Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5UAC-1.5K is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Manufacturer: Bivar Inc.
• Color: Amber
• Lens Size: 5mm, T-1 3/4
• Mounting Type: Through Hole
• Package / Case: Radial
• Current - Test: 20mA

Allowable Parameter Variations: Substitute parts may differ in forward voltage (Vf), millicandela rating, lens transparency, viewing angle, and wavelength-peak within the amber LED spectrum, provided the mandatory criteria are maintained. These variations reflect different optical and electrical characteristics suitable for different circuit design requirements while maintaining mechanical and functional compatibility.

The 5AD substitute meets all mandatory compatibility criteria while offering an active product status and alternative optical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 5AD serves as a direct mechanical and electrical substitute for the obsolete 5UAC-1.5K. Both components share identical mounting characteristics, package configuration, and test current specifications. The 5AD is classified as an active product, ensuring ongoing availability and supply chain continuity.

Key differences in optical performance exist: the 5UAC-1.5K delivers 1500mcd with a 30° viewing angle and clear lens, while the 5AD delivers 25mcd with a 45° viewing angle and diffused lens. Forward voltage differs by 0.06V (1.94V versus 2V), which is within typical LED tolerance ranges for 20mA test current applications.

Selection between these components depends on circuit design requirements for luminous intensity, viewing angle, and lens diffusion characteristics. Both components maintain identical moisture sensitivity classification and export compliance ratings.

Frequently Asked Questions (FAQ)

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

A: Mechanical and electrical compatibility is confirmed. Both components are 5mm T-1 3/4 through-hole radial LEDs with identical test current (20mA) and mounting footprints. Forward voltage difference (0.06V) is within standard LED operating tolerances. Circuit designs must account for the 1475mcd difference in luminous intensity and the 15° difference in viewing angle.

Q: What is the primary reason for substitution?

A: The 5UAC-1.5K is classified as obsolete. The 5AD is an active product from the same manufacturer with identical mechanical and package specifications, ensuring component availability for new designs and ongoing production support.

Q: How do lens transparency differences affect application suitability?

A: The 5UAC-1.5K features a clear lens, providing direct light transmission with concentrated intensity. The 5AD features a diffused lens, which scatters light across a wider viewing angle (45° versus 30°). Application requirements for light distribution and intensity determine which lens type is appropriate.

Q: Are there compliance or certification differences between these components?

A: Both components share identical moisture sensitivity classification (MSL 1 - Unlimited), ECCN rating (EAR99), and HTSUS classification (8541.41.0000). No compliance or certification differences exist.

Q: What is the wavelength difference between these components?

A: Peak wavelength differs by 3nm (608nm for 5UAC-1.5K versus 605nm for 5AD). Both wavelengths fall within the amber LED spectrum and are visually indistinguishable in typical indication applications.
