Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSM2301RMZ-R2 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Amplifier type: Class D mono configuration
• Package format: 8-MSOP surface mount
• Operating temperature range: -40°C ~ 85°C minimum
• Feature set: Depop, differential inputs, short-circuit and thermal protection, shutdown capability
• Manufacturer: Analog Devices Inc.

Performance Considerations:

• Supply voltage range must encompass or exceed the original 2.5V ~ 5V specification
• Output power specifications may vary based on load impedance
• Functional feature parity across protection and control mechanisms

The SSM2305RMZ-R2 qualifies as a direct substitute based on identical package geometry, matching operating temperature range, equivalent feature set, and compatible supply voltage envelope. The substitute part maintains all protective and control functions while offering enhanced output power capability and active product status.

Supply Voltage Compatibility: The SSM2305RMZ-R2 supply voltage range (2.2V ~ 5.5V) encompasses the original specification (2.5V ~ 5V), providing enhanced operational flexibility without circuit modification.

Inventory Availability: The SSM2305RMZ-R2 maintains significantly higher inventory levels (3645 Pcs) compared to the obsolete SSM2301RMZ-R2, supporting both immediate procurement and long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the SSM2305RMZ-R2 be used as a direct replacement for the SSM2301RMZ-R2 without circuit modifications?

A: Yes. Both devices share identical package geometry (8-MSOP), operating temperature range (-40°C ~ 85°C), and feature set. The SSM2305RMZ-R2 supply voltage range (2.2V ~ 5.5V) encompasses the original specification, eliminating the need for circuit redesign.

Q: What is the primary difference between these two amplifier ICs?

A: The SSM2305RMZ-R2 delivers higher output power (2.8W @ 4Ω) compared to the SSM2301RMZ-R2 (1.52W @ 8Ω), with an extended supply voltage range (2.2V ~ 5.5V versus 2.5V ~ 5V). Both maintain identical Class D mono architecture and protective features.

Q: Why is the SSM2301RMZ-R2 classified as obsolete?

A: The SSM2301RMZ-R2 has reached end-of-life status with Analog Devices Inc. The SSM2305RMZ-R2 represents the active product line continuation, offering improved performance specifications and ongoing manufacturing support.

Q: Are there any compliance differences between the SSM2301RMZ-R2 and SSM2305RMZ-R2?

A: Both parts share identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications. The SSM2305RMZ-R2 carries RoHS3 compliance and REACH unaffected status, meeting current regulatory standards for new designs.

Q: What packaging options are available for the SSM2305RMZ-R2?

A: The SSM2305RMZ-R2 is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, both utilizing the 8-MSOP surface mount package type identical to the original SSM2301RMZ-R2.

Q: Can the SSM2305RMZ-R2 operate at the minimum supply voltage of the SSM2301RMZ-R2?

A: Yes. The SSM2305RMZ-R2 minimum supply voltage is 2.2V, which is lower than the SSM2301RMZ-R2 minimum of 2.5V, providing enhanced operational flexibility across the entire original voltage range.

Q: Is the SSM2305RMZ-R2 suitable for applications requiring the exact output power specification of the SSM2301RMZ-R2?

A: The SSM2305RMZ-R2 delivers higher output power (2.8W @ 4Ω) than the original device. Applications requiring the specific 1.52W @ 8Ω output power must verify that the increased power capability does not introduce thermal or acoustic considerations in the target application.
