Parameter Comparison

Engineering Selection Recommendations

Both parts maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory conformance. The 860020381030 substitute provides extended thermal performance with operation to 105°C compared to the 85°C rating of the main part, while maintaining identical mechanical footprint and electrical specifications. Selection between these parts depends on application thermal requirements and ripple current handling capacity at the operating frequency of the circuit.

Frequently Asked Questions (FAQ)

Q: Can the 860020381030 be used as a direct replacement for the 860010381030?

A: Yes. Both parts share identical capacitance (12000 µF), voltage rating (16 V), tolerance (±20%), polarization, package type (Radial, Can), and mechanical dimensions (lead spacing, case diameter, height). The substitute is mechanically and electrically compatible for through-hole PCB mounting.

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

A: The substitute part (860020381030) is rated for operation at higher temperatures, with a thermal rating of 2000 hours at 105°C and an operating range to 105°C, compared to the main part's 85°C specifications. The substitute also operates from the WCAP-ATG5 series versus the WCAP-ATG8 series.

Q: Are there ripple current differences I should consider?

A: Yes. The main part (860010381030) has higher ripple current ratings: 3.058 A @ 120 Hz and 3.91424 A @ 100 kHz. The substitute (860020381030) has lower ripple current ratings: 2.15 A @ 120 Hz and 2.752 A @ 100 kHz. Circuit design must account for the ripple current capability of the selected part at the operating frequency.

Q: Are both parts available in the same packaging?

A: Yes. Both parts are supplied in Cut Tape (CT) packaging and are suitable for automated assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8532.22.0020.
