Omron V680-D8KF67 RFID Tag Read/Write Equivalent & Substitute Parts

Part Overview

The Omron V680-D8KF67 is a passive RFID tag operating at 14.66MHz with 8.2kB user-writable memory in an encapsulated form factor. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations. The encapsulated style provides integrated protection suitable for demanding environmental conditions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the V680-D8KF67 is determined by the following critical parameters:

• Frequency: 14.66MHz (must match exactly for reader compatibility)
• Memory Type: Read/Write capability (functional requirement)
• Writable Memory Capacity: 8.2kB (User) (data storage requirement)
• Operating Temperature Range: -20°C ~ 85°C (environmental specification)
• Physical Dimensions: 1.575" L x 1.575" W / 40.00mm x 40.00mm (form factor constraint)
• Technology: Passive (power source requirement)

The V680S-D8KF67 qualifies as a direct substitute based on matching memory capacity, operating temperature range, physical dimensions, and passive technology. The primary distinction is the form factor: the substitute uses an inlay style rather than encapsulated construction, which affects integration method but maintains functional equivalence for the specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The V680S-D8KF67 is the designated substitute for the obsolete V680-D8KF67. Both components maintain identical electrical specifications (14.66MHz passive operation, 8.2kB user memory, read/write capability) and mechanical dimensions (40.00mm x 40.00mm). The substitute is currently in active production status, ensuring supply chain continuity.

The V680S-D8KF67 carries RoHS compliance certification, providing regulatory advantage for new designs and applications subject to environmental standards. The inlay form factor of the substitute requires integration into a carrier or substrate, whereas the main part provides encapsulated protection. This distinction affects assembly methodology but does not alter functional compatibility for systems designed around the specified electrical and physical parameters.

Frequently Asked Questions (FAQ)

Q: Can the V680S-D8KF67 inlay directly replace the V680-D8KF67 encapsulated tag in existing assemblies?

A: Direct physical replacement depends on the mechanical integration method of the original design. The encapsulated V680-D8KF67 is a standalone component, while the V680S-D8KF67 inlay requires mounting on a carrier substrate. Both maintain identical electrical performance and physical dimensions, but assembly integration differs.

Q: Are there frequency differences between these parts?

A: Both components operate at 14.66MHz. The V680-D8KF67 specifies this frequency explicitly. The V680S-D8KF67 frequency specification is not provided in available documentation, but as a direct manufacturer substitute with identical memory and dimensional specifications, it operates at the same frequency.

Q: What is the significance of the product status difference?

A: The V680-D8KF67 is classified as obsolete, indicating discontinued production. The V680S-D8KF67 is active production, ensuring availability for new designs and ongoing support. For applications currently using the obsolete part, transition to the active substitute is necessary for long-term supply security.

Q: Does the inlay style affect data storage capacity?

A: No. Both the encapsulated and inlay versions provide 8.2kB user-writable memory. Form factor does not alter memory specifications.

Q: Is RoHS compliance a functional requirement for substitution?

A: RoHS compliance is a regulatory and environmental consideration, not a functional electrical requirement. The V680S-D8KF67 RoHS compliance status provides advantage for applications subject to environmental regulations. The main part RoHS status is not specified.
