Key Parameters

Substitute Part Grouping Explanation

Substitution of the T495X475M050ASE300 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 4.7 µF (exact match required)
• Voltage Rating: 50 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR: 300 mOhm (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Type: Molded Tantalum (exact match required)

The substitute parts identified below meet all mandatory matching parameters. Variations in physical height, manufacturer size codes, and product status (active vs. obsolete) do not affect functional equivalence when all electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

TR3D475M050C0300 (Vishay Sprague): This substitute part is functionally equivalent to the T495X475M050ASE300 across all critical electrical and mechanical parameters. The TR3D475M050C0300 is classified as active product status, ensuring ongoing availability and supply chain support. This part carries RoHS3 compliance certification, providing regulatory advantage over the non-compliant original part. The seated height of 0.122" (3.10 mm) is lower than the original specification, which may provide layout benefits in space-constrained applications. Packaging is supplied as Tape & Reel (TR).

TR3E475M050C0300 (Vishay Sprague): This substitute part is functionally equivalent to the T495X475M050ASE300 across all critical electrical and mechanical parameters. The TR3E475M050C0300 is classified as active product status, ensuring ongoing availability and supply chain support. This part carries RoHS3 compliance certification, providing regulatory advantage over the non-compliant original part. The seated height of 0.170" (4.32 mm) closely matches the original specification of 0.169" (4.30 mm), providing the most direct physical compatibility. Packaging is supplied as Tape & Reel (TR).

Both substitute parts from Vishay Sprague meet all mandatory electrical and mechanical equivalence criteria. Selection between TR3D475M050C0300 and TR3E475M050C0300 depends on specific board layout constraints and height clearance requirements.

Frequently Asked Questions (FAQ)

Q: What makes TR3D475M050C0300 and TR3E475M050C0300 suitable substitutes for T495X475M050ASE300?

A: Both Vishay Sprague parts match the T495X475M050ASE300 across all critical parameters: 4.7 µF capacitance, ±20% tolerance, 50 V voltage rating, 300 mOhm ESR, 2917 (7343 Metric) package, surface mount configuration, and -55°C to 125°C operating temperature range. These parameters define functional equivalence for molded tantalum capacitors in this category.

Q: Are there differences in physical dimensions between the substitute parts and the original?

A: Yes. The TR3D475M050C0300 has a maximum seated height of 0.122" (3.10 mm), which is lower than the original T495X475M050ASE300 at 0.169" (4.30 mm). The TR3E475M050C0300 has a maximum seated height of 0.170" (4.32 mm), which closely matches the original. Both parts maintain the same length and width dimensions of 0.287" L x 0.169" W (7.30 mm x 4.30 mm). Height differences must be evaluated against specific board layout and clearance requirements.

Q: What is the significance of RoHS compliance in these substitutes?

A: The original T495X475M050ASE300 is RoHS non-compliant, while both substitute parts (TR3D475M050C0300 and TR3E475M050C0300) are RoHS3 compliant. RoHS3 compliance indicates conformance to current environmental and hazardous substance restrictions. For applications subject to regulatory requirements or customer specifications mandating RoHS compliance, the Vishay Sprague substitutes provide regulatory alignment.

Q: Can these parts be used interchangeably in existing designs?

A: TR3D475M050C0300 and TR3E475M050C0300 are electrically and mechanically equivalent to T495X475M050ASE300 for all specified parameters. Interchangeability depends on board layout constraints. The TR3E475M050C0300, with its height of 0.170" (4.32 mm), provides the closest physical match to the original 0.169" (4.30 mm) specification. The TR3D475M050C0300, with its lower height of 0.122" (3.10 mm), may require verification of clearance in designs with tight vertical spacing.

Q: Why is the original part classified as obsolete?

A: The T495X475M050ASE300 is listed as obsolete by KEMET. This classification indicates the part is no longer in active production. Identifying active substitute parts ensures continued access to equivalent functionality and supports long-term supply chain planning for systems utilizing this capacitor specification.

Q: What packaging formats are available for the substitute parts?

A: Both TR3D475M050C0300 and TR3E475M050C0300 are supplied in Tape & Reel (TR) packaging format, which is standard for surface mount component distribution and automated assembly processes.
