Substitute Part Grouping Explanation

The PM3BWDW6 has one identified substitute within the Bivar Inc. PM3 series: the PM3BWDW12.0. This substitution is valid based on the following criteria:

Matching Electrical Specifications:

• Voltage: 4V (identical)
• Current: 25mA (identical)

Matching Optical Specifications:

• Lamp Color: Blue (identical)
• Lens Color: Blue (identical)
• Lens Transparency: Diffused (identical)
• Viewing Angle: 40° (identical)
• Wavelength - Peak: 430nm (identical)
• Millicandela Rating: 10mcd (identical)

Matching Mechanical Specifications:

• Lens Size: 3mm, T-1 (identical)
• Panel Cutout Shape: Round (identical)
• Panel Cutout Dimensions: 0.16" (4.06mm) (identical)
• Termination Style: Wire Leads (identical)

Variable Parameter:

• Wire Lead Length: PM3BWDW6 provides 6" leads; PM3BWDW12.0 provides 12" leads

The primary difference between these parts is the wire lead length. The PM3BWDW12.0 is suitable as a substitute when the extended 12-inch lead length accommodates the application's physical layout requirements.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement:

The PM3BWDW6 is classified as obsolete. The PM3BWDW12.0 is the recommended substitute, as it maintains active product status with Bivar Inc. and carries ROHS3 compliance certification, whereas the original part has undefined REACH status.

Lead Length Consideration:

The primary engineering decision point is wire lead length. The PM3BWDW12.0 provides 12-inch leads compared to the 6-inch leads of the PM3BWDW6. This substitution is appropriate when:

• The application's physical layout accommodates the extended lead length
• The additional wire length does not introduce routing or mechanical constraints
• The longer leads provide improved flexibility for panel-mount positioning

Compliance Status:

The PM3BWDW12.0 carries explicit ROHS3 compliance and REACH Unaffected status, providing superior regulatory documentation compared to the obsolete PM3BWDW6.

Frequently Asked Questions (FAQ)

Q: Can the PM3BWDW12.0 directly replace the PM3BWDW6 in existing designs?

A: Yes, provided the 12-inch wire lead length is compatible with the application's physical layout. All electrical and optical specifications are identical. The panel cutout dimensions and mounting requirements remain unchanged.

Q: What is the primary difference between these two parts?

A: The wire lead length is the only difference. The PM3BWDW6 provides 6-inch leads, while the PM3BWDW12.0 provides 12-inch leads. All other specifications—voltage, current, color, viewing angle, lens size, and optical output—are identical.

Q: Why is the PM3BWDW6 obsolete?

A: The PM3BWDW6 is classified as obsolete by Bivar Inc. The PM3BWDW12.0 is the active product within the PM3 series with identical electrical and optical characteristics.

Q: Are there any compliance differences between these parts?

A: Yes. The PM3BWDW12.0 carries ROHS3 compliance certification and REACH Unaffected status. The PM3BWDW6 has undefined REACH status. Both parts share the same ECCN (EAR99) and HTSUS classification.

Q: What is the Moisture Sensitivity Level for these parts?

A: Both the PM3BWDW6 and PM3BWDW12.0 have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Can I use the PM3BWDW12.0 in applications requiring shorter leads?

A: The PM3BWDW12.0 can be used in applications requiring shorter leads; however, excess wire length must be managed through routing or trimming as appropriate for the specific application design.

Q: Are the optical specifications identical between these parts?

A: Yes. Both parts feature blue diffused lenses with 40° viewing angles, 10mcd brightness, 430nm peak wavelength, and 3mm T-1 lens size.
