Bivar PM3BCW8 LED Panel Indicator - Equivalent & Substitute Parts

Part Overview

The Bivar PM3BCW8 is a 3mm LED panel indicator assembly with dual green and red diffused lenses and 6-inch wire leads. This part is classified as obsolete, necessitating identification of active alternative components that maintain electrical and mechanical compatibility for system-level substitution. The PM3BCW8 serves as a visual indicator in panel-mounted applications requiring dual-color feedback with specified voltage and current characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are qualified based on the following critical parameters that determine electrical and mechanical compatibility:

• Electrical Parameters: Forward voltage (Vf) tolerance within ±0.2V and maximum current (If) rating
• Mechanical Parameters: Panel cutout diameter of 0.16" (4.06mm) and 3mm T-1 lens form factor
• Optical Parameters: Dual green and red color configuration with diffused lens transparency
• Termination: Wire lead configuration and length considerations
• Compliance: RoHS3 compliance and MSL rating

PM3BCW8.0 qualifies as a similar substitute with identical electrical parameters (2.1V/2V, 20mA/20mA) and mechanical mounting. PM3BCW6.0-CC2 qualifies as a parametric equivalent with identical electrical characteristics and 6-inch lead length. The Dialight 5583001001F qualifies as a similar substitute despite differing current ratings (30mA matching) and viewing angle specification (200° vs. 45°), with compatible panel cutout and lens size.

Parameter Comparison

Engineering Selection Recommendations

PM3BCW8.0 (Bivar Inc.): This active substitute carries identical electrical parameters (2.1V/2V forward voltage, 6mcd/6mcd brightness) and mechanical mounting specifications. The primary difference is reduced maximum current rating (20mA vs. 30mA) and extended wire lead length (8" vs. 6"). ROHS3 compliance provides regulatory alignment with modern supply chain requirements. Selection is appropriate for applications within the 20mA operating envelope.

PM3BCW6.0-CC2 (Bivar Inc.): This active parametric equivalent provides identical electrical and optical characteristics with matching 6-inch wire lead length. ROHS3 compliance and confirmed white lens color specification support direct substitution in existing designs. Selection is optimal for applications requiring exact mechanical interchangeability.

5583001001F (Dialight, Series 558): This active substitute maintains matching panel cutout diameter, lens size, and identical current ratings (30mA). Voltage specifications differ marginally (2V/1.9V vs. 2.1V/2V), and the 200° viewing angle extends the field of view compared to the 45° specification of the PM3BCW8. ROHS3 compliance is confirmed. Selection applies to applications requiring wider viewing angle coverage, provided voltage tolerance accommodates the ±0.1V reduction in red forward voltage.

Frequently Asked Questions (FAQ)

Q: Can PM3BCW8.0 directly replace PM3BCW8 in existing designs? A: PM3BCW8.0 is electrically compatible but operates at reduced maximum current (20mA vs. 30mA). Design review is required to confirm operation remains within the 20mA specification for both green and red LEDs. Wire lead length differs at 8" versus 6".

Q: What is the primary difference between PM3BCW8.0 and PM3BCW6.0-CC2? A: PM3BCW6.0-CC2 provides identical electrical characteristics and wire lead length (6") to the original PM3BCW8, differing only in product designation. Both operate at 20mA maximum current. PM3BCW6.0-CC2 explicitly specifies white lens color, matching the original specification.

Q: Is the Dialight 5583001001F compatible with the PM3BCW8? A: The Dialight part maintains mechanical compatibility (panel cutout, lens size, current rating) but introduces differences in forward voltage tolerance (2V/1.9V), wavelength (565nm/630nm vs. 568nm/625nm), and viewing angle (200° vs. 45°). Application-level design review is required to confirm these optical and electrical differences do not impact system performance.

Q: How do wire lead lengths affect substitution? A: The original PM3BCW8 specifies 6-inch leads. PM3BCW8.0 provides 8-inch leads, while PM3BCW6.0-CC2 maintains 6-inch leads. Lead length modifications may require panel wiring redesign or harness rework depending on physical layout constraints.

Q: What compliance certifications are relevant for substitute selection? A: All active substitute parts carry ROHS3 compliance certification. The original PM3BCW8 does not specify ROHS status due to obsolete product classification. MSL rating of 1 (Unlimited) applies uniformly across all parts, indicating no moisture sensitivity constraints.

Q: Are there current rating implications when substituting from 30mA to 20mA operation? A: PM3BCW8.0 and PM3BCW6.0-CC2 reduce maximum current from 30mA to 20mA for both green and red LEDs. Circuit design must confirm operation occurs within the 20mA envelope. If 30mA operation is required, the Dialight 5583001001F maintains this specification.
