HR911105A Application Guide


I’ll research the HR911105A datasheet and primary-source integration guidance, then create a cited Application & Usage Guide in the project files, explicitly marking any unverified specifications or replacement compatibility.
I verified the current HanRun A/6 ratings, LED characteristics, and two functional alternatives. Some pin assignments remain unresolved in the retrieved schematic evidence, so I’ll flag those explicitly rather than publish a potentially unsafe wiring recommendation.

HR911105A Application and Usage Guide
The HanRun HR911105A is a single-port, through-hole RJ45 connector with integrated magnetics and green/yellow LEDs for 10/100BASE-T Ethernet interfaces (manufacturer product page). Its common use is the cable interface of an embedded Ethernet PHY or Ethernet controller; it is explicitly a non-PoE component, not a PHY or a Gigabit Ethernet connector (manufacturer product page).
Evidence scope: Prepared 7 October 2026 using HanRun revision A/6. Verified facts have inline evidence citations; engineering recommendations and calculations are identified separately. The retrieved schematic evidence did not resolve every pin or LED polarity, and PHY application...
Created the HR911105A Application & Usage Guide in project files, covering all seven requested sections with citations, LED resistor calculations, and sourcing guidance.
Open items: Several pin assignments, LED polarities, and PHY-specific application details remain explicitly unverified; neither alternative is claimed as a drop-in replacement. Before using the guide for production, verify the original schematic drawing and the chosen PHY’s reference circuit.
