LED CBI 5MM Yellow Through Hole 5340H7LC Equivalent & Substitute Parts

Part Overview

The VCC 5340H7LC is a 5mm yellow circuit board indicator LED with through-hole mounting. This component is classified as obsolete, necessitating identification of active substitute parts for ongoing production and maintenance applications. The 5340H7LC features a diffused, tinted lens with a domed top configuration, designed for standard through-hole PCB assembly. Due to its obsolete status, equivalent active parts must be evaluated to maintain design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5340H7LC is based on the following critical parameters that define functional and mechanical compatibility:

Primary Compatibility Criteria:

• Color: Yellow (585nm peak wavelength)
• Lens Size: 5mm, T-1 3/4
• Lens Style: Round with Domed Top
• Mounting Type: Through Hole
• Configuration: Single LED
• RoHS3 Compliance
• MSL Rating: 1 (Unlimited)

Secondary Electrical Parameters:

• Voltage Rating: 1.9V to 2.1V range
• Current Rating: 2mA to 10mA range
• Millicandela Rating: 2.1mcd to 6.3mcd range

The Dialight 5502304F meets all primary compatibility criteria and operates within acceptable electrical parameter ranges for circuit board indicator applications. The substitute part maintains identical mechanical form factor, lens configuration, and mounting interface while providing enhanced brightness and current capacity.

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5502304F is an active substitute for the obsolete VCC 5340H7LC. Both components maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard PCB assembly processes and environmental requirements.

The 5502304F provides increased brightness (6.3mcd versus 2.1mcd) and higher current capacity (10mA versus 2mA) while maintaining identical mechanical form factor and through-hole mounting interface. The voltage rating differential (2.1V versus 1.9V) falls within acceptable tolerance for circuit board indicator applications.

The substitute part is currently in active production status with established supply chain availability, eliminating obsolescence risk associated with the original 5340H7LC component.

Frequently Asked Questions (FAQ)

Q: Can the Dialight 5502304F directly replace the VCC 5340H7LC in existing designs?

A: The 5502304F is mechanically and functionally compatible as a direct substitute. Both components share identical 5mm T-1 3/4 through-hole form factor, round domed lens style, and yellow color specification. Circuit designs must accommodate the higher voltage rating (2.1V versus 1.9V) and increased current capacity (10mA versus 2mA).

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete versus active), brightness output (2.1mcd versus 6.3mcd), current rating (2mA versus 10mA), and voltage rating (1.9V versus 2.1V). The 5502304F also specifies a 50° viewing angle, whereas the original part does not provide this parameter.

Q: Are both parts RoHS compliant?

A: Both the 5340H7LC and 5502304F are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings, meeting current environmental and assembly standards.

Q: What is the impact of the increased brightness rating on circuit design?

A: The 5502304F provides 3x greater brightness output. Existing current-limiting resistor values in the circuit may require adjustment to maintain desired indicator brightness levels and prevent excessive LED current draw.

Q: Is the lens type difference significant?

A: The original part specifies diffused, tinted lens while the substitute specifies diffused lens only. Both maintain the same round domed top configuration and 5mm size. The tint difference may result in slight color appearance variation under identical operating conditions.
