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) H5004NL (Tape & Reel: H5004NLT) is a 1000BASE-T single-port (4-channel integrated) SMD magnetics module in a 24-pin package, designed to support 1:1 turns-ratio Gigabit transceivers, compliant with IEEE 802.3, RoHS compliant, MSL 4, with a peak reflow temperature of 245°C. It operates over 0°C to +70°C (commercial grade), with 1500 Vrms input-to-output isolation, and ships in Tape & Reel at 300 pcs per reel.
#2. VOOHU Replacement Product (Su Zhou Voohu Electronic Tech. Co., Ltd.)
VOOHU WHSG24701G is the ideal drop-in replacement offering equivalent functionality with superior cost-effectiveness and supply stability. It is a 100/1000 BASE-T single-port (4-channel integrated) SMD transformer module in a fully pin-compatible 24-pin package (pinout identical to the H5004NL, with matching 4-channel TCT/TD± and MCT/MX± positions), with the same circuit topology (1CT:1CT × 4 channels), the same 0°C to +70°C operating range, and nearly identical package dimensions and footprint — allowing direct substitution for the Pulse H5004NL with no PCB redesign.
#3. Key Parameter Comparison
The table below maps the Pulse datasheet (HC500.T) / product-page parameters to the corresponding VOOHU WHSG24701G specifications.
#4. Application Scenarios
1000BASE-T (Gigabit Ethernet) single-port quad-channel SMD magnetics modules are widely used in:
- 1.Gigabit Ethernet Switches and Routers
Suitable for enterprise-grade Gigabit switches and routers. Single-port quad-channel integration reduces PCB footprint and eases high-density board layout.
- 1.Server Motherboards and Network Interface Cards (NIC)
Ideal for server motherboards and Gigabit NICs; pin and dimensional compatibility allows direct substitution of the Pulse design.
- 1.Networking and Access Equipment
Suitable for routers, fiber/DSL access devices and small-cell backhaul modules; supports 100/1000 BASE-T dual-speed auto-negotiation.
- 1.Industrial Ethernet and Edge Computing Gateways
Suitable for industrial switches and edge gateways; 1500 V isolation ensures safety. For a wider range (-40°C to +85°C), VOOHU also offers wide-temperature series such as the WHSG24F01ATG.
- 1.Consumer Electronics and Surveillance Equipment
Suitable for set-top boxes, IP network cameras, NVR/DVR and consumer/security electronics with a Gigabit Ethernet port.
#5. Frequently Asked Questions (FAQ)
Is VOOHU WHSG24701G fully pin-compatible with Pulse H5004NL? Can it be replaced without a PCB change?
Yes. Both use a 24-pin SMD package with 1.27 mm pin pitch and 13.97 mm pin span, with an identical 4-channel pinout (matching TCT/TD± and MCT/MX± positions), the same per-channel 1CT:1CT topology, and nearly identical dimensions (17.5 × 12.2 mm). WHSG24701G is a direct drop-in with no PCB redesign; only verify enclosure height clearance (Pulse 5.72 mm vs VOOHU 6.00 mm).
Do both parts share the same temperature grade?
Yes. Both operate over 0°C to +70°C (commercial grade), suitable for standard indoor networking and consumer/industrial Ethernet equipment. If a wider range is required (-40°C to +85°C), VOOHU also offers wide-temperature series such as the WHSG24F01ATG.
What is the minimum order quantity (MOQ) and lead time for WHSG24701G?
WHSG24701G is packaged in Tape & Reel at 350 pcs per reel (700 pcs per inner carton, 3,500 pcs per export carton). VOOHU supports sample orders shipped within 48 hours and delivered within 7 days. For bulk pricing, contact: TEL: +86 400 1048 018, WEB: www.voohuele.com.
