Lan Transformer:VOOHU WHSG24F01ATG as Replacement for Pulse H5008NL
1. Competitor Product Overview (Pulse Electronics / YAGEO)
Pulse Electronics (a YAGEO company) H5008NL (Tape & Reel: H5008NLT) is a 1000BASE-T quad-channel SMD Ethernet transformer module in a 24-pin package, compliant with IEEE 802.3 and J-STD-020 Level 1 (no moisture sensitivity), RoHS compliant, with a peak reflow temperature of 245°C. It operates over 0°C to +70°C (commercial grade), with a 1CT:1CT (1:1 ±2%) turns ratio and 1500 Vrms input-to-output isolation, designed for Gigabit Ethernet interfaces.
2. VOOHU Replacement Product (Su Zhou Voohu Electronic Tech. Co., Ltd.)
VOOHU WHSG24F01ATG is the ideal drop-in replacement offering equivalent functionality with superior cost-effectiveness and supply stability. It is a 100/1000 BASE-TX quad-channel SMD transformer module in a fully pin-compatible 24-pin package (pinout identical to the H5008NL, with matching 4-channel TCT/TD± and MCT/MX± positions), with the same circuit topology (1CT:1CT × 4 channels) and a wider operating temperature range (-40°C to +85°C) — allowing direct substitution for the Pulse H5008NL with no PCB redesign.

4. Application Scenarios
1000BASE-T (Gigabit Ethernet) quad-channel SMD transformer modules are widely used in:
- Gigabit Ethernet Switches and Routers
Suitable for enterprise and industrial-grade Gigabit switches and routers. Quad-channel integration reduces PCB footprint and eases high-density board layout.
- Server Motherboards and Network Interface Cards (NIC)
Ideal for server motherboards and Gigabit NICs. VOOHU WHSG24F01ATG's wide temperature range (-40°C to +85°C) accommodates data center and industrial server environments.
- Industrial Ethernet and Edge Computing Gateways
Suitable for industrial switches, edge gateways and SCADA systems. The -40°C to +85°C range covers temperature-variable industrial environments; 1500 VAC isolation ensures safety.
- Telecom Infrastructure and Access Equipment
Applicable to fiber/DSL access devices and small-cell backhaul modules; 100/1000 BASE-T dual-speed capability supports high-density integration.
- Surveillance and High-Reliability Industrial Equipment
The wide-temperature characteristic suits security/surveillance, building automation and high-reliability industrial communications requiring strong environmental adaptability.
5. Frequently Asked Questions (FAQ)
Q1: Is VOOHU WHSG24F01ATG fully pin-compatible with Pulse H5008NL? Can it be replaced without a PCB change?
A: Yes. Both use a 24-pin SMD package with ~1.0 mm pin pitch and 10.89 mm pin span, with an identical 4-channel pinout (matching TCT/TD± and MCT/MX± positions) and the same per-channel 1CT:1CT topology. WHSG24F01ATG is a direct drop-in with no PCB redesign; only verify enclosure height clearance (Pulse 5.87 mm vs VOOHU 6.10 mm).
Q2: How do the temperature grades differ?
A: VOOHU WHSG24F01ATG operates over -40°C to +85°C, wider than the Pulse H5008NL's 0°C to +70°C (commercial grade). VOOHU therefore offers greater margin at both low and high temperatures, better suited to industrial, outdoor and temperature-variable applications.
Q3: What is the minimum order quantity (MOQ) and lead time for WHSG24F01ATG?
A: WHSG24F01ATG is packaged in Tape & Reel at 500 pcs per reel (1,000 pcs per inner carton, 5,000 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.
