Substitute Part Grouping Explanation

Substitution eligibility for the BFC236545563 is determined by strict equivalence across the following critical parameters: capacitance value (0.056 µF), tolerance (±10%), dielectric material (polyester metallized), mounting type (through hole radial), physical dimensions (10.00mm x 4.00mm with 13.50mm seated height), lead spacing (5.00mm), and operating temperature range (-55°C to 105°C).

Two substitute parts are identified:

MFR Recommended Substitute - BFC236645563: Maintains identical electrical specifications (0.056 µF, ±10%, 250V DC, 160V AC) and mechanical form factor. Differs only in series designation (MKT366 vs. MKT365) and product status (active vs. obsolete). Packaging is specified as Tape & Box (TB).

Parametric Equivalent - BFC236655563: Maintains identical capacitance (0.056 µF), tolerance (±10%), dielectric material, and mechanical dimensions. Voltage rating is elevated to 400V DC / 220V AC, providing enhanced voltage margin. Series designation is MKT366. Product status is active.
