Substitute Part Grouping Explanation

Substitution eligibility for the AD783JR is determined by strict equivalence across the following critical parameters:

• Amplifier Type: Sample and Hold functionality
• Number of Circuits: Single circuit configuration
• Bandwidth Performance: -3dB Bandwidth of 15 MHz
• Input Bias Current: 100 nA
• Supply Current: 9.5 mA
• Output Current per Channel: 5 mA
• Supply Voltage Range: 9.5V to 10.5V
• Operating Temperature Range: 0°C to 70°C
• Package Configuration: 8-SOIC surface mount with 3.90mm width
• Moisture Sensitivity Level: MSL 1 (Unlimited)

Substitute parts must match all electrical and mechanical parameters without deviation. Packaging format differences (such as tube versus alternative packaging) do not affect functional equivalence when the base package type remains 8-SOIC.

Parameter Comparison

Engineering Selection Recommendations

The AD783JRZ serves as a direct functional equivalent to the AD783JR across all specified electrical and mechanical parameters. Both devices are manufactured by Analog Devices Inc. and share identical performance characteristics within the sample and hold amplifier category.

The primary distinction between these parts is product lifecycle status: the AD783JR is classified as Obsolete, while the AD783JRZ maintains Active status. The AD783JRZ additionally carries ROHS3 compliance certification and REACH Unaffected status, providing enhanced regulatory alignment for new designs and ongoing production.

For applications currently utilizing the AD783JR, the AD783JRZ provides direct substitution without circuit redesign or performance degradation. The tube packaging format of the AD783JRZ does not affect electrical or mechanical compatibility with existing board layouts designed for the 8-SOIC package configuration.

Frequently Asked Questions (FAQ)

Q: Can the AD783JRZ directly replace the AD783JR in existing designs?

A: Yes. The AD783JRZ is electrically and mechanically equivalent to the AD783JR. All critical parameters including bandwidth, supply voltage range, bias current, output current, operating temperature range, and package dimensions are identical. Direct substitution is supported without circuit modification.

Q: What is the significance of the product status difference between these parts?

A: The AD783JR is classified as Obsolete, indicating that Analog Devices Inc. has discontinued active production and support. The AD783JRZ maintains Active status, ensuring continued availability, technical support, and compliance with current regulatory standards. For new production and long-term supply chain planning, the AD783JRZ is the recommended selection.

Q: Does the tube packaging of the AD783JRZ affect compatibility?

A: No. Packaging format (tube versus other formats) does not affect the electrical performance or physical footprint of the 8-SOIC component. The device dimensions, pin configuration, and mounting characteristics remain identical. Tube packaging is a distribution and handling format only.

Q: Are there compliance differences between the AD783JR and AD783JRZ?

A: The AD783JRZ carries ROHS3 compliance certification and REACH Unaffected status. These certifications confirm compliance with European Union environmental and chemical safety regulations. The AD783JR compliance status is not specified in available documentation. For applications subject to regulatory compliance requirements, the AD783JRZ provides documented certification.

Q: What parameters determine substitution eligibility for sample and hold amplifiers?

A: Substitution eligibility is determined by equivalence across amplifier type, circuit count, bandwidth performance, input and output current specifications, supply voltage range, operating temperature range, package configuration, and moisture sensitivity level. All parameters must match exactly. Deviations in any specified parameter disqualify a part from direct substitution.
