I would appreciate if anyone could provide me the alternative part number for MRF101AN.?? And idea on availability for the same for next few years.
thank you!
**MRF101AN Status & Alternatives**
### Current Status
**MRF101AN** (NXP) is now in **End-of-Life / Last Time Buy**.
| Item | Details |
|----------------------------|--------------------------------------|
| **Lifecycle** | End of Life (EOL) / Last Time Buy |
| **Last Time Buy (LTB)** | **30 September 2026** |
| **Last Time Delivery (LTD)** | **30 September 2027** |
| **Reason** | NXP is ramping down the Radio Power product line |
After September 2026 you will no longer be able to place new orders with NXP. Remaining stock will be allocated on a first-come, first-served basis until the final shipment date in 2027.
---
### Closest Alternatives
| Part Number | Manufacturer | Key Differences | Compatibility | Recommendation |
|------------------|--------------|------------------------------------------|--------------------------------|--------------|
| **MRF101BN** | NXP | Mirror pin-out version of MRF101AN | Same package (TO-220), electrical performance almost identical | Best short-term option if pin-out can be flipped |
| **MRF300AN / MRF300BN** | NXP | 300 W version (higher power) | Different package (TO-247) | Only if you need higher power and can redesign |
| No official drop-in | — | NXP has **not** released a pin-compatible successor | — | — |
**Note**: NXP has not published an official pin-to-pin replacement for the MRF101AN. The **MRF101BN** is the closest device (same electrical characteristics, mirrored pin-out).
---
### Third-party / Competitive Alternatives (not pin-compatible)
These require board redesign but are still in active production:
- Ampleon BLF188XR / BLF189XRG (higher power, different package)
- STMicroelectronics STAC2932B or similar LDMOS devices
- Other 50 V LDMOS devices in the 100 W class from Infineon or MACOM (need matching for frequency and power)
---
### Availability Outlook (Next Few Years)
| Period | Availability Expectation |
|---------------------|----------------------------------------------|
| Now – Sep 2026 | Still orderable (Last Time Buy window) |
| Oct 2026 – Sep 2027 | Only remaining stock / residual shipments |
| After Sep 2027 | No new supply from NXP |
**Recommendation**:
1. Place a **Last Time Buy** as soon as possible if you still need this exact part.
2. Start evaluating **MRF101BN** (if pin-out change is acceptable) or begin a redesign to a currently active 50 V LDMOS device.
3. Contact : [email protected].
Would you like me to help compare specific electrical parameters of MRF101AN vs MRF101BN, or suggest possible redesign candidates based on your frequency and power requirements?
