Key Parameters

Substitute Part Grouping Explanation

Substitution of tantalum capacitors is determined by strict equivalence in the following parameters:

• Capacitance value (15 µF)
• Voltage rating (50 V minimum)
• Package / Case (2824 / 7260 Metric)
• Conformal coating type
• Operating temperature range (-55°C to 125°C)
• Surface mount mounting type
• Moisture sensitivity classification (2A)

The substitute part T95R156K050ESAS maintains all critical mechanical and electrical parameters. The tolerance specification differs (±10% versus ±20%), and ESR increases from 350 mOhm to 400 mOhm. These variations remain within acceptable substitution criteria for tantalum capacitor applications where the primary functional requirements are capacitance value, voltage rating, and package compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the T95R156M050LSSL and T95R156K050ESAS are Active status components from the same manufacturer series. Selection between these parts is based on application-specific requirements:

The T95R156M050LSSL offers a tighter tolerance specification (±20%) with lower ESR (350 mOhm), suitable for applications where capacitance stability and low impedance are prioritized.

The T95R156K050ESAS provides improved tolerance (±10%) with slightly elevated ESR (400 mOhm), appropriate for applications where capacitance accuracy is critical.

Both components share identical mechanical compatibility, thermal operating range, and moisture sensitivity classification. Neither component is RoHS compliant. Selection should be based on circuit requirements for capacitance tolerance and ESR performance.

Frequently Asked Questions (FAQ)

Q: Can T95R156K050ESAS replace T95R156M050LSSL in existing designs?

A: Yes, provided the circuit design accommodates the tolerance and ESR differences. The substitute maintains identical capacitance value, voltage rating, package dimensions, and thermal operating range.

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

A: Tolerance specifies the allowable deviation from the nominal 15 µF capacitance value. The ±10% tolerance of the substitute part provides tighter capacitance accuracy, which may be required in precision analog circuits. The ±20% tolerance of the main part allows broader manufacturing variation.

Q: Does the ESR increase from 350 mOhm to 400 mOhm affect circuit performance?

A: ESR impacts impedance characteristics and power dissipation. The 50 mOhm increase represents approximately 14% higher ESR. Applications sensitive to impedance at specific frequencies or requiring minimal power loss should evaluate this parameter against circuit requirements.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components use the 2824 (7260 Metric) package with identical length (0.283" / 7.20mm), width (0.236" / 6.00mm), and maximum seated height (0.150" / 3.80mm). PCB layout and assembly processes are interchangeable.

Q: What does Moisture Sensitivity Level 2A mean?

A: MSL 2A indicates the component can be stored in dry conditions for up to 4 weeks before soldering. Both parts share this classification and require identical moisture control during handling and assembly.
