Substitute Part Grouping Explanation

Substitute parts for the R46KF222000N0K are identified based on strict parameter equivalence in the following categories:

Primary Substitution Criteria:

Capacitance value: 0.022 µF (exact match required)
Tolerance: ±10% (exact match required)
Dielectric material: Polypropylene (PP), Metallized (exact match required)
Operating temperature range: -40°C ~ 110°C (exact match required)
Mounting type: Through Hole (exact match required)
Package type: Radial (exact match required)
Physical dimensions: 0.512" L x 0.157" W / 13.00mm x 4.00mm (exact match required)
Lead spacing: 0.394" (10.00mm) (exact match required)
Ratings classification: X2 (exact match required)

Secondary Substitution Criteria (Voltage Rating): Substitute parts may have equal or higher voltage ratings (DC and AC) than the main part, provided all other parameters remain identical. Higher voltage ratings do not affect circuit compatibility in applications requiring lower voltage specifications.

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory conformance. Selection between R46KF222000N0K and R46KF222050N0K is determined by lead spacing tolerance requirements, as both share identical electrical and mechanical specifications. Selection between 560V-rated parts (R46KF series) and 630V-rated parts (R463F series) is determined by circuit voltage requirements; 630V-rated parts provide additional voltage margin and are suitable for applications requiring higher voltage headroom.
