AD724JR Equivalent & Substitute Parts

Part Overview

The AD724JR is a Video Encoder IC manufactured by Analog Devices Inc. that converts RGB signals to NTSC/PAL format. This interface component is packaged in a 16-SOIC surface mount configuration and operates with a digital supply voltage range of 4.75V to 5.25V. The AD724JR is classified as an obsolete product, making identification of compatible substitute parts essential for system maintenance, repair, and legacy design support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD724JR is determined by strict equivalence across the following critical parameters:

• Manufacturer and Base Product Number: Both the main part and substitute must originate from Analog Devices Inc. and share the base product number AD724 to ensure functional and pin-level compatibility.
• Package and Pinout: The 16-SOIC package with 0.295" width (7.50mm) is mandatory for direct PCB compatibility without layout modifications.
• Functional Classification: Both parts must be classified as Video Encoder ICs with RGB to NTSC/PAL conversion capability.
• Electrical Specifications: Digital supply voltage range of 4.75V to 5.25V must be identical to ensure operation within the same power distribution system.
• Moisture Sensitivity: MSL rating of 1 (Unlimited) ensures equivalent handling and storage requirements.

Parameter Comparison

Engineering Selection Recommendations

The AD724JRZ is a direct functional equivalent to the AD724JR. Both parts share identical electrical specifications, package geometry, and pinout configuration, enabling direct substitution at the component level.

The primary distinction between these parts is product lifecycle status: the AD724JR is obsolete, while the AD724JRZ maintains active production status. The AD724JRZ additionally carries ROHS3 compliance and REACH unaffected certification, meeting current environmental and regulatory requirements for new designs and manufacturing operations.

Selection between these parts should be based on availability and regulatory requirements of the target application. For legacy system repairs where original specifications must be maintained, the AD724JRZ provides equivalent performance. For new designs or systems requiring current compliance certifications, the AD724JRZ is the appropriate choice.

Frequently Asked Questions (FAQ)

Q: Can the AD724JRZ replace the AD724JR in existing designs?

A: Yes. The AD724JRZ is a direct substitute for the AD724JR. Both parts are identical in electrical performance, pinout, and package configuration. No circuit modifications or PCB layout changes are required.

Q: What is the difference between AD724JR and AD724JRZ?

A: The parts are functionally equivalent. The primary differences are product status (AD724JR is obsolete; AD724JRZ is active) and compliance certifications (AD724JRZ carries ROHS3 and REACH documentation). Packaging differs (AD724JRZ is supplied in tubes).

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. Both parts operate within the identical voltage range (4.75V to 5.25V), use the same 16-SOIC package, and perform RGB to NTSC/PAL encoding without functional variation.

Q: Which part should be selected for new production?

A: The AD724JRZ should be selected for new production due to its active product status and current compliance certifications (ROHS3, REACH unaffected).

Q: Is the 16-SOIC package critical for substitution?

A: Yes. The 16-SOIC package with 0.295" width is mandatory for direct PCB compatibility. Alternative packages would require circuit board redesign and are not considered direct substitutes.
