IMC1812EB3R3J Equivalent & Substitute Parts

Part Overview

The IMC1812EB3R3J is a 3.3 µH unshielded drum core wirewound inductor manufactured by Vishay Dale, rated for 355 mA continuous current with 800mOhm maximum DC resistance. This surface mount component in 1812 (4532 Metric) package is designed for applications requiring fixed inductance in compact form factors. The part maintains active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to provide design flexibility, inventory alternatives, and sourcing options while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IMC1812EB3R3J is determined by strict equivalence across the following critical parameters:

• Inductance value: 3.3 µH
• Inductance tolerance: ±5%
• Current rating: 355 mA minimum
• DC resistance: 800mOhm maximum
• Package / Case: 1812 (4532 Metric)
• Mounting type: Surface Mount
• Q factor: 50 @ 7.96MHz
• Self-resonant frequency: 45MHz
• RoHS3 compliance status

The CM453232-3R3JL from Bourns Inc. meets all electrical specifications and mechanical requirements. Core material differs (Ferrite vs. Iron Powder) but does not affect substitution eligibility as both materials achieve identical electrical performance within specified parameters. Operating temperature range differs (-40°C ~ 125°C vs. -55°C ~ 125°C); applications requiring operation below -40°C must retain the original IMC1812EB3R3J.

Parameter Comparison

Engineering Selection Recommendations

Both the IMC1812EB3R3J and CM453232-3R3JL maintain active product status with full regulatory compliance. Selection between these parts is determined by application temperature requirements and packaging format availability.

The IMC1812EB3R3J supports extended low-temperature operation to -55°C and is supplied in Bulk packaging. The CM453232-3R3JL operates to -40°C minimum and is supplied in Tape & Reel format, suitable for automated assembly processes.

For applications operating below -40°C, the IMC1812EB3R3J is required. For applications within -40°C to 125°C range, either part is electrically and mechanically equivalent. Packaging format selection depends on procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can CM453232-3R3JL replace IMC1812EB3R3J in all applications?

A: CM453232-3R3JL is electrically and mechanically equivalent for applications operating within -40°C to 125°C. Applications requiring operation below -40°C must use IMC1812EB3R3J.

Q: What is the difference between Bulk and Tape & Reel packaging?

A: Bulk packaging is suitable for manual assembly and small-volume applications. Tape & Reel packaging is designed for automated pick-and-place assembly processes and high-volume production.

Q: Does core material affect substitution eligibility?

A: Core material differs between these parts (Iron Powder vs. Ferrite) but does not affect substitution eligibility. Both materials achieve identical electrical performance within the specified parameters of inductance, current rating, DC resistance, Q factor, and self-resonant frequency.

Q: Are both parts RoHS3 compliant?

A: Yes, both IMC1812EB3R3J and CM453232-3R3JL are ROHS3 compliant with REACH Unaffected status.

Q: What are the physical dimensions for PCB layout?

A: Both parts share identical dimensions: 0.177" L x 0.126" W (4.50mm x 3.20mm) with maximum seated height of 0.134" (3.40mm). PCB footprints are interchangeable.
