Key Parameters

Substitute Part Grouping Explanation

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

Sensor Technology & Resolution: The main part uses CCD technology with 8.3MP resolution (3326H x 2504V). Substitute parts must deliver equivalent or superior imaging capability in terms of total pixel count and active array dimensions.

Pixel Geometry: The 5.4µm x 5.4µm pixel size defines the sensor's light-gathering capability and noise characteristics. Substitutes with different pixel dimensions represent a fundamental change in optical performance.

Supply Voltage Requirements: The 14.5V to 15.5V supply voltage is specific to CCD sensor operation. CMOS alternatives operate at significantly lower voltages (1.7V to 2.9V), requiring circuit redesign.

Package Configuration: The 32-CDIP module package constrains physical integration. Substitutes with different package types (such as 163-CLGA) require PCB layout modifications.

Operating Temperature Range: The -10°C to 70°C specification defines the thermal operating envelope. Substitutes must meet or exceed this range for equivalent environmental compatibility.

Compliance & Availability: RoHS3 compliance and product status (active vs. obsolete) are essential for supply chain continuity and regulatory adherence.

Engineering Selection Recommendations

NOIX1SN8000B-LTI Substitution Considerations

The NOIX1SN8000B-LTI is an active-status CMOS image sensor from onsemi that provides higher resolution (4096H x 2160V) compared to the KAF-8300-AXC-CB-AA. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

Critical Differences Requiring Design Evaluation

The substitution involves a transition from CCD to CMOS technology, which introduces fundamental differences:

Supply voltage reduction from 14.5V–15.5V to 1.7V–1.9V and 2.7V–2.9V necessitates complete power delivery circuit redesign. Pixel size reduction from 5.4µm to 3.2µm alters optical performance characteristics and requires optical system recalibration. Package change from 32-CDIP to 163-BCLGA demands PCB layout modification. Operating temperature range expansion (-40°C to 85°C) provides improved thermal coverage. Frame rate capability (128 fps) introduces dynamic performance not specified in the original part.

Compliance & Supply Chain

The NOIX1SN8000B-LTI maintains active product status, ensuring long-term availability and supply chain stability. MSL rating of 4 (72 hours) requires controlled moisture handling during assembly, compared to the unlimited MSL of the original part.

Frequently Asked Questions (FAQ)

Q: Can the NOIX1SN8000B-LTI directly replace the KAF-8300-AXC-CB-AA without circuit modifications?

A: No. The voltage supply requirements differ fundamentally (14.5V–15.5V vs. 1.7V–1.9V and 2.7V–2.9V), and the package types are incompatible (32-CDIP vs. 163-BCLGA). Complete power delivery and PCB layout redesign is required.

Q: What are the key differences in imaging performance between these sensors?

A: The KAF-8300-AXC-CB-AA uses CCD technology with 5.4µm pixels, while the NOIX1SN8000B-LTI uses CMOS technology with 3.2µm pixels. The CMOS sensor provides higher resolution (4096H x 2160V vs. 3326H x 2504V) and frame rate capability (128 fps), but pixel size reduction affects light-gathering characteristics and requires optical system recalibration.

Q: Are both components RoHS compliant?

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

Q: What is the impact of the MSL rating difference?

A: The KAF-8300-AXC-CB-AA has MSL 1 (unlimited moisture sensitivity level), while the NOIX1SN8000B-LTI has MSL 4 (72-hour limit). The substitute part requires controlled moisture handling during storage and assembly to prevent component degradation.

Q: Does the NOIX1SN8000B-LTI offer improved operating temperature coverage?

A: Yes. The NOIX1SN8000B-LTI operates from -40°C to 85°C (TJ), compared to -10°C to 70°C (TA) for the original part, providing expanded thermal operating range.

Q: What is the inventory status of these components?

A: The KAF-8300-AXC-CB-AA (1054 pcs) is obsolete but currently in stock. The NOIX1SN8000B-LTI (1033 pcs) is active status with ongoing availability.
