Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ASMF-PWG2-N35A0 are identified based on the following critical parameters that determine functional compatibility:

Color and CCT: Warm white 2700K color temperature must be maintained for consistent lighting characteristics.

Package and Mechanical Compatibility: 1212 (3030 Metric) surface-mount package with identical footprint dimensions (3.00mm x 3.00mm) and maximum seated height (0.80mm) ensures PCB layout compatibility without redesign.

Viewing Angle: 120° viewing angle specification must be preserved for optical performance consistency.

Electrical Operating Range: Forward voltage, test current, and maximum current ratings define the power supply and circuit design constraints. Substitutes must operate within compatible voltage and current ranges to function in existing driver circuits.

Luminous Flux and Efficiency: Lumens output and lm/W efficiency determine lighting performance. Substitutes must deliver comparable or superior luminous output at their respective operating currents.

Color Rendering Index: CRI of 80 establishes the color quality baseline for warm white applications.

Compliance and Status: Active product status with current manufacturing availability and maintained RoHS3 compliance ensure long-term supply chain viability.

Parameter Comparison

Engineering Selection Recommendations

The ASMF-PWG8-NMPAM is the manufacturer-recommended substitute for the obsolete ASMF-PWG2-N35A0. Both components are manufactured by Broadcom Limited and share identical package geometry, color temperature, CRI, and viewing angle specifications, ensuring direct mechanical and optical compatibility.

The substitute part is classified as Active product status, providing assured long-term availability and supply chain continuity compared to the Obsolete status of the main part. The ASMF-PWG2-N35A0 is ROHS3 Compliant; compliance status for the substitute should be confirmed with the manufacturer or distributor prior to final design implementation.

Electrical differences exist between the two parts: the substitute operates at 3.2V forward voltage versus 6.3V for the main part, and specifies 300mA test current versus 150mA. These differences require circuit redesign to accommodate the lower voltage and higher current requirements. The substitute delivers superior luminous efficiency at 120 lm/W compared to 106 lm/W for the main part, and provides higher luminous flux output (115lm typical versus 100lm typical) at its specified operating current.

Frequently Asked Questions (FAQ)

Q: Can the ASMF-PWG8-NMPAM be used as a direct drop-in replacement without circuit modification?

A: No. While the mechanical package and optical characteristics are identical, the electrical specifications differ significantly. The substitute requires a different power supply voltage (3.2V versus 6.3V) and operates at double the test current (300mA versus 150mA). Circuit redesign is necessary to accommodate these electrical differences.

Q: Are the package dimensions and PCB footprints identical between the main part and substitute?

A: Yes. Both components use the 1212 (3030 Metric) surface-mount package with identical dimensions of 3.00mm x 3.00mm and maximum seated height of 0.80mm. PCB layout and footprint designs require no modification.

Q: Does the substitute part maintain the same color temperature and color rendering characteristics?

A: Yes. Both parts specify warm white 2700K color temperature and CRI of 80, ensuring identical color quality and appearance in lighting applications.

Q: What is the primary reason for substitution?

A: The ASMF-PWG2-N35A0 is classified as Obsolete, creating supply chain risk. The ASMF-PWG8-NMPAM is an Active product with current manufacturing availability, ensuring long-term component sourcing for production and field replacement requirements.

Q: How do the luminous output specifications compare?

A: The substitute delivers 115lm typical flux at 300mA test current, compared to 100lm typical for the main part at 150mA test current. The substitute also provides superior efficiency at 120 lm/W versus 106 lm/W. Actual luminous output in an application depends on the circuit design and operating current selected.
