Key Parameters

Substitute Part Grouping Explanation

Substitution of the T86C474M050EBAS is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance value: 0.47 µF
• Tolerance: ±20%
• Rated voltage: 50 V
• Equivalent series resistance: 6.7 Ohm
• Package type: 2312 (6032 Metric)
• Operating temperature range: -55°C to 125°C
• Mounting configuration: Surface mount

The 293D474X0050C2TE3 meets all these criteria and is classified as a direct equivalent. This substitute maintains identical electrical performance and physical compatibility while offering the advantage of active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 293D474X0050C2TE3 is the direct equivalent substitute for the obsolete T86C474M050EBAS. Both components are manufactured by Vishay Sprague and share identical electrical specifications and physical dimensions within tolerance. The substitute part offers two significant advantages: active product status ensuring continued availability, and ROHS3 compliance compared to the non-compliant status of the original part. The height difference of 0.01mm (2.80mm versus 2.79mm) is within standard manufacturing tolerances and does not affect circuit board layout or assembly compatibility. The substitute is supplied in Tape & Reel packaging, which is standard for production environments.

Frequently Asked Questions (FAQ)

Q: Can the 293D474X0050C2TE3 be used as a direct replacement for the T86C474M050EBAS?

A: Yes. Both parts are molded tantalum capacitors with identical capacitance (0.47 µF), voltage rating (50 V), tolerance (±20%), ESR (6.7 Ohm), operating temperature range (-55°C to 125°C), and package dimensions (2312/6032 Metric). Physical height differs by 0.01mm, which is within standard manufacturing tolerance and does not affect PCB assembly.

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

A: The T86C474M050EBAS is obsolete, meaning it is no longer manufactured and existing inventory will eventually deplete. The 293D474X0050C2TE3 is active, ensuring long-term availability for production and field service applications.

Q: Does the RoHS compliance difference affect substitution?

A: The 293D474X0050C2TE3 is ROHS3 compliant while the T86C474M050EBAS is non-compliant. For applications subject to RoHS regulations or customer requirements, the substitute part provides compliance. For legacy systems without such requirements, both parts are electrically equivalent.

Q: Are there packaging considerations for the substitute part?

A: The substitute is supplied in Tape & Reel (TR) packaging, which is standard for automated assembly. The original part was supplied in bulk packaging. TR packaging is compatible with standard pick-and-place equipment and does not affect component performance.

Q: What parameters must remain constant for substitution to be valid?

A: Capacitance value, voltage rating, tolerance, ESR, operating temperature range, and package type must all match. The 293D474X0050C2TE3 maintains all these parameters, making it a valid substitute.
