VLS5045EX-101M Equivalent & Substitute Parts

Part Overview

The VLS5045EX-101M is a 100 µH shielded drum core wirewound inductor manufactured by TDK Corporation, rated for 700 mA continuous current with a maximum DC resistance of 754 mOhm. This surface mount component operates across the temperature range of -40°C to 105°C and is classified as Active product status. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this inductance value and current rating category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLS5045EX-101M is determined by the following critical parameters:

• Inductance value of 100 µH at 100 kHz test frequency
• Tolerance of ±20%
• Ferrite core material construction
• Surface mount configuration with 5.00mm x 5.00mm footprint
• Current rating capability of 650 mA minimum (acceptable for 700 mA rated applications with thermal margin consideration)
• DC resistance within acceptable operating limits
• Operating temperature range compatibility
• RoHS3 compliance and REACH unaffected status

The SDCH1V5040-101M-R from Eaton - Electronics Division meets these substitution criteria with equivalent inductance, matching footprint dimensions, compatible temperature range, and identical compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both components maintain Active product status and satisfy ROHS3 compliance and REACH unaffected requirements. The VLS5045EX-101M remains the primary specification when maximum current rating of 700 mA and full shielding are required. The SDCH1V5040-101M-R from Eaton serves as a functional substitute in applications where the 650 mA current rating provides adequate margin above peak operating current, semi-shielded construction is acceptable for EMI performance, and the extended operating temperature range to 125°C offers thermal design flexibility. The lower DC resistance of the Eaton part (633 mOhm vs. 754 mOhm) reduces power dissipation. Verify PCB layout clearance due to the 0.40mm height difference between components.

Frequently Asked Questions (FAQ)

Q: Can the SDCH1V5040-101M-R replace the VLS5045EX-101M in all applications?

A: The Eaton part is suitable for applications where the 650 mA current rating exceeds the required operating current with adequate thermal margin, semi-shielded construction meets EMI requirements, and the lower profile (4.10mm vs. 4.50mm) does not conflict with PCB assembly constraints.

Q: What is the difference between shielded and semi-shielded construction?

A: The VLS5045EX-101M provides full shielding for maximum EMI containment. The SDCH1V5040-101M-R uses semi-shielded construction, which reduces but does not eliminate electromagnetic field confinement. Applications sensitive to radiated or conducted EMI should retain the fully shielded VLS5045EX-101M.

Q: Are the footprints identical?

A: Both components share the same 5.00mm x 5.00mm surface mount footprint. The Eaton part is 0.40mm shorter in seated height (4.10mm vs. 4.50mm), which may affect clearance in densely populated assemblies.

Q: Do both parts meet compliance requirements?

A: Both the VLS5045EX-101M and SDCH1V5040-101M-R are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level).

Q: What is the impact of the lower DC resistance in the Eaton part?

A: The SDCH1V5040-101M-R exhibits 633 mOhm maximum DC resistance compared to 754 mOhm for the TDK part. Lower resistance reduces I²R power dissipation and heat generation, which is favorable for thermal performance in current-limited applications.
