Substitute Part Grouping Explanation

Substitution eligibility for the 860010378020 is determined by the following critical parameters: capacitance value (1800 µF), voltage rating (minimum 16 V), package configuration (radial, can), physical dimensions (lead spacing, diameter, height), and mounting type (through hole). All substitute parts maintain identical capacitance, tolerance, package type, and physical footprint. Variations occur in voltage rating, operating temperature range, and lifetime specifications at elevated temperatures. These variations establish three substitution categories:

Direct Substitutes: Parts with identical electrical and thermal specifications but different series designations.

Voltage Upgrades: Parts with higher voltage ratings (25 V) while maintaining the same capacitance and package.

Lifetime Upgrades: Parts with extended lifetime ratings at elevated temperatures and expanded operating temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can 860020378020 be used as a direct replacement for 860010378020?

A: Yes. Both parts share identical capacitance (1800 µF), voltage rating (16 V), tolerance (±20%), package configuration (radial, can), and physical dimensions. The 860020378020 operates to 105°C versus 85°C for the original part and is rated for 2000 hours at 105°C.

Q: What is the difference between the voltage upgrade option 860010478020 and the original part?

A: The 860010478020 provides a 25 V voltage rating compared to 16 V on the original 860010378020. Both maintain 1800 µF capacitance, identical physical footprint, and 2000-hour lifetime at 85°C. The higher voltage rating provides additional safety margin in circuits subject to voltage transients.

Q: Are the lifetime upgrade parts physically interchangeable?

A: Yes. Parts 860080378023 and 860160378037 maintain identical lead spacing (5.00mm), diameter (13.00mm), and height (21.50mm) as the original 860010378020. Both are through-hole mounted radial capacitors with 1800 µF capacitance and 16 V rating.

Q: What is the operating temperature difference between substitute options?

A: The original 860010378020 operates from -40°C to 85°C. The 860020378020 extends the upper limit to 105°C. The lifetime upgrade parts (860080378023 and 860160378037) expand the range to -55°C to 105°C, providing both lower and upper temperature margin.

Q: Which substitute part offers the longest service life?

A: The 860160378037 provides 7000 hours at 105°C, compared to 5000 hours for 860080378023 and 2000 hours for both the original and other substitutes at their respective temperature ratings.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed parts including the original 860010378020 are ROHS3 compliant and REACH unaffected.
