Key Parameters

Substitute Part Grouping Explanation

Substitution of the PM3YCW12.0 is based on electrical and mechanical compatibility within the PM3 series from Bivar Inc. The following parameters must remain constant for valid substitution:

• Manufacturer and series consistency (Bivar Inc., PM3 series)
• Electrical ratings: 2V voltage and 30mA maximum current
• Mechanical compatibility: 3mm T-1 lens size, round panel cutout at 0.16" (4.06mm)
• Termination: 12-inch wire leads
• Wavelength specification: 590nm (yellow emission)
• Moisture sensitivity level: 1 (Unlimited)

Parameters that may vary between the main part and substitutes include lens transparency (clear versus diffused), lens color appearance, millicandela rating, and viewing angle. These variations do not affect electrical or mechanical interchangeability but may impact optical performance characteristics in specific applications.

Parameter Comparison

Engineering Selection Recommendations

The PM3YDW12.0 is the active equivalent substitute for the obsolete PM3YCW12.0. Both components share identical electrical specifications (2V, 30mA), mechanical dimensions, and panel mounting characteristics. The PM3YDW12.0 is currently in active production status with substantial inventory availability (21,903 pieces), ensuring reliable supply chain continuity.

The primary differences between these components are optical characteristics: the PM3YDW12.0 features a diffused yellow lens with a 40° viewing angle and 20mcd brightness rating, compared to the PM3YCW12.0's clear colorless lens with a 30° viewing angle and 40mcd brightness rating. These optical variations do not affect electrical interchangeability or mechanical fit.

The PM3YDW12.0 carries RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution. Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Frequently Asked Questions (FAQ)

Q: Can the PM3YDW12.0 directly replace the PM3YCW12.0 in existing designs?

A: Yes. Both components share identical electrical ratings (2V, 30mA), mechanical dimensions (3mm T-1 lens, 0.16" panel cutout), and 12-inch wire lead termination. Direct mechanical and electrical substitution is supported.

Q: What are the optical differences between these two parts?

A: The PM3YCW12.0 has a clear colorless lens with 40mcd brightness and a 30° viewing angle. The PM3YDW12.0 has a diffused yellow lens with 20mcd brightness and a 40° viewing angle. The diffused lens of the PM3YDW12.0 provides a wider viewing angle but lower peak brightness.

Q: Why is the PM3YCW12.0 listed as obsolete?

A: The PM3YCW12.0 is no longer in active production. The PM3YDW12.0 serves as the active production equivalent within the PM3 series, ensuring continued availability and supply chain support.

Q: Are there any compliance or regulatory differences between these parts?

A: Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. The PM3YDW12.0 carries RoHS3 compliance and REACH unaffected status, meeting current regulatory standards.

Q: What is the moisture sensitivity level for these components?

A: Both the PM3YCW12.0 and PM3YDW12.0 have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without special moisture control requirements.

Q: How do the viewing angles differ, and does this affect application suitability?

A: The PM3YCW12.0 has a 30° viewing angle, while the PM3YDW12.0 has a 40° viewing angle. The wider viewing angle of the PM3YDW12.0 allows the indicator to be visible from a broader range of observation positions. Application suitability depends on specific visibility requirements in the target installation environment.
