Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1008HS-562EJFS is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 5.6 µH (±5% tolerance)
• Package / Case: 1008 (2520 Metric)
• Core type: Ferrite, unshielded drum core wirewound
• Mounting type: Surface Mount
• RoHS3 compliance

Secondary Compatibility Factors:

• Current rating: Substitute must equal or exceed 300 mA
• DC resistance: Substitute DCR must not exceed design limits for the application
• Operating temperature range: Substitute must support -40°C minimum
• Moisture sensitivity: MSL 1 rating required

The substitute parts listed below maintain the core inductance specification and package footprint while offering variations in current handling capability and DC resistance characteristics. Selection depends on application-specific current and thermal requirements.

Parameter Comparison

Engineering Selection Recommendations

744758356A (Würth Elektronik WE-RFH Series)

This part is the primary direct substitute for the 1008HS-562EJFS. It maintains identical inductance (5.6 µH), tolerance (±5%), package (1008/2520 Metric), and operating temperature range (-40°C to 85°C). The 744758356A offers superior current handling at 370 mA versus the original 300 mA specification, providing design margin for applications with variable load conditions. DC resistance increases to 1.8Ohm maximum, which must be evaluated against circuit thermal and efficiency requirements. The part is active in production with ROHS3 compliance and MSL 1 rating. Würth Elektronik maintains consistent supply availability.

NLV25T-5R6J-EF (TDK NLV-EF Series)

This TDK part shares the 5.6 µH inductance, ±5% tolerance, and 1008 package footprint. However, the current rating is reduced to 170 mA, making this substitute suitable only for applications with current requirements below 170 mA. DC resistance increases to 2.5Ohm maximum. The extended operating temperature range (-40°C to 105°C) provides thermal margin beyond the original specification. Product status is active with ROHS3 compliance. REACH status is affected, requiring compliance verification for regulated markets.

NLV25T-5R6J-EFD (TDK NLV-EFD Series)

This variant is electrically identical to NLV25T-5R6J-EF with 170 mA current rating and 2.5Ohm maximum DCR. The NLV-EFD series includes AEC-Q200 automotive qualification, extending application scope to automotive and high-reliability environments. Operating temperature range extends to 105°C. Product status is active with ROHS3 compliance. REACH status is affected. This part is recommended for applications requiring automotive-grade component certification.

Selection Logic:

For applications requiring the full 300 mA current specification, 744758356A is the recommended substitute. For current-limited applications below 170 mA, either TDK part is acceptable, with NLV25T-5R6J-EFD preferred for automotive or high-reliability applications. All substitutes maintain package compatibility and RoHS3 compliance with the original part.

Frequently Asked Questions (FAQ)

Q: Can 744758356A directly replace 1008HS-562EJFS in all applications?

A: 744758356A is mechanically and electrically compatible for applications operating at or below 300 mA. The increased current rating (370 mA) and slightly higher DCR (1.8Ohm max vs. 1.35Ohm) must be evaluated against circuit thermal dissipation and efficiency requirements. Both parts share identical inductance, tolerance, package, and operating temperature range.

Q: Why do the TDK parts have lower current ratings?

A: NLV25T-5R6J-EF and NLV25T-5R6J-EFD are rated for 170 mA maximum continuous current. These parts are suitable only for applications with current requirements at or below 170 mA. Higher current operation will cause saturation and performance degradation.

Q: What is the difference between NLV25T-5R6J-EF and NLV25T-5R6J-EFD?

A: Both parts are electrically identical with 5.6 µH inductance, 170 mA current rating, and 2.5Ohm maximum DCR. The primary difference is that NLV25T-5R6J-EFD includes AEC-Q200 automotive qualification. Select NLV25T-5R6J-EFD for automotive, medical, or high-reliability applications requiring automotive-grade certification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitutes (744758356A, NLV25T-5R6J-EF, NLV25T-5R6J-EFD) are ROHS3 compliant. The original 1008HS-562EJFS is also ROHS3 compliant.

Q: What is the impact of increased DC resistance in substitute parts?

A: The 1008HS-562EJFS has 1.35Ohm DCR. Substitute 744758356A increases to 1.8Ohm maximum, and TDK parts increase to 2.5Ohm maximum. Higher DCR results in increased resistive losses and heat generation at rated current. Circuit thermal analysis is required to confirm acceptable performance, particularly in high-frequency or high-current applications.

Q: Do all parts use the same 1008 (2520 Metric) package?

A: Yes. All parts use the 1008 (2520 Metric) surface mount package. Physical footprint and land pattern compatibility are maintained across all substitutes. Dimensional variations exist in height and exact length/width measurements, but these fall within standard PCB assembly tolerances for the 1008 package class.

Q: What is MSL 1 rating and why is it important?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life with no moisture precautions required. All listed parts carry MSL 1 rating, eliminating moisture-related handling and storage constraints during manufacturing and assembly.

Q: Can I use NLV25T-5R6J-EFD in non-automotive applications?

A: Yes. NLV25T-5R6J-EFD is suitable for any application within its electrical and thermal specifications. AEC-Q200 qualification is an additional certification that does not restrict use in non-automotive applications. However, the 170 mA current limit must be observed.

Q: What is the difference between Tape & Reel (TR) packaging and the original packaging?

A: All substitute parts are supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly. The original 1008HS-562EJFS packaging is not specified in the provided data. TR packaging is compatible with automated pick-and-place equipment and is the industry standard for SMD components.
