3AC5V-F

Part Overview

The 3AC5V-F is an amber LED indication component manufactured by Bivar Inc., designed for discrete 5V radial through-hole applications. This part is classified as obsolete, necessitating the identification of alternative components to maintain design continuity and support ongoing production requirements. The part operates at 5V forward voltage with 8mA test current and delivers 40mcd brightness at a 20° viewing angle in a standard T-1 (3mm) package.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3AC5V-F is determined by strict adherence to the following electrical and mechanical parameters:

• Electrical Compatibility: Forward voltage of 5V is mandatory for direct circuit substitution without modification.
• Optical Properties: Amber color (peak wavelength 605–610nm range) maintains functional equivalence for indication purposes.
• Package Specifications: T-1 (3mm) through-hole radial configuration ensures mechanical fit in existing PCB designs.
• Brightness Consideration: Millicandela rating may vary within acceptable bounds for indication circuits; however, significant deviations should be evaluated against circuit requirements.
• Viewing Angle: Standard viewing angles (20°–60°) are typical for T-1 LEDs; wide-angle variants (60°+) provide enhanced visibility in some applications.

The SSL-LX305F4AD-5V qualifies as a substitute based on matching electrical voltage, amber color specification, T-1 package format, and through-hole mounting configuration.

Parameter Comparison

Engineering Selection Recommendations

The SSL-LX305F4AD-5V (Lumex Opto/Components Inc.) is an active product suitable for replacing the obsolete 3AC5V-F. Both components comply with ROHS3 and meet EAR99 export control classification. The substitute part maintains electrical compatibility at 5V forward voltage and T-1 (3mm) through-hole radial packaging.

Key differences include reduced brightness (10mcd versus 40mcd) and wider viewing angle (60° versus 20°), with diffused lens versus clear lens. These optical differences require evaluation against specific circuit application requirements to ensure adequate visibility and optical performance.

The SSL-LX305F4AD-5V is compliant with ROHS3 and REACH Unaffected regulations, supporting modern manufacturing and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can the SSL-LX305F4AD-5V directly replace the 3AC5V-F without circuit modification?

A: Both parts operate at 5V forward voltage and use T-1 (3mm) through-hole radial packages, allowing direct mechanical and electrical substitution. However, the SSL-LX305F4AD-5V delivers 10mcd brightness compared to the original 40mcd. Circuit designs relying on specific brightness levels must evaluate whether reduced luminous intensity is acceptable.

Q: What is the difference between "Clear" and "Diffused" lens transparency?

A: The 3AC5V-F features a clear lens providing concentrated light output with a 20° viewing angle. The SSL-LX305F4AD-5V uses a diffused amber lens that spreads light across a 60° viewing angle, resulting in lower peak brightness but wider visibility distribution. Selection depends on application-specific viewing angle requirements.

Q: Does the height difference (5.30mm vs. 5.00mm) affect mechanical compatibility?

A: The 0.30mm height difference is minor. Both parts conform to T-1 (3mm) standard dimensions and through-hole radial configuration. PCB layout and clearance should be verified if height-constrained designs are used.

Q: What are the compliance implications of the product status difference?

A: The 3AC5V-F is obsolete; the SSL-LX305F4AD-5V is active. Active status ensures ongoing availability and compliance with current manufacturing standards. The SSL-LX305F4AD-5V is ROHS3 compliant and REACH unaffected, supporting modern regulatory requirements.

Q: Are there inventory or supply chain advantages to the SSL-LX305F4AD-5V?

A: The SSL-LX305F4AD-5V has 1050 units in stock versus 917 for the 3AC5V-F. Active product status provides long-term supply availability, whereas the obsolete 3AC5V-F faces eventual stock depletion.
