RJ45 Integrated Magnetics Connector: VOOHU SYT511Q293AC1A8D057 as a Replacement for HanRun HR871190A
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 HR871190A is a 1×1 single-port Tab-Up RJ45 jack with integrated magnetics for 100/1000Base-TX NIC and gigabit Ethernet applications, containing four 1CT:1CT transformer pairs and a green/yellow bi-color LED, RoHS compliant. It specifies OCL 350µH, insertion loss ≤1.1dB, CMR -20dB, isolation 2250VDC and an operating range of 0 to +70°C.
2. VOOHU Replacement Overview (Suzhou VOOHU Electronic Technology Co., Ltd.)
The VOOHU SYT511Q293AC1A8D057, designed and manufactured by Suzhou VOOHU Electronic Technology Co., Ltd., is a Tab-Up single-port RJ45 jack with integrated magnetics for 1000Base-T gigabit Ethernet. It matches the HR871190A on OCL (350µH), turn ratio (1CT:1CT) and isolation (2250VDC), and improves on insertion loss (≤1.0dB vs 1.1dB) and CMR (-30dB vs -20dB), with the same green/yellow bi-color LED (green 11/12, yellow 13/14). Its operating temperature is extended to -40 to +85°C and it is REACH & RoHS compliant, making it a wide-temperature drop-in alternative to the HR871190A.

Notes:
- All table parameters are taken strictly from the two datasheets (HanRun HR871190A / VOOHU SYT511Q293AC1A8D057); only items specified by both and matchable one-to-one are listed. Items missing on either side are not tabulated.
- OCL, turn ratio and isolation (both 2250VDC) match; VOOHU improves on insertion loss (≤1.0dB vs 1.1dB) and CMR (-30dB vs -20dB), and its operating range of -40 to +85°C exceeds HanRun's 0 to +70°C.
- Dielectric test conditions differ slightly: HanRun specifies 2250VDC 0.5mA 60s, VOOHU 2250VDC 1mA 6s; both are rated 2250VDC.
- Return loss and crosstalk use slightly different frequency bands (see table); both meet typical 100/1000Base-T magnetics requirements.
- The HanRun HR871190A datasheet does not list storage temperature, housing/terminal materials, durability or mating force; VOOHU specifies storage -40 to +85°C, housing PBT (UL94V-0), brass C2680 0.20mm nickel-plated shield, phosphor bronze C5210 0.35mm / 6µ″ gold terminals, ≥750-cycle durability and ≤23N mating force. These are omitted from the table because the competitor does not specify them.
- Pinout and footprint: both are Tab-Up single-port gigabit magjacks with green/yellow bi-color LEDs (green 11/12, yellow 13/14). Please confirm full pin/footprint compatibility against the actual PCB layout and samples.
4. Applications
- 1000Base-T gigabit Ethernet interfaces for server/PC NICs, switches and routers.
- Gigabit ports in industrial Ethernet, security/surveillance and gateways requiring -40 to +85°C operation.
- Equipment requiring link/speed status indication via green/yellow bi-color LEDs.
- Gigabit Ethernet ports requiring 2250VDC isolation.
5. FAQ
Q1: Can the VOOHU SYT511Q293AC1A8D057 replace the HanRun HR871190A?
Both are single-port Tab-Up RJ45 jacks with integrated gigabit (100/1000Base-T) magnetics; OCL 350µH, turn ratio 1CT:1CT and isolation 2250VDC match, and the green/yellow bi-color LED layout (green 11/12, yellow 13/14) is identical, so the VOOHU part is a pin-to-pin replacement candidate. VOOHU also improves on insertion loss, CMR and operating range. Sample validation on the actual PCB is recommended.
Q2: What are the main differences?
VOOHU offers lower insertion loss (≤1.0dB vs 1.1dB), stronger CMR (-30dB vs -20dB) and a wider operating range (-40 to +85°C vs 0 to +70°C), better suited to industrial and outdoor use.
Q3: Is it gigabit? Does it support 100M?
Yes, it is a 1000Base-T gigabit magnetics module with four 1CT:1CT pairs; HanRun is rated 100/1000Base-TX and is backward compatible with 100M.
Q4: Are samples available?
Yes. Sample orders ship within 48 hours and arrive within 7 days.
