Substitute Part Grouping Explanation

Substitute parts for the SMP2-GC are identified based on strict equivalence of the following electrical, optical, and mechanical parameters:

Critical Substitution Parameters:

• Color: Green
• Wavelength - Dominant: 570nm
• Voltage - Forward (Vf) (Typ): 1.9V
• Current - Test: 20mA
• Millicandela Rating: 40mcd
• Viewing Angle: 120°
• Package / Case: 2-PLCC
• Size / Dimension: 3.20mm L x 2.80mm W
• Mounting Type: Surface Mount
• Lens Style: Round with Flat Top
• Lens Transparency: Clear
• Moisture Sensitivity Level (MSL): 4 (72 Hours)

The SMTL2-GC meets all critical electrical and optical parameters required for direct substitution. Both parts share identical wavelength, forward voltage, test current, luminous intensity, viewing angle, and mechanical dimensions. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The SMTL2-GC is the direct parametric equivalent for the SMP2-GC. Key factors supporting this substitution:

Product Status: The SMTL2-GC maintains Active product status, ensuring ongoing availability and manufacturing support, whereas the SMP2-GC is Obsolete.

Electrical Compatibility: Both parts operate at identical forward voltage (1.9V) and test current (20mA), supporting drop-in replacement in existing circuit designs without modification.

Optical Characteristics: Wavelength, color, luminous intensity, and viewing angle are identical between both parts, ensuring equivalent performance in indication applications.

Mechanical Compatibility: Both parts share identical 2-PLCC package, footprint dimensions (3.20mm L x 2.80mm W), and surface mount mounting type. The SMTL2-GC height specification of 2.10mm is marginally higher than the SMP2-GC at 2.00mm but remains within standard component tolerances for board assembly and clearance.

Compliance: The SMTL2-GC carries ROHS3 compliance certification, supporting regulatory requirements in modern manufacturing environments.

Packaging Consideration: The SMTL2-GC is supplied in Tape & Reel format, standard for high-volume surface mount assembly operations.

Frequently Asked Questions (FAQ)

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

A: Yes. The SMTL2-GC matches all critical electrical and optical parameters of the SMP2-GC, including forward voltage, test current, wavelength, luminous intensity, viewing angle, and package dimensions. The parts are parametrically equivalent and support direct substitution.

Q: Does the 0.10mm height difference between SMP2-GC (2.00mm) and SMTL2-GC (2.10mm) affect compatibility?

A: The height difference is within standard component tolerances and does not affect PCB assembly or mechanical clearance in standard applications. Board layout and clearance margins should remain adequate for both variants.

Q: What is the significance of the SMTL2-GC being supplied in Tape & Reel format?

A: Tape & Reel packaging is the standard format for high-volume surface mount assembly. It supports automated pick-and-place equipment used in modern manufacturing. If bulk quantities are required, Tape & Reel format is the preferred supply option.

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

A: The SMTL2-GC carries explicit ROHS3 compliance certification. The SMP2-GC RoHS status is not specified in available data. For applications requiring RoHS compliance, the SMTL2-GC provides documented compliance support.

Q: Why is the SMP2-GC marked as Obsolete?

A: Component obsolescence occurs as manufacturers transition product lines and consolidate offerings. The SMTL2-GC represents the active equivalent, ensuring continued design support and manufacturing availability. Selection of the active part mitigates obsolescence-related supply and support risks.
