Bivar 5SGD LED GREEN DIFFUSED T-1 3/4 Through Hole

Part Overview

The Bivar 5SGD is a green diffused T-1 3/4 through-hole LED indicator designed for discrete 2.1V radial applications. This component is designated as obsolete and no longer in active production. Identifying compatible substitute parts is essential for system redesign, legacy system maintenance, and continued supply chain availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the Bivar 5SGD is established based on the following critical parameters:

• Color: Green (must match for consistent visual indication)
• Lens Transparency: Diffused (affects light distribution characteristics)
• Lens Size and Package: 5mm T-1 3/4 Through Hole Radial (mechanical and pin compatibility)
• Voltage - Forward (Vf): 2.1V (electrical operating requirement)
• Current - Test: 20mA (circuit design specification)
• Viewing Angle: 45° (optical performance specification)
• Lens Style: Round with Domed Top (form factor requirement)

The Bivar 5GD meets these critical parameters and is classified as a direct substitute. The primary difference is the millicandela rating variation (5SGD: 30mcd vs. 5GD: 25mcd), which reflects acceptable brightness variation within the same product line. The 5GD is active in production status with ROHS3 compliance, making it the recommended current-generation equivalent.

Parameter Comparison

Engineering Selection Recommendations

The Bivar 5GD is the direct substitute for the obsolete Bivar 5SGD. Both components share identical core electrical and mechanical specifications, ensuring pin-compatible and functional equivalence in through-hole PCB applications.

The 5GD offers the additional advantage of active product status with ROHS3 compliance, providing assurance of ongoing manufacturing support and regulatory alignment. The 5-millicandela reduction in brightness output (5SGD at 30mcd versus 5GD at 25mcd) remains within acceptable variance for LED indicator applications and does not alter the fundamental operating characteristics required for green status indication circuits.

Selection of the Bivar 5GD eliminates obsolescence risk while maintaining mechanical, electrical, and optical performance compatibility with designs originally specified for the 5SGD.

Frequently Asked Questions (FAQ)

Q: What are the key differences between the Bivar 5SGD and 5GD? A: The components are functionally equivalent. The primary difference is product status (5SGD is obsolete; 5GD is active) and a 5-millicandela difference in brightness (5SGD: 30mcd; 5GD: 25mcd). Electrical specifications, physical dimensions, and lens characteristics are identical.

Q: Will the Bivar 5GD work as a drop-in replacement for the 5SGD? A: Yes. The 5GD is mechanically and electrically compatible with the 5SGD. Both use identical T-1 3/4 radial through-hole packages, mounting dimensions (8.50mm max height), and electrical parameters (2.1V forward voltage, 20mA test current). No circuit modifications are required.

Q: Are there compliance differences between these parts? A: The Bivar 5GD carries ROHS3 compliance certification. The 5SGD compliance status is not specified in the available data. For applications requiring specific regulatory compliance, the 5GD is the preferred selection.

Q: Can I use the Bivar 5GD if my circuit was designed for the 5SGD's 30mcd brightness? A: The 5GD provides 25mcd brightness, a 16.7% reduction. This falls within typical design margins for status indication LEDs. Evaluate the specific application requirements; if exact brightness matching is critical, alternative suppliers with matching millicandela ratings should be considered.

Q: What packaging options are available for the 5GD? A: The Bivar 5GD is available in bulk packaging. The 5SGD was supplied in standard packaging configuration. Confirm packaging requirements with your procurement specifications before ordering.
