Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment and supply continuity. The 860160272001 is suitable for applications with 10 V maximum voltage requirements. The 860160372003 provides a 16 V rating with marginally improved ripple current handling, appropriate for circuits requiring moderate voltage headroom. The 860160472003 offers the highest voltage rating at 25 V with substantially increased ripple current capacity and lowest impedance, suitable for high-current or high-voltage margin applications.

Physical compatibility is maintained across all three parts due to identical lead spacing, case dimensions, and height specifications, enabling direct board-level substitution without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the 860160372003 or 860160472003 be used as a direct replacement for the 860160272001?

A: Yes. Both substitute parts maintain identical capacitance (22 µF), tolerance (±20%), operating temperature range (-55°C ~ 105°C), lifetime rating (4000 Hrs @ 105°C), and physical dimensions. Lead spacing, case diameter, and height are identical, enabling direct through-hole board substitution.

Q: What is the primary difference between these three parts?

A: The voltage rating and ripple current handling differ. The 860160272001 is rated at 10 V with 34.32 mA ripple current @ 120 Hz. The 860160372003 is rated at 16 V with 37.44 mA ripple current @ 120 Hz. The 860160472003 is rated at 25 V with 74.88 mA ripple current @ 120 Hz. Impedance decreases with higher voltage ratings.

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: No. All three parts share identical lead spacing (0.079" / 2.00 mm), case diameter (0.197" / 5.00 mm), and maximum seated height (0.492" / 12.50 mm). PCB footprints and mounting holes are interchangeable.

Q: Which substitute part should be selected for a circuit originally designed for the 860160272001?

A: Selection depends on circuit voltage requirements. If the circuit operates below 10 V, the 860160272001 is appropriate. If voltage margins are desired or the circuit operates between 10 V and 16 V, the 860160372003 is suitable. If the circuit operates between 16 V and 25 V, or if high ripple current handling is required, the 860160472003 is appropriate.

Q: Do all three parts have the same thermal and operational characteristics?

A: Yes. All three parts operate across -55°C ~ 105°C and maintain 4000 hours lifetime at 105°C. Operating temperature range and thermal performance are identical.

Q: Are there compliance or regulatory differences between these parts?

A: No. All three parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. Regulatory status is identical across all three parts.
