Key Parameters

Substitute Part Grouping Explanation

The SPEC Sensors 968-046 qualifies as a direct substitute for the 968-005 based on the following critical parameters:

• Sensor Type: Both components detect ozone (O3)
• Output Specification: Identical 0 V ~ 3 V analog voltage output
• Accuracy: Both maintain ±2% accuracy
• Supply Voltage: Both operate on 2.7V ~ 3.3V
• Supply Current: Both draw 15µA
• Regulatory Compliance: Both are ROHS3 compliant and carry EAR99 ECCN classification

The 968-046 is currently in active production status, providing long-term availability and supply chain continuity. The primary difference lies in the operating temperature range, where the 968-046 operates within -20°C ~ 40°C compared to the 968-005's -40°C ~ 50°C range.

Parameter Comparison

Engineering Selection Recommendations

The SPEC Sensors 968-046 is the direct substitute for the obsolete 968-005. Both components share identical electrical specifications for sensor type, output voltage, accuracy, supply requirements, and regulatory compliance status.

Selection of the 968-046 is appropriate for applications where the operating temperature range of -20°C ~ 40°C satisfies system requirements. Applications requiring operation below -20°C or above 40°C must evaluate alternative ozone sensor solutions, as the 968-046 does not extend to the full temperature envelope of the original 968-005.

The 968-046 maintains ROHS3 compliance and carries the same EAR99 export classification as the original component, ensuring regulatory continuity in system designs.

Frequently Asked Questions (FAQ)

Q: Can the 968-046 be used as a direct replacement for the 968-005 in all applications?

A: The 968-046 is electrically and functionally equivalent to the 968-005 for applications operating within the -20°C ~ 40°C temperature range. Applications requiring the extended -40°C ~ 50°C range of the original component require alternative solutions.

Q: What is the primary reason for substitution?

A: The 968-005 is classified as obsolete. The 968-046 is the active production equivalent from SPEC Sensors, ensuring continued availability and supply chain support.

Q: Are there any compliance differences between the two parts?

A: Both components are ROHS3 compliant and carry EAR99 ECCN classification. No compliance differences exist between the parts.

Q: What packaging is available for the 968-046?

A: The 968-046 is supplied in bulk packaging.

Q: Do the output characteristics differ between these sensors?

A: No. Both the 968-005 and 968-046 deliver identical 0 V ~ 3 V analog voltage output with ±2% accuracy and operate on 2.7V ~ 3.3V supply voltage at 15µA current draw.
