Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5680F7_1 is based on the following critical parameters that must align between the main part and substitute components:

Functional Equivalence Criteria:

• Dual-level configuration (2 High) with red and yellow LED elements
• Diffused, tinted lens type with round domed top geometry
• Through-hole, right-angle mounting orientation
• Voltage ratings: 2V Red, 2.1V Yellow
• Wavelength specifications: 635nm (Red), 583nm (Yellow)
• RoHS3 compliance and REACH unaffected status

Allowable Variations:

• Lens diameter (3mm to 5mm acceptable for circuit board layout adaptation)
• Current rating (30mA to 20mA acceptable with design verification)
• Millicandela output (brightness variation within indicator application tolerance)
• Viewing angle (when not specified in original, substitute specification acceptable)
• Product status transition (Obsolete to Active acceptable for procurement)

The substitute part 5520113F from Dialight meets these criteria with documented compatibility in dual-level indicator applications.

Engineering Selection Recommendations

Primary Substitute: 5520113F (Dialight)

The 5520113F qualifies as a functional substitute based on the following engineering criteria:

Compliance Alignment:

• Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in manufacturing and supply chain operations.

Functional Compatibility:

• Dual-level red/yellow configuration with identical voltage ratings (2V Red, 2.1V Yellow) ensures direct functional replacement in indicator circuits.
• Diffused, tinted lens with round domed top maintains optical characteristics for circuit board indicator applications.
• Through-hole, right-angle mounting preserves PCB assembly compatibility.

Design Considerations:

• Lens diameter increase from 3mm to 5mm requires PCB footprint verification; hole spacing and mounting pad dimensions must accommodate the larger component body.
• Current rating reduction from 30mA to 20mA necessitates circuit design review to confirm series resistor values and power supply specifications remain within acceptable operating parameters.
• Wavelength specifications remain within acceptable tolerance for dual-color indicator applications (Yellow: 583nm to 585nm).

Product Status:

• Transition from obsolete (5680F7_1) to active production status (5520113F) ensures long-term procurement availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the 5520113F directly replace the 5680F7_1 without PCB modifications?

A: The 5520113F is functionally equivalent but requires PCB footprint verification. The lens diameter increases from 3mm to 5mm, necessitating confirmation that mounting holes and pad spacing accommodate the larger component. Mounting orientation and through-hole depth remain compatible.

Q: What is the impact of the 20mA current rating on the 5520113F compared to the 30mA rating of the 5680F7_1?

A: The lower current rating requires circuit design review. Series resistor values and power supply specifications must be verified to ensure the circuit operates within the 20mA maximum rating. This typically involves recalculating resistor values based on the target LED forward voltage and available supply voltage.

Q: Are the color wavelengths compatible between the two parts?

A: Yes. Red wavelengths are identical at 635nm. Yellow wavelengths differ by 2nm (583nm vs. 585nm), which is within acceptable tolerance for visual indicator applications and does not affect functional performance.

Q: Does the 5520113F provide adequate brightness for the intended application?

A: The 5520113F delivers 12.3mcd brightness compared to the 5680F7_1 specifications of 10mcd Red and 6.3mcd Yellow. The increased brightness is acceptable for circuit board indicator applications and does not introduce compatibility issues.

Q: Are there any compliance or regulatory differences between the two parts?

A: No. Both components maintain identical RoHS3 compliance, REACH unaffected status, MSL rating of 1 (Unlimited), and ECCN/HTSUS classifications. Regulatory and environmental compliance requirements are fully aligned.

Q: What is the significance of the product status change from Obsolete to Active?

A: The 5520113F is actively manufactured by Dialight, ensuring reliable long-term procurement availability. The 5680F7_1 obsolete status indicates discontinued production, making the 5520113F the appropriate substitute for ongoing design support and component sourcing.

Q: Can the 5520113F be used in existing designs without circuit redesign?

A: Functional substitution is possible with design verification. PCB footprint accommodation for the larger 5mm lens diameter and circuit design review for the 20mA current rating are required. Electrical performance and compliance characteristics remain compatible.
