Substitute Part Grouping Explanation

Substitution of the AD780AR is determined by strict equivalence across the following critical parameters:

• Reference Type: Series, Shunt configuration
• Output Type: Programmable voltage reference capability
• Voltage Output Levels: ±2.5V, ±3V programmable selection
• Current Output: 10 mA minimum specification
• Tolerance: ±0.2% and ±0.17% accuracy classes
• Temperature Coefficient: 7ppm/°C thermal stability
• Noise Performance: 4µVp-p in the 0.1Hz to 10Hz band
• Input Voltage Range: 4V ~ 36V operating window
• Package: 8-SOIC form factor with identical pinout
• Mounting: Surface Mount technology

The AD780ARZ qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility across all parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

The AD780ARZ is the direct substitute for the obsolete AD780AR. Both components share identical electrical and mechanical specifications, ensuring pin-for-pin compatibility and functional equivalence in circuit applications.

The primary distinction between these parts is product status: the AD780AR is obsolete, while the AD780ARZ maintains active production status. The AD780ARZ carries RoHS3 compliance and REACH unaffected status, providing regulatory alignment for current manufacturing standards. Selection of the AD780ARZ eliminates obsolescence risk and ensures access to current inventory and manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the AD780ARZ directly replace the AD780AR in existing designs?

A: Yes. The AD780ARZ is electrically and mechanically identical to the AD780AR. Both components feature the same 8-SOIC package, identical pinout, and equivalent electrical performance across all specified parameters including voltage output, tolerance, temperature coefficient, and noise characteristics.

Q: What is the primary reason to transition from AD780AR to AD780ARZ?

A: The AD780AR is classified as obsolete. The AD780ARZ is the active production equivalent, ensuring continued availability, manufacturer support, and compliance with current regulatory standards including RoHS3 and REACH requirements.

Q: Are there packaging differences between AD780AR and AD780ARZ?

A: Both parts use the 8-SOIC package with identical dimensions (0.154", 3.90mm Width). The AD780ARZ is supplied in Tube packaging, while the AD780AR packaging specification was not provided. The functional package remains identical for circuit board assembly.

Q: Do these parts require different handling or storage procedures?

A: Both components share Moisture Sensitivity Level 1 (Unlimited), indicating identical moisture handling requirements. Standard ESD precautions and dry storage conditions apply to both parts.

Q: What compliance certifications apply to the AD780ARZ?

A: The AD780ARZ is RoHS3 compliant and REACH unaffected. Both parts carry EAR99 export classification and HTSUS code 8542.39.0001.
