Substitute Part Grouping Explanation

Substitute parts for the BFC238340823 are identified based on strict electrical and mechanical compatibility criteria. The following parameters must remain constant or be exceeded to ensure functional equivalence:

• Capacitance value: 0.082 µF (exact match required)
• Tolerance: ±5% (exact match required)
• Dielectric material: Polypropylene (PP), Metallized (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Radial (exact match required)
• Physical dimensions and lead spacing (exact match required)
• Operating temperature range: -55°C to 105°C (exact match required)
• Voltage ratings: DC and AC ratings may be equal or higher

The BFC238350823 qualifies as a direct substitute because it maintains identical capacitance, tolerance, dielectric material, mounting configuration, package dimensions, and temperature range while providing higher voltage ratings (1600V DC / 550V AC versus 1400V DC / 500V AC).

Parameter Comparison

Engineering Selection Recommendations

Both the BFC238340823 and BFC238350823 maintain active product status with full ROHS3 compliance and unlimited moisture sensitivity rating. The BFC238350823 provides higher voltage ratings while maintaining identical physical form factor, lead spacing, and electrical characteristics. Selection between these parts depends on circuit voltage requirements: use BFC238340823 where 1400V DC / 500V AC ratings are specified, or use BFC238350823 where higher voltage margins are required or where 1600V DC / 550V AC ratings are specified. Both parts are suitable for high-pulse and DV/DT applications within their respective voltage specifications.
