Substitute Part Grouping Explanation

Substitution for the PI90LV031AWEX is determined by the following critical parameters:

Primary Substitution Criteria:

Protocol: LVDS
Number of Drivers/Receivers: 4/0
Package / Case: 16-SOIC (0.154", 3.90mm Width)
Mounting Type: Surface Mount
Operating Temperature: -40°C ~ 85°C
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level: 1 (Unlimited)

Secondary Consideration:

Voltage - Supply: 3V ~ 3.6V (primary specification) or 4.5V ~ 5.5V (alternative voltage domain)
Data Rate: 400Mbps (primary specification) or unspecified (alternative)

Substitute parts are grouped into two categories based on voltage supply compatibility. Direct substitutes maintain the 3V ~ 3.6V supply voltage specification. Alternative substitutes operate at 4.5V ~ 5.5V and require voltage domain verification during integration.

Engineering Selection Recommendations

Direct Substitutes (Recommended for Pin-Compatible Replacement):

ADN4665ARZ and SN65LVDS31DR are direct functional equivalents to the PI90LV031AWEX. Both parts maintain identical electrical specifications including 3V ~ 3.6V supply voltage, 400Mbps data rate, and 4/0 driver/receiver configuration. Both are active products with ROHS3 compliance and MSL 1 rating. ADN4665ARZ is supplied in tube packaging, while SN65LVDS31DR is available in cut tape and digi-reel formats.

Manufacturer-Recommended Substitute (Automotive Grade):

ADN4667WARZ-REEL7 is designated as a manufacturer-recommended substitute with automotive-grade qualification. This part maintains all electrical and mechanical compatibility with the PI90LV031AWEX while offering enhanced reliability for automotive applications. It is supplied in tape and reel packaging.

Alternative Voltage Domain Substitutes:

DS90C031BTM/NOPB, DS90C031BTMX/NOPB, DS90C031TM/NOPB, and DS90C031TMX/NOPB operate at 4.5V ~ 5.5V supply voltage. These parts are suitable only for applications where the higher voltage domain is compatible with system design. All four variants maintain the 4/0 LVDS driver configuration and 16-SOIC package. Selection among these variants depends on packaging preference (tube versus cut tape) and inventory availability.

All substitute parts are active products with ROHS3 compliance and MSL 1 moisture sensitivity rating, ensuring long-term supply availability and regulatory compliance.
