Key Parameters

Substitute Part Grouping Explanation

The BFC238350203 qualifies as a direct substitute based on the following alignment of critical parameters:

• Identical capacitance value: 0.02 µF
• Identical tolerance: ±5%
• Identical dielectric material: Polypropylene (PP), Metallized
• Identical mounting type: Through Hole, Radial
• Identical physical dimensions: 26.00mm x 7.00mm, 16.50mm height, 22.50mm lead spacing
• Identical termination: PC Pins
• Identical series: MMKP383
• Identical operating temperature range: -55°C ~ 105°C
• Identical RoHS compliance: ROHS3 Compliant
• Identical MSL rating: 1 (Unlimited)

The substitute part features higher voltage ratings (1600V DC / 550V AC versus 1400V DC / 500V AC), which represents an uprated specification within the same product family. This higher voltage rating does not compromise compatibility in applications designed for the original part's voltage specifications.

Parameter Comparison

Engineering Selection Recommendations

Both BFC238340203 and BFC238350203 are active production parts with ROHS3 compliance and MSL 1 rating, indicating full regulatory alignment and unlimited moisture sensitivity protection. The substitute part BFC238350203 maintains identical electrical and mechanical specifications with the exception of higher voltage ratings. Selection between these parts depends on the application's voltage requirements: use BFC238340203 for circuits designed to 1400V DC / 500V AC specifications, or use BFC238350203 where higher voltage margin is required or preferred. Both parts are suitable for high-pulse and DV/DT applications within their respective voltage ratings.
