Key Parameters

Substitute Part Grouping Explanation

Substitution of the LO E6SF-BBCB-34-1-50-R18-Z is based on the following critical parameters that must align across components:

Wavelength Compatibility: Both the main part and substitute maintain identical dominant (606nm) and peak (610nm) wavelengths, ensuring color consistency in indication applications.

Optical Properties: Both components feature colorless lens material with clear transparency and 120° viewing angle, maintaining equivalent light distribution characteristics.

Electrical Characteristics: Forward voltage and test current specifications determine circuit compatibility. The substitute operates at 2.3V forward voltage with 20mA test current, requiring circuit design evaluation for applications with fixed current-limiting resistor networks.

Surface Mount Technology: Both components utilize surface mount assembly methods, compatible with standard PCB manufacturing processes.

Wavelength-Specific Certification: Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, confirming regulatory equivalence for orange 606nm LED indication devices.

The substitute part KO DELPS1.22-UGVI-24-H3Q4-20-S represents an active production alternative within the ams-OSRAM TOPLED® product family, with current inventory availability and RoHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The LO E6SF-BBCB-34-1-50-R18-Z carries Last Time Buy status, indicating end-of-life production. The substitute KO DELPS1.22-UGVI-24-H3Q4-20-S maintains Active product status with current manufacturing availability, supporting long-term supply chain continuity.

Compliance and Certification: Both components share identical ECCN and HTSUS classifications, confirming regulatory equivalence. The substitute part carries RoHS3 compliance certification and REACH Unaffected status, meeting current environmental and chemical restriction requirements. Moisture Sensitivity Level (MSL) rating of 2 (1 Year) for the substitute indicates standard handling and storage requirements for surface mount assembly.

Electrical Parameter Differences: Circuit design modifications are required when substituting these components. The forward voltage increase from 2.15V to 2.3V and test current reduction from 50mA to 20mA necessitate recalculation of current-limiting resistor values to maintain proper LED operation within specified parameters.

Package Transition: The shift from 4-PLCC to 2-SMD flat lead package requires PCB layout modification. The substitute component features significantly reduced dimensions (1.40mm L x 0.80mm W x 0.70mm H maximum) compared to the original (3.20mm L x 2.80mm W x 2.10mm H maximum), enabling higher component density in redesigned layouts.

Optical Equivalence: Identical wavelength specifications and viewing angle characteristics ensure color consistency and light distribution properties remain unchanged in indication applications.

Frequently Asked Questions (FAQ)

Q: Can the KO DELPS1.22-UGVI-24-H3Q4-20-S directly replace the LO E6SF-BBCB-34-1-50-R18-Z without circuit modification?

A: No. While both components share identical wavelength and optical properties, the forward voltage difference (2.15V to 2.3V) and test current difference (50mA to 20mA) require recalculation of current-limiting resistor values. Direct substitution without circuit adjustment will result in incorrect LED operating current and potential brightness variation.

Q: What are the primary differences between these two LED components?

A: The main differences are package type (4-PLCC versus 2-SMD flat lead), physical dimensions (larger original versus significantly smaller substitute), forward voltage (2.15V versus 2.3V), and test current (50mA versus 20mA). Both maintain identical wavelength specifications (606nm dominant, 610nm peak) and optical characteristics (120° viewing angle, clear colorless lens).

Q: Is the substitute part suitable for new design applications?

A: Yes. The KO DELPS1.22-UGVI-24-H3Q4-20-S carries Active product status with current manufacturing availability, RoHS3 compliance, and REACH compliance, making it suitable for new designs. The original part's Last Time Buy status makes it unsuitable for new applications requiring long-term component availability.

Q: What PCB design changes are necessary when switching to the substitute component?

A: The substitute component requires new PCB footprint design due to package type change from 4-PLCC to 2-SMD flat lead. The significantly smaller dimensions (1.40mm x 0.80mm versus 3.20mm x 2.80mm) allow for higher component density. Current-limiting resistor values must be recalculated based on the new forward voltage (2.3V) and test current (20mA) specifications.

Q: Are both components from the same manufacturer?

A: Yes. Both the LO E6SF-BBCB-34-1-50-R18-Z and KO DELPS1.22-UGVI-24-H3Q4-20-S are manufactured by ams-OSRAM USA INC., ensuring consistent quality standards and technical support.

Q: What is the Moisture Sensitivity Level (MSL) for the substitute component?

A: The KO DELPS1.22-UGVI-24-H3Q4-20-S carries MSL rating of 2 (1 Year), indicating standard moisture sensitivity handling requirements. Components must be stored in controlled humidity environments and used within one year of package opening per IPC-A-113 standards.

Q: Do both components have identical regulatory classifications?

A: Yes. Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, confirming regulatory equivalence for orange 606nm LED indication devices.
