Equivalent & Substitute Parts for API Delevan Inc. 4590-106K Inductor

Part Overview

The API Delevan Inc. 4590-106K is a 10 mH fixed wirewound inductor with a drum core design, rated for 300 mA continuous current and featuring a maximum DC resistance of 7.3 ohms. This unshielded axial-mount component operates across the industrial temperature range of -55°C to 125°C and is specified as Active in product status. Alternative models become necessary when RoHS compliance is required for new designs or when inventory constraints necessitate sourcing from alternative manufacturing batches within the same product family.

Substitute Part Grouping Explanation

The 4590R-106K qualifies as a direct substitute for the 4590-106K based on electrical and mechanical parameter equivalence. Both components share identical specifications across all critical parameters: 10 mH inductance at ±10% tolerance, 300 mA current rating, 180 mA saturation current, 7.3 ohm maximum DC resistance, ferrite drum core construction, unshielded design, through-hole axial mounting, and matching physical dimensions of 0.455" diameter by 0.900" length. The determining factors for substitution eligibility are: inductance value match, current rating match, DC resistance match, core material match, shielding configuration match, and mechanical compatibility through identical package dimensions.

The key distinguishing factor between these parts is regulatory compliance status: the 4590-106K is RoHS non-compliant, while the 4590R-106K achieves ROHS3 compliance. Both components maintain REACH Unaffected and EAR99 ECCN classifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 4590-106K and 4590R-106K are Active status components suitable for new design implementation. Selection between these parts should be determined by compliance requirements specific to the end-application and applicable market regulations. The 4590-106K is appropriate for applications where RoHS compliance is not mandated. The 4590R-106K is the required selection for designs targeting markets or applications subject to RoHS3 regulatory requirements. Both components are electrically and mechanically interchangeable with no functional performance differences across the specified operating envelope of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Are the 4590-106K and 4590R-106K electrically interchangeable? A: Yes. Both components are electrically identical, sharing 10 mH inductance, 300 mA current rating, 7.3 ohm DC resistance, and ferrite core construction with identical ±10% tolerance specifications.

Q: What is the difference between these two part numbers? A: The 4590R-106K achieves ROHS3 compliance while the 4590-106K is RoHS non-compliant. All electrical and mechanical parameters are identical.
