Key Parameters

Substitute Part Grouping Explanation

Substitution of the IS31AP2110-ZLS2 is determined by the following critical parameters:

Functional Equivalence Criteria:

• Amplifier topology: Class D architecture
• Output configuration: Support for 1-Channel (Mono) or 2-Channel (Stereo) operation
• Supply voltage compatibility: Operating range must encompass or exceed 8V ~ 26V
• Output power capability: Minimum 15W per channel at 8Ω load
• Protection features: Short-circuit protection and depop functionality
• Mounting technology: Surface mount package with exposed pad design

Compliance & Regulatory Alignment:

• RoHS3 compliance status
• REACH unaffected classification
• ECCN and HTSUS code alignment (EAR99, 8542.33.0001)

The PAM8823FBE48-13 from Diodes Incorporated meets these substitution criteria through equivalent Class D topology, dual-channel stereo/mono capability, enhanced output power specifications, and broader supply voltage range, while maintaining regulatory compliance and surface mount packaging.

Engineering Selection Recommendations

Primary Substitute: PAM8823FBE48-13

The PAM8823FBE48-13 is the manufacturer-recommended substitute for the obsolete IS31AP2110-ZLS2. Selection of this alternative is supported by the following engineering factors:

Product Status & Availability: The PAM8823FBE48-13 maintains active product status with 837 units in current inventory, ensuring long-term supply chain continuity compared to the obsolete IS31AP2110-ZLS2.

Functional Compatibility: Both devices employ Class D amplifier topology and support identical output configurations (mono or stereo). The PAM8823FBE48-13 delivers enhanced output power specifications (25W x 2 @ 8Ω, 50W x 1 @ 4Ω) while maintaining backward compatibility with the original 15W requirement.

Supply Voltage Compatibility: The PAM8823FBE48-13 operates across 4.5V ~ 26V, which encompasses the IS31AP2110-ZLS2 operating range of 8V ~ 26V. This extended lower voltage limit provides additional design flexibility.

Regulatory & Compliance Alignment: Both parts maintain ROHS3 compliance, REACH unaffected status, and identical ECCN/HTSUS classifications, ensuring regulatory continuity in production environments.

Packaging Considerations: The PAM8823FBE48-13 uses a 48-LQFP package compared to the 28-TSSOP of the original part. PCB layout redesign is required. The PAM8823FBE48-13 features improved moisture sensitivity (MSL 1 vs. MSL 3), reducing handling and storage constraints.

Frequently Asked Questions (FAQ)

Q: Can the PAM8823FBE48-13 directly replace the IS31AP2110-ZLS2 without PCB modifications?

A: No. The PAM8823FBE48-13 uses a 48-LQFP package while the IS31AP2110-ZLS2 uses a 28-TSSOP package. PCB layout redesign is required. Pin-to-pin compatibility does not exist between these packages.

Q: What are the key electrical differences between these parts?

A: The PAM8823FBE48-13 provides higher output power (25W x 2 @ 8Ω versus 15W x 2 @ 8Ω) and extends the lower supply voltage limit to 4.5V. Both maintain Class D topology and mono/stereo output capability. The original 15W specification is fully supported by the substitute.

Q: Is the PAM8823FBE48-13 suitable for designs requiring the full 8V ~ 26V supply range of the original part?

A: Yes. The PAM8823FBE48-13 operates across 4.5V ~ 26V, which fully encompasses the original 8V ~ 26V range. No supply voltage compatibility issues exist.

Q: What is the impact of the different moisture sensitivity levels?

A: The IS31AP2110-ZLS2 has MSL 3 (168 hours), while the PAM8823FBE48-13 has MSL 1 (unlimited). The substitute part has less stringent moisture handling requirements, reducing storage and handling constraints during manufacturing.

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

A: Yes. Both the IS31AP2110-ZLS2 and PAM8823FBE48-13 are ROHS3 compliant, REACH unaffected, and share identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications.

Q: Why is the PAM8823FBE48-13 designated as the manufacturer-recommended substitute?

A: The PAM8823FBE48-13 is the manufacturer-recommended substitute because it maintains active product status, provides equivalent or superior electrical performance, ensures regulatory compliance continuity, and is available in current inventory quantities.
