Engineering Selection Recommendations

Primary Selection: TYS4018101M-10

The TYS4018101M-10 is the recommended choice for new circuit designs. This component maintains Active product status, indicating ongoing manufacturer support, continued availability, and compliance with current industry standards. The part is ROHS3 compliant and carries unlimited moisture sensitivity rating, suitable for standard manufacturing and storage environments.

Substitute Selection: NRS4018T101MDGJV

The NRS4018T101MDGJV from Taiyo Yuden serves as a functional equivalent when the primary part is unavailable. This substitute meets all electrical specifications with performance margins in current rating (280 mA vs. 250 mA requirement) and saturation current (420 mA vs. 400 mA requirement). The substitute features a lower seated height (1.80 mm vs. 2.00 mm), which may provide layout advantages in space-constrained applications.

However, the NRS4018T101MDGJV carries "Not For New Designs" status, indicating the manufacturer has discontinued active development. This designation restricts its use to legacy system maintenance, repair operations, or temporary supply solutions. For production designs with extended lifecycle requirements, the TYS4018101M-10 remains the appropriate selection.

Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings, ensuring compatibility with standard PCB assembly processes and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can NRS4018T101MDGJV be used as a direct replacement for TYS4018101M-10 in existing designs?

A: Yes. The substitute part meets all electrical parameters within specification and maintains identical package footprint (4.00mm x 4.00mm). The lower seated height (1.80mm vs. 2.00mm) presents no compatibility issues for standard PCB layouts. Both parts are surface mount, shielded inductors with matching inductance, tolerance, and operating temperature ranges.

Q: What is the significance of the "Not For New Designs" status on the substitute part?

A: This designation indicates that Taiyo Yuden has discontinued active development and support for the NRS4018T101MDGJV. While the part remains functionally equivalent and available in inventory, it should not be selected for new product designs with extended production lifecycles. Use this substitute only for legacy system support or temporary supply situations.

Q: Are there differences in DC resistance between the main part and substitute?

A: The DC resistance values are effectively equivalent. The main part specifies 1.75Ohm maximum, while the substitute specifies 1.74Ohm maximum. Both values fall within acceptable operating parameters for 100 µH inductor applications at 250 mA current levels.

Q: Does the lower height of the substitute part affect circuit performance?

A: No. The 0.20mm height reduction (from 2.00mm to 1.80mm) is a mechanical characteristic that does not alter electrical performance. Both parts maintain identical inductance, DC resistance, saturation current, and self-resonant frequency specifications. The lower profile may provide layout advantages in height-constrained applications.

Q: What compliance certifications apply to both parts?

A: Both the TYS4018101M-10 and NRS4018T101MDGJV are ROHS3 compliant, REACH unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). Both parts meet EAR99 export classification and 8504.50.4000 HTSUS tariff code requirements.

Q: Can these parts be used interchangeably in high-frequency applications?

A: Yes. Both parts specify identical self-resonant frequency of 6.5 MHz and are tested at 100 kHz inductance frequency. The shielded construction of both components provides electromagnetic isolation suitable for RF and high-frequency circuit applications.

Q: What inventory considerations should guide part selection?

A: The main part TYS4018101M-10 has 1903 units in stock with Active status, ensuring continued availability. The substitute NRS4018T101MDGJV has 5589 units available but carries "Not For New Designs" status, indicating limited future supply commitment. For production designs, prioritize the main part to ensure long-term supply security.
