LED BLUE CLEAR 1206 SMD 11-21/BHC-AP2R1/2T Equivalent & Substitute Parts

Part Overview

The Everlight Electronics 11-21/BHC-AP2R1/2T is a blue LED indication component in 1206 (3016 Metric) surface mount package. This discrete LED operates at 3.5V forward voltage with a dominant wavelength of 471nm and produces 99mcd at 20mA test current. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing design support, maintenance, and production continuity. The clear colorless lens with round flat-top design provides a 60° viewing angle suitable for standard indication applications.

Engineering Selection Recommendations

The 12-21C/BHC-ANQ/2C is a direct functional substitute for the obsolete 11-21/BHC-AP2R1/2T based on the following engineering criteria:

Product Status Alignment: The substitute part is Active status, ensuring ongoing availability and supply chain continuity. The main part is Obsolete, making substitution necessary for new production and long-term support.

Electrical Compatibility: Both parts operate at 20mA test current with matching dominant and peak wavelengths (471nm and 468nm respectively). The forward voltage difference (3.5V vs 3.3V) is within standard circuit design tolerance for indication applications. The millicandela rating reduction from 99mcd to 70mcd remains suitable for indication function.

Mechanical and Optical Compatibility: Both components use identical 1206 (3016 Metric) surface mount packages with matching footprint dimensions (3.00mm L x 1.50mm W). The substitute part has reduced maximum height (1.00mm vs 1.50mm), providing improved PCB clearance. Lens style differs (Round Flat Top vs Rectangle Domed Top), but both provide clear colorless optical transmission for blue indication.

Compliance and Certifications: The substitute part carries ROHS3 compliance certification. Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. Moisture sensitivity differs (MSL 3 vs MSL 2), requiring appropriate handling protocols during assembly.

Selection Basis: Selection of the 12-21C/BHC-ANQ/2C is based on matching color, wavelength specifications, package type, mounting method, and optical transparency. The part is suitable for direct replacement in standard blue LED indication circuits.

Frequently Asked Questions (FAQ)

Q: Can the 12-21C/BHC-ANQ/2C directly replace the 11-21/BHC-AP2R1/2T on existing PCBs?

A: Yes. Both parts use identical 1206 (3016 Metric) surface mount packages with matching footprint dimensions (3.00mm L x 1.50mm W). The substitute part has lower maximum height (1.00mm vs 1.50mm), which improves PCB clearance compatibility.

Q: What is the impact of the forward voltage difference (3.5V vs 3.3V)?

A: The 0.2V difference is within standard design tolerance for indication LED circuits. Existing current-limiting resistor values will function correctly with the substitute part. No circuit redesign is required.

Q: Does the reduced millicandela rating (70mcd vs 99mcd) affect circuit function?

A: The 70mcd rating of the substitute part remains suitable for standard indication applications. Visual brightness reduction is approximately 29%, which is acceptable for indication function. Application-specific brightness requirements should be evaluated.

Q: Why does the substitute part have a different lens style?

A: The substitute part uses a Rectangle with Domed Top lens instead of Round with Flat Top. Both lens styles provide clear colorless optical transmission for blue indication. The different geometry does not affect electrical function or wavelength characteristics.

Q: What is the significance of the different Moisture Sensitivity Levels (MSL)?

A: The main part has MSL 2 (1 Year shelf life), while the substitute has MSL 3 (168 Hours shelf life). This requires stricter moisture control during storage and assembly. Standard MSL 3 handling procedures must be followed during component storage and PCB assembly processes.

Q: Are there any compliance differences between the two parts?

A: The substitute part carries ROHS3 compliance certification. Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. No compliance barriers exist for substitution.

Q: What is the viewing angle difference between the parts?

A: The main part has a 60° viewing angle, while the substitute has a 100° viewing angle. The wider viewing angle of the substitute part provides improved visibility from off-axis positions, which is beneficial for indication applications.

Q: Is the substitute part available in the same packaging format?

A: The main part uses standard packaging (not specified), while the substitute is available in Tape & Reel (TR) format. Tape & Reel packaging is standard for high-volume surface mount assembly and provides improved handling efficiency.
