Parameter Comparison

Engineering Selection Recommendations

744032004 (Würth Elektronik WE-LQ Series)

The 744032004 is an active product with current rating of 490 mA, exceeding the 270 mA requirement of the original part. DC resistance of 280 mOhm is significantly lower than the 1.2 Ohm specification. Operating temperature range extends to 125°C, providing enhanced thermal margin. This part is suitable for direct substitution in applications where the lower DC resistance and higher current capacity do not create design conflicts.

BRL3225T4R7M (Taiyo Yuden BR, L Type Series)

The BRL3225T4R7M carries a "Not For New Designs" status but remains available in inventory. Current rating of 1 A substantially exceeds the 270 mA requirement. DC resistance of 216 mOhm is lower than the original specification. Operating temperature range of -40°C to 105°C covers the original operating window. This part is suitable for legacy system support and maintenance applications where new design constraints do not apply.

NLCV32T-4R7M-EF (TDK NLCV-EF Series, Tape & Reel)

The NLCV32T-4R7M-EF is an active product with current rating of 620 mA, exceeding the 270 mA requirement. DC resistance of 260 mOhm is lower than the 1.2 Ohm specification. Operating temperature range of -40°C to 105°C provides adequate thermal coverage. This part is suitable for direct substitution with standard tape and reel packaging.

NLCV32T-4R7M-EFD (TDK NLCV-EFD Series, Cut Tape)

The NLCV32T-4R7M-EFD is an active product with identical electrical specifications to the NLCV32T-4R7M-EF variant. Current rating of 620 mA and DC resistance of 260 mOhm meet substitution requirements. This part includes AEC-Q200 automotive qualification rating. Packaging is supplied in cut tape format. This part is suitable for applications requiring automotive-grade components or cut tape delivery format.

NLCV32T-4R7M-EFR (TDK NLCV-EF Series, Cut Tape & Digi-Reel)

The NLCV32T-4R7M-EFR is an active product with current rating of 900 mA and DC resistance of 240 mOhm, both exceeding the original part specifications. Operating temperature range of -40°C to 105°C provides adequate thermal coverage. Packaging is supplied in cut tape and Digi-Reel format. This part is suitable for applications requiring the lowest DC resistance profile or alternative packaging formats.

Frequently Asked Questions (FAQ)

Q: Can the 1210HS-472EMFS be directly replaced with any of the listed substitute parts?

A: Yes. All listed substitute parts maintain the same 4.7 µH inductance value, ±20% tolerance, 1210 (3225 Metric) package footprint, and surface mount configuration. All substitute parts meet or exceed the 270 mA current rating and provide DC resistance equal to or lower than the original 1.2 Ohm specification. Mechanical and electrical compatibility is confirmed.

Q: What is the primary difference between the substitute parts?

A: The substitute parts differ in current rating, DC resistance, operating temperature range, product status, and packaging format. The 744032004 offers the widest operating temperature range (-40°C to 125°C). The BRL3225T4R7M carries a "Not For New Designs" status. The TDK variants (NLCV32T-4R7M-EF, NLCV32T-4R7M-EFD, NLCV32T-4R7M-EFR) are all active products with varying current ratings and packaging options.

Q: Does lower DC resistance affect circuit performance?

A: Lower DC resistance in substitute parts reduces resistive losses and heat generation compared to the original 1.2 Ohm specification. This is generally beneficial for circuit efficiency. However, circuit designers must verify that the lower resistance does not alter intended circuit behavior, particularly in applications where the original DCR value was intentionally specified for damping or impedance matching purposes.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited) rating, matching the environmental and regulatory compliance profile of the original 1210HS-472EMFS.

Q: What is the difference between the TDK NLCV32T-4R7M variants?

A: The NLCV32T-4R7M-EF is supplied in tape and reel format with 620 mA current rating. The NLCV32T-4R7M-EFD is supplied in cut tape format with identical electrical specifications and includes AEC-Q200 automotive qualification. The NLCV32T-4R7M-EFR is supplied in cut tape and Digi-Reel format with 900 mA current rating and 240 mOhm DC resistance.

Q: Which substitute part is recommended for new designs?

A: For new designs, select from parts with "Active" product status: 744032004 (Würth), NLCV32T-4R7M-EF (TDK), NLCV32T-4R7M-EFD (TDK), or NLCV32T-4R7M-EFR (TDK). The BRL3225T4R7M carries "Not For New Designs" status and is suitable only for legacy system support and maintenance applications.

Q: Can substitute parts be used in high-temperature applications?

A: The original 1210HS-472EMFS operates to 85°C. All substitute parts extend the operating range to 105°C or higher, providing enhanced thermal margin. The 744032004 extends to 125°C, offering the widest temperature coverage. Verify that the selected substitute part's operating temperature range meets the specific application requirements.

Q: What packaging formats are available for the substitute parts?

A: The 744032004 is supplied in tape and reel format. The BRL3225T4R7M is supplied in tape and reel format. The NLCV32T-4R7M-EF is supplied in tape and reel format. The NLCV32T-4R7M-EFD is supplied in cut tape format. The NLCV32T-4R7M-EFR is supplied in cut tape and Digi-Reel format. Select the packaging format that matches assembly line requirements.
