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) H7008NL is a high-performance 10GBASE-T quad-channel SMD transformer module in a 24-pin package, compliant with IEEE 802.3, J-STD-020 Level 1 (no moisture sensitivity), peak reflow 245°C, and RoHS compliant. It supports up to 500 MHz bandwidth and is widely used in 10G Ethernet interface designs, with an operating temperature of 0°C to +70°C.
#2. VOOHU Replacement Product (Su Zhou Voohu Electronic Tech. Co., Ltd.)
VOOHU WHSM24P02N0 is the ideal drop-in replacement offering equivalent functionality with superior cost-effectiveness and supply stability. It is a 10G BASE-T quad-channel SMD transformer module in a pin-compatible 24-pin package, with an identical circuit topology (1CT:1CT × 4 channels) and a wider operating temperature range (-40°C to +85°C), allowing direct substitution for the Pulse H7008NL without PCB redesign.
#3. Key Parameter Comparison
The table below maps Pulse product page parameters to VOOHU WHSM24P02N0 specifications. Yellow-highlighted cells indicate notable differences.
Notes:
① VOOHU operating temp is significantly wider (-40°C to +85°C).
② Insertion/return loss performance is comparable in the core 1-200 MHz band; above 200 MHz VOOHU insertion loss is slightly higher — evaluate for your target frequency range.
③ Crosstalk/CMR: Pulse specifies Min values; VOOHU specifies Typ values — different presentation styles.
④ OCL: VOOHU 120 uH vs Pulse 200 uH; both exceed the IEEE 802.3 minimum — bench validation recommended.
#4. Application Scenarios
10GBASE-T quad-channel transformer modules are widely used in the following applications:
- 1.10G Ethernet Switches and Routers
Suitable for data center and enterprise-grade 10G switches and routers. Quad-channel integration reduces PCB footprint and simplifies high-density board design.
- 1.Servers and Network Interface Cards (NIC)
Ideal for server motherboards and NICs. VOOHU WHSM24P02N0's -40°C to +85°C operating range accommodates server rooms and edge computing nodes.
- 1.Industrial Ethernet and Edge Computing
Suitable for industrial switches, routers, and edge gateways. The wide temperature range and 1500 VAC isolation meet demanding industrial environment requirements.
- 1.Network Security and Firewall Appliances
Applicable to enterprise firewalls and intrusion detection systems requiring high-speed, low-latency Ethernet interfaces. Quad-channel integration increases port density.
- 1.Storage Networks (NAS/SAN) and HCI
Suitable for NAS, SAN controllers, and hyper-converged infrastructure nodes. Supports 10GBASE-T standard and is compatible with mainstream 10G PHY chips.
#5. Frequently Asked Questions (FAQ)
Is VOOHU WHSM24P02N0 fully pin-compatible with Pulse H7008NL? Can it be replaced without a PCB change?
Yes. Both products use a 24-pin SMD package with 1.00 mm pin pitch and identical channel topology (4 channels, 1CT:1CT each). VOOHU WHSM24P02N0 can be directly substituted without any PCB redesign.
VOOHU WHSM24P02N0 has a much wider operating temperature (-40°C to +85°C) vs Pulse (0°C to +70°C). What does this mean for design?
The wider range means VOOHU WHSM24P02N0 can be used directly in industrial-grade and wide-temperature applications without additional thermal derating. For server rooms, industrial equipment, or outdoor edge nodes, this is a significant advantage.
VOOHU WHSM24P02N0's OCL (120 uH) is lower than Pulse (200 uH). Does this affect 10G Ethernet performance?
The IEEE 802.3 10GBASE-T standard typically requires OCL above 100 uH. VOOHU's 120 uH meets this requirement. Real-world link performance should be validated with the target PHY chip and system circuit.
Is VOOHU WHSM24P02N0 RoHS compliant and environmentally certified?
Yes. VOOHU WHSM24P02N0 is fully RoHS compliant, free of lead, mercury, cadmium, and other restricted substances. It supports lead-free reflow (peak 250°C), compatible with standard SMT production lines.
What is the minimum order quantity (MOQ) and lead time for VOOHU WHSM24P02N0?
VOOHU WHSM24P02N0 is packaged in Tape & Reel at 450 pcs per reel. VOOHU supports sample orders with shipment within 48 hours and delivery within 7 days. For bulk pricing, contact: TEL: +86 400 1048 018, WEB: www.voohuele.com.
