Substitute Part Grouping Explanation

Substitution for the T520D156M025ASE080 is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance: 15 µF (exact match required)
• Voltage Rating: 25 V (exact match required)
• ESR @ 100 kHz: 80 mOhm (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C to 105°C (exact match required)
• Lifetime @ 105°C: 2000 Hrs (exact match required)
• Tolerance: ±20% (exact match required)
• Moisture Sensitivity Level: 3 (exact match required)

The substitute parts T520D156M025ATE080 and T520D156M025AHE080 meet all these criteria. The primary distinction between these parts lies in packaging format (Tape & Reel) and product status (Active vs. Obsolete), not in electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

T520D156M025ATE080 is the primary recommended substitute. This part is active in production, available in Tape & Reel packaging, and compliant with ROHS3 regulations. It provides identical electrical and mechanical performance to the obsolete T520D156M025ASE080 while offering superior supply chain availability and regulatory compliance for new designs.

T520D156M025AHE080 is an alternative substitute with identical electrical and mechanical specifications. This part is active in production and available in Tape & Reel packaging. However, it does not meet ROHS3 compliance requirements. Selection of this part should be based on specific application requirements and regulatory constraints.

Both substitute parts maintain full compatibility with the original T520D156M025ASE080 in terms of circuit performance, thermal characteristics, and physical footprint.

Frequently Asked Questions (FAQ)

Q: Can T520D156M025ATE080 or T520D156M025AHE080 be used as direct replacements for T520D156M025ASE080?

A: Yes. Both substitute parts are electrically and mechanically equivalent. They share identical capacitance (15 µF), voltage rating (25 V), ESR (80 mOhm @ 100 kHz), package dimensions (2917 / 7343 Metric), and operating temperature range (-55°C to 105°C). They are suitable for direct substitution in existing designs.

Q: What is the difference between the three part numbers?

A: The three parts are functionally identical in electrical and mechanical performance. The differences are: (1) Product Status: T520D156M025ASE080 is obsolete; T520D156M025ATE080 and T520D156M025AHE080 are active. (2) Packaging: T520D156M025ASE080 is supplied in bulk; the substitutes are supplied in Tape & Reel format. (3) RoHS Compliance: T520D156M025ATE080 is ROHS3 compliant; T520D156M025ASE080 and T520D156M025AHE080 are not.

Q: Which substitute should I select for a new design?

A: T520D156M025ATE080 is recommended for new designs due to its active production status and ROHS3 compliance. This ensures long-term supply availability and regulatory alignment with current environmental standards.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. All three parts operate across the same temperature range (-55°C to 105°C), maintain identical ESR characteristics (80 mOhm @ 100 kHz), and provide the same lifetime rating (2000 Hrs @ 105°C).

Q: Can these parts be used interchangeably in automated assembly?

A: T520D156M025ATE080 and T520D156M025AHE080 are both supplied in Tape & Reel packaging, making them suitable for automated pick-and-place assembly. The original T520D156M025ASE080 is supplied in bulk format and requires manual handling.

Q: What is the Moisture Sensitivity Level, and does it affect substitution?

A: All three parts have an MSL rating of 3 (168 Hours), indicating identical moisture sensitivity. This parameter does not differentiate the parts and does not affect substitution decisions.
