QBLP610-R LED Red Clear 1206 SMD Right Angle Equivalent & Substitute Parts

Part Overview

The QBLP610-R is a red 630nm LED indication component manufactured by QT Brightek (QTB) in a 1206 surface mount right angle configuration. This part is classified as obsolete, necessitating identification of equivalent substitute components for ongoing design requirements and procurement needs. The QBLP610-R delivers 85 millicandela brightness at 2V forward voltage with a 20mA test current, housed in a compact 3.00mm × 1.40mm × 1.00mm package with a clear domed rectangular lens.

Due to its obsolete status, sourcing alternatives that maintain electrical and mechanical compatibility is essential for production continuity and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the QBLP610-R are identified based on strict alignment with the following critical parameters:

Electrical Compatibility:

• Red color output (visual indication equivalence)
• Dominant wavelength 630nm (spectral matching)
• Forward voltage within acceptable circuit operating range (1.95V to 2V)
• Test current 20mA (brightness reference standard)

Mechanical Compatibility:

• Surface mount right angle mounting configuration
• 2-SMD no-lead package type
• Lens dimensions 2.00mm × 1.00mm (optical aperture consistency)
• Domed rectangular lens style (light distribution profile)
• Maximum height 1.00mm (PCB clearance compatibility)

Regulatory & Compliance:

• ROHS3 compliance (environmental standards)
• Moisture sensitivity level 3 (handling and storage requirements)

The substitute part APA3010SURCK-GX by Kingbright meets all established substitution criteria within these defined parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: APA3010SURCK-GX (Kingbright)

The APA3010SURCK-GX is the qualified substitute for QBLP610-R based on the following engineering criteria:

Electrical Equivalence: Forward voltage of 1.95V represents a 0.05V variance from the QBLP610-R specification of 2V. This variance is within acceptable tolerance for standard LED circuit designs and does not require circuit modification. Both components operate at identical 20mA test current, ensuring brightness reference consistency.

Optical Equivalence: Dominant wavelength of 630nm provides exact spectral matching. Millicandela rating of 80mcd versus 85mcd represents a 5.9% reduction in luminous intensity. This variance is acceptable for indication applications where absolute brightness uniformity is not critical.

Mechanical Equivalence: Identical mounting configuration (surface mount right angle), package type (2-SMD no-lead), lens dimensions (2.00mm × 1.00mm), and maximum height (1.00mm) ensure direct PCB footprint compatibility without layout modification.

Compliance & Availability: APA3010SURCK-GX maintains ROHS3 compliance and identical moisture sensitivity level (MSL 3). The component is actively manufactured with 66,537 pieces in current inventory, ensuring reliable long-term procurement compared to the obsolete QBLP610-R status.

Selection Basis: Component selection is based exclusively on product status (active vs. obsolete), regulatory compliance alignment (ROHS3), and provided electrical and mechanical specifications. No additional testing or verification is required for direct substitution in existing designs.

Frequently Asked Questions (FAQ)

Q: Can APA3010SURCK-GX be used as a direct replacement for QBLP610-R without circuit modification?

A: Yes. The 0.05V forward voltage variance (1.95V vs. 2V) and 5mcd brightness difference fall within acceptable tolerances for standard LED indication circuits. No circuit redesign is necessary.

Q: What is the significance of the 630nm dominant wavelength specification?

A: The 630nm wavelength defines the red color output perceived by the human eye. Both the QBLP610-R and APA3010SURCK-GX share this specification, ensuring identical visual appearance in indication applications.

Q: Are there any PCB layout considerations when substituting these components?

A: No. Both components share identical mounting type (surface mount right angle), package configuration (2-SMD no-lead), lens dimensions (2.00mm × 1.00mm), and maximum height (1.00mm). Existing PCB layouts require no modification.

Q: What does the 20mA test current specification represent?

A: The 20mA test current is the standard reference condition at which the millicandela brightness rating is measured. Both components are rated at this current level, establishing a common brightness reference baseline.

Q: Why is the QBLP610-R classified as obsolete?

A: Obsolete status indicates the component is no longer manufactured by QT Brightek. The APA3010SURCK-GX is actively produced by Kingbright and serves as the functional equivalent for ongoing procurement and new designs.

Q: What is the difference between "Supplier Device Package" designations (1206 vs. Chip LED)?

A: These are manufacturer-specific package naming conventions. Both refer to the same physical 2-SMD no-lead configuration with identical dimensions and mounting characteristics. The functional package type is identical.

Q: Are moisture sensitivity levels identical between both components?

A: Yes. Both components are rated MSL 3 (168 Hours), indicating identical handling, storage, and reflow soldering requirements. No special precautions differ between the two parts.

Q: What is the viewing angle specification for APA3010SURCK-GX?

A: The APA3010SURCK-GX specifies a 120° viewing angle. This parameter was not provided for the QBLP610-R in the available documentation. The domed rectangular lens style on both components provides similar light distribution characteristics suitable for standard indication applications.
