Bivar 3AC5V-S Equivalent & Substitute Parts

Part Overview

The Bivar 3AC5V-S is a discrete 5V amber LED indicator with through-hole radial mounting and 3mm T-1 lens configuration. This component is currently obsolete, necessitating the identification of equivalent substitute parts that maintain functional compatibility in amber LED indication applications. Substitute parts must provide equivalent performance within the defined electrical and mechanical parameter ranges.

Substitute Part Grouping Explanation

The Lumex Opto/Components Inc. SSL-LX305F4AD-5V qualifies as a substitute based on the following matched parameters:

• Color Match: Both parts are amber indication LEDs
• Form Factor Match: Both utilize 3mm T-1 lens configuration with radial through-hole mounting
• Electrical Compatibility: Both operate at 5V forward voltage
• Package Match: Both use radial package configuration
• Environmental Rating Match: Both have MSL 1 (Unlimited) rating

Substitution is governed by the requirement that forward voltage, lens size, mounting type, and color remain constant. The substitute part varies in lens transparency (diffused versus clear), millicandela rating, and viewing angle, which are non-critical parameters that allow component interchangeability in functional amber indication circuits.

Parameter Comparison

Engineering Selection Recommendations

The Lumex SSL-LX305F4AD-5V is a functional substitute for the obsolete Bivar 3AC5V-S. The primary advantage of the SSL-LX305F4AD-5V is its active product status, ensuring continued availability and supply chain support. Both parts share identical forward voltage, lens size, and through-hole radial mounting configuration, supporting direct circuit compatibility.

The SSL-LX305F4AD-5V carries ROHS3 compliance and REACH Unaffected status, meeting modern regulatory requirements applicable to discrete semiconductor components. The MSL 1 rating on both parts indicates no moisture sensitivity constraints during storage and handling.

Design considerations include the reduced brightness of the substitute (10mcd versus 40mcd) and the diffused lens versus clear lens configuration. The wider 60° viewing angle of the substitute accommodates broader visibility requirements in some applications. The maximum height difference (5.00mm versus 6.10mm) is within typical PCB clearance tolerances for indicator LED applications.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable? A: Yes. Both parts operate at 5V forward voltage with identical lens size (3mm T-1), mounting type (through hole radial), and MSL rating (1, Unlimited). They function interchangeably in standard amber LED indication circuits.

Q: What is the difference in brightness between these parts? A: The Bivar 3AC5V-S provides 40mcd, while the Lumex SSL-LX305F4AD-5V provides 10mcd. The substitute delivers lower brightness due to its diffused lens design, which distributes light over a wider 60° viewing angle compared to the 30° angle of the original part.

Q: Can the SSL-LX305F4AD-5V be used in the same PCB layout? A: The parts are dimensionally compatible within normal PCB clearance tolerances. The substitute is 1.10mm shorter (5.00mm versus 6.10mm maximum height), which does not present clearance constraints in standard through-hole indicator applications.

Q: What is the wavelength difference between these parts? A: The Bivar 3AC5V-S has a peak wavelength of 605nm, while the Lumex substitute is rated at 610nm. This 5nm difference remains within the amber spectrum range and presents no functional distinction in indication applications.

Q: Why choose the Lumex substitute if the original part is brighter? A: The Lumex SSL-LX305F4AD-5V offers active product status with ongoing manufacturing, regulatory compliance (ROHS3, REACH Unaffected), and broader viewing angle. The diffused lens and lower brightness may be advantageous in applications where reduced glare or wider visibility is preferred.

Q: Are there storage or handling differences between these parts? A: Both parts carry MSL 1 (Unlimited) ratings, indicating identical moisture sensitivity and storage requirements. No special handling procedures differentiate these components.
