Key Parameters

Substitute Part Grouping Explanation

Substitution of the KAF-8300-AXC-CP-AA is determined by the following critical parameters:

• Sensor Technology: The main part uses CCD technology. Substitute parts may employ alternative sensor technologies (such as CMOS) provided they deliver equivalent or superior imaging performance within the application's operational constraints.
• Resolution and Pixel Array: The 8.3MP resolution with 3326H x 2504V pixel array establishes the baseline imaging capability. Substitute parts must maintain or exceed this resolution to ensure compatibility with existing optical systems.
• Pixel Size: The 5.4µm x 5.4µm pixel size affects light-gathering capability and noise characteristics. Substitute parts with different pixel sizes may require optical system recalibration.
• Supply Voltage: The 14.5V to 15.5V supply requirement is specific to CCD operation. CMOS alternatives operate at significantly lower voltages (1.7V to 2.9V), requiring power supply redesign.
• Package Type: The 32-CDIP module package is a mechanical constraint. Substitute parts in different packages (such as 163-CLGA) require PCB layout and mechanical housing modifications.
• Operating Temperature Range: The -10°C to 70°C range defines thermal operating limits. Substitute parts with extended temperature ranges provide greater operational flexibility.
• Product Status and Compliance: Active product status with current RoHS3 compliance ensures long-term availability and regulatory alignment.

The NOIX1SN8000B-LTI is identified as a substitute based on equivalent megapixel output (8.3MP equivalent through 4096H x 2160V resolution) and active product status, despite differences in sensor type, pixel size, package, and supply voltage.

Parameter Comparison

Engineering Selection Recommendations

The KAF-8300-AXC-CP-AA is obsolete and no longer in active production. The NOIX1SN8000B-LTI is an active product from the same manufacturer with current RoHS3 compliance and extended operating temperature range (-40°C to 85°C), providing superior long-term availability and regulatory support.

Selection of the NOIX1SN8000B-LTI requires evaluation of the following design impacts:

• Power Supply Architecture: The substitute operates at 1.7V to 2.9V versus the original 14.5V to 15.5V, necessitating complete power supply redesign.
• Package and PCB Layout: The transition from 32-CDIP to 163-BCLGA requires new PCB layout and mechanical integration.
• Optical System Recalibration: The pixel size reduction from 5.4µm to 3.2µm affects light-gathering characteristics and may require lens system adjustment.
• Sensor Technology Transition: The shift from CCD to CMOS introduces different noise characteristics, dynamic range, and signal processing requirements.

Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the NOIX1SN8000B-LTI be used as a direct drop-in replacement for the KAF-8300-AXC-CP-AA?

A: No. While both are onsemi optical sensors with comparable megapixel output, they differ in package type (32-CDIP versus 163-BCLGA), supply voltage (14.5V-15.5V versus 1.7V-2.9V), and sensor technology (CCD versus CMOS). Direct substitution requires PCB redesign, power supply modification, and optical system recalibration.

Q: What are the key differences between CCD and CMOS sensor types?

A: The KAF-8300-AXC-CP-AA uses CCD technology, while the NOIX1SN8000B-LTI uses CMOS technology. These represent different sensor architectures with distinct electrical characteristics, noise profiles, and signal processing requirements. The choice between them depends on application-specific imaging performance criteria.

Q: Does the pixel size difference affect image quality?

A: Pixel size influences light-gathering capability and noise characteristics. The KAF-8300-AXC-CP-AA has 5.4µm pixels, while the NOIX1SN8000B-LTI has 3.2µm pixels. Smaller pixels may require optical system adjustment to maintain equivalent light collection and signal-to-noise performance.

Q: Are both components RoHS compliant?

A: Yes. Both the KAF-8300-AXC-CP-AA and NOIX1SN8000B-LTI are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: What is the impact of the extended operating temperature range on the substitute part?

A: The NOIX1SN8000B-LTI operates from -40°C to 85°C, compared to the original -10°C to 70°C range. This extended range provides greater thermal operational flexibility for applications requiring wider temperature support.

Q: How does the moisture sensitivity level differ between these components?

A: The KAF-8300-AXC-CP-AA has MSL 1 (unlimited moisture exposure tolerance), while the NOIX1SN8000B-LTI has MSL 4 (72-hour moisture exposure limit). This affects storage, handling, and assembly procedures, requiring stricter moisture control for the substitute part.
