Substitute Part Grouping Explanation

Substitution of the QLR343BC4T3FXM is based on the following criteria derived from provided parameters:

Primary Substitution Criteria:

• Identical manufacturer (Rohm Semiconductor)
• Identical component category (LED Indication - Discrete)
• Identical package classification (SMD)
• Matching RoHS compliance level (ROHS3 Compliant)
• Matching ECCN and HTSUS classifications

The substitute part QLR343BN4TT32 satisfies all substitution parameters. The key differentiator is product status: the substitute maintains active status, ensuring continued availability and manufacturer support, whereas the main part is obsolete.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Ongoing Production:

The QLR343BN4TT32 is the appropriate selection for applications currently using or specifying the QLR343BC4T3FXM. Both components share identical functional classification, package type, and compliance certifications. The substitute part carries active product status, ensuring manufacturer support, continued availability, and compliance documentation throughout the component lifecycle.

Compliance Alignment:

Both parts maintain ROHS3 compliance and EAR99 export classification, supporting equivalent regulatory and supply chain requirements. The substitute part provides additional documentation through explicit MSL rating (1 - Unlimited) and REACH status confirmation, enhancing traceability for regulated applications.

Inventory Considerations:

Current stock availability exists for both components. The main part inventory (835 Pcs) supports existing stock-down requirements, while the substitute part inventory (680 Pcs) supports transition to active component sourcing.

Frequently Asked Questions (FAQ)

Q: Can QLR343BN4TT32 directly replace QLR343BC4T3FXM in existing designs?

A: Yes. Both components are discrete LED indication SMD devices from Rohm Semiconductor with identical package classification and RoHS compliance status. The substitute maintains all specified electrical and mechanical parameters within the provided documentation.

Q: Why is the main part listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support for QLR343BC4T3FXM. The substitute part QLR343BN4TT32 maintains active status with ongoing manufacturer support.

Q: What is the significance of MSL rating 1 (Unlimited) on the substitute part?

A: MSL (Moisture Sensitivity Level) 1 indicates the component has unlimited shelf life without moisture control requirements, providing simplified storage and handling procedures compared to higher MSL ratings.

Q: Are there any export or regulatory differences between these parts?

A: No. Both components carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, indicating equivalent export control and tariff treatment.

Q: Is the substitute part REACH compliant?

A: The substitute part QLR343BN4TT32 carries REACH Unaffected status, confirming compliance with REACH regulations. The main part documentation does not specify REACH status.
