T97F157M025HAA Equivalent & Substitute Parts

Part Overview

The T97F157M025HAA is a 150 µF conformal coated tantalum capacitor manufactured by Vishay Sprague, rated for 25 V operation in a 3024 (7660 Metric) surface mount package. This component is classified as Active product status and is designed for high-reliability applications requiring stable capacitance performance across the operating temperature range of -55°C to 85°C. Substitute parts are identified when equivalent electrical and mechanical parameters are required but the original part becomes unavailable or when alternative compliance certifications are acceptable for the application.

Substitute Part Grouping Explanation

Substitution eligibility for the T97F157M025HAA is determined by the following critical parameters:

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

The identified substitute part T97F157K025LSA meets all critical electrical and mechanical parameters. The primary difference is the capacitance tolerance specification, which varies from ±20% (main part) to ±10% (substitute part). This represents a tighter tolerance specification on the substitute part, making it functionally compatible while offering improved precision.

Parameter Comparison

Engineering Selection Recommendations

Both the T97F157M025HAA and T97F157K025LSA are Active status components from the same manufacturer and series. The main part carries ROHS3 compliance certification, while the substitute part is RoHS non-compliant. Selection between these parts depends on regulatory and compliance requirements for the end application. If RoHS3 compliance is mandatory, the T97F157M025HAA is the required choice. If RoHS compliance is not a constraint, the T97F157K025LSA provides equivalent electrical and mechanical performance with the added benefit of tighter capacitance tolerance (±10% versus ±20%).

Frequently Asked Questions (FAQ)

Q: Can T97F157K025LSA be used as a direct replacement for T97F157M025HAA?

A: Yes, from an electrical and mechanical standpoint. 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 physical dimensions. The substitute part offers tighter tolerance (±10% versus ±20%). However, the substitute part is RoHS non-compliant, which may restrict its use in applications with RoHS compliance requirements.

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

A: Tolerance specifies the allowable deviation of the actual capacitance value from the nominal 150 µF specification. The main part allows deviation up to ±20%, while the substitute allows deviation up to ±10%. The tighter tolerance of the substitute part provides greater precision and predictability in circuit performance, though both parts meet the same electrical specifications for the rated voltage and temperature range.

Q: Are the physical dimensions identical between these parts?

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 the PCB.

Q: What does RoHS compliance mean for component selection?

A: RoHS (Restriction of Hazardous Substances) compliance indicates that the component meets regulatory restrictions on hazardous materials. The main part is ROHS3 compliant, while the substitute is RoHS non-compliant. If your application or end market requires RoHS certification, the main part must be used. If RoHS compliance is not required, both parts are functionally equivalent.

Q: Are both parts currently in stock?

A: Yes. The main part T97F157M025HAA has 1137 pieces in stock, and the substitute T97F157K025LSA has 1269 pieces in stock, both listed as New Original.
