Bivar Inc. 5AT-F LED Amber Clear 5MM T/H Equivalent & Substitute Parts

Part Overview

The Bivar Inc. 5AT-F is a through-hole amber LED indicator with a clear lens, designed for discrete 2V radial applications. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and procurement continuity. The 5AT-F delivers 40 millicandela output with a 35-degree viewing angle and operates at 2V forward voltage with 20mA test current. Due to its obsolete status, sourcing alternatives that maintain electrical and mechanical compatibility is critical for production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5AT-F are identified based on strict electrical and mechanical compatibility criteria. The following parameters define acceptable substitution:

Core Compatibility Parameters:

• Amber color specification
• 5mm T-1 3/4 lens size
• Through-hole radial mounting configuration
• 2V forward voltage (Typ)
• 20mA test current
• 605nm peak wavelength
• 8.60mm maximum height
• Radial package type

The primary distinction among substitute candidates is lens transparency (clear versus diffused) and resulting millicandela output. Lens transparency affects light distribution characteristics and brightness intensity but does not alter electrical operating parameters or physical mounting compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Bivar Inc. 5AD-F serves as a direct electrical and mechanical substitute for the obsolete 5AT-F. Both components share identical forward voltage, test current, peak wavelength, lens size, mounting configuration, and physical dimensions. The 5AD-F is currently in active production status with RoHS3 compliance certification, ensuring long-term availability and regulatory alignment.

The primary technical distinction is lens transparency: the 5AT-F features a clear lens delivering 40mcd at 35 degrees, while the 5AD-F features a diffused lens delivering 25mcd at 40 degrees. This difference reflects optical design rather than electrical incompatibility. Selection between these variants depends on application-specific requirements for brightness intensity and light distribution pattern.

The 5AD-F is recommended for applications where the 5AT-F is no longer available, provided that the diffused lens optical characteristics and reduced millicandela output are acceptable for the intended indication function.

Frequently Asked Questions (FAQ)

Q: Can the 5AD-F directly replace the 5AT-F in existing circuit designs?

A: Yes, from an electrical and mechanical standpoint. Both components operate at 2V forward voltage with 20mA test current and use identical through-hole radial mounting. Physical dimensions and package configuration are identical. The primary consideration is optical performance: the 5AD-F diffused lens produces 25mcd versus the 5AT-F clear lens at 40mcd, with a slightly wider viewing angle (40° versus 35°).

Q: What is the difference between clear and diffused lens transparency?

A: Clear lenses concentrate light output in a narrower beam with higher peak brightness (40mcd). Diffused lenses scatter light across a wider viewing angle (40°) with lower peak brightness (25mcd). Clear lenses provide directional indication; diffused lenses provide broader visibility with reduced intensity.

Q: Are there any compliance or certification differences?

A: The 5AD-F carries RoHS3 compliance certification and is in active production. The 5AT-F is obsolete. Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Q: Does the 5AD-F fit the same PCB footprint as the 5AT-F?

A: Yes. Both components are 5mm T-1 3/4 through-hole radial packages with 8.60mm maximum height. PCB hole spacing and lead configuration are identical.

Q: What is the moisture sensitivity level for these components?

A: Both the 5AT-F and 5AD-F carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
