The Realtek RTL8139D(L) is a highly integrated and cost-effective single-chip Fast Ethernet controller. Providing a highly flexible multi-function mode (Realtek patent pending), the new chip is able to support a versatile combination of applications. Furthermore, the RTL8139D(L) is equipped with a PCI and Boot ROM share interface (Realtek patent pending) for both EPROM and Flash Memory to provide maximum network security and ease of management.
The RTL8139D(L) offers an ACPI (Advanced Configuration Power Interface) management function to provide efficient power management for advanced operating systems with OSPM (Operating System Directed Power Management). A remote wake-up function is also provided by support to Magic Packet, Link Change, and Wake-up Frame to increase cost-efficiency in network maintenance and management. In addition, the RTL8139D(L) supports analog Auto Power-down and provides an auxiliary power auto-detect function to further save power.
YG GROUP (YUGUANG INTERNATIONAL(HK)CO.,LTD) supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
RTL8139D(L) is an authentic electronic component manufactured by Realtek, categorized under Communication & Networking ICs. It is supplied in the standard manufacturer-specified package footprint, providing industry-standard mechanical dimensions and terminal configurations for board-level assembly. Full pinout configurations, physical footprint drawings, and rated operating tolerances are documented in the official RTL8139D(L) datasheet above.
Electronic component spot-market pricing for RTL8139D(L) fluctuates based on real-time global availability, production date codes, minimum order quantities (MOQ), and packaging formats (e.g., Reel, Tube, Tray). Using an RFQ ensures you receive accurate, real-time volume pricing tied to verified, traceable inventory rather than stale catalog estimates.
Lead times for RTL8139D(L) depend on whether stock is dispatched from our central hub or regional franchise partners. Ready-to-ship inventory typically leaves the warehouse within 1–3 business days following quality inspection, while factory-direct or back-ordered allocations are confirmed with an estimated ship date upon RFQ reply.
