Compiled from both manufacturers' published datasheets. Verify with samples and the PCB footprint before production.
The VOOHU SYT511Q218AC1A8D057 is a replacement candidate 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).
#1. Competitor Product Overview (Pulse Electronics, a YAGEO company)
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.
#2. VOOHU Replacement Overview (Suzhou VOOHU Electronic Technology Co., Ltd.)
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. It has the same outline, panel cutout and PCB hole pattern as the competitor.
#3. Key Parameter Comparison
The table below uses the Pulse JXD3-0002NL datasheet parameters as the baseline, with the corresponding VOOHU SYT511Q218AC1A8D057 specs filled in (only parameters specified by both and matchable one-to-one are listed).
Notes:
- 1.The Pulse datasheet additionally specifies insertion loss ≤1.2dB Max at 100–125MHz and DC resistance ≤1.2Ω; these are not separately listed on the VOOHU datasheet and are therefore excluded from the table.
- 2.The VOOHU datasheet additionally specifies durability ≥750 mating cycles and mating force ≤23N (not listed on the Pulse datasheet).
- 3.Return loss and crosstalk: VOOHU is specified in finer frequency bands and meets or exceeds Pulse in every corresponding band; insertion loss, CMR, isolation and temperature range are identical, while the VOOHU turn-ratio tolerance is tighter (±2% vs ±5%).
- 4.Contact gold plating: Pulse specifies 30µ″ Min, the VOOHU standard is 6µ″; gold thickness can be customized on request.
- 5.Both parts share the same outline, panel cutout and PCB hole pattern (10×Ø0.9 + 2×Ø1.6 + 2×Ø3.2 + 4×Ø1.2), so the footprint is the same; please verify pinout and EMI grounding tabs against physical samples before mass production.
- 6.All values are taken from the two datasheets with Typ/Min/Max qualifiers preserved; the latest datasheet prevails.
#4. Applications
- 1.RJ45 ports of Gigabit Ethernet switches, routers, gateways and modems.
- 2.Gigabit network interfaces of IP cameras, NVRs and security/surveillance equipment.
- 3.1000BASE-T wired connections for industrial Ethernet, PLCs and industrial control boards.
- 4.Servers, NICs, desktop motherboards and various Gigabit network terminals.
#5. FAQ
Can VOOHU SYT511Q218AC1A8D057 replace Pulse JXD3-0002NL?
It is a replacement candidate. 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. Please confirm pinout and EMI tabs against samples before mass production.
Are the key electrical parameters compatible?
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.
