Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S1008-561K is determined by electrical and mechanical parameter equivalence:

Critical Substitution Parameters:

• Inductance value and tolerance (560 nH ±10%)
• Current rating (790 mA minimum)
• DC resistance (180mOhm maximum)
• Shielding type (Shielded)
• Core material (Ferrite)
• Package classification (1008/2520 Metric)
• Physical dimensions (matching footprint)
• Frequency performance (Self Resonant Frequency, Q Factor)
• Operating temperature range (-55°C to 125°C)

The S1008R-561K qualifies as a direct substitute because it maintains identical electrical specifications (560 nH inductance, 790 mA current rating, 180mOhm DCR, 40 Q @ 25MHz, 232 MHz self resonant frequency) and mechanical compatibility (1008 package, surface mount, identical dimensions). Both components are manufactured by the same supplier and operate within the same temperature envelope.

Parameter Comparison

Engineering Selection Recommendations

The S1008R-561K is a direct electrical and mechanical equivalent to the S1008-561K with one significant distinction: RoHS compliance status. The original S1008-561K is RoHS non-compliant, while the S1008R-561K meets ROHS3 compliance requirements. For applications subject to RoHS directives or end-use markets requiring RoHS certification, the S1008R-561K is the appropriate selection. Both parts are Active products from the same manufacturer, ensuring continuity of supply and performance characteristics. The S1008R-561K also shows higher inventory availability (3008 units versus 1082 units), supporting procurement reliability.

Frequently Asked Questions (FAQ)

Q: Can the S1008R-561K replace the S1008-561K in existing designs? A: Yes. Both components are electrically and mechanically identical across all specified parameters including inductance, current rating, DC resistance, frequency characteristics, temperature range, and physical dimensions. No circuit modifications are required.

Q: What is the difference between these two parts? A: The primary difference is RoHS compliance certification. The S1008R-561K is ROHS3 compliant, while the S1008-561K is not RoHS compliant. All electrical and mechanical specifications remain identical.

Q: Will the S1008R-561K fit the same PCB footprint? A: Yes. Both components share identical package classification (1008/2520 Metric), mounting type (Surface Mount), and physical dimensions (0.115" L x 0.105" W, 2.41mm max height). Direct footprint compatibility is confirmed.

Q: Are there any performance differences between these inductors? A: No performance differences exist. Both components deliver identical inductance (560 nH ±10%), current handling (790 mA), DC resistance (180mOhm max), quality factor (40 @ 25MHz), self resonant frequency (232 MHz), and temperature performance (-55°C to 125°C).

Q: Which part should I select for new designs? A: For applications requiring RoHS compliance, select the S1008R-561K. For applications without RoHS requirements, either part is functionally suitable. Consider the S1008R-561K as the standard choice due to its RoHS3 compliance alignment with modern regulatory requirements.

Q: Is the MSL (Moisture Sensitivity Level) rating the same? A: Yes. Both components are rated at MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.
