Substitute Part Grouping Explanation

Substitution of the T86C684K050EBAS is determined by strict equivalence across the following parameters:

• Capacitance value: 0.68 µF
• Tolerance: ±10%
• Rated voltage: 50 V
• Capacitor type: Molded tantalum
• ESR: 5.9 Ohm
• Operating temperature range: -55°C ~ 125°C
• Package: 2312 (6032 Metric) surface mount
• Physical dimensions and height compatibility

The substitute part 293D684X9050C2TE3 meets all these electrical and mechanical parameters, providing direct functional equivalence while offering the advantage of active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 293D684X9050C2TE3 is the direct equivalent for the obsolete T86C684K050EBAS. Both components share identical electrical specifications and mechanical compatibility. The substitute part offers two significant advantages: active product status ensures continued availability and supply chain reliability, and ROHS3 compliance aligns with current environmental and regulatory requirements. The height difference of 0.01mm (2.80mm vs 2.79mm) is within standard PCB assembly tolerances and does not affect board-level compatibility. The Tape & Reel packaging of the substitute is standard for production environments and provides improved handling efficiency compared to bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can the 293D684X9050C2TE3 be used as a direct replacement for the T86C684K050EBAS?

A: Yes. Both parts are manufactured by Vishay Sprague and share identical capacitance (0.68 µF), voltage rating (50 V), tolerance (±10%), ESR (5.9 Ohm), operating temperature range (-55°C ~ 125°C), and package dimensions (2312/6032 Metric). The substitute is electrically and mechanically equivalent.

Q: What is the significance of the product status difference?

A: The T86C684K050EBAS is obsolete, meaning it is no longer manufactured and existing inventory is limited. The 293D684X9050C2TE3 is active, ensuring reliable long-term availability for new designs and production runs.

Q: Does the RoHS3 compliance of the substitute affect compatibility?

A: No. RoHS3 compliance is a manufacturing standard that ensures the substitute meets current environmental regulations. It does not alter electrical performance or physical compatibility with the original part.

Q: Are there any height or dimensional concerns with the substitute?

A: No. The seated height difference of 0.01mm (2.80mm vs 2.79mm) is negligible and falls within standard PCB assembly tolerances. Both parts use the identical 2312 (6032 Metric) package footprint.

Q: What packaging format is the substitute supplied in?

A: The 293D684X9050C2TE3 is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes and provides better handling and storage characteristics than bulk packaging.
