Substitute Part Grouping Explanation

Substitution for the T97F157M025ESA is determined by strict equivalence in the following parameters:

• Capacitance value: 150 µF (exact match required)
• Voltage rating: 25 V (exact match required)
• Package / Case: 3024 (7660 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Type: Conformal Coated (exact match required)
• ESR: 80 mOhm (exact match required)
• Operating temperature range: -55°C to 85°C (exact match required)
• Moisture Sensitivity Level: 2A (4 Weeks) (exact match required)

The T97F157K025LSA qualifies as a parametric equivalent substitute. This part maintains all critical electrical and mechanical parameters identical to the main part, with the exception of capacitance tolerance, which is tightened from ±20% to ±10%.

Parameter Comparison

Engineering Selection Recommendations

Both the T97F157M025ESA and T97F157K025LSA maintain Active product status and identical compliance classifications (RoHS non-compliant, ECCN EAR99, HTSUS 8532.21.0050). The substitute part T97F157K025LSA provides tighter capacitance tolerance (±10% versus ±20%), which may be advantageous in applications requiring stricter capacitance accuracy. All other electrical and mechanical specifications remain equivalent. Selection between these parts should be based on tolerance requirements specific to the application circuit design.

Frequently Asked Questions (FAQ)

Q: Can T97F157K025LSA be used as a direct replacement for T97F157M025ESA?

A: Yes. Both parts share identical capacitance (150 µF), voltage rating (25 V), package (3024), ESR (80 mOhm), operating temperature range (-55°C to 85°C), and all mechanical dimensions. The substitute part features improved capacitance tolerance (±10% versus ±20%).

Q: What is the difference between these two parts?
