DS90C031TM Equivalent & Substitute Parts

Part Overview

The DS90C031TM is a 4/0 LVDS driver IC manufactured by Texas Instruments in a 16-SOIC surface mount package. This component is classified as not for new designs, indicating it has been superseded in the manufacturer's product line. Finding equivalent or substitute parts is necessary for legacy system maintenance, repair operations, and applications where continued supply of the original part is limited or unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the DS90C031TM is determined by the following critical parameters:

• Protocol compatibility: LVDS
• Driver/receiver configuration: 4/0
• Package type: 16-SOIC surface mount
• Operating temperature range: -40°C ~ 85°C
• Supply voltage range: 4.5V ~ 5.5V
• RoHS3 compliance and MSL rating

Two substitute parts meet these criteria with varying product status and supply chain availability:

1. DS90C031TM/NOPB (Texas Instruments) - Direct equivalent with active product status
2. ADN4665ARZ (Analog Devices Inc.) - Functional equivalent with different supply voltage specification

Parameter Comparison

Engineering Selection Recommendations

DS90C031TM/NOPB is the primary substitute for the DS90C031TM. Both parts are manufactured by Texas Instruments, share identical electrical specifications, package configuration, and compliance certifications. The DS90C031TM/NOPB carries active product status, ensuring continued availability and supply chain support. This part is the direct replacement for legacy applications.

ADN4665ARZ from Analog Devices Inc. is a functional equivalent that maintains LVDS protocol, 4/0 driver configuration, 16-SOIC package, and operating temperature range. However, the supply voltage specification differs: ADN4665ARZ operates at 3V ~ 3.6V versus the 4.5V ~ 5.5V requirement of the original part. This voltage difference requires circuit design verification before implementation. ADN4665ARZ is suitable only for applications where the lower supply voltage is compatible with system requirements.

Both substitute parts maintain RoHS3 compliance and MSL rating 1, meeting environmental and reliability standards equivalent to the original component.

Frequently Asked Questions (FAQ)

Q: Can DS90C031TM/NOPB be used as a direct replacement for DS90C031TM?

A: Yes. Both parts are electrically and mechanically identical. The DS90C031TM/NOPB is the active production variant with the same supply voltage (4.5V ~ 5.5V), operating temperature range (-40°C ~ 85°C), LVDS protocol, 4/0 driver configuration, and 16-SOIC package. No circuit modifications are required.

Q: What is the key difference between DS90C031TM and ADN4665ARZ?

A: The primary difference is supply voltage specification. DS90C031TM operates at 4.5V ~ 5.5V, while ADN4665ARZ operates at 3V ~ 3.6V. Both maintain identical LVDS protocol, 4/0 driver configuration, package type, and operating temperature range. Substitution with ADN4665ARZ requires verification that the system power supply can be adjusted to the 3V ~ 3.6V range.

Q: Are all substitute parts in the same package?

A: Yes. DS90C031TM, DS90C031TM/NOPB, and ADN4665ARZ are all housed in 16-SOIC (0.154", 3.90mm Width) surface mount packages. Pin-to-pin compatibility is maintained across all three parts.

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

A: Yes. All three parts are ROHS3 compliant with MSL rating 1 (Unlimited). Environmental and reliability certifications are equivalent across the original and substitute components.

Q: Which substitute should be selected for new legacy system repairs?

A: DS90C031TM/NOPB is the recommended choice for legacy system repairs. It maintains active product status, identical electrical specifications, and full compatibility with the original DS90C031TM design without requiring circuit modifications.
