Substitute Part Grouping Explanation

Substitution of the T86C105M050ESSL is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance value: 1 µF (exact match required)
• Voltage rating: 50 V (minimum acceptable)
• Package / Case: 2312 (6032 Metric) (physical and electrical compatibility)
• Mounting type: Surface Mount (assembly compatibility)
• Operating temperature range: -55°C to 125°C (functional compatibility)
• Moisture sensitivity level: 1 (Unlimited) (handling and storage compatibility)

The TPSC105K050R2500 from KYOCERA AVX meets all substitution criteria. While tolerance differs (±10% versus ±20%), this represents an improvement in specification. The ESR value of 2.5 Ohm is lower than the original 2.7 Ohm, which is acceptable for circuit performance. Both parts are molded tantalum capacitors in identical physical packages with matching electrical ratings.

Engineering Selection Recommendations

The TPSC105K050R2500 is the direct substitute for the T86C105M050ESSL. Selection is based on the following factors:

• Electrical equivalence: Both parts share identical capacitance, voltage rating, and operating temperature specifications
• Physical compatibility: Identical 2312 (6032 Metric) package ensures direct board-level replacement without layout modification
• Improved tolerance: The ±10% tolerance of the substitute provides tighter capacitance control compared to the original ±20% specification
• Lower ESR: The 2.5 Ohm ESR of the substitute is lower than the original 2.7 Ohm, which is beneficial for circuit performance
• Active product status: The substitute is in active production, ensuring long-term availability and supply chain stability
• Compliance improvement: The substitute meets ROHS3 compliance, whereas the original is RoHS non-compliant

Frequently Asked Questions (FAQ)

Q: Can the TPSC105K050R2500 be used as a direct replacement for the T86C105M050ESSL?

A: Yes. Both parts are 1 µF, 50 V molded tantalum capacitors in the 2312 (6032 Metric) package with identical operating temperature ranges and moisture sensitivity levels. No circuit modifications or board layout changes are required.

Q: What is the significance of the tolerance difference between ±20% and ±10%?

A: The substitute part has a tighter tolerance specification, meaning its actual capacitance value will be closer to the nominal 1 µF rating. This is an improvement over the original part and does not create compatibility issues.

Q: Does the lower ESR of the substitute part affect circuit performance?

A: The substitute part has an ESR of 2.5 Ohm compared to the original 2.7 Ohm. Lower ESR is generally beneficial for circuit performance, particularly in applications sensitive to impedance characteristics. This change does not create compatibility concerns.

Q: Are there any compliance or regulatory differences between these parts?

A: The substitute part (TPSC105K050R2500) is ROHS3 compliant, while the original part (T86C105M050ESSL) is RoHS non-compliant. Both parts are REACH Unaffected and classified as EAR99 for export control purposes.

Q: What is the availability status of each part?

A: The original T86C105M050ESSL is obsolete and has limited inventory (765 pieces). The substitute TPSC105K050R2500 is in active production with significantly higher availability (25,400 pieces in stock).
