Engineering Selection Recommendations

744758356A (Würth Elektronik WE-RFH Series)

This substitute provides the closest electrical performance match to the 1008HS-562EKFS. The 370 mA current rating exceeds the original 300 mA specification, accommodating higher current applications. DC resistance of 1.8Ohm Max represents a 33% increase over the original 1.35Ohm, which may introduce additional thermal dissipation in current-limited circuits. The part maintains identical operating temperature range (-40°C ~ 85°C) and is ROHS3 compliant with REACH Unaffected status. Physical dimensions are slightly smaller, ensuring PCB layout compatibility. Active product status guarantees long-term availability.

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

This substitute is suitable for applications where current requirements do not exceed 170 mA. The ±5% inductance tolerance provides tighter specification control compared to the original ±10%. DC resistance of 2.5Ohm Max represents a significant increase and is applicable only to low-current circuits where resistive losses are non-critical. Extended operating temperature range (-40°C ~ 105°C) provides thermal margin beyond the original specification. Active product status and ROHS3 compliance are confirmed. REACH Affected status requires verification for supply chain compliance in regulated markets.

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

This substitute is functionally equivalent to NLV25T-5R6J-EF with the addition of AEC-Q200 automotive qualification. Selection is appropriate for applications requiring automotive-grade reliability and traceability. Current rating limitation of 170 mA restricts use to low-current circuits. All other electrical and mechanical parameters are identical to the NLV25T-5R6J-EF variant. REACH Affected status applies.

Selection Logic:

For applications requiring 300+ mA current capacity: Select 744758356A
For applications with current ≤ 170 mA and standard industrial requirements: Select NLV25T-5R6J-EF
For applications with current ≤ 170 mA and automotive qualification requirements: Select NLV25T-5R6J-EFD

Frequently Asked Questions (FAQ)

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

A: 744758356A is electrically compatible for applications operating at or below 300 mA. The increased DC resistance (1.8Ohm vs. 1.35Ohm) results in higher power dissipation. Verify thermal performance in power-sensitive circuits. Physical dimensions are smaller, confirming PCB footprint compatibility.

Q: Why do TDK substitutes have lower current ratings (170 mA)?

A: NLV25T-5R6J-EF and NLV25T-5R6J-EFD are rated for 170 mA maximum current. These parts are suitable only for circuits operating below this threshold. Applications requiring 300 mA operation must use 744758356A.

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

A: Higher DC resistance increases resistive losses (I²R heating). In the 744758356A, DCR increases from 1.35Ohm to 1.8Ohm. In TDK parts, DCR increases to 2.5Ohm. Thermal analysis is required for circuits sensitive to inductor losses. Low-current applications are less affected.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitutes (744758356A, NLV25T-5R6J-EF, NLV25T-5R6J-EFD) are ROHS3 compliant, matching the original 1008HS-562EKFS specification.

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

A: Both parts are electrically and mechanically identical. NLV25T-5R6J-EFD includes AEC-Q200 automotive qualification rating. Select the EFD variant for automotive applications requiring qualification traceability.

Q: Do substitute parts fit the same PCB footprint?

A: All substitutes use the 1008 (2520 Metric) package. Physical dimensions vary slightly: 744758356A measures 0.102" L x 0.083" W; TDK parts measure 0.098" L x 0.079" W. The original measures 0.115" L x 0.110" W. Smaller substitute dimensions ensure compatibility with existing PCB layouts designed for the original part.

Q: What is REACH Affected status?

A: REACH Affected indicates the part is subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. Verify supply chain compliance requirements in your region. 744758356A has REACH Unaffected status, simplifying regulatory compliance in certain markets.

Q: Is inventory availability a selection factor?

A: Inventory levels are provided for reference: 744758356A (1674 Pcs), NLV25T-5R6J-EF (2300 Pcs), NLV25T-5R6J-EFD (739 Pcs). Verify current stock with suppliers for production scheduling.
