Substitute Part Grouping Explanation

Substitution of the T86C155M050EBAS is determined by strict equivalence across the following parameters:

• Capacitance value: 1.5 µF
• Tolerance: ±20%
• Voltage rating: 50 V
• Package / Case: 2312 (6032 Metric)
• Mounting type: Surface Mount
• Operating temperature range: -55°C to 125°C
• Moisture sensitivity level: MSL 1

The TAJC155M050SNJ from KYOCERA AVX meets all these criteria and qualifies as a direct substitute. Both parts share identical electrical specifications, physical dimensions, and environmental ratings. The substitute part maintains the same capacitance, voltage rating, tolerance, and thermal operating range required for circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

The TAJC155M050SNJ is suitable as a substitute for the obsolete T86C155M050EBAS based on the following factors:

• Both parts are electrically equivalent with identical capacitance, voltage rating, and tolerance specifications
• Physical dimensions and package footprint are identical, ensuring direct PCB compatibility
• Operating temperature ranges are identical, supporting the same thermal environment requirements
• The substitute part is currently in active production status, ensuring long-term availability
• KYOCERA AVX TAJC155M050SNJ is RoHS3 compliant, providing improved environmental compliance compared to the non-compliant original part
• ESR of the substitute (4.5 Ohm) is lower than the original (5 Ohm), which is favorable for circuit performance

Frequently Asked Questions (FAQ)

Q: Can TAJC155M050SNJ be used as a direct replacement for T86C155M050EBAS?

A: Yes. Both parts share identical electrical specifications (1.5 µF, ±20%, 50 V), physical dimensions (2312 package), and operating temperature range (-55°C to 125°C). The substitute is pin-compatible and footprint-compatible for direct PCB substitution.

Q: What is the difference in ESR between these parts?

A: The original T86C155M050EBAS has an ESR of 5 Ohm, while the substitute TAJC155M050SNJ has an ESR of 4.5 Ohm. The lower ESR of the substitute part is electrically favorable and does not create compatibility issues.

Q: Are there compliance differences between the original and substitute?

A: Yes. The T86C155M050EBAS is RoHS non-compliant, while the TAJC155M050SNJ is RoHS3 compliant. For new designs or production requiring RoHS compliance, the substitute part is the appropriate choice.

Q: Will the substitute part fit the existing PCB layout?

A: Yes. Both parts use the identical 2312 (6032 Metric) surface mount package with matching dimensions of 0.236" L x 0.126" W and a maximum seated height of 0.110". No PCB layout modifications are required.

Q: Is the substitute part currently available?

A: Yes. The TAJC155M050SNJ is in active production status with current inventory availability, unlike the obsolete original part.
