LED Circuit Board Indicator 5505207F Equivalent & Substitute Parts

Part Overview

The Dialight 5505207F is an active LED circuit board indicator designed for through-hole, right-angle mounting applications. This single green diffused LED operates at 2.2V with a 20mA current rating and delivers 34mcd brightness output. The component features a 5mm T-1 3/4 round domed lens with a 50° viewing angle, making it suitable for standard PCB indicator applications requiring reliable green status signaling. Finding equivalent parts may be necessary due to inventory constraints, supply chain considerations, or design flexibility requirements while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5505207F is determined by strict alignment with the following critical parameters:

• Electrical Compatibility: Voltage rating (2.2V) and current rating (20mA) must match exactly
• Optical Characteristics: Green color specification with wavelength in the 560–570nm range
• Mechanical Compatibility: 5mm T-1 3/4 lens size, round domed top configuration, through-hole right-angle mounting
• Configuration: Single LED element only
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status required

The Lumex Opto/Components Inc. SSF-LXH100LGD meets all substitution criteria. Both parts share identical voltage, current, mounting configuration, and physical form factor. Minor variations in wavelength peak (565nm vs. 563nm) and viewing angle (60° vs. 50°) remain within acceptable tolerance for standard indicator applications, as both fall within the green spectrum and provide adequate visibility for circuit board indication purposes.

Parameter Comparison

Engineering Selection Recommendations

Both the Dialight 5505207F and Lumex SSF-LXH100LGD are active products with full ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component deployment. Selection between these parts should be based on availability, lead time, and cost considerations, as both satisfy the electrical and mechanical requirements for standard green LED circuit board indicator applications. The SSF-LXH100LGD offers a wider 60° viewing angle compared to the 5505207F's 50° angle, which may provide improved visibility in certain mounting orientations. The 4mcd difference in brightness (34mcd vs. 30mcd) is negligible for typical indicator applications and does not affect functional performance in standard circuit board signaling contexts.

Frequently Asked Questions (FAQ)

Q: Can the SSF-LXH100LGD replace the 5505207F in existing designs?

A: Yes. Both parts share identical voltage (2.2V), current (20mA), lens size (5mm T-1 3/4), and mounting configuration (through-hole right-angle). The parts are electrically and mechanically compatible for direct substitution in PCB layouts designed for the 5505207F.

Q: What is the significance of the wavelength difference between 563nm and 565nm?

A: Both wavelengths fall within the standard green LED spectrum and produce visually identical green light output. The 2nm difference is imperceptible to the human eye and does not affect indicator functionality.

Q: Does the tinted lens on the SSF-LXH100LGD affect compatibility?

A: No. The tinted diffused lens is a manufacturing variation that does not impact electrical compatibility or mechanical fit. Both parts maintain the same optical diffusion characteristics required for circuit board indicator applications.

Q: Why is the viewing angle different between these parts?

A: The SSF-LXH100LGD provides a 60° viewing angle versus the 5505207F's 50° angle. This wider angle may offer improved visibility from off-axis positions but does not affect compatibility. Selection depends on specific application visibility requirements.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the 5505207F and SSF-LXH100LGD are ROHS3 compliant and REACH unaffected, meeting current environmental and safety regulations for electronic component use.
