PM3BCW12-CC2 Equivalent & Substitute Parts

Part Overview

The PM3BCW12-CC2 is a panel-mounted LED indicator assembly manufactured by Bivar Inc., featuring dual-color (green and red) diffused lenses with 12-inch wire leads. This component is classified as obsolete, indicating that direct procurement from the original manufacturer may be limited or unavailable. The part operates at 2.1V forward voltage for green and 2V for red, with a maximum current rating of 30mA for both colors. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PM3BCW12-CC2 are identified based on strict alignment with the following critical parameters:

Primary Compatibility Criteria:

• Dual-color LED configuration (green and red)
• 3mm T-1 lens size
• Round panel cutout shape with 0.16" (4.06mm) dimensions
• Round lens style with domed top
• Wire lead termination
• Forward voltage compatibility (green approximately 2.0-2.1V, red approximately 1.9-2.0V)
• Current rating compatibility (20-30mA range)
• Diffused lens transparency
• Moisture Sensitivity Level 1

Substitution Logic: Two substitute parts meet the established compatibility criteria. The first substitute, PM3BCW12.0-CC2, is a direct variant from the same manufacturer (Bivar Inc.) with identical electrical and mechanical specifications except for a reduced current rating (20mA versus 30mA). The second substitute, 5583001001F, is manufactured by Dialight and maintains the same lens size, panel cutout dimensions, and dual-color configuration, with equivalent current ratings and comparable forward voltages. Both substitutes are classified as active products with current availability.

Parameter Comparison

Engineering Selection Recommendations

PM3BCW12.0-CC2 (Bivar Inc.): This substitute is the preferred choice for direct replacement in applications where the original PM3BCW12-CC2 is no longer available. As an active product from the same manufacturer, it maintains identical mechanical and optical specifications. The primary difference is a reduced maximum current rating of 20mA compared to the original 30mA specification. This part is ROHS3 compliant and carries the same MSL rating. Selection of this substitute is appropriate for designs where the 20mA current rating satisfies circuit requirements.

5583001001F (Dialight): This substitute provides an alternative from a different manufacturer with equivalent mechanical compatibility and current ratings matching the original specification (30mA). The part is ROHS3 compliant and REACH unaffected. Notable differences include a wider viewing angle (200° versus 45°), slightly different wavelength characteristics (565nm green, 630nm red versus 568nm green, 625nm red), and higher green brightness (8.7mcd versus 6mcd). This substitute is suitable for applications where the wider viewing angle and increased brightness are compatible with system requirements.

Both substitutes are active products with established supply availability, providing reliable alternatives to the obsolete PM3BCW12-CC2.

Frequently Asked Questions (FAQ)

Q: Can PM3BCW12.0-CC2 be used as a direct replacement for PM3BCW12-CC2?

A: PM3BCW12.0-CC2 is mechanically and optically compatible with PM3BCW12-CC2. The primary difference is the maximum current rating: 20mA for PM3BCW12.0-CC2 versus 30mA for PM3BCW12-CC2. Direct substitution is possible if circuit design operates at or below 20mA for both green and red LEDs.

Q: What are the key differences between the two substitute parts?

A: PM3BCW12.0-CC2 is manufactured by Bivar Inc. (same as the original) with identical voltage and wavelength specifications but reduced current rating. 5583001001F is manufactured by Dialight with equivalent current ratings but features a 200° viewing angle instead of 45°, higher green brightness (8.7mcd), and slightly different wavelength characteristics.

Q: Are both substitute parts RoHS compliant?

A: Yes, both PM3BCW12.0-CC2 and 5583001001F are ROHS3 compliant. The original PM3BCW12-CC2 RoHS status is not specified in available documentation.

Q: Does the viewing angle difference affect mechanical compatibility?

A: No. Both substitute parts maintain the same 3mm T-1 lens size, 0.16" (4.06mm) panel cutout dimensions, and round domed lens style. The viewing angle difference affects light distribution characteristics but not physical panel mounting compatibility.

Q: What is the impact of the 20mA current rating on PM3BCW12.0-CC2?

A: The reduced current rating of 20mA requires circuit design verification to ensure that LED drive current does not exceed this specification. If the original design operates at 30mA, circuit modification may be necessary to reduce current to 20mA or below.

Q: Is termination style compatible across all three parts?

A: PM3BCW12-CC2 and PM3BCW12.0-CC2 both feature 12-inch wire leads. The termination style for 5583001001F is not specified in available documentation and should be verified before selection.

Q: Can 5583001001F be used in applications requiring a 45° viewing angle?

A: 5583001001F features a 200° viewing angle, which is wider than the 45° specification of the original part. While mechanically compatible, the optical characteristics differ significantly. Selection depends on whether the wider viewing angle is compatible with application requirements.
