Substitute Part Grouping Explanation

Substitution of the 860010678021 is determined by electrical and thermal compatibility. All substitute parts maintain identical capacitance (560 µF), voltage rating (50 V), tolerance (±20%), and physical dimensions (lead spacing, case diameter, height). The primary differentiators are thermal performance characteristics and operating temperature ranges.

The substitute parts are grouped as follows:

Direct Equivalent: Part 860020678023 maintains the same electrical specifications with an extended operating temperature range (-40°C to 105°C versus -40°C to 85°C) and improved thermal lifetime (2000 hours at 105°C).

Upgrade Options: Parts 860080678020 and 860160678031 provide enhanced thermal performance with extended lifetimes (5000 and 7000 hours at 105°C respectively) and wider operating temperature ranges (-55°C to 105°C).

Engineering Selection Recommendations

Selection among these parts is based on application thermal requirements and compliance needs. All substitute parts are Active status and ROHS3 compliant, meeting regulatory requirements equivalent to the main part.

For applications operating within -40°C to 85°C with standard thermal conditions, the 860010678021 is appropriate. For applications requiring extended temperature operation to 105°C or improved thermal stability, the 860020678023 provides direct substitution with enhanced thermal performance at identical physical dimensions.

For applications demanding extended operational lifetime or wider temperature ranges (-55°C to 105°C), the 860080678020 (5000 hours at 105°C) and 860160678031 (7000 hours at 105°C) are upgrade options. These parts maintain identical electrical specifications and physical footprints while providing superior thermal endurance.

Frequently Asked Questions (FAQ)

Q: Can 860020678023 be used as a direct replacement for 860010678021?

A: Yes. Both parts share identical capacitance (560 µF), voltage rating (50 V), tolerance (±20%), and physical dimensions (lead spacing, case diameter, height). The 860020678023 extends the operating temperature range to 105°C and provides thermal lifetime at 105°C, making it a compatible direct substitute.

Q: What is the primary difference between the upgrade parts 860080678020 and 860160678031?

A: Both upgrade parts extend the operating temperature range to -55°C to 105°C. The primary difference is thermal lifetime: 860080678020 provides 5000 hours at 105°C, while 860160678031 provides 7000 hours at 105°C. Physical dimensions and electrical specifications remain identical.
