Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD680JR is determined by strict equivalence across the following critical parameters:

• Fixed output voltage of 2.5V
• Output current capability of 10 mA
• Voltage tolerance of ±0.4%
• Temperature coefficient of 25 ppm/°C
• Noise specification of 10 µVp-p (0.1Hz to 10Hz)
• Input voltage range of 4.5V ~ 36V
• Supply current of 280 µA
• Operating temperature range of 0°C ~ 70°C
• 8-SOIC surface mount package configuration

The AD680JRZ qualifies as a direct substitute based on identical electrical specifications and package geometry. The primary distinction is product status: AD680JRZ is active, whereas AD680JR is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The AD680JRZ is the appropriate substitute for the obsolete AD680JR. Both components are manufactured by Analog Devices Inc. and maintain identical electrical and mechanical specifications. The AD680JRZ carries active product status, ensuring continued availability and manufacturing support. The AD680JRZ is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements. Selection of AD680JRZ eliminates obsolescence risk while maintaining full functional and physical compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can AD680JRZ be used as a direct replacement for AD680JR?

A: Yes. The AD680JRZ is electrically and mechanically identical to the AD680JR. Both components provide 2.5V fixed output with ±0.4% tolerance, 10 mA output current, and are housed in 8-SOIC surface mount packages. The primary difference is product status: AD680JRZ is active while AD680JR is obsolete.

Q: What is the significance of the product status difference?

A: Product status indicates manufacturing and support availability. The obsolete status of AD680JR means Analog Devices Inc. no longer manufactures this variant. The AD680JRZ, being active, ensures continued production and technical support.

Q: Are there packaging differences between AD680JR and AD680JRZ?

A: Both components use identical 8-SOIC (0.154", 3.90mm Width) surface mount packages. The packaging specification is 8-SOIC for both parts, ensuring PCB layout and assembly compatibility.

Q: Do compliance certifications differ between these parts?

A: The AD680JRZ includes RoHS3 compliance and REACH unaffected status. Both components maintain Moisture Sensitivity Level 1 (Unlimited). The AD680JRZ meets current regulatory requirements for electronic components.

Q: What electrical parameters must remain constant for substitution?

A: The following parameters must be identical: fixed output voltage (2.5V), output current (10 mA), voltage tolerance (±0.4%), temperature coefficient (25 ppm/°C), noise specification (10 µVp-p at 0.1Hz to 10Hz), input voltage range (4.5V ~ 36V), supply current (280 µA), and operating temperature range (0°C ~ 70°C).
