Engineering Selection Recommendations

The Rubycon 450BXW82MEFR16X40 is a qualified substitute for the Nichicon UAS2G820MHD in applications where the original part is unavailable. Both components maintain Active product status and full ROHS3 compliance. The substitute part provides enhanced electrical performance characteristics, including higher voltage rating (450 V vs. 400 V), extended lifetime (12000 Hrs vs. 2000 Hrs at 105°C), and increased ripple current handling capability. Mechanical and thermal specifications are identical, ensuring direct board-level compatibility without design modification. Selection between these parts should be based on availability and application-specific performance requirements.

Frequently Asked Questions (FAQ)

Q: Can the Rubycon 450BXW82MEFR16X40 be used as a direct replacement for the Nichicon UAS2G820MHD?

A: Yes. Both parts share identical capacitance (82 µF), tolerance (±20%), operating temperature range (-40°C ~ 105°C), physical dimensions (0.630" Dia × 1.654" Height), lead spacing (0.295"), and mounting configuration (through-hole radial can). The substitute part exceeds the voltage requirement (450 V vs. 400 V) and provides superior lifetime and ripple current ratings.

Q: Are there any mechanical compatibility concerns?

A: No. Both parts are identical in package type (radial, can), physical dimensions, and lead spacing. No PCB layout modifications are required for substitution.

Q: What are the compliance differences between these parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and share identical ECCN (EAR99) and HTSUS (8532.22.0020) classifications. No compliance barriers exist for substitution.

Q: Does the higher voltage rating of the substitute part affect circuit operation?

A: No. A higher voltage-rated capacitor operates safely in circuits designed for lower voltage ratings. The 450 V rating of the substitute part provides additional safety margin in the 400 V application.

Q: What is the significance of the extended lifetime rating?

A: The Rubycon part provides 12000 hours at 105°C compared to 2000 hours for the Nichicon part. This represents a 6× improvement in thermal life expectancy, indicating enhanced reliability in high-temperature operating conditions.
