API Delevan 4590-825K Equivalent & Substitute Parts

Part Overview

The API Delevan 4590-825K is a fixed inductance through-hole component classified as an 8.2 mH unshielded drum core wirewound inductor. This component is designed for applications requiring moderate inductance values with axial lead configuration and ferrite core construction. The part is currently in active production status with 894 pieces available in new original inventory.

Substitute parts become necessary when original inventory is depleted, when design revisions require RoHS compliance, or when alternative sourcing is required to maintain supply chain continuity. The 4590-825K is RoHS non-compliant, which may necessitate substitution in applications subject to RoHS regulations.

Substitute Part Grouping Explanation

Substitution eligibility for the 4590-825K is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match exactly to establish a valid substitute relationship:

Electrical Parameters (Must Match):

• Inductance value: 8.2 mH
• Inductance tolerance: ±10%
• Current rating: 320 mA
• Saturation current: 200 mA
• DC resistance: 6.44 Ohm maximum
• Core material: Ferrite
• Shielding configuration: Unshielded

Mechanical Parameters (Must Match):

• Mounting type: Through Hole
• Package configuration: Axial
• Physical dimensions: 0.455" Dia × 0.900" L (11.55mm × 22.86mm)
• Operating temperature range: −55°C to +125°C

Environmental & Compliance Parameters:

• Test frequency: 1 kHz
• ECCN classification: EAR99
• HTSUS code: 8504.50.4000

The substitute part 4590R-825K meets all electrical and mechanical equivalence criteria. The primary distinction between the main part and its substitute is the RoHS compliance status, which does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

4590R-825K as Primary Substitute:

The 4590R-825K is a direct electrical and mechanical equivalent to the 4590-825K. Both components are manufactured by API Delevan Inc. and share identical specifications across all critical parameters: inductance, current rating, saturation current, DC resistance, core material, shielding configuration, mounting type, package geometry, and operating temperature range.

The 4590R-825K differs from the main part only in RoHS compliance status. The 4590R-825K is ROHS3 compliant, whereas the 4590-825K is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulations or for designs requiring compliance with environmental directives.

Selection Criteria:

• For RoHS-regulated applications: Select 4590R-825K
• For non-regulated applications with inventory constraints: Either part is electrically and mechanically interchangeable
• For supply chain continuity: The 4590R-825K has higher inventory availability (1677 pieces versus 894 pieces)

Both parts maintain identical electrical performance, physical footprint, and thermal characteristics, ensuring direct substitution without circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can the 4590R-825K be used as a direct replacement for the 4590-825K in existing designs?

A: Yes. The 4590R-825K is electrically and mechanically identical to the 4590-825K. All critical parameters—inductance, current rating, DC resistance, core material, shielding, mounting type, package configuration, and physical dimensions—are equivalent. Direct substitution requires no circuit modifications or PCB layout changes.

Q: What is the difference between the 4590-825K and 4590R-825K?

A: The primary difference is RoHS compliance status. The 4590R-825K is ROHS3 compliant, while the 4590-825K is RoHS non-compliant. All electrical and mechanical specifications are identical.

Q: Are there any compatibility issues when substituting the 4590R-825K for the 4590-825K?

A: No compatibility issues exist. Both components have identical axial through-hole package configuration, physical dimensions (0.455" Dia × 0.900" L), and electrical characteristics. They are pin-compatible and functionally equivalent.

Q: Which part should be selected for new designs?

A: For new designs subject to RoHS regulations or environmental compliance requirements, the 4590R-825K is the appropriate selection. For applications without regulatory constraints, either part is suitable based on availability and supply chain considerations.

Q: Do the 4590-825K and 4590R-825K have the same operating temperature range?

A: Yes. Both components operate across the identical temperature range of −55°C to +125°C.

Q: Is the DC resistance specification identical between both parts?

A: Yes. Both the 4590-825K and 4590R-825K have a maximum DC resistance of 6.44 Ohm.

Q: Can these inductors be used interchangeably in high-frequency applications?

A: Both components are tested at 1 kHz. Applications requiring operation at frequencies significantly different from the test frequency should be evaluated based on the specific circuit requirements and frequency-dependent characteristics of ferrite drum core inductors.
