API Delevan P1812-563K Fixed Inductor Equivalent & Substitute Parts

Part Overview

The API Delevan P1812-563K is an unshielded fixed inductor rated at 56 µH with 240 mA current capability and 2.268Ω maximum DC resistance. It is a surface mount component packaged in the 1812 (4532 Metric) form factor. The part maintains Active product status with 871 pieces in current inventory. Finding substitute parts becomes necessary when primary inventory is depleted or when RoHS compliance requirements change for system-level applications.

Key Parameters

Substitute Part Grouping Explanation

The P1812R-563K qualifies as a direct electrical and mechanical substitute for the P1812-563K based on the following critical parameters:

• Inductance Value: Both parts specify 56 µH with ±10% tolerance
• Current Rating: Both rated at 240 mA continuous current
• Saturation Current: Both specify 336 mA Isat
• DC Resistance: Both maintain 2.268Ω maximum DCR
• Package Configuration: Both use 1812 (4532 Metric) surface mount package
• Physical Dimensions: Both measure 0.177" L × 0.126" W (4.50mm × 3.20mm), with 0.134" (3.40mm) maximum seated height
• Core Material: Both use ferrite core construction
• Operating Temperature: Both support -55°C to 125°C operating range

The primary distinction between these parts is compliance status, addressed in the Engineering Selection Recommendations section.

Parameter Comparison

Engineering Selection Recommendations

P1812-563K: Use this part number when RoHS non-compliance is acceptable or when legacy system requirements specify this variant. This part is Active status with 871 units in inventory.

P1812R-563K: Use this part number for applications requiring ROHS3 compliance. This variant is electrically and mechanically identical to the P1812-563K while meeting enhanced environmental compliance requirements. This part is Active status with 2800 units in inventory, providing higher availability.

Both parts maintain identical electrical performance and physical dimensions. The selection between them depends exclusively on regulatory and compliance requirements for the target application.

Frequently Asked Questions (FAQ)

Q: Are P1812-563K and P1812R-563K electrically interchangeable?

A: Yes. Both parts specify identical inductance (56 µH), current rating (240 mA), saturation current (336 mA), and DC resistance (2.268Ω Max). They are direct electrical substitutes.

Q: Do these parts have identical physical dimensions?

A: Yes. Both parts use the 1812 (4532 Metric) package with identical dimensions of 0.177" L × 0.126" W (4.50mm × 3.20mm) and maximum seated height of 0.134" (3.40mm).

Q: What is the key difference between P1812-563K and P1812R-563K?

A: The primary difference is RoHS compliance status. The P1812R-563K is ROHS3 compliant, while the P1812-563K is RoHS non-compliant. All electrical and mechanical parameters remain identical.

Q: Can I use P1812R-563K in a design that originally specified P1812-563K?

A: Yes, provided your application requirements permit ROHS3 compliance adoption. There are no electrical or mechanical restrictions preventing this substitution.

Q: Which part should I select for new designs?

A: Selection depends on application compliance requirements. For systems requiring ROHS3 compliance, specify P1812R-563K. For systems without RoHS requirements, either part is acceptable based on availability and project specifications.
