Parameter Comparison

Engineering Selection Recommendations

APTR3216SURCK is the qualified substitute for APTR3216SRCPRV.

Basis for Selection:

The APTR3216SURCK provides direct mechanical and optical compatibility with identical package dimensions, mounting configuration, and viewing angle. Both components share the same 1206 (3216 Metric) form factor and bottom entry surface mount design, ensuring PCB layout compatibility without modification.

The substitute maintains electrical compatibility within standard design tolerances. The forward voltage increases from 1.85V to 1.95V (0.10V differential), which is within typical circuit design margins for LED indication applications. The test current remains constant at 20mA.

The APTR3216SURCK operates in the red spectrum with a dominant wavelength of 630nm compared to 640nm in the main part. Both wavelengths fall within the standard red LED range and maintain the same colorless, clear lens configuration with 120° viewing angle.

Regulatory compliance is maintained. Both components are ROHS3 compliant with identical Moisture Sensitivity Level (MSL) ratings of 3 (168 Hours).

Critical Advantage: The APTR3216SURCK is classified as an active product with significantly higher inventory availability (59,954 pcs) compared to the obsolete APTR3216SRCPRV (683 pcs). The substitute offers improved luminous intensity at 80mcd versus 30mcd, providing enhanced brightness for indication applications.

Frequently Asked Questions (FAQ)

Q: Can APTR3216SURCK be used as a direct replacement for APTR3216SRCPRV without PCB modifications?

A: Yes. Both components share identical package dimensions (3.20mm L x 1.60mm W x 1.05mm max height), mounting type (Surface Mount, Bottom Entry), and 1206 (3216 Metric) case specification. No PCB layout changes are required.

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

A: The APTR3216SRCPRV operates at 1.85V typical forward voltage, while the APTR3216SURCK operates at 1.95V typical forward voltage. The 0.10V difference is within standard design tolerances for LED indication circuits and does not require circuit redesign in typical applications.

Q: How do the wavelengths compare?

A: The APTR3216SRCPRV has a dominant wavelength of 640nm (peak 655nm), while the APTR3216SURCK has a dominant wavelength of 630nm (peak 645nm). Both operate in the red spectrum. The wavelength difference is visually imperceptible in standard indication applications and both maintain the same colorless, clear lens configuration.

Q: What is the brightness difference?

A: The APTR3216SURCK provides 80mcd luminous intensity compared to 30mcd for the APTR3216SRCPRV at 20mA test current. The substitute offers approximately 2.7 times greater brightness, which may require circuit current limiting adjustment if the original design was optimized for the lower intensity.

Q: Why is the substitute part recommended?

A: The APTR3216SURCK is an active product with robust supply availability (59,954 pcs in stock) versus the obsolete APTR3216SRCPRV (683 pcs). The substitute maintains full mechanical, optical, and regulatory compatibility while providing superior luminous intensity and long-term supply security.

Q: Are there any compliance differences?

A: No. Both components are ROHS3 compliant with identical Moisture Sensitivity Level (MSL) ratings of 3 (168 Hours). Regulatory and environmental compliance requirements are fully maintained with the substitute part.

Q: What packaging options are available?

A: The APTR3216SRCPRV is supplied in standard packaging (-), while the APTR3216SURCK is available in Tape & Reel (TR) format, which is standard for high-volume production and automated assembly processes.
