Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM4862MX is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Output power rating: 825mW at 8Ω load
• Supply voltage range: 2.7V to 5.5V
• Amplifier topology: Class AB
• Channel configuration: 1-Channel (Mono)
• Integrated protection features: Shutdown and Thermal Protection

Mechanical Compatibility Requirements:

• Package type: 8-SOIC
• Package dimensions: 0.154" width (3.90mm)
• Mounting technology: Surface Mount

Regulatory & Compliance Alignment:

• ECCN classification: EAR99
• HTSUS code: 8542.33.0001

Substitute parts must match all electrical parameters, maintain identical package specifications, and comply with the same regulatory classifications to ensure direct interchangeability without circuit redesign or PCB layout modification.

Parameter Comparison

Engineering Selection Recommendations

The LM4862MX/NOPB qualifies as a direct substitute for the obsolete LM4862MX based on complete electrical and mechanical parameter equivalence. The substitute part maintains identical output power specifications, supply voltage range, operating temperature range, package configuration, and integrated protection features.

The LM4862MX/NOPB carries Active product status, indicating ongoing manufacturer support and availability. This status provides supply chain continuity advantages over the obsolete LM4862MX. Both parts comply with identical regulatory classifications (ECCN: EAR99, HTSUS: 8542.33.0001), ensuring equivalent compliance posture for export and trade purposes.

No circuit modifications, PCB layout changes, or application firmware adjustments are required when transitioning from LM4862MX to LM4862MX/NOPB. Pin configuration, electrical performance, and thermal characteristics remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can LM4862MX/NOPB be used as a direct replacement for LM4862MX without PCB modifications?

A: Yes. The LM4862MX/NOPB is electrically and mechanically identical to the LM4862MX. Both devices share the same 8-SOIC package dimensions, pin configuration, output power rating (825mW @ 8Ω), supply voltage range (2.7V ~ 5.5V), operating temperature range (-40°C ~ 85°C), and integrated protection features. No PCB layout changes are required.

Q: What is the primary advantage of selecting LM4862MX/NOPB over LM4862MX?

A: The LM4862MX/NOPB carries Active product status, whereas the LM4862MX is classified as Obsolete. Active status ensures ongoing manufacturer support, continued availability, and long-term supply chain reliability for production applications.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both the LM4862MX and LM4862MX/NOPB share identical regulatory classifications: ECCN EAR99 and HTSUS 8542.33.0001. Compliance posture remains unchanged when substituting between these parts.

Q: What package specifications must be verified for substitution?

A: Both parts use the 8-SOIC package with 0.154" width (3.90mm). Package type, dimensions, and surface mount technology are identical. No package-related compatibility issues exist.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. Identical electrical parameters (Class AB topology, 825mW output power, 2.7V ~ 5.5V supply range, -40°C ~ 85°C operating temperature) and mechanical specifications (8-SOIC package, surface mount) enable direct interchangeability without design modifications.
