Compiled from both manufacturers' published datasheets. Verify with samples and the PCB footprint before production.
1. Competitor Product Overview (Pulse Electronics / YAGEO)
Pulse Electronics (a YAGEO Company) HX5120NL (Tape & Reel: HX5120NLT) is a 1000BASE-T quad-channel low-profile SMD transformer module in a 24-pin package, IEEE 802.3 compliant, J-STD-020 Level 1 (no moisture sensitivity), peak reflow 245°C, RoHS compliant. With a maximum height of only 2.08 mm, it is designed for space-constrained Gigabit Ethernet interfaces, with an operating temperature of -40°C to +85°C.
#2. VOOHU Replacement Product (Su Zhou Voohu Electronic Tech. Co., Ltd.)
VOOHU WHSG24301GM is the ideal drop-in replacement offering equivalent functionality with superior cost-effectiveness and supply stability. It is a 100/1000BASE-T quad-channel low-profile SMD transformer module in a pin-compatible 24-pin package, with identical circuit topology (1CT:1CT × 4 channels), a wider operating temperature range (-40°C to +125°C), additional GJB9001C (Chinese military quality standard) certification and IEEE 802.3ab compliance, allowing direct substitution for the Pulse HX5120NL.
#3. Key Parameter Comparison
The table below maps Pulse product page parameters to VOOHU WHSG24301GM specifications. Yellow-highlighted cells indicate notable differences.
Notes: ① Operating temp: VOOHU -40°C to +125°C significantly wider than Pulse -40°C to +85°C. ② Height: VOOHU 2.85 mm vs Pulse 2.08 mm — both low-profile; verify clearance in the target system. ③ Return loss: VOOHU better at 1-30 MHz (-18 dB vs -16 dB). ④ Crosstalk/CMR: Pulse specifies strict low-frequency Min values via formula; VOOHU provides flat guaranteed minimums — bench validation at 1000BASE-T operating frequencies recommended.
#4. Application Scenarios
1000BASE-T quad-channel low-profile transformer modules are widely used in the following applications:
- 1.Gigabit Ethernet Switches and Routers
Suitable for enterprise and industrial-grade Gigabit switches and routers. Quad-channel integration reduces PCB footprint; low-profile packaging (height < 3 mm) meets thin-device space requirements.
- 1.Server Motherboards and Network Interface Cards (NIC)
Ideal for server motherboards and Gigabit NICs. VOOHU WHSG24301GM's wide temperature range (-40°C to +125°C) accommodates data center high-temperature operation and industrial server environments.
- 1.Military and High-Reliability Electronics
GJB9001C military quality management certification makes WHSG24301GM suitable for military communication equipment, shipborne/airborne electronics, and high-reliability industrial systems with strict quality traceability requirements.
- 1.Industrial Ethernet and Edge Computing Gateways
Suitable for industrial switches, edge gateways, and SCADA systems. The -40°C to +125°C operating range covers harsh factory environments; 1500 VAC isolation ensures safety.
- 1.Telecom Infrastructure and Access Equipment
Applicable to DSL/fiber access devices and small-cell backhaul modules. Low-profile design enables high-density integration; 100/1000BASE-T dual-speed capability supports auto-negotiation.
#5. Frequently Asked Questions (FAQ)
Is VOOHU WHSG24301GM fully pin-compatible with Pulse HX5120NL? Can it be replaced without a PCB change?
Yes. Both products use a 24-pin low-profile SMD package with 1.27 mm pitch and identical channel topology (4 channels, 1CT:1CT each). VOOHU WHSG24301GM can be directly substituted without PCB redesign. Please verify the target system's height clearance (Pulse 2.08 mm vs VOOHU 2.85 mm).
Is VOOHU WHSG24301GM RoHS compliant and environmentally certified?
Yes. VOOHU WHSG24301GM carries RoHS/REACH/HF certification, free of lead, mercury, cadmium, and other restricted substances, meeting EU and major market environmental regulations. It supports lead-free reflow, compatible with standard SMT production lines.
