Substitute Part Grouping Explanation

Substitute parts for the ASMF-PWG2-N45H0 are identified based on the following allowable parameters:

• Color and CCT match: White, Cool 6500K
• Package compatibility: 1212 (3030 Metric) surface mount
• Mounting type: Surface mount
• Viewing angle: 120°
• CRI: 80
• Physical dimensions: 0.118" L x 0.118" W (3.00mm x 3.00mm)
• Height - Seated (Max): 0.031" (0.80mm)

The ASMF-PWG8-NPRHM meets these substitution criteria while offering active product status and improved performance characteristics within the same package footprint and optical specifications.

Parameter Comparison

Engineering Selection Recommendations

The ASMF-PWG8-NPRHM is the primary substitute for the obsolete ASMF-PWG2-N45H0. Both parts are manufactured by Broadcom Limited and share identical package geometry, color temperature, CRI, and viewing angle specifications. The substitute part carries active product status, ensuring continued availability and supply chain reliability.

Circuit design modifications are required when implementing the ASMF-PWG8-NPRHM as a replacement. The substitute operates at 3.2V forward voltage compared to the original 6.3V, and the test current is 300mA versus 150mA. These electrical differences necessitate recalculation of current-limiting resistor values and power supply voltage requirements. The substitute delivers higher luminous flux (132 lm typical) and improved efficiency (138 lm/W) at its rated test current.

Both parts comply with ROHS3 and REACH requirements and carry the same ECCN and HTSUS classifications, supporting regulatory and compliance continuity.

Frequently Asked Questions (FAQ)

Q: Can the ASMF-PWG8-NPRHM be used as a direct drop-in replacement for the ASMF-PWG2-N45H0?

A: The parts share identical package dimensions (1212/3030 Metric), mounting type, color temperature (6500K), CRI (80), and viewing angle (120°), allowing physical and optical compatibility. However, electrical parameters differ significantly. The substitute requires circuit redesign due to lower forward voltage (3.2V vs. 6.3V) and higher test current (300mA vs. 150mA). Current-limiting resistor values and power supply voltage must be recalculated.

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete vs. active), forward voltage (6.3V vs. 3.2V), test current (150mA vs. 300mA), luminous flux (105 lm vs. 132 lm), efficiency (111 lm/W vs. 138 lm/W), and thermal resistance (10°C/W vs. 18°C/W). All optical and mechanical parameters remain identical.

Q: Are there any compliance or certification differences?

A: Both parts carry ROHS3 compliance and REACH unaffected status. The ASMF-PWG8-NPRHM's RoHS status is not specified in available documentation. Both share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Q: What is the impact of the different thermal resistance values?

A: The substitute part has higher thermal resistance (18°C/W vs. 10°C/W), meaning it dissipates heat less efficiently. At equivalent power levels, the substitute will reach higher junction temperatures. Thermal management considerations may be necessary depending on application duty cycle and ambient conditions.

Q: How does the efficiency improvement affect system design?

A: The ASMF-PWG8-NPRHM delivers 138 lm/W compared to 111 lm/W for the original part. At the substitute's rated test current (300mA), this represents a 24% efficiency gain. However, direct power consumption comparison requires accounting for the different operating voltages and currents in your specific circuit design.
