Substitute Part Grouping Explanation

The 968-047 qualifies as a direct substitute for the 968-004 based on identical electrical and functional parameters. Substitution is valid when the following criteria are met:

• Sensor type: Nitrogen Dioxide (NO2)
• Output voltage range: 0 V ~ 3 V
• Accuracy specification: ±2%
• Supply voltage range: 2.7V ~ 3.3V
• Supply current: 15µA
• Operating temperature range: -40°C ~ 50°C
• RoHS3 compliance requirement

The 968-047 maintains all specified electrical characteristics and environmental operating conditions, making it functionally interchangeable with the obsolete 968-004.

Parameter Comparison

Engineering Selection Recommendations

The 968-047 is the appropriate selection for applications currently using or requiring the 968-004. Both parts maintain identical electrical specifications, accuracy, and environmental operating parameters. The 968-047 is actively manufactured and stocked, providing supply chain reliability. Both components satisfy ROHS3 compliance and EAR99 export classification requirements. The 968-047 is available in bulk packaging and carries REACH Unaffected status with MSL 1 (Unlimited) moisture sensitivity rating, supporting standard handling and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the 968-047 directly replace the 968-004 in existing designs?

A: Yes. The 968-047 maintains identical electrical output (0 V ~ 3 V), accuracy (±2%), supply voltage (2.7V ~ 3.3V), supply current (15µA), and operating temperature range (-40°C ~ 50°C). No circuit modifications are required.

Q: What is the primary reason for substitution?

A: The 968-004 is classified as obsolete. The 968-047 is the active equivalent part from SPEC Sensors, ensuring continued availability and supply chain support.

Q: Are there compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant, carry EAR99 export classification, and share the same HTSUS code (9027.10.2000). The 968-047 additionally specifies REACH Unaffected status and MSL 1 moisture sensitivity.

Q: Does packaging differ between these parts?

A: The 968-004 packaging is not specified. The 968-047 is supplied in bulk packaging. Confirm packaging requirements for your application.

Q: Are there any performance differences?

A: No. Both sensors deliver identical NO2 detection performance, accuracy, and environmental operating specifications.
