TVP5145PFP Equivalent & Substitute Parts

Part Overview

The TVP5145PFP is a digital video decoder IC manufactured by Texas Instruments, designed for video signal processing in conferencing and set-top box applications. The device integrates analog and digital video decoding functionality in an 80-pin HTQFP package with exposed pad.

The TVP5145PFP carries an Obsolete product status, indicating it is no longer in active production. This necessitates identification of functionally equivalent substitute components that maintain compatibility with existing system designs while offering continued availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TVP5145PFP is determined by the following critical parameters:

• Package Compatibility: Identical 80-TQFP Exposed Pad (80-HTQFP 12x12) surface mount package ensures mechanical and electrical pin compatibility
• Functional Classification: Video decoder IC classification with equivalent signal processing capability
• Supply Voltage Ranges: Analog and digital supply voltage specifications must support the system's power delivery architecture
• Compliance Standards: RoHS3 and REACH compliance status must be maintained for regulatory continuity
• Moisture Sensitivity: MSL rating of 3 (168 Hours) establishes handling and storage requirements

The TVP5146PFP meets these substitution criteria through identical package geometry, equivalent functional classification, and matching compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The TVP5146PFP is the manufacturer-designated substitute for the TVP5145PFP based on identical package geometry and functional classification. Both devices carry discontinued product status: TVP5145PFP is classified as Obsolete, while TVP5146PFP is designated Not For New Designs.

Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment with current environmental and hazardous substance directives. The MSL 3 rating (168 Hours) applies uniformly to both components, establishing identical moisture handling and storage protocols.

The TVP5146PFP supports a broader analog and digital supply voltage specification (1.8V, 3.3V) compared to the TVP5145PFP (3.1V ~ 4.6V analog; 3V ~ 3.6V digital). Systems operating at 3.3V nominal supply voltage are compatible with both devices. Systems requiring the specific voltage ranges of the TVP5145PFP must verify TVP5146PFP compatibility with actual circuit operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the TVP5146PFP directly replace the TVP5145PFP in existing designs?

A: The TVP5146PFP is mechanically and electrically compatible through identical 80-TQFP Exposed Pad packaging and equivalent video decoder functionality. Voltage supply compatibility must be verified for your specific application. Both devices are discontinued products.

Q: What is the significance of the different product status designations?

A: TVP5145PFP is classified as Obsolete, indicating end-of-life status. TVP5146PFP is designated Not For New Designs, indicating limited availability and no recommended use in new product development. Both statuses reflect discontinued manufacturing.

Q: Are there compliance differences between these parts?

A: No. Both the TVP5145PFP and TVP5146PFP maintain identical RoHS3 compliance, REACH Unaffected status, and MSL 3 (168 Hours) moisture sensitivity ratings.

Q: What voltage specifications should I verify for substitution?

A: The TVP5145PFP operates at 3.1V ~ 4.6V (analog) and 3V ~ 3.6V (digital). The TVP5146PFP operates at 1.8V and 3.3V (both analog and digital). Confirm your system's actual supply voltage against both specifications before substitution.

Q: Is the packaging identical between these parts?

A: Yes. Both devices use the 80-TQFP Exposed Pad package (80-HTQFP 12x12) with surface mount configuration, ensuring identical PCB footprint and pin assignment compatibility.
