1812-223J Fixed Inductor 22µH 250mA

Part Overview

The 1812-223J is a fixed unshielded ferrite core inductor manufactured by API Delevan Inc., rated for 22 µH inductance with a maximum current handling capacity of 250 mA. The component features a maximum DC resistance of 3.2 Ohm and operates across the temperature range of -55°C to 125°C. This surface mount inductor in 1812 (4532 Metric) package form factor is currently in active production status with 1,141 pieces available in stock.

Alternative part selection becomes necessary when supply constraints occur, RoHS3 compliance is required for new designs, or when operating temperature requirements differ from the standard specification. Two substitute components provide equivalent electrical performance within defined parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the 1812-223J is determined by strict adherence to the following critical electrical and mechanical parameters:

Electrical Equivalence Requirements:

• Inductance value: 22 µH (within ±5% tolerance)
• Current rating: minimum 250 mA
• DC resistance: maximum 3.2 Ohm
• Operating temperature range: must accommodate -55°C to 125°C
• Self resonant frequency: 13 MHz
• Q factor at test frequency: 50 @ 2.5 MHz or equivalent

Mechanical Compatibility Requirements:

• Package / Case: 1812 (4532 Metric)
• Mounting type: Surface Mount
• Physical dimensions: 0.177" L x 0.126" W (4.50mm x 3.20mm)
• Maximum seated height: 0.134" (3.40mm)
• Shielding type: Unshielded

Substitute parts must match all listed electrical specifications and maintain identical mechanical form factor to ensure direct PCB replacement without redesign or layout modification.

Engineering Selection Recommendations

1812R-223J (API Delevan Inc.)

The 1812R-223J from API Delevan Inc. provides direct electrical and mechanical compatibility with the 1812-223J. Both components are manufactured by the same supplier and share identical core specifications across all critical parameters. The primary distinction is RoHS3 compliance status of the 1812R-223J variant, making it the preferred selection for new designs where RoHS3 compliance is mandated. Both components are in active production with substantial inventory availability (1,141 units for 1812-223J and 5,203 units for 1812R-223J).

CM453232-220JL (Bourns Inc.)

The CM453232-220JL from Bourns Inc. matches the mechanical form factor and most electrical characteristics of the 1812-223J. However, this component carries a maximum current rating of 180 mA, which is lower than the 250 mA rating of the primary part. Selection of this substitute is limited to applications where the design current requirement does not exceed 180 mA. The CM453232-220JL is RoHS3 compliant and features a narrower operating temperature range of -40°C to 125°C. Inventory availability is high at 5,003 units.

Frequently Asked Questions (FAQ)

Q: Can the 1812R-223J be used as a direct replacement for the 1812-223J in all applications?

A: Yes. The 1812R-223J is electrically and mechanically equivalent to the 1812-223J across all specified parameters. The primary difference is the RoHS3 compliance status of the 1812R-223J. Selection should be based on regulatory compliance requirements for your application.

Q: Is the CM453232-220JL suitable for replacement in high-current applications?

A: The CM453232-220JL is rated for a maximum current of 180 mA, compared to 250 mA for the 1812-223J. This component is suitable only for applications where the design current remains at or below 180 mA. For applications requiring 250 mA current handling, the CM453232-220JL does not meet the electrical requirements.

Q: What is the impact of the operating temperature range difference in the CM453232-220JL?

A: The CM453232-220JL operates between -40°C and 125°C, whereas the 1812-223J operates between -55°C and 125°C. The CM453232-220JL does not meet specifications for applications requiring operation below -40°C. Designs operating exclusively above -40°C are not affected by this parameter difference.

Q: Are all three components housed in identical packages?

A: Yes. All three components utilize the 1812 (4532 Metric) surface mount package with identical external dimensions (0.177" L x 0.126" W, 4.50mm x 3.20mm) and maximum seated height (0.134", 3.40mm). Direct PCB replacement is mechanically supported without layout modification.

Q: What role does inductance tolerance play in substitution?

A: All three components maintain ±5% inductance tolerance around the 22 µH nominal value. This tolerance is consistent across all alternatives, ensuring predictable circuit behavior within the specified tolerance band.
