73S8014RT-ILR/F Equivalent & Substitute Parts

Part Overview

The 73S8014RT-ILR/F is a specialized interface IC manufactured by Analog Devices Inc./Maxim Integrated, designed for set-top box applications. This component operates across a 2.7V to 5.5V supply voltage range and is housed in a 20-SOIC package with exposed pad. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, maintenance, and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 73S8014RT-ILR/F is determined by the following critical parameters:

• Functional Category: Interface IC classification
• Supply Voltage Range: Operating voltage compatibility (2.7V ~ 5.5V for the main part)
• Package Type: Surface mount configuration and physical dimensions
• Compliance Standards: RoHS3 compliance and REACH status
• Product Status: Active alternatives preferred for long-term availability

The substitute parts identified—PI3HDX1204B1ZHIEX and STUSBCD01BJR—are both active interface ICs with RoHS3 compliance and REACH unaffected status. However, each presents distinct trade-offs in voltage range, package form factor, and application focus that must be evaluated against specific system requirements.

Parameter Comparison

Engineering Selection Recommendations

PI3HDX1204B1ZHIEX is an active product from Diodes Incorporated with unlimited moisture sensitivity rating. The 42-TQFN package represents a significant form factor change from the original 20-SOIC, requiring PCB redesign. The supply voltage range of 3V to 3.6V is narrower than the original part, limiting applicability to systems with tightly regulated 3.3V supplies. This substitute is suitable only when application-specific requirements align with HDMI redriver and level shifter functionality.

STUSBCD01BJR is an active product from STMicroelectronics with unlimited moisture sensitivity rating. The 12-FlipChip package is substantially different from the 20-SOIC form factor and requires specialized assembly capabilities. The supply voltage range of 2.2V to 4.5V provides broader compatibility than PI3HDX1204B1ZHIEX but remains narrower than the original 2.7V to 5.5V specification. This substitute is applicable to mobile and portable device interfaces where the FlipChip package is acceptable.

Both substitutes offer improved moisture sensitivity characteristics and active product status, ensuring long-term availability and supply chain stability compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can PI3HDX1204B1ZHIEX directly replace 73S8014RT-ILR/F without PCB modification?

A: No. The PI3HDX1204B1ZHIEX uses a 42-TQFN package versus the original 20-SOIC package, requiring PCB layout redesign. Additionally, the voltage range limitation (3V to 3.6V) may not accommodate systems designed for the original 2.7V to 5.5V specification.

Q: What are the moisture sensitivity implications of switching to substitute parts?

A: Both substitute parts have MSL 1 (Unlimited) ratings compared to the original MSL 3 (168 Hours). This represents improved moisture tolerance and reduces handling and storage constraints during manufacturing and assembly.

Q: Is STUSBCD01BJR suitable for set-top box applications?

A: STUSBCD01BJR is specified for mobile phones, PDAs, smart devices, and personal media players. While both are interface ICs with compatible compliance standards, the application focus differs from the original set-top box designation. Functional compatibility must be verified against specific system requirements.

Q: Do all three parts maintain the same regulatory compliance?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8542.39.0001, ensuring equivalent regulatory standing.

Q: What is the primary limitation when considering these substitutes?

A: Package form factor represents the most significant constraint. The original 20-SOIC package differs substantially from both the 42-TQFN and 12-FlipChip alternatives, necessitating PCB redesign and potentially different assembly processes. Voltage range compatibility must also be verified against system specifications.
