Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI90LV028AWEX is determined by strict alignment of the following critical parameters:

• Receiver Configuration: 0/2 (two receivers, no drivers)
• Protocol Standard: LVDS (Low-Voltage Differential Signaling)
• Data Rate: 400 Mbps minimum
• Supply Voltage Range: 3V to 3.6V
• Package Type: 8-SOIC surface mount
• Operating Temperature Range: -40°C to 85°C minimum
• Compliance: ROHS3 and REACH requirements

The SN65LVDS34DR from Texas Instruments meets all specified parameters and qualifies as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The SN65LVDS34DR is the qualified substitute for the PI90LV028AWEX based on the following factors:

Compliance & Availability: The SN65LVDS34DR maintains ROHS3 and REACH compliance identical to the original part. As an active product from Texas Instruments with 5120 units in stock, it provides assured long-term availability compared to the obsolete PI90LV028AWEX.

Electrical & Mechanical Compatibility: All critical electrical parameters—receiver configuration, LVDS protocol, 400 Mbps data rate, 3V to 3.6V supply voltage, and -40°C to 85°C operating temperature—are identical. The 8-SOIC package dimensions and surface mount characteristics ensure direct PCB compatibility without layout modifications.

Functional Equivalence: Both devices implement identical receiver functionality with matching pin configurations and electrical specifications, enabling direct substitution in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the SN65LVDS34DR replace the PI90LV028AWEX in existing designs?

A: Yes. The SN65LVDS34DR is functionally equivalent across all specified electrical and mechanical parameters. No circuit modifications or PCB layout changes are required for direct substitution.

Q: Are there differences in receiver hysteresis between these parts?

A: The SN65LVDS34DR specifies a receiver hysteresis of 50 mV. This parameter was not provided for the PI90LV028AWEX in the available documentation. Verify hysteresis requirements against your system specifications before implementation.

Q: Why is the PI90LV028AWEX listed as obsolete?

A: The PI90LV028AWEX has reached end-of-life status with Diodes Incorporated. The SN65LVDS34DR from Texas Instruments provides equivalent functionality with active product support and ongoing availability.

Q: Are the packages identical?

A: Yes. Both devices use the 8-SOIC package with 0.154" width (3.90mm). Pin-to-pin compatibility is confirmed, allowing direct PCB footprint reuse.

Q: What are the compliance certifications for the substitute part?

A: The SN65LVDS34DR is ROHS3 compliant and REACH unaffected, matching the compliance profile of the original PI90LV028AWEX.
