Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1210HS-562EMFS is determined by the following mandatory parameters:

Core Compatibility Criteria:

• Inductance value: 5.6 µH (exact match required)
• Inductance tolerance: ±20% or tighter
• Core type: Ferrite drum core, wirewound, unshielded
• Package: 1210 (3225 Metric) surface mount

Electrical Performance Criteria:

• Current rating: Equal to or greater than 250 mA
• DC resistance: Equal to or less than 1.3Ohm (lower DCR preferred for reduced losses)
• Operating temperature: Minimum -40°C ~ 85°C coverage

Compliance & Environmental Criteria:

• RoHS3 compliance required
• Moisture Sensitivity Level 1 (Unlimited)
• Surface mount compatible footprint

Three substitute parts meet these criteria with active product status and improved or equivalent electrical performance.

Parameter Comparison

Engineering Selection Recommendations

7440320056 (Würth Elektronik WE-LQ Series)

This substitute provides superior electrical performance with 440 mA current rating (76% higher than the original 250 mA specification) and significantly reduced DC resistance of 360mOhm maximum (compared to 1.3Ohm). The extended operating temperature range (-40°C ~ 125°C) exceeds the original specification. Active product status with ROHS3 compliance and MSL 1 rating ensures long-term availability and supply chain stability. Tape & Reel packaging supports high-volume production environments.

NLV32T-5R6J-EF (TDK Corporation NLV-EF Series)

This substitute maintains electrical compatibility with tighter inductance tolerance (±5% versus ±20%), though current rating is limited to 200 mA (below the original 250 mA). DC resistance of 1.6Ohm maximum is within acceptable range. Active product status with ROHS3 compliance and extended operating temperature (-40°C ~ 105°C) provides design flexibility. Cut Tape and Digi-Reel® packaging options support both prototype and production workflows.

NLV32T-5R6J-EFD (TDK Corporation NLV-EFD Series)

Functionally identical to NLV32T-5R6J-EF with AEC-Q200 automotive qualification rating. Tape & Reel packaging is optimized for automated assembly. Identical electrical specifications and compliance certifications apply. Selection of this variant is appropriate for automotive or mission-critical applications requiring automotive-grade component qualification.

Frequently Asked Questions (FAQ)

Q: Can 7440320056 directly replace 1210HS-562EMFS in all applications?

A: Yes, within the electrical and thermal operating envelope. The 7440320056 exceeds the original current rating (440 mA vs. 250 mA) and provides lower DC resistance (360mOhm vs. 1.3Ohm), resulting in reduced power dissipation. The extended temperature range (-40°C ~ 125°C) covers the original specification (-40°C ~ 85°C). Mechanical footprint compatibility is confirmed (both 1210/3225 Metric package). Verify circuit design does not depend on the higher DCR of the original part.

Q: Why do the TDK NLV32T-5R6J series parts have lower current ratings?

A: The NLV32T-5R6J-EF and NLV32T-5R6J-EFD are rated for 200 mA maximum current, which is below the original 250 mA specification. These parts are suitable only for applications where the actual circuit current does not exceed 200 mA. If the design requires 250 mA or higher current capability, the Würth 7440320056 is the appropriate substitute.

Q: What is the difference between NLV32T-5R6J-EF and NLV32T-5R6J-EFD?

A: Both parts are electrically identical with 5.6 µH inductance, ±5% tolerance, 200 mA current rating, and 1.6Ohm maximum DCR. The primary difference is packaging: NLV32T-5R6J-EF is supplied in Cut Tape (CT) and Digi-Reel® formats, while NLV32T-5R6J-EFD is supplied in Tape & Reel (TR) format. NLV32T-5R6J-EFD includes AEC-Q200 automotive qualification. Select based on assembly process requirements and application standards.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All three substitute parts (7440320056, NLV32T-5R6J-EF, and NLV32T-5R6J-EFD) are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the original 1210HS-562EMFS compliance profile.

Q: What is the mechanical compatibility of these substitutes?

A: All substitute parts use the 1210 (3225 Metric) surface mount package with identical footprint dimensions. Physical dimensions vary slightly: 7440320056 measures 3.20mm × 2.50mm × 2.30mm (height), while TDK parts measure 3.20mm × 2.50mm × 2.40mm (height). These dimensional variations are within standard PCB design tolerances and do not affect assembly compatibility.

Q: Which substitute should be selected for new designs?

A: For new designs requiring 250 mA or higher current capability, select 7440320056 (Würth Elektronik). For designs with maximum current below 200 mA, either TDK part is acceptable. If automotive qualification is required, select NLV32T-5R6J-EFD (AEC-Q200 rated). For high-volume production, verify packaging availability with your supplier.
