P1812-223K Equivalent & Substitute Parts

Part Overview

The P1812-223K is a fixed unshielded inductor manufactured by API Delevan Inc., rated for 22 µH inductance with a maximum current rating of 370 mA and DC resistance of 1.2 Ohm. The component is currently active in production and widely available in inventory. Alternative part models become necessary when specific compliance requirements, such as RoHS3 compliance, are mandated by design specifications or when supply chain considerations necessitate equivalent alternatives that maintain identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

The P1812R-223K qualifies as a direct functional equivalent to the P1812-223K based on identical electrical and mechanical parameters. Both components share the same inductance value (22 µH), tolerance (±10%), current rating (370 mA), saturation current (515 mA), DC resistance (1.2 Ohm maximum), operating temperature range (-55°C to 125°C), core material (Ferrite), shielding configuration (Unshielded), and package specifications (1812/4532 Metric). The key differentiator between these two parts is their compliance status: the P1812-223K is RoHS non-compliant, while the P1812R-223K is RoHS3 compliant. This distinction determines which part should be selected based on applicable regulatory and supply chain requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the P1812-223K and P1812R-223K are actively produced components suitable for 22 µH fixed inductor applications requiring 370 mA current capacity in 1812 package configurations. Selection between these parts depends on compliance requirements: the P1812-223K is appropriate for applications without RoHS3 restrictions, while the P1812R-223K must be selected for designs subject to RoHS3 directives or when organizational procurement standards mandate RoHS3 compliance. Both components carry identical REACH compliance status (REACH Unaffected) and moisture sensitivity rating (MSL 1), eliminating differential considerations in these areas. The P1812R-223K variant offers superior inventory availability (4,690 units versus 909 units), a relevant factor in supply chain planning.

Frequently Asked Questions (FAQ)

Q: What makes P1812R-223K a valid substitute for P1812-223K? A: Both components share identical electrical specifications (22 µH inductance, 370 mA current rating, 1.2 Ohm DCR), identical mechanical specifications (1812/4532 Metric package, 0.177" L x 0.126" W x 0.134" H), identical operating temperature range (-55°C to 125°C), and identical core material (Ferrite, Unshielded). The primary distinction is RoHS3 compliance status.

Q: Can P1812-223K be replaced with P1812R-223K in existing designs? A: Direct mechanical and electrical substitution is valid provided the design does not restrict component selection to non-compliant RoHS materials. Both parts occupy the same footprint, mount identically via Surface Mount configuration, and deliver equivalent inductance and current handling characteristics.

Q: Are there any package or footprint differences between these parts? A: No. Both components use the 1812 (4532 Metric) package with identical dimensions: 0.177" length, 0.126" width, and 0.134" maximum seated height. PCB layouts designed for either part are directly interchangeable.

Q: Which part should be selected for new designs? A: For applications governed by RoHS3 regulations or organizational RoHS3 procurement mandates, the P1812R-223K is the required selection. For applications without such restrictions, either part is functionally equivalent. The P1812R-223K offers superior inventory availability as an additional consideration.

Q: Do these inductors have different temperature performance characteristics? A: Both components operate across the identical temperature range of -55°C to 125°C. No differential thermal performance characteristics are specified in the provided technical data.
