Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ASMF-PWG2-N45D0 must satisfy the following criteria based on provided electrical and mechanical parameters:

Color and CCT Match: Substitute parts must be white LEDs with 4000K neutral color temperature to maintain consistent lighting characteristics in the application.

Package Compatibility: All substitute parts must use the 1212 (3030 metric) surface-mount package to ensure PCB footprint compatibility without redesign.

Viewing Angle: Substitute parts must maintain the 120° viewing angle specification to preserve optical distribution properties.

CRI Specification: Substitute parts must maintain 80 CRI or higher to ensure color rendering consistency.

Manufacturer Continuity: Broadcom Limited is the specified manufacturer for this product line, ensuring consistent quality and supply chain reliability.

The ASMF-PWG8-NPRDM meets these substitution criteria while offering improved electrical efficiency and active product status.

Parameter Comparison

Engineering Selection Recommendations

The ASMF-PWG8-NPRDM is the manufacturer-recommended substitute for the obsolete ASMF-PWG2-N45D0. Both components are manufactured by Broadcom Limited and maintain identical color temperature (4000K), CRI (80), viewing angle (120°), and physical package dimensions (1212/3030 metric).

The ASMF-PWG8-NPRDM carries active product status, ensuring ongoing availability and supply chain support. This part is ROHS3 compliant and maintains equivalent environmental compliance standards.

Key electrical differences exist between the two parts: the ASMF-PWG8-NPRDM operates at lower forward voltage (3.2V versus 6.3V) while delivering higher luminous flux (128 lm versus 105 lm) at double the test current (300mA versus 150mA). The substitute part achieves superior luminous efficiency (133 lm/W versus 111 lm/W).

Circuit design modifications are required to accommodate the different voltage and current specifications. The thermal resistance of the substitute part (18°C/W) is higher than the original (10°C/W), requiring thermal management evaluation in high-power applications.

Frequently Asked Questions (FAQ)

Q: Can the ASMF-PWG8-NPRDM be used as a direct drop-in replacement for the ASMF-PWG2-N45D0?

A: Physical package compatibility is confirmed (both use 1212/3030 metric surface-mount packages with identical dimensions). However, electrical circuit modifications are required due to different forward voltage (3.2V versus 6.3V) and test current (300mA versus 150mA) specifications. PCB footprints are compatible without redesign, but power supply and current-limiting circuits must be recalculated.

Q: Are the color characteristics identical between these parts?

A: Yes. Both parts are specified as white LEDs with 4000K neutral color temperature and 80 CRI. Color rendering and appearance will be consistent in the application.

Q: What is the impact of the higher thermal resistance in the substitute part?

A: The ASMF-PWG8-NPRDM has thermal resistance of 18°C/W compared to 10°C/W in the original part. In applications with sustained high current operation, thermal management design should be reviewed to ensure junction temperature remains within acceptable limits.

Q: Is the substitute part available in production quantities?

A: Yes. The ASMF-PWG8-NPRDM is listed as active product status with 1091 pieces in stock, ensuring availability for production and maintenance applications.

Q: Are compliance certifications equivalent?

A: Both parts are ROHS3 compliant and carry equivalent environmental compliance status. The substitute part maintains the same regulatory classification (ECCN: EAR99, HTSUS: 8541.41.0000).
