Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 5UAC-1.5K-F is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Color: Amber
• Lens Size: 5mm, T-1 3/4
• Mounting Type: Through Hole
• Package / Case: Radial
• Height (Max): 8.60mm

Electrical Parameters (Allowable Variance):

• Voltage - Forward (Vf): 1.9V to 2.0V range
• Current - Test: 20mA to 30mA range
• Millicandela Rating: Brightness levels suitable for indication applications
• Wavelength - Peak: 605nm to 608nm range (amber spectrum)

Optical Parameters (Allowable Variance):

• Viewing Angle: 30° to 40° range
• Lens Transparency: Clear or Diffused (both suitable for amber indication)

The substitute part 5AD-F meets these criteria within allowable tolerances for through-hole amber LED indicator applications.

Parameter Comparison

Engineering Selection Recommendations

The 5AD-F serves as a functional substitute for the obsolete 5UAC-1.5K-F based on the following engineering criteria:

Mechanical Compatibility: Both components share identical physical dimensions (5mm T-1 3/4 lens, 8.60mm maximum height) and radial through-hole package configuration, ensuring direct PCB mounting compatibility without layout modifications.

Electrical Compatibility: The 5AD-F operates within acceptable voltage and current parameters (2.0V forward voltage versus 1.9V, 20mA test current versus 30mA). Circuit designs accommodating the original 1.9V/30mA specification will function with the 5AD-F within standard LED indicator application tolerances.

Optical Characteristics: While the 5AD-F features a diffused lens (versus the clear lens of the 5UAC-1.5K-F) and lower brightness rating (25mcd versus 1500mcd), both components emit amber light within the 605nm to 608nm wavelength range. The diffused lens provides a wider 40° viewing angle compared to the 30° angle of the original part.

Compliance and Availability: The 5AD-F is classified as active product status with RoHS3 compliance certification. Current inventory of 680 pieces ensures supply continuity for production and replacement applications.

Product Status Consideration: Substitution is necessary due to the obsolete classification of the 5UAC-1.5K-F. The 5AD-F represents the current-generation equivalent from the same manufacturer.

Frequently Asked Questions (FAQ)

Q: Can the 5AD-F directly replace the 5UAC-1.5K-F in existing circuit designs?

A: Yes, the 5AD-F is mechanically and electrically compatible for through-hole mounting applications. The forward voltage difference (2.0V versus 1.9V) and current difference (20mA versus 30mA) fall within standard LED indicator circuit tolerances. Circuit designs should be verified for brightness requirements, as the 5AD-F has a lower millicandela rating.

Q: What is the primary difference between the clear lens of the 5UAC-1.5K-F and the diffused lens of the 5AD-F?

A: The 5UAC-1.5K-F features a clear lens with 1500mcd brightness and 30° viewing angle, providing concentrated light output. The 5AD-F features a diffused lens with 25mcd brightness and 40° viewing angle, distributing light over a wider area. Selection depends on application requirements for brightness concentration versus viewing angle distribution.

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

A: Yes. Both components are 5mm T-1 3/4 through-hole radial packages with identical maximum height of 8.60mm. No PCB layout modifications are required for substitution.

Q: What is the wavelength difference between these components?

A: The 5UAC-1.5K-F has a peak wavelength of 608nm, while the 5AD-F has a peak wavelength of 605nm. Both wavelengths fall within the amber spectrum and are visually indistinguishable for indicator applications.

Q: Does the 5AD-F meet RoHS compliance requirements?

A: Yes, the 5AD-F is RoHS3 compliant. Both components have MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.

Q: Why is the 5UAC-1.5K-F classified as obsolete?

A: The 5UAC-1.5K-F is no longer in active production. The 5AD-F represents the current-generation amber LED indicator from Bivar Inc. for equivalent through-hole applications.
