AU ADP releases PCBA IC engineering change (EC) for G238HAN01.1 model
AU Optronics ADP has released an Engineering Change (EC) for PCBA IC for G238HAN01.1 model. Due to the upcoming discontinuation of TCON IC (12303 K07) and PWM IC (P201-1F), in order to ensure stable supply, PIN-PIN compatibility has been replaced with a new type of IC, and the part number has been changed from 97.23G01.100 to 97.23G01.101. The PCBA layout, electrical performance, and specifications remain completely unchanged, and will be executed according to the schedule of sampling/validation in March 2026 and official switch on June 1.
Mind map:
· Detailed Summary
1. Background and purpose of change
· Due to the upcoming EOL (discontinuation) of TCON IC (12303 K07) and PWM IC (P201 1F).
· To ensure continuous and stable supply, ADP has initiated a PCBA IC replacement engineering change (EC).
2.Product and part number changes
Model | Part number before change | Change the part number |
G238HAN01.1 | 97.23G01.100 | 97.23G01.101 |
3. Specific EC content
TCON IC: Replace 12303 K07 with 12303 Z09
PWM IC: Replace P201-1F with P210-10
Key explanation:
The new IC is PIN PIN compatible, and the PCBA layout remains unchanged
The electrical functions and specifications of the panel are completely consistent
4. Verification and Execution Schedule
3/M: Complete sample production
3/E: Complete RA reliability verification
6/1: EC officially switches to running volume
Key questions and answers
1.What is the core reason for this EC?
Answer: The core reason is that the TCON IC (12303 K07) and PWM IC (P201-1F) chips are about to be discontinued and replaced to ensure stable panel supply.
2.Does the change have any impact on product performance and structure?
Answer: No impact. The new IC is PIN-PIN compatible, the PCBA layout remains unchanged, and the panel electrical functions and specifications remain completely consistent.
3.What is the timeline for the execution of this EC?
Answer: Sampling will be conducted in March, validation will be completed in March, and production will officially switch on June 1st, with a smooth transition as planned.
