EST0645T151MDGA Equivalent & Substitute Parts

Part Overview

The EST0645T151MDGA is a 150 µH shielded drum core wirewound inductor manufactured by Taiyo Yuden, rated for 720 mA continuous current with 475 mOhm DC resistance. This component is classified as Not For New Designs, indicating it has been superseded in the manufacturer's product line. The part operates across the temperature range of -55°C to 150°C and meets AEC-Q200 automotive qualification standards.

Identification of equivalent substitute parts is necessary due to the product's discontinued status for new design implementations. Organizations requiring this inductance value and current rating must evaluate active alternatives that maintain electrical and mechanical compatibility within specified tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EST0645T151MDGA is determined by strict alignment of the following electrical and mechanical parameters:

Electrical Parameters (Critical):

• Inductance value of 150 µH within ±20% tolerance
• Continuous current rating of 720 mA or greater
• DC resistance of 475 mOhm
• Saturation current (Isat) of 500 mA or greater

Mechanical and Environmental Parameters (Important):

• Ferrite core material with shielding
• Surface mount wirewound construction
• Nonstandard package dimensions compatible with 6.30mm × 6.10mm footprint
• Operating temperature range of -55°C to 150°C
• AEC-Q200 automotive qualification
• RoHS3 compliance

Substitute parts must satisfy all critical electrical parameters and maintain compatibility across mechanical, thermal, and regulatory specifications. Dimensional variations within the nonstandard package classification are permissible provided the component remains surface-mountable within the specified footprint envelope.

Parameter Comparison

Engineering Selection Recommendations

The LAYPH06045DL151MGA serves as an active substitute for the discontinued EST0645T151MDGA. Both components are manufactured by Taiyo Yuden and maintain identical inductance, tolerance, DC resistance, and saturation current specifications. Both parts satisfy AEC-Q200 automotive qualification and RoHS3 compliance requirements.

The primary engineering consideration is the reduced continuous current rating of the LAYPH06045DL151MGA at 490 mA compared to the EST0645T151MDGA at 720 mA. This reduction must be evaluated against circuit requirements. If the application circuit operates at or below 490 mA continuous current, the substitute part provides full functional equivalence. If the circuit requires the full 720 mA rating, the substitute part is not suitable.

Dimensional compatibility is maintained across both parts. The LAYPH06045DL151MGA exhibits a maximum seated height of 4.80mm compared to 4.50mm for the main part, representing a 0.30mm increase. This dimensional difference must be verified against PCB layout and enclosure clearance constraints.

The LAYPH06045DL151MGA is classified as Active product status, ensuring continued availability and manufacturing support, whereas the EST0645T151MDGA is Not For New Designs. For new design implementations, the LAYPH06045DL151MGA is the appropriate selection provided current rating requirements do not exceed 490 mA.

Frequently Asked Questions (FAQ)

Q: Can the LAYPH06045DL151MGA directly replace the EST0645T151MDGA in all applications?

A: Direct replacement is possible only when the circuit operates at continuous currents of 490 mA or below. The EST0645T151MDGA is rated for 720 mA continuous current, while the LAYPH06045DL151MGA is rated for 490 mA. If the application requires the full 720 mA rating, the substitute part is not suitable.

Q: Are the inductance values identical between these parts?

A: Yes. Both parts provide 150 µH inductance with ±20% tolerance. The inductance value and tolerance are identical.

Q: What is the difference in DC resistance between these parts?

A: The DC resistance is identical at 475 mOhm for both the EST0645T151MDGA and LAYPH06045DL151MGA.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both parts carry AEC-Q200 automotive qualification ratings and operate across the identical temperature range of -55°C to 150°C.

Q: Are there dimensional differences that affect PCB layout?

A: The parts are dimensionally similar with minor variations. The LAYPH06045DL151MGA has a maximum seated height of 4.80mm compared to 4.50mm for the EST0645T151MDGA. The length and width dimensions are 6.30mm × 6.00mm for the substitute versus 6.30mm × 6.10mm for the main part. These differences are within typical PCB layout tolerances but must be verified against specific board design constraints.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the EST0645T151MDGA and LAYPH06045DL151MGA are RoHS3 compliant.

Q: What is the saturation current rating for both parts?

A: Both parts have an identical saturation current (Isat) rating of 500 mA.

Q: Why is the EST0645T151MDGA marked as Not For New Designs?

A: The EST0645T151MDGA has been superseded in the manufacturer's product line. Taiyo Yuden recommends using the LAYPH06045DL151MGA for new design implementations. Existing inventory of the EST0645T151MDGA remains available for legacy system support and maintenance applications.

Q: Is the LAYPH06045DL151MGA available in the same packaging format?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.
