VLS201610ET-R68N Equivalent & Substitute Parts

Part Overview

The VLS201610ET-R68N is a 680 nH shielded drum core wirewound inductor manufactured by TDK Corporation, rated for 1.65 A maximum current with 86 mOhm DC resistance. This component is classified as "Not For New Designs," indicating it has been superseded in TDK's product portfolio. Finding equivalent or substitute parts is necessary for applications requiring continued support, inventory replenishment, or design transitions to active product lines while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the VLS201610ET-R68N is determined by the following critical parameters:

Inductance value must remain 680 nH to maintain circuit performance and frequency response characteristics. The shielded drum core construction and ferrite material must be preserved to ensure electromagnetic compatibility and noise suppression properties. Surface mount packaging with identical footprint dimensions (2.00mm x 1.60mm) is required for PCB compatibility without layout modifications. Operating temperature range of -40°C to 105°C must be maintained or exceeded. RoHS3 compliance and REACH unaffected status must be retained for regulatory alignment.

Current rating and DC resistance may vary within acceptable engineering margins, provided the substitute part meets or exceeds the original specifications or is suitable for the specific application circuit requirements. Tolerance and saturation current specifications may differ between substitute parts while maintaining functional equivalence.

Engineering Selection Recommendations

The VLS201610CX-R68M-1 is the manufacturer-recommended substitute for the VLS201610ET-R68N. Both parts maintain identical inductance values, shielding characteristics, core materials, and footprint dimensions. The substitute part is classified as Active, providing long-term availability and supply chain stability compared to the obsolete status of the original part.

The VLS201610CX-R68M-1 offers improved electrical performance with higher current rating (2.19 A versus 1.65 A), lower DC resistance (76 mOhm versus 86 mOhm), and tighter inductance tolerance (±20% versus ±30%). These enhancements make it suitable for applications where the original part was specified, with additional design margin for current handling and reduced power dissipation.

Height difference of 0.05mm (1.00mm versus 0.95mm) is negligible for standard PCB assembly processes and does not impact component placement or clearance in typical circuit board designs. Both parts maintain identical compliance certifications and operating temperature specifications.

Frequently Asked Questions (FAQ)

Q: Can the VLS201610CX-R68M-1 be used as a direct replacement for the VLS201610ET-R68N?

A: Yes. Both parts share identical inductance (680 nH), shielding, core material, footprint dimensions (2.00mm x 1.60mm), and operating temperature range. The substitute part is electrically and mechanically compatible for direct PCB substitution without layout modifications.

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

A: The substitute part offers higher current rating (2.19 A versus 1.65 A), lower DC resistance (76 mOhm versus 86 mOhm), and tighter tolerance (±20% versus ±30%). Height increases by 0.05mm. The substitute is Active status versus Not For New Designs.

Q: Does the height difference of 0.05mm affect PCB assembly?

A: No. The 0.05mm height difference (0.95mm to 1.00mm) is within standard PCB assembly tolerances and does not impact component placement, solder reflow, or clearance requirements in typical applications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the VLS201610ET-R68N and VLS201610CX-R68M-1 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: Why is the original part marked "Not For New Designs"?

A: This designation indicates the part has been superseded by newer alternatives in TDK's product portfolio. The VLS201610CX-R68M-1 represents the active equivalent with improved specifications and guaranteed long-term availability.

Q: Can I use the substitute part in existing designs without circuit modifications?

A: Yes. The substitute part maintains all critical electrical parameters (inductance, shielding, core material) and mechanical compatibility (footprint, mounting type). No circuit modifications are required for direct substitution.
