LAN Transformer: VOOHU WHS16013LF as Replacement for Pulse H1102NL
1. Competitor Product Overview (Pulse Electronics)
Pulse Electronics (a YAGEO Company) is a 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 (Suzhou VOOHU Electronic Technology Co., Ltd.)
VOOHU WHS16013 LF is a replacement candidate for the Pulse H1102NL, with comparable core specifications. 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). Verify with samples before production.

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
Suitable for Ethernet interfaces in medical devices and precision instruments (1500 VAC isolation); check the isolation your safety standard requires.
- 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 pin-compatible with Pulse H1102NL?
A: 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 is a replacement candidate; verify with samples before production.
