Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the T322B474K050AS are qualified based on the following critical parameters that determine functional and mechanical interchangeability:

Electrical Parameters:

• Capacitance: 0.47 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating: 50 V (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

Mechanical Parameters:

• Package Type: Axial (exact match required)
• Mounting Type: Through Hole (exact match required)
• Physical Dimensions: 0.110" Dia x 0.290" L / 2.79mm x 7.37mm (exact match required)
• Component Type: Molded Tantalum Capacitor (exact match required)

Substitute parts are grouped into two categories: Direct manufacturer substitutes from KEMET and equivalent cross-manufacturer alternatives from Vishay Sprague. All substitutes maintain identical electrical specifications and physical form factors, ensuring drop-in compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

T322B474K050AT (KEMET Direct Substitute): This part is a direct KEMET substitute with identical electrical and mechanical specifications to the T322B474K050AS. The primary distinction is RoHS3 compliance status. The T322B474K050AT is ROHS3 Compliant, whereas the original part is RoHS non-compliant. Selection of this substitute is appropriate for applications requiring RoHS3 compliance or when KEMET T322 series inventory from the same manufacturer is preferred. Both parts maintain identical capacitance, voltage rating, tolerance, operating temperature range, and physical dimensions.

173D474X9050VE3 (Vishay Sprague Cross-Manufacturer Substitute): This part provides cross-manufacturer equivalence from Vishay Sprague's TANTALEX™ 173D series. Electrical specifications match the original part exactly: 0.47 µF capacitance, ±10% tolerance, 50 V rating, and -55°C to 125°C operating temperature. Physical dimensions and axial through-hole mounting are identical. This substitute is ROHS3 Compliant and REACH Unaffected. The packaging format differs (Cut Tape versus Bulk), which may affect procurement and handling workflows. ESR specification is not provided for this part. Selection is appropriate when Vishay Sprague component availability or supply chain diversification is required.

Frequently Asked Questions (FAQ)

Q: Can T322B474K050AT be used as a direct replacement for T322B474K050AS?

A: Yes. Both parts are KEMET T322 series molded tantalum capacitors with identical electrical specifications (0.47 µF, ±10%, 50 V) and physical dimensions (0.110" Dia x 0.290" L). The primary difference is RoHS compliance status. The T322B474K050AT is ROHS3 Compliant, while the T322B474K050AS is RoHS non-compliant. Mechanical and electrical interchangeability is complete.

Q: Is the Vishay Sprague 173D474X9050VE3 electrically equivalent to the KEMET T322B474K050AS?

A: Yes. The 173D474X9050VE3 matches all critical electrical parameters: 0.47 µF capacitance, ±10% tolerance, 50 V voltage rating, and -55°C to 125°C operating temperature range. Physical dimensions and axial through-hole mounting are identical. Both are molded tantalum capacitors rated for general-purpose applications.

Q: What is the difference in packaging between these substitutes?

A: The KEMET parts (T322B474K050AS and T322B474K050AT) are supplied in Bulk packaging. The Vishay Sprague 173D474X9050VE3 is supplied in Cut Tape (CT) packaging. This affects order quantities, handling, and automated assembly compatibility but does not impact electrical or mechanical performance.

Q: Are all three parts RoHS compliant?

A: No. The T322B474K050AS is RoHS non-compliant. Both the T322B474K050AT and 173D474X9050VE3 are ROHS3 Compliant. Applications requiring RoHS compliance must use either the KEMET T322B474K050AT or the Vishay Sprague 173D474X9050VE3.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, for through-hole assembly applications. All three parts are axial through-hole components with identical physical dimensions (0.110" Dia x 0.290" L). They are mechanically and electrically interchangeable in circuit designs. Packaging format (Bulk versus Cut Tape) may affect assembly line compatibility depending on equipment configuration.

Q: What is the significance of ESR specification?

A: ESR (Equivalent Series Resistance) affects high-frequency performance and ripple current handling. The KEMET parts specify 13 Ohm ESR. The Vishay Sprague 173D474X9050VE3 does not provide ESR specification in the available data. For applications where ESR is a critical design parameter, the KEMET parts provide documented performance characteristics.

Q: Are REACH and ECCN classifications identical across all three parts?

A: Yes. All three parts share identical REACH Status (REACH Unaffected) and ECCN classification (EAR99), indicating equivalent regulatory treatment for export and environmental compliance purposes.
