Engineering Selection Recommendations

All three parts—860160272006, 860160372008, and 860160472008—share identical product status (Active), compliance certifications (ROHS3 Compliant, REACH Unaffected), and mechanical compatibility. Selection between these parts depends solely on circuit voltage requirements.

The 860160272006 (10 V) is appropriate for applications with maximum operating voltages at or below 10 V. The 860160372008 (16 V) and 860160472008 (25 V) provide increased voltage headroom and are suitable for circuits where higher safety margins or transient voltage protection are required. Both substitute parts maintain the same form factor and thermal characteristics, ensuring direct PCB compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can I use the 860160372008 (16 V) or 860160472008 (25 V) in place of the 860160272006 (10 V)?

A: Yes. Both substitute parts are mechanically and electrically compatible. They feature identical capacitance (56 µF), tolerance (±20%), physical dimensions, lead spacing, and thermal ratings. The higher voltage ratings provide additional design margin without affecting circuit board layout or mounting requirements.

Q: Will the substitute parts fit the same PCB footprint?

A: Yes. All three parts share identical lead spacing (0.079" / 2.00mm), diameter (0.197" / 5.00mm), and maximum seated height (0.492" / 12.50mm). No PCB redesign is necessary.

Q: Are there any performance differences between the main part and substitutes?

A: The substitute parts exhibit lower impedance and higher ripple current ratings due to their higher voltage ratings. These characteristics improve performance in high-frequency applications and under ripple current stress. Capacitance and tolerance remain identical across all three parts.

Q: Do all parts meet the same compliance standards?

A: Yes. The 860160272006, 860160372008, and 860160472008 are all ROHS3 compliant and REACH unaffected, ensuring equivalent regulatory compliance for industrial and commercial applications.

Q: What is the difference in ripple current handling?

A: The 860160472008 (25 V) handles 137.28 mA at 120 Hz and 264 mA at 100 kHz, compared to 74.88 mA and 144 mA respectively for the 860160272006 (10 V). Higher ripple current capability in substitute parts allows operation in more demanding electrical environments.
