#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 FRJ45041-1301K6K1100 referenced here belongs to its FRJ45041 RJ45-connector series: a 1-port 8P8C, 90° sunk-board (4.2mm drop) through-hole (DIP) jack with a black LCP UL94V-0 housing, phosphor-bronze contacts with selective 1μ″ gold in the contact area (tin on tail), a nickel-plated brass shell and Left-Yellow / Right-Green LEDs, rated for an operating temperature of -20℃ to +75℃, used in the Ethernet ports of switches, networking and security equipment.
- 1.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 SYT-CB4.2YGZNL is an RJ45 sunk-board (4.2mm) through-hole jack, shielded and with LEDs (8P8C, 90°); its housing is black flame-retardant LCP UL94V-0, its contacts are phosphor bronze (T=0.35mm) with gold plating in the contact area, and the shield is C2680 brass (T=0.20mm) fully nickel-plated, with Left-Yellow / Right-Green LEDs; the drawing is marked REACH & RoHS. With an operating temperature of -40℃ to +85℃ and contact resistance as low as 30 mΩ Max, its electrical, mechanical and material parameters fully correspond to — and in several respects exceed — the TXGA FRJ45041-1301K6K1100, making it a drop-in Pin-to-Pin replacement.
- 1.Key Parameter Comparison
The table below uses the TXGA FRJ45041-1301K6K1100 datasheet parameters as the baseline, with the corresponding VOOHUSYT-CB4.2YGZNL specs filled in (only parameters specified by both and matchable one-to-one are listed).
Notes:
- 1.Operating temperature: VOOHU is -40℃~+85℃ (industrial wide-temperature), while TXGA is -20℃~+75℃; VOOHU's wider range better suits industrial, outdoor and high/low-temperature environments.
- 2.Contact resistance: VOOHU is 30 mΩ Max initial (≤50 mΩ Max after durability testing), while TXGA is 40 mΩ Max; VOOHU's lower contact resistance means less signal loss and less contact heating.
- 3.The VOOHU datasheet additionally specifies: insertion force 2.2 KGF Max (~21.6N), retention strength 7.7 KGF (~75.5N, between plug and jack), durability 750 cycles (12.5mm/min), storage temperature -40℃~+85℃ and LED optical parameters (Yellow 585nm, Green 568nm, 20mA); the TXGA drawing does not list these items, so they are excluded from the comparison table.
- 4.Contact gold: TXGA uses selective 1μ″ gold in the contact area (tin on tail); VOOHU uses gold in the contact area (the drawing does not state a specific micro-inch thickness) — please confirm plating requirements before mass production.
- 5.The two share the same PCB pad / locating layout (7.14mm signal span, 14.00×16.08 locating, Ø0.90 signal holes) and the same 4.2mm sunk-board height, so the footprint is interchangeable; mechanical tolerances differ slightly — verify against physical samples.
- 6.LED pin definitions are identical (Left-Yellow / Right-Green, LEDs on pins 9–12); please verify polarity orientation on the PCB.
- 7.Applications
- 8.Sunk-board RJ45 network ports of switches, routers and gateways (used with on-board magnetics or PoE designs).
- 9.Ethernet interfaces of industrial-Ethernet equipment, industrial PCs, PLCs and network modules — especially wide-temperature environments.
- 10.Network ports of IP cameras, NVRs, access-control and security devices.
- 11.RJ45 interfaces of network terminals and smart devices that require a low panel height / flush sunk-board mounting.
- 12.FAQ
Can the VOOHU SYT-CB4.2YGZNL directly replace the TXGA FRJ45041-1301K6K1100?
Both are 1-port 8P8C, 90° sunk-board 4.2mm DIP RJ45 jacks with LEDs. Their voltage/current rating, insulation resistance, withstanding voltage, housing material (LCP UL94V-0), shield and LED configuration (L: Yellow / R: Green) match, and the PCB footprint and 4.2mm sunk-board height align. It works as a Pin-to-Pin replacement; please confirm housing and mounting-hole dimensions against physical samples before mass production.
What advantages does VOOHU offer over this TXGA part?
Two main ones: a wider operating temperature (VOOHU -40℃~+85℃ vs TXGA -20℃~+75℃), better suited to industrial and outdoor wide-temperature use; and lower contact resistance (VOOHU 30 mΩ Max initial vs TXGA 40 mΩ Max), meaning less signal loss and heating. VOOHU's datasheet also provides more complete parameters such as insertion force, retention strength, durability and storage temperature.
Is this a magjack (RJ45 with integrated magnetics)?
No. This model is an RJ45 sunk-board 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.
Is it RoHS / REACH compliant?
Yes. The VOOHU SYT-CB4.2YGZNL drawing is marked REACH & RoHS COMPLIANT, and the housing uses LCP UL94V-0 flame-retardant material, meeting mainstream environmental and flammability requirements.
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.
