Substitute Part Grouping Explanation

Substitute parts for the S1210-561K are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are:

Critical Parameters for Substitution:

• Inductance value: 560 nH with ±10% tolerance
• Current rating: 619 mA minimum
• DC resistance: 500 mOhm maximum
• Package format: 1210 (3225 Metric) surface mount
• Shielding type: Shielded configuration
• Core material: Iron
• Operating temperature range: -55°C to 125°C minimum

The S1210R-561K qualifies as a direct substitute because it maintains identical electrical specifications and mechanical compatibility with the main part number across all critical parameters.

Engineering Selection Recommendations

S1210-561K (Original Part):

• Product Status: Active
• RoHS Status: RoHS non-compliant
• REACH Status: REACH Unaffected
• Current inventory: 923 Pcs New Original In Stock

S1210R-561K (Substitute Part):

• Product Status: Active
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected
• Current inventory: 1310 Pcs New Original In Stock

The S1210R-561K provides equivalent electrical and mechanical performance with the additional advantage of ROHS3 compliance. Both parts maintain identical functional specifications and are suitable for direct substitution in applications requiring 560 nH shielded inductors in the 1210 surface mount package. Selection between these parts should be based on regulatory compliance requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the S1210R-561K replace the S1210-561K in existing designs?

A: Yes. The S1210R-561K is electrically and mechanically equivalent to the S1210-561K. All critical parameters including inductance, current rating, DC resistance, package dimensions, and operating temperature range are identical. Direct substitution is supported without circuit redesign.

Q: What is the difference between S1210-561K and S1210R-561K?

A: The primary difference is RoHS compliance status. The S1210R-561K is ROHS3 compliant, while the S1210-561K is RoHS non-compliant. All electrical specifications and mechanical characteristics remain identical between the two part numbers.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 1210 (3225 Metric) surface mount package with identical dimensions of 0.128" L x 0.095" W (3.25mm x 2.42mm) and maximum seated height of 0.101" (2.57mm). PCB footprints are interchangeable.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by matching inductance value (560 nH ±10%), current rating (619 mA), DC resistance (500 mOhm maximum), package format (1210 surface mount), shielding configuration (shielded), core material (iron), and operating temperature range (-55°C to 125°C).

Q: Can these inductors be used in high-frequency applications?

A: Both parts are rated for operation up to 200 MHz self-resonant frequency with a Q factor of 40 at 25 MHz, supporting high-frequency circuit applications within these specifications.
