DP83640TVV IEEE 1588 Transceiver Equivalent & Substitute Parts

Part Overview

The DP83640TVV is a Texas Instruments IEEE 1588 Transceiver IC in 48-LQFP surface mount packaging. This component is classified as Last Time Buy, indicating discontinued production with limited remaining inventory. The DP83640TVV serves as a precision timing interface for IEEE 1588 protocol applications requiring synchronization capabilities in networked systems. Substitute parts are necessary due to product status transition and to ensure long-term supply chain continuity for new designs or production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DP83640TVV is determined by strict equivalence across the following parameters:

• Base product number (DP83640 series)
• Protocol specification (IEEE 1588)
• Package type (48-LQFP with 7x7mm dimensions)
• Supply voltage range (3V ~ 3.6V)
• Surface mount mounting type
• RoHS3 compliance
• MSL rating (3, 168 Hours)
• REACH unaffected status

All substitute parts listed maintain identical electrical and mechanical specifications. Packaging format differences (Tray versus Cut Tape & Digi-Reel) do not affect functional compatibility and are determined by procurement and logistics requirements only.

Parameter Comparison

Engineering Selection Recommendations

The DP83640TVV is in Last Time Buy status, making it unsuitable for new production designs. Both DP83640TVV/NOPB and DP83640TVVX/NOPB are Active status alternatives with identical electrical and mechanical specifications.

Selection between active substitutes is based on packaging requirements:

• DP83640TVV/NOPB: Tray packaging for bulk procurement and automated assembly operations
• DP83640TVVX/NOPB: Cut Tape and Digi-Reel packaging for component tape feeders and pick-and-place equipment

Both alternatives maintain full compliance with ROHS3 and REACH requirements. Inventory availability should be evaluated against production timelines, as both parts maintain substantial stock levels (18,824 and 19,450 units respectively).

Frequently Asked Questions (FAQ)

Q: Can DP83640TVV/NOPB directly replace DP83640TVV in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The /NOPB suffix indicates lead-free plating compliance. Functional compatibility is complete across all IEEE 1588 protocol operations and supply voltage specifications.

Q: What is the difference between DP83640TVV/NOPB and DP83640TVVX/NOPB?

A: The parts are functionally equivalent. The primary difference is packaging format: DP83640TVV/NOPB uses Tray packaging, while DP83640TVVX/NOPB uses Cut Tape and Digi-Reel packaging. Selection depends on assembly process requirements and component handling systems.

Q: Are all three parts suitable for new product designs?

A: Only DP83640TVV/NOPB and DP83640TVVX/NOPB are recommended for new designs, as both maintain Active product status. DP83640TVV is Last Time Buy and should not be selected for new production.

Q: Do packaging differences affect PCB layout or soldering requirements?

A: No. All three parts use identical 48-LQFP (7x7mm) packages. PCB footprints, reflow profiles, and thermal management requirements are identical regardless of packaging format.

Q: Are moisture sensitivity precautions identical across all three parts?

A: Yes. All parts carry MSL rating 3 (168 Hours), requiring identical moisture control procedures during storage, handling, and assembly.
