QBLP650-S1 LED Red Clear 1206 SMD Equivalent & Substitute Parts

Part Overview

The QBLP650-S1 is a red 640nm LED indication component in 1206 (3216 Metric) surface mount package configuration. This discrete 2V LED is designed for standard indication applications with a 13mcd brightness rating and clear colorless lens. The QBLP650-S1 is classified as obsolete product status, making identification of equivalent and substitute parts essential for ongoing design support, production continuity, and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the QBLP650-S1 is determined by strict alignment of the following critical parameters:

Mechanical Compatibility:

• Package type: 1206 (3216 Metric) surface mount
• Physical dimensions: 3.20mm L x 1.60mm W x 1.20mm H (Max)
• Lens style: Rectangle with Flat Top
• Lens size: 2.00mm x 1.60mm

Electrical Compatibility:

• Color: Red
• Wavelength - Dominant: 640nm
• Voltage - Forward (Vf): 2V nominal
• Current - Test: 20mA

Regulatory & Environmental Compliance:

• RoHS3 Compliant
• REACH Unaffected
• Moisture Sensitivity Level: 3 (168 Hours)

The QBLP650-S3 qualifies as a direct substitute based on identical mechanical package specifications, matching forward voltage, test current, dominant wavelength, and regulatory compliance status. The QBLP650-S3 maintains active product status and is available in standard packaging configurations.

Parameter Comparison

Engineering Selection Recommendations

The QBLP650-S3 is the direct substitute for the obsolete QBLP650-S1. Both components share identical mechanical package specifications (1206 surface mount), electrical characteristics (2V forward voltage, 20mA test current), and regulatory compliance status (ROHS3 Compliant, REACH Unaffected, MSL 3).

The QBLP650-S3 maintains active product status with higher inventory availability and standard packaging options (Cut Tape and Tape & Reel configurations). The substitute part exhibits increased brightness output (25mcd versus 13mcd) and provides specified viewing angle performance (140°), which represents an enhancement over the obsolete reference part.

Both components are manufactured by QT Brightek within the same QBLP650 series, ensuring design continuity and manufacturing consistency. The QBLP650-S3 is suitable for direct replacement in applications requiring red 640nm LED indication in 1206 surface mount configuration.

Frequently Asked Questions (FAQ)

Q: Can the QBLP650-S3 be used as a direct replacement for the QBLP650-S1?

A: Yes. The QBLP650-S3 is a direct substitute. Both components share identical package specifications (1206 surface mount), physical dimensions (3.20mm L x 1.60mm W x 1.20mm H), forward voltage (2V), test current (20mA), dominant wavelength (640nm), and regulatory compliance status (ROHS3 Compliant, REACH Unaffected, MSL 3).

Q: What are the differences between QBLP650-S1 and QBLP650-S3?

A: The primary differences are product status and brightness output. The QBLP650-S1 is obsolete with 13mcd brightness, while the QBLP650-S3 is active with 25mcd brightness. The QBLP650-S3 also specifies a 140° viewing angle and 660nm peak wavelength, whereas the QBLP650-S1 does not provide these specifications.

Q: Are the mechanical packages identical between these parts?

A: Yes. Both components use the 1206 (3216 Metric) surface mount package with identical dimensions: 3.20mm length, 1.60mm width, and 1.20mm maximum height. Lens specifications are also identical: Rectangle with Flat Top style, 2.00mm x 1.60mm lens size, colorless lens color, and clear transparency.

Q: What packaging options are available for the QBLP650-S3?

A: The QBLP650-S3 is available in Cut Tape (CT) and Digi-Reel® packaging, as well as standard Tape & Reel (TR) configuration.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the QBLP650-S1 and QBLP650-S3 are ROHS3 Compliant and REACH Unaffected. Both components have Moisture Sensitivity Level 3 (168 Hours).

Q: Will the increased brightness of the QBLP650-S3 affect circuit design?

A: The QBLP650-S3 operates at identical forward voltage (2V) and test current (20mA) as the QBLP650-S1. The increased brightness output (25mcd versus 13mcd) results from improved LED die efficiency within the same electrical operating parameters. Existing circuit designs require no modification for substitution.
