VOOHU SYT511Q218AC1A8D057 as a Drop-in Replacement for Pulse Electronics JXD3-0002NL

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.

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. With the same outline, panel cutout and PCB hole pattern as the competitor, it enables pin-to-pin replacement.

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 (10ר0.9 + 2ר1.6 + 2ר3.2 + 4ר1.2), making them a same-footprint drop-in design; 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.
