Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD2702LD is determined by the following critical parameters:

• Output Voltage: ±10V fixed output (must match exactly)
• Output Current: 10 mA capability (must match or exceed)
• Tolerance: ±0.03% precision requirement
• Temperature Coefficient: 5ppm/°C stability
• Input Voltage Range: 13V ~ 18V compatibility
• Package Type: 14-CDIP through-hole form factor
• Supply Current: 17mA operational requirement

The AD2702SD/883B qualifies as a substitute based on matching all critical electrical parameters (output voltage, current, temperature coefficient, input voltage range, and supply current) and maintaining identical package configuration. The substitute part shares the same base product number (AD2702) and package specification, confirming functional equivalence for the core voltage reference application.

Parameter Comparison

Engineering Selection Recommendations

The AD2702SD/883B serves as a direct functional substitute for the AD2702LD. Both parts share identical electrical specifications for the core voltage reference function and are housed in the same 14-CDIP package, ensuring mechanical and electrical compatibility in existing circuit designs.

The AD2702SD/883B carries military-grade qualification (MIL-STD-883) and operates across an extended temperature range (-55°C ~ 125°C) compared to the commercial-grade AD2702LD (-25°C ~ 85°C). This extended specification provides additional operational margin for applications requiring broader environmental performance.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), supporting modern manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the AD2702SD/883B directly replace the AD2702LD in existing designs?

A: Yes. Both parts provide identical output voltage (±10V), output current (10 mA), temperature coefficient (5ppm/°C), input voltage range (13V ~ 18V), and supply current (17mA). The 14-CDIP package configuration is identical, enabling direct pin-for-pin substitution.

Q: What is the difference between the AD2702LD and AD2702SD/883B?

A: The primary differences are product grade and operating temperature range. The AD2702SD/883B is military-qualified to MIL-STD-883 with an extended operating temperature range of -55°C ~ 125°C, whereas the AD2702LD is commercial-grade with an operating range of -25°C ~ 85°C. The AD2702LD specifies ±0.03% tolerance; the AD2702SD/883B tolerance specification is not provided in available data.

Q: Are both parts available in the same package?

A: Yes. Both the AD2702LD and AD2702SD/883B are packaged in 14-CDIP (0.300", 7.62mm) through-hole configuration, ensuring identical footprint and mounting compatibility.

Q: What certifications apply to these parts?

A: The AD2702LD is standard commercial-grade. The AD2702SD/883B carries MIL-STD-883 military qualification. Both parts are ROHS3 compliant and REACH unaffected, with unlimited moisture sensitivity rating (MSL 1).

Q: Should I select the military-grade variant for non-military applications?

A: Selection depends on application requirements. The extended temperature range (-55°C ~ 125°C) of the AD2702SD/883B provides operational margin beyond commercial specifications. For applications operating within -25°C ~ 85°C, either part is suitable based on electrical equivalence.
