DS90C031TM/NOPB Equivalent & Substitute Parts

Part Overview

The DS90C031TM/NOPB is a 4/0 Driver interface IC manufactured by Texas Instruments, designed for LVDS (Low-Voltage Differential Signaling) applications. This Surface Mount device operates within a 4.5V to 5.5V supply voltage range and maintains performance across the -40°C to 85°C industrial temperature range. The part is currently Active in product status with 3236 units available in inventory. Equivalent and substitute parts are identified when design requirements shift, supply constraints occur, or alternative protocol support becomes necessary while maintaining compatible electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DS90C031TM/NOPB are identified based on strict alignment of the following critical parameters:

Mechanical Compatibility:

• Package / Case: 16-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Supplier Device Package: 16-SOIC

Electrical Compatibility:

• Number of Drivers/Receivers: 4/0 configuration
• Operating Temperature Range: -40°C ~ 85°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Protocol Considerations: Substitutes may operate under different communication protocols (LVDS, RS422, RS485) provided all mechanical and core electrical parameters remain compatible. Protocol differences do not preclude substitution when the application architecture supports the alternative protocol.

Supply Voltage: Substitute parts must operate within overlapping or equivalent voltage supply ranges to ensure direct replacement capability.

Parameter Comparison

Engineering Selection Recommendations

DS26C31TM/NOPB (Texas Instruments): This substitute maintains identical mechanical packaging, supply voltage range, and operating temperature specifications. The primary difference is protocol support: RS422 and RS485 instead of LVDS. Both parts are Active in product status and ROHS3 Compliant. Selection of this substitute is appropriate when the application architecture supports RS422/RS485 protocol operation and identical supply voltage requirements are met.

ADN4665ARZ (Analog Devices Inc.): This substitute maintains identical mechanical packaging, LVDS protocol, and operating temperature range. The supply voltage range differs: 3V to 3.6V versus the main part's 4.5V to 5.5V. Both parts are Active in product status and ROHS3 Compliant. Selection of this substitute requires verification that the application power supply can operate within the 3V to 3.6V range. The ADN4665ARZ supports 400Mbps data rate operation.

All substitute parts maintain Active product status, ensuring continued availability and manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can DS26C31TM/NOPB replace DS90C031TM/NOPB in any application?

A: DS26C31TM/NOPB is mechanically and electrically compatible in terms of package, pin count, supply voltage, and operating temperature. The primary consideration is protocol compatibility: DS26C31TM/NOPB operates under RS422/RS485 protocols while DS90C031TM/NOPB operates under LVDS. Substitution is valid only when the application architecture supports RS422/RS485 protocol operation.

Q: What is the key limitation of ADN4665ARZ as a substitute?

A: ADN4665ARZ operates within a 3V to 3.6V supply voltage range, whereas DS90C031TM/NOPB requires 4.5V to 5.5V. Direct substitution requires the application power supply to operate within the lower voltage range. All other mechanical and thermal specifications are compatible.

Q: Are all three parts pin-compatible?

A: All three parts use the 16-SOIC package with identical physical dimensions (0.154", 3.90mm Width). Pin compatibility for direct PCB replacement is confirmed based on the provided specifications.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. DS90C031TM/NOPB, DS26C31TM/NOPB, and ADN4665ARZ are all ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited) and maintain Active product status.

Q: What is the data rate specification for ADN4665ARZ?

A: ADN4665ARZ supports 400Mbps data rate operation. Data rate specifications are not provided for DS90C031TM/NOPB or DS26C31TM/NOPB in the available parameters.
