AISC-1008-R056J-T Equivalent & Substitute Parts

Part Overview

The AISC-1008-R056J-T is a 56 nH unshielded drum core wirewound inductor manufactured by Abracon LLC, rated for 1 A continuous current with a maximum DC resistance of 180 mOhm. This surface mount component operates across the temperature range of -40°C to 125°C and is designed for high-frequency applications up to 1.3 GHz self-resonant frequency. The part is currently in active production status and ROHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Engineering Selection Recommendations

AISC-1008-R056J-T (Primary Part): Recommended for applications requiring ROHS3 compliance. Active production status with established supply chain. Suitable for consumer and industrial applications with environmental compliance requirements.

36502C56NJTDG (TE Connectivity Alternative): Qualified as a direct electrical substitute with identical inductance, current rating, and DC resistance specifications. Features higher Q factor (65 vs. 50 at 350 MHz) and AEC-Q200 automotive qualification. Note: RoHS non-compliant status requires design review for regulatory applicability. Suitable for automotive and high-reliability applications where AEC-Q200 certification is required.

LQW2UAS56NJ00L (Murata Recommended Alternative): Qualified as a direct electrical substitute with identical core electrical parameters. ROHS3 compliant. Extended operating temperature range (-55°C to 125°C) provides additional thermal margin. Slightly smaller physical dimensions (2.62mm x 2.45mm vs. 2.92mm x 2.79mm) with lower seated height (2.03mm vs. 2.29mm). Suitable for space-constrained applications and extended temperature environments.

Frequently Asked Questions (FAQ)

Q: Can 36502C56NJTDG be used as a direct replacement for AISC-1008-R056J-T?

A: Electrical substitution is valid based on matching inductance (56 nH), current rating (1 A), DC resistance (180 mOhm max), and package (1008). However, RoHS compliance status differs. Design review is required to confirm regulatory applicability for your end application.

Q: What is the difference in Q factor between the main part and substitutes?

A: The AISC-1008-R056J-T has Q of 50 at 350 MHz, while both 36502C56NJTDG and LQW2UAS56NJ00L have Q of 65 at 350 MHz. Higher Q indicates lower losses at the test frequency. Application-specific performance validation is necessary if Q factor is a critical design parameter.

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

A: All three parts use the 1008 (2520 Metric) package and surface mount configuration. Physical dimensions vary slightly: AISC-1008-R056J-T and 36502C56NJTDG are 2.92mm x 2.79mm, while LQW2UAS56NJ00L is 2.62mm x 2.45mm. Seated heights also differ (2.29mm, 2.10mm, and 2.03mm respectively). Verify PCB layout clearances for the selected substitute.

Q: Which substitute is recommended for RoHS-compliant designs?

A: Both AISC-1008-R056J-T and LQW2UAS56NJ00L are ROHS3 compliant. The 36502C56NJTDG is RoHS non-compliant and requires design review before use in regulated applications.

Q: What is the operating temperature range for each part?

A: AISC-1008-R056J-T and 36502C56NJTDG operate from -40°C to 125°C. LQW2UAS56NJ00L extends to -55°C to 125°C, providing additional low-temperature margin for harsh environment applications.
