Substitute Part Grouping Explanation

Substitution for the T95R156M050CSSL is determined by strict equivalence in the following parameters:

• Capacitance value: 15 µF (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)
• Type: Conformal Coated (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Series: TANTAMOUNT™, T95 (exact match required)

Variations permitted within substitution criteria include tolerance (±10% to ±20%) and ESR (350 mOhm to 400 mOhm), provided all other parameters remain identical. The substitute part T95R156K050ESAS meets these criteria.

Parameter Comparison

Engineering Selection Recommendations

The T95R156K050ESAS serves as a parametric equivalent to the T95R156M050CSSL based on matching capacitance, voltage rating, package, and thermal operating range. Both components are Active status products from the same manufacturer series.

The primary distinction between these parts is RoHS compliance status: the main part T95R156M050CSSL is ROHS3 compliant, while the substitute T95R156K050ESAS is RoHS non-compliant. Selection between these parts must be determined by the regulatory and compliance requirements of the end application.

Secondary differences include tolerance specification (±20% versus ±10%) and ESR (350 mOhm versus 400 mOhm). The substitute part offers tighter tolerance control, while the main part provides lower equivalent series resistance. These variations are within acceptable ranges for the 2824 package conformal coated tantalum capacitor category.

Frequently Asked Questions (FAQ)

Q: Can T95R156K050ESAS replace T95R156M050CSSL in all applications?

A: Electrical and mechanical compatibility is maintained. However, RoHS compliance status differs. Verify compliance requirements for your specific application before substitution.

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

A: Tolerance defines the acceptable capacitance variation from the nominal 15 µF value. The substitute part (±10%) provides tighter capacitance control compared to the main part (±20%). Both tolerances are within the conformal coated tantalum capacitor specification for the 2824 package.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical dimensions: 0.283" L x 0.236" W (7.20mm x 6.00mm) with a maximum seated height of 0.150" (3.80mm). They are mechanically interchangeable in the 2824 (7260 Metric) package footprint.

Q: What does the ESR difference (350 mOhm vs. 400 mOhm) mean for circuit performance?

A: ESR affects impedance characteristics and ripple current handling. The main part exhibits lower ESR (350 mOhm), while the substitute exhibits higher ESR (400 mOhm). Circuit design must accommodate the substitute's ESR specification if selected.

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

A: Yes. Both T95R156M050CSSL and T95R156K050ESAS are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
