Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4590-225K is determined by equivalence across the following critical parameters:

Inductance value and tolerance must match exactly at 2.2 mH ±10%. Current rating and saturation current specifications must be identical or exceed the original part ratings of 615 mA and 380 mA respectively. DC resistance must not exceed 1.76 Ohm maximum. Core material composition must remain ferrite with unshielded configuration. Mounting type and package style must be through-hole axial to ensure mechanical and electrical compatibility. Physical dimensions must conform to the specified 0.455" diameter by 0.900" length envelope. Operating temperature range must span -55°C to 125°C minimum. All substitute parts must be from the same manufacturer series to ensure design consistency.

The 4590R-225K qualifies as a direct substitute based on complete parameter equivalence across all electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The 4590R-225K provides direct substitution for the 4590-225K with identical electrical and mechanical performance. The primary distinction between these parts is regulatory compliance status. The 4590-225K is RoHS non-compliant, while the 4590R-225K achieves ROHS3 compliance. Both parts maintain REACH Unaffected status and share the same ECCN (EAR99) and HTSUS (8504.50.4000) classifications.

Selection between these parts should be based on application regulatory requirements. Applications requiring RoHS3 compliance mandate use of the 4590R-225K. Applications without RoHS compliance constraints may utilize either part. The 4590R-225K currently maintains higher inventory availability at 2075 pieces compared to 916 pieces for the 4590-225K.
