Key Parameters

Substitute Part Grouping Explanation

Substitution of the AXUV100 is based on strict equivalence across the following critical parameters:

Wavelength Matching: Both the main part and substitute must operate at 254nm to maintain spectral response characteristics.

Active Area Equivalence: The 100mm² active area must be preserved to ensure consistent light collection and sensor responsiveness.

Reverse Voltage Rating: Maximum DC reverse voltage of 10V establishes the electrical operating envelope.

Operating Temperature Range: The -10°C to 40°C range defines the thermal operating window.

Mounting Configuration: Through-hole mounting type ensures mechanical compatibility with existing PCB designs.

Moisture Sensitivity Classification: MSL 1 (Unlimited) indicates no moisture-related handling restrictions.

The AXUV100G qualifies as a direct substitute based on these parameters. Both components share identical wavelength, active area, reverse voltage rating, operating temperature range, mounting type, and moisture sensitivity classification.

Parameter Comparison

Engineering Selection Recommendations

AXUV100G as Primary Substitute: The AXUV100G is the direct equivalent for AXUV100 applications. Both components are manufactured by Opto Diode Corp within the AXUV series and share identical critical specifications across wavelength, active area, voltage rating, temperature range, and mounting configuration.

Product Status Advantage: The AXUV100G maintains active product status with confirmed inventory availability (1069 pieces), whereas the AXUV100 is obsolete. This status difference ensures long-term supply chain viability and continued manufacturer support.

Compliance Alignment: Both parts carry identical ECCN (EAR99) and HTSUS (8541.49.1050) classifications, confirming regulatory and trade compliance equivalence.

RoHS Compliance: The AXUV100G is explicitly RoHS Compliant, providing environmental and regulatory assurance for applications subject to RoHS requirements.

Frequently Asked Questions (FAQ)

Q: Can AXUV100G directly replace AXUV100 in existing designs?

A: Yes. The AXUV100G is a direct substitute. Both components share identical wavelength (254nm), active area (100mm²), reverse voltage rating (10V), operating temperature range (-10°C to 40°C), and through-hole mounting configuration. No circuit modifications are required.

Q: What is the primary reason to switch from AXUV100 to AXUV100G?

A: The AXUV100 is classified as obsolete, while AXUV100G maintains active product status. Transitioning to AXUV100G ensures continued availability, manufacturer support, and supply chain reliability.

Q: Are there packaging differences between AXUV100 and AXUV100G?

A: The AXUV100G is supplied in Bulk packaging, whereas packaging information for AXUV100 is not specified in the provided data. Both components use through-hole mounting, ensuring mechanical compatibility with standard PCB designs.

Q: Do both parts have the same moisture sensitivity requirements?

A: Yes. Both AXUV100 and AXUV100G are classified as MSL 1 (Unlimited), indicating no moisture-related handling or storage restrictions.

Q: Are export and trade classifications identical?

A: Yes. Both components share the same ECCN (EAR99) and HTSUS (8541.49.1050) classifications, confirming equivalent regulatory treatment for export and trade purposes.

Q: What is the difference in dark current between the two parts?

A: The AXUV100 dark current specification is not provided. The AXUV100G specifies a typical dark current of 2nA. This parameter does not affect substitution eligibility but may be relevant for low-light signal processing applications.
