Substitute Part Grouping Explanation

Substitution of the 5UYC-F with the INL-5AY30 is based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is determined by the following matched specifications:

Electrical Parameters: Both components operate at 2V forward voltage with 20mA test current, ensuring direct circuit compatibility without modification to current-limiting resistor networks or power supply configurations.

Optical Parameters: Both components emit yellow light at 590nm peak wavelength with 1000mcd brightness rating and 30° viewing angle, maintaining identical visual indication performance in end-use applications.

Mechanical Parameters: Both components feature 5mm T-1 3/4 clear lens with round domed top configuration and radial through-hole mounting, ensuring identical PCB footprint compatibility and mechanical fit within existing enclosures.

Environmental Parameters: Both components carry MSL 1 (Unlimited) moisture sensitivity rating, confirming equivalent environmental robustness.

The INL-5AY30 is classified as active product status, providing continued availability and supply chain reliability compared to the obsolete 5UYC-F.

Frequently Asked Questions (FAQ)

Q: Can the INL-5AY30 be used as a direct replacement for the 5UYC-F in existing designs?

A: Yes. The INL-5AY30 is a direct parametric equivalent with identical electrical specifications (2V forward voltage, 20mA test current), optical specifications (1000mcd, 590nm wavelength, 30° viewing angle), and mechanical specifications (5mm T-1 3/4 through-hole radial package). No circuit modifications or PCB redesign are required.

Q: What is the significance of the wavelength difference between 590nm and 592nm?

A: The 2nm difference between the 5UYC-F peak wavelength (590nm) and INL-5AY30 peak wavelength (592nm) is within normal manufacturing tolerance for yellow LEDs and produces no perceptible difference in color appearance or indication function. Both components are specified for yellow light emission in the 590nm range.

Q: Are there any height differences that affect mechanical fit?

A: The maximum height difference is 0.05mm (5UYC-F: 8.60mm vs. INL-5AY30: 8.65mm). This difference is negligible for through-hole mounting applications and does not affect PCB clearance, enclosure fit, or mechanical assembly.

Q: Why is the INL-5AY30 preferred over the 5UYC-F?

A: The INL-5AY30 is classified as active product status with substantial inventory availability (10717 pcs), whereas the 5UYC-F is obsolete. For new production and long-term maintenance applications, the active status of the INL-5AY30 ensures continued supply chain access and eliminates obsolescence risk.

Q: What compliance certifications apply to the INL-5AY30?

A: The INL-5AY30 carries RoHS3 compliance and REACH unaffected status. Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications for export and trade purposes.

Q: Is the radial package configuration identical between both components?

A: Yes. Both the 5UYC-F and INL-5AY30 use radial through-hole package configuration with identical lead spacing and mounting orientation, ensuring direct PCB footprint compatibility.
