Engineering Selection Recommendations

1008-471K (Tape & Reel Packaging)

The 1008-471K is supplied in Tape & Reel (TR) format and carries RoHS non-compliant status. This part is suitable for applications where RoHS compliance is not a regulatory requirement and where Tape & Reel packaging format is preferred for automated assembly processes.

1008R-471K (Cut Tape & Digi-Reel® Packaging)

The 1008R-471K is supplied in Cut Tape (CT) and Digi-Reel® format and is ROHS3 compliant. This part is suitable for applications requiring RoHS3 compliance and where Cut Tape or Digi-Reel® packaging formats are compatible with assembly equipment. The 1008R-471K offers significantly higher inventory availability (631,400 Pcs) compared to the 1008-471K (1,044 Pcs).

Selection Criteria:

For RoHS3 Compliant Applications: Select 1008R-471K
For Non-RoHS Applications with TR Packaging Requirement: Select 1008-471K
For Inventory Availability: 1008R-471K provides superior stock levels
For Packaging Format Compatibility: Verify assembly equipment compatibility with Cut Tape & Digi-Reel® or Tape & Reel formats

Both parts are Active status products from API Delevan Inc. and are electrically and mechanically identical. Selection between these parts is determined by regulatory compliance requirements and packaging format compatibility with manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Are the 1008-471K and 1008R-471K electrically interchangeable?

A: Yes. Both parts have identical inductance (470 nH), current rating (846 mA), DC resistance (210 mOhm Max), Q factor (40 @ 25 MHz), self resonant frequency (215 MHz), core material (Ferrite), shielding (Unshielded), and operating temperature range (-55°C to 125°C). They are electrically equivalent for circuit applications.

Q: Are the 1008-471K and 1008R-471K mechanically interchangeable?

A: Yes. Both parts have identical physical dimensions (0.105" L x 0.095" W / 2.66 mm x 2.41 mm), seated height (0.095" / 2.41 mm), mounting type (Surface Mount), and moisture sensitivity level (1 - Unlimited). They are mechanically equivalent for PCB placement and assembly.

Q: What is the difference between Tape & Reel (TR) and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on a reel, suitable for high-speed automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel® packaging supplies components on tape segments or alternative reel formats, suitable for lower-volume assembly or equipment with different tape handling capabilities. The component specifications remain identical; only the packaging format differs.

Q: Why does the 1008R-471K have ROHS3 compliance while the 1008-471K does not?

A: RoHS compliance status reflects the manufacturing process and material composition used by the supplier. The 1008R-471K series was manufactured to meet ROHS3 (Restriction of Hazardous Substances Directive 3) requirements, while the 1008-471K was not. Both parts are functionally identical; compliance status is a manufacturing and regulatory attribute.

Q: Can I use 1008R-471K in place of 1008-471K in my design?

A: Yes, provided your application does not have specific packaging format requirements that conflict with Cut Tape & Digi-Reel® format. If your assembly equipment is compatible with this packaging format and RoHS3 compliance is acceptable or required, the 1008R-471K is a direct substitute. Verify packaging compatibility with your manufacturing process before implementation.

Q: Can I use 1008-471K in place of 1008R-471K in my design?

A: Yes, provided your application does not require RoHS3 compliance and your assembly equipment is compatible with Tape & Reel (TR) packaging format. If RoHS3 compliance is a regulatory requirement for your application, the 1008-471K is not suitable. Verify packaging compatibility with your manufacturing process before implementation.

Q: What is the inductance tolerance for these parts?

A: Both the 1008-471K and 1008R-471K have an inductance tolerance of ±10%. This means the actual inductance value will be within the range of 423 nH to 517 nH (470 nH ±10%).

Q: What is the maximum DC resistance for these inductors?

A: Both parts have a maximum DC resistance (DCR) of 210 mOhm. This specification ensures predictable power dissipation and thermal performance in circuit applications.

Q: What is the current rating for these inductors?

A: Both parts are rated for 846 mA continuous current. This is the maximum sustained current the inductor can carry without exceeding design specifications.

Q: Are these inductors suitable for high-frequency applications?

A: Yes. Both parts have a self-resonant frequency of 215 MHz and a Q factor of 40 at 25 MHz, making them suitable for RF and high-frequency circuit applications within their specified frequency range.
