Engineering Selection Recommendations

The APTD3216QBC/D is a direct substitute for the obsolete UB1105W-TR based on the following engineering factors:

Product Status Alignment: The UB1105W-TR is classified as obsolete. The APTD3216QBC/D maintains active product status with current manufacturing availability, ensuring long-term supply chain continuity.

Compliance and Certification: Both components share identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS code (8541.41.0000), ensuring regulatory equivalence for procurement and export documentation.

Electrical Compatibility: Forward voltage (Vf) is identical at 3.3V, ensuring direct circuit compatibility without modification. The APTD3216QBC/D operates at 20mA test current versus 10mA for the UB1105W-TR, indicating enhanced performance capability within the same voltage envelope.

Mechanical Compatibility: Package format, mounting type, lens geometry, and footprint dimensions are identical. Maximum height differential (1.90mm versus 1.85mm) is within standard PCB assembly tolerances and does not affect mechanical clearance or thermal performance.

Moisture Sensitivity: The APTD3216QBC/D provides improved moisture sensitivity rating (MSL 3, 168 Hours) compared to the UB1105W-TR (MSL 4, 72 Hours), reducing handling and storage risk during manufacturing operations.

Optical Performance: The APTD3216QBC/D delivers 700mcd luminous intensity at 20mA test current, compared to 220mcd at 10mA for the UB1105W-TR. This represents enhanced optical output capability while maintaining identical spectral characteristics in the blue wavelength range (465nm dominant, 460nm peak).

Frequently Asked Questions (FAQ)

Q: Can the APTD3216QBC/D be used as a direct replacement for the UB1105W-TR without circuit modification?

A: Yes. Both components operate at identical forward voltage (3.3V) and share identical package format (1206/3216 Metric), mounting type (surface mount), and footprint dimensions (3.20mm L x 1.60mm W). No circuit modification is required for electrical or mechanical compatibility.

Q: What is the difference in luminous intensity between these two parts?

A: The UB1105W-TR delivers 220mcd at 10mA test current. The APTD3216QBC/D delivers 700mcd at 20mA test current. The APTD3216QBC/D provides higher optical output, which may require circuit current limiting adjustment if the original design was optimized for lower brightness levels.

Q: Are the wavelength specifications compatible?

A: Yes. The UB1105W-TR has dominant wavelength of 470nm (peak 465nm). The APTD3216QBC/D has dominant wavelength of 465nm (peak 460nm). Both components operate in the blue spectral range with negligible perceptual difference in color appearance for indication applications.

Q: What is the significance of the MSL rating difference?

A: The UB1105W-TR carries MSL 4 (72 Hours), while the APTD3216QBC/D carries MSL 3 (168 Hours). MSL 3 provides extended moisture absorption tolerance, reducing risk of component damage during storage and manufacturing processes. This represents an improvement in component robustness.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both components share identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS code (8541.41.0000). Regulatory documentation and export requirements remain unchanged.

Q: What is the packaging format for the APTD3216QBC/D?

A: The APTD3216QBC/D is supplied in Tape & Reel (TR) format with 2-SMD supplier device package configuration, providing standard surface mount assembly compatibility.

Q: Can the higher test current of the APTD3216QBC/D affect circuit performance?

A: The test current specification (20mA for APTD3216QBC/D versus 10mA for UB1105W-TR) indicates the measurement condition for luminous intensity rating. Actual circuit operation depends on the current limiting resistor design. If the original circuit was designed for 10mA operation, the APTD3216QBC/D will operate at the same current level, delivering proportionally lower brightness than its rated 700mcd specification.
