LED Circuit Board Indicator 5650F5LC Equivalent & Substitute Parts

Part Overview

The 5650F5LC is a 3mm green LED circuit board indicator manufactured by Visual Communications Company (VCC). This component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing design requirements and production continuity. The 5650F5LC features a single green diffused, tinted lens with right-angle through-hole mounting, designed for 1.8V operation at 7mA current draw. Due to its obsolete status, active equivalent parts are required to maintain system functionality and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5650F5LC are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Color: Green (565nm peak wavelength)
• Configuration: Single LED
• Lens Size: 3mm, T-1 form factor
• Mounting Type: Through Hole, Right Angle
• Lens Type: Diffused construction
• RoHS3 Compliance and REACH Unaffected status

Secondary Compatibility Factors:

• Voltage Rating: 1.8V to 2.1V operating range
• Current Rating: 7mA to 20mA operational range
• Millicandela Rating: 1.6mcd to 30mcd brightness range

The identified substitutes maintain the core mechanical and optical characteristics of the original part while offering active product status and improved availability. Substitution is valid when the replacement part operates within the specified voltage and current parameters of the target application circuit.

Engineering Selection Recommendations

HLMP1790101F (Dialight) - Primary Substitute

The HLMP1790101F is the closest electrical and mechanical equivalent to the 5650F5LC. Both parts operate at identical voltage (1.8V) and current (7mA) specifications, ensuring direct circuit compatibility without modification. The HLMP1790101F maintains ROHS3 compliance and MSL 1 rating. This part is currently in active production status with 1799 units available in inventory. The 50° viewing angle and 1.6mcd brightness rating provide functional equivalence for standard circuit board indicator applications.

SSF-LXH103GD (Lumex Opto/Components Inc.) - Secondary Substitute

The SSF-LXH103GD is functionally compatible with the 5650F5LC for applications where higher brightness output is acceptable. This part operates at 2.1V and 20mA, requiring circuit verification to confirm voltage and current compatibility before implementation. The SSF-LXH103GD delivers 30mcd brightness with a 60° viewing angle, providing enhanced visibility in applications requiring higher luminous intensity. This part maintains ROHS3 compliance and MSL 1 rating with 19351 units in inventory. Selection of this substitute requires confirmation that the application circuit can supply the higher voltage and current specifications.

Frequently Asked Questions (FAQ)

Q: Can the HLMP1790101F directly replace the 5650F5LC without circuit modification?

A: Yes. The HLMP1790101F operates at identical 1.8V and 7mA specifications as the 5650F5LC, enabling direct substitution in existing circuit designs without component or resistor changes.

Q: What are the key differences between the two active substitutes?

A: The HLMP1790101F matches the original 5650F5LC voltage and current ratings (1.8V, 7mA) with 1.6mcd brightness. The SSF-LXH103GD operates at higher specifications (2.1V, 20mA) with significantly higher brightness (30mcd). Selection depends on circuit voltage/current capability and brightness requirements.

Q: Is the SSF-LXH103GD suitable for all 5650F5LC applications?

A: The SSF-LXH103GD requires circuit verification. The higher voltage (2.1V vs 1.8V) and current (20mA vs 7mA) specifications must be confirmed compatible with the target application before substitution.

Q: Do all substitute parts maintain the same physical form factor?

A: Yes. All substitute parts feature 3mm T-1 through-hole right-angle mounting, maintaining identical mechanical compatibility with the original 5650F5LC.

Q: Are compliance certifications maintained across all parts?

A: Yes. The 5650F5LC, HLMP1790101F, and SSF-LXH103GD all maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 moisture sensitivity rating.

Q: What is the primary reason for substitution?

A: The 5650F5LC is classified as obsolete. The HLMP1790101F and SSF-LXH103GD are active production parts with established supply chain availability, ensuring long-term component sourcing for new designs and production continuity.
