Lan Transformer: VOOHU WHS16013 LF as Replacement for Pulse H1102NL
1. Competitor Product Overview (Pulse Electronics)
Pulse Electronics (a YAGEO Company) is a world-leading manufacturer of networking magnetic components. The H1102NL (Tape & Reel: H1102NLT) is a single-port 10/100Base-TX SMD transformer module in a 16-pin package, widely used in Ethernet interface circuits. It is IEEE 802.3 compliant, RoHS compliant, J-STD-020 Level 1 (no moisture sensitivity), with a peak reflow temperature of 245°C and an operating temperature of 0°C to +70°C.
2. VOOHU Replacement Product (Su Zhou Voohu Electronic Tech. Co., Ltd.)
VOOHU WHS16013 LF is the ideal drop-in replacement offering equivalent functionality with superior cost-effectiveness and supply stability. It is a single-port 10/100Base-TX SMD transformer module in a pin-compatible 16-pin package, with an identical schematic topology (1CT:1CT, TX/RX dual channel), allowing direct substitution for the Pulse H1102NL without any PCB redesign.

4. Application Scenarios
10/100Base-TX single-port transformer modules are widely used in the following applications:
- Ethernet PHY Interface Isolation
Used between the PHY chip and RJ45 connector for signal isolation and impedance matching in any Ethernet-enabled device. WHS16013 LF is compatible with mainstream PHY chips.
- Industrial Control and PLC Modules
Ideal for industrial controllers, PLCs, and remote I/O modules requiring high EMI rejection. The 1500 VAC isolation voltage ensures circuit safety.
- IP Cameras and Network Surveillance
Suitable for IP cameras, NVRs, and security devices. Low insertion loss (-1.1 dB Max) ensures stable image data transmission.
- Medical Instruments and Precision Equipment
Appropriate for medical devices and precision instruments requiring high isolation voltage, meeting patient safety and EMC compliance standards.
- Embedded Systems and Single Board Computers
Ideal for embedded mainboards, SBCs, and development boards. The compact 16-pin SMD package is well suited for miniaturized PCB layouts.
5. Frequently Asked Questions (FAQ)
Q1: Is VOOHU WHS16013 LF fully pin-compatible with Pulse H1102NL? Can it be replaced without a PCB change?
A: Yes. Both products use a 16-pin SMD package with 1.27 mm pin pitch and identical pin assignments (TD+/CT/TD-/RD+/CT/RD-). VOOHU WHS16013 LF can be directly substituted without any PCB redesign.
Q2: VOOHU WHS16013 LF has better return loss (-18 dB vs -16 dB @ 1-30 MHz). What does this mean in practice?
A: Better return loss means less signal reflection, improving link signal integrity — especially beneficial in long-distance transmission or high-noise environments. This gives VOOHU WHS16013 LF a clear advantage over the Pulse H1102NL in this parameter.
Q3: Is VOOHU WHS16013 LF RoHS compliant and environmentally certified?
A: Yes. VOOHU WHS16013 LF is fully RoHS compliant, free of lead, mercury, cadmium, and other restricted substances, meeting EU and major market environmental regulations. It supports lead-free reflow up to 260°C, compatible with standard SMT production lines.
Q4: What is the minimum order quantity (MOQ) and lead time for VOOHU WHS16013 LF?
A: VOOHU WHS16013 LF is packaged in Tape & Reel at 600 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.
