VLP6045LT-101M Equivalent & Substitute Parts

Part Overview

The VLP6045LT-101M is a 100 µH shielded drum core wirewound inductor manufactured by TDK Corporation, rated for 800 mA continuous current with a maximum DC resistance of 663 mOhm. This surface mount component operates across the temperature range of -40°C to 105°C and is designed for applications requiring compact, shielded inductive filtering.

The VLP6045LT-101M has reached obsolete product status. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications. Two qualified substitute options are available that maintain the core electrical specifications while offering improved availability and enhanced performance characteristics.

Engineering Selection Recommendations

VLS6045EX-101M (TDK Corporation - Recommended Primary Substitute)

The VLS6045EX-101M is the manufacturer-recommended substitute from TDK Corporation. This part maintains active product status with high inventory availability (48,320 pcs). It provides improved electrical performance with 900 mA current rating and 1.1 A saturation current, exceeding the original specification. DC resistance is reduced to 470 mOhm, resulting in lower power dissipation. The component is ROHS3 compliant and maintains identical operating temperature range and moisture sensitivity classification. Physical dimensions are slightly smaller (6.00mm x 6.00mm), which may require PCB layout verification for space-constrained applications.

DR73-101-R (Eaton - Electronics Division - Secondary Substitute)

The DR73-101-R provides an alternative from Eaton - Electronics Division with exceptional inventory availability (565,900 pcs). This part maintains active product status and is ROHS3 compliant. The extended operating temperature range (-40°C to 125°C) provides additional thermal margin. DC resistance of 527 mOhm is lower than the original specification. Current rating of 730 mA is below the original 800 mA specification, and saturation current of 790 mA is below the original 900 mA specification. Physical dimensions are larger (7.60mm x 7.60mm with 4.65mm height), requiring PCB layout compatibility verification. This substitute is suitable for applications where current requirements do not exceed 730 mA continuous operation.

Frequently Asked Questions (FAQ)

Q: Can VLS6045EX-101M directly replace VLP6045LT-101M in all applications?

A: The VLS6045EX-101M meets or exceeds all primary electrical specifications of the VLP6045LT-101M. The smaller physical footprint (6.00mm vs 6.80mm) requires verification that PCB layout accommodates the reduced dimensions. The improved current rating and lower DC resistance make this a functionally superior substitute for applications operating at or below 800 mA.

Q: What are the limitations of using DR73-101-R as a substitute?

A: The DR73-101-R has a continuous current rating of 730 mA, which is 70 mA below the original VLP6045LT-101M specification of 800 mA. Saturation current is 790 mA versus the original 900 mA. This substitute is appropriate only for applications where sustained current does not exceed 730 mA. The larger physical dimensions (7.60mm x 7.60mm) must be verified against PCB layout constraints.

Q: Are both substitute parts compatible with the original PCB design?

A: Physical compatibility requires verification. The VLS6045EX-101M has a smaller footprint (6.00mm x 6.00mm) than the original (6.80mm x 6.80mm), while the DR73-101-R is larger (7.60mm x 7.60mm). Both maintain the same 4.50mm or lower height. PCB pad spacing and component placement must be reviewed to confirm mechanical fit.

Q: What compliance certifications apply to the substitute parts?

A: Both VLS6045EX-101M and DR73-101-R are ROHS3 compliant and REACH unaffected. Both maintain MSL 1 (Unlimited) moisture sensitivity classification, matching the original part. ECCN and HTSUS classifications are provided in the detailed specifications.

Q: Which substitute should be selected for new designs?

A: For new designs, VLS6045EX-101M is the recommended choice as the manufacturer-recommended substitute from TDK Corporation with superior electrical performance and active product status. DR73-101-R is suitable as an alternative when current requirements are confirmed below 730 mA and physical dimensions are compatible with the PCB layout.
