Substitute Part Grouping Explanation

Substitute parts for the BFC246729392 are identified based on strict parametric equivalence within the MKT467 series. Substitution is valid when the following criteria are met: identical capacitance value (3900 pF), matching tolerance (±5%), equivalent voltage ratings (400V DC / 220V AC), identical dielectric material (polyester, metallized), matching operating temperature range (-55°C ~ 105°C), identical mounting configuration (through-hole radial), matching physical dimensions and lead spacing (0.394" / 10.00mm), and equivalent compliance certifications (ROHS3). All substitute parts listed maintain the same electrical performance envelope and mechanical compatibility for direct board-level replacement.

Parameter Comparison

Engineering Selection Recommendations

Both BFC246729392 and BFC246756392 maintain Active product status and identical compliance certifications (ROHS3 Compliant, REACH Unaffected). Selection between these parts is determined by inventory availability and supply chain considerations rather than electrical or mechanical performance differences. The BFC246756392 offers higher inventory availability (2507 pcs vs. 739 pcs), making it suitable for high-volume production requirements. Both parts are suitable for applications requiring 3900 pF capacitance at 400V DC operation with polyester dielectric construction.
