Key Parameters

Substitute Part Grouping Explanation

Substitution of the T86C684M050ESAS is determined by strict equivalence across the following critical parameters:

Capacitance value of 0.68 µF with ±20% tolerance ensures functional compatibility in the circuit application. Voltage rating of 50 V must be maintained to ensure safe operation under specified electrical stress. ESR of 5.9 Ohm is a defining characteristic for this component class and must remain constant. Operating temperature range of -55°C to 125°C establishes the thermal envelope for reliable operation. Surface mount configuration with 2312 (6032 Metric) package ensures mechanical and electrical compatibility with existing PCB layouts. Physical dimensions and height specifications confirm fit within board assembly constraints.

The substitute part 293D684X0050C2TE3 meets all these criteria, providing direct functional and mechanical equivalence while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 293D684X0050C2TE3 serves as the direct substitute for the obsolete T86C684M050ESAS. Both components are manufactured by Vishay Sprague and maintain identical electrical and mechanical specifications across all critical parameters. The substitute part offers two significant advantages: active product status ensures ongoing availability and supply chain continuity, and ROHS3 compliance aligns with current environmental and regulatory requirements. The negligible difference in seated height (2.79mm versus 2.80mm) falls within standard PCB assembly tolerances and presents no compatibility concerns. Selection of the 293D684X0050C2TE3 is appropriate for new designs, redesigns, and field replacements where regulatory compliance and long-term availability are considerations.

Frequently Asked Questions (FAQ)

Q: Can the 293D684X0050C2TE3 be used as a direct replacement for the T86C684M050ESAS in existing assemblies?

A: Yes. Both parts share identical capacitance, voltage rating, ESR, operating temperature range, and package dimensions. The 2312 (6032 Metric) package footprint is identical, and the seated height difference of 0.01mm is within standard assembly tolerances.

Q: What is the significance of the product status change from Obsolete to Active?

A: Active status indicates the 293D684X0050C2TE3 is in current production with established supply channels. This ensures component availability for procurement and reduces risk of future obsolescence.

Q: Does the RoHS3 compliance of the substitute part affect electrical performance?

A: No. RoHS3 compliance reflects manufacturing process and material composition standards. Electrical characteristics, including capacitance, voltage rating, and ESR, remain unchanged and fully compatible with the original design.

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

A: Both parts operate across the identical temperature range of -55°C to 125°C and maintain the same ESR specification of 5.9 Ohm. Reliability characteristics are equivalent for both components.

Q: What packaging formats are available for the 293D684X0050C2TE3?

A: The substitute part is available in Tape & Reel (TR) packaging, consistent with the original component's surface mount application requirements.
