Lan Transformer: VOOHU WHS40005T G as Replacement for Pulse HX1234NLT

1. Competitor Product Overview (Pulse Electronics)

Pulse Electronics (a YAGEO Company) is a world-leading manufacturer of networking magnetic components. The HX1234NL (Tape & Reel: HX1234NLT) is a 10/100Base-TX transformer module designed for Auto MDI/MDIX applications, featuring symmetrical transmit/receive channels. It is approved for use with Broadcom BCM5226 and Level One LXT9784, compliant with IEEE 802.3 and RoHS standards (peak reflow 245°C).

2. VOOHU Replacement Product (Su Zhou Voohu Electronic Tech. Co., Ltd.)

VOOHU WHS40005T G is the ideal drop-in replacement that meets equivalent functional requirements while offering superior cost-effectiveness and supply stability. It is a 10/100Base-TX SMD transformer module in a pin-compatible 40-pin package with an identical schematic, allowing direct substitution for the Pulse HX1234NLT without PCB redesign.

3. Key Parameter Comparison

The table below compares the core parameters of both products.

4. Application Scenarios

10/100Base-TX transformer modules are widely used in the following applications:

1. Industrial Ethernet Equipment

Suitable for industrial controllers, PLCs, and distributed I/O modules requiring stable communication under harsh conditions (wide temperature range, high EMI). The WHS40005T G -40°C to +85°C range meets industrial-grade requirements.

2. Network Switches and Routers

Ideal for enterprise and consumer Ethernet switches and home routers requiring high-density multi-port (4-port) magnetic integration.

3. IP Cameras and Network Surveillance

Suited for security equipment requiring long-distance, stable transmission. The WHS40005T G offers lower insertion loss (-1.1 dB vs -1.4 dB), delivering better signal integrity.

4. Medical Electronics and Instruments

Appropriate for medical devices and precision instruments requiring high isolation voltage (1500 VAC), meeting patient safety isolation and anti-interference requirements.

5. Smart Home and IoT Gateways

Suitable for smart home hubs and IoT edge gateways requiring low power, compact SMD packaging for high-density PCB designs.

5. Frequently Asked Questions (FAQ)

Q1: Is VOOHU WHS40005T G fully pin-compatible with Pulse HX1234NLT? Can it be replaced without a PCB change?

A: Yes. Both products use a 40-pin SMD package with identical pin definitions and pad layout (1.27 mm pitch). VOOHU WHS40005T G can be directly substituted without any PCB redesign.

Q2: Does this transformer module support PoE (Power over Ethernet)?

A: No. Both Pulse HX1234NLT and VOOHU WHS40005T G are pure network transformer modules without PoE circuitry. If PoE is required, a dedicated PoE PD/PSE controller and associated circuitry must be added at the system level.

Q3: What is the minimum order quantity (MOQ) and lead time for VOOHU WHS40005T G?

A: VOOHU WHS40005T G is packaged in Tape & Reel at 400 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.
