Key Parameters

Substitute Part Grouping Explanation

Substitution of the 73S8014R-ILR/F2 is determined by the following critical parameters:

• Functional Category: Both parts must operate as specialized interface ICs
• Supply Voltage Compatibility: The substitute must operate within or encompass the original supply voltage range (2.7V ~ 5.5V)
• Mounting Type: Surface mount compatibility is required
• RoHS Compliance: ROHS3 compliance ensures regulatory alignment
• Application Suitability: The substitute must support interface functionality for consumer electronics or related applications

The STUSBCD01BJR from STMicroelectronics qualifies as a substitute based on its classification as a specialized interface IC with surface mount packaging, active product status, and ROHS3 compliance. However, note that the STUSBCD01BJR operates at a reduced supply voltage range (2.2V ~ 4.5V) and uses a different package form factor (12-FlipChip vs. 20-SOIC), requiring circuit board redesign and validation.

Parameter Comparison

Engineering Selection Recommendations

The 73S8014R-ILR/F2 is obsolete and no longer manufactured. The STUSBCD01BJR is the identified substitute and maintains active production status with STMicroelectronics. Both components are ROHS3 compliant and suitable for surface mount assembly.

Key considerations for selection:

• Supply Voltage: The STUSBCD01BJR operates at a lower maximum supply voltage (4.5V vs. 5.5V). Verify that your system design operates within the 2.2V to 4.5V range.
• Package Transition: The change from 20-SOIC to 12-FlipChip requires PCB redesign and footprint modification.
• Moisture Sensitivity: The STUSBCD01BJR has superior moisture handling (MSL 1 vs. MSL 3), reducing risk in humid storage and assembly environments.
• Availability: The STUSBCD01BJR has significantly higher inventory availability (20,180 pcs vs. 1,089 pcs), supporting production continuity.

Frequently Asked Questions (FAQ)

Q: Can the STUSBCD01BJR be used as a direct drop-in replacement for the 73S8014R-ILR/F2?

A: No. While both are specialized interface ICs with surface mount mounting, the STUSBCD01BJR uses a 12-FlipChip package versus the 20-SOIC package of the original part. PCB redesign is required.

Q: What is the impact of the different supply voltage ranges?

A: The STUSBCD01BJR operates at 2.2V to 4.5V, while the 73S8014R-ILR/F2 operates at 2.7V to 5.5V. If your system requires operation above 4.5V, the STUSBCD01BJR is not suitable without circuit modification.

Q: Are both parts RoHS compliant?

A: Yes. Both the 73S8014R-ILR/F2 and STUSBCD01BJR are ROHS3 compliant, ensuring regulatory alignment for consumer electronics applications.

Q: What does the difference in Moisture Sensitivity Level mean?

A: MSL 3 (73S8014R-ILR/F2) allows 168 hours of exposure to moisture before soldering, while MSL 1 (STUSBCD01BJR) has unlimited moisture exposure tolerance. The STUSBCD01BJR is more robust in humid environments and storage conditions.

Q: Why is the STUSBCD01BJR recommended despite the package change?

A: The STUSBCD01BJR is the manufacturer-recommended substitute, maintains active production status, offers superior moisture handling, and has higher inventory availability. These factors support long-term supply chain reliability and system redesign feasibility.
