QBLP610-IB LED Blue Clear 1206 SMD Right Angle Equivalent & Substitute Parts

Part Overview

The QBLP610-IB is a blue 470nm LED indication component manufactured by QT Brightek (QTB), designed for surface mount right angle applications in the 1206 package format. This part features a clear colorless lens with a domed rectangular top, rated at 100 millicandela with a forward voltage of 3.1V at 20mA test current.

The QBLP610-IB is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this LED specification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the QBLP610-IB are identified based on strict alignment of the following critical parameters:

Color and Wavelength Compatibility: The substitute must emit blue light at the dominant wavelength of 470nm to maintain optical consistency in indication applications.

Lens Configuration: The substitute must feature a colorless clear lens with a rectangular domed top geometry to ensure consistent light distribution and visual appearance.

Electrical Characteristics: Forward voltage and test current specifications determine circuit compatibility. The substitute forward voltage of 3.3V (APA3010QBC/D) represents a 0.2V variance from the original 3.1V specification, which is acceptable within standard LED tolerance ranges for indication applications.

Mounting and Package: Surface mount right angle mounting type and 2-SMD no-lead package configuration are required to maintain PCB assembly compatibility.

Regulatory Compliance: RoHS3 compliance and MSL rating of 3 (168 Hours) must be maintained to ensure manufacturing process compatibility and environmental regulation adherence.

Millicandela Rating: The substitute part rated at 90mcd operates within acceptable brightness parameters for indication applications, representing a 10% reduction from the original 100mcd specification.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: The APA3010QBC/D from Kingbright is qualified as a direct substitute for the obsolete QBLP610-IB based on the following engineering criteria:

Compliance Alignment: Both parts maintain ROHS3 compliance and identical MSL ratings of 3 (168 Hours), ensuring compatibility with current manufacturing processes and environmental regulations.

Optical Specifications: Dominant wavelength alignment at 470nm with matching lens configuration (colorless clear rectangular domed top) ensures consistent optical performance in indication applications.

Electrical Compatibility: The forward voltage differential of 0.2V (3.1V to 3.3V) falls within standard LED tolerance ranges and does not require circuit redesign for typical indication applications operating at 20mA test current.

Mechanical Fit: Identical mounting type (surface mount right angle), package configuration (2-SMD no lead), and height specification (1.00mm maximum) ensure direct PCB assembly compatibility. The width variance (1.40mm to 2.00mm) represents a 0.6mm increase and must be evaluated against available PCB footprint space.

Supply Continuity: The APA3010QBC/D maintains active product status with higher inventory availability (2200 pcs) compared to the obsolete QBLP610-IB, supporting long-term supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can the APA3010QBC/D directly replace the QBLP610-IB without circuit modifications?

A: The APA3010QBC/D is electrically compatible for indication applications. The forward voltage increase from 3.1V to 3.3V is within standard LED tolerance ranges. However, circuit evaluation is required if the original design operates at voltage margins below 3.3V or if precise current limiting is critical to application performance.

Q: What is the significance of the 10mcd brightness difference between the two parts?

A: The QBLP610-IB is rated at 100mcd while the APA3010QBC/D is rated at 90mcd. This 10% reduction in luminous intensity may be acceptable for indication applications where brightness is not a critical parameter. Applications requiring specific brightness levels must evaluate whether 90mcd meets functional requirements.

Q: Does the width dimension change from 1.40mm to 2.00mm affect PCB assembly?

A: The 0.6mm width increase must be verified against the PCB footprint design. If the original footprint was designed with minimal clearance margins, the wider component may require footprint modification. Standard PCB design practices typically accommodate this variance, but layout review is necessary.

Q: Are there any differences in viewing angle between these parts?

A: The QBLP610-IB does not specify a viewing angle parameter. The APA3010QBC/D specifies 120° viewing angle. This specification difference does not indicate incompatibility; it reflects available technical documentation. Both parts feature identical lens geometry (rectangle with domed top) designed for right angle mounting applications.

Q: What is the impact of the packaging format change from individual to Tape & Reel?

A: The QBLP610-IB is supplied in standard packaging format, while the APA3010QBC/D is supplied in Tape & Reel (TR) format. This affects procurement and assembly processes but does not impact component functionality or electrical performance. Tape & Reel packaging is standard for high-volume surface mount assembly operations.

Q: Are both parts suitable for the same environmental and regulatory applications?

A: Yes. Both parts maintain ROHS3 compliance, identical MSL ratings (3, 168 Hours), and equivalent regulatory classifications (ECCN: EAR99, HTSUS: 8541.41.0000). They are suitable for equivalent environmental and regulatory applications.
