Engineering Selection Recommendations

Primary Substitutes (Active Status, Full Compliance)

ADN4666ARUZ and ADN4666ARUZ-REEL7 from Analog Devices Inc. are direct functional equivalents with active product status. Both maintain identical electrical and mechanical specifications. The ADN4666ARUZ-REEL7 variant offers tape and reel packaging for high-volume production environments, while ADN4666ARUZ is supplied in tube packaging. Both are ROHS3 compliant with MSL Level 1 rating.

Secondary Substitutes (Active Status)

DS90LV032ATMTC/NOPB from National Semiconductor provides functional equivalence with active product status. RoHS and MSL compliance information is not specified for this part.

SN65LVDT348PWR from Texas Instruments operates at 560 Mbps, exceeding the 400 Mbps requirement of the original part. This part is active, ROHS3 compliant, and MSL Level 1 rated. The higher data rate capability provides additional performance margin.

All substitute parts are surface mount 16-TSSOP packages with identical mechanical dimensions and are suitable for direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can ADN4666ARUZ replace PI90LV032ALEX directly?

A: Yes. Both parts are 0/4 LVDS receivers in 16-TSSOP packages with identical electrical specifications (3V to 3.6V supply, -40°C to 85°C operating range, 400 Mbps data rate). Pin-to-pin compatibility and functional equivalence are established.

Q: What is the difference between ADN4666ARUZ and ADN4666ARUZ-REEL7?

A: Both are identical Analog Devices parts with the same electrical and mechanical specifications. The difference is packaging: ADN4666ARUZ is supplied in tube packaging, while ADN4666ARUZ-REEL7 is supplied in tape and reel format. Selection depends on production volume and assembly line requirements.

Q: Why does SN65LVDT348PWR have a higher data rate (560 Mbps vs 400 Mbps)?

A: SN65LVDT348PWR is specified for 560 Mbps operation, which exceeds the PI90LV032ALEX requirement of 400 Mbps. This higher specification does not prevent substitution; the part operates within the required 400 Mbps bandwidth and maintains all other electrical and mechanical compatibility parameters.

Q: Are all substitute parts ROHS3 compliant?

A: ADN4666ARUZ, ADN4666ARUZ-REEL7, and SN65LVDT348PWR are confirmed ROHS3 compliant. DS90LV032ATMTC/NOPB does not specify RoHS compliance in the provided data.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All substitute parts use the 16-TSSOP package with identical 0.173" width and 4.40mm dimensions. PCB footprints and land patterns are mechanically compatible. No layout modifications are required for substitution.

Q: What is the MSL rating for these parts?

A: ADN4666ARUZ, ADN4666ARUZ-REEL7, and SN65LVDT348PWR are all MSL Level 1 (Unlimited), matching the PI90LV032ALEX specification. DS90LV032ATMTC/NOPB does not specify MSL rating in the provided data.
