Engineering Selection Recommendations

The MLZ1608DR47DT000 is the designated substitute for the obsolete GLFR1608TR47M-LR. Both components are manufactured by TDK Corporation and maintain identical inductance values, tolerances, package dimensions, and shielding characteristics. The substitute part carries active product status, ensuring continued availability and manufacturing support.

The MLZ1608DR47DT000 operates across an extended temperature range (-55°C to 125°C) compared to the original part (-40°C to 105°C), providing broader thermal operating capability. Both parts meet ROHS3 compliance and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Design considerations for substitution include the difference in current ratings and DC resistance. The original GLFR1608TR47M-LR is rated for 1.1 A continuous current with 50 mOhm DCR, while the MLZ1608DR47DT000 is rated for 500 mA continuous current with 420 mOhm DCR. Circuit designs operating at or near the 1.1 A rating of the original part require evaluation to confirm compatibility with the 500 mA rating of the substitute.

Frequently Asked Questions (FAQ)

Q: Can the MLZ1608DR47DT000 directly replace the GLFR1608TR47M-LR in existing designs?

A: The MLZ1608DR47DT000 maintains identical inductance value, tolerance, package footprint, and shielding as the GLFR1608TR47M-LR. Circuit designs operating below 500 mA can use this substitute without modification. Designs requiring the full 1.1 A current rating of the original part require current capacity evaluation.

Q: What are the key differences between these two parts?

A: The primary differences are current rating (1.1 A vs. 500 mA), DC resistance (50 mOhm vs. 420 mOhm), and product status (obsolete vs. active). The substitute part offers an extended operating temperature range and higher saturation current (400 mA vs. 300 mA).

Q: Are both parts compatible with the same PCB footprint?

A: Yes. Both the GLFR1608TR47M-LR and MLZ1608DR47DT000 use the 0603 (1608 Metric) package with identical physical dimensions (0.063" L x 0.031" W). The substitute part has a slightly lower seated height (0.037" vs. 0.039"), which does not affect PCB compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings. Both are assigned ECCN EAR99 and HTSUS 8504.50.4000 classifications.

Q: What is the saturation current difference, and does it matter?

A: The GLFR1608TR47M-LR has a saturation current of 300 mA, while the MLZ1608DR47DT000 has 400 mA. The substitute part maintains inductance stability at higher current levels before saturation occurs.
