4590-683K Equivalent & Substitute Parts

Part Overview

The 4590-683K is a 68 µH unshielded drum core wirewound inductor manufactured by API Delevan Inc., rated for 3.355 A continuous current with a maximum DC resistance of 59 mOhm. This through-hole axial component operates across the industrial temperature range of -55°C to 125°C and is currently in active production status.

Finding equivalent and substitute parts is necessary when the primary part number becomes unavailable, when supply chain constraints require alternative sourcing, or when design revisions call for components with improved compliance certifications while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the 4590-683K is determined by strict equivalence across the following critical parameters:

• Inductance value: 68 µH with ±10% tolerance
• Current rating: 3.355 A minimum
• Saturation current: 2.1 A minimum
• DC resistance: 59 mOhm maximum
• Core material: Ferrite drum core
• Shielding configuration: Unshielded
• Mounting and package: Through-hole axial
• Physical dimensions: 0.455" Dia x 0.900" L
• Operating temperature range: -55°C to 125°C
• Inductance test frequency: 1 kHz

The 4590R-683K qualifies as a direct substitute because it maintains identical electrical performance and mechanical specifications across all parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

Both the 4590-683K and 4590R-683K are active production components from API Delevan Inc. with identical electrical and mechanical specifications. The primary distinction is regulatory compliance status: the 4590R-683K carries ROHS3 certification, while the 4590-683K is RoHS non-compliant. Both components maintain REACH Unaffected status and share the same ECCN and HTSUS classifications.

Selection between these parts should be based on regulatory requirements applicable to the end application. Applications subject to RoHS3 directives require the 4590R-683K. Applications without RoHS3 requirements may use either part interchangeably from an electrical and mechanical standpoint.

Frequently Asked Questions (FAQ)

Q: Can the 4590R-683K replace the 4590-683K in existing designs?

A: Yes. The 4590R-683K is electrically and mechanically identical to the 4590-683K. Both components deliver 68 µH inductance at ±10% tolerance, support 3.355 A continuous current, and occupy the same 0.455" Dia x 0.900" L axial through-hole footprint. Direct substitution is valid from a circuit performance perspective.

Q: What is the difference between the 4590 and 4590R series?

A: The 4590R series variant incorporates ROHS3 compliance, whereas the 4590 series does not. All other electrical parameters, mechanical dimensions, and performance characteristics remain identical between the two series.

Q: Are there any PCB layout or mounting considerations when switching between these parts?

A: No. Both parts use identical through-hole axial packaging with the same lead spacing and physical dimensions. No PCB layout modifications are required when substituting between the 4590-683K and 4590R-683K.

Q: What inventory status should I consider when selecting between these parts?

A: The 4590R-683K maintains significantly higher inventory availability (25,400 pcs) compared to the 4590-683K (1,172 pcs). Supply chain considerations may favor the 4590R-683K for new designs or high-volume production.

Q: Do these parts have different temperature operating ranges?

A: No. Both the 4590-683K and 4590R-683K operate across the identical temperature range of -55°C to 125°C.
