Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX922MSA/PR+ is determined by strict alignment with the following critical parameters:

Primary Substitution Criteria:

• Dual-element general-purpose comparator architecture
• CMOS output with rail-to-rail and TTL compatibility
• Supply voltage range: 2.5V ~ 11V (single) or ±1.25V ~ 5.5V (dual)
• Input offset voltage maximum of 10mV @ 5V
• Output current capability of 50mA typical
• Quiescent current not exceeding 3.2µA
• CMRR and PSRR minimum 40dB typical
• Propagation delay maximum 12µs
• Operating temperature range -55°C ~ 125°C
• 8-SOIC surface mount package (0.154", 3.90mm width)
• Active product status with current manufacturing support

Compliance Requirements:

• ROHS3 compliance mandatory
• MSL rating of 1 or better
• REACH unaffected status

Only components meeting all specified parameters qualify as direct substitutes. No parameter relaxation or approximation is permitted.

Parameter Comparison

Engineering Selection Recommendations

Component selection must be based on the following engineering criteria:

Product Status Consideration: Both the main part and substitute maintain active production status, ensuring long-term availability and manufacturing consistency.

Compliance Verification: All substitute components must maintain ROHS3 compliance and REACH unaffected status to meet regulatory requirements for electronic component deployment.

Certification Alignment: MSL rating of 1 (unlimited) ensures compatibility with standard PCB assembly processes without additional moisture control measures.

Electrical Performance Matching: Substitutes must deliver identical electrical performance across all specified parameters, including supply voltage range, input offset voltage, output current capability, and propagation delay characteristics.

Package Compatibility: The 8-SOIC surface mount package specification is non-negotiable for PCB layout and assembly compatibility.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the MAX922MSA/PR+? A: A valid substitute must match all specified electrical parameters, including dual-element architecture, CMOS rail-to-rail TTL output, supply voltage range of 2.5V ~ 11V or ±1.25V ~ 5.5V, input offset voltage of 10mV @ 5V maximum, output current of 50mA typical, quiescent current of 3.2µA maximum, CMRR/PSRR of 40dB typical, propagation delay of 12µs maximum, and operating temperature range of -55°C ~ 125°C. The component must also be packaged in 8-SOIC surface mount format with active product status and ROHS3 compliance.

Q: Can components with different package types substitute for the MAX922MSA/PR+? A: No. The 8-SOIC (0.154", 3.90mm width) surface mount package is a mandatory specification. Alternative package types are not acceptable substitutes due to PCB layout and assembly incompatibility.

Q: Are there any relaxations permitted for electrical parameters? A: No. All electrical parameters must match exactly as specified. Parameter relaxation or approximation is not permitted for substitute component selection.

Q: What compliance certifications are required for substitute parts? A: Substitute components must maintain ROHS3 compliance and REACH unaffected status. MSL rating must be 1 or better to ensure compatibility with standard assembly processes.

Q: How does product status affect substitution eligibility? A: Only components with active product status qualify as substitutes. This ensures manufacturing continuity and long-term component availability for production and field replacement applications.
