RJ45 Jack Connector : VOOHU WH56A31882021103 as a Replacement for TXGA FRJ45012-1103K6K1200

Competitor Product Overview (TXGA (TXGA Industrial Electronic Co., Ltd.))

TXGA (TXGA Industrial Electronic Co., Ltd., Shenzhen) is a connector and cable-assembly manufacturer whose product range covers RJ45 network connectors, M16 circular connectors, wire-to-board / board-to-board connectors, aviation plugs and industrial-grade connectors, with customization support. The FRJ45012-1103K6K1200 referenced here belongs to its FRJ45 RJ45-connector series: a 1-port 8P8C, 90° right-angle through-hole (DIP) jack with phosphor-bronze contacts, 3μ″ gold plating, a black PBT housing and Left-Yellow / Right-Green LEDs, widely used in the Ethernet ports of switches, industrial-network and security equipment.

2. VOOHU Replacement Overview (Suzhou VOOHU Electronic Technology Co., Ltd.)

Suzhou VOOHU Electronic Technology Co., Ltd. (VOOHU) is an original manufacturer integrating connectors, magnetics and interface ICs, with two in-house factories, ISO9001 / ISO14001 certification and RoHS / REACH compliance. The WH56A31882021103 is a 56S-series 1×1 8P8C RJ45 jack with LEDs in a 90° right-angle through-hole design; its contacts use C51000 phosphor bronze with 3μ″ gold-over-nickel plating, the shell is H65Y brass with nickel plating and EMI shielding, the LEDs are Left-Yellow / Right-Green, and the UL94V-0 housing is REACH & RoHS compliant. Its electrical, mechanical and environmental parameters fully correspond to the TXGA FRJ45012-1103K6K1200, making it a drop-in Pin-to-Pin replacement.

3. Key Parameter Comparison

The table below uses the TXGA FRJ45012-1103K6K1200 datasheet parameters as the baseline, with the corresponding VOOHU WH56A31882021103 specs filled in (only parameters specified by both and matchable one-to-one are listed).

Notes:

1.  All parameters above are taken from items explicitly specified by both datasheets and matchable one-to-one; items specified by only one side (e.g., VOOHU also lists a storage temperature of -40℃~+85℃ at RH<70%, while the TXGA datasheet does not list storage temperature separately) are not included in the table.
2.  Mating/unmating force: TXGA specifies 30N Max and VOOHU 20N Max (both upper limits); VOOHU's lower force means smoother insertion/withdrawal and less stress on the PCB.
3.  Gold plating thickness is 3μ″ on both (VOOHU drawing REMARK marks “gold 3U”; TXGA order-code position 5, 03 = 3μ″); both use gold-plated phosphor-bronze contacts with comparable contact reliability.
4.  Dielectric withstanding voltage is 1000V AC on both: VOOHU marks the test condition as 50/60Hz for 1 minute, and TXGA marks it as r.m.s; the withstanding level is equivalent.
5.  The two share the same PCB pad / locating-hole layout (signal pins at 1.02mm pitch, 7.14mm span, 9.14×12.70 locating), so the footprint is interchangeable; mechanical tolerances differ slightly (VOOHU ±0.2, TXGA ±0.25) — verify against physical samples before mass production.
6.  LED pin definitions are identical (Left-Yellow / Right-Green, LEDs on pins 9–12); please verify polarity orientation on the PCB.

8. Applications

9.  RJ45 network ports of switches, routers and gateways (used with on-board magnetics or PoE designs).
10.  Ethernet interfaces of industrial-Ethernet equipment, industrial PCs, PLCs and network modules.
11.  Network ports of IP cameras, NVRs, access-control and security devices.
12.  RJ45 data interfaces with status LEDs on servers, set-top boxes and smart terminals.

14. FAQ

Q1: Can the VOOHU WH56A31882021103 directly replace the TXGA FRJ45012-1103K6K1200?

Yes. Both are 1-port 8P8C, 90° right-angle DIP RJ45 jacks with LEDs. Their core parameters — voltage/current rating, contact resistance, insulation resistance, withstanding voltage, 3μ″ gold plating, LED configuration (L: Yellow / R: Green) and operating temperature — match, and the PCB footprints align, so it works as a Pin-to-Pin replacement. Please confirm housing and mounting-hole dimensions against physical samples before mass production.

Q2: Does the difference in mating/unmating force matter?

TXGA specifies 30N Max and VOOHU 20N Max — both are upper limits. VOOHU's lower force means easier insertion/withdrawal and less stress on solder joints and the PCB, benefiting long-term reliability.

Q3: Is this a magjack (RJ45 with integrated magnetics)?

No. This model is an RJ45 jack with LEDs but WITHOUT integrated magnetics (8P8C signal contacts + L-Yellow / R-Green LEDs); the network transformer must be placed separately on the PCB or handled by a PoE design. If you need an RJ45 with integrated magnetics (magjack), VOOHU offers a full range of part numbers — please contact us for selection.

Q4: Is it RoHS / REACH compliant?

Yes. The VOOHU WH56A31882021103 drawing is marked REACH & RoHS COMPLIANT, and the housing uses UL94V-0 flame-retardant material, meeting mainstream environmental and flammability requirements.

Q5: Can gold thickness, LED color or packaging be customized?

Yes. VOOHU supports customization of contact gold thickness, LED color (e.g., Left-Green / Right-Yellow), shield structure and packaging, with samples and technical support. Sample orders ship within 48 hours and arrive within 7 days. Technical support: song.lei@voohu.cn; WEB: www.voohuele.com; TEL: +86 400 1048 018.
