Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 110-401 is determined by the following critical parameters:

• Sensor Type: Must detect Ozone (O3)
• Operating Temperature Range: Must support -30°C to 50°C minimum
• RoHS Compliance: Must maintain ROHS3 Compliant status
• Manufacturer: SPEC Sensors (Interlink Electronics) product line
• ECCN/Export Classification: Must align with EAR99 classification
• HTSUS Commodity Code: Must match 9027.10.2000 (Gas analysis instruments)

The 110-406 qualifies as a substitute based on matching sensor type (Ozone O3), identical operating temperature range (-30°C to 50°C), equivalent RoHS3 compliance, and shared manufacturer origin. The primary distinction is packaging format and product status transition from obsolete to active.

Parameter Comparison

Engineering Selection Recommendations

The 110-406 is the designated substitute for the obsolete 110-401. Both components maintain identical compliance certifications (ROHS3, EAR99) and operate within the same temperature envelope. The 110-406 carries active product status, ensuring ongoing manufacturer support and availability. Selection of the 110-406 eliminates obsolescence risk while preserving functional and regulatory equivalence. Packaging format differs (Tray for 110-406 versus unspecified for 110-401), requiring verification of mechanical integration requirements in the target application.

Frequently Asked Questions (FAQ)

Q: Can the 110-406 directly replace the 110-401 in existing designs?

A: The 110-406 matches all critical electrical and environmental parameters (sensor type, temperature range, accuracy class, compliance status). Mechanical compatibility depends on packaging and form factor differences. Physical integration verification is required before implementation.

Q: What is the primary reason for substitution?

A: The 110-401 is classified as obsolete. The 110-406 is an active product from the same manufacturer with equivalent functional specifications, ensuring long-term availability and support.

Q: Are there compliance differences between these parts?

A: No. Both components are ROHS3 compliant, carry EAR99 export classification, and share the same HTSUS commodity code (9027.10.2000). Regulatory requirements are identical.

Q: How do the output specifications compare?

A: The 110-401 specifies current output with ±3% accuracy. The 110-406 output type is not specified in available documentation. Detailed electrical characterization of the 110-406 output stage is required to confirm functional equivalence.

Q: What is the moisture sensitivity implication?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling. Standard component storage practices apply.
