APA2106SRCPRV Equivalent & Substitute Parts

Part Overview

The APA2106SRCPRV is a red LED indication component manufactured by Kingbright, configured as a 2-SMD surface mount right-angle package with no lead. This part features a 640nm dominant wavelength, 1.85V typical forward voltage, and 30mcd luminous intensity with a 120° viewing angle. The component is classified as obsolete product status, necessitating identification of active equivalent alternatives for ongoing design requirements and procurement continuity.

• Lens size: 1.70mm x 0.60mm
• Physical dimensions and height envelope

Electrical Compatibility:

• Color: Red
• Lens transparency: Clear
• Forward voltage range: Nominal 1.85V to 1.95V
• Test current: 20mA
• Wavelength range: 630nm to 660nm dominant wavelength

Regulatory & Environmental:

• RoHS3 compliance
• MSL rating: 3 (168 Hours)
• REACH unaffected status

The APA2107SURCK meets all mechanical and electrical compatibility criteria while maintaining identical regulatory compliance and environmental ratings.

Engineering Selection Recommendations

The APA2107SURCK is the designated substitute for the obsolete APA2106SRCPRV based on the following engineering criteria:

Product Status Alignment: The APA2107SURCK maintains active product status with Kingbright, ensuring ongoing availability and supply chain continuity for new designs and production requirements.

Regulatory Compliance: Both components maintain identical RoHS3 compliance, MSL rating of 3 (168 Hours), and REACH unaffected status, satisfying all environmental and regulatory requirements without modification to existing certifications or documentation.

Mechanical Compatibility: The substitute part maintains identical package configuration (2-SMD, No Lead), mounting type (Surface Mount, Right Angle), lens style (Rectangle with Domed Top), and lens dimensions (1.70mm x 0.60mm). The maximum height increases from 0.60mm to 0.70mm, requiring verification of PCB assembly clearance in height-constrained applications.

Electrical Compatibility: Forward voltage increases from 1.85V to 1.95V (0.10V differential), remaining within acceptable circuit design tolerances for standard LED indication circuits. Test current remains constant at 20mA. Wavelength shift from 640nm dominant to 630nm dominant remains within the red spectrum classification.

Performance Enhancement: The substitute provides increased luminous intensity (220mcd versus 30mcd) and expanded viewing angle (140° versus 120°), offering improved visibility characteristics for indication applications.

Frequently Asked Questions (FAQ)

Q: Can the APA2107SURCK directly replace the APA2106SRCPRV in existing PCB assemblies?

A: Direct replacement is mechanically and electrically compatible with one consideration: the APA2107SURCK has a maximum height of 0.70mm compared to 0.60mm for the APA2106SRCPRV. Verify that the additional 0.10mm height does not violate PCB assembly clearance requirements or conformal coating processes.

Q: What is the impact of the forward voltage difference between these parts?

A: The forward voltage increases from 1.85V to 1.95V, a 0.10V differential. For standard LED indication circuits operating at 5V or higher supply voltages with current-limiting resistors, this difference is absorbed within normal circuit design margins and does not require resistor recalculation.

Q: Why does the APA2107SURCK have significantly higher luminous intensity?

A: The APA2107SURCK is rated at 220mcd compared to 30mcd for the APA2106SRCPRV. This enhanced brightness is an inherent characteristic of the active substitute design. Circuit designs relying on specific brightness levels should incorporate appropriate current-limiting resistors to control LED intensity if necessary.

Q: Are there packaging differences between these components?

A: The APA2106SRCPRV is supplied in standard packaging, while the APA2107SURCK is supplied in Tape & Reel (TR) format. Both components use identical 2-SMD, No Lead package configuration. Tape & Reel packaging is standard for high-volume surface mount assembly operations.

Q: Do both parts meet the same environmental and regulatory standards?

A: Yes. Both the APA2106SRCPRV and APA2107SURCK are ROHS3 compliant, carry MSL rating 3 (168 Hours), and are REACH unaffected. No changes to compliance documentation or certifications are required when substituting between these parts.

Q: What is the wavelength difference and does it affect color perception?

A: The dominant wavelength shifts from 640nm to 630nm. Both wavelengths are within the red spectrum range. The visual color difference is negligible for standard indication applications, though the 630nm wavelength may appear slightly more orange-red compared to the 640nm reference.
