Parameter Comparison

Engineering Selection Recommendations

Both the T97F157K025LBB and T97F157K025LSA are Active product status components manufactured by Vishay Sprague within the TANTAMOUNT™ T97 series. Both parts are RoHS non-compliant and carry identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability, packaging format (both supplied in Tape & Reel), or supply chain logistics. The T97F157K025LSA currently has higher inventory availability (1269 Pcs versus 697 Pcs for the main part number). Both components are suitable for direct substitution in applications requiring 150 µF, 25 V conformal coated tantalum capacitors with 80 mOhm ESR in 3024 surface mount packages.

Frequently Asked Questions (FAQ)

Q: Can T97F157K025LSA be used as a direct replacement for T97F157K025LBB?

A: Yes. Both parts are parametric equivalents with identical capacitance, voltage rating, tolerance, ESR, operating temperature range, package dimensions, and conformal coating specification. They are interchangeable for circuit applications.

Q: Are there any differences in reliability or performance between these parts?

A: No. Both parts carry identical high-reliability ratings, moisture sensitivity levels (2A, 4 Weeks), and operating temperature specifications (-55°C to 85°C).

Q: What is the significance of the different part number suffixes (LBB versus LSA)?

A: The suffix designates internal manufacturing or packaging variations within the Vishay Sprague product line. The electrical and mechanical parameters remain equivalent.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. Both parts use identical 3024 (7660 Metric) surface mount packages with matching footprints, dimensions, and lead spacing. No PCB layout modifications are required.

Q: Are there any compliance or certification differences?

A: Both parts share identical ECCN (EAR99) and HTSUS (8532.21.0050) classifications. Both are RoHS non-compliant. The T97F157K025LSA includes REACH Unaffected status documentation.

Q: What is the maximum operating temperature for these capacitors?

A: Both parts are rated for continuous operation up to 85°C, with a minimum operating temperature of -55°C.
