Bivar Inc. 5GC LED Green Clear T-1 3/4 Through Hole - Equivalent & Substitute Parts

Part Overview

The Bivar Inc. 5GC is an active green LED indicator lamp in T-1 3/4 form factor, designed for discrete indication applications requiring radial through-hole mounting. This green LED operates at 2.1V forward voltage with 40mcd luminous intensity and features a clear, domed lens for standard visibility applications. The part is ROHS3 compliant and maintains unlimited moisture sensitivity rating (MSL 1), making it suitable for general industrial and consumer electronics applications.

Substitute parts become necessary when design requirements demand higher luminous intensity, different spectral output, or when supply chain constraints affect primary component availability. Alternative models within this category maintain identical electrical operating parameters and physical form factors while offering varied optical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bivar Inc. 5GC is determined by strict conformance to the following electrical and mechanical parameters:

Critical Fixed Parameters (Non-Negotiable for Substitution):

• Forward voltage (Vf): 2.1V
• Lens size: 5mm, T-1 3/4
• Mounting type: Through Hole (Radial)
• Color: Green
• Package type: Radial
• Lens transparency: Clear
• Configuration: Standard
• RoHS compliance status

Allowed Variable Parameters (May Differ Between Substitutes):

• Millicandela rating (luminous intensity)
• Current - Test
• Viewing angle
• Wavelength (dominant and peak)
• Height (maximum)
• Manufacturer identity

All three substitute parts (5219201F, LTL-4238, LTL2P3KGKNN) meet the critical fixed parameters, enabling direct functional substitution within applications designed for the 5GC base component.

Parameter Comparison

Engineering Selection Recommendations

Product Status Compliance: All four parts maintain active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), establishing baseline compatibility for general industrial applications.

Radial Through-Hole Substitutes (Direct PCB Mount): The Lite-On LTL-4238 and LTL2P3KGKNN, along with the Bivar 5GC, feature identical radial through-hole mounting configuration. These three parts are interchangeable at the PCB level without mechanical modification. The LTL-4238 offers moderate luminous intensity increase (90mcd) while maintaining reduced test current (10mA) and narrower viewing angle (16°). The LTL2P3KGKNN provides significantly elevated luminous intensity (980mcd) with standard test current (20mA) and intermediate viewing angle (22°).

Flange-Mount Substitute (Incandescent Replacement): The Dialight 5219201F features midget flange base configuration, designed for direct incandescent lamp socket replacement applications. This part operates at 60mcd luminous intensity and is documented for use in indicator light and incandescent replacement applications. Selection of this part requires compatible flange-mount socket infrastructure, distinct from radial through-hole PCB applications.

Selection Basis: Component selection within this substitution group depends exclusively on matching mechanical mounting infrastructure (radial through-hole versus flange base) and required luminous intensity specifications. All parts maintain identical forward voltage, color specification, and regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can the Dialight 5219201F replace the Bivar 5GC in a radial through-hole PCB application? A: No. The 5219201F features midget flange base configuration for socket-mount applications, while the 5GC requires radial through-hole PCB mounting. Mechanical incompatibility prevents substitution in radial through-hole designs. Select LTL-4238 or LTL2P3KGKNN for radial through-hole applications.

Q: What is the relationship between luminous intensity and viewing angle among the radial substitutes? A: The Bivar 5GC provides 40mcd with 35° viewing angle. The Lite-On LTL-4238 increases intensity to 90mcd with narrower 16° viewing angle. The Lite-On LTL2P3KGKNN reaches 980mcd with 22° viewing angle. Higher luminous intensity correlates with narrower effective viewing angle in this product series.

Q: Do all parts maintain identical forward voltage specifications? A: Yes. All four parts (5GC, 5219201F, LTL-4238, LTL2P3KGKNN) operate at 2.1V forward voltage (typical), enabling circuit design compatibility across the substitution group.

Q: Are there RoHS or environmental compliance differences among these parts? A: No. All four parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Regulatory and environmental compliance status is identical across the entire group.

Q: What mounting limitations exist for each part? A: The Bivar 5GC, Lite-On LTL-4238, and Lite-On LTL2P3KGKNN require radial through-hole PCB mounting. The Dialight 5219201F requires midget flange base socket mounting. Mounting infrastructure compatibility is the primary mechanical constraint determining substitutability.

Q: How do wavelength specifications differ among substitutes? A: Peak wavelengths range from 565nm (5219201F and LTL-4238) to 575nm (LTL2P3KGKNN), with the Bivar 5GC at 568nm. These variations fall within standard green LED spectral output ranges and do not affect functional color classification or perception in typical indicator applications.
