PI90LV047ALEX Equivalent & Substitute Parts

Part Overview

The PI90LV047ALEX is a 4/0 LVDS driver interface IC manufactured by Diodes Incorporated in a 16-TSSOP surface mount package. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and design continuity. The part operates at 3V to 3.6V supply voltage with a 400Mbps data rate, supporting LVDS protocol applications requiring low-voltage differential signaling.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PI90LV047ALEX is determined by strict equivalence across the following critical parameters:

• Protocol Compatibility: LVDS driver functionality
• Driver/Receiver Configuration: 4/0 (4 drivers, 0 receivers)
• Data Rate: 400Mbps minimum
• Supply Voltage Range: 3V ~ 3.6V
• Package Type: 16-TSSOP form factor
• Electrical Characteristics: Operating temperature range -40°C ~ 85°C
• Compliance Standards: ROHS3 compliance and MSL rating

The identified substitute parts SN65LVDS047PW and SN65LVDS047PWR, both manufactured by Texas Instruments, meet all specified electrical and mechanical parameters. Both parts are active products with current manufacturing status, distinguishing them from the obsolete PI90LV047ALEX.

Parameter Comparison

Engineering Selection Recommendations

Both SN65LVDS047PW and SN65LVDS047PWR are direct functional equivalents to the PI90LV047ALEX. Selection between these two Texas Instruments alternatives is determined by packaging and supply chain requirements:

SN65LVDS047PW is supplied in Tube packaging, suitable for lower-volume applications and manual assembly processes.

SN65LVDS047PWR is supplied in Cut Tape (CT) & Digi-Reel® format with higher inventory availability (10,000 pcs), making it the preferred choice for high-volume production and automated assembly lines.

Both parts maintain identical electrical specifications, compliance certifications (ROHS3), and moisture sensitivity ratings. The transition from the obsolete PI90LV047ALEX to either active Texas Instruments part presents no functional risk when PCB layout and signal integrity requirements remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can SN65LVDS047PW and SN65LVDS047PWR be used interchangeably?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: Tube versus Cut Tape & Digi-Reel®. Selection depends on assembly process requirements and supply chain logistics.

Q: Is the 16-TSSOP package identical across all three parts?

A: Yes. All three parts use the 16-TSSOP package with 0.173" width and 4.40mm dimensions. PCB footprints and assembly processes are directly compatible.

Q: What compliance certifications apply to the substitute parts?

A: Both SN65LVDS047PW and SN65LVDS047PWR are ROHS3 compliant with MSL rating of 1 (Unlimited moisture sensitivity level). REACH status is unaffected for both parts.

Q: Are there any electrical performance differences between the PI90LV047ALEX and the substitute parts?

A: No. All three parts operate at identical supply voltage (3V ~ 3.6V), data rate (400Mbps), temperature range (-40°C ~ 85°C), and LVDS protocol specifications.

Q: Why is the PI90LV047ALEX classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Diodes Incorporated. The Texas Instruments equivalents (SN65LVDS047PW and SN65LVDS047PWR) are active products with ongoing production and support.
