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are these components suitable for high-reliability applications?

A: The T86C684K050ESAS includes fail-safe operation with built-in fuse protection and is rated for high-reliability applications. The 293D684X9050C2TE3 is classified as general purpose. Application-specific reliability requirements should be evaluated against the intended use case.
