Engineering Selection Recommendations

860020473009 (Direct Substitute): This part maintains identical electrical specifications and physical dimensions as the main part. It extends the maximum operating temperature to 105°C and provides equivalent 2000-hour lifetime at this elevated temperature. Selection is appropriate when designs require operation in higher ambient temperature environments while maintaining the same form factor and electrical performance.

860160473012 (Upgrade Substitute): This part provides extended operational temperature range (-55°C to 105°C) and doubled lifetime rating (4000 hours at 105°C). It delivers superior ripple current handling at high frequency (402 mA @ 100 kHz). Selection is appropriate for applications demanding enhanced reliability, extended service life, or operation across wider temperature extremes. All parts maintain ROHS3 compliance and Active product status.

Frequently Asked Questions (FAQ)

Q: Can 860020473009 be used as a direct replacement for 860010473008?

A: Yes. Both parts share identical capacitance (120 µF), voltage rating (25 V), tolerance (±20%), and physical dimensions. The substitute extends maximum operating temperature to 105°C and provides 2000-hour lifetime at this temperature, making it suitable for higher-temperature applications.

Q: What is the primary advantage of 860160473012 over the main part?

A: The 860160473012 offers extended lifetime (4000 hours at 105°C versus 2000 hours at 85°C) and wider operating temperature range (-55°C to 105°C). It also provides higher ripple current capacity at 100 kHz (402 mA versus 349.14 mA), beneficial for high-frequency switching applications.

Q: Are all three parts physically interchangeable?

A: Yes. All three parts share identical lead spacing (0.098" / 2.50 mm), diameter (0.248" / 6.30 mm), and height (0.492" / 12.50 mm). They are mechanically interchangeable in through-hole PCB designs.

Q: Do substitute parts maintain the same compliance certifications?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and classified as Active products. They share identical ECCN (EAR99) and HTSUS (8532.22.0020) classifications.

Q: Which substitute should be selected for maximum reliability?

A: The 860160473012 provides the highest reliability metrics with 4000-hour lifetime at 105°C and extended temperature range. Selection depends on specific application requirements for temperature extremes and service life expectations.
