Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6861432144F is determined by the following critical parameters:

Electrical Compatibility: Voltage rating (24V DC) and lamp color (blue) are mandatory matching criteria. The substitute part must operate at the same nominal voltage to ensure direct circuit compatibility without modification.

Mechanical Compatibility: Panel cutout shape (round) and cutout dimensions (0.65" / 16.51mm) determine physical fit within the panel aperture. The lens style (round with domed top) establishes the visual appearance and light distribution characteristics.

Optical Performance: Viewing angle and millicandela rating define the brightness and directional light output. These parameters may vary within acceptable ranges depending on application requirements.

Termination: The original part uses solder lug termination. Substitute parts may employ alternative termination methods (such as quick connect) provided the electrical connection is functionally equivalent and compatible with the circuit design.

Regulatory Compliance: RoHS3 compliance and REACH unaffected status ensure environmental and regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

The APEM Inc. Q16P1BXXB24E serves as a functional substitute for the obsolete Dialight 6861432144F based on the following criteria:

Voltage and Color Match: Both components operate at 24V DC with blue lamp color, ensuring direct electrical compatibility in the circuit.

Mechanical Fit: Panel cutout dimensions are within 0.02" (0.51mm) tolerance, permitting installation in the same panel aperture with minimal modification.

Regulatory Compliance: The Q16P1BXXB24E maintains ROHS3 compliance and REACH unaffected status, meeting the same environmental standards as the original component.

Product Availability: The substitute part is classified as active with confirmed inventory, providing long-term supply assurance compared to the obsolete original.

Design Considerations: The substitute exhibits lower current consumption (20mA vs. 30mA), wider viewing angle (100° vs. 30°), and reduced brightness (540mcd vs. 5400mcd). These differences require evaluation against specific application requirements. The termination method differs (quick connect vs. solder lug), necessitating circuit board modification or adapter implementation.

Frequently Asked Questions (FAQ)

Q: Can the Q16P1BXXB24E directly replace the 6861432144F without circuit modification?

A: Electrical compatibility is confirmed at 24V DC with matching blue lamp color. However, termination style differs (quick connect vs. solder lug), requiring either circuit board rework or a termination adapter. Panel cutout dimensions are within tolerance for mechanical fit.

Q: What are the optical performance differences between these components?

A: The original 6861432144F provides 5400mcd brightness with a 30° viewing angle, creating a concentrated light output. The substitute Q16P1BXXB24E delivers 540mcd brightness with a 100° viewing angle, distributing light over a wider area. Application requirements determine which optical profile is acceptable.

Q: Does the lower current rating of the substitute affect circuit design?

A: The Q16P1BXXB24E operates at 20mA compared to the original 30mA rating. This reduction may lower power dissipation and heat generation. Verify that the circuit's current-limiting resistor or driver is compatible with the lower current requirement.

Q: Is the IP67 rating of the substitute an advantage?

A: The Q16P1BXXB24E includes IP67 ingress protection, whereas the original part does not specify this rating. IP67 protection provides enhanced resistance to dust and moisture, which may be beneficial in harsh environments but is not required for direct substitution.

Q: What is the impact of the lens size difference?

A: The original component features an 18.00mm diameter lens, while the substitute has a 10.00mm diameter lens. This affects the visual appearance and light distribution pattern. Panel aesthetics and light diffusion characteristics should be evaluated for the specific application.

Q: Are both components RoHS3 compliant?

A: Yes, both the 6861432144F and Q16P1BXXB24E are ROHS3 compliant and REACH unaffected, meeting current environmental regulations for electronic components.
