Substitute Part Grouping Explanation

The S1210R-393K serves as a direct substitute for the S1210-393K based on electrical and mechanical parameter equivalence. Substitution compatibility is determined by the following critical parameters that remain identical between the two parts:

• Inductance Value: 39 µH
• Tolerance: ±10%
• Current Rating: 179 mA
• DC Resistance (Max): 5Ω
• Shielding Type: Shielded
• Core Material: Ferrite
• Package Format: 1210 (3225 Metric)
• Operating Temperature Range: -55°C ~ 125°C
• Physical Dimensions: 0.128" L x 0.095" W (3.25mm x 2.42mm); Height 0.101" (2.57mm)
• Q @ Frequency: 40 @ 2.5MHz
• Frequency - Self Resonant: 12MHz

The S1210R-393K, belonging to the S1210R series, maintains identical electrical performance characteristics and mechanical compatibility, enabling direct substitution in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the S1210-393K and S1210R-393K maintain Active product status and are manufactured by API Delevan Inc. The primary differentiation lies in RoHS compliance status. The S1210-393K is RoHS non-compliant, while the S1210R-393K achieves ROHS3 compliance. Selection between these parts depends on regulatory requirements: choose the S1210R-393K for applications subject to RoHS3 directives, such as those in the European Union market or for manufacturers implementing RoHS3 standards. Both parts share identical electrical and mechanical specifications, moisture sensitivity levels (MSL 1), REACH status, and trade classification codes. The S1210R-393K provides higher availability with 5233 units in stock compared to 1069 units of the S1210-393K.

Frequently Asked Questions (FAQ)

Q: Can the S1210R-393K directly replace the S1210-393K in existing designs?

A: Yes. Both parts share identical inductance (39 µH), tolerance (±10%), current rating (179 mA), DC resistance (5Ω max), shielding, core material, package format (1210/3225 Metric), dimensions, temperature range (-55°C to 125°C), and frequency characteristics. Mechanical and electrical compatibility is complete.

Q: What is the primary difference between these two parts?

A: The S1210R-393K is ROHS3 compliant, while the S1210-393K is RoHS non-compliant. All electrical and mechanical parameters are identical.

Q: Are there any considerations for PCB layout or assembly when switching between these parts?

A: No. Both parts use surface mount technology in the same 1210 (3225 Metric) package with identical physical dimensions (0.128" L x 0.095" W, height 0.101" max). PCB footprints and assembly procedures remain unchanged.

Q: Which part should be used for new product designs?

A: The S1210R-393K is recommended for new designs due to ROHS3 compliance certification and higher inventory availability. The part maintains all functional specifications of the original S1210-393K.

Q: Do these inductors require any special handling during storage or assembly?

A: Both parts have Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no special moisture control or storage restrictions are required during component handling or assembly.
