Engineering Selection Recommendations

S1210-153K (Main Part): The S1210-153K is an active production part from API Delevan Inc. with RoHS non-compliant status. This part is suitable for applications where RoHS compliance is not a regulatory requirement. Current inventory availability is 979 pieces.

S1210R-153K (Substitute Part): The S1210R-153K is an active production part from API Delevan Inc. with ROHS3 compliance certification. This part is functionally and mechanically equivalent to the S1210-153K across all electrical and physical parameters. The S1210R-153K is the appropriate selection for applications requiring RoHS3 compliance. Current inventory availability is 1741 pieces. Both parts maintain identical REACH Unaffected status and ECCN/HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can the S1210R-153K be used as a direct replacement for the S1210-153K in all applications?

A: The S1210R-153K is electrically and mechanically equivalent to the S1210-153K. The primary difference is RoHS compliance status. If your application does not require RoHS3 compliance, both parts are functionally interchangeable. If RoHS3 compliance is required, the S1210R-153K must be used.

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

A: No. Both parts have identical inductance (15 µH), current rating (254 mA), DC resistance (2.5 Ohm max), Q factor (40 @ 2.5 MHz), self resonant frequency (23 MHz), and operating temperature range (-55°C to 125°C).

Q: Do these parts have the same physical footprint?

A: Yes. Both parts use the 1210 (3225 Metric) package with identical dimensions of 0.128" L x 0.095" W (3.25mm x 2.42mm) and seated height of 0.101" (2.57mm). They are pin-for-pin compatible on PCB layouts.

Q: What is the difference between the S1210 and S1210R series designations?

A: The series designation change from S1210 to S1210R reflects the RoHS3 compliance upgrade. All other specifications remain identical.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both the S1210-153K and S1210R-153K are supplied in Tape & Reel (TR) format suitable for automated assembly processes.

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

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.
