Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IMC1812EB2R2J is determined by strict equivalence across the following critical parameters:

• Inductance Value: 2.2 µH (exact match required)
• Inductance Tolerance: ±5% (matching tolerance band)
• Current Rating: 380 mA minimum (equal or higher acceptable)
• DC Resistance: 700mOhm maximum (equal or lower acceptable)
• Package / Case: 1812 (4532 Metric) (exact mechanical compatibility)
• Mounting Type: Surface Mount (identical assembly method)
• Shielding Configuration: Unshielded (same electromagnetic profile)
• Operating Temperature Range: Must support application requirements
• Compliance Standards: RoHS3 and REACH status alignment

The PM1812-2R2J-RC from Bourns Inc. qualifies as a direct substitute based on matching inductance, tolerance, current rating, DC resistance, package dimensions, and surface mount configuration. Both components maintain identical electrical performance specifications at the test frequency of 7.96 MHz and equivalent Q factor ratings.

Engineering Selection Recommendations

Both the IMC1812EB2R2J and PM1812-2R2J-RC maintain active product status with full regulatory compliance. Selection between these components should be based on application-specific temperature requirements. The IMC1812EB2R2J provides extended low-temperature operation to -55°C and high-temperature operation to 125°C, while the PM1812-2R2J-RC operates within -40°C to 100°C. For applications requiring the full temperature envelope of -55°C to 125°C, the IMC1812EB2R2J is the appropriate choice. For applications within the -40°C to 100°C range, either component is functionally equivalent. Both components carry identical electrical specifications, mechanical compatibility, and regulatory certifications, ensuring interchangeability within their respective temperature operating ranges.

Frequently Asked Questions (FAQ)

Q: Can PM1812-2R2J-RC replace IMC1812EB2R2J in all applications?

A: PM1812-2R2J-RC is electrically and mechanically equivalent to IMC1812EB2R2J for applications operating within -40°C to 100°C. Applications requiring operation below -40°C or above 100°C must use IMC1812EB2R2J to maintain specified performance within the full -55°C to 125°C range.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components are packaged in the 1812 (4532 Metric) case with identical dimensions of 0.177" L x 0.126" W (4.50mm x 3.20mm) and maximum seated height of 0.134" (3.40mm), ensuring direct PCB footprint compatibility.

Q: What is the difference in core material between these inductors?

A: IMC1812EB2R2J uses an iron powder drum core, while PM1812-2R2J-RC uses a ferrite core. Despite this material difference, both achieve identical inductance, tolerance, current rating, DC resistance, and frequency characteristics at the specified test conditions.

Q: Are both parts RoHS3 compliant?

A: Yes. Both IMC1812EB2R2J and PM1812-2R2J-RC are ROHS3 compliant with REACH unaffected status, meeting current environmental and regulatory requirements.

Q: What packaging formats are available for these parts?

A: IMC1812EB2R2J is supplied in Bulk packaging, while PM1812-2R2J-RC is supplied in Tape & Reel (TR) format. Packaging selection depends on assembly process requirements and order quantities.
