RJ45 Integrated Magnetics Connector: VOOHU SYT111B032DB1A1DPQ as a Replacement for HanRun HR871150C
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 HR871150C is a single-port RJ45 connector with integrated 10/100Base-T magnetics and a yellow/green bi-color LED, supporting PoE (57VDC, 350mA per centre tap; 17.5W with 2 taps, 35W with 4 taps) and RoHS compliant. It specifies OCL 350µH, insertion loss ≤1.0dB, CMR -30dB, isolation 2250VDC and an operating range of 0 to +70°C, and is widely used in the network interfaces of switches and PoE PSE/PD equipment.
2. VOOHU Replacement Overview (Suzhou VOOHU Electronic Technology Co., Ltd.)
The VOOHU SYT111B032DB1A1DPQ, designed and manufactured by Suzhou VOOHU Electronic Technology Co., Ltd., is a Tab-Down single-port RJ45 connector with integrated magnetics for 10/100Base-T PoE applications, suitable for PSE or PD per IEEE 802.3af. It matches the HR871150C on key specifications — OCL (350µH), insertion loss (≤1.0dB), CMR (-30dB), PoE capability (57VDC/350mA) and durability (≥750 cycles) — and provides the same yellow/green bi-color LED indication. In addition, its operating temperature is extended to -40 to +85°C and it is REACH & RoHS compliant, making it well suited to wide-temperature industrial and outdoor environments as a drop-in alternative to the HR871150C.

Notes:
- All table parameters are taken strictly from the two datasheets (HanRun HR871150C / VOOHU SYT111B032DB1A1DPQ); only items specified by both and matchable one-to-one are listed. Items missing on either side are not tabulated.
- OCL, insertion loss, CMR, storage temperature and durability are stated identically by both parts; VOOHU's operating range of -40 to +85°C exceeds HanRun's 0 to +70°C, making it better suited to wide-temperature industrial/outdoor use.
- Return loss and crosstalk use slightly different frequency bands: VOOHU specifies return loss in four bands over 1–80MHz and crosstalk in three bands over 1–100MHz, while HanRun states crosstalk as a single -30dB over 1–100MHz. Both meet typical 10/100Base-T magnetics requirements.
- Dielectric test conditions differ: HanRun specifies isolation 2250VDC 0.5mA 60s; VOOHU specifies Hi-Pot 500VAC and is 100% tested to IEEE 802.3 isolation requirements. If a specific withstand voltage (e.g. 2250VDC) is mandatory, please confirm with VOOHU.
- Contact plating: HanRun specifies 30µ″ gold over 50µ″ nickel, while VOOHU specifies 6µ″ gold; heavier gold plating is available from VOOHU on request.
- Pinout and footprint: both are Tab-Down single-port jacks with integrated magnetics and yellow/green bi-color LEDs (yellow 11/12, green 13/14); VOOHU is marked "no pin 6". Please confirm full pin/footprint compatibility against the actual PCB layout and samples.
4. Applications
- 10/100Base-T network interfaces for switches, routers, PoE PSE and PD equipment.
- RJ45 ports of PoE end devices such as IP cameras, wireless APs and IP phones.
- Industrial Ethernet and security/surveillance applications requiring -40 to +85°C wide-temperature operation.
- Equipment requiring link/speed status indication via yellow/green bi-color LEDs.
5. FAQ
Q1: Can the VOOHU SYT111B032DB1A1DPQ replace the HanRun HR871150C?
Both are single-port RJ45 connectors with integrated 10/100Base-T PoE magnetics. Their core electrical specs (OCL 350µH, insertion loss ≤1.0dB, CMR -30dB, 57VDC/350mA PoE) match and the bi-color LED configuration is identical, so the VOOHU part is a pin-to-pin replacement candidate; sample validation on the actual PCB is recommended.
Q2: What are the main differences?
VOOHU's operating temperature is -40 to +85°C (HanRun is 0 to +70°C), making it better for wide-temperature industrial and outdoor environments; VOOHU also specifies finer return-loss/crosstalk bands. Other key parameters are essentially identical.
Q3: Does it support PoE, and at what power?
Yes, per IEEE 802.3af, 57VDC continuous and 350mA per centre tap; HanRun rates 17.5W with 2 taps / 35W with 4 taps.
