Key Parameters

Substitute Part Grouping Explanation

Substitution of the SST-90-R-F11-HJ102 is determined by the following critical parameters:

Mechanical Compatibility:

• Package type: 0404 (1010 Metric) surface mount
• Footprint dimensions: 11.00mm x 10.00mm
• Height constraints: Maximum seated height 5.45mm

Electrical Compatibility:

• Color: Red spectrum
• Wavelength range: 615nm ~ 623nm
• Forward voltage (Vf): Nominal 2.1V
• Thermal resistance: 0.5°C/W

Regulatory & Compliance:

• RoHS3 compliance
• REACH unaffected status
• MSL rating: 1 (Unlimited)

The SBT-90-R-F75-HN100 qualifies as a substitute based on identical package geometry, matching thermal resistance, equivalent wavelength specification, and identical compliance certifications. Differences in current ratings, forward voltage, and luminous flux reflect design variations within the same product category and do not preclude substitution where application requirements permit.

Parameter Comparison

Engineering Selection Recommendations

The SBT-90-R-F75-HN100 is the designated substitute for the obsolete SST-90-R-F11-HJ102. Selection is based on the following engineering criteria:

Mechanical Fit: Both components share identical package dimensions (0404/1010 Metric) and footprint specifications, ensuring direct PCB compatibility. The SBT-90 exhibits a lower seated height (1.71mm vs. 5.45mm), which presents no clearance conflict in standard applications.

Electrical Equivalence: Wavelength specifications are within the red spectrum range (620nm vs. 619nm nominal), meeting color matching requirements. Both components maintain identical thermal resistance (0.5°C/W), ensuring equivalent thermal management characteristics in circuit design.

Regulatory Compliance: Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL rating of 1 (Unlimited), satisfying environmental and handling requirements for production environments.

Product Availability: The SBT-90-R-F75-HN100 is active in production with confirmed inventory availability, addressing the obsolescence of the original component.

Frequently Asked Questions (FAQ)

Q: Can the SBT-90-R-F75-HN100 be used as a direct replacement for the SST-90-R-F11-HJ102?

A: Yes, within the constraints of your application's electrical requirements. Both components share identical package geometry and thermal characteristics. The primary differences are forward voltage (2.7V vs. 2.1V), test current (14.6A vs. 3.15A), and luminous flux output. Circuit design must accommodate these electrical variations.

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

A: The SBT-90-R-F75-HN100 operates at higher current levels (14.6A test vs. 3.15A) and produces greater luminous flux (1350lm vs. 475lm). Forward voltage is higher (2.7V vs. 2.1V). Efficiency at test current differs (37 lm/W vs. 72 lm/W). Both maintain identical package dimensions and thermal resistance.

Q: Are there any height clearance concerns with the SBT-90-R-F75-HN100?

A: No. The SBT-90-R-F75-HN100 has a lower seated height (1.71mm) compared to the SST-90-R-F11-HJ102 (5.45mm), providing additional clearance margin in standard PCB layouts.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (Unlimited), meeting identical environmental and regulatory requirements.

Q: What should be considered when switching from SST-90 to SBT-90 series?

A: Circuit design must account for the higher forward voltage and different current characteristics of the SBT-90 series. Power supply voltage, current limiting resistors, and thermal management should be re-evaluated based on the SBT-90-R-F75-HN100 specifications to ensure proper operation and component longevity.
