Engineering Selection Recommendations

All three parts—BFC233922104, BFC233820104, and BFC233920104—are active production components with full ROHS3 compliance and REACH unaffected status. Selection between these parts is determined by application-specific certification requirements and series preference.

The BFC233922104 and BFC233920104 both carry AEC-Q200 automotive qualification and are suitable for automotive applications requiring enhanced reliability standards. The BFC233820104, from the MKP338 series, does not list AEC-Q200 certification but maintains equivalent electrical and mechanical specifications for general EMI/RFI suppression applications.

All three parts are mechanically and electrically interchangeable in through-hole PCB designs with 10.00mm lead spacing and standard radial mounting footprints. Selection should be based on application requirements for automotive-grade certification and current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can BFC233820104 replace BFC233922104 in automotive applications?

A: BFC233820104 is electrically and mechanically equivalent but lacks AEC-Q200 automotive certification. Use only in non-automotive applications or where automotive qualification is not required.

Q: Are all three parts mechanically interchangeable?

A: Yes. All three parts share identical physical dimensions (12.50mm x 6.00mm), lead spacing (10.00mm), and radial through-hole mounting configuration. PCB footprints are directly compatible.

Q: What is the difference between MKP338 and MKP339 series?

A: Both series provide 0.1 µF film capacitors at 630V DC with identical electrical performance and mechanical form factors. Series designation reflects internal manufacturing or design revision; electrical substitution is direct.

Q: Are moisture sensitivity considerations different between these parts?

A: BFC233922104 and BFC233920104 list MSL as Not Applicable. BFC233820104 specifies MSL 1 (Unlimited). All three are suitable for standard PCB assembly processes without special moisture control requirements.

Q: Which part should be selected for new designs?

A: For automotive applications, select BFC233922104 or BFC233920104 (both AEC-Q200 qualified). For general industrial EMI/RFI suppression, any of the three parts are suitable based on availability and cost considerations.
