Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete T520V157M006ASE025 is based on strict electrical and mechanical parameter matching. All substitute parts maintain the following critical parameters:

• Capacitance: 150 µF (±20% tolerance)
• Voltage Rating: 6.3 V
• ESR: 25 mOhm @ 100 kHz
• Package: 2917 (7343 Metric)
• Physical Dimensions: 0.287" L x 0.169" W (7.30 mm x 4.30 mm)
• Height: 0.075" (1.90 mm) maximum seated
• Operating Temperature: -55°C to +105°C
• Lifetime: 2000 Hours @ 105°C
• Mounting: Surface Mount
• MSL Rating: 3 (168 Hours)

Substitute parts differ only in packaging format (Cut Tape, Digi-Reel, or Tape & Reel configurations) and product status (Active vs. Obsolete). Series designation variations (T520 vs. T522) and RoHS compliance improvements are permitted within this substitution group, as these do not affect electrical performance or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: T520V157M006ATE025

This part is the direct functional equivalent of the obsolete T520V157M006ASE025. It maintains identical electrical specifications and mechanical dimensions while offering active product status and ROHS3 compliance. The Cut Tape and Digi-Reel packaging format provides flexibility for both manual assembly and automated production environments.

Secondary Recommendations: T520V157M006ATE025Z160, T520V157M006ATE025Z164, T520V157M006ATE025Z150

These parts are parametrically equivalent to the primary recommendation, differing only in packaging format (Tape & Reel configurations). Selection among these variants depends on production volume and assembly equipment compatibility. T520V157M006ATE025Z160 offers ROHS3 compliance certification.

Alternative Recommendation: T522V157M006ATE025

This part belongs to the KO-CAP® T522 series rather than T520, but maintains all critical electrical and mechanical parameters. It is suitable for applications where series designation flexibility is permitted. ROHS3 compliance and active product status make this a viable long-term alternative.

Frequently Asked Questions (FAQ)

Q: Can T520V157M006ATE025 be used as a direct replacement for T520V157M006ASE025?

A: Yes. Both parts share identical capacitance (150 µF), voltage rating (6.3 V), ESR (25 mOhm @ 100 kHz), package (2917/7343 Metric), and physical dimensions. The primary difference is product status (Active vs. Obsolete) and RoHS compliance improvement.

Q: What is the difference between the packaging formats listed?

A: T520V157M006ATE025 is supplied in Cut Tape (CT) and Digi-Reel® format, suitable for both manual and automated pick-and-place assembly. T520V157M006ATE025Z150, T520V157M006ATE025Z160, and T520V157M006ATE025Z164 are supplied in Tape & Reel (TR) format, optimized for high-volume automated assembly lines. The suffix codes (Z150, Z160, Z164) indicate different reel configurations.

Q: Are there electrical performance differences between T520 and T522 series parts?

A: No. For the specified part numbers, T520V157M006ATE025 and T522V157M006ATE025 are electrically identical. Both deliver 150 µF capacitance, 6.3 V rating, and 25 mOhm ESR. Series designation reflects internal design generation but does not affect performance for this application.

Q: What does ROHS3 compliance mean for this component?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. This certification is relevant for applications subject to environmental regulations in the European Union and similar jurisdictions.

Q: Can I mix different substitute part numbers in the same production batch?

A: Yes, provided the application does not require identical part traceability or specific reel configuration for assembly equipment. All listed substitutes are electrically and mechanically interchangeable.

Q: What is the Moisture Sensitivity Level (MSL) rating, and why does it matter?

A: MSL 3 indicates the component can be stored in dry conditions for up to 168 hours before soldering. Exceeding this time requires baking at specified temperature and humidity conditions before assembly. This is critical for supply chain planning and assembly process control.
