Substitute Part Grouping Explanation

Substitution eligibility for the T97F157M025CSA is determined by the following criteria:

• Capacitance Value: Must be 150 µF
• Voltage Rating: Must be 25 V or higher
• Package / Case: Must be 3024 (7660 Metric)
• Mounting Type: Must be Surface Mount
• Type: Must be Conformal Coated
• Series: TANTAMOUNT™ T97
• ESR: Must be 80 mOhm
• Operating Temperature Range: Must support -55°C to 85°C

The substitute part T97F157K025LSA meets all mechanical and electrical compatibility requirements. The primary difference is the capacitance tolerance specification, which is tighter (±10%) compared to the main part (±20%).

Parameter Comparison

Engineering Selection Recommendations

Both T97F157M025CSA and T97F157K025LSA are Active status products from the same manufacturer and series. The T97F157M025CSA is RoHS3 Compliant, while the T97F157K025LSA is RoHS non-compliant. Selection between these parts depends on regulatory compliance requirements for the end application.

The T97F157K025LSA offers improved capacitance tolerance (±10% versus ±20%), which may provide tighter performance margins in applications requiring stricter capacitance specifications. Both parts share identical electrical characteristics (150 µF, 25 V, 80 mOhm ESR) and mechanical compatibility (3024 package, surface mount, conformal coated).

Frequently Asked Questions (FAQ)

Q: Can T97F157K025LSA be used as a direct replacement for T97F157M025CSA?

A: Yes, from an electrical and mechanical standpoint. Both parts have identical capacitance (150 µF), voltage rating (25 V), ESR (80 mOhm), package dimensions (3024), and operating temperature range (-55°C to 85°C). The primary difference is capacitance tolerance and RoHS compliance status.

Q: What is the difference in capacitance tolerance between these parts?

A: T97F157M025CSA has ±20% tolerance, while T97F157K025LSA has ±10% tolerance. The tighter tolerance of the substitute part may be beneficial in precision applications but is not required for basic functional equivalence.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 3024 (7660 Metric) package with dimensions of 0.299" L x 0.236" W (7.60mm x 6.00mm) and maximum seated height of 0.201" (5.10mm). They are mechanically interchangeable on PCBs designed for either part.

Q: What is the RoHS compliance difference?

A: T97F157M025CSA is RoHS3 Compliant, while T97F157K025LSA is RoHS non-compliant. Applications subject to RoHS regulations must use the T97F157M025CSA or verify alternative compliant sources.

Q: Are both parts conformal coated?

A: Yes. Both T97F157M025CSA and T97F157K025LSA are conformal coated tantalum capacitors, providing the same environmental protection characteristics.
