Parameter Comparison

Engineering Selection Recommendations

The ECE-A1VN101U is classified as an active product with full availability, addressing the obsolescence status of the SN101M016ST. Both components maintain ROHS3 compliance and satisfy all mechanical compatibility requirements for direct PCB substitution without layout modifications.

The ECE-A1VN101U provides extended thermal lifetime (2000 hours at 85°C versus 1000 hours), elevated voltage rating (35 V versus 16 V), and higher ripple current capability (230 mA @ 120 Hz versus 205 mA). These characteristics provide improved performance margins in the target application while maintaining identical electrical and mechanical interfaces.

Frequently Asked Questions (FAQ)

Q: Can the ECE-A1VN101U be used as a direct replacement for the SN101M016ST? A: Yes. Both components share identical capacitance (100 µF), tolerance (±20%), lead spacing (5.00 mm), physical dimensions (10.00 mm diameter, 16.00 mm height), mounting type (Through Hole Radial, Can), and operating temperature range (-40°C ~ 85°C). The ECE-A1VN101U possesses superior electrical characteristics including higher voltage rating and extended thermal lifetime.

Q: What is the voltage rating difference between these parts? A: The SN101M016ST is rated at 16 V, while the ECE-A1VN101U is rated at 35 V. A higher voltage rating provides increased operational margin and does not negatively impact circuit performance when the applied voltage does not exceed the original specification.

Q: Are there differences in ripple current handling? A: The ECE-A1VN101U is rated for 230 mA @ 120 Hz, compared to 205 mA @ 120 Hz for the SN101M016ST. The substitute part maintains superior ripple current capability at all frequency ranges.

Q: What is the thermal lifetime difference? A: The SN101M016ST provides 1000 hours @ 85°C, while the ECE-A1VN101U provides 2000 hours @ 85°C. Extended thermal lifetime indicates superior long-term reliability in elevated temperature environments.

Q: Do both components meet the same regulatory standards? A: Yes. Both the SN101M016ST and ECE-A1VN101U maintain ROHS3 compliance status.

Q: Are there any mechanical packaging differences? A: No. Both components share identical lead spacing (5.00 mm), case diameter (10.00 mm), and seated height (16.00 mm), ensuring compatibility with existing PCB footprints and through-hole mounting patterns without modification.
