Dialight 5503507F LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5503507F is an LED Circuit Board Indicator (CBI) designed for through-hole, right-angle mounting applications. This dual-color LED combines green and red emitters in a single 5mm T-1 3/4 package with a clear, domed lens. The component operates at 2.3V for green and 2.1V for red with a 10mA rated current, delivering 8mcd and 5mcd brightness respectively. The part is Active status and ROHS3 compliant, making it suitable for modern electronic assemblies. Equivalent and substitute parts are identified based on matching electrical characteristics, mechanical form factor, and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5503507F are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

• Dual-color configuration (Green and Red emitters)
• Identical wavelength specifications (565nm Green, 635nm Red)
• Matching current rating (10mA)
• Identical brightness output (8mcd Green, 5mcd Red)
• Identical voltage ratings (2.3V Green, 2.1V Red)
• Matching viewing angle (65°)
• Identical lens type and style (Clear, Round with Domed Top)
• Identical package form factor (5mm, T-1 3/4)
• Through-hole, right-angle mounting configuration
• Active product status
• ROHS3 compliance and REACH unaffected status

The substitute parts listed below meet all these criteria and are direct functional equivalents.

Engineering Selection Recommendations

All three parts—5503507F, 5503505F, and 5503507010F—are functionally equivalent and interchangeable for circuit board indicator applications requiring dual-color LED functionality. Selection between these parts should be based on:

• Availability: 5503505F offers the highest inventory (2717 pcs), followed by 5503507010F (1718 pcs) and 5503507F (841 pcs)
• Supply chain continuity: All parts maintain Active product status with ROHS3 compliance and REACH unaffected certification
• Lead time requirements: Inventory levels indicate relative availability for immediate procurement

No technical differentiation exists between these parts based on the provided specifications. All meet identical electrical, optical, and mechanical requirements for through-hole, right-angle LED circuit board indicator applications.

Frequently Asked Questions (FAQ)

Q: Can 5503505F be used as a direct replacement for 5503507F? A: Yes. Both parts share identical electrical specifications (10mA current, 2.3V/2.1V voltage ratings), optical characteristics (565nm/635nm wavelengths, 8mcd/5mcd brightness), and mechanical form factor (5mm T-1 3/4 through-hole right-angle package). They are direct functional equivalents.

Q: What is the difference between 5503507F and 5503507010F? A: No electrical, optical, or mechanical differences exist between these parts. Both are from the Dialight 550 series with identical specifications. The part number suffix variation reflects internal Dialight product coding but does not indicate functional differences.

Q: Are these parts suitable for new designs? A: Yes. All three parts maintain Active product status with ROHS3 compliance and REACH unaffected certification, making them appropriate for current electronic assembly standards.

Q: What is the significance of the right-angle mounting configuration? A: Right-angle mounting orients the LED leads perpendicular to the lens axis, allowing the indicator to be mounted flush against a circuit board edge with the lens facing outward. This configuration is essential for applications requiring side-mounted status indicators.

Q: Can these parts be used interchangeably in existing assemblies? A: Yes, provided the circuit board layout accommodates the through-hole right-angle lead configuration. All three parts are mechanically and electrically identical, ensuring drop-in compatibility.
