Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 5694S3 is based on the following critical parameters that must align between the main part and substitute components:

Primary Substitution Criteria:

• Configuration: 4-high LED assembly
• Mounting Type: Through-hole, right-angle orientation
• Voltage Rating: 2.2V nominal operation
• Regulatory Compliance: ROHS3 compliant, EAR99 classification
• Moisture Sensitivity: MSL 1 (Unlimited)

Secondary Compatibility Parameters:

• Current Rating: 25mA (main part) to 20mA (substitute acceptable within circuit design tolerance)
• Wavelength: 602nm amber (main part) to 600nm orange (substitute within visible spectrum amber-orange range)
• Millicandela Rating: 6.5mcd (main part) to 7mcd (substitute provides equivalent or superior brightness)
• Lens Configuration: Oval with flat top (main part) to round with domed top (substitute) - both provide adequate light distribution for circuit board indication

The substitute part 5680107777F from Dialight meets these criteria while maintaining active product status and full regulatory compliance.

Engineering Selection Recommendations

Primary Recommendation: Dialight 5680107777F

The Dialight 5680107777F qualifies as a direct functional substitute for the obsolete VCC 5694S3 based on the following engineering criteria:

1. Regulatory Compliance: Both components maintain ROHS3 compliance and EAR99 export classification, ensuring no change to supply chain or regulatory documentation requirements.

2. Electrical Compatibility: Identical 2.2V voltage rating and 4-high configuration enable direct circuit integration. The 5mA current reduction (25mA to 20mA) is accommodated within standard circuit board indicator design practices where current-limiting resistors are typically employed.

3. Optical Performance: The 600nm wavelength (substitute) versus 602nm (original) represents a 2nm variance within the amber-orange visible spectrum. The 7mcd brightness rating of the substitute exceeds the original 6.5mcd specification, providing equivalent or superior visual indication performance.

4. Mechanical Compatibility: Both components feature through-hole, right-angle mounting. The substitute's 3mm T-1 form factor and domed lens geometry differ from the original oval flat-top design but maintain functional equivalence for circuit board indication applications.

5. Product Lifecycle: The substitute maintains active product status with confirmed inventory availability (722 pcs), ensuring long-term supply continuity compared to the obsolete original part.

6. Packaging and Handling: Both components share MSL 1 (Unlimited) moisture sensitivity classification, requiring no change to storage or handling procedures.

Frequently Asked Questions (FAQ)

Q: Can the Dialight 5680107777F directly replace the VCC 5694S3 without circuit modification?

A: The substitute part is electrically and mechanically compatible for direct board-level replacement. The 5mA current reduction (25mA to 20mA) is accommodated by existing current-limiting circuit design in standard LED indicator applications. No circuit redesign is required.

Q: What is the significance of the wavelength difference (602nm vs. 600nm)?

A: The 2nm variance falls within the amber-orange visible spectrum range and produces no perceptible difference in human visual perception. Both wavelengths are classified as amber-orange indicator colors and are functionally equivalent for circuit board indication purposes.

Q: Does the lens geometry change (oval flat-top vs. round domed-top) affect performance?

A: The lens geometries differ but both provide adequate light distribution for circuit board indicator applications. The substitute's diffused, domed lens may provide slightly wider viewing angle characteristics compared to the original oval flat-top design. Optical performance remains suitable for standard indication applications.

Q: Are there any compliance or certification changes?

A: Both components maintain identical ROHS3 compliance, EAR99 export classification, and MSL 1 moisture sensitivity rating. No changes to regulatory documentation, supply chain procedures, or handling requirements are necessary.

Q: What is the inventory status of the substitute part?

A: The Dialight 5680107777F maintains active product status with 722 pcs confirmed in stock. The original VCC 5694S3 is obsolete with 1074 pcs remaining inventory. The substitute ensures long-term supply continuity.

Q: Is the brightness difference (6.5mcd vs. 7mcd) significant?

A: The 0.5mcd increase in the substitute represents approximately 7.7% higher brightness. This improvement maintains or exceeds the original visual indication performance and poses no compatibility concerns.

Q: Can the substitute be used in new designs?

A: Yes. The Dialight 5680107777F is recommended for both replacement applications (obsolete part substitution) and new circuit board indicator designs requiring 4-high LED assemblies with 2.2V operation and through-hole right-angle mounting.
