1. Competitor Product Overview (HanRun Electronics Company Limited)
HanRun (HanRun Electronics Company Limited) is a connector and magnetics manufacturer based in Zhongshan, Guangdong, China. The HR911130A is a 1×1 single-port Tab-Down RJ45 jack with integrated 100/1000Base-T magnetics and a green (left)/yellow (right) bi-color LED. It specifies OCL 350µH min, turn ratio 1CT:1CT, insertion loss ≤1.1dB, isolation 2250V DC, 750-cycle durability, ≤5 lbs mating force, operating 0 to +70°C and storage -40 to +85°C. The housing is PA66 (UL94V-0), the shield is 0.20mm nickel-plated brass, and the terminals are phosphor bronze (0.35mm, 30µin gold on the contact area). It is rated to meet or exceed IEEE 802.3ab for 1000Base-T.
2. VOOHU Replacement Overview (Suzhou VOOHU Electronic Technology Co., Ltd.)
The VOOHU SYT-320DNL, designed and manufactured by Suzhou VOOHU Electronic Technology Co., Ltd., is a Tab-Down single-port RJ45 jack with integrated magnetics for 10/100/1000Base-T Ethernet. It matches the HR911130A on OCL (350µH), turn ratio (1CT:1CT), isolation (2250V DC), body width (16.00mm), 750-cycle durability and storage temperature (-40 to +85°C), and improves on crosstalk (-40/-35/-30dB vs -35/-26/-24dB) and high-frequency insertion loss (≤1.0dB across the full 1–100MHz band), with the same green/yellow bi-color LED (green left, yellow right). Its operating temperature is extended to -40 to +85°C (industrial grade vs the competitor's commercial 0 to +70°C) and it is REACH & RoHS compliant, making it a wide-temperature drop-in alternative to the HR911130A.

Notes:
- All table parameters are taken strictly from the two datasheets (HanRun HR911130A / VOOHU SYT-320DNL); only items specified by both and matchable one-to-one are listed. Items missing on either side are not tabulated.
- Matching key items: OCL (both 350µH), turn ratio (both 1CT:1CT), isolation (both 2250V DC), durability (both 750 cycles), storage temperature (both -40 to +85°C) and body width (both 16.00mm).
- VOOHU advantages: operating temperature -40 to +85°C (industrial) vs 0 to +70°C (commercial); crosstalk (-40/-35/-30dB) better than -35/-26/-24dB; insertion loss ≤1.0dB across the full 1–100MHz band (better than -1.1dB at high frequency).
- Dielectric test conditions differ slightly: HanRun 2250V DC / 0.5mA / 60s; VOOHU 2250V DC / 1mA / 6s and additionally rated 1500V AC. Both are rated 2250V DC.
- Return loss and crosstalk use different frequency-band definitions; values are reproduced as-specified without conversion.
- CMR: HanRun specifies -40dB over 1–60MHz, VOOHU -30dB Min over the full 1–100MHz; both meet gigabit Ethernet requirements.
- Contact gold plating differs: HanRun 30µin gold / 50µin nickel, VOOHU 6µin gold; both use 0.35mm phosphor bronze terminals. LED forward voltage: HanRun 1.8/2.8V (Min/Max), VOOHU green 1.85–2.45V, yellow 1.7–2.2V.
- Items HanRun lists that VOOHU does not tabulate (e.g. unmating force 5 lbs Max, plug-to-jack retention 12 lbs Min) are omitted from the table.
- Pinout/footprint: both are single-port gigabit RJ45 magjacks with green (left)/yellow (right) bi-color LEDs; confirm full pin-to-pin/footprint compatibility against actual samples and the PCB layout before mass production.
4. Applications

5. FAQ
Q1: Can the VOOHU SYT-320DNL replace the HanRun HR911130A?
Both are single-port RJ45 magjacks (Tab-Down, green-left/yellow-right bi-color LED) and match on OCL (350µH), turn ratio (1CT:1CT), isolation (2250V DC), body width (16.00mm) and durability (750 cycles), so the VOOHU part is a pin-to-pin replacement candidate. Sample validation against the actual PCB layout is recommended before mass production.
Q2: What are the main differences?
The most notable difference is operating temperature — VOOHU is -40 to +85°C (industrial) vs 0 to +70°C (commercial); VOOHU also offers better crosstalk and high-frequency insertion loss.
Q3: Is it 1000Base-T / IEEE 802.3 compliant?
Yes, both are 100/1000Base-T magnetics modules with 2250V DC isolation, meeting IEEE 802.3 requirements.
