Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SN75DP122RTQR is determined by strict alignment of the following critical parameters:

• Functional Application: DVI and HDMI signal switching capability
• Interface Protocol: TMDS support
• Supply Voltage Range: 4.5V to 5.25V operation
• Package Type: 56-VFQFN Exposed Pad (56-QFN 8x8)
• Mounting Technology: Surface mount configuration
• Compliance Standards: ROHS3 compliance, MSL 3 rating

The SN75DP122ARTQR qualifies as a direct substitute based on identical electrical specifications, package geometry, and compliance certifications. The primary distinction is product status and packaging format (Tape & Reel vs. standard packaging).

Frequently Asked Questions (FAQ)

Q: Can the SN75DP122ARTQR directly replace the SN75DP122RTQR in existing designs?

A: Yes. Both parts are electrically and mechanically identical. They share the same supply voltage range (4.5V to 5.25V), TMDS interface protocol, 56-QFN (8x8) package geometry, and compliance certifications. No design modifications are required.

Q: What is the difference between the two part numbers?

A: The primary differences are product status and packaging format. The SN75DP122RTQR is obsolete with standard packaging, while the SN75DP122ARTQR is active production with Tape & Reel packaging. The electrical and functional specifications are identical.

Q: Are there any PCB layout or assembly considerations when switching between these parts?

A: No. Both parts use the identical 56-VFQFN Exposed Pad package with 56-QFN (8x8) geometry. PCB footprints, solder pad layouts, and assembly processes remain unchanged.

Q: What does MSL 3 (168 Hours) mean for component handling?

A: Moisture Sensitivity Level 3 indicates the component requires controlled storage conditions. The 168-hour specification defines the maximum time the component can be exposed to ambient conditions (typically 30°C, 60% relative humidity) before requiring baking prior to soldering.

Q: Why is the SN75DP122RTQR marked as obsolete?

A: Obsolete status indicates Texas Instruments has discontinued active production and support for this specific part number. The SN75DP122ARTQR represents the active equivalent, ensuring continued availability and manufacturer support.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the SN75DP122RTQR and SN75DP122ARTQR are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements for electronic components.
