Key Parameters

Substitute Part Grouping Explanation

Substitution of the 73S8024RN-32IMR/F is determined by the following critical parameters:

• Functional Category: Interface IC for set-top box and pay TV decoder applications
• Supply Voltage Compatibility: Operating voltage range must support the system requirements
• Package Type: Surface mount QFN packages with exposed pad
• RoHS Compliance: ROHS3 compliance required for regulatory alignment
• Moisture Sensitivity: MSL rating appropriate for manufacturing and storage conditions

The NCN8025MTTBG from onsemi qualifies as a substitute based on shared functional application in set-top box and pay TV decoder interfaces, surface mount QFN packaging with exposed pad, ROHS3 compliance, and compatible supply voltage specifications. While the NCN8025MTTBG operates in a 16-QFN (3x3) package versus the 32-QFN (5x5) of the original part, both components serve equivalent interface roles in the same application domain.

Parameter Comparison

Engineering Selection Recommendations

The NCN8025MTTBG is actively manufactured and stocked by onsemi with 17,400 units available, providing supply continuity for the discontinued 73S8024RN-32IMR/F. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent applications. The NCN8025MTTBG demonstrates superior moisture handling with MSL 1 (unlimited) versus MSL 3 (168 hours), reducing moisture-related risk during manufacturing and storage. Supply voltage specifications for the NCN8025MTTBG (1.8V, 3V, 5V) encompass the operating range of the original part (2.7V ~ 5.5V), ensuring compatibility with existing system power architectures. Both components share identical ECCN and HTSUS classifications, maintaining consistent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the NCN8025MTTBG directly replace the 73S8024RN-32IMR/F in existing designs?

A: Both components serve equivalent interface functions in set-top box and pay TV decoder applications. The NCN8025MTTBG operates within the supply voltage range of the original part and maintains identical regulatory compliance. However, the package size differs (16-QFN versus 32-QFN), requiring PCB layout evaluation for pin-to-pin compatibility and signal routing.

Q: What is the significance of the different package sizes?

A: The 73S8024RN-32IMR/F uses a 32-QFN (5x5) package, while the NCN8025MTTBG uses a 16-QFN (3x3) package. This difference affects PCB footprint, pin count, and board space requirements. Design integration requires verification that the reduced pin count and smaller footprint align with system architecture.

Q: How do the moisture sensitivity levels compare?

A: The 73S8024RN-32IMR/F has MSL 3 (168 hours), while the NCN8025MTTBG has MSL 1 (unlimited). MSL 1 indicates superior moisture resistance and eliminates time-based storage constraints, reducing manufacturing risk and improving supply chain flexibility.

Q: Are both parts compliant with current regulatory standards?

A: Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components in consumer and industrial applications.

Q: What supply voltage specifications apply to each part?

A: The 73S8024RN-32IMR/F operates at 2.7V to 5.5V. The NCN8025MTTBG operates at 1.8V, 3V, and 5V discrete levels. System power supply specifications must be evaluated to confirm compatibility with the NCN8025MTTBG's discrete voltage requirements.
