• Efficiency: 131 lm/W
• CRI: 65

Mechanical Parameters:

• Package type: 2020 (5050 metric)
• Mounting type: Surface mount
• Viewing angle: 120°
• Physical dimensions: 0.197" L x 0.197" W (5.00mm x 5.00mm)
• Maximum seated height: 0.115" (2.92mm)
• Thermal resistance: 0.6°C/W

Compliance Parameters:

• RoHS3 compliance

The identified substitute parts SST-70X-WCS-H50-KA651 and SST-70X-WCS-H50-KA652 maintain identical electrical and mechanical specifications. Differences exist only in packaging format (Cut Tape versus Digi-Reel) and moisture sensitivity level (MSL), which do not affect functional performance in equivalent applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SST-70X-WCS-H50-JB652, SST-70X-WCS-H50-KA651, and SST-70X-WCS-H50-KA652—are classified as obsolete products. Selection among these equivalents is based on packaging and handling requirements rather than functional performance.

SST-70X-WCS-H50-JB652 (Digi-Reel® Packaging, MSL 1): Suitable for applications requiring unlimited shelf life storage without moisture control constraints. Digi-Reel packaging is appropriate for automated assembly processes with continuous feed requirements.

SST-70X-WCS-H50-KA652 (Cut Tape Packaging, MSL 1): Suitable for applications requiring unlimited shelf life storage without moisture control constraints. Cut tape packaging is appropriate for manual assembly, kit builds, or lower-volume production runs. Functionally identical to the main part.

SST-70X-WCS-H50-KA651 (Cut Tape Packaging, MSL 3): Suitable for applications with controlled storage environments. MSL 3 rating requires storage at ≤30°C and ≤85% relative humidity, with a maximum floor life of 168 hours after bag opening. Cut tape packaging is appropriate for manual assembly or lower-volume production runs.

All three parts maintain identical electrical performance, thermal characteristics, and compliance certifications. Selection is determined by packaging format availability and moisture sensitivity requirements of the application environment.

Frequently Asked Questions (FAQ)

Q: Are SST-70X-WCS-H50-KA651 and SST-70X-WCS-H50-KA652 functionally equivalent to SST-70X-WCS-H50-JB652?

A: Yes. All three parts deliver identical electrical performance: 6500K color temperature, 5.7V forward voltage, 1.5A test current, 1120 lumens at 25°C, and 131 lm/W efficiency. Mechanical specifications, including 2020 (5050 metric) package dimensions, 120° viewing angle, and 0.6°C/W thermal resistance, are identical across all three parts.

Q: What is the difference between Digi-Reel and Cut Tape packaging?

A: Digi-Reel packaging is a continuous reel format designed for automated pick-and-place assembly equipment with high-speed feed mechanisms. Cut Tape packaging consists of individual components on tape segments, suitable for manual assembly, kit builds, or lower-volume production environments. Both formats contain the same component with identical electrical and mechanical specifications.

Q: What does MSL (Moisture Sensitivity Level) mean, and how does it affect part selection?

A: MSL indicates the maximum moisture exposure a component can tolerate before soldering. MSL 1 (Unlimited) allows indefinite storage without moisture control. MSL 3 (168 Hours) requires storage at ≤30°C and ≤85% relative humidity, with a maximum floor life of 168 hours after the moisture barrier bag is opened. Selection depends on your storage and handling environment. Both MSL 1 parts (SST-70X-WCS-H50-JB652 and SST-70X-WCS-H50-KA652) are suitable for environments without strict moisture control.

Q: Can I substitute SST-70X-WCS-H50-KA651 for SST-70X-WCS-H50-JB652 in my application?

A: Functional substitution is possible. Both parts are electrically and mechanically identical. However, SST-70X-WCS-H50-KA651 has MSL 3 rating, requiring controlled storage conditions (≤30°C, ≤85% RH, 168-hour floor life after bag opening). If your application environment does not provide these storage controls, SST-70X-WCS-H50-KA652 (MSL 1) is the preferred substitute.

Q: Are all three parts RoHS3 compliant?

A: Yes. SST-70X-WCS-H50-JB652, SST-70X-WCS-H50-KA651, and SST-70X-WCS-H50-KA652 are all ROHS3 compliant with identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Q: What is the thermal resistance specification, and why is it important?

A: Thermal resistance of 0.6°C/W indicates the temperature rise per watt of power dissipation in the package. All three parts share this specification. This parameter is critical for thermal design calculations in high-brightness applications to ensure junction temperature remains within safe operating limits.

Q: Do these parts have identical viewing angles?

A: Yes. All three parts have a 120° viewing angle, indicating the same light distribution pattern and beam characteristics.

Q: What is the CRI value, and is it the same across all three parts?

A: CRI (Color Rendering Index) of 65 indicates the color accuracy of the light output. All three parts have identical CRI values, ensuring consistent color reproduction in applications requiring specific color rendering characteristics.
