Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IMC1812ES100J are qualified based on the following critical parameters:

• Inductance Value: 10 µH with ±5% tolerance
• Current Rating: 250 mA minimum
• DC Resistance: 1.6 Ohm maximum
• Package / Case: 1812 (4532 Metric) surface mount
• Physical Dimensions: 0.177" L x 0.126" W (4.50mm x 3.20mm), Height 0.134" (3.40mm) maximum
• Shielding Configuration: Unshielded
• Frequency Characteristics: Q @ 2.52 MHz and Self Resonant Frequency @ 20 MHz
• Compliance: ROHS3 Compliant, REACH Unaffected

The substitute parts CM453232-100JL and PM1812-100J-RC meet these electrical and mechanical requirements. Both are manufactured by Bourns Inc., maintain identical inductance, current rating, and DC resistance specifications, and are packaged in the same 1812 form factor with equivalent physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active production components with full ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the original IMC1812ES100J.

CM453232-100JL operates across -40°C to 125°C with Moisture Sensitivity Level 1 (Unlimited), providing extended low-temperature performance and superior moisture handling characteristics.

PM1812-100J-RC operates across -40°C to 100°C with Moisture Sensitivity Level 3 (168 Hours), suitable for applications within this temperature range where standard moisture sensitivity protocols are acceptable.

Selection between these substitutes depends on the specific operating temperature range and moisture exposure requirements of the target application. Both maintain electrical equivalence across all specified parameters.

Frequently Asked Questions (FAQ)

Q: Can CM453232-100JL and PM1812-100J-RC be used interchangeably with IMC1812ES100J?

A: Yes, both parts meet the electrical and mechanical specifications of the IMC1812ES100J. Selection should account for operating temperature range and moisture sensitivity requirements specific to your application.

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

A: The IMC1812ES100J uses iron powder core material, while both Bourns substitutes use ferrite core material. Despite this material difference, all three parts deliver identical electrical performance at the specified frequency and current ratings.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three inductors share the same 1812 (4532 Metric) package with 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 layout compatibility.

Q: What are the operating temperature differences between the substitute parts?

A: IMC1812ES100J and CM453232-100JL both operate from -55°C to 125°C and -40°C to 125°C respectively. PM1812-100J-RC operates from -40°C to 100°C. Verify your application's temperature requirements before selection.

Q: Do all parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.
