S1008-103K Equivalent & Substitute Parts

Part Overview

The S1008-103K is a fixed surface mount inductor manufactured by API Delevan Inc. in the S1008 series. This shielded ferrite core inductor is rated for 10 µH inductance with a maximum DC resistance of 2.1 Ohm and supports a current rating of 230 mA. The component is housed in a 1008 (2520 Metric) package and operates across the temperature range of -55°C to 125°C. The S1008-103K is currently in active product status. Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable or when design requirements necessitate alternative compliance certifications or inventory considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the S1008-103K are determined by strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

Electrical Parameters: Inductance value (10 µH), inductance tolerance (±10%), current rating (230 mA), DC resistance maximum (2.1 Ohm), Q factor (30 @ 7.9 MHz), and self-resonant frequency (29 MHz) must be identical.

Mechanical Parameters: Package type (1008 / 2520 Metric), mounting type (Surface Mount), and physical dimensions (0.115" L x 0.105" W / 2.92mm x 2.66mm, height 0.095" / 2.41mm max) must match exactly.

Material & Construction: Core material (Ferrite) and shielding type (Shielded) must be identical.

Environmental Parameters: Operating temperature range (-55°C ~ 125°C) and moisture sensitivity level (MSL 1 / Unlimited) must be equivalent.

Parts meeting all these criteria are classified as direct substitutes and can be used interchangeably in circuit designs without modification to PCB layouts or electrical schematics.

Parameter Comparison

Engineering Selection Recommendations

The S1008R-103K is a direct electrical and mechanical equivalent to the S1008-103K. Both parts are manufactured by API Delevan Inc. and share identical electrical specifications, physical dimensions, and operating characteristics. Both components are in active product status.

The primary distinction between these parts is regulatory compliance. The S1008-103K is RoHS non-compliant, while the S1008R-103K is ROHS3 compliant. Selection between these parts should be based on the regulatory requirements of the end application and target market. Applications requiring RoHS3 compliance must use the S1008R-103K. Applications without RoHS compliance requirements may use either part based on availability and supply chain considerations.

Both parts maintain identical REACH and ECCN classifications, ensuring equivalent export and regulatory treatment in these categories.

Frequently Asked Questions (FAQ)

Q: Can the S1008R-103K be used as a direct replacement for the S1008-103K in existing designs?

A: Yes. The S1008R-103K is electrically and mechanically equivalent to the S1008-103K. All electrical parameters, physical dimensions, and operating characteristics are identical. No circuit modifications or PCB layout changes are required for substitution.

Q: What is the difference between the S1008-103K and S1008R-103K?

A: The primary difference is RoHS compliance status. The S1008-103K is RoHS non-compliant, while the S1008R-103K is ROHS3 compliant. All other specifications, including inductance, current rating, DC resistance, package type, and operating temperature range, are identical.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance, use the S1008R-103K. For applications without RoHS compliance mandates, either part may be used based on availability and supply chain factors.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the S1008-103K and S1008R-103K use the 1008 (2520 Metric) package with identical 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 are identical.

Q: Do these parts have the same moisture sensitivity level?

A: Yes. Both parts have a Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are the electrical performance characteristics identical?

A: Yes. Both parts have identical inductance (10 µH), tolerance (±10%), current rating (230 mA), DC resistance (2.1 Ohm max), Q factor (30 @ 7.9 MHz), and self-resonant frequency (29 MHz).
