RJ45 Integrated Magnetics Connector: VOOHU SYT111B002FA2A1D as a Replacement for Pulse JX0011D21BNL — Comparison Report

The VOOHU SYT111B002FA2A1D is a pin-to-pin drop-in replacement for the Pulse (a YAGEO company) JX0011D21BNL: both are industrial -40 to +85°C 1×1 Tab-Down 100Base RJ45 integrated magnetics connectors with compatible pinout and mounting, at better cost-effectiveness and stable supply.

1. Competitor Product Overview (Pulse Electronics, a YAGEO company)

The Pulse JX0011D21BNL is an industrial extended-temperature PulseJack from Pulse — a 100BASE-TX 1×1 Tab-Down RJ45 integrated connector module (ICM) with magnetics, 8-pin, with EMI shielding fingers (enhanced EMI, AutoMDIX / Non-AutoMDIX option) and green/yellow (G/Y) LEDs. It meets IEEE 802.3 across the full -40 to +85°C range, peak solder temperature 260°C, with an industry-standard RJ-45 pinout compatible with existing PulseJacks.

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

The VOOHU SYT111B002FA2A1D is an ideal drop-in alternative offering equivalent function with better cost-effectiveness and stable supply. It is a 100BASE 1×1 Tab-Down RJ45 integrated magnetics connector with 8 signal pins and dual-color (green/yellow) LEDs, built for an industrial -40 to +85°C range; its pin definition and mounting are compatible with the JX0011D21BNL for a pin-to-pin drop-in replacement.

3. Key Parameter Comparison

The table below uses the Pulse JX0011D21BNL datasheet parameters as the baseline, with the corresponding VOOHU SYT111B002FA2A1D specs filled in (only parameters specified by both and matchable one-to-one are listed).

Notes:

  1. Both are 1×1 Tab-Down 100Base RJ45 integrated magnetics connectors with 8 signal pins and dual-color LEDs; pin definition and mounting are compatible (Pulse uses an industry-standard RJ-45 pinout) for a pin-to-pin drop-in replacement. Verify the PCB footprint and panel cutout against both drawings.
  2. Both operate at -40 to +85°C (industrial wide-temp) — the temperature grade is identical.
  3. Specification basis: Pulse states insertion loss / return loss / crosstalk / CMR as Typ (typical), while VOOHU states them as Min/Max (guaranteed limits).
  4. Isolation is 1500 on both sides (Pulse 1500 Vrms; VOOHU 1500 VAC, plus a guaranteed 2250 VDC). Turns ratio, crosstalk, durability (750 cycles) and wave-solder temperature (260°C) are identical.
  5. The Pulse JX0011D21BNL includes EMI shielding fingers (enhanced EMI); if your design relies on EMI fingers, confirm the shielding/grounding configuration with VOOHU. The Pulse datasheet does not state OCL (VOOHU is 350 µH Min) and storage temperature is stated only by VOOHU, so both are omitted from the table.

4. Applications

  1. Ethernet switches and routers (including hubs and SOHO devices).
  2. Server / PC LAN-on-Motherboard (LOM) and network interface cards (NIC).
  3. Industrial Ethernet, edge gateways and SCADA: the -40 to +85°C range fits factory environments.
  4. Security & surveillance (IP cameras, NVR/DVR).
  5. Other 100M-Ethernet devices with industrial wide-temperature or EMI requirements.

5. FAQ

Q1: Are VOOHU SYT111B002FA2A1D and Pulse JX0011D21BNL pin-compatible for a direct swap?
A: Yes. Both are 1×1 Tab-Down 100Base RJ45 integrated magnetics connectors with 8 signal pins and green/yellow LEDs; pin definition and mounting are compatible (Pulse uses an industry-standard RJ-45 pinout). Confirm the PCB footprint and panel cutout against the drawings and they swap directly.

Q2: Are the two products in the same temperature grade?
A: Yes. Both operate at -40 to +85°C (industrial wide-temp), suitable for industrial Ethernet and environments with large temperature swings.
