73S8014RT-IL/F Equivalent & Substitute Parts

Part Overview

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

Key Parameters

Substitute Part Grouping Explanation

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

• Category Classification: Both parts must function as interface components
• Supply Voltage Compatibility: The substitute must operate within or encompass the 2.7V to 5.5V range
• Mounting Technology: Surface mount compatibility is required
• Regulatory Compliance: RoHS3 and REACH compliance status must be maintained or improved
• Application Domain: Interface functionality for consumer electronics applications

The FSA3031UMX has been identified as a manufacturer-recommended substitute. While this part operates at a different supply voltage (5.25V) and is housed in a different package format (12-UFQFN versus 20-SOIC), it maintains interface category classification and serves comparable consumer electronics applications including digital media devices.

Parameter Comparison

Engineering Selection Recommendations

Selection between the 73S8014RT-IL/F and FSA3031UMX must account for the following factors:

Product Status Consideration: The 73S8014RT-IL/F is obsolete, while the FSA3031UMX maintains active production status. For new designs or long-term system support, the active-status FSA3031UMX provides supply chain continuity.

Voltage Supply Differential: The 73S8014RT-IL/F operates across 2.7V to 5.5V, whereas the FSA3031UMX is specified at 5.25V. Circuit designs operating below 5.25V require verification of FSA3031UMX compatibility or identification of alternative substitutes.

Package Footprint Change: Migration from 20-SOIC to 12-UFQFN requires PCB layout modification. The 12-UFQFN package (1.8x1.8mm) represents a significant size reduction compared to the 20-SOIC format, necessitating board redesign.

Regulatory Alignment: Both components share identical ECCN and HTSUS classifications. RoHS3 and REACH compliance status for the FSA3031UMX should be confirmed with the manufacturer prior to implementation in regulated applications.

Frequently Asked Questions (FAQ)

Q: Can the FSA3031UMX directly replace the 73S8014RT-IL/F without PCB modification?

A: No. The FSA3031UMX uses a 12-UFQFN package versus the 20-SOIC package of the original part. PCB layout redesign is required. Pin-to-pin functional equivalence cannot be assumed without detailed datasheet comparison.

Q: What is the primary reason for seeking a substitute for the 73S8014RT-IL/F?

A: The 73S8014RT-IL/F is classified as obsolete. Manufacturer discontinuation necessitates identification of active-production alternatives for ongoing system support and component procurement.

Q: Is the FSA3031UMX suitable for applications requiring 2.7V operation?

A: The FSA3031UMX is specified at 5.25V. Applications requiring operation below this voltage require alternative component evaluation or circuit redesign to accommodate the higher minimum voltage requirement.

Q: Are both parts compliant with RoHS3 and REACH regulations?

A: The 73S8014RT-IL/F is confirmed ROHS3 Compliant and REACH Unaffected. RoHS3 and REACH compliance status for the FSA3031UMX is not provided in the available technical data and must be verified with Fairchild Semiconductor.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by interface category classification, supply voltage compatibility, surface mount technology, regulatory compliance status, and functional application domain. Package format and pin count may differ if circuit redesign is feasible.
