Substitute Part Grouping Explanation

Substitution of the T86C474K050EBAS is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance value: 0.47 µF
• Tolerance: ±10%
• Voltage rating: 50 V
• ESR: 6.7 Ohm
• Package type: 2312 (6032 Metric)
• Mounting configuration: Surface Mount
• Operating temperature range: -55°C to 125°C
• Physical dimensions and height compatibility

The substitute part 293D474X9050C2TE3 meets all these criteria and is therefore classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 293D474X9050C2TE3 is the direct equivalent substitute for the obsolete T86C474K050EBAS. Both parts share identical electrical specifications and mechanical compatibility. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The 293D474X9050C2TE3 offers improved compliance status, meeting ROHS3 requirements compared to the non-compliant original part. This makes it the preferred choice for new designs and ongoing production requiring regulatory compliance. The substitute is supplied in Tape & Reel packaging, suitable for automated assembly processes.

Physical dimensions are equivalent with negligible height variation (2.80mm vs 2.79mm seated height), confirming PCB layout compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 293D474X9050C2TE3 be used as a direct replacement for the T86C474K050EBAS?

A: Yes. Both parts are 0.47 µF, 50 V molded tantalum capacitors in the 2312 (6032 Metric) package with identical ESR and operating temperature specifications. Physical dimensions are equivalent, confirming PCB footprint compatibility.

Q: What is the primary reason for substitution?

A: The T86C474K050EBAS is obsolete. The 293D474X9050C2TE3 is an active production equivalent that maintains all electrical and mechanical specifications while providing improved regulatory compliance.

Q: Are there packaging differences between these parts?

A: Yes. The original part is supplied in bulk packaging, while the substitute is supplied in Tape & Reel (TR) format. This difference does not affect electrical performance or PCB compatibility; it only impacts procurement and assembly logistics.

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS compliance is a regulatory and environmental requirement, not an electrical performance specification. Both parts function identically in circuit applications. The ROHS3 compliance of the substitute makes it suitable for applications requiring regulatory adherence.

Q: Are the physical dimensions identical?

A: Dimensions are equivalent for PCB layout purposes. Seated height differs by 0.01mm (2.80mm vs 2.79mm), which is within standard manufacturing tolerance and does not require design modification.
