4300F5LC Equivalent & Substitute Parts

Part Overview

The 4300F5LC is a green diffused LED indicator manufactured by Visual Communications Company (VCC) in a T-1 through-hole package. This component is classified as "Not For New Designs," indicating it has reached end-of-life status. The part operates at 1.8V forward voltage with a 2mA test current and delivers 1.6 millicandela of luminous intensity through a 50° viewing angle. Due to its discontinued status, equivalent substitute parts from active manufacturers are necessary for ongoing production requirements and design continuity.

Substitute Part Grouping Explanation

Substitution of the 4300F5LC is determined by the following critical parameters:

Primary Compatibility Criteria:

Lens size: 3mm, T-1 form factor
Lens transparency: Diffused
Color: Green
Mounting type: Through hole, radial configuration
Package type: Radial

Secondary Electrical Parameters:

Forward voltage (Vf): 1.8V nominal
Test current: 2mA nominal
Millicandela rating: 1.6mcd nominal
Viewing angle: 50° nominal
Peak wavelength: 565nm nominal

Substitute parts are grouped into two categories based on electrical compatibility:

Category A - Direct Electrical Equivalents (1.8V–2.1V, 2mA–2mA test current): Parts that operate within the same voltage and current range as the original 4300F5LC, suitable for direct replacement in low-voltage applications.

Category B - Higher Voltage/Current Variants (5V–12V, 10mA–13mA test current): Parts that require different circuit design considerations due to elevated forward voltage and test current specifications. These are suitable only when circuit topology accommodates the higher electrical requirements.

Category C - Brightness Variants: Parts with differing millicandela ratings but compatible form factors and mounting. Selection depends on application visibility requirements.

Engineering Selection Recommendations

Recommended Primary Substitutes (Direct Replacement Category):

The HLMP-1790 and HLMP-1790-A0002 from Broadcom Limited are the preferred substitutes for the 4300F5LC. Both parts maintain active product status and meet the following criteria:

Forward voltage of 1.9V operates within the 1.8V specification with minimal circuit impact
Test current of 2mA matches the original specification exactly
T-1 3mm form factor and radial through-hole mounting are identical
Peak wavelength of 565nm matches the original specification
Physical height of 6.35mm is identical to the original
ROHS3 compliance and MSL-1 rating match the original certifications
Broadcom Limited maintains active manufacturing status, ensuring long-term availability

The HLMP-1790-A0002 variant is supplied in cut tape packaging, while HLMP-1790 is supplied in bulk packaging. Selection between these two depends on procurement and assembly requirements.

Secondary Substitutes (Electrical Compatibility with Design Considerations):

The 3GDL-F from Bivar Inc. operates at 2.1V forward voltage with 2mA test current. This part is suitable for applications where the additional 0.3V forward voltage drop can be accommodated in the circuit design. The 4mcd brightness rating is higher than the original 1.6mcd, which may affect visual appearance in the application. The 35° viewing angle is narrower than the original 50°, which may impact visibility in certain mounting orientations.

Higher Voltage Variants (Circuit Redesign Required):

The HLMP-1640, HLMP-1640-B00A1, HLMP-1640-B00A2, and HLMP-1641 from Broadcom Limited operate at 5V and 12V respectively. These parts require circuit topology modifications and are suitable only when the application power supply and current-limiting resistor design can be adjusted to accommodate the higher voltage specifications. These variants maintain identical 1.6mcd brightness and 565nm wavelength characteristics.

Not Recommended:

The 264-7SYGD/S530-E2 from Everlight Electronics is a yellow-green LED with 573nm dominant wavelength, which differs from the green specification of the original part. This part is suitable only for applications where yellow-green color is acceptable. The 151031VS06000 from Würth Elektronik operates at 2.2V with 20mA test current, requiring significant circuit redesign and is not recommended for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can the HLMP-1790 be used as a direct replacement for the 4300F5LC without circuit modifications?

A: The HLMP-1790 operates at 1.9V forward voltage compared to the 4300F5LC's 1.8V specification. In most low-voltage indicator applications with current-limiting resistors, this 0.1V difference produces negligible impact on circuit operation. However, the specific circuit design must be evaluated to confirm the resistor value and power supply voltage accommodate this variation. Both parts operate at identical 2mA test current and maintain the same T-1 form factor.

Q: What is the difference between HLMP-1790 and HLMP-1790-A0002?

A: Both parts are electrically and mechanically identical. The primary difference is packaging: HLMP-1790 is supplied in bulk packaging, while HLMP-1790-A0002 is supplied in cut tape (CT) format. Selection depends on assembly equipment compatibility and procurement preferences. Both maintain active product status and identical electrical specifications.

Q: Why is the 3GDL-F not recommended as a primary substitute despite matching the 2mA test current?

A: While the 3GDL-F operates at 2mA test current, it differs from the 4300F5LC in three key parameters: forward voltage (2.1V vs. 1.8V), brightness (4mcd vs. 1.6mcd), and viewing angle (35° vs. 50°). The higher brightness may alter the visual appearance in the application, and the narrower viewing angle reduces visibility in certain mounting orientations. The 0.3V voltage increase requires circuit evaluation. These factors make it a secondary choice when the HLMP-1790 series is available.

Q: Can the HLMP-1640 or HLMP-1641 be used in place of the 4300F5LC?

A: The HLMP-1640 (5V) and HLMP-1641 (12V) require complete circuit redesign. These parts operate at significantly higher forward voltages and test currents than the 4300F5LC. The current-limiting resistor value and power supply voltage must be recalculated to accommodate the higher electrical requirements. These variants are suitable only when the application circuit can be modified to support 5V or 12V operation. Direct substitution without circuit modification will result in component failure or incorrect operation.

Q: What does "Not For New Designs" status mean for the 4300F5LC?

A: "Not For New Designs" indicates the 4300F5LC has reached end-of-life status and is no longer recommended for new product development. Existing inventory may be available, but the manufacturer has discontinued active production and support. For new designs and ongoing production, active-status substitutes such as the HLMP-1790 series from Broadcom Limited are required to ensure long-term component availability and manufacturing continuity.

Q: Are all substitute parts ROHS3 compliant like the original 4300F5LC?

A: All substitute parts listed in this reference maintain ROHS3 compliance status, matching the original 4300F5LC certification. All parts also maintain MSL-1 (Unlimited) moisture sensitivity level rating. Compliance certifications are consistent across all recommended substitutes.

Q: What is the significance of the 565nm peak wavelength specification?

A: The 565nm peak wavelength defines the green color output of the LED. The 4300F5LC and most recommended substitutes (HLMP-1790, HLMP-1640, HLMP-1641) maintain this 565nm specification, ensuring consistent color appearance across substitutions. The 3GDL-F operates at 568nm, which is within the green spectrum but slightly shifted. The 264-7SYGD/S530-E2 operates at 575nm, which produces a yellow-green appearance and is not recommended for direct color matching.

Q: How does the viewing angle affect component selection?

A: The viewing angle determines the cone of light distribution from the LED. The 4300F5LC specifies 50°, meaning the LED produces visible light within a 50-degree cone. The HLMP-1790 maintains this 50° specification. The 3GDL-F specifies 35°, which is narrower and may reduce visibility when the LED is not directly aligned with the observer. The HLMP-1640 and HLMP-1641 specify 60°, providing wider visibility. Application mounting orientation and visibility requirements determine whether viewing angle differences are acceptable.
