Substitute Part Grouping Explanation

Substitution of the T86C684K050ESSS is determined by strict equivalence across the following parameters:

• Capacitance value: 0.68 µF
• Tolerance: ±10%
• Voltage rating: 50 V
• ESR: 5.9 Ohm
• Package type: 2312 (6032 Metric)
• Physical dimensions: 0.236" L × 0.126" W
• Mounting configuration: Surface Mount
• Operating temperature range: -55°C to 125°C
• Moisture sensitivity: MSL 1

The identified substitute, 293D684X9050C2TE3, meets all these electrical and mechanical parameters. The primary distinction is product status: the original part is obsolete, while the substitute is active in production.

Parameter Comparison

Engineering Selection Recommendations

The 293D684X9050C2TE3 is the direct functional equivalent to the T86C684K050ESSS. Both parts share identical electrical specifications and mechanical form factors. The substitute part is currently in active production status, ensuring supply availability and long-term support.

The 293D684X9050C2TE3 achieves ROHS3 compliance, whereas the original T86C684K050ESSS is non-compliant. For applications subject to RoHS regulations, the substitute part satisfies compliance requirements. The marginal difference in seated height (2.79 mm versus 2.80 mm) is within standard manufacturing tolerances and does not affect circuit board layout or assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 293D684X9050C2TE3 be used as a direct replacement for the T86C684K050ESSS?

A: Yes. Both parts are molded tantalum capacitors with identical capacitance (0.68 µF), voltage rating (50 V), tolerance (±10%), ESR (5.9 Ohm), and package dimensions (2312/6032 Metric). Electrical and mechanical compatibility is complete.

Q: What is the primary reason for substitution?

A: The T86C684K050ESSS is obsolete. The 293D684X9050C2TE3 is an active production part from the same manufacturer, ensuring continued availability and supply chain stability.

Q: Are there any compliance differences between these parts?

A: The 293D684X9050C2TE3 is ROHS3 compliant, while the T86C684K050ESSS is non-compliant. For applications requiring RoHS certification, the substitute part meets regulatory requirements.
