S1008-331K Shielded Inductor Equivalent & Substitute Parts

Part Overview

The S1008-331K is a fixed shielded inductor manufactured by API Delevan Inc., designed for surface mount applications requiring 330 nH inductance with 865 mA current rating. This component is classified as Active product status and is currently in stock with 2392 units available. The S1008-331K operates across the temperature range of -55°C to 125°C and is suitable for RF and high-frequency circuit applications where shielding is required to minimize electromagnetic interference.

Substitute parts become necessary when the original component reaches end-of-life status, when supply chain constraints limit availability, or when design requirements mandate compliance with specific regulatory standards such as RoHS3 certification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S1008-331K is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Inductance value: 330 nH
• Inductance tolerance: ±10%
• Current rating: 865 mA minimum
• DC resistance: 150 mOhm maximum
• Shielding requirement: Shielded configuration
• Core material: Ferrite

Mechanical Parameters (Must Match Exactly):

• Package / Case: 1008 (2520 Metric)
• Mounting type: Surface Mount
• Packaging format: Tape & Reel (TR)

Performance Parameters (Must Match Exactly):

• Q factor @ 25 MHz: 40
• Self resonant frequency: 293 MHz
• Operating temperature range: -55°C to 125°C

The S1008R-331K qualifies as a direct substitute because it maintains identical electrical, mechanical, and performance specifications across all provided parameters while offering improved regulatory compliance status.

Engineering Selection Recommendations

S1008R-331K as Primary Selection:

The S1008R-331K is the qualified substitute for the S1008-331K based on complete electrical and mechanical equivalence. Both components are manufactured by API Delevan Inc. and maintain identical specifications across inductance, current rating, DC resistance, shielding configuration, core material, Q factor, self-resonant frequency, operating temperature range, package type, and mounting method.

The S1008R-331K provides an additional advantage through ROHS3 compliance certification, whereas the S1008-331K is classified as RoHS non-compliant. This distinction becomes relevant for applications subject to RoHS3 regulatory requirements or for organizations implementing RoHS3 compliance policies across their component supply chain.

Both parts maintain identical Moisture Sensitivity Level (MSL 1 - Unlimited), REACH Unaffected status, ECCN classification (EAR99), and HTSUS code (8504.50.8000), ensuring equivalent handling, storage, and regulatory documentation requirements.

Inventory availability is comparable for both parts, with 2392 units of S1008-331K and 2387 units of S1008R-331K currently in stock as new original components.

Frequently Asked Questions (FAQ)

Q: Can the S1008R-331K be used as a direct replacement for the S1008-331K in existing designs?

A: Yes. The S1008R-331K is electrically and mechanically equivalent to the S1008-331K across all specified parameters including inductance (330 nH), current rating (865 mA), DC resistance (150 mOhm max), shielding configuration, core material (ferrite), Q factor (40 @ 25 MHz), self-resonant frequency (293 MHz), operating temperature range (-55°C to 125°C), and package type (1008 / 2520 Metric surface mount). No circuit modifications or PCB layout changes are required.

Q: What is the difference between the S1008-331K and S1008R-331K?

A: The primary difference is regulatory compliance status. The S1008R-331K is ROHS3 compliant, while the S1008-331K is RoHS non-compliant. All other electrical, mechanical, and performance specifications are identical. Both components are manufactured by API Delevan Inc. and share the same series designation prefix (S1008).

Q: Are there any compatibility concerns with the 1008 (2520 Metric) package format?

A: No. Both the S1008-331K and S1008R-331K use the identical 1008 (2520 Metric) surface mount package with dimensions of 0.115" L x 0.105" W (2.92mm x 2.66mm) and maximum seated height of 0.095" (2.41mm). PCB footprints, solder pad layouts, and pick-and-place machine settings remain unchanged between these parts.

Q: What is the Moisture Sensitivity Level (MSL) for these inductors?

A: Both the S1008-331K and S1008R-331K are classified as MSL 1 (Unlimited), indicating unlimited shelf life without moisture bake-out requirements. Standard dry storage conditions are sufficient for both components.

Q: Are these parts suitable for high-frequency RF applications?

A: Yes. Both inductors are designed for high-frequency operation with a self-resonant frequency of 293 MHz and Q factor of 40 at 25 MHz. The shielded ferrite core configuration minimizes electromagnetic interference in RF and high-frequency circuit applications.

Q: What is the current handling capability of these inductors?

A: Both the S1008-331K and S1008R-331K are rated for 865 mA continuous current with a maximum DC resistance of 150 mOhm. These specifications determine the thermal performance and power dissipation characteristics in the application circuit.

Q: Do these inductors require any special handling or storage procedures?

A: Both components have MSL 1 rating (Unlimited), requiring no special moisture control procedures. Standard component storage at room temperature and normal humidity conditions is appropriate. Both parts are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
