The VOOHU SYT511Q218AC1A8D057 is a pin-to-pin drop-in replacement for the Pulse Electronics (a YAGEO company) JXD3-0002NL: both are single-port Tab-Up Gigabit 1000BASE-T integrated-magnetics RJ45 jacks with the same outline, panel cutout and PCB hole pattern and matching core electrical specs (with a tighter ±2% turn-ratio tolerance), enabling pin-to-pin replacement.
Pulse Electronics is a globally recognized supplier of magnetics and connectors, now a YAGEO company. Its PulseJack™ integrated-magnetics RJ45 connectors are widely used in Ethernet equipment. The reference part JXD3-0002NL is a single-port (1×1) Tab-Up Gigabit 1000BASE-T integrated-magnetics RJ45 jack with an on-board 1CT:1CT network transformer and yellow/green LEDs: turn ratio 1:1 (±5%), primary inductance 350µH Min, insertion loss ≤1.0dB (1–100MHz), crosstalk and CMR ≥30dB, primary-to-secondary isolation 2250VDC, operating −40~+85°C, RoHS compliant.
Suzhou VOOHU Electronic Technology Co., Ltd. (VOOHU) focuses on the R&D and manufacturing of connectors and magnetics, including RJ45 connectors, network transformers, PoE modules and SFP connectors. The replacement part SYT511Q218AC1A8D057 is a single-port Tab-Up Gigabit 1000BASE-T integrated-magnetics RJ45 jack: PBT housing (UL94 V-0), C2680 nickel-plated shield, phosphor-bronze C5210 contacts with a gold-plated contact area. Its electrical performance matches JXD3-0002NL — turn ratio 1:1 (±2%, tighter), OCL 350µH Min, insertion loss ≤1.0dB, CMR ≥30dB, isolation 2250VDC, operating −40~+85°C — and its return loss and crosstalk meet or exceed the competitor in every band; durability ≥750 cycles, mating force ≤23N. With the same outline, panel cutout and PCB hole pattern as the competitor, it enables pin-to-pin replacement.

Notes:
Q1: Can VOOHU SYT511Q218AC1A8D057 directly replace Pulse JXD3-0002NL?
A: Yes. Both are single-port Tab-Up Gigabit integrated-magnetics RJ45 jacks with identical outline, panel cutout and PCB hole pattern and matching core electrical specs; VOOHU meets or exceeds the competitor on return loss and crosstalk, enabling pin-to-pin replacement. Please confirm pinout and EMI tabs against samples before mass production.
Q2: Are the key electrical parameters compatible?
A: Yes. Turn ratio 1:1 (VOOHU ±2%, tighter), OCL 350µH Min, insertion loss ≤1.0dB, CMR ≥30dB, isolation 2250VDC and operating temperature −40~+85°C are identical; the VOOHU return loss and crosstalk meet or exceed the competitor in every band.
Q3: Do you support customization?
A: Yes. LED color, gold plating thickness, tab orientation and tray/tape-and-reel packaging can be customized. Technical support: song.lei@voohu.cn, Tel +86 400 1048 018, Web www.voohuele.com.
