Substitute Part Grouping Explanation

Substitute parts for the AISC-1008-1R0J-T are qualified based on the following criteria:

• Inductance value: 1 µH (exact match required)
• Current rating: 370 mA (minimum requirement)
• Package / Case: 1008 (2520 Metric) (identical footprint)
• Mounting type: Surface Mount (identical assembly method)
• Operating temperature range: -40°C ~ 125°C (minimum coverage required)
• DC resistance: Maximum 1.8Ohm (functional tolerance)
• Tolerance: ±5% (specification match)
• Shielding: Unshielded (electrical characteristic match)
• RoHS3 compliance: Required for regulatory equivalence

Three substitute parts meet these criteria: 36502C1R0JTDG (TE Connectivity), 744758310A (Würth Elektronik), and LQW2UAS1R0J00L (Murata Electronics). Each maintains the core electrical specifications while offering variations in DC resistance, core material, and physical dimensions within acceptable limits.

Parameter Comparison

Engineering Selection Recommendations

All four parts maintain active product status and RoHS3 compliance, qualifying them for equivalent use in applications requiring 1 µH inductance at 370 mA. Selection between the AISC-1008-1R0J-T and its substitutes depends on specific application constraints:

The 36502C1R0JTDG (TE Connectivity) offers identical footprint dimensions and electrical performance with marginally lower DC resistance (1.75Ohm vs. 1.8Ohm), providing improved efficiency in power-sensitive applications. This part carries AEC-Q200 automotive qualification, suitable for automotive-grade applications.

The 744758310A (Würth Elektronik) provides the lowest DC resistance (1.7Ohm) and smallest physical footprint, beneficial for space-constrained designs. The reduced height (1.90mm) accommodates applications with strict vertical clearance requirements. REACH compliance is confirmed.

The LQW2UAS1R0J00L (Murata Electronics) features an air core design and extended operating temperature range (-55°C to 125°C), supporting applications requiring lower temperature operation. This part is suitable for industrial and extended-temperature environments.

Frequently Asked Questions (FAQ)

Q: Can AISC-1008-1R0J-T be directly replaced with any of these substitutes?

A: Yes, all three substitute parts are electrically and mechanically compatible within the defined parameters. They share identical inductance (1 µH), current rating (370 mA), package (1008/2520 Metric), and operating temperature range (-40°C to 125°C minimum). Physical dimensions vary slightly; verify PCB layout clearances before substitution.

Q: What is the difference in DC resistance between these parts?

A: The AISC-1008-1R0J-T has a maximum DC resistance of 1.8Ohm. Substitutes range from 1.7Ohm to 1.75Ohm maximum. Lower DC resistance reduces power dissipation and heat generation. Applications sensitive to resistive losses should prioritize the 744758310A (1.7Ohm).

Q: Are there temperature range differences?

A: The AISC-1008-1R0J-T, 36502C1R0JTDG, and 744758310A operate from -40°C to 125°C. The LQW2UAS1R0J00L extends to -55°C minimum, supporting colder operating environments. All meet or exceed the standard range.

Q: What is the significance of core material differences?

A: The AISC-1008-1R0J-T, 36502C1R0JTDG, and 744758310A use ceramic cores. The LQW2UAS1R0J00L uses an air core. Both designs achieve the specified 1 µH inductance and electrical performance. Core material selection affects frequency response and Q factor characteristics but does not impact substitution eligibility for this application.

Q: Do physical dimension variations affect PCB assembly?

A: All parts use the 1008 (2520 Metric) package with identical footprint. Height variations (1.90mm to 2.29mm) may affect clearance to adjacent components or conformal coating processes. Verify board layout and assembly specifications before substitution, particularly for the 744758310A (lowest profile at 1.90mm).

Q: Are all parts RoHS3 compliant?

A: Yes, all four parts are RoHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting standard environmental and regulatory requirements.

Q: Which substitute offers the best inventory availability?

A: The 36502C1R0JTDG (TE Connectivity) has the highest stock level at 4747 units, followed by 744758310A (Würth Elektronik) at 2913 units and LQW2UAS1R0J00L (Murata Electronics) at 2414 units.
