AVAGO Series Selection Guidance for Different Projects
1. New Energy Inverter & Industrial Frequency Converter
Must select HCPL-3120 IGBT drive optocoupler. Strong anti-interference performance to suppress high-frequency switching noise, the most widely used AVAGO model in energy storage and photovoltaic inverter projects. June inventory is stable to support continuous mass production.
2. Medical Equipment Precision Isolation Power
HCNR200 linear optocoupler is irreplaceable for low-distortion analog isolation. Strict medical-grade reliability standards, no signal distortion under weak voltage sampling conditions.
3. AI Server & Industrial Computer Backplane
PEX8764 PCIe Gen3 switch chip expands high-speed data transmission lanes. Official supply is tight in Q2 2026; LXB holds verified original BGA industrial-grade stock for server repair and new board trial production.
4. Low-Cost Consumer & Small Industrial Control
HCPL-817 universal optocoupler with ultra-stable price and sufficient global inventory, suitable for low-voltage power isolation of household equipment, small sensors and charging modules.
Replacement & Cross Reference Suggestions
- HCPL-0661 can replace HCPL-2631 for high-speed digital isolation upgrade;
- HCNR200 linear optocoupler has no direct pin-compatible substitute, stock locking is recommended for mass medical projects;
- PEX8748 can downgrade replace PEX8764 if fewer PCIe lanes are required.
LXB Semicon AVAGO Supply Advantages
- Complete AVAGO optocoupler full series spot stock covering DIP and SMD packages;
- Original Broadcom-marked communication BGA chips with full quality inspection;
- Support mixed batch order of optocoupler small samples and large communication IC bulk goods;
- Professional technical support for optocoupler isolation circuit design matching.
SSS
- Why are AVAGO high-speed optocouplers hard to source in June 2026?
Global new energy inverter demand surges, wafer and packaging capacity is saturated, original factory delivery cycle exceeds 6 months.
- What is the difference between HCPL-3120 and ordinary optocouplers?
Built-in large-current drive circuit, directly drive high-power IGBT power tubes without external drive amplifiers.
- Are AVAGO chips compatible with old PCB layouts?
All stocked models maintain unified pin definitions consistent with original datasheets, direct drop-in replacement without PCB redesign.
