Substitute Part Grouping Explanation

Substitute parts for the ASMT-UWB2-ZW7F2 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Compatibility Criteria:

• Package / Case: 2-PLCC (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Size / Dimension: 3.20mm L x 2.80mm W (exact match required)
• Height (Max): 2.10mm (exact match required)
• Manufacturer: Broadcom Limited (same manufacturer ensures design consistency)
• Color: White or White-based variants (functional equivalence for indication purposes)

Substitution Logic: The ASMT-UWB2-ZW7F2 is obsolete; therefore, active product alternatives within the same 2-PLCC package family are identified as direct substitutes. Substitute parts maintain identical mechanical dimensions and mounting characteristics, ensuring drop-in compatibility in existing PCB layouts. Color variants within the white spectrum are acceptable as they serve the same indication function.

Parameter Comparison

Engineering Selection Recommendations

ASMT-UWB2-ZX3F2 (MFR Recommended Substitute): This part is the manufacturer-recommended alternative to the obsolete ASMT-UWB2-ZW7F2. It maintains identical mechanical and package specifications while offering active product status. The ASMT-UWB2-ZX3F2 is ROHS3 compliant and specifies MSL 3 (168 Hours), providing defined moisture handling requirements. The neutral white color variant (4000K) is functionally equivalent for indication applications. This substitute is the primary choice for new designs and production transitions.

ASMT-UWA1-ZX3B2 (Parametric Equivalent): This part provides parametric equivalence through identical package, mounting type, and physical dimensions. It is active and ROHS3 compliant. The ASMT-UWA1-ZX3B2 differs in base product number (ASMT-UWA1 versus ASMT-UWB2) and configuration designation (Standard). This part serves as a secondary alternative when the manufacturer-recommended substitute is unavailable.

Frequently Asked Questions (FAQ)

Q: Can ASMT-UWB2-ZX3F2 be used as a direct replacement for ASMT-UWB2-ZW7F2? A: Yes. Both parts share identical 2-PLCC package specifications, surface mount mounting type, and physical dimensions (3.20mm L x 2.80mm W, 2.10mm height). The ASMT-UWB2-ZX3F2 is the manufacturer-recommended substitute and provides drop-in compatibility.

Q: What is the difference between the white and neutral white color variants? A: The ASMT-UWB2-ZX3F2 specifies a dominant wavelength of 4000K (neutral white), while the original ASMT-UWB2-ZW7F2 does not specify wavelength data. Both serve white LED indication functions. Color perception differences are minimal in typical indication applications.

Q: Is ASMT-UWA1-ZX3B2 compatible with existing PCB layouts designed for ASMT-UWB2-ZW7F2? A: Yes. The ASMT-UWA1-ZX3B2 maintains identical package dimensions and mounting specifications, ensuring mechanical and electrical compatibility with existing PCB designs.

Q: What are the compliance differences between the substitute parts? A: Both active substitutes (ASMT-UWB2-ZX3F2 and ASMT-UWA1-ZX3B2) are ROHS3 compliant. The ASMT-UWB2-ZX3F2 specifies MSL 3 (168 Hours), while the ASMT-UWA1-ZX3B2 does not specify MSL data. For moisture-sensitive applications, the ASMT-UWB2-ZX3F2 provides defined handling requirements.

Q: Why is the original ASMT-UWB2-ZW7F2 marked as obsolete? A: Obsolete status indicates the part is no longer manufactured or supported by Broadcom Limited. Active alternatives within the same product family are available for design transitions and production continuity.
