Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5340H5LC is determined by the following critical parameters that must align across components:

Mandatory Compatibility Parameters:

• Color: Green
• Configuration: Single
• Mounting Type: Through Hole
• Wavelength Range: Peak wavelength within visible green spectrum (560-565nm acceptable)
• Lens Type: Diffused construction
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Current Rating: May increase from 2mA to higher values (10mA acceptable for circuit board indicator applications)
• Voltage Rating: May increase from 1.8V to 2.1V (forward voltage variation within LED specifications)
• Millicandela Rating: May increase from 2.3mcd to 10mcd (brightness increase acceptable for indicator function)
• Viewing Angle: Addition of specified viewing angle (65°) acceptable
• Lens Style: Variation in physical lens description acceptable if optical function maintained

The substitute part 5502204F meets all mandatory compatibility parameters while operating at higher current and voltage ratings, which is acceptable for through-hole LED circuit board indicator applications.

Parameter Comparison

Engineering Selection Recommendations

The 5502204F from Dialight is a direct functional substitute for the obsolete 5340H5LC. Selection of this substitute is supported by the following engineering factors:

Compliance and Regulatory Alignment: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications subject to environmental directives.

Product Status: The 5340H5LC is obsolete, making the 5502204F the appropriate active alternative for new designs and ongoing production requirements.

Electrical Compatibility: The 5502204F operates at higher current (10mA versus 2mA) and voltage (2.1V versus 1.8V) ratings. These parameters are acceptable for through-hole LED circuit board indicator applications where the substitute component provides increased brightness (10mcd versus 2.3mcd) while maintaining the same green wavelength specification (563nm versus 562nm).

Mechanical and Optical Compatibility: Both components feature diffused lens construction and through-hole mounting, ensuring mechanical fit and optical performance consistency in circuit board applications.

Moisture Sensitivity: Both components carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints during storage, handling, or assembly.

Frequently Asked Questions (FAQ)

Q: Can the 5502204F directly replace the 5340H5LC in existing circuit board designs?

A: The 5502204F is mechanically and electrically compatible for through-hole mounting applications. However, circuit designs must accommodate the higher forward voltage (2.1V versus 1.8V) and current rating (10mA versus 2mA). Current-limiting resistor values in the circuit may require adjustment to maintain proper LED operation.

Q: What is the primary reason for substitution?

A: The 5340H5LC is classified as obsolete. The 5502204F is an active product from Dialight that maintains functional equivalence for green LED circuit board indicator applications.

Q: Are there differences in lens appearance between these components?

A: The 5340H5LC features a diffused, tinted lens with round domed top in 5mm T-1 3/4 size. The 5502204F features a diffused lens with specified 65° viewing angle. Both provide diffused optical characteristics suitable for circuit board indicator functions.

Q: Do both components meet the same regulatory requirements?

A: Yes. Both the 5340H5LC and 5502204F are ROHS3 compliant and REACH unaffected, maintaining equivalent regulatory status for applications subject to environmental directives.

Q: What is the brightness difference between these components?

A: The 5502204F provides 10mcd brightness compared to 2.3mcd for the 5340H5LC. This increased brightness is a result of the higher current rating and does not affect functional compatibility in circuit board indicator applications.

Q: Are there packaging differences?

A: The 5340H5LC is specified with dash packaging notation. The 5502204F is supplied in bulk packaging. Both are through-hole components suitable for standard PCB assembly processes.

Q: Can the 5502204F be used in low-power applications requiring 2mA operation?

A: The 5502204F is rated for 10mA operation. In applications requiring lower current, circuit design must include appropriate current-limiting resistors to operate the component within acceptable parameters.
