Compiled from both manufacturers' published datasheets. Verify with samples and the PCB footprint before production.
#1. Competitor Product Overview (Bourns)
The Bourns SM91074AL is a 10/100 Base-T single-port low-profile SMD Ethernet transformer module in a 16-pin package, compliant with IEEE 802.3u (100 Base-T), AEC-Q200 automotive-grade qualified, RoHS compliant and halogen free. It operates over -40°C to +125°C, is rated MSL 1, with a peak reflow temperature of 245-250°C, and ships in Tape & Reel at 600 pcs per reel. It is widely used in industrial and automotive Fast Ethernet interfaces.
#2. VOOHU Replacement Product (Su Zhou Voohu Electronic Tech. Co., Ltd.)
VOOHU WHS16002GA is the ideal drop-in replacement offering equivalent functionality with superior cost-effectiveness and supply stability. It is a 10/100 BASE-TX single-port low-profile SMD transformer module in a fully pin-compatible 16-pin package (pinout identical to the SM91074AL), with the same circuit topology (1CT:1CT dual winding), the same -40°C to +125°C operating range, AEC-Q200 tested, IEEE 802.3 compliant and RoHS compliant — allowing direct substitution for the Bourns SM91074AL with no PCB redesign.
#3. Key Parameter Comparison
The table below maps the Bourns datasheet parameters to the corresponding VOOHU WHS16002GA specifications.
Notes:
- Turns-ratio tolerance is ±2% (Bourns) vs ±5% (VOOHU); both are adequate for 10/100BASE-T — bench validation recommended where ratio accuracy is critical.
② Both parts share identical package dimensions, pinout and circuit topology, are AEC-Q200 automotive-grade, and operate over -40°C to +125°C, enabling true pin-for-pin replacement.
③ Crosstalk and CMR specifications are identical.
#4. Application Scenarios
10/100 BASE-T (Fast Ethernet) single-port low-profile transformer modules are widely used in:
- 1.Industrial Ethernet Switches and Gateways
Suitable for industrial Ethernet switches, edge gateways, SCADA and fieldbus equipment. The -40°C to +125°C range covers harsh factory environments; 1500 VAC isolation ensures safety.
- 1.Automotive Ethernet and Automotive Electronics
Both parts are AEC-Q200 automotive-grade, suitable for 10/100 Ethernet interfaces in automotive gateways, body controllers, infotainment and ADAS domain controllers.
- 1.Embedded and IoT Devices
The low-profile 16-pin package enables high-density board integration, ideal for industrial controllers, PLCs, IoT gateways and smart meters where space and cost matter.
- 1.Networking and Access Equipment
Suitable for routers, switches, IP cameras, POS terminals and network interface cards (NIC) requiring 10/100 Ethernet PHY isolation.
- 1.High-Reliability and Surveillance Systems
Wide-temperature, automotive-grade reliability makes it suitable for security/surveillance, building automation, medical and high-reliability industrial communications.
#5. Frequently Asked Questions (FAQ)
Is VOOHU WHS16002GA fully pin-compatible with Bourns SM91074AL? Can it be replaced without a PCB change?
Yes. Both use a 16-pin low-profile SMD package with 1.27 mm pitch and an identical pinout (TD+/TCT/TD-, RD+/RCT/RD-, TX±/RX± and CMT center-tap positions match) and the same 1CT:1CT dual-winding topology. WHS16002GA is a direct drop-in with no PCB redesign.
Is WHS16002GA an automotive-grade part?
Yes. WHS16002GA is AEC-Q200 tested and rated -40°C to +125°C — the same automotive-grade, wide-temperature class as the Bourns SM91074AL — suitable for automotive electronics and high-reliability industrial applications.
