Substitute Part Grouping Explanation

Substitute parts for the BFC237520121 are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution criteria include:

• Identical capacitance value: 120 pF
• Identical tolerance: ±5%
• Identical voltage ratings: 1000V DC and 400V AC
• Identical dielectric material: Polypropylene (PP), Metallized
• Identical operating temperature range: -55°C ~ 105°C
• Identical mounting type: Through Hole Radial
• Identical lead spacing: 0.394" (10.00mm)
• Identical series designation: KP/MKP 375
• Identical compliance certifications: ROHS3 Compliant, REACH Unaffected

Parts meeting all these criteria are considered direct parametric equivalents within the same manufacturer family and may be used interchangeably in circuit applications.
