Substitute Part Grouping Explanation
Substitution eligibility for the 3BWD-201 is determined by strict equivalence across the following critical parameters:
Electrical Compatibility Parameters:
- Forward voltage (Vf): 4V nominal
- Test current: 20mA
- Peak wavelength: 430nm (blue spectrum)
- Millicandela rating: 10mcd
Mechanical Compatibility Parameters:
- Lens size: 3mm T-1 form factor
- Lens color and transparency: Blue diffused
- Mounting type: Through hole radial configuration
- Package type: Radial
Environmental & Compliance Parameters:
- Moisture Sensitivity Level: 1 (Unlimited)

Engineering Selection Recommendations
The 3BWD-F serves as the direct parametric equivalent for the obsolete 3BWD-201. Selection of the 3BWD-F is supported by:
Product Status Consideration: The 3BWD-F maintains Active product status, ensuring ongoing availability and supply chain continuity compared to the Obsolete 3BWD-201.
Compliance Alignment: Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, maintaining regulatory compliance for existing applications.
Electrical & Optical Equivalence: All critical electrical parameters (4V forward voltage, 20mA test current, 10mcd brightness) and optical specifications (430nm peak wavelength, 35° viewing angle, blue diffused lens) are identical between the main part and substitute.
Mechanical Compatibility: The 3mm T-1 through-hole radial package format is identical. The maximum height difference (5.30mm vs. 5.10mm) represents a 0.20mm increase and does not affect standard PCB layout or mechanical clearance requirements for typical LED indicator applications.
Moisture Sensitivity: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints during storage or handling.
Frequently Asked Questions (FAQ)
Q: Can the 3BWD-F directly replace the 3BWD-201 in existing circuit designs?
A: Yes. The 3BWD-F matches all electrical parameters (4V forward voltage, 20mA test current) and optical specifications (10mcd, 430nm peak wavelength, 35° viewing angle) required for the 3BWD-201. The through-hole radial package format and 3mm T-1 lens form factor are identical, enabling direct PCB footprint compatibility.
Q: What is the significance of the height difference between these parts?
A: The 3BWD-F has a maximum height of 5.30mm compared to 5.10mm for the 3BWD-201, a difference of 0.20mm. This minor variation does not affect standard LED indicator applications and remains within typical mechanical clearance tolerances for through-hole component placement.
Q: Why is the 3BWD-201 listed as Obsolete?
A: Obsolete status indicates the manufacturer has discontinued production of this part number. The 3BWD-F, carrying Active status, represents the current production equivalent and ensures long-term supply availability.
Q: Are there packaging differences between these parts?
A: The 3BWD-201 uses standard packaging, while the 3BWD-F is available in Bulk packaging format. Both contain identical components; packaging format affects order quantity and handling but not electrical or mechanical performance.
Q: Do both parts meet the same compliance standards?
A: Yes. Both the 3BWD-201 and 3BWD-F share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, maintaining regulatory compliance for export and trade purposes.
Q: Is moisture sensitivity a consideration for these LED indicators?
A: No. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints. Standard storage and handling procedures apply without special environmental controls.
