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.

#3. Key Parameter Comparison

The table below uses the HanRun HR871150C datasheet parameters as the baseline, with the corresponding VOOHU SYT111B032DB1A1DPQ specs filled in (only parameters specified by both and matchable one-to-one are listed).

Notes:

1. 1.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.
2. 2.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.
3. 3.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.
4. 4.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.
5. 5.Contact plating: HanRun specifies 30µ″ gold over 50µ″ nickel, while VOOHU specifies 6µ″ gold; heavier gold plating is available from VOOHU on request.
6. 6.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

1. 1.10/100Base-T network interfaces for switches, routers, PoE PSE and PD equipment.
2. 2.RJ45 ports of PoE end devices such as IP cameras, wireless APs and IP phones.
3. 3.Industrial Ethernet and security/surveillance applications requiring -40 to +85°C wide-temperature operation.
4. 4.Equipment requiring link/speed status indication via yellow/green bi-color LEDs.

#5. FAQ

QCan 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.

QWhat 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.

QDoes 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.

QAre samples available?

Yes. Sample orders ship within 48 hours and arrive within 7 days.
