Key Parameters

Substitute Part Grouping Explanation

The SMTL4-BC-YG qualifies as a parametric equivalent based on the following substitution criteria:

Critical Parameters (must be identical):

• Package type: 4-PLCC
• Color configuration: Green and Yellow independent outputs
• Forward voltage: 1.9V Green, 1.9V Yellow
• Test current: 20mA Green, 20mA Yellow
• Millicandela ratings: 40mcd Green, 16mcd Yellow
• Wavelength dominants: 570nm Green, 585nm Yellow
• Lens size: 2.40mm diameter
• Mounting type: Surface Mount

Differences:

• SMTL4-BC-YG carries Active product status (vs. Obsolete)
• SMTL4-BC-YG height maximum: 2.05mm (vs. 1.95mm for SMP4-BC-YG)
• SMTL4-BC-YG includes RoHS3 compliance and REACH unaffected status
• Packaging: Tape & Reel for SMTL4-BC-YG (vs. unspecified for SMP4-BC-YG)

Parameter Comparison

Engineering Selection Recommendations

The SMTL4-BC-YG functions as a direct parametric substitute for the obsolete SMP4-BC-YG across all critical electrical and optical specifications. The substitute part carries Active product status, ensuring continued availability and manufacturing support. SMTL4-BC-YG includes RoHS3 compliance and REACH unaffected certification, addressing regulatory requirements for modern designs. The maximum height difference of 0.1mm (2.05mm versus 1.95mm) is within typical PCB assembly tolerances and does not present mechanical constraints in standard applications. Tape & Reel packaging for the SMTL4-BC-YG supports high-volume production workflows.

Frequently Asked Questions (FAQ)

Can SMTL4-BC-YG be used as a direct replacement for SMP4-BC-YG? Yes. The SMTL4-BC-YG maintains identical forward voltage, test current, intensity ratings, wavelengths, and lens geometry. The 4-PLCC package pinouts are equivalent, supporting drop-in substitution.

What are the physical mounting considerations? Both parts use 4-PLCC surface mount packaging with identical footprints (3.20mm L x 2.80mm W). The height difference of 0.1mm falls within standard PCB assembly and solder reflow specifications.

How does product status affect selection? The SMP4-BC-YG is obsolete; SMTL4-BC-YG is Active. Active status guarantees ongoing manufacturing, quality control, and procurement availability. For new designs or production restarts, the SMTL4-BC-YG is the recommended selection.

What certifications does the substitute part carry? SMTL4-BC-YG is RoHS3 compliant and REACH unaffected, supporting compliance with environmental and hazardous substance regulations.

Are the optical specifications identical? Yes. Both parts deliver 40mcd at 570nm (green) and 16mcd at 585nm (yellow) with 120° viewing angles and round flat-top lenses.
