Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 5324F7 is based on the following critical parameters that must align between the main part and substitute candidates:

Primary Substitution Criteria:

• Color: Yellow (x 4) configuration
• Wavelength - Peak: 585nm
• Configuration: 4 Wide
• Voltage Rating: 2.1V
• Millicandela Rating: 6.3mcd
• Mounting Type: Through Hole
• RoHS3 Compliance
• MSL Rating: 1 (Unlimited)

The Dialight 5510307004F meets these core electrical and optical parameters. Variations in current rating (10mA vs. 30mA), lens type (diffused vs. clear tinted), and mounting orientation (right angle vs. straight) represent design trade-offs that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5510307004F qualifies as a functional substitute for the obsolete VCC 5324F7 based on matching electrical specifications, optical wavelength, configuration, and regulatory compliance. Both parts maintain ROHS3 compliance and identical MSL ratings, supporting equivalent environmental and reliability profiles.

Key Considerations for Selection:

Current rating differential: The substitute operates at 10mA versus the original 30mA specification. Circuit designs must accommodate this reduced current draw, which may require resistor value adjustments in series-limiting configurations.

Lens optical characteristics: The diffused lens type of the substitute differs from the clear tinted lens of the original. This affects light distribution patterns and may impact visual appearance in the end application.

Mounting orientation: The right angle mounting option of the substitute provides design flexibility for applications requiring perpendicular PCB orientation, though straight through hole mounting remains available.

Active product status: The Dialight part maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete VCC component.

Frequently Asked Questions (FAQ)

Q: Can the Dialight 5510307004F directly replace the VCC 5324F7 without circuit modification?

A: Direct replacement is possible only if the application circuit accommodates the 10mA current specification. Circuits designed for 30mA operation require resistor recalculation to maintain proper LED brightness and current limiting.

Q: What is the impact of the diffused lens on visual performance?

A: The diffused lens of the Dialight part provides wider light scattering compared to the clear tinted lens of the original. This results in broader viewing angles and softer light distribution, suitable for applications where uniform illumination is preferred over concentrated brightness.

Q: Are both parts suitable for the same PCB layout?

A: Both parts feature through hole mounting and identical electrical specifications. The Dialight part offers right angle mounting as an additional option, providing layout flexibility. Standard straight mounting configurations are compatible with existing PCB designs.

Q: What compliance certifications apply to both parts?

A: Both the VCC 5324F7 and Dialight 5510307004F maintain ROHS3 compliance, MSL Level 1 (unlimited moisture sensitivity), and EAR99 export classification. Both fall under HTSUS code 8541.41.0000.

Q: Why is the VCC 5324F7 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The Dialight 5510307004F represents an active alternative that meets the core functional requirements while maintaining current manufacturing support and supply availability.
