Substitute Part Grouping Explanation

Substitution of the LG L29K-F2J1-24-Z is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Package / Case: 0603 (1608 Metric)
• Color: Green
• Wavelength - Dominant: 570nm
• Voltage - Forward (Vf) (Typ): 1.7V
• Current - Test: 2mA
• Mounting Type: Surface Mount
• Lens Transparency: Diffused
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 2 (1 Year)

Allowable Variation Parameters:

• Millicandela Rating: Substitute parts may exceed the original 3.5mcd specification while maintaining all other electrical and mechanical characteristics
• Viewing Angle: Substitute parts maintain 160° specification

The substitute LG L29K-G2J1-24-Z meets all mandatory matching parameters and represents a direct functional equivalent with enhanced luminous intensity (3.92mcd versus 3.5mcd).

Parameter Comparison

Engineering Selection Recommendations

The LG L29K-G2J1-24-Z serves as a direct substitute for the LG L29K-F2J1-24-Z based on electrical and mechanical parameter equivalence. Both components share identical forward voltage, test current, package dimensions, and compliance certifications (ROHS3, REACH Unaffected). The substitute part exhibits increased luminous intensity (3.92mcd versus 3.5mcd), which represents an enhancement in optical performance while maintaining all other specifications.

Both parts carry "Not For New Designs" status from ams-OSRAM USA INC., indicating that neither component is recommended for new design implementations. For applications currently utilizing the LG L29K-F2J1-24-Z, the LG L29K-G2J1-24-Z provides functional continuity with improved brightness characteristics. The enhanced millicandela rating does not introduce incompatibility with existing circuit designs, as the forward voltage and test current remain constant.

Selection between these parts should be based on inventory availability and application-specific brightness requirements. The substitute part's higher luminous intensity may provide improved visibility in applications where indicator brightness is a design consideration.

Frequently Asked Questions (FAQ)

Q: Can the LG L29K-G2J1-24-Z replace the LG L29K-F2J1-24-Z in existing designs?

A: Yes. Both components share identical electrical characteristics (1.7V forward voltage, 2mA test current), mechanical dimensions (0603 package, 1.70mm x 0.80mm x 0.65mm), and compliance certifications. The substitute part's increased luminous intensity (3.92mcd versus 3.5mcd) does not affect circuit compatibility.

Q: What is the significance of the "Not For New Designs" status?

A: This status indicates that ams-OSRAM USA INC. has discontinued active development and support for both the LG L29K-F2J1-24-Z and LG L29K-G2J1-24-Z. For new design implementations, alternative green LED indicators from current product lines should be evaluated.

Q: Are the physical dimensions identical between the main part and substitute?

A: Yes. Both components are packaged in 0603 (1608 Metric) format with identical dimensions: 1.70mm length, 0.80mm width, and 0.65mm maximum height. PCB footprints and assembly processes remain unchanged.

Q: What is the difference between the two part numbers?

A: The primary difference is the millicandela rating. The LG L29K-G2J1-24-Z produces 3.92mcd compared to 3.5mcd for the LG L29K-F2J1-24-Z. All other electrical, mechanical, and compliance parameters are identical.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the LG L29K-F2J1-24-Z and LG L29K-G2J1-24-Z are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the Moisture Sensitivity Level (MSL) for these components?

A: Both parts carry MSL 2 (1 Year) rating, indicating standard moisture sensitivity with a one-year floor life under controlled storage conditions.

Q: Can these parts be used interchangeably in production?

A: Yes. The electrical and mechanical equivalence of both components allows interchangeable use in production environments. The substitute part's enhanced brightness may be beneficial in applications where indicator visibility is critical.
