Substitute Part Grouping Explanation

Substitution eligibility for the T95R156K050ESSL is determined by strict adherence to the following parameters: capacitance value (15 µF), tolerance (±10%), voltage rating (50 V), conformal coating type, package designation (2824 / 7260 Metric), and surface mount mounting configuration. The T95R156K050ESAS qualifies as a parametric equivalent because it maintains identical values across all critical electrical and mechanical specifications. The only variance between these parts is the ESR rating: the main part specifies 350 mOhm while the substitute specifies 400 mOhm. This difference falls within acceptable operational margins for most applications utilizing tantalum capacitors in this category, as both values remain within typical performance envelopes for conformal coated tantalum devices in the T95 series.

Parameter Comparison

Engineering Selection Recommendations

Both T95R156K050ESSL and T95R156K050ESAS are active production components from Vishay Sprague with identical COTS ratings and high reliability designations. Selection between these parts should be based on application-specific ESR requirements. The T95R156K050ESSL with 350 mOhm ESR is suitable for applications requiring lower series resistance characteristics. The T95R156K050ESAS with 400 mOhm ESR remains functionally equivalent for applications where the 50 mOhm difference does not impact circuit performance. Both parts share identical compliance certifications, package dimensions, and thermal operating ranges, ensuring direct mechanical and electrical interchangeability within the specified parameter tolerances.

Frequently Asked Questions (FAQ)

Q: Can T95R156K050ESAS be used as a direct replacement for T95R156K050ESSL?

A: Yes. Both parts are conformal coated tantalum capacitors with identical capacitance (15 µF), voltage rating (50 V), tolerance (±10%), package (2824 / 7260 Metric), and operating temperature range (-55°C to 125°C). The ESR difference of 50 mOhm between the parts does not prevent substitution in applications where this variance is acceptable.

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

A: ESR (Equivalent Series Resistance) affects impedance characteristics and heat dissipation in the capacitor. The T95R156K050ESSL specifies 350 mOhm while the T95R156K050ESAS specifies 400 mOhm. Applications sensitive to ESR performance should confirm that the 400 mOhm specification meets circuit requirements before substitution.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 2824 (7260 Metric) package with dimensions of 0.283" L x 0.236" W (7.20mm x 6.00mm) and maximum seated height of 0.150" (3.80mm). They are mechanically interchangeable on PCB layouts designed for either part.

Q: Do these parts have the same moisture sensitivity requirements?

A: Yes. Both parts carry a Moisture Sensitivity Level (MSL) rating of 2A (4 Weeks), requiring identical handling and storage protocols.

Q: Are there compliance differences between these parts?

A: No. Both parts share identical RoHS status (non-compliant), ECCN classification (EAR99), and HTSUS code (8532.21.0050).
