Substitute Part Grouping Explanation
Substitution eligibility for the 1008HC-222EJFS is determined by the following critical parameters:
Primary Matching Criteria:
- Inductance value: 2.2 µH (±5% tolerance)
- Package designation: 1008 (2520 Metric)
- Core material: Ferrite
- Shielding configuration: Unshielded
- Mounting type: Surface Mount
Secondary Compatibility Parameters:
- Current rating: Minimum 500 mA (equal or greater)
- DC resistance: Acceptable range based on application thermal and efficiency requirements
- Operating temperature range: Minimum -40°C to 85°C coverage
- Inductance test frequency: 7.96 MHz or equivalent
Substitute parts are classified into two categories:
Direct Substitutes: Parts meeting all primary matching criteria with current ratings equal to or exceeding 500 mA, enabling direct replacement without circuit redesign.
Similar Substitutes: Parts meeting all primary matching criteria but with current ratings below 500 mA, requiring application-level verification before implementation.

Engineering Selection Recommendations
Direct Substitutes (Recommended for Primary Selection):
The 744758322A (Würth Elektronik, WE-RFH series) and AISC-1008F-2R2J-T (Abracon LLC, AISC-1008F series) are direct substitutes for the 1008HC-222EJFS. Both parts maintain the 2.2 µH inductance specification, 1008 package format, and support current ratings of 520 mA, exceeding the original 500 mA requirement. Both are ROHS3 compliant and operate within the -40°C to 85°C temperature range.
The 744758322A is supplied in Tape & Reel (TR) packaging with 3300 pieces in stock inventory. The AISC-1008F-2R2J-T is supplied in Cut Tape (CT) & Digi-Reel® packaging with 1051 pieces in stock inventory.
Similar Substitutes (Application-Dependent Selection):
The NLV25T-2R2J-EFD (TDK Corporation, NLV-EFD series) and NLV25T-2R2J-EF (TDK Corporation, NLV-EF series) maintain the 2.2 µH inductance and 1008 package specification. However, both parts are rated for 200 mA continuous current, which is below the original 500 mA specification. These parts are suitable only for applications where the actual operating current does not exceed 200 mA.
The NLV25T-2R2J-EFD includes AEC-Q200 automotive qualification and is supplied in Tape & Reel (TR) packaging with 2682 pieces in stock. The NLV25T-2R2J-EF is supplied in Cut Tape (CT) & Digi-Reel® packaging with 1053 pieces in stock. Both support an extended operating temperature range of -40°C to 105°C.
All substitute parts are ROHS3 compliant and REACH unaffected or affected as specified in individual part documentation.
Frequently Asked Questions (FAQ)
Q: Can the 744758322A directly replace the 1008HC-222EJFS without circuit modification?
A: Yes. The 744758322A matches the 2.2 µH inductance, 1008 package, and exceeds the 500 mA current rating with 520 mA capability. No circuit redesign is required for direct substitution.
Q: What is the difference between the NLV25T-2R2J-EFD and NLV25T-2R2J-EF?
A: Both parts are electrically identical with 2.2 µH inductance, 200 mA current rating, and 1.55 Ohm maximum DCR. The primary difference is packaging: NLV25T-2R2J-EFD is supplied in Tape & Reel (TR) format, while NLV25T-2R2J-EF is supplied in Cut Tape (CT) & Digi-Reel® format. The NLV25T-2R2J-EFD includes AEC-Q200 automotive qualification.
Q: Why do the TDK parts (NLV series) have lower current ratings than the original part?
A: The NLV25T-2R2J-EFD and NLV25T-2R2J-EF are rated for 200 mA continuous current, compared to the 1008HC-222EJFS 500 mA rating. These parts are classified as similar substitutes and are suitable only for applications where actual operating current remains below 200 mA.
Q: Are all substitute parts RoHS compliant?
A: Yes. All substitute parts listed are ROHS3 compliant. The NLV25T-2R2J-EFD and NLV25T-2R2J-EF are REACH affected, while the 744758322A and AISC-1008F-2R2J-T are REACH unaffected.
Q: What is the impact of higher DC resistance in substitute parts?
A: The 1008HC-222EJFS has 600 mOhm DCR, while direct substitutes have 1.1 to 1.15 Ohm DCR. Higher DCR increases resistive losses and heat dissipation. Applications sensitive to inductor losses or thermal performance should evaluate the impact of increased DCR on circuit efficiency and thermal management.
Q: Can I use the AISC-1008F-2R2J-T in automotive applications?
A: The AISC-1008F-2R2J-T does not include automotive qualification markings in the provided specifications. For automotive applications requiring AEC-Q200 qualification, the NLV25T-2R2J-EFD is the appropriate selection, subject to current rating verification.
Q: What packaging options are available for high-volume production?
A: The 744758322A is supplied in Tape & Reel (TR) format with 3300 pieces in stock, suitable for automated assembly. The NLV25T-2R2J-EFD is also available in Tape & Reel (TR) format with 2682 pieces in stock. The AISC-1008F-2R2J-T and NLV25T-2R2J-EF are supplied in Cut Tape (CT) & Digi-Reel® format.
