Key Parameters

Substitute Part Grouping Explanation

Substitution of the QBLP610-AG is determined by strict alignment of the following electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Color: Green (570nm dominant wavelength)
• Forward Voltage (Vf): 2V nominal operation
• Current Rating: 20mA test current
• Brightness: 50mcd millicandela rating

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount, Right Angle configuration
• Lens Style: Rectangle with Domed Top
• Lens Size: 2.00mm x 1.00mm
• Package Type: 2-SMD, No Lead
• Height: 1.00mm maximum

Regulatory & Environmental Criteria:

• RoHS3 Compliance
• REACH Unaffected status
• Moisture Sensitivity Level compatibility

The CMD12-21VGC/TR8 qualifies as a substitute based on matching color, wavelength, mounting configuration, lens geometry, and regulatory compliance. Variations in forward voltage (2.1V vs 2V), millicandela rating (8.8mcd vs 50mcd), and physical width (2.00mm vs 1.40mm) represent acceptable parameter ranges within the 2-SMD right angle green LED category.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The QBLP610-AG carries obsolete product status, making the CMD12-21VGC/TR8 the appropriate selection for new designs and ongoing procurement. The CMD12-21VGC/TR8 maintains active product status with confirmed inventory availability (8126 Pcs).

Regulatory Compliance: Both components satisfy ROHS3 compliance and REACH unaffected requirements, ensuring regulatory alignment for current manufacturing standards.

Moisture Sensitivity: The CMD12-21VGC/TR8 provides improved moisture sensitivity rating (MSL 2, 1 Year) compared to the QBLP610-AG (MSL 3, 168 Hours), offering enhanced storage and handling flexibility.

Packaging Format: The CMD12-21VGC/TR8 is supplied in Tape & Reel format, supporting automated assembly processes. The QBLP610-AG bulk packaging is no longer available due to obsolete status.

Electrical Parameter Variance: Forward voltage increases from 2V to 2.1V, requiring circuit verification for voltage-sensitive applications. Millicandela rating decreases from 50mcd to 8.8mcd, necessitating brightness assessment for visibility-critical indicator applications.

Frequently Asked Questions (FAQ)

Q: Can the CMD12-21VGC/TR8 directly replace the QBLP610-AG in existing PCB designs?

A: Physical compatibility is confirmed for mounting footprint and height (1.00mm maximum). Circuit design review is required to validate the 0.1V forward voltage increase (2V to 2.1V) and 41.2mcd brightness reduction (50mcd to 8.8mcd) within application requirements.

Q: What are the key differences between these two parts?

A: Primary differences include manufacturer (QTB vs VCC), product status (obsolete vs active), forward voltage (2V vs 2.1V), brightness rating (50mcd vs 8.8mcd), physical width (1.40mm vs 2.00mm), moisture sensitivity (MSL 3 vs MSL 2), and packaging format (bulk vs Tape & Reel).

Q: Is the brightness difference significant for indicator applications?

A: The CMD12-21VGC/TR8 provides 8.8mcd versus the QBLP610-AG's 50mcd. Application-specific brightness requirements must be evaluated. For low-brightness indicator applications, the CMD12-21VGC/TR8 is suitable. For high-visibility requirements, alternative parts with higher millicandela ratings should be considered.

Q: Does the forward voltage increase affect circuit design?

A: The 0.1V increase (2V to 2.1V) is within typical LED tolerance ranges. Current-limiting resistor values may require minor adjustment to maintain 20mA test current. Circuit simulation or bench testing is recommended for precision applications.

Q: What is the viewing angle specification for the CMD12-21VGC/TR8?

A: The CMD12-21VGC/TR8 specifies 120° viewing angle. The QBLP610-AG viewing angle is not provided in available documentation.

Q: Are both parts suitable for automated assembly?

A: The CMD12-21VGC/TR8 is supplied in Tape & Reel format, supporting automated pick-and-place assembly. The QBLP610-AG bulk packaging is obsolete and no longer available for new procurement.

Q: What is the wavelength specification for both parts?

A: Both components operate at 570nm green wavelength. The QBLP610-AG specifies 570nm dominant wavelength. The CMD12-21VGC/TR8 specifies 570nm peak wavelength.

Q: Are there any storage or handling differences between these parts?

A: The CMD12-21VGC/TR8 offers superior moisture sensitivity (MSL 2, 1 Year shelf life) compared to the QBLP610-AG (MSL 3, 168 Hours). The improved MSL rating provides extended storage capability and reduced risk of moisture-induced failures.
