IMC0805ER56NJ Equivalent & Substitute Parts

Part Overview

The IMC0805ER56NJ is a 56 nH unshielded wirewound inductor manufactured by Vishay Dale, rated for 360 mA with a maximum DC resistance of 390mOhm in a 0805 (2012 Metric) surface mount package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution for the IMC0805ER56NJ is determined by the following critical parameters:

Inductance Value: 56 nH (must match exactly within ±5% tolerance)
Package / Case: 0805 (2012 Metric) surface mount (physical and electrical compatibility)
Current Rating: Minimum 360 mA (substitute must support or exceed the original rating)
DC Resistance: Lower or equal DCR values are preferred to maintain circuit performance
Operating Temperature Range: Must support -40°C ~ 105°C minimum
Shielding: Unshielded configuration maintained across substitutes

Two active substitute parts meet these criteria: IMC0805ER56NJ01 (Vishay Dale) and CE201210-56NJ (Bourns Inc.). Both maintain the same inductance value, package size, and operating temperature range while offering improved electrical characteristics.

Engineering Selection Recommendations

IMC0805ER56NJ01 is the manufacturer-recommended substitute from Vishay Dale. This part maintains the same inductance, tolerance, and operating temperature range while offering superior electrical performance: 500 mA current rating (139% of original), 250mOhm DCR (64% of original), and improved Q factor (60 @ 500MHz vs. 15 @ 100MHz). The reduced height (1.40mm vs. 1.55mm) provides better PCB layout compatibility. Product status is active with full availability.

CE201210-56NJ from Bourns Inc. is an alternative substitute with active product status and extended operating temperature range (-55°C ~ 125°C). This part maintains the 56 nH inductance and ±5% tolerance. However, the current rating is 300 mA (below the original 360 mA specification) and DCR is 750mOhm (1.92x higher than original). This substitute is suitable only for applications where current requirements do not exceed 300 mA and where higher DCR is acceptable. The lowest profile (1.03mm) offers maximum PCB space efficiency.

Both substitutes are ROHS3 compliant and maintain unshielded configuration. Selection depends on circuit current requirements and DCR sensitivity.

Frequently Asked Questions (FAQ)

Q: Can IMC0805ER56NJ01 be used as a direct replacement for IMC0805ER56NJ?

A: Yes. Both parts share identical inductance (56 nH), tolerance (±5%), operating temperature range (-40°C ~ 105°C), and 0805 package dimensions. IMC0805ER56NJ01 exceeds the original current rating and provides lower DCR, making it a superior substitute from Vishay Dale.

Q: What are the limitations of CE201210-56NJ as a substitute?

A: CE201210-56NJ has a maximum current rating of 300 mA, which is below the original 360 mA specification. Additionally, its DC resistance is 750mOhm, significantly higher than the original 390mOhm. This substitute is only suitable for circuits where current does not exceed 300 mA and where increased DCR does not degrade performance.

Q: Are all three parts physically compatible with the same PCB footprint?

A: Yes. All three parts use the 0805 (2012 Metric) surface mount package with identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm). Heights differ slightly: IMC0805ER56NJ (1.55mm), IMC0805ER56NJ01 (1.40mm), and CE201210-56NJ (1.03mm). These height variations do not affect footprint compatibility but may impact clearance in space-constrained designs.

Q: Why does inductance value remain constant across all substitutes?

A: The 56 nH inductance is the functional requirement of the circuit. All substitutes maintain this value within ±5% tolerance to ensure equivalent electrical behavior in the application.

Q: What is the difference between wirewound and multilayer inductor construction?

A: IMC0805ER56NJ uses wirewound construction with non-magnetic core. IMC0805ER56NJ01 uses drum core wirewound with ceramic core. CE201210-56NJ uses multilayer construction with ceramic core. These construction differences result in different Q factors, self-resonant frequencies, and DCR characteristics, but all maintain the same 56 nH inductance value.

Q: Are there compliance or certification differences between substitutes?

A: All three parts are ROHS3 compliant and REACH unaffected. IMC0805ER56NJ01 compliance status is not specified in available data. CE201210-56NJ explicitly lists ROHS3 compliance. For applications requiring specific certifications, verify IMC0805ER56NJ01 compliance documentation with Vishay Dale.
