IMC1812EB820J Equivalent & Substitute Parts

Part Overview

The IMC1812EB820J is a 82 µH unshielded drum core wirewound inductor manufactured by Vishay Dale, rated for 120 mA maximum current with 7Ohm maximum DC resistance. This surface mount component operates across the temperature range of -55°C to 125°C and is designed for applications requiring fixed inductance in compact 1812 (4532 Metric) package form factor. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the same package footprint and critical performance parameters, ensuring direct replacement capability in existing circuit designs.

Substitute Part Grouping Explanation

Substitution eligibility for the IMC1812EB820J is determined by strict equivalence across the following critical parameters:

• Inductance value: 82 µH with ±5% tolerance
• Current rating: 120 mA minimum
• DC resistance: 7Ohm maximum
• Package footprint: 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
• Frequency characteristics: Q factor of 50 @ 2.52MHz and self resonant frequency of 8MHz
• Regulatory compliance: ROHS3 compliant, REACH unaffected

The PM1812-820J-RC from Bourns Inc. meets all specified electrical and mechanical parameters, enabling direct substitution in applications where the IMC1812EB820J is currently specified.

Parameter Comparison

Engineering Selection Recommendations

The PM1812-820J-RC qualifies as a direct substitute for the IMC1812EB820J based on complete electrical and mechanical parameter equivalence. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent applications.

The operating temperature range of the PM1812-820J-RC (-40°C to 100°C) is a subset of the IMC1812EB820J range (-55°C to 125°C). Component selection should account for specific application temperature requirements. For applications operating within the -40°C to 100°C window, the Bourns part provides full functional equivalence. Applications requiring operation below -40°C or above 100°C must retain the Vishay Dale part.

Both components are currently in active production status with established supply availability.

Frequently Asked Questions (FAQ)

Q: Can the PM1812-820J-RC replace the IMC1812EB820J in all applications?

A: The PM1812-820J-RC provides electrical and mechanical equivalence for applications operating within the -40°C to 100°C temperature range. Applications requiring operation outside this range, particularly below -40°C or above 100°C, must use the IMC1812EB820J to ensure specified performance.

Q: Are the physical footprints identical?

A: Yes. Both components use the 1812 (4532 Metric) package with identical dimensions: 0.177" L x 0.126" W (4.50mm x 3.20mm) and maximum seated height of 0.134" (3.40mm). PCB layout and assembly processes require no modification.

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

A: The IMC1812EB820J uses an iron powder core, while the PM1812-820J-RC uses a ferrite core. Both achieve the specified inductance value, tolerance, Q factor, and self resonant frequency within the defined electrical parameters.

Q: Are both parts RoHS compliant?

A: Yes. Both the IMC1812EB820J and PM1812-820J-RC are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What packaging formats are available?

A: The IMC1812EB820J is supplied in Bulk packaging. The PM1812-820J-RC is supplied in Tape & Reel (TR) format. Packaging format selection depends on assembly process requirements and order quantity considerations.
