Bulgin DX1093/TR LED Panel Indicator - Equivalent & Substitute Parts

Part Overview

The Bulgin DX1093/TR is an LED panel indicator featuring tri-color capability (Amber, Green, Red) with a 2.4V forward voltage rating and 30mA maximum current per color. This component is designed for panel-mount applications requiring visual status indication with IP66 ingress protection. The part maintains Active product status and is ROHS3 compliant, making it suitable for current industrial and commercial applications. Alternative models within the Bulgin DX series provide equivalent functionality with variations in electrical ratings, enabling selection based on specific circuit current requirements and design constraints.

Substitute Part Grouping Explanation

Substitution eligibility for the DX1093/TR is determined by the following critical parameters that must remain constant across equivalent parts:

Lamp Color Configuration: Tri-color (Amber, Green, Red)
Forward Voltage: 2.4V across all color channels
Panel Cutout Dimensions: 0.315" (8.00mm) round opening
Lens Size and Style: 5mm T-1 3/4 with round domed top
Termination Style: PC Pin
Ingress Protection Rating: IP66
Millicandela Rating: 2.5mcd per color

The substitute parts DX1090/TR and DX1091/TR maintain identical specifications in all parameters listed above. The primary distinction between these parts and the DX1093/TR lies in the Maximum Current (If) rating, which varies as a design parameter within the same mechanical and optical envelope. This current rating variation allows circuit designers to select the appropriate part based on available drive current from their control circuitry while maintaining full mechanical and optical compatibility.

Engineering Selection Recommendations

All three parts—DX1093/TR, DX1090/TR, and DX1091/TR—maintain Active product status with ROHS3 compliance and identical Moisture Sensitivity Level (MSL 1). Selection between these parts is determined solely by circuit current requirements:

DX1090/TR (10mA maximum): Select when drive circuitry provides limited current capacity or when power consumption minimization is required.
DX1093/TR (30mA maximum): Select for standard applications requiring full brightness output at nominal current levels.
DX1091/TR (30mA maximum): Functionally equivalent to DX1093/TR with identical current rating and brightness characteristics.

All substitute parts share identical mechanical mounting, optical properties, electrical voltage characteristics, and environmental protection ratings. Direct substitution is permissible when the circuit's current-sourcing capability matches or exceeds the selected part's maximum current rating.

Frequently Asked Questions (FAQ)

Q: Can DX1090/TR replace DX1093/TR in an existing design?

A: Yes, provided the circuit's current-limiting resistor is adjusted to supply no more than 10mA per color channel. The DX1090/TR is mechanically and optically identical to the DX1093/TR, differing only in maximum current rating. Brightness output will be proportional to the applied current.

Q: Are DX1091/TR and DX1093/TR interchangeable?

A: Yes. Both parts have identical electrical ratings (2.4V, 30mA), mechanical dimensions (8.00mm round cutout), lens specifications (5mm T-1 3/4), and environmental protection (IP66). They are direct functional equivalents.

Q: What determines whether a substitute part is compatible?

A: Compatibility is determined by matching the following parameters: tri-color lamp configuration, 2.4V forward voltage, 8.00mm round panel cutout, 5mm T-1 3/4 lens, PC Pin termination, IP66 ingress protection, and 2.5mcd brightness per color. Maximum current rating must be supported by the circuit design.

Q: Does changing from DX1093/TR to DX1090/TR affect panel mounting?

A: No. Both parts use identical 8.00mm round panel cutout dimensions and PC Pin termination. No mechanical modification to the panel or circuit board is required.

Q: Are all three parts ROHS3 compliant?

A: Yes. DX1093/TR, DX1090/TR, and DX1091/TR are all ROHS3 compliant with MSL 1 rating, meeting current environmental and regulatory requirements.
