Part Number: SN65DP149
Other Parts Discussed in Thread: TDP142, TDP2004, TDP0604
Hi TI Team.
We have been using this part no :SN65DP141RLJR (link: https://www.digikey.in/en/products/detail/texas-instruments/SN65DP141RLJR/5973303)for Display port interface(Video Redriver). But the part is obsolete now. we request you to provide exact alternate for this part ensuring same footprint, functionalities and pinouts
**
Answer: No exact pin-to-pin / footprint / functionality replacement exists.**
The **SN65DP141RLJR** (DisplayPort 1.4 Linear Redriver) has been discontinued by Texas Instruments. According to TI’s official responses in their E2E forum and distributor notifications, the entire SN65DP141 family is going EOL.
### TI Recommended Alternatives
TI has suggested the following parts as functional replacements:
| Part Number | Max Speed | Type | Pin-to-Pin Compatible? | Key Differences | Recommendation |
|-------------------|---------------|-------------------|------------------------|------------------|----------------|
| **TDP142** | DP 1.4 (8.1 Gbps) | Linear Redriver | **No** | Similar functionality, different package/pinout | **Best functional match** for your current design |
| **TDP2004** | DP 2.1 (20 Gbps)| Linear Redriver | **No** | Newer generation, higher speed support | Good for future-proofing |
| TDP0604 | DP 1.4 + HDMI | Redriver + Level Shifter | No | Can handle DP++ to HDMI conversion | Only if you need HDMI support |
**Important**: None of these are **drop-in replacements**. They have different pinouts and packages, so a PCB layout change will be required.
### Summary of Differences
| Feature | SN65DP141 (Obsolete) | TDP142 (Recommended) | TDP2004 |
|---------------------------|---------------------------|-------------------------------|--------------------------|
| **DisplayPort Version** | DP 1.4 (HBR3) | DP 1.4 (HBR3) | DP 2.1 (UHBR20) |
| **Data Rate** | Up to 8.1 Gbps | Up to 8.1 Gbps | Up to 20 Gbps |
| **Type** | Linear Redriver | Linear Redriver | Linear Redriver |
| **Pin-to-Pin** | - | No | No |
| **Package** | 38-WQFN (RLJ) | Different | Different |
| **EQ / Pre-emphasis** | Configurable | Configurable | More advanced |
| **Power Consumption** | Low | Similar | Slightly higher |
| **Status** | Obsolete | Active | Active |
### Recommendations
1. **Best Immediate Option**:
Switch to **TDP142**. It is the closest functional replacement for DisplayPort 1.4 redriver applications.
2. **Future-Proof Option**:
Use **TDP2004** if you want to support higher-speed DisplayPort 2.1 in future designs.
3. **Next Steps**:
- Download the datasheets for **TDP142** and **TDP2004** and compare pinouts with your current layout.
- Contact your TI FAE / local sales for:
- Official recommendation
- Any possible last-time-buy (LTB) quantity for SN65DP141RLJR
- Evaluation boards/samples of TDP142 or TDP2004
- Consider whether you can accept a small PCB respin (most customers do this when moving from SN65DP141).
Would you like me to:
- Compare the pinouts between SN65DP141 and TDP142?
- Suggest possible third-party alternatives (e.g., from Diodes Inc. / Parade)?
- Help evaluate the TDP142 / TDP2004 based on your specific DisplayPort version and trace length?
