N104STN01.0 can be compatible as a replacement for A104SN03 V1
Date:2025-02-26
AUO 10.4-inch A104SN03 V1 is about to be discontinued, N104STN01.0 can be compatible as a replacement for A104SN03 V1.
1、 Key Notice: A104SN03 V1 Production Suspension Confirmation
AU Optronics (AUO) recently released a product lifecycle announcement, stating that the 10.4-inch industrial LCD screen A104SN03 V1 (model name: AUO A104SN03 V.1) will be completely discontinued in Q2 2024. As a classic configuration for industrial HMI, medical equipment, and POS terminals, the delisting of this model will have the following impacts on related industries：
1. Supply chain risk: Orders cannot be added after Q1 2024, and inventory levels continue to decline.
2. Rising maintenance costs: The price of second-hand market circulating screens is expected to increase by 30% -50%.
3. Design iteration pressure: Equipment that has already adopted this model needs to initiate alternative solution verification.
2、 Official recommended alternative model: N104STN01.0 Technical parameter comparison
After confirmation with the AU technical team, N104STN01.0 (new model code: AUO N104STN01.0) is a 100% compatible alternative to A104SN03 V1. The following is a comparison table of key parameters:
Parameter item | A104SN03 V1 | N104STN01.0 | Compatibility Description |
Screen Size | 10.4inch | 10.4inch | Consistent physical dimensions, no need for structural modifications |
Number of Pixel | 800*60（SVGA） | 800*600（SVGA） | The signal interface is fully compatible |
Luminance | 400 cd/m² (Typ.) | 400 cd/m² (Typ.) | Backlight adaptation to the original system |
Contrast Ratio | 500:1 (Typ.) | 900:1 (Typ.) | Image quality prompt, no hardware modification required |
Signal Interface | TTL (1 ch, 6/8-bit) | RGB (1 ch, 6/8-bit) | Same pins, replace directly |
OP Temperature | -10 ~ 60 °C | -10 ~ 60 °C | Same adaptability to work environment |
Typical power consumption | 3.0W | 2.72W | Energy saving optimization to reduce system heating |
3、 Alternative Implementation Operation Guide
Scenario 1: Maintenance and replacement of existing equipment
1. Plug and play solution:
Directly replace the old screen without modifying the driver board or firmware
Pay attention to the difference in backlight brightness: It is recommended to lower the brightness value to the original screen level through the OSD menu or PWM signal (default value of 90% ≈ 400 cd/m ²)
2. Inventory management suggestions:
Prioritize the procurement of N104STN01.0 as spare parts, conduct early testing, and complete the transition.
Scenario 2: New device development and selection
1. Design optimization direction: Utilize the wide temperature characteristics of N104STN01.0 (starting at -30 ℃) to expand equipment application scenarios (such as outdoor gas stations and cold storage scenarios) Suggest reserving 10% brightness adjustment redundancy in the driver circuit
2. Authentication adaptability: The new model has passed certifications such as ISO 13407 (ergonomics) and IEC 60601-1 (medical), and can directly use the original equipment certification documents
4、 Alternative model procurement and technical support
1. Supply guarantee:
N104STN01.0 has entered the long-term supply plan (LTS) of AU, ensuring stable supply for at least 5 years
Current delivery time: Standard products take 4-6 weeks, urgent orders can be shortened to 4 weeks (required ≥ 500pcs)
2. Technical support:
Provide free sample testing kit (including adapter board and driver configuration file)

5、 Frequently Asked Questions (FAQ)
Q1： Are there any other alternative models available?
·If higher resolution is required, evaluate the AU T104XVN01.0 (1024 × 768, requiring modification of the driver board)
Q2： Can old model inventory be mixed with new screens?
·Mixing is allowed, but attention should be paid to brightness consistency. It is recommended to calibrate it uniformly through software
Q3： Is it necessary to conduct EMC testing again after replacement?
·No need for full retesting, only need to submit a model change statement to the certification body
Immediate action suggestion:
Please submit your purchase intention for N104STN01.0 before December 31, 2024.
