Bivar Inc. 3AC - Amber LED T-1 Equivalent & Substitute Parts

Part Overview

The Bivar Inc. 3AC is an amber LED indicator designed for through-hole mounting in a 3mm T-1 package. This discrete component provides amber light indication at 40mcd with a 2V forward voltage and 30° viewing angle. The part is currently obsolete, making identification of suitable substitute components essential for design updates, system modifications, and manufacturing continuity. Substitute parts must maintain compatibility with the original electrical specifications and through-hole mounting configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Bivar Inc. 3AC must meet the following critical parameters for functional compatibility:

Primary compatibility criteria:

• Color: Amber
• Lens Size: 3mm, T-1
• Mounting Type: Through Hole
• Package / Case: Radial
• Voltage - Forward (Vf): 2V nominal range (2.0V to 2.1V acceptable)
• Current - Test: 20mA
• Lens Transparency: Clear

Secondary parameters affecting application suitability:

• Millicandela Rating: Range 40-400mcd (determines brightness compatibility)
• Viewing Angle: 30-45° (optical distribution characteristic)
• Wavelength - Peak: 592-605nm (amber spectrum range)
• Height (Max): 4.50-5.73mm (mechanical clearance consideration)

The substitute parts listed maintain core electrical and mechanical compatibility while offering alternative brightness levels and optical characteristics within acceptable operational parameters.

Engineering Selection Recommendations

Broadcom Limited HLMP-Y701-G0000 is the preferred substitute for applications requiring enhanced brightness. This part maintains identical forward voltage (2V) and test current (20mA) specifications, with 10x increased brightness (400mcd vs. 40mcd). The expanded 45° viewing angle provides broader optical distribution. Active product status ensures supply availability and long-term production continuity. RoHS3 Compliant and REACH Unaffected certifications confirm regulatory alignment.

Lumex Opto/Components Inc. SSL-LX3044AC is the optimal direct replacement for optical and mechanical equivalence. This part provides a 2x brightness increase (80mcd vs. 40mcd) with maintained 30° viewing angle and identical wavelength peak (605nm). Forward voltage differential of 0.1V (2.1V vs. 2V) remains within standard operational tolerance for amber LED applications. Active product status and RoHS3 Compliant certification ensure continued availability and regulatory compliance.

Both substitute options are active products with established supply chains, providing immediate sourcing alternatives to the obsolete Bivar Inc. 3AC component.

Frequently Asked Questions (FAQ)

Q: Can the HLMP-Y701-G0000 and SSL-LX3044AC be used interchangeably with the 3AC?

A: Both are mechanically and electrically compatible as through-hole mounted 3mm T-1 amber LEDs operating at 2V/2.1V and 20mA. The primary difference is brightness: HLMP-Y701-G0000 provides 400mcd, SSL-LX3044AC provides 80mcd, and the original 3AC provides 40mcd. Optical compatibility depends on application brightness requirements and viewing angle specifications.

Q: How do the forward voltage differences affect circuit design?

A: The Bivar 3AC and Broadcom HLMP-Y701-G0000 operate at 2V, while the Lumex SSL-LX3044AC operates at 2.1V. This 0.1V differential is within the tolerance range for standard amber LED indicator circuits and does not require circuit modification for typical applications.

Q: Are there height clearance considerations when substituting?

A: The original Bivar 3AC has a maximum height of 4.50mm. Both substitute parts are taller: HLMP-Y701-G0000 at 5.20mm and SSL-LX3044AC at 5.73mm. PCB layout and mechanical enclosure clearance must be verified to accommodate the increased height.

Q: What is the difference between viewing angles of 30° and 45°?

A: Viewing angle defines the cone of light distribution from the LED. The original 3AC and SSL-LX3044AC have 30° viewing angles (narrower, more directional light). The HLMP-Y701-G0000 has a 45° viewing angle (wider, more dispersed light). Application-specific viewing requirements determine the appropriate selection.

Q: Are both substitute parts RoHS compliant?

A: Both the Broadcom HLMP-Y701-G0000 and Lumex SSL-LX3044AC are RoHS3 Compliant with REACH Unaffected status, meeting modern environmental and safety regulations for electronic components.
