Equivalent & Substitute Parts for PM3BCW6

Part Overview

The PM3BCW6 is a panel-mounted LED indicator featuring dual green and red LEDs with diffused lens, manufactured by Bivar Inc. This component is classified as obsolete, necessitating identification of alternative parts for ongoing system support and procurement. The PM3BCW6 provides visual status indication through separate green (2.1V, 30mA) and red (2V, 30mA) LED elements with 6-inch wire leads, suitable for 3mm panel cutout applications.

Substitute Part Grouping Explanation

Substitution for the PM3BCW6 follows strict electrical and mechanical equivalency criteria. All substitute parts must satisfy the following requirements: dual green and red LED configuration, round panel cutout shape with 0.16" (4.06mm) dimensions, 3mm T-1 lens form factor, round domed lens style, matching wavelength ranges (568nm green, 625nm red target), and 6-inch wire lead termination.

Two distinct substitution categories apply:

Direct Parametric Equivalents (PM3BCW6.0, PM3BCW6.0-CC2): These parts maintain identical mechanical form factors, lens specifications, and wavelength characteristics. The primary distinction is reduced current rating (20mA versus 30mA), which represents a component-level parameter change while preserving circuit compatibility for applications designed within lower current thresholds.

Similar Mechanical Equivalents (5583001001F): This Dialight component provides identical panel mounting geometry, lens size, and lead configuration. Parameter variations include expanded viewing angle (200° versus 45°), different wavelength characteristics (565nm green, 630nm red), and modified millicandela ratings (8.7mcd green, 5.6mcd red). These differences require circuit-level validation for brightness and angular distribution compatibility.

Engineering Selection Recommendations

PM3BCW6.0 and PM3BCW6.0-CC2: These Bivar Inc. parts represent the primary substitutes for obsolete PM3BCW6 applications. Both are classified as active products with ROHS3 compliance, providing long-term procurement viability. The 20mA current rating (versus original 30mA) requires verification that circuit drive capability accommodates the reduced current specification. Mechanical and optical parameters are identical, ensuring direct panel mounting compatibility without design modification.

5583001001F: The Dialight Series 558 component offers mechanical compatibility but introduces optical parameter variations. The 200° viewing angle contrasts with the original 45° specification, affecting angular light distribution characteristics. Millicandela and wavelength differences require validation against brightness and color perception requirements. This part is suitable for applications where expanded viewing angle provides functional benefit.

All substitute candidates maintain ROHS3 compliance and Moisture Sensitivity Level 1 classification, supporting applications with standard environmental requirements. Procurement selection depends on current drive capability constraints and specific viewing angle requirements for intended installation environment.

Frequently Asked Questions (FAQ)

Q: Can PM3BCW6.0 or PM3BCW6.0-CC2 directly replace PM3BCW6 without circuit modification? A: These parts accommodate direct substitution if the driving circuit can operate within the 20mA current specification. If original circuit design assumes 30mA current draw, circuit-level current limiting adjustment may be necessary.

Q: What is the primary difference between PM3BCW6.0 and PM3BCW6.0-CC2? A: Both parts share identical electrical and optical specifications. The suffix designations reflect internal manufacturing or quality tracking variations without impact to functional parameters or compatibility.

Q: Is the 5583001001F from Dialight a suitable replacement? A: The Dialight 5583001001F provides mechanical panel mounting compatibility with identical cutout dimensions and lens form factor. However, the 200° viewing angle differs significantly from the original 45° specification, and millicandela/wavelength characteristics vary. Selection requires validation that the expanded viewing angle and modified brightness do not compromise intended application requirements.

Q: Can substitutes be mixed within a single application? A: Applications requiring consistent optical behavior across multiple LED indicators should standardize on a single part number. Mixing Bivar PM3BCW6.0/PM3BCW6.0-CC2 with Dialight 5583001001F introduces viewing angle inconsistency and potential visual perception differences.

Q: Are all substitute parts available in equivalent quantities? A: Inventory availability varies: PM3BCW6.0 reports 1320 units, PM3BCW6.0-CC2 reports 776 units, and 5583001001F reports 2077 units. Long-term procurement planning should account for original obsolete part inventory (870 units) depletion and substitute part stock levels.

Q: What compliance certifications apply to these parts? A: PM3BCW6.0, PM3BCW6.0-CC2, and 5583001001F all carry ROHS3 compliance and EAR99 ECCN classification. All components are classified as HTSUS 8541.41.0000 and carry Moisture Sensitivity Level 1 rating.
