Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the S1008-101K are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

Electrical Parameters (Must Match):

• Inductance value: 100 nH
• Inductance tolerance: ±10%
• Current rating: 1.12 A minimum
• DC resistance: 90 mOhm maximum
• Shielding type: Shielded
• Core material: Ferrite
• Q factor @ 25 MHz: 40
• Self resonant frequency: 383 MHz
• Operating temperature range: -55°C to 125°C

Mechanical Parameters (Must Match):

• Package / Case: 1008 (2520 Metric)
• Mounting type: Surface Mount
• Physical dimensions: 0.115" L × 0.105" W (2.92mm × 2.66mm)
• Height (seated max): 0.095" (2.41mm)

Compliance & Certification Parameters:

• Moisture sensitivity level: 1 (Unlimited)
• REACH status: REACH Unaffected
• ECCN classification: EAR99

Substitute parts must satisfy all electrical and mechanical parameters without deviation. Compliance status differences are noted separately and do not disqualify substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

The S1008R-101K is a direct electrical and mechanical equivalent to the S1008-101K. All critical electrical parameters—inductance, current rating, DC resistance, Q factor, and self resonant frequency—are identical. Physical dimensions, package type, and mounting specifications are identical, ensuring drop-in compatibility in PCB layouts and assembly processes.

The primary distinction between these parts is RoHS compliance status. The S1008-101K is RoHS non-compliant, while the S1008R-101K is ROHS3 compliant. Selection between these parts depends on regulatory requirements applicable to the end application and target markets.

Both parts maintain identical operating temperature ranges (-55°C to 125°C), moisture sensitivity levels (MSL 1), and REACH/ECCN classifications, confirming compatibility across environmental and regulatory frameworks.

Frequently Asked Questions (FAQ)

Q: Can S1008R-101K be used as a direct replacement for S1008-101K in existing designs?

A: Yes. All electrical parameters (inductance, current rating, DC resistance, Q factor, self resonant frequency) and mechanical parameters (package, dimensions, mounting type) are identical. The parts are electrically and mechanically interchangeable.

Q: What is the difference between S1008-101K and S1008R-101K?

A: The primary difference is RoHS compliance status. S1008-101K is RoHS non-compliant; S1008R-101K is ROHS3 compliant. All other specifications are identical.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance status reflects manufacturing process and material composition standards but does not alter the electrical characteristics or performance of the inductor.

Q: Are both parts available in the same packaging format?

A: Yes. Both S1008-101K and S1008R-101K are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: What is the physical footprint compatibility between these parts?

A: Both parts use the 1008 (2520 Metric) package with identical dimensions: 0.115" L × 0.105" W (2.92mm × 2.66mm) and maximum seated height of 0.095" (2.41mm). PCB layouts and assembly fixtures require no modification.

Q: Which part should be selected for RoHS-regulated applications?

A: S1008R-101K is ROHS3 compliant and is the appropriate selection for applications subject to RoHS directives or customer requirements mandating RoHS compliance.

Q: Are there any temperature or environmental performance differences?

A: No. Both parts operate across the identical temperature range (-55°C to 125°C) and share identical moisture sensitivity levels (MSL 1, Unlimited). Environmental performance is equivalent.
