Substitute Part Grouping Explanation

The S1210R-182K is identified as a direct substitute for the S1210-182K based on the following critical parameters that determine functional equivalence:

• Inductance Value: Both parts specify 1.8 µH with ±10% tolerance
• Current Rating: Both rated for 498 mA continuous current
• DC Resistance: Both maintain 650mOhm maximum DC resistance
• Package / Case: Both use 1210 (3225 Metric) surface mount package
• Physical Dimensions: Identical footprint (0.128" L x 0.095" W / 3.25mm x 2.42mm) and height (0.101" / 2.57mm maximum seated height)
• Core Material: Both utilize ferrite core construction
• Shielding: Both are shielded designs
• Operating Temperature: Both operate across -55°C to 125°C range
• Electrical Performance: Both exhibit Q of 40 @ 7.9MHz and self-resonant frequency of 95MHz

The substitution is valid for applications where the specified electrical characteristics and mechanical form factor are required.

Parameter Comparison

Engineering Selection Recommendations

Both the S1210-182K and S1210R-182K are active production components from API Delevan Inc. with identical electrical and mechanical specifications. The primary distinction is regulatory compliance status: the S1210R-182K is ROHS3 compliant, while the S1210-182K is RoHS non-compliant. Selection between these parts should be based on the regulatory requirements of the end application and target market. The S1210R-182K offers superior compliance posture for applications subject to RoHS directives. Both parts maintain equivalent REACH and ECCN classifications. Inventory availability differs significantly, with the S1210R-182K offering substantially higher stock levels (58508 pcs vs. 720 pcs).

Frequently Asked Questions (FAQ)

Q: Are the S1210-182K and S1210R-182K electrically interchangeable?

A: Yes. Both parts specify identical inductance (1.8 µH ±10%), current rating (498 mA), DC resistance (650mOhm maximum), Q factor (40 @ 7.9MHz), and self-resonant frequency (95MHz). They are electrically equivalent for circuit applications.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Both parts use the identical 1210 (3225 Metric) surface mount package with matching footprint dimensions (0.128" L x 0.095" W) and maximum seated height (0.101"). No PCB layout modifications are required for substitution.

Q: What is the difference between S1210-182K and S1210R-182K?

A: The primary difference is RoHS compliance status. The S1210R-182K is ROHS3 compliant, while the S1210-182K is RoHS non-compliant. All other electrical, mechanical, and thermal specifications are identical.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS compliance, the S1210R-182K is the appropriate choice. Both parts are active in production and suitable for new designs.

Q: Are there any thermal or frequency performance differences?

A: No. Both parts operate across the identical temperature range (-55°C to 125°C) and exhibit identical frequency characteristics (Q of 40 @ 7.9MHz, self-resonant frequency of 95MHz).

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

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
