Engineering Selection Recommendations
All listed substitute parts maintain full electrical and mechanical compatibility with the PI90LV031ALEX. Selection among active alternatives should be based on the following factors:
Product Status: The PI90LV031ALEX is obsolete. All substitute parts listed carry active product status, ensuring long-term availability and continued manufacturer support.
Compliance: All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original part's regulatory standing.
Data Rate Capability: The ADN4665ARUZ, ADN4665ARUZ-REEL7, DS90LV031ATMTC/NOPB, and DS90LV031ATMTCX/NOPB operate at 400 Mbps, matching the original specification. The SN65LVDS391PWR operates at 630 Mbps, providing enhanced performance headroom for applications requiring higher data throughput.
Packaging Format: Choose based on procurement workflow. Tube packaging suits lower-volume applications. Tape & Reel and Cut Tape formats support automated assembly processes. The DS90LV031ATMTCX/NOPB offers the highest inventory availability at 17,740 pieces.
Frequently Asked Questions (FAQ)
Q: Can I use SN65LVDS391PWR as a direct replacement for PI90LV031ALEX?
A: Yes. The SN65LVDS391PWR maintains all critical electrical and mechanical parameters: 4/0 LVDS driver configuration, 16-TSSOP package, 3V to 3.6V supply voltage, and -40°C to 85°C operating temperature. The higher 630 Mbps data rate does not prevent operation in 400 Mbps applications.
Q: What is the difference between ADN4665ARUZ and ADN4665ARUZ-REEL7?
A: Both parts are electrically identical. The difference is packaging format: ADN4665ARUZ is supplied in Tube packaging, while ADN4665ARUZ-REEL7 is supplied in Tape & Reel format. Select based on assembly and procurement requirements.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All substitute parts listed carry ROHS3 compliance certification, matching the original PI90LV031ALEX specification.
Q: Can I mix different substitute parts in the same production run?
A: Yes. All substitute parts are electrically and mechanically equivalent. Mixing different manufacturers or packaging formats does not affect circuit performance, though procurement and inventory management practices may influence this decision.
Q: Which substitute part has the best availability?
A: The DS90LV031ATMTCX/NOPB from Texas Instruments offers the highest inventory level at 17,740 pieces in stock.
