Frequently Asked Questions (FAQ)

Q: Can BFC237051473 be used as a direct replacement for BFC237055473?

A: Yes. Both parts are parametric equivalents with identical capacitance (0.047 µF), voltage ratings (400V DC / 220V AC), tolerance (±10%), dielectric material (polyester metallized), operating temperature range (-55°C to 105°C), and physical dimensions. They share the same series classification (MKT370) and mounting configuration (through hole radial with 0.200" lead spacing).

Q: Are there any differences in compliance or certification between these parts?

A: No. Both parts carry identical compliance ratings: AEC-Q200 automotive qualification, RoHS3 compliance, and REACH Unaffected status. Both are active production parts with no restrictions on use.

Q: What determines substitutability for this capacitor type?

A: Substitutability is determined by exact equivalence in capacitance value, tolerance, voltage ratings (both AC and DC), dielectric material composition, operating temperature range, mounting type, package configuration, lead spacing, and physical dimensions. All these parameters must match for direct substitution in automotive and industrial applications.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Identical lead spacing (0.200" / 5.08mm), physical dimensions (0.283" L x 0.236" W), and radial package configuration ensure mechanical and electrical interchangeability in through-hole PCB designs without layout modifications.

Q: What is the significance of the MKT370 series designation?

A: MKT370 is the series classification for this polyester metallized film capacitor family from Vishay. Both the main part and substitute share this designation, confirming they belong to the same product line with consistent electrical and thermal characteristics.
