PI90LV9637WE LVDS Receiver Equivalent & Substitute Parts

Part Overview

The PI90LV9637WE is a 0/2 LVDS receiver IC manufactured by Diodes Incorporated in an 8-MSOP package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The part operates at 400 Mbps data rate with a 3V to 3.6V supply voltage range and -40°C to 85°C operating temperature specification. Substitute parts maintain functional equivalence through matching protocol, receiver configuration, electrical performance, and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI90LV9637WE is determined by the following critical parameters:

Primary Substitution Criteria:

• Protocol: LVDS
• Type: Receiver
• Number of Drivers/Receivers: 0/2
• Voltage - Supply: 3V ~ 3.6V
• Operating Temperature: -40°C ~ 85°C
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Compatibility Factors:

• Data Rate: 400 Mbps (primary specification) or 150 Mbps (reduced performance variant acceptable)
• Package Type: 8-SOIC or 8-MSOP configurations
• Receiver Hysteresis: 50 mV (where specified)

All substitute parts listed maintain functional equivalence through matching LVDS protocol implementation, identical receiver configuration (0/2), and compatible electrical operating parameters. Package variations between 8-MSOP and 8-SOIC are acceptable substitutes provided PCB layout accommodates the dimensional differences.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Full Specification Match):

SN65LVDS9637BD, SN65LVDS9637BDR, SN65LVDT9637BD, and SN65LVDT9637BDR are direct functional equivalents. All are manufactured by Texas Instruments with active product status, matching 400 Mbps data rate, and identical electrical operating parameters. These parts are available in 8-SOIC packaging, which requires PCB layout verification for pin-to-pin compatibility with the original 8-MSOP footprint. All maintain ROHS3 compliance and MSL 1 rating.

Secondary Substitutes (Reduced Data Rate):

SN65LVDS9637D and SN65LVDS9637DR operate at 150 Mbps data rate, suitable only for applications where the full 400 Mbps specification is not required. These parts are appropriate for legacy system support or reduced-bandwidth implementations.

Alternative Substitute:

FIN1028M (Fairchild Semiconductor) is an active product with matching LVDS protocol and 0/2 receiver configuration. Specific data rate information is not provided in the available parameters; verification against application requirements is necessary before selection.

Procurement Considerations:

All substitute parts carry active product status, ensuring long-term availability and supply chain stability compared to the obsolete PI90LV9637WE. Texas Instruments parts demonstrate the highest inventory levels across multiple packaging options (Tube and Tape & Reel configurations).

Frequently Asked Questions (FAQ)

Q: Can I directly replace PI90LV9637WE with SN65LVDS9637BD without PCB modifications?

A: Functional replacement is possible, but PCB layout verification is required. The PI90LV9637WE uses 8-MSOP packaging (0.118" width), while SN65LVDS9637BD uses 8-SOIC packaging (0.154" width). Pin assignments must be verified against both datasheets to confirm compatibility. Footprint conversion may be necessary.

Q: What is the difference between SN65LVDS9637 and SN65LVDT9637 series?

A: Both series maintain identical electrical specifications for the 9637 receiver configuration. The primary distinction is series designation (LVDS versus LVDT). Both are LVDS protocol receivers with 0/2 configuration and 400 Mbps data rate capability. Selection between series should be based on datasheet pin compatibility and application requirements.

Q: Are the 150 Mbps variants (SN65LVDS9637D/DR) suitable replacements?

A: The 150 Mbps variants are functionally compatible only for applications operating below 150 Mbps. If the original design requires 400 Mbps performance, these parts are not appropriate substitutes. Verify application bandwidth requirements before selection.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in 8-SOIC (0.154", 3.90mm Width) surface mount packages. Packaging variants include Tube and Tape & Reel (TR) configurations for different procurement and assembly workflows. The original 8-MSOP packaging is not available in active substitute products.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original PI90LV9637WE specifications. Compliance documentation is available from respective manufacturers.

Q: Which substitute part has the highest inventory availability?

A: SN65LVDS9637D maintains the highest inventory level at 59,661 pieces. For 400 Mbps applications, SN65LVDS9637BDR offers 5,204 pieces in Tape & Reel packaging, suitable for production volume requirements.
