FFF CompatibilityUses a 32-QFN package compared to the 80-LQFP, meaning pin connections and layout must be redesigned.Physically smaller 5x5mm footprint with a different pin pitch and mounting style.Fully supports standard IEEE 802.3 10BASE-T and 100BASE-TX MII transceiving.Different package (48-LQFP vs 80-LQFP) and pin layout requiring a complete PCB land pattern redesign.Smaller package outline (7x7mm vs 12x12mm) and reduced pin count (48 pins vs 80 pins).Matches the 10/100 Mbps Ethernet transceiver functionality, MII interface, registers, and electrical ratings.
AI Summary

DP83846AVHG/NOPB by Texas Instruments: Transceiver Ethernet 80-LQFP (12x12).

An excellent cross-manufacturer alternative from Microchip's robust KSZ series. It maintains the required MII interface for direct MAC communication and provides stable Ethernet link performance.

  • Provides a reliable second-source solution from an alternate manufacturer (Microchip)
  • Supports a full MII interface for drop-in communication compatibility with the MAC controller
  • Industrial temperature capability (-40°C to 85°C)
  • Requires PCB layout redesign and update to software drivers due to vendor-specific register map differences

This is the most logical upgrade path for obsolete DP83846A designs, featuring detailed migration support directly from Texas Instruments. It offers a highly reliable 10/100 Mbps Ethernet transceiver in a much smaller footprint.

  • Official migration path documented by Texas Instruments (AN-1499 / SNOA473)
  • Same MII interface and IEEE 802.3 compliance for 10/100 Base-TX/T operation
  • Widely used, highly robust, and actively in production
  • Requires complete redesign of the PCB land pattern and routing
  • Some minor register differences during software initialization

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
