Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASMF-PWG2-N35B0 is determined by the following criteria:

Primary Compatibility Parameters:

• Color and CCT: White, Warm 3000K (exact match required)
• Package / Case: 1212 (3030 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Viewing Angle: 120° (exact match required)
• CRI: 80 (exact match required)

Secondary Electrical Parameters:

• Forward Voltage (Vf): Allowable range determined by circuit design; substitutes may operate at different voltage levels if the application circuit can accommodate the change
• Test Current: Substitutes may operate at different current levels; circuit design must support the alternative current specification
• Flux Output: Substitutes must maintain functional luminous output within application requirements

The ASMF-PWG8-NMPBM qualifies as a substitute based on matching color, CCT, package, mounting type, and viewing angle specifications. However, electrical characteristics differ significantly, requiring circuit-level evaluation.

Parameter Comparison

Engineering Selection Recommendations

The ASMF-PWG8-NMPBM is available as an active product from Broadcom Limited, whereas the ASMF-PWG2-N35B0 is obsolete. Both components share identical mechanical packaging, color temperature, and optical characteristics (viewing angle and CRI).

Critical differences exist in electrical specifications:

• The ASMF-PWG8-NMPBM operates at 3.2V forward voltage versus 6.3V for the main part
• The ASMF-PWG8-NMPBM requires 300mA test current versus 150mA for the main part
• The ASMF-PWG8-NMPBM delivers higher luminous flux (115lm typical) and efficiency (120 lm/W)
• The ASMF-PWG8-NMPBM exhibits higher thermal resistance (18°C/W versus 10°C/W)

Selection of the ASMF-PWG8-NMPBM requires circuit redesign to accommodate the lower forward voltage and higher current requirements. The substitute is suitable for applications where the power supply and current-limiting circuitry can be adapted to the alternative electrical specifications. The active product status of the ASMF-PWG8-NMPBM provides supply chain continuity and long-term availability assurance.

Frequently Asked Questions (FAQ)

Q: Can the ASMF-PWG8-NMPBM be used as a direct drop-in replacement for the ASMF-PWG2-N35B0?

A: No. While both components share identical mechanical packaging and optical properties, the electrical specifications differ significantly. The ASMF-PWG8-NMPBM operates at 3.2V forward voltage and 300mA test current, compared to 6.3V and 150mA for the ASMF-PWG2-N35B0. Circuit modification is required to accommodate these differences.

Q: What are the key parameters that must match for substitution?

A: Color and CCT (3000K warm white), package type (1212/3030 Metric), mounting method (surface mount), viewing angle (120°), and color rendering index (80) must remain constant. Electrical parameters (voltage, current, flux) may vary based on application circuit capability.

Q: Why does the ASMF-PWG8-NMPBM have higher thermal resistance despite higher efficiency?

A: Thermal resistance is a package-level characteristic determined by die size, substrate material, and thermal path design. The ASMF-PWG8-NMPBM's higher thermal resistance (18°C/W) reflects its specific package construction, independent of luminous efficiency. Thermal management design must account for this specification.

Q: Is the ASMF-PWG8-NMPBM suitable for all applications currently using the ASMF-PWG2-N35B0?

A: Suitability depends on circuit design flexibility. Applications with fixed voltage supplies (6.3V) and current-limiting designs (150mA) cannot accommodate the ASMF-PWG8-NMPBM without modification. Applications with adjustable or lower voltage supplies and higher current capacity can be adapted to use the substitute.

Q: What is the inventory status for these components?

A: The ASMF-PWG2-N35B0 has 945 pieces in stock as new original inventory. The ASMF-PWG8-NMPBM has 913 pieces in stock as new original inventory. Availability should be confirmed with the supplier for long-term procurement planning.
