Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5370T5LC is determined by the following critical parameters:

Color Match: Green wavelength output (target range 560-570nm) ensures visual consistency in circuit board indicator applications.

Configuration: Single LED configuration maintains functional equivalence for single-indicator circuit designs.

Mounting Type: Through-hole mounting preserves PCB assembly compatibility with existing board layouts and soldering processes.

Lens Characteristics: Diffused, tinted lens type with domed top provides equivalent light distribution and appearance in indicator applications.

Electrical Compatibility: Operating voltage and current ratings must support integration into existing circuit designs without requiring redesign of current-limiting resistor networks.

Compliance Standards: ROHS3 compliance and REACH unaffected status ensure regulatory alignment with modern manufacturing and environmental requirements.

The Dialight 5505204F meets these substitution criteria while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The 5370T5LC is classified as obsolete, while the 5505204F is active. Active product status ensures ongoing manufacturer support, availability, and compliance with current regulatory standards.

Compliance Alignment: Both components maintain ROHS3 compliance and REACH unaffected status, supporting integration into modern manufacturing environments without regulatory barriers.

Functional Equivalence: Both components share green color output, single configuration, diffused tinted lens with domed top, and through-hole mounting. These shared characteristics establish functional equivalence for circuit board indicator applications.

Electrical Parameter Differences: The 5505204F operates at higher voltage (2.2V vs 1.8V) and current (20mA vs 2mA) ratings with correspondingly higher brightness output (34mcd vs 1.2mcd). Circuit designs must accommodate these electrical differences through appropriate resistor network adjustment.

Physical Form Factor: The 5505204F features a larger 5mm lens diameter compared to the 2.00mm diameter of the 5370T5LC. PCB layout modifications may be required to accommodate the larger component footprint.

Frequently Asked Questions (FAQ)

Q: Can the 5505204F directly replace the 5370T5LC without circuit modification?

A: Direct replacement without modification is not recommended. The 5505204F requires higher operating voltage (2.2V vs 1.8V) and current (20mA vs 2mA). Current-limiting resistor values must be recalculated to prevent component damage and ensure proper brightness output.

Q: Are there physical compatibility issues between these components?

A: Yes. The 5505204F has a 5mm lens diameter (T-1 3/4 package) compared to the 2.00mm diameter of the 5370T5LC. PCB hole spacing and component mounting clearances must be verified before substitution. Panel cutout dimensions may require modification.

Q: Why is the 5505204F brighter than the 5370T5LC?

A: The 5505204F operates at higher current (20mA vs 2mA) and voltage (2.2V vs 1.8V), resulting in increased light output (34mcd vs 1.2mcd). This brightness difference is a direct consequence of the higher electrical operating parameters.

Q: Do both components meet current environmental regulations?

A: Yes. Both the 5370T5LC and 5505204F are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the wavelength difference between these components?

A: The wavelength difference is minimal (565nm vs 563nm), representing a 2nm variation within the green spectrum. This difference is imperceptible in visual indicator applications and does not affect functional equivalence.

Q: Is the 5505204F suitable for low-power circuit designs?

A: The 5505204F minimum current rating of 20mA may exceed requirements for ultra-low-power applications. The higher current demand increases power consumption compared to the 2mA 5370T5LC. Circuit power budget analysis is required before substitution.

Q: What is the viewing angle specification for the 5370T5LC?

A: The viewing angle for the 5370T5LC is not specified in the provided technical parameters. The 5505204F specifies a 50° viewing angle. Actual viewing angle performance should be evaluated through application testing if this parameter is critical to the design.
