Substitute Part Grouping Explanation

Substitution of the T86C474M050ESAS is determined by strict equivalence across the following parameters:

• Capacitance Value: Must be 0.47 µF (no deviation)
• Voltage Rating: Must be 50 V or higher
• Package / Case: Must be 2312 (6032 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount
• ESR: Must be 6.7 Ohm to maintain circuit performance characteristics
• Operating Temperature Range: Must support -55°C to 125°C
• Component Type: Must be Molded Tantalum

The substitute part 293D474X9050C2TE3 meets all these criteria. The primary difference is a tighter tolerance specification (±10% versus ±20%), which represents an improvement in precision without affecting functional compatibility.

Engineering Selection Recommendations

The 293D474X9050C2TE3 is the direct substitute for the obsolete T86C474M050ESAS. Selection of this substitute is supported by the following factors:

• Product Status: The substitute is Active, ensuring long-term availability and supply chain stability, whereas the original part is Obsolete.
• Regulatory Compliance: The substitute is ROHS3 Compliant, meeting current environmental and regulatory requirements. The original part is RoHS non-compliant.
• Electrical Equivalence: Both parts share identical capacitance (0.47 µF), voltage rating (50 V), ESR (6.7 Ohm), and operating temperature range (-55°C to 125°C).
• Mechanical Compatibility: Both parts use the 2312 (6032 Metric) surface mount package with equivalent physical dimensions and height specifications.
• Tolerance Improvement: The substitute offers ±10% tolerance compared to the original ±20%, providing tighter capacitance accuracy without introducing incompatibility.

Frequently Asked Questions (FAQ)

Q: Can the 293D474X9050C2TE3 be used as a direct replacement for the T86C474M050ESAS?

A: Yes. Both parts are 0.47 µF molded tantalum capacitors with 50 V ratings, 6.7 Ohm ESR, identical package dimensions (2312/6032 Metric), and matching operating temperature ranges (-55°C to 125°C). The substitute is electrically and mechanically compatible.

Q: What is the primary difference between these two parts?

A: The main differences are product status and compliance. The T86C474M050ESAS is obsolete and RoHS non-compliant, while the 293D474X9050C2TE3 is active and ROHS3 compliant. Additionally, the substitute has a tighter tolerance specification (±10% versus ±20%).

Q: Will the tighter tolerance of the substitute part affect circuit performance?

A: No. A tighter tolerance (±10%) is a specification improvement that does not negatively affect compatibility. Circuits designed for the original ±20% tolerance will operate within specification with the ±10% substitute.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 2312 (6032 Metric) package with dimensions of 0.236" L x 0.126" W (6.00mm x 3.20mm). Maximum seated heights are 0.110" (2.80mm) for the original and 0.110" (2.79mm) for the substitute, representing negligible difference.

Q: Is the substitute part available in the same packaging format?

A: The substitute (293D474X9050C2TE3) is supplied in Tape & Reel (TR) packaging, which is standard for production environments. Verify packaging requirements for your specific application.

Q: What is the moisture sensitivity level for both parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
