1008-680K

Part Overview

The 1008-680K is a fixed unshielded inductor manufactured by API Delevan Inc. in the 1008 series with a nominal inductance of 68 nH and rated current of 823 mA. The component features a phenolic core and operates across the temperature range of -55°C to 125°C. This part is currently active in production. Identifying equivalent substitute parts becomes necessary when the primary part experiences supply constraints, inventory limitations, or when design specifications require alternative material compositions or compliance certifications while maintaining identical electrical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1008-680K are identified based on strict adherence to the following critical parameters:

• Inductance Value: 68 nH with ±10% tolerance
• Current Rating: 823 mA minimum
• DC Resistance (DCR): 180 mOhm maximum
• Operating Temperature Range: -55°C to 125°C
• Mounting Type: Surface Mount
• Physical Dimensions: 0.105" L x 0.095" W (2.66 mm x 2.41 mm) with height of 0.095" (2.41 mm) maximum
• Shielding Configuration: Unshielded
• Q Factor: 25 @ 50 MHz
• Self-Resonant Frequency: 1 GHz

The 1008R-680K qualifies as a direct substitute because it maintains all critical electrical specifications (inductance, current rating, DCR, temperature range, frequency characteristics) and physical dimensions while utilizing a ferrite core instead of phenolic. The core material change does not affect the electrical performance within the specified parameters and represents the only material-level difference between the parts.

Parameter Comparison

Engineering Selection Recommendations

Both the 1008-680K and 1008R-680K are active production parts from API Delevan Inc. and maintain electrical and mechanical compatibility across all critical parameters. The primary distinction between these parts is the material composition of the core and RoHS compliance status.

The 1008-680K utilizes a phenolic core and carries RoHS non-compliant status. The 1008R-680K utilizes a ferrite core and is ROHS3 compliant. Selection between these parts should be determined by specific design requirements regarding RoHS compliance and regulatory obligations. For applications with ROHS3 compliance requirements, the 1008R-680K is the appropriate selection. For applications without such constraints, either part fulfills the electrical and mechanical specifications identically.

Frequently Asked Questions (FAQ)

Q: Are the 1008-680K and 1008R-680K electrically interchangeable?

A: Yes. Both parts deliver identical inductance (68 nH), current rating (823 mA), DC resistance (180 mOhm maximum), quality factor (25 @ 50 MHz), and self-resonant frequency (1 GHz) across the operating temperature range of -55°C to 125°C.

Q: What is the difference between phenolic and ferrite core materials in these inductors?

A: The core material differs between the two parts. The 1008-680K uses phenolic core construction while the 1008R-680K uses ferrite core construction. Both materials deliver the specified electrical performance within the defined parameters.

Q: Can I use 1008R-680K as a drop-in replacement for 1008-680K?

A: Yes. The parts share identical physical dimensions (0.105" L x 0.095" W, height 0.095" maximum), identical mounting type (Surface Mount), identical package configuration (Nonstandard, Tape & Reel), and identical electrical specifications. No PCB layout modifications are required.

Q: Is there a compliance difference between these parts?

A: Yes. The 1008R-680K is ROHS3 compliant while the 1008-680K is RoHS non-compliant. Applications subject to ROHS3 requirements should specify the 1008R-680K.

Q: What inductance tolerance applies to both parts?

A: Both the 1008-680K and 1008R-680K carry a tolerance specification of ±10% on the 68 nH nominal inductance.
