27T682C Equivalent & Substitute Parts

Part Overview

The 27T682C is a 6.8 µH unshielded wirewound surface mount inductor manufactured by Murata Power Solutions Inc., rated for 850 mA continuous current with a maximum DC resistance of 320mOhm. This component is classified as Active product status and is RoHS3 compliant. Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design requirements necessitate alternative form factors or electrical characteristics within acceptable tolerance ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 27T682C is determined by the following critical parameters:

• Inductance Value: Must be 6.8 µH with ±20% tolerance
• Current Rating: Minimum 800 mA (substitute may have lower rating if application permits)
• DC Resistance: Maximum 300mOhm to 320mOhm
• Shielding Configuration: Unshielded only
• Mounting Type: Surface Mount required
• Package Classification: Nonstandard form factor
• Compliance: RoHS3 and REACH Unaffected status required

The VLP5610T-6R8MR80 from TDK Corporation meets these substitution criteria with matching inductance, compatible current rating (800 mA), lower DC resistance (300mOhm), identical shielding, and equivalent compliance certifications.

Engineering Selection Recommendations

The 27T682C remains the preferred selection as an Active product with current manufacturer support and RoHS3 compliance certification. The VLP5610T-6R8MR80 serves as a functional equivalent for applications where the 27T682C becomes unavailable, provided that the 800 mA current rating and 300mOhm DC resistance are acceptable within circuit design margins. The VLP5610T-6R8MR80 exhibits a smaller physical footprint and lower profile, which may provide layout advantages in space-constrained applications. However, the Obsolete product status of the VLP5610T-6R8MR80 indicates limited future availability and should be considered a temporary substitution strategy only.

Frequently Asked Questions (FAQ)

Q: Can the VLP5610T-6R8MR80 be used as a direct replacement for the 27T682C?

A: The VLP5610T-6R8MR80 is electrically compatible for applications operating at or below 800 mA. The lower current rating and reduced DC resistance are acceptable substitutions provided circuit design does not require the full 850 mA capability of the primary part. Physical dimensions differ slightly; PCB layout verification is required.

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

A: Both parts share identical inductance (6.8 µH), tolerance (±20%), shielding (unshielded), and mounting type (surface mount). The VLP5610T-6R8MR80 has a lower current rating (800 mA vs. 850 mA), lower DC resistance (300mOhm vs. 320mOhm), and a smaller physical footprint (5.60mm x 5.00mm vs. 6.45mm x 5.40mm).

Q: Are there compliance or regulatory concerns with substitution?

A: The 27T682C carries RoHS3 compliance certification. The VLP5610T-6R8MR80 maintains REACH Unaffected status matching the primary part. Verify RoHS3 compliance documentation for the substitute part before final design approval if regulatory compliance is a requirement.

Q: Why is the VLP5610T-6R8MR80 marked as Obsolete?

A: Obsolete status indicates the manufacturer (TDK) has discontinued active production and support. This part should be considered only when the 27T682C is unavailable and existing inventory of the substitute can be secured. Long-term design strategies should prioritize the Active 27T682C.

Q: Does the smaller size of the VLP5610T-6R8MR80 affect performance?

A: Physical size reduction does not alter the electrical performance of the inductor within the specified parameters. The 6.8 µH inductance, tolerance, and DC resistance remain functionally equivalent. PCB layout and thermal management considerations may differ due to the smaller footprint.
