Key Parameters

Substitute Part Grouping Explanation

Substitution of the S1008-822K is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Inductance value: 8.2 µH with ±10% tolerance
• Current rating: 240 mA minimum
• DC resistance: 1.9 Ohm maximum
• Q factor: 30 @ 7.9 MHz
• Self resonant frequency: 32 MHz

Mechanical Parameters:

• Package type: 1008 (2520 Metric)
• Mounting type: Surface Mount
• Shielding: Shielded configuration
• Core material: Ferrite

Environmental Parameters:

• Operating temperature range: -55°C ~ 125°C
• Moisture sensitivity level: 1 (Unlimited)

The substitute part S1008R-822K maintains identical electrical and mechanical specifications to the main part, with the primary distinction being compliance certification status.

Engineering Selection Recommendations

S1008-822K Selection Criteria: The S1008-822K is suitable for applications where RoHS compliance is not a design requirement. This part maintains active production status and is available in inventory quantities of 957 pieces.

S1008R-822K Selection Criteria: The S1008R-822K is the preferred substitute when ROHS3 compliance is mandated by design specifications or regulatory requirements. This variant is ROHS3 compliant and maintains identical electrical and mechanical performance to the S1008-822K. Inventory availability is higher at 2349 pieces. Both parts are REACH Unaffected and carry the same ECCN and HTSUS classifications.

The selection between these two parts is determined solely by compliance requirements, as all functional and mechanical parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can S1008R-822K be used as a direct replacement for S1008-822K in all applications?

A: Yes, the S1008R-822K is electrically and mechanically equivalent to the S1008-822K. The primary difference is ROHS3 compliance status. If your application or end-market does not require RoHS compliance, either part is functionally interchangeable. If RoHS compliance is required, use S1008R-822K.

Q: Are the physical dimensions identical between S1008-822K and S1008R-822K?

A: Yes. Both parts share identical dimensions of 0.115" L x 0.105" W (2.92mm x 2.66mm) with a maximum seated height of 0.095" (2.41mm). Both are packaged in the 1008 (2520 Metric) case and are surface mount compatible.

Q: What is the inductance tolerance for these parts?

A: Both the S1008-822K and S1008R-822K have an inductance tolerance of ±10% at the specified test frequency of 7.9 MHz.

Q: Are there any differences in electrical performance between these two parts?

A: No. Both parts have identical electrical specifications: 8.2 µH inductance, 240 mA current rating, 1.9 Ohm maximum DC resistance, Q factor of 30 @ 7.9 MHz, and self resonant frequency of 32 MHz.

Q: What is the moisture sensitivity level for these inductors?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited moisture sensitivity protection.

Q: Can these parts be used in the full temperature range of -55°C to 125°C?

A: Yes. Both S1008-822K and S1008R-822K are rated for continuous operation across the -55°C to 125°C temperature range.
