Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PM5BWCW13 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Lamp Color: Blue
• Lens Color: Colorless
• Lens Transparency: Clear
• Voltage (Vf): 4V
• Current (If Max): 25mA
• Lens Size: 5mm, T-1 3/4
• Lens Style: Round with Domed Top
• Panel Cutout Shape: Round
• Panel Cutout Dimensions: 0.25" (6.35mm)
• Viewing Angle: 20°
• Wavelength - Peak: 430nm
• Termination Style: Wire Leads - 13" (330.20mm)

Allowable Variation:

• Millicandela Rating: The substitute part PM5BWCW13.0 operates at 25mcd compared to the original 30mcd. This represents a 17% reduction in luminous intensity. This variation is acceptable when the application does not require maximum brightness and the reduced intensity remains sufficient for visual indication purposes.

The substitute part PM5BWCW13.0 meets all mandatory matching criteria and differs only in luminous intensity, making it a valid functional equivalent for applications where the lower brightness level is acceptable.

Engineering Selection Recommendations

Primary Substitute: PM5BWCW13.0

The PM5BWCW13.0 is the direct substitute for the obsolete PM5BWCW13. Selection of this part is based on the following engineering factors:

1. Product Status: The PM5BWCW13.0 carries active product status, ensuring ongoing availability and supply chain reliability compared to the obsolete PM5BWCW13.

2. Electrical Compatibility: Both parts operate at identical voltage (4V) and current (25mA) specifications, ensuring direct circuit compatibility without modification to existing designs.

3. Mechanical Compatibility: Identical lens dimensions (5mm, T-1 3/4), panel cutout specifications (0.25" round), and wire lead length (13") ensure drop-in replacement capability in existing mechanical assemblies.

4. Optical Compatibility: Matching lamp color (blue), lens color (colorless), transparency (clear), viewing angle (20°), and peak wavelength (430nm) preserve the intended visual indication function.

5. Compliance: The PM5BWCW13.0 is ROHS3 compliant, meeting current environmental and regulatory requirements for new production and repair applications.

6. Luminous Intensity Consideration: The PM5BWCW13.0 operates at 25mcd compared to the original 30mcd. This 17% reduction in brightness is acceptable for applications where the indicator function does not depend on maximum luminous intensity. Applications requiring the original 30mcd brightness level must retain the PM5BWCW13 or identify alternative sources.

7. Moisture Sensitivity: Both parts maintain MSL 1 (Unlimited) rating, indicating no moisture sensitivity concerns for storage or handling.

Frequently Asked Questions (FAQ)

Q: Can PM5BWCW13.0 be used as a direct replacement for PM5BWCW13?

A: Yes, PM5BWCW13.0 is a direct substitute for PM5BWCW13 in applications where the reduced luminous intensity (25mcd versus 30mcd) is acceptable. All electrical, mechanical, and optical parameters match except for the 5mcd brightness reduction. No circuit modifications or mechanical changes are required.

Q: What is the significance of the luminous intensity difference between the two parts?

A: The PM5BWCW13 delivers 30mcd while PM5BWCW13.0 delivers 25mcd, representing a 17% reduction in brightness. For most indicator applications, this reduction is imperceptible to the human eye and does not affect functional performance. However, applications requiring maximum brightness or operation in high ambient light conditions should evaluate whether the lower intensity remains adequate for the intended use.

Q: Are there any packaging differences between PM5BWCW13 and PM5BWCW13.0?

A: The PM5BWCW13 is listed with packaging designation "-" (not specified), while PM5BWCW13.0 is supplied in Bag packaging. This difference affects only the delivery format and does not impact component performance or compatibility.

Q: What is the product status difference, and why does it matter?

A: PM5BWCW13 is classified as obsolete, meaning Bivar Inc. no longer manufactures or actively supports this part. PM5BWCW13.0 is active, ensuring continued availability, technical support, and supply chain reliability. For new designs and ongoing production, PM5BWCW13.0 is the recommended choice.

Q: Does PM5BWCW13.0 meet current environmental compliance standards?

A: Yes, PM5BWCW13.0 is ROHS3 compliant, meeting current environmental and regulatory requirements. The original PM5BWCW13 does not specify RoHS compliance status. For applications subject to environmental regulations or customer requirements, PM5BWCW13.0 is the appropriate selection.

Q: Are the wire leads identical between both parts?

A: Yes, both parts feature wire leads with 13" (330.20mm) length, ensuring identical electrical connection and circuit board layout compatibility.

Q: Can these parts be used interchangeably in existing assemblies?

A: Yes, PM5BWCW13.0 can replace PM5BWCW13 in existing assemblies without modification to the circuit board, panel cutout, or wiring. The identical mechanical and electrical specifications ensure drop-in compatibility.

Q: What viewing angle do these parts provide?

A: Both parts provide a 20° viewing angle, meaning the LED output is optimized for visibility within a 20° cone from the optical axis. This narrow viewing angle is typical for panel-mounted indicator applications requiring directional visibility.

Q: Are there moisture sensitivity concerns with these parts?

A: No, both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity. These components do not require special moisture control during storage, handling, or assembly.
