T95R156M050ESSL Equivalent & Substitute Parts

Part Overview

The T95R156M050ESSL is a 15 µF conformal coated tantalum capacitor manufactured by Vishay Sprague, rated for 50 V operation in the 2824 (7260 Metric) surface mount package. This component is part of the TANTAMOUNT™ T95 series and maintains Active product status. Tantalum capacitors of this specification are essential in applications requiring high volumetric efficiency, stable capacitance across temperature ranges, and reliable performance in demanding environments. Alternative models may be required due to inventory constraints, specific tolerance requirements, or ESR (Equivalent Series Resistance) specifications for particular circuit designs.

Substitute Part Grouping Explanation

Substitution eligibility for the T95R156M050ESSL is determined by strict adherence to the following parameters:

• Capacitance Value: Must be 15 µF (no deviation permitted)
• Voltage Rating: Must be 50 V or higher
• Package / Case: Must be 2824 (7260 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount
• Type: Must be Conformal Coated
• Operating Temperature Range: Must support -55°C ~ 125°C minimum
• Moisture Sensitivity Level: Must be 2A or better

The substitute part T95R156K050ESAS meets all mandatory substitution criteria. The primary difference between the main part and its substitute is the tolerance specification (±20% versus ±10%) and ESR rating (350 mOhm versus 400 mOhm). Both components share identical capacitance, voltage rating, package, and thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the T95R156M050ESSL and T95R156K050ESAS are Active products from Vishay Sprague with identical compliance certifications (ECCN: EAR99, HTSUS: 8532.21.0050) and RoHS status. Selection between these components should be based on tolerance and ESR requirements specific to the application circuit.

The T95R156M050ESSL offers lower ESR (350 mOhm) with ±20% tolerance, suitable for applications where ESR minimization is prioritized. The T95R156K050ESAS provides tighter capacitance tolerance (±10%) with slightly higher ESR (400 mOhm), appropriate for circuits requiring precise capacitance values. Both components maintain identical thermal performance, package dimensions, and moisture sensitivity ratings, ensuring direct mechanical and thermal compatibility on PCB assemblies.

Frequently Asked Questions (FAQ)

Q: Can T95R156K050ESAS replace T95R156M050ESSL in any application?

A: Direct substitution is mechanically and electrically feasible due to identical package dimensions, voltage rating, and thermal range. However, circuit-specific requirements regarding tolerance and ESR must be evaluated. The substitute part offers tighter tolerance (±10% versus ±20%) but with slightly higher ESR (400 mOhm versus 350 mOhm).

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components use the 2824 (7260 Metric) package with identical dimensions: 0.283" L x 0.236" W (7.20mm x 6.00mm) and maximum seated height of 0.150" (3.80mm). PCB footprints and assembly processes remain unchanged.

Q: What is the significance of the tolerance difference?

A: The T95R156M050ESSL specifies ±20% tolerance, while the T95R156K050ESAS specifies ±10% tolerance. Applications requiring precise capacitance values within a narrower band should use the ±10% part. Applications with broader tolerance margins can use either component.

Q: How do ESR differences affect circuit performance?

A: ESR (Equivalent Series Resistance) impacts ripple current handling and voltage drop characteristics. The T95R156M050ESSL at 350 mOhm provides lower ESR compared to the T95R156K050ESAS at 400 mOhm. High-frequency or high-ripple-current applications may benefit from the lower ESR specification.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both components operate across -55°C ~ 125°C, ensuring identical thermal performance and reliability across the full temperature spectrum.

Q: What is the moisture sensitivity implication?

A: Both parts carry MSL 2A (4 Weeks) rating, indicating identical moisture sensitivity. Storage and handling procedures remain consistent between the two components.
