RJ45 network port integrated network transformer: VOOHU SYT511Q293AC1A8D057 replaces HanRun HR871190A comparison report

1. Product introduction of friendly merchants (HanRun HanRun Electronics)

HanRun (HanRun Electronics Company Limited) is a manufacturer of connectors and magnetic components located in Zhongshan, Guangdong. HR871190A is a 1×1 single-port Tab-Up RJ45 network port with integrated network transformer. It is designed for Gigabit Ethernet applications such as 100/1000Base-TX network card (NIC). It contains four pairs of 1CT:1CT network transformers and green/yellow dual-color LEDs, and is RoHS compliant. Its open circuit inductance is 350µH, insertion loss ≤1.1dB, common mode rejection -20dB, isolation withstand voltage 2250VDC, and operating temperature 0~+70°C.

2. Introduction to VOOHU alternative products (Suzhou Wohu Electronic Technology Co., Ltd.)

VOOHU SYT511Q293AC1A8D057 is designed and manufactured by Suzhou Wohu Electronic Technology Co., Ltd. It is an integrated network transformer for Tab-Up single-port RJ45 network port, oriented to 1000Base-T Gigabit Ethernet applications. This material number is consistent with HR871190A in key indicators such as open-circuit inductance (350µH), turns ratio (1CT:1CT), and isolation withstand voltage (2250VDC), and is superior in insertion loss (≤1.0dB, better than 1.1dB) and common-mode rejection (-30dB, better than -20dB); it integrates the same green/yellow dual-color LED (green 11/12, Huang 13/14). At the same time, the operating temperature is extended to -40~+85°C, compliant with REACH and RoHS, and is more suitable for industrial and outdoor wide-temperature environments. It can be used as an alternative to HR871190A.

3. Comparison of core parameters

The following table is based on the parameters listed in the HanRun HR871190A data sheet, and corresponds to the specifications of VOOHU SYT511Q293AC1A8D057 (only parameters that are clearly marked by both parties and can correspond one to one are listed).

Note:

1. The parameters in this table are extracted strictly based on the specifications of both parties (HanRun HR871190A / VOOHU SYT511Q293AC1A8D057). Only items that are clearly marked by both parties and can be matched one-to-one are listed; items that are missing or cannot be matched by either party are not included in the table.
2. Key items such as open circuit inductance (OCL), turns ratio, and isolation withstand voltage (both 2250VDC) are consistent; VOOHU is better in insertion loss (≤1.0dB vs 1.1dB) and common mode rejection (-30dB vs -20dB), and its operating temperature -40~+85°C is also better than HanRun 0~+70°C.
3. The isolation withstand voltage test conditions are slightly different: HanRun is marked 2250VDC 0.5mA 60s, VOOHU is marked 2250VDC 1mA 6s; both have rated withstand voltages of 2250VDC.
4. The return loss and crosstalk frequency band divisions are slightly different (see table); both meet the general requirements of 100/1000Base-T network transformers.
5. HanRun HR871190A specifications do not list the storage temperature, shell/terminal material, plugging life and insertion force; VOOHU label: storage temperature -40~+85°C, shell PBT (UL94V-0), shielding case brass C2680 0.20mm nickel plated, terminal phosphor bronze C5210 0.35mm/6µ″ gold, plugging life ≥750 times, insertion force ≤23N. These items are not included in the comparison table because they are not marked by the competitors.
6. Pinout and package: Both are Tab-Up single-port gigabit magjack, green/yellow dual-color LED (green 11/12, yellow 13/14). It is recommended to use the actual PCB Layout and samples to confirm that the pins and packages are fully compatible.

4. Applicable scenarios

1. Server/PC network card (NIC), switch, router, etc. 1000Base-T Gigabit Ethernet interface.
2. Industrial Ethernet, security monitoring, gateways, etc. require Gigabit network ports with wide temperature operation of 40~+85°C.
3. Devices requiring link/rate status indication (green/yellow dual-color LED indication).
4. Gigabit Ethernet ports that require an isolation voltage of 2250VDC.

5. Frequently Asked Questions (FAQ)

Q1: Can VOOHU SYT511Q293AC1A8D057 replace HanRun HR871190A?

Both are single-port Tab-Up RJ45 network ports with integrated Gigabit (100/1000Base-T) network transformers. The open-circuit inductance is 350µH, the turns ratio is 1CT:1CT, and the isolation withstand voltage is 2250VDC. The green/yellow two-color LED configuration (green 11/12, yellow 13/14) is the same, and can be used as a pin-to-pin replacement candidate; VOOHU It is better in terms of insertion loss, common mode suppression and operating temperature. It is recommended to use actual PCB for sample verification.

Q2: What are the main differences between the two?

VOOHU has insertion loss ≤1.0dB (HanRun 1.1dB), better common mode rejection -30dB (HanRun -20dB), and wider operating temperature -40~+85°C (HanRun 0~+70°C), making it more suitable for industrial and outdoor environments.

Q3: Is it Gigabit? Does it support 100M?

It is a Gigabit 1000Base-T network transformer, including four pairs of 1CT:1CT; HanRun is nominally 100/1000Base-TX and is backward compatible with 100M applications.

Q4: Can you provide samples?

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