Parameter Comparison

Engineering Selection Recommendations

The ASMW-PWG4-NMQEE is the designated manufacturer-recommended substitute for the obsolete ASMW-PWG4-NLPEE. Selection of the ASMW-PWG4-NMQEE is based on the following engineering criteria:

Product Status Alignment: The ASMW-PWG4-NMQEE maintains active product status with Broadcom Limited, ensuring continued availability and manufacturing support. The ASMW-PWG4-NLPEE is classified as obsolete, making the ASMW-PWG4-NMQEE the appropriate choice for new designs and ongoing production requirements.

Electrical and Optical Equivalence: Both parts operate at identical forward voltage (6.1V typical), test current (150mA), and maximum current (350mA). Color temperature specification (5000K) and Color Rendering Index (80) are identical. Luminous flux at 25°C and 150mA test current differs marginally: the ASMW-PWG4-NMQEE delivers 136lm (125–145lm range) compared to 130lm (120–140lm range) for the ASMW-PWG4-NLPEE. This represents a 4.6% increase in nominal flux output, with overlapping tolerance ranges ensuring functional compatibility.

Mechanical and Thermal Compatibility: Package type, case designation, physical dimensions, seated height, and thermal resistance are identical between both parts. Direct mechanical substitution is supported without PCB layout modification.

Compliance and Regulatory Alignment: Both parts maintain ROHS3 compliance, identical Moisture Sensitivity Level (MSL 3, 168 Hours), and matching ECCN and HTSUS classifications. No regulatory or compliance barriers exist for substitution.

Packaging Availability: The ASMW-PWG4-NMQEE is available in Tape & Reel (TR) packaging with significantly higher inventory (100,640 Pcs) compared to the ASMW-PWG4-NLPEE (1,054 Pcs). This ensures supply chain continuity and cost-effective procurement for volume applications.

Frequently Asked Questions (FAQ)

Q: Can the ASMW-PWG4-NMQEE be used as a direct replacement for the ASMW-PWG4-NLPEE in existing designs?

A: Yes. The ASMW-PWG4-NMQEE is electrically, optically, mechanically, and thermally equivalent to the ASMW-PWG4-NLPEE. No circuit modifications, PCB layout changes, or firmware adjustments are required. Both parts operate at 6.1V forward voltage, 150mA test current, and deliver 5000K cool white light with 120° viewing angle in identical 2-PLCC 1411 (3528 Metric) packages.

Q: What is the difference in luminous flux between these two parts?

A: The ASMW-PWG4-NMQEE delivers 136lm (125–145lm tolerance range) at 25°C and 150mA, compared to 130lm (120–140lm tolerance range) for the ASMW-PWG4-NLPEE. This represents a 4.6% increase in nominal output. The tolerance ranges overlap, confirming functional compatibility. Luminous efficacy increases from 142 lm/W to 149 lm/W, indicating improved energy efficiency in the substitute part.

Q: Why is the ASMW-PWG4-NLPEE classified as obsolete?

A: The ASMW-PWG4-NLPEE is designated obsolete by Broadcom Limited, indicating discontinued manufacturing and end-of-life status. The ASMW-PWG4-NMQEE is the active equivalent part maintained in current production.

Q: Are there any packaging differences between the ASMW-PWG4-NLPEE and ASMW-PWG4-NMQEE?

A: The ASMW-PWG4-NLPEE is supplied in standard packaging (not specified as Tape & Reel). The ASMW-PWG4-NMQEE is available in Tape & Reel (TR) packaging, which is standard for high-volume surface-mount assembly operations. Both parts use identical 2-PLCC component packaging with 1411 (3528 Metric) case designation.

Q: Do both parts meet the same compliance and regulatory requirements?

A: Yes. Both the ASMW-PWG4-NLPEE and ASMW-PWG4-NMQEE are ROHS3 compliant, carry identical Moisture Sensitivity Level (MSL 3, 168 Hours), and share the same ECCN (EAR99) and HTSUS code (8541.41.0000) classifications. No compliance barriers exist for substitution.

Q: What is the thermal resistance specification for these LEDs?

A: Both parts specify 15°C/W thermal resistance of package. This parameter is identical and ensures equivalent thermal performance in circuit applications.
