Key Parameters

Substitute Part Grouping Explanation

The SIR-34ST3F is identified as the manufacturer-recommended substitute for the SIR-320ST3F. Substitution compatibility is determined by the following parameters:

Compliance and Regulatory Alignment:

• RoHS3 Compliance status
• REACH Unaffected designation
• ECCN classification (EAR99)
• HTSUS tariff code (8541.41.0000)

Functional Classification:

• Component type: Infrared (IR) Emitter
• Manufacturer: Rohm Semiconductor
• Base product family alignment

The SIR-34ST3F maintains identical regulatory compliance, export classification, and tariff coding, establishing it as a direct substitute within the Rohm Semiconductor infrared emitter product line.

Parameter Comparison

Engineering Selection Recommendations

Regulatory Compliance Basis:

Both the SIR-320ST3F and SIR-34ST3F maintain identical regulatory compliance profiles:

• ROHS3 Compliant status ensures conformance to Restriction of Hazardous Substances requirements
• REACH Unaffected designation confirms no SVHC (Substances of Very High Concern) restrictions
• EAR99 export classification and 8541.41.0000 HTSUS code alignment enable consistent supply chain management

Product Status Consideration:

Both components are designated as Obsolete. The SIR-34ST3F, with 3660 units in current inventory compared to 695 units of the SIR-320ST3F, provides superior availability for immediate procurement and long-term supply continuity.

Substitution Validity:

The SIR-34ST3F is the manufacturer-recommended substitute, confirmed by Rohm Semiconductor's official substitution designation. Selection of this substitute maintains regulatory compliance, export classification consistency, and component family alignment.
