Substitute Part Grouping Explanation

Substitution of the T86C105K050CBAS is determined by strict equivalence across the following parameters: capacitance value (1 µF), tolerance (±10%), voltage rating (50 V), package type (2312/6032 Metric), mounting method (surface mount), and operating temperature range (-55°C to 125°C). All substitute parts must maintain these electrical and mechanical specifications to ensure functional compatibility within the original application circuit.

The two identified substitute parts meet these core requirements while differing in ESR (Equivalent Series Resistance), product status, and compliance certifications. These differences are secondary to the primary substitution criteria and do not affect basic capacitive functionality in standard applications.

Engineering Selection Recommendations

For applications requiring RoHS compliance, the 293D105X9050C2TE3 is the appropriate substitute, as it maintains ROHS3 compliance while meeting all electrical and mechanical specifications of the original T86C105K050CBAS. This part is currently in active production status with adequate inventory availability.

The T83C105K050EZZL offers superior ESR performance (1.6 Ohm versus 4.4 Ohm), which may provide benefits in applications sensitive to impedance characteristics. However, this part is RoHS non-compliant and should be selected only when RoHS compliance is not a system requirement. This part is also in active production status.

Both substitute parts are manufactured by Vishay Sprague and share identical capacitance, voltage rating, tolerance, package dimensions, and operating temperature specifications with the original component. Selection between the two substitutes should be based on compliance requirements and ESR performance needs specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the 293D105X9050C2TE3 be used as a direct replacement for the T86C105K050CBAS?

A: Yes. Both parts share identical capacitance (1 µF), voltage rating (50 V), tolerance (±10%), package type (2312/6032 Metric), and operating temperature range (-55°C to 125°C). The 293D105X9050C2TE3 is electrically and mechanically compatible for direct substitution.

Q: What is the significance of the ESR difference between these parts?

A: ESR (Equivalent Series Resistance) affects impedance at high frequencies. The T86C105K050CBAS has 4.4 Ohm ESR, the 293D105X9050C2TE3 has 4.6 Ohm ESR, and the T83C105K050EZZL has 1.6 Ohm ESR. In most general-purpose applications, these differences are not functionally significant. Applications with stringent ripple current or high-frequency noise filtering requirements may benefit from the lower ESR of the T83C105K050EZZL.

Q: Why is the T86C105K050CBAS obsolete?

A: The part is listed as obsolete by the manufacturer. The active substitute parts (293D105X9050C2TE3 and T83C105K050EZZL) represent current production alternatives from Vishay Sprague's TANTAMOUNT™ series.

Q: Are there packaging differences between these parts?

A: The original T86C105K050CBAS is supplied in bulk packaging. Both substitute parts are supplied in Tape & Reel (TR) format, which is standard for high-volume manufacturing and automated assembly processes.

Q: Which substitute should I select for new designs?

A: For new designs requiring RoHS compliance, select the 293D105X9050C2TE3. For applications where RoHS compliance is not required and lower ESR is beneficial, the T83C105K050EZZL is an option. Both parts are in active production status.
