Engineering Selection Recommendations

Direct Replacement (Identical Electrical Performance):

T520D107M010ATE080 is the direct functional equivalent to B76010V1079M080. Both components share identical capacitance (100 µF), voltage rating (10 V), and ESR specification (80 mOhm @ 100 kHz). The T520D107M010ATE080 is active production status with 2000 Hrs @ 105°C lifetime rating, providing superior supply chain availability compared to the obsolete B76010V1079M080. Physical height differs (3.10 mm vs. 2.00 mm), requiring PCB layout verification.

Lower ESR Alternatives (Same Voltage Rating):

For applications where reduced ESR improves performance, the following active alternatives maintain 10 V rating with lower impedance:

T520V107M010ATE050 (50 mOhm): Height 1.90 mm
T520V107M010ATE045 (45 mOhm): Height 1.90 mm
T520W107M010ATE040 (40 mOhm): Height 1.50 mm
T520V107M010ATE025 (25 mOhm): Height 1.90 mm
T520V107M010ATE018 (18 mOhm): Height 1.90 mm

Higher Voltage Rating Alternative:

T521V107M016ATE050 provides 16 V rating with 50 mOhm ESR and extended operating temperature to 125°C. This part is suitable for applications requiring voltage derating margin or higher temperature operation. Height remains 2.00 mm, matching the original component.

All substitute parts maintain ROHS3 compliance, MSL 3 rating, and 2917 package footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can T520D107M010ATE080 directly replace B76010V1079M080 without PCB modification?

A: Electrical substitution is direct. However, the seated height increases from 2.00 mm to 3.10 mm. PCB clearance above the component must be verified to prevent mechanical interference with adjacent components or enclosure constraints.

Q: What is the advantage of selecting lower ESR alternatives like T520V107M010ATE018?

A: Lower ESR reduces impedance at operating frequencies, improving transient response and reducing voltage ripple. Selection depends on circuit requirements. The 18 mOhm variant also provides reduced height (1.90 mm), offering better PCB density.

Q: Is T521V107M016ATE050 compatible with 10 V circuit designs?

A: Yes. The 16 V rating provides voltage derating margin for 10 V applications. This part is suitable when higher voltage tolerance or extended temperature operation (-55°C to 125°C vs. -55°C to 105°C) is beneficial. Electrical performance is compatible with 10 V circuit specifications.

Q: What is the difference between Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) packaging?

A: Both are surface mount packaging formats. Cut Tape is supplied in smaller quantities on tape; Tape & Reel is supplied in larger reel quantities for automated assembly. Electrical and mechanical specifications are identical. Selection depends on procurement volume and assembly process requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 3 (168 Hours) rating, matching the original B76010V1079M080 environmental and regulatory specifications.

Q: Why do T520 series parts show 2000 Hrs @ 105°C lifetime while B76010V1079M080 does not specify lifetime?

A: The B76010V1079M080 is obsolete product with incomplete technical documentation. Active KO-CAP® T520 and T521 series parts include verified lifetime ratings, providing design confidence for long-term reliability calculations.

Q: Can multiple ESR variants be mixed in the same circuit?

A: Yes, provided circuit design accommodates the impedance variation range (18 mOhm to 80 mOhm). Mixing variants is acceptable for general purpose applications. Critical filtering or transient suppression circuits should use consistent ESR specifications across all capacitors in the filter network.
