PI3HDMI621FBEX Equivalent & Substitute Parts

Part Overview

The PI3HDMI621FBEX is a specialized interface IC manufactured by Diodes Incorporated in a 48-LQFP package (7x7mm). This component is designed for HDMI applications and is currently classified as obsolete. Due to its obsolete status, identifying functionally equivalent substitute parts is essential for system redesign, legacy product support, and procurement continuity. The following substitute parts maintain compatibility based on shared electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitute parts for the PI3HDMI621FBEX are identified based on the following criteria:

Primary Compatibility Parameters:

• Interface category classification
• Surface mount mounting type
• 48-pin package format with 7x7mm footprint
• ROHS3 compliance and REACH unaffected status
• Supply voltage compatibility (3.3V)

Substitute Classification:

The PI3HDX621FBE (Diodes Incorporated) serves as a direct manufacturer alternative, maintaining the same 48-LQFP (7x7mm) package and interface category while transitioning from HDMI to Sink Switch applications.

The 14315R-100 (Renesas Electronics Corporation) and ECE1088-DZK (Microchip Technology) represent functional interface alternatives with different package formats (48-QFN and 28-QFN respectively) and application domains (Router and GPIO Expansion Device), suitable for designs where package footprint flexibility exists.

Parameter Comparison

Engineering Selection Recommendations

PI3HDX621FBE (Diodes Incorporated): This part is the preferred direct substitute for the PI3HDMI621FBEX. It maintains identical package geometry (48-LQFP, 7x7mm), identical pin count, and equivalent interface classification. Both parts are ROHS3 compliant and REACH unaffected. The PI3HDX621FBE is currently in active production status, ensuring long-term availability. The primary design consideration is the transition from HDMI to Sink Switch application context; however, the electrical and mechanical compatibility remains valid for interface IC substitution.

14315R-100 (Renesas Electronics Corporation): This part provides an alternative interface solution with a different package format (48-QFN versus 48-LQFP). While both packages contain 48 pins and maintain a 7x7mm footprint, the QFN package has different land pattern requirements. This substitute is suitable for designs where PCB layout can accommodate QFN footprint modifications. The part is RoHS compliant and actively produced.

ECE1088-DZK (Microchip Technology): This part represents a functional interface alternative with a reduced pin count (28 pins) and smaller footprint (28-QFN, 5x5mm). This substitute is applicable only to designs where GPIO expansion functionality is compatible with the original HDMI interface requirements and where PCB space constraints favor a smaller package. The part is ROHS3 compliant, REACH unaffected, and actively produced.

Frequently Asked Questions (FAQ)

Q: Can PI3HDX621FBE be used as a direct replacement for PI3HDMI621FBEX without PCB modifications?

A: Yes. Both parts use the 48-LQFP (7x7mm) package with identical pin counts and footprints. No PCB layout changes are required for mechanical compatibility. Functional compatibility depends on application-specific requirements.

Q: What is the primary difference between the PI3HDMI621FBEX and PI3HDX621FBE?

A: The main difference is application context: PI3HDMI621FBEX is designed for HDMI applications, while PI3HDX621FBE is designed for Sink Switch applications. Both are interface ICs in the same package format. The PI3HDX621FBE is currently in active production, whereas the PI3HDMI621FBEX is obsolete.

Q: Can 14315R-100 replace PI3HDMI621FBEX on existing PCBs?

A: 14315R-100 uses a 48-QFN package instead of 48-LQFP. While both packages are 7x7mm with 48 pins, the land patterns differ. PCB redesign is required for this substitution.

Q: Is ECE1088-DZK suitable as a substitute?

A: ECE1088-DZK is a 28-pin interface IC in a 5x5mm QFN package. This part is suitable only if the application can function with reduced pin count and GPIO expansion functionality. It requires significant PCB redesign and is not a direct mechanical or functional replacement.

Q: What compliance certifications should I verify when selecting a substitute?

A: All listed substitute parts maintain ROHS3 compliance or equivalent RoHS compliance. Verify REACH unaffected status for your specific regulatory requirements. MSL ratings differ; ensure storage and handling procedures match the selected part's moisture sensitivity level.

Q: Why is the original PI3HDMI621FBEX obsolete?

A: Product obsolescence is determined by the manufacturer. Active alternatives from the same manufacturer (PI3HDX621FBE) or competing manufacturers (14315R-100, ECE1088-DZK) are available for new designs or legacy product support.
