AISC-1008-R027J-T Equivalent & Substitute Parts

Part Overview

The AISC-1008-R027J-T is a 27 nH unshielded drum core wirewound inductor manufactured by Abracon LLC, rated for 1 A continuous current with a maximum DC resistance of 130 mOhm. This surface mount component is designed for high-frequency applications up to 1.6 GHz self-resonant frequency and operates across the industrial temperature range of -40°C to 125°C. The part is ROHS3 compliant with MSL 1 rating, indicating unlimited moisture tolerance. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified parameter set.

Substitute Part Grouping Explanation

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

Inductance Value: 27 nH ±5% tolerance
Current Rating: 1 A minimum
DC Resistance: 130 mOhm maximum
Package / Case: 1008 (2520 Metric) surface mount
Shielding Configuration: Unshielded
Operating Temperature Range: Minimum -40°C to 125°C coverage
Q Factor & Self-Resonant Frequency: 55 @ 350 MHz and 1.6 GHz respectively

Both identified substitute parts meet these electrical and mechanical criteria. Substitution is valid when all parameters remain within specification limits and the component maintains functional equivalence in the target application circuit.

Engineering Selection Recommendations

All three parts maintain active product status with ROHS3 compliance and MSL 1 rating, confirming environmental and regulatory equivalence. The 36502C27NJTDG (TE Connectivity) carries AEC-Q200 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components. The LQW2UAS27NJ00L (Murata) extends the lower operating temperature limit to -55°C, offering expanded thermal range coverage compared to the primary part. Physical dimensions vary slightly across the three options, with the Murata part featuring the smallest footprint (2.62mm × 2.45mm × 2.03mm height) and the TE Connectivity part at intermediate dimensions (2.92mm × 2.79mm × 2.10mm height). Core material differs between the Abracon drum core ceramic construction and the TE Connectivity ceramic core versus the Murata air core design, though all maintain identical electrical performance specifications at the stated test frequency.

Frequently Asked Questions (FAQ)

Q: Can AISC-1008-R027J-T be directly replaced with 36502C27NJTDG?

A: Yes. Both parts share identical inductance (27 nH), current rating (1 A), DC resistance (130 mOhm max), package footprint (1008/2520 Metric), and operating temperature range (-40°C to 125°C). The TE Connectivity part is a direct electrical and mechanical substitute.

Q: What is the difference between the Abracon and Murata parts?

A: The primary electrical specifications are identical. The Murata LQW2UAS27NJ00L uses an air core design versus the Abracon ceramic drum core, and extends the minimum operating temperature to -55°C. Physical dimensions are slightly smaller on the Murata part. Both are ROHS3 compliant with MSL 1 rating.

Q: Does the TE Connectivity 36502C27NJTDG offer any additional benefits?

A: The TE Connectivity part carries AEC-Q200 automotive qualification, which may be required for automotive or high-reliability applications. All other electrical and mechanical parameters remain equivalent to the primary part.

Q: Are there packaging differences between these parts?

A: The primary part (AISC-1008-R027J-T) is supplied in Cut Tape (CT) packaging. Both substitute parts are supplied in Tape & Reel (TR) packaging, which is standard for higher-volume production environments. The component specifications remain unchanged.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, provided the PCB footprint accommodates the 1008 (2520 Metric) package. Minor dimensional variations exist: Abracon/TE Connectivity at 2.92mm × 2.79mm versus Murata at 2.62mm × 2.45mm. Height differences (2.29mm, 2.10mm, and 2.03mm respectively) are negligible for standard surface mount assembly.

Q: What compliance certifications apply to all three parts?

A: All three parts are ROHS3 compliant, carry MSL 1 (unlimited moisture sensitivity level), and are classified as EAR99 for export control purposes. The TE Connectivity part additionally holds AEC-Q200 automotive qualification.
