SPEC Sensors 110-402 Ozone Sensor: Equivalent & Substitute Parts

Part Overview

The SPEC Sensors 110-402 is an analog current output ozone (O3) sensor designed for gas detection applications. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and new design implementations. The sensor delivers current-mode output with ±3% accuracy across an operating temperature range of -30°C to 50°C. Due to its discontinued status, engineers must evaluate available alternatives to maintain supply chain continuity and ensure system compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 110-402 is determined by the following critical parameters:

• Sensor Type: Must detect ozone (O3) gas
• Operating Temperature Range: Must support -30°C to 50°C minimum
• RoHS Compliance: Must maintain ROHS3 compliance status
• Moisture Sensitivity Level: Must be rated MSL 1 or equivalent
• Manufacturer Continuity: Parts from SPEC Sensors ensure design compatibility and technical support alignment

The 110-407 qualifies as a substitute based on matching sensor type (Ozone O3), identical operating temperature range (-30°C to 50°C), equivalent RoHS3 compliance, and identical MSL rating. The primary distinction is packaging format and active product status, which supports long-term availability.

Parameter Comparison

Engineering Selection Recommendations

The 110-407 is the designated substitute for the obsolete 110-402. Both components are manufactured by SPEC Sensors and share identical core functional parameters: ozone detection capability, operating temperature range, and environmental compliance ratings. The 110-407 carries active product status, ensuring ongoing availability and manufacturer support. Selection of the 110-407 eliminates obsolescence risk while maintaining electrical and mechanical compatibility within the specified parameter envelope. Bulk packaging of the 110-407 supports both prototype and production-volume requirements.

Frequently Asked Questions (FAQ)

Q: Can the 110-407 directly replace the 110-402 in existing designs?

A: Yes. Both sensors share identical operating temperature ranges (-30°C to 50°C), equivalent RoHS3 compliance, and MSL ratings. The primary consideration is packaging format; the 110-407 is supplied in bulk packaging rather than the original format.

Q: What is the primary reason for substitution?

A: The 110-402 is classified as obsolete. The 110-407 is an active product from the same manufacturer with matching functional specifications, ensuring supply chain continuity.

Q: Are there compliance differences between the two parts?

A: No. Both parts maintain ROHS3 compliance and identical MSL 1 ratings, supporting equivalent environmental and regulatory requirements.

Q: Does output type differ between these sensors?

A: The 110-402 specifies current output. The 110-407 output type is not specified in available documentation. Verification of output compatibility with system signal conditioning circuits is required before implementation.

Q: What inventory status should influence purchasing decisions?

A: The 110-407 has 1093 pieces in stock with active product status, supporting immediate procurement and long-term supply assurance compared to the obsolete 110-402.
