73S8010R-IM/F Equivalent & Substitute Parts

Part Overview

The 73S8010R-IM/F is a specialized interface IC manufactured by Analog Devices Inc./Maxim Integrated, designed for Set-Top Box applications. This component operates as a 32-QFN (5x5) surface mount device with I2C interface capability and a supply voltage range of 2.7V to 5.5V. The product is currently classified as obsolete, making identification of functionally equivalent substitute parts essential for system redesign, legacy support, and continued production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 73S8010R-IM/F are identified based on the following critical parameters that determine functional equivalence:

• Interface protocol compatibility (I2C support)
• Package form factor and mounting type (surface mount QFN variants)
• Supply voltage operating range overlap
• RoHS3 compliance and regulatory alignment
• Active product status for continued availability

The two identified substitute parts meet these criteria through different approaches: one maintains the same package footprint (32-QFN), while the other provides interface functionality within compatible voltage specifications and active product status.

Parameter Comparison

Engineering Selection Recommendations

Selection between substitute parts depends on specific design constraints:

The DP83822HFRHBR maintains the same 32-QFN (5x5) package footprint as the original 73S8010R-IM/F, enabling direct PCB layout compatibility. This part is manufactured by Texas Instruments and carries active product status with high inventory availability (100,344 pieces). However, the supply voltage range (1.71V ~ 3.45V) is narrower than the original specification and does not overlap the full 2.7V ~ 5.5V range. The interface protocol differs (MII, RMII versus I2C), requiring functional verification for application compatibility.

The ADN8102ACPZ-R7 is manufactured by Analog Devices Inc., the original equipment manufacturer, and maintains I2C interface compatibility with the 73S8010R-IM/F. This part carries active product status with 1,158 pieces in inventory. The supply voltage range (1.8V ~ 3.3V) is narrower than the original specification. The package footprint differs (64-LFCSP-VQ 9x9 versus 32-QFN 5x5), requiring PCB redesign and layout modifications.

Both substitute parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements equivalent to the original component.

Frequently Asked Questions (FAQ)

Q: Can the DP83822HFRHBR be used as a direct replacement for the 73S8010R-IM/F?

A: The DP83822HFRHBR shares the same 32-QFN (5x5) package footprint, enabling direct PCB placement compatibility. However, the interface protocol differs (MII/RMII versus I2C), and the supply voltage range is narrower (1.71V ~ 3.45V versus 2.7V ~ 5.5V). Functional compatibility must be verified against specific application requirements.

Q: What are the package differences between substitute options?

A: The DP83822HFRHBR maintains the original 32-QFN (5x5) package, requiring no PCB layout changes. The ADN8102ACPZ-R7 uses a larger 64-LFCSP-VQ (9x9) package, necessitating PCB redesign and increased board space allocation.

Q: Are both substitute parts compliant with the same regulatory standards?

A: Yes. Both the DP83822HFRHBR and ADN8102ACPZ-R7 are ROHS3 compliant and REACH unaffected, matching the regulatory status of the original 73S8010R-IM/F. Both carry EAR99 ECCN classification.

Q: Which substitute part has better inventory availability?

A: The DP83822HFRHBR has significantly higher inventory availability with 100,344 pieces in stock, compared to 1,158 pieces for the ADN8102ACPZ-R7.

Q: What is the impact of different Moisture Sensitivity Levels (MSL)?

A: The original 73S8010R-IM/F has MSL 1 (unlimited shelf life). The DP83822HFRHBR has MSL 2 (1 year), and the ADN8102ACPZ-R7 has MSL 3 (168 hours). Lower MSL ratings require stricter moisture control during storage and handling.

Q: Does the ADN8102ACPZ-R7 maintain I2C interface compatibility?

A: Yes. The ADN8102ACPZ-R7 supports I2C interface, matching the original 73S8010R-IM/F specification. However, the larger package footprint requires PCB layout modifications.
