Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1008HC-223EJFS is determined by the following mandatory parameters:

Core Substitution Criteria:

• Inductance value: 22 µH (exact match required)
• Inductance tolerance: ±5% (matching tolerance)
• Core material: Ferrite drum core, unshielded (same construction type)
• Package / Case: 1008 (2520 Metric) (identical footprint)
• Mounting type: Surface Mount (same assembly method)

Electrical Performance Criteria:

• Current rating must equal or exceed 200 mA
• DC resistance must be compatible with circuit design requirements
• Operating temperature range must encompass -40°C ~ 85°C minimum
• Self-resonant frequency and Q factor are secondary performance indicators

Compliance Criteria:

• RoHS3 compliance required
• MSL rating of 1 (Unlimited) preferred for storage flexibility

The substitute parts listed below satisfy the core substitution criteria. However, variations in current rating and DC resistance exist and must be evaluated against specific circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

Würth Elektronik 744762422A: This substitute maintains identical inductance, tolerance, core type, package, and operating temperature range. However, the current rating of 110 mA is below the 200 mA specification of the main part. This part is suitable only for applications where the actual operating current does not exceed 110 mA. The increased DC resistance of 5 Ohm (versus 2.8 Ohm) results in higher power dissipation and must be evaluated against thermal design constraints.

TDK NLV25T-220J-EF: This substitute maintains identical inductance, tolerance, core type, and package. The current rating of 125 mA is below the 200 mA specification. The operating temperature range extends to 105°C, providing additional thermal margin. The DC resistance of 5.5 Ohm Max is higher than the main part. This part is suitable for applications where operating current does not exceed 125 mA and where extended temperature operation is beneficial.

TDK NLV25T-220J-EFD: This substitute is functionally equivalent to NLV25T-220J-EF with identical electrical specifications. The addition of AEC-Q200 automotive qualification provides enhanced reliability documentation. Current rating of 125 mA remains below the 200 mA specification. This part is suitable for applications requiring automotive-grade component certification where operating current does not exceed 125 mA.

Selection Guidance: All substitute parts are active products with established supply chains. Selection depends on circuit current requirements. If the application requires the full 200 mA rating, none of the listed substitutes provide direct replacement capability. If actual operating current is 125 mA or below, the TDK parts (NLV25T-220J-EF or NLV25T-220J-EFD) are preferred due to higher inventory availability and extended operating temperature range. The AEC-Q200 rated NLV25T-220J-EFD is recommended for automotive applications.

Frequently Asked Questions (FAQ)

Q: Can the 744762422A substitute for the 1008HC-223EJFS in all applications?

A: No. The 744762422A has a current rating of 110 mA, which is below the 200 mA rating of the main part. Substitution is valid only if the actual circuit operating current does not exceed 110 mA. The increased DC resistance (5 Ohm versus 2.8 Ohm) must also be verified against circuit design requirements.

Q: What is the difference between NLV25T-220J-EF and NLV25T-220J-EFD?

A: Both parts have identical electrical specifications: 22 µH inductance, 125 mA current rating, and 5.5 Ohm Max DC resistance. The primary difference is that NLV25T-220J-EFD carries AEC-Q200 automotive qualification. Selection between these parts depends on whether automotive-grade certification is required for the application.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and carry MSL rating of 1 (Unlimited), matching the compliance profile of the main part.

Q: Can I use a substitute part with lower current rating if my circuit only draws 100 mA?

A: Yes, provided the actual operating current does not exceed the substitute part's current rating. However, verify that the increased DC resistance of the substitute part does not negatively impact circuit performance or thermal design. The 744762422A (5 Ohm) and TDK parts (5.5 Ohm) have significantly higher DC resistance than the main part (2.8 Ohm), resulting in increased power dissipation.

Q: What is the package compatibility between the main part and substitutes?

A: All parts use the 1008 (2520 Metric) surface mount package with identical footprint. Physical dimensions vary slightly: the main part is 0.115" L x 0.110" W x 0.083" H, while substitute parts are slightly smaller (0.098" to 0.102" L x 0.079" to 0.083" W x 0.075" H). These dimensional variations are within standard PCB design tolerances for 1008 package placement.

Q: Why is the main part obsolete if substitutes are available?

A: The 1008HC-223EJFS is classified as obsolete by Delta Electronics/Components, indicating the manufacturer has discontinued production. Active substitute parts from Würth Elektronik and TDK Corporation provide functional alternatives with established supply chains and ongoing manufacturing support.

Q: Which substitute has the best availability?

A: NLV25T-220J-EF (TDK) has the highest inventory level at 37,100 pieces, followed by NLV25T-220J-EFD (TDK) at 4,237 pieces and 744762422A (Würth) at 3,910 pieces. All three substitutes are in active production with established distribution channels.
