Engineering Selection Recommendations

AISC-1210HS-6R8K-T2 (Abracon LLC) - Direct Substitute

The AISC-1210HS-6R8K-T2 is the primary recommended substitute for the 1210HS-682EKFS. This part maintains identical inductance (6.8 µH), package (1210), core type (ferrite drum core, unshielded), and operating temperature range (-40°C to 85°C). The Abracon part exceeds the current rating requirement with 480 mA capability and features lower DC resistance (1.1Ohm Max versus 1.5Ohm), providing improved performance characteristics. The part is active in production with 3218 units in stock. ROHS3 compliance and MSL 1 rating match the original specification. The reduced height (0.051" versus 0.094") and smaller footprint (3.20mm x 2.50mm versus 3.50mm x 2.80mm) may require PCB layout verification for mechanical clearance.

NLV32T-6R8J-EF (TDK Corporation) - Similar Substitute

The NLV32T-6R8J-EF is a similar substitute suitable for applications where the 1210HS-682EKFS current rating of 240 mA is not fully utilized. This TDK part maintains identical inductance (6.8 µH), package (1210), core type, and mounting type. The part features tighter inductance tolerance (±5% versus ±10%) and extended operating temperature range (-40°C to 105°C). However, the current rating is limited to 180 mA, which is below the original 240 mA specification. DC resistance is 1.8Ohm Max, exceeding the original 1.5Ohm specification. The part is active in production with 4140 units in stock and carries ROHS3 compliance. Physical dimensions match the Abracon substitute (3.20mm x 2.50mm footprint, 2.40mm height).

NLV32T-6R8J-EFD (TDK Corporation) - Similar Substitute with Automotive Rating

The NLV32T-6R8J-EFD is functionally identical to the NLV32T-6R8J-EF with the addition of AEC-Q200 automotive qualification. This part is suitable for applications requiring automotive-grade components. Current rating remains limited to 180 mA, and DC resistance is 1.8Ohm Max. The part is active in production with 980 units in stock. All other electrical and mechanical parameters match the NLV32T-6R8J-EF variant.

Selection Guidance:

For applications requiring the full 240 mA current rating and 1.5Ohm DC resistance specification, the AISC-1210HS-6R8K-T2 is the appropriate choice. For current-limited applications below 180 mA, either TDK variant is acceptable. The NLV32T-6R8J-EFD should be selected when automotive qualification (AEC-Q200) is a design requirement.

Frequently Asked Questions (FAQ)

Q: Can the AISC-1210HS-6R8K-T2 be used as a direct replacement for the 1210HS-682EKFS?

A: Yes. The AISC-1210HS-6R8K-T2 meets all core substitution criteria: identical 6.8 µH inductance, 1210 package, ferrite drum core construction, surface mount configuration, and operating temperature range. The Abracon part exceeds the current rating and provides lower DC resistance, making it electrically compatible. PCB layout verification is required due to reduced component height (0.051" versus 0.094").

Q: Why do the TDK parts (NLV32T-6R8J-EF and NLV32T-6R8J-EFD) show a lower current rating of 180 mA?

A: The TDK parts are rated for 180 mA continuous current, which is below the original 240 mA specification. These parts are suitable only for applications where the actual circuit current does not exceed 180 mA. If the design requires the full 240 mA capability, the AISC-1210HS-6R8K-T2 must be used.

Q: What is the difference between NLV32T-6R8J-EF and NLV32T-6R8J-EFD?

A: Both parts are electrically and mechanically identical with matching inductance, current rating, DC resistance, and physical dimensions. The NLV32T-6R8J-EFD includes AEC-Q200 automotive qualification, making it suitable for automotive applications. The NLV32T-6R8J-EF is the standard industrial variant.

Q: Are there any PCB layout considerations when substituting these parts?

A: Yes. The AISC-1210HS-6R8K-T2 has a reduced seated height of 0.051" (1.30mm) compared to the original 0.094" (2.40mm). Verify that the PCB pad layout and surrounding component placement accommodate this height difference. The Abracon and TDK parts also have slightly smaller footprints (3.20mm x 2.50mm versus 3.50mm x 2.80mm), which may affect pad alignment on existing PCB designs.

Q: Do all substitute parts maintain RoHS3 compliance?

A: Yes. All three substitute parts (AISC-1210HS-6R8K-T2, NLV32T-6R8J-EF, and NLV32T-6R8J-EFD) are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original part specification.

Q: What is the inductance tolerance difference between the original and substitute parts?

A: The original 1210HS-682EKFS has ±10% inductance tolerance. The TDK parts (NLV32T-6R8J-EF and NLV32T-6R8J-EFD) offer tighter ±5% tolerance. The Abracon AISC-1210HS-6R8K-T2 maintains ±10% tolerance. Tighter tolerance may benefit circuit performance but is not required for functional substitution.

Q: Can the substitute parts operate at temperatures above 85°C?

A: The AISC-1210HS-6R8K-T2 maintains the original operating range of -40°C to 85°C. The TDK parts (NLV32T-6R8J-EF and NLV32T-6R8J-EFD) extend the upper temperature limit to 105°C, providing additional thermal margin for high-temperature applications. If operation above 85°C is required, the TDK variants are suitable provided the 180 mA current rating is acceptable.

Q: What is the impact of DC resistance differences on circuit performance?

A: The original part specifies 1.5Ohm DC resistance. The AISC-1210HS-6R8K-T2 provides lower resistance at 1.1Ohm Max, reducing power dissipation and heat generation. The TDK parts specify 1.8Ohm Max, which increases power dissipation. For applications sensitive to inductor losses, the Abracon part offers improved efficiency. For applications with relaxed loss requirements, the TDK parts remain acceptable.
