IRS2092SPBF Class D Amplifier IC Equivalent & Substitute Parts

Part Overview

The IRS2092SPBF is a Class D monaural amplifier integrated circuit manufactured by Infineon Technologies, housed in a 16-SOIC surface mount package. This device is designed for low-power audio amplification applications requiring efficient power conversion with integrated protection features including depop and short-circuit protection. The IRS2092SPBF is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IRS2092SPBF is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 16-SOIC package format to ensure direct PCB footprint compatibility without layout modifications.

Amplifier Classification: Substitute parts must be Class D amplifier ICs to maintain equivalent operational characteristics and efficiency profiles.

Channel Configuration: Substitutes must be monaural (1-Channel) amplifiers to match the single-channel output architecture.

Protection Features: Substitute parts must include at minimum depop and short-circuit protection to ensure equivalent circuit protection levels.

Surface Mount Technology: All candidates must use surface mount packaging to align with manufacturing processes.

Regulatory Compliance: Substitute parts must maintain ROHS3 compliance and EAR99 ECCN classification for regulatory consistency.

The MAX4295ESE+ meets all substitution criteria based on these parameters. However, the supply voltage range differs significantly between the main part (10V ~ 18V) and the substitute (2.7V ~ 5.5V), indicating application-specific voltage domain requirements that must be evaluated during component selection.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The IRS2092SPBF is discontinued at DiGi Electronics, making the MAX4295ESE+ the primary active alternative. The MAX4295ESE+ maintains active product status with established supply chain availability.

Regulatory and Compliance Alignment: Both parts maintain ROHS3 compliance and EAR99 ECCN classification, ensuring equivalent regulatory standing for procurement and deployment.

Moisture Sensitivity: The MAX4295ESE+ offers superior moisture handling characteristics with MSL 1 (Unlimited) compared to the IRS2092SPBF MSL 2 (1 Year), reducing storage and handling constraints.

Supply Voltage Domain: The critical differentiator is the supply voltage range. The IRS2092SPBF operates at 10V ~ 18V, while the MAX4295ESE+ operates at 2.7V ~ 5.5V. Selection between these parts depends entirely on the application's power supply architecture. Direct substitution is only valid when the circuit operates within the MAX4295ESE+ voltage specification.

Operating Temperature Range: The IRS2092SPBF supports extended high-temperature operation to 125°C, while the MAX4295ESE+ is rated to 85°C. Applications requiring operation above 85°C cannot use the MAX4295ESE+ as a substitute.

Protection Feature Enhancement: The MAX4295ESE+ includes thermal protection and shutdown functionality in addition to the depop and short-circuit protection present in the IRS2092SPBF, providing enhanced circuit safeguarding.

Frequently Asked Questions (FAQ)

Q: Can the MAX4295ESE+ directly replace the IRS2092SPBF in existing designs?

A: Direct replacement is possible only if the application circuit operates within the MAX4295ESE+ supply voltage range of 2.7V ~ 5.5V. The IRS2092SPBF is specified for 10V ~ 18V operation. If the original design uses supply voltages above 5.5V, the MAX4295ESE+ cannot be substituted without circuit redesign.

Q: Are the 16-SOIC packages identical between these parts?

A: Both parts use 16-SOIC packaging with identical physical dimensions (0.154", 3.90mm Width). PCB footprints are compatible, and no layout modifications are required for package accommodation.

Q: What is the significance of the moisture sensitivity level difference?

A: The IRS2092SPBF has MSL 2 (1 Year), requiring component use within one year of manufacture. The MAX4295ESE+ has MSL 1 (Unlimited), eliminating time-based storage constraints. This affects inventory management and component shelf life considerations.

Q: Does the MAX4295ESE+ provide equivalent protection features?

A: The MAX4295ESE+ includes depop and short-circuit protection matching the IRS2092SPBF, plus additional thermal protection and shutdown functionality. Protection capability is equivalent or enhanced, not reduced.

Q: What is the maximum output power difference between these parts?

A: The IRS2092SPBF does not specify maximum output power in the provided parameters. The MAX4295ESE+ is rated for 2W output at 4Ohm load. Output power capability must be evaluated based on specific application requirements and load impedance.

Q: Can the MAX4295ESE+ be used in applications requiring operation above 85°C?

A: No. The MAX4295ESE+ operating temperature range is -40°C ~ 85°C. Applications requiring sustained operation above 85°C require alternative components rated for extended temperature ranges.

Q: Are there any regulatory or compliance concerns with substitution?

A: Both parts maintain ROHS3 compliance and EAR99 ECCN classification. No regulatory barriers exist for substitution from a compliance standpoint.
