Key Parameters

Substitute Part Grouping Explanation

Substitution of the LA T676-R1S2-1 is determined by strict adherence to the following critical parameters:

Electrical Compatibility:

• Forward voltage (Vf): 2V
• Test current: 20mA
• Wavelength - Dominant: 615nm
• Wavelength - Peak: 622nm
• Color: Amber

Mechanical Compatibility:

• Package / Case: 2-PLCC
• Lens Size: 2.40mm Dia
• Lens Style: Round with Flat Top
• Lens Color: Colorless
• Lens Transparency: Clear
• Viewing Angle: 120°
• Physical dimensions: 3.20mm L × 2.80mm W
• Height (Max): 2.10mm
• Mounting Type: Surface Mount

Regulatory & Compliance:

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected
• Moisture Sensitivity Level (MSL): 2 (1 Year)

Substitute parts must maintain identical electrical characteristics, mechanical form factor, and regulatory compliance. Variations in millicandela rating are permissible when all other parameters remain constant, as luminous intensity does not affect circuit-level compatibility or physical fit.

Engineering Selection Recommendations

LA T676-Q2T1-24-Z

This substitute part is functionally equivalent to the LA T676-R1S2-1 with active product status. All electrical parameters, mechanical dimensions, and regulatory certifications are identical. The millicandela rating is 222.5mcd compared to 196mcd in the main part, representing a 13.5% increase in luminous intensity. This part is supplied in Tape & Reel (TR) packaging format and maintains ROHS3 compliance and REACH unaffected status. Selection of this part is appropriate for applications where the increased luminous intensity is acceptable or beneficial.

LA T676-R1S2-24-Z

This substitute part maintains identical electrical and mechanical specifications to the LA T676-R1S2-1, including the same 196mcd millicandela rating. The primary distinction is active product status, ensuring continued availability and supply chain support. This part carries ROHS3 compliance and REACH unaffected status. Selection of this part is appropriate for applications requiring exact luminous intensity matching with the original component.

Both substitute parts are manufactured by ams-OSRAM USA INC. within the TOPLED® series and satisfy all regulatory requirements applicable to the main part.

Frequently Asked Questions (FAQ)

Q: Can LA T676-Q2T1-24-Z be used as a direct replacement for LA T676-R1S2-1?

A: Yes. The LA T676-Q2T1-24-Z is electrically and mechanically compatible with the LA T676-R1S2-1. Both components operate at 2V forward voltage, 20mA test current, and share identical 2-PLCC package dimensions, lens specifications, and viewing angle. The substitute part delivers 222.5mcd compared to 196mcd in the original part. This increased luminous intensity does not affect circuit compatibility or physical fit.

Q: What is the difference between LA T676-R1S2-24-Z and LA T676-Q2T1-24-Z?

A: Both parts are equivalent to the LA T676-R1S2-1 in electrical and mechanical specifications. The LA T676-R1S2-24-Z maintains the original 196mcd millicandela rating, while the LA T676-Q2T1-24-Z delivers 222.5mcd. The LA T676-Q2T1-24-Z is supplied in Tape & Reel (TR) packaging, whereas the LA T676-R1S2-24-Z packaging format is not specified in the provided data.

Q: Are these substitute parts RoHS compliant?

A: Yes. Both LA T676-Q2T1-24-Z and LA T676-R1S2-24-Z are ROHS3 compliant and REACH unaffected, matching the regulatory status of the original LA T676-R1S2-1 component.

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

A: All three parts—LA T676-R1S2-1, LA T676-Q2T1-24-Z, and LA T676-R1S2-24-Z—carry Moisture Sensitivity Level (MSL) 2 with a 1-year shelf life rating.

Q: Can I use these parts interchangeably in my PCB assembly?

A: Yes. All three parts share identical 2-PLCC package dimensions (3.20mm L × 2.80mm W, 2.10mm maximum height) and surface mount mounting type. They are mechanically and electrically interchangeable at the PCB level. Luminous intensity differences do not affect assembly compatibility.

Q: Why is the LA T676-R1S2-1 marked as obsolete?

A: The LA T676-R1S2-1 carries obsolete product status. The substitute parts LA T676-Q2T1-24-Z and LA T676-R1S2-24-Z maintain active status, ensuring continued manufacturing and supply availability for new designs and ongoing production support.
