Engineering Selection Recommendations

Direct Equivalents (2000 Hrs @ 105°C):

UCL1A102MNL1GS (Nichicon), 10TKV1000M10X10.5 (Rubycon), AFK108M10G24T-F (Cornell Dubilier), EEE-FK1A102AL (Panasonic), EEE-FK1A102AP (Panasonic), and EEE-FK1A102P (Panasonic) are direct functional equivalents to the 865080257014. All maintain identical electrical specifications and mechanical compatibility. Selection among these parts is based on inventory availability, packaging preference (Tape & Reel versus Cut Tape & Digi-Reel), and application-specific requirements such as automotive qualification (AEC-Q200 rated parts) or halogen-free designation.

Extended Lifetime Upgrades (5000 Hrs @ 105°C):

865060257010 (Würth Elektronik), 10TLV1000M10X10.5 (Rubycon), and EEE-FK1A102GP (Panasonic) provide extended operational lifetime at elevated temperature. These upgrades are suitable for applications requiring enhanced reliability or longer service intervals. All maintain mechanical compatibility and electrical specifications with the original part.

Automotive Applications:

Parts carrying AEC-Q200 certification (10TKV1000M10X10.5, 10TLV1000M10X10.5, AFK108M10G24T-F, EEE-FK1A102AL, EEE-FK1A102AP, EEE-FK1A102GP, EEE-FK1A102P) are qualified for automotive use. Selection of these parts is appropriate for designs requiring automotive-grade component qualification.

Compliance Considerations:

All listed parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Moisture Sensitivity Level 1 (Unlimited) applies uniformly across all parts, indicating no special moisture handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 865080257014 with a part having different case height?

A: Case height variation between 0.394" (10.00mm) and 0.413" (10.50mm) is acceptable provided all other mechanical and electrical parameters match. The UCL1A102MNL1GS features 0.394" seated height and is mechanically compatible. Verify PCB layout clearance before substitution.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Both packaging formats are compatible for surface mount assembly. Tape & Reel (TR) is supplied on continuous reel suitable for high-volume automated pick-and-place operations. Cut Tape (CT) & Digi-Reel® is supplied in shorter tape lengths with reel compatibility, suitable for lower-volume or mixed-component assembly. Electrical and mechanical specifications are identical between packaging formats.

Q: Are parts with 5000 Hrs lifetime rating backward compatible with designs specified for 2000 Hrs?

A: Yes. Parts rated for 5000 Hrs @ 105°C (865060257010, 10TLV1000M10X10.5, EEE-FK1A102GP) are direct upgrades and fully compatible with designs originally specified for 2000 Hrs lifetime. No design changes are required.

Q: What does AEC-Q200 certification mean?

A: AEC-Q200 is an automotive industry qualification standard for discrete semiconductors and passive components. Parts carrying this certification have undergone stress testing and reliability qualification for automotive applications. Selection of AEC-Q200 rated parts is required for automotive designs; these parts are optional for general purpose applications.

Q: Can I use EEE-FK1C102SP as a substitute?

A: No. EEE-FK1C102SP is rated for 16 V, not 10 V. Voltage rating must match exactly. This part is not compatible with designs specified for 10 V operation.

Q: What is the significance of impedance and ripple current differences?

A: Impedance and ripple current are performance characteristics that vary by manufacturer design. Lower impedance and higher ripple current capability indicate improved high-frequency performance. Parts with lower impedance (60 mOhms to 80 mOhms) compared to the original 150 mOhms offer enhanced performance in switching applications. Verify that your circuit design does not impose specific ripple current or impedance requirements before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
