Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASMF-PWG2-N45F0 is based on the following critical parameters:

• Color Temperature & CRI: Both parts must maintain cool white 5700K with CRI of 80 to preserve color rendering characteristics
• Package Type: Both parts use 1212 (3030 metric) surface-mount package, ensuring mechanical and thermal compatibility
• Viewing Angle: 120° viewing angle is maintained across both parts
• Electrical Compatibility: Forward voltage, test current, and maximum current ratings must be evaluated within the context of circuit design requirements
• Compliance Status: Substitute parts must maintain ROHS3 and REACH compliance for regulatory continuity
• Product Status: Active product status of the substitute ensures ongoing availability and supply chain stability

The ASMF-PWG8-NPRFM is identified as a manufacturer-recommended substitute based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

The ASMF-PWG8-NPRFM is the manufacturer-recommended substitute for the obsolete ASMF-PWG2-N45F0. Both components share identical color temperature (5700K), CRI (80), viewing angle (120°), and package form factor (1212/3030 metric), ensuring mechanical and optical compatibility.

Key differences in electrical characteristics must be evaluated within circuit design context:

• The substitute operates at lower forward voltage (3.2V vs. 6.3V) and higher test current (300mA vs. 150mA)
• The substitute delivers higher luminous flux (132lm vs. 105lm) and improved efficiency (138 lm/W vs. 111 lm/W)
• Thermal resistance is higher in the substitute (18°C/W vs. 10°C/W), requiring thermal management assessment in high-power applications

The active product status of the ASMF-PWG8-NPRFM ensures supply chain continuity and long-term availability, addressing the obsolescence of the original part.

Frequently Asked Questions (FAQ)

Q: Can the ASMF-PWG8-NPRFM be used as a direct drop-in replacement for the ASMF-PWG2-N45F0?

A: Mechanical and optical compatibility is confirmed due to identical package type (1212/3030 metric), color temperature (5700K), CRI (80), and viewing angle (120°). Electrical circuit design must be re-evaluated due to differences in forward voltage and current ratings.

Q: What are the main electrical differences between these parts?

A: The substitute operates at 3.2V forward voltage compared to 6.3V in the original part, and requires 300mA test current versus 150mA. Maximum current ratings are 350mA and 180mA respectively. Circuit design must accommodate these electrical characteristics.

Q: Are both parts compliant with current environmental regulations?

A: The ASMF-PWG2-N45F0 is confirmed ROHS3 compliant and REACH unaffected. Compliance status for the ASMF-PWG8-NPRFM is not specified in the provided data and should be confirmed with the manufacturer.

Q: How do the thermal characteristics compare?

A: The original part has thermal resistance of 10°C/W, while the substitute has 18°C/W. In thermal-constrained applications, the higher thermal resistance of the substitute may require additional thermal management considerations.

Q: What is the luminous output difference?

A: The substitute delivers 132lm at 25°C compared to 105lm in the original part, representing approximately 26% higher luminous flux output at the specified test current.
