LED Panel Indicator PM5ATW12.0 Equivalent & Substitute Parts

Part Overview

The PM5ATW12.0 is an LED panel indicator manufactured by Bivar Inc., designed for applications requiring a 2V, 30mA amber light source with clear lens optics. This component features a 5mm T-1 3/4 lens form factor with 12-inch wire leads and a round panel cutout of 0.25 inches (6.35mm). The part is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PM5ATW12.0 is determined by strict electrical and mechanical compatibility criteria. The following parameters must remain constant across substitute components:

• Manufacturer: Bivar Inc. (same product family)
• Series: PM5 (same mechanical and electrical platform)
• Lamp Color: Amber (same spectral output at 605nm peak wavelength)
• Voltage: 2V (electrical compatibility with circuit design)
• Current: 30mA (current-limiting circuit compatibility)
• Lens Size: 5mm, T-1 3/4 (mechanical fit in existing assemblies)
• Panel Cutout Dimensions: 0.25" (6.35mm) (panel mounting compatibility)
• Termination Style: Wire Leads - 12" (304.80mm) (assembly and routing compatibility)

Parameters that may vary within substitution allowance:

• Lens Transparency (Clear vs. Diffused)
• Lens Color (Colorless vs. Amber)
• Viewing Angle (35° vs. 45°)
• Millicandela Rating (40mcd vs. 25mcd)
• Product Status (Obsolete vs. Active)

Parameter Comparison

Engineering Selection Recommendations

The PM5ADW12.0 is the active equivalent substitute for the obsolete PM5ATW12.0. Both components share identical electrical ratings (2V, 30mA), mechanical form factors (5mm T-1 3/4 lens, 0.25-inch panel cutout), and wire lead termination (12 inches). The PM5ADW12.0 maintains the same 605nm peak wavelength amber spectral output.

The primary differences between these components are:

• Product Status: PM5ADW12.0 is Active, ensuring continued availability and supply chain support, whereas PM5ATW12.0 is Obsolete.
• Lens Transparency: PM5ATW12.0 features a clear lens with colorless lens color; PM5ADW12.0 features a diffused lens with amber lens color. This affects light distribution and perceived brightness.
• Viewing Angle: PM5ATW12.0 provides a 35° viewing angle; PM5ADW12.0 provides a 45° viewing angle, resulting in wider light distribution.
• Millicandela Rating: PM5ATW12.0 delivers 40mcd; PM5ADW12.0 delivers 25mcd. The clear lens of the main part concentrates light output, while the diffused lens of the substitute disperses it.
• Compliance: PM5ADW12.0 is ROHS3 Compliant, supporting regulatory requirements for new designs.

Selection of PM5ADW12.0 is appropriate for applications where the diffused amber lens and wider viewing angle are compatible with system requirements. Applications requiring the concentrated light output and narrow viewing angle of the clear lens may require alternative sourcing strategies.

Frequently Asked Questions (FAQ)

Q: Can PM5ADW12.0 directly replace PM5ATW12.0 in existing assemblies?

A: Mechanical and electrical compatibility is confirmed. Both components mount identically in 0.25-inch (6.35mm) round panel cutouts and operate at 2V, 30mA. However, optical performance differs due to lens transparency and color differences. The PM5ADW12.0 produces a diffused amber light with a 45° viewing angle and 25mcd output, compared to the PM5ATW12.0's clear lens with 35° viewing angle and 40mcd output. Compatibility depends on whether the application tolerates these optical differences.

Q: What is the significance of the lens transparency difference?

A: The PM5ATW12.0 features a clear lens that concentrates light output into a narrower beam (35° viewing angle, 40mcd). The PM5ADW12.0 features a diffused lens that disperses light over a wider area (45° viewing angle, 25mcd). Clear lenses are suitable for applications requiring focused, high-intensity indication; diffused lenses are suitable for applications requiring broad, uniform illumination.

Q: Why is PM5ADW12.0 listed as Active while PM5ATW12.0 is Obsolete?

A: Product status reflects manufacturer support and availability. The PM5ATW12.0 has been discontinued by Bivar Inc., making it unavailable for new orders. The PM5ADW12.0 remains in active production, ensuring supply chain continuity and support for ongoing applications.

Q: Are there compliance differences between these components?

A: PM5ADW12.0 is specified as ROHS3 Compliant. Compliance information for PM5ATW12.0 is not provided in the available data. For applications subject to RoHS regulations, PM5ADW12.0 is the appropriate selection.

Q: How do the millicandela ratings affect application performance?

A: Millicandela (mcd) measures luminous intensity. The PM5ATW12.0 delivers 40mcd with a clear lens and 35° viewing angle, concentrating light output. The PM5ADW12.0 delivers 25mcd with a diffused lens and 45° viewing angle, distributing light over a wider area. Applications requiring maximum brightness in a narrow beam should evaluate whether the 25mcd output of PM5ADW12.0 is sufficient.

Q: Are the wire lead lengths identical?

A: Yes. Both PM5ATW12.0 and PM5ADW12.0 feature 12-inch (304.80mm) wire leads, ensuring identical routing and assembly compatibility.
