Key Parameters

Substitute Part Grouping Explanation

Substitution of the T520V686M010ASE045 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 68 µF (exact match required)
• Voltage Rating: 10 V (exact match required)
• ESR Specification: 45 mOhm @ 100 kHz (exact match required)
• Package Format: 2917 (7343 Metric) (exact match required)
• Physical Dimensions: 0.287" L × 0.169" W × 0.075" H maximum (exact match required)
• Operating Temperature Range: -55°C to 105°C (exact match required)
• Lifetime Rating: 2000 Hours @ 105°C (exact match required)
• Mounting Type: Surface Mount (exact match required)

Substitute parts must satisfy all parameters listed above without deviation. The primary distinction between the main part and its substitute relates to product status and packaging configuration, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The T520V686M010ATE045 is the direct equivalent substitute for the obsolete T520V686M010ASE045. Both components are manufactured by KEMET within the KO-CAP® T520 series and share identical electrical and mechanical specifications.

The T520V686M010ATE045 is recommended for new designs and ongoing production applications due to its active product status. This part maintains full compatibility with the original specification while offering improved supply chain availability.

The T520V686M010ATE045 carries RoHS3 compliance certification, whereas the original part is RoHS non-compliant. Both components maintain REACH Unaffected status and EAR99 export classification.

The primary operational difference is packaging configuration: the substitute is supplied in Tape & Reel (TR) format, which is standard for high-volume manufacturing environments. This packaging change does not affect component performance or board-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can the T520V686M010ATE045 be used as a direct replacement for the T520V686M010ASE045?

A: Yes. Both components are electrically and mechanically identical. They share the same capacitance value (68 µF), voltage rating (10 V), ESR specification (45 mOhm @ 100 kHz), package format (2917 / 7343 Metric), and operating characteristics. The substitute is suitable for direct board-level replacement.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and packaging format. The T520V686M010ASE045 is obsolete and supplied in standard packaging. The T520V686M010ATE045 is an active product supplied in Tape & Reel (TR) format. The T520V686M010ATE045 also carries RoHS3 compliance certification.

Q: Are there any physical dimension differences between these parts?

A: No. Both components are housed in the 2917 (7343 Metric) package with identical dimensions: 0.287" L × 0.169" W × 0.075" H maximum. They are mechanically interchangeable on printed circuit boards.

Q: Does the Tape & Reel packaging affect component performance?

A: No. Tape & Reel packaging is a delivery and handling format only. It does not alter the electrical performance, reliability, or operating characteristics of the capacitor. The component itself is identical to standard packaging variants.

Q: Are there any compliance or certification differences?

A: The T520V686M010ATE045 carries RoHS3 compliance certification, while the original part is RoHS non-compliant. Both components maintain REACH Unaffected status. For applications requiring RoHS compliance, the substitute is the appropriate selection.

Q: What is the inventory status of these parts?

A: The T520V686M010ASE045 (obsolete) has 921 pieces in stock. The T520V686M010ATE045 (active) has 2100 pieces in stock, providing superior supply chain availability for ongoing production requirements.
