Key Parameters

Substitute Part Grouping Explanation

Substitution of the LW M673-L2M2-LL0-1-2-R18-Z-SV is determined by alignment of the following critical parameters:

Mandatory Matching Criteria:

• Color: White
• Lens Transparency: Diffused
• Lens Color: Yellow
• Mounting Type: Surface Mount
• Viewing Angle: 120°
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 2 (1 Year)
• REACH Status: REACH Unaffected
• Manufacturer: ams-OSRAM USA INC.

Allowable Variation Parameters:

• Voltage - Forward (Vf): Tolerance within circuit design specifications
• Current - Test: Variation based on application requirements
• Millicandela Rating: Brightness variation acceptable within application luminous intensity requirements
• Package / Case: Alternative lead configurations (J-Lead to Flat Lead) permissible when PCB layout accommodates
• Lens Size: Minor dimensional variations acceptable within mechanical assembly constraints
• Overall Size / Dimension: Variation acceptable when footprint compatibility is maintained
• Height (Max): Variation acceptable within PCB clearance specifications

The substitute part KW DELPS2.RA-TIVH-FK0PM0-Z555-10-S meets all mandatory matching criteria while introducing variations in forward voltage (2.95V vs. 2.75V), test current (10mA vs. 2mA), millicandela rating (680mcd vs. 21mcd), package configuration (Flat Lead vs. J-Lead), and physical dimensions. These variations are within allowable parameters for applications where the circuit design accommodates the higher voltage and current specifications and where the increased brightness and smaller footprint are compatible with the end application.

Parameter Comparison

Engineering Selection Recommendations

Both the LW M673-L2M2-LL0-1-2-R18-Z-SV and KW DELPS2.RA-TIVH-FK0PM0-Z555-10-S are active products manufactured by ams-OSRAM USA INC. and maintain full compliance with ROHS3 and REACH regulatory requirements. Both components carry identical Moisture Sensitivity Level ratings and are suitable for equivalent environmental conditions.

Selection between these parts is determined by circuit design parameters and mechanical constraints:

Select LW M673-L2M2-LL0-1-2-R18-Z-SV when:

• Circuit design specifies 2.75V forward voltage operation
• Application requires 2mA test current specification
• 21 millicandela brightness output meets luminous intensity requirements
• J-Lead package configuration is required for PCB layout
• Larger footprint (2.00mm L x 1.40mm W) is accommodated in design
• Standard bulk packaging is acceptable for manufacturing processes

Select KW DELPS2.RA-TIVH-FK0PM0-Z555-10-S when:

• Circuit design accommodates 2.95V forward voltage operation
• Application requires 10mA test current specification
• 680 millicandela brightness output is required for increased luminous intensity
• Flat Lead package configuration is compatible with PCB assembly
• Compact footprint (1.40mm L x 0.80mm W) and reduced height (0.70mm) are advantageous
• Tape & Reel packaging format is required for automated assembly processes

Frequently Asked Questions (FAQ)

Q: Can the KW DELPS2.RA-TIVH-FK0PM0-Z555-10-S directly replace the LW M673-L2M2-LL0-1-2-R18-Z-SV in existing designs?

A: Direct replacement requires circuit design verification. The substitute part operates at 2.95V forward voltage compared to 2.75V, and draws 10mA test current compared to 2mA. The circuit must accommodate these electrical parameter differences. Additionally, the package configuration differs (Flat Lead vs. J-Lead), requiring PCB layout compatibility assessment. The substitute part delivers significantly higher brightness (680mcd vs. 21mcd), which may or may not be acceptable depending on application requirements.

Q: What are the key differences in package configuration between these parts?

A: The LW M673-L2M2-LL0-1-2-R18-Z-SV uses a 2-SMD J-Lead package with dimensions of 2.00mm L x 1.40mm W and maximum height of 1.40mm. The KW DELPS2.RA-TIVH-FK0PM0-Z555-10-S uses a 2-SMD Flat Lead package with dimensions of 1.40mm L x 0.80mm W and maximum height of 0.70mm. The J-Lead configuration features leads that extend from the package body, while the Flat Lead configuration has leads that lie flat. PCB footprints and assembly processes differ between these configurations.

Q: Are both parts suitable for the same environmental and regulatory applications?

A: Both parts are ROHS3 Compliant and REACH Unaffected, making them suitable for equivalent regulatory environments. Both carry Moisture Sensitivity Level 2 (1 Year) ratings, indicating identical moisture handling and storage requirements. Both are active products from the same manufacturer, ensuring ongoing availability and support.

Q: What is the brightness difference between these two parts?

A: The LW M673-L2M2-LL0-1-2-R18-Z-SV delivers 21 millicandela, while the KW DELPS2.RA-TIVH-FK0PM0-Z555-10-S delivers 680 millicandela. This represents a 32-fold increase in luminous intensity. The substitute part is significantly brighter and is suitable only for applications where this increased brightness is either required or acceptable within the design specifications.

Q: How do the forward voltage specifications affect circuit design?

A: The LW M673-L2M2-LL0-1-2-R18-Z-SV operates at 2.75V typical forward voltage, while the KW DELPS2.RA-TIVH-FK0PM0-Z555-10-S operates at 2.95V. This 0.20V difference affects current-limiting resistor calculations and power supply voltage requirements. Circuits designed for the lower voltage part may require resistor value adjustments when using the higher voltage substitute to maintain proper current levels and brightness output.

Q: What packaging format differences exist between these parts?

A: The LW M673-L2M2-LL0-1-2-R18-Z-SV is supplied in bulk packaging, suitable for manual assembly or small-scale production. The KW DELPS2.RA-TIVH-FK0PM0-Z555-10-S is supplied in Tape & Reel (TR) format, optimized for automated pick-and-place assembly processes. Selection depends on manufacturing process requirements and production volume.
