Substitute Part Grouping Explanation

Substitute parts for the 860160472002 are qualified based on the following criteria:

Identical Capacitance: 15 µF maintained across all substitutes
Identical Tolerance: ±20% maintained across all substitutes
Identical Mechanical Compatibility: Lead spacing (2.00mm), case diameter (5.00mm), height (12.50mm), and through-hole mounting type identical
Identical Thermal Specifications: 4000-hour lifetime at 105°C and operating temperature range (-55°C ~ 105°C) maintained
Identical Polarization and Package: Radial, Can configuration maintained
Identical Compliance: ROHS3 compliant across all parts

Substitutes differ only in Voltage - Rated, which is increased from 25 V to 35 V or 50 V. Higher voltage ratings provide enhanced safety margins in applications where voltage stress may approach or exceed the original specification.

Engineering Selection Recommendations

All three parts—860160472002, 860160572002, and 860160672010—are Active products with ROHS3 compliance and identical mechanical and thermal specifications. Selection between these parts is determined by circuit voltage requirements:

860160472002 (25 V): Use when circuit voltage does not exceed 25 V and cost optimization is prioritized.
860160572002 (35 V): Use when circuit voltage ranges from 26 V to 35 V or when a moderate voltage safety margin above 25 V is required.
860160672010 (50 V): Use when circuit voltage ranges from 36 V to 50 V or when maximum voltage safety margin is required.

All substitutes maintain identical capacitance, tolerance, thermal lifetime, operating temperature range, and physical footprint. Direct PCB substitution is possible without layout modification.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated substitute in place of the original 25 V part?

A: Yes. The 35 V (860160572002) and 50 V (860160672010) substitutes are electrically and mechanically compatible with the 25 V original (860160472002). Higher voltage ratings do not degrade performance in lower-voltage applications and provide additional safety margin.

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

A: Yes. All three parts share identical lead spacing (2.00mm), case diameter (5.00mm), height (12.50mm), and through-hole mounting configuration. No PCB layout changes are required.

Q: Are there differences in ripple current handling between the parts?

A: Yes. The 50 V substitute (860160672010) supports higher ripple current (78 mA @ 120 Hz, 150 mA @ 100 kHz) compared to the 25 V original (62.4 mA @ 120 Hz, 120 mA @ 100 kHz). The 35 V substitute (860160572002) provides intermediate ripple current capability (74.88 mA @ 120 Hz, 144 mA @ 100 kHz).

Q: Do all parts have the same thermal lifetime specification?

A: Yes. All three parts are rated for 4000 hours at 105°C and operate across the identical temperature range of -55°C to 105°C.

Q: Are all parts ROHS3 compliant?

A: Yes. The original part and all substitutes are ROHS3 compliant.
