Substitute Part Grouping Explanation

The 1SE1-2 is identified as a direct substitute for the 1SE112 based on the following substitution criteria:

Manufacturer Continuity: Both parts are manufactured by Honeywell Sensing and Productivity Solutions, ensuring design lineage and technical support consistency.

Compliance Alignment: Both parts maintain RoHS Compliant status and identical Moisture Sensitivity Level (MSL 1 - Unlimited), confirming environmental and regulatory compatibility.

Export Classification: Both parts share the same ECCN classification (EAR99), indicating no change in export control requirements.

Product Category: Both are classified as snap action switches within the Honeywell switch product family, with the 1SE1-2 representing the active series continuation (SE series).

Electrical Specifications: The 1SE1-2 provides defined electrical parameters (SPDT circuit, 5A at 250V AC, 30V DC) suitable for applications previously served by the 1SE112.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement: The 1SE1-2 is the designated active substitute for the obsolete 1SE112. Both parts maintain identical RoHS compliance and MSL ratings, ensuring regulatory and environmental requirement continuity.

For New Designs: The 1SE1-2 should be selected as the primary component choice. This part carries active product status with defined electrical and mechanical specifications, providing long-term supply chain stability and technical support from Honeywell Sensing and Productivity Solutions.

For Compliance-Critical Applications: Both parts share identical ECCN classification (EAR99) and RoHS status, confirming that substitution does not introduce compliance complications for export or environmental regulations.

Inventory Considerations: The 1SE112 maintains 1015 units in stock as new original inventory. The 1SE1-2 maintains 743 units in stock. Component selection should account for current project timelines and long-term supply requirements.
