T95R156K050CSAL Equivalent & Substitute Parts

Part Overview

The T95R156K050CSAL is a 15 µF conformal coated tantalum capacitor rated for 50 V operation in a 2824 (7260 Metric) surface mount package. Manufactured by Vishay Sprague under the TANTAMOUNT™ T95 series, this component is actively produced and widely used in high-reliability applications requiring stable capacitance performance across extended temperature ranges. Substitute parts are identified when inventory constraints, lead time requirements, or specific compliance certifications necessitate alternative sourcing while maintaining functional equivalence.

Substitute Part Grouping Explanation

Substitution eligibility for the T95R156K050CSAL is determined by strict equivalence across the following parameters:

• Capacitance value: 15 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage rating: 50 V (exact match required)
• Package / Case: 2824 (7260 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)
• Conformal coating: Required for environmental protection

The identified substitute part T95R156K050ESAS meets all core electrical and mechanical parameters. Variations in ESR (Equivalent Series Resistance) and RoHS compliance status are secondary characteristics that do not affect functional substitutability in applications where the primary electrical specifications are met.

Parameter Comparison

Engineering Selection Recommendations

Both T95R156K050CSAL and T95R156K050ESAS are active production components from Vishay Sprague's TANTAMOUNT™ T95 series with identical electrical and mechanical specifications. Selection between these parts depends on regulatory and compliance requirements:

The T95R156K050CSAL is ROHS3 compliant and is the preferred choice for applications subject to RoHS directives or customer specifications requiring RoHS certification.

The T95R156K050ESAS is RoHS non-compliant and is suitable for applications without RoHS requirements. This part carries a marginally higher ESR specification (400 mOhm versus 350 mOhm), which remains within acceptable limits for standard circuit applications.

Both parts are conformal coated, rated for -55°C to 125°C operation, and packaged identically in the 2824 (7260 Metric) surface mount format. Inventory availability and lead time considerations may also influence part selection.

Frequently Asked Questions (FAQ)

Q: Can T95R156K050ESAS be used as a direct replacement for T95R156K050CSAL?

A: Yes, from an electrical and mechanical standpoint. Both parts share identical capacitance (15 µF), voltage rating (50 V), tolerance (±10%), package (2824), and operating temperature range (-55°C to 125°C). The primary difference is RoHS compliance status. Verify your application's compliance requirements before substitution.

Q: What is the significance of the ESR difference between these parts?

A: The T95R156K050CSAL specifies 350 mOhm ESR while the T95R156K050ESAS specifies 400 mOhm ESR. This 50 mOhm difference is minor and does not affect functional compatibility in standard applications. Applications with stringent ESR requirements should specify the lower-ESR variant.

Q: Are both parts available in the same packaging format?

A: Yes. Both the T95R156K050CSAL and T95R156K050ESAS are supplied in Tape & Reel (TR) packaging and are mounted identically in the 2824 (7260 Metric) surface mount package with matching physical dimensions and height specifications.

Q: What does "Conformal Coated" mean for these capacitors?

A: Conformal coating is a protective polymer layer applied to the capacitor to provide environmental protection against moisture, dust, and corrosive atmospheres. Both substitute parts include this coating, making them suitable for harsh operating environments.

Q: Which part should I select for a new design?

A: If your application or customer requirements mandate RoHS compliance, select T95R156K050CSAL. If RoHS compliance is not required and cost or availability is a consideration, T95R156K050ESAS is functionally equivalent. Both parts are actively produced and carry high-reliability ratings suitable for demanding applications.
