Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for tantalum capacitors is determined by matching the following critical parameters: capacitance value (15 µF), voltage rating (50 V), package configuration (2824), ESR specification (400 mOhm), operating temperature range (-55°C to 125°C), and conformal coating type. The T95R156K050ESAS qualifies as a parametric equivalent because it maintains identical values across all these core electrical and mechanical specifications. The tolerance rating differs between the main part (±20%) and the substitute (±10%), representing a tighter tolerance specification that does not prevent substitution in applications where the main part is acceptable.

Parameter Comparison

Engineering Selection Recommendations

Both the T95R156M050CSAS and T95R156K050ESAS are Active status components suitable for COTS applications. The T95R156M050CSAS carries RoHS3 compliance certification, while the T95R156K050ESAS is RoHS non-compliant. Selection between these parts should be based on regulatory requirements specific to the end application. The T95R156K050ESAS offers tighter capacitance tolerance (±10% versus ±20%), which may provide performance advantages in applications with strict tolerance requirements. Both parts maintain identical electrical characteristics, physical dimensions, and thermal operating ranges, ensuring direct functional interchangeability at the circuit level.

Frequently Asked Questions (FAQ)

Q: Can T95R156K050ESAS replace T95R156M050CSAS in all applications?

A: Both parts are electrically and mechanically equivalent with identical capacitance, voltage rating, ESR, package dimensions, and operating temperature range. Substitution is valid from a functional standpoint. However, RoHS compliance status differs; verify regulatory requirements for your specific application before substitution.

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 a narrower range (14.6 µF to 16.5 µF) compared to the ±20% range (12 µF to 18 µF) of the main part. Applications requiring tighter capacitance accuracy benefit from the substitute part's specification.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts 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 require no modification.

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 specification, requiring identical moisture control procedures during handling and assembly.

Q: Are there inventory considerations for substitution?

A: The T95R156M050CSAS has 799 pieces in stock, while the T95R156K050ESAS has 1532 pieces available. Substitute part selection may be driven by inventory availability and lead time requirements.
