The SMTL2-SRC meets all primary electrical parameters and mechanical specifications, with packaging available in Tape & Reel format and active product status.

Parameter Comparison

Engineering Selection Recommendations

The SMTL2-SRC is a direct electrical and mechanical equivalent to the SMP2-SRC. Both components share identical electrical specifications (1.9V forward voltage, 20mA test current, 180mcd brightness, 631nm wavelength, 120° viewing angle) and mechanical form factor (2-PLCC package, 3.20mm x 2.80mm dimensions).

The SMTL2-SRC offers the following advantages for component selection:

Product Status: The SMTL2-SRC maintains active product status, ensuring continued availability and manufacturing support, whereas the SMP2-SRC is obsolete.

Compliance: The SMTL2-SRC is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Packaging: The SMTL2-SRC is available in Tape & Reel format, supporting automated assembly processes and reducing handling costs compared to bulk packaging.

Height Tolerance: The SMTL2-SRC maximum height of 2.10mm is within acceptable tolerance for 2-PLCC applications, with a 0.10mm difference from the SMP2-SRC specification.

Frequently Asked Questions (FAQ)

Q: Can the SMTL2-SRC directly replace the SMP2-SRC in existing designs?

A: Yes. The SMTL2-SRC meets all electrical parameters (1.9V forward voltage, 20mA test current, 180mcd brightness, 631nm wavelength, 120° viewing angle) and mechanical specifications (2-PLCC package, 3.20mm x 2.80mm footprint) of the SMP2-SRC. The 0.10mm height difference (2.10mm vs 2.00mm) is within standard PCB assembly tolerances for surface mount components.

Q: What is the difference between SMP2-SRC and SMTL2-SRC packaging?

A: The SMP2-SRC is supplied in bulk packaging, while the SMTL2-SRC is supplied in Tape & Reel (TR) format. Both contain identical components. Tape & Reel packaging is optimized for automated pick-and-place assembly equipment.

Q: Are there compliance differences between these parts?

A: The SMTL2-SRC is certified ROHS3 compliant and REACH unaffected. The SMP2-SRC compliance status is not specified. Both share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Q: Why is the SMP2-SRC listed as obsolete?

A: The SMP2-SRC is classified as obsolete by the manufacturer. The SMTL2-SRC maintains active product status and is the recommended alternative for new designs and ongoing production.

Q: Are the optical characteristics identical?

A: Yes. Both components feature identical optical specifications: 631nm dominant wavelength (red), 180mcd brightness rating, 120° viewing angle, round lens with flat top, and clear lens transparency.

Q: What is the moisture sensitivity level for these components?

A: Both the SMP2-SRC and SMTL2-SRC have a Moisture Sensitivity Level (MSL) rating of 4, requiring storage at or below 30% relative humidity for 72 hours prior to soldering.
