Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5GC4.030 is determined by alignment across the following critical parameters:

• Lens Size & Form Factor: 5mm through-hole radial configuration with round, domed-top lens
• Color & Wavelength Range: Green light indication (peak wavelength 525nm nominal)
• Electrical Characteristics: Forward voltage (Vf) in the 3.4V to 3.8V range, designed for 20mA test current
• Optical Performance: Brightness level (4000mcd to 4200mcd range) and viewing angle (30°)
• Mechanical Compatibility: Package type (radial), mounting method (through-hole), maximum height tolerance
• Environmental Classification: Moisture Sensitivity Level 1 (unlimited)
• Regulatory Compliance: ECCN EAR99, HTSUS code 8541.41.0000

The identified substitute part (5219947F by Dialight) meets these requirements within acceptable engineering tolerances for direct circuit replacement.

Parameter Comparison

Engineering Selection Recommendations

The 5219947F (Dialight) is qualified as a direct substitute for the obsolete 5GC4.030 based on the following criteria:

Product Status: The 5219947F carries active product status, ensuring ongoing availability and manufacturing support. The 5GC4.030 is classified as obsolete, making the transition to an active equivalent component critical for long-term supply chain reliability.

Regulatory Compliance: Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. The 5219947F carries ROHS3 Compliant and REACH Unaffected certifications, meeting modern regulatory standards for electronics manufacturing and distribution.

Electrical & Optical Compatibility: Forward voltage differential (3.4V vs. 3.8V, a 0.4V variance) falls within acceptable tolerance for typical LED circuit designs with current-limiting resistors. Test current specification (20mA) is identical. Millicandela rating difference (4000mcd vs. 4200mcd) represents a 5% increase in brightness, maintaining visibility requirements for indication applications. Wavelength specifications (peak 525nm vs. 518nm) confirm both components operate within the green spectrum suitable for human perception.

Form Factor & Mechanical Compatibility: Both parts feature 5mm through-hole radial packages with round, domed-top clear lenses. Height difference (8.80mm vs. 9.65mm, a 0.85mm variance) remains within tolerance for standard PCB-mounted LED applications and does not create clearance conflicts in typical enclosure designs.

Environmental Rating: Both parts carry MSL 1 (Unlimited) classification, indicating identical moisture handling and storage requirements.

Selection of the 5219947F for new designs or production restart requires circuit verification of the 0.4V forward voltage increase to confirm adequacy of existing current-limiting resistor values for target brightness output.

Frequently Asked Questions (FAQ)

Q: Can the 5219947F directly replace the 5GC4.030 without circuit modifications?

A: The 5219947F is mechanically and functionally compatible with the 5GC4.030 for through-hole PCB mounting. However, the forward voltage difference (3.8V vs. 3.4V) may require verification of current-limiting resistor values to confirm the desired brightness output is maintained. No modifications to PCB layout or footprint are necessary.

Q: What is the significance of the forward voltage difference between these parts?

A: The 0.4V increase in forward voltage (3.4V to 3.8V) affects the voltage drop across the LED in circuit. In designs with fixed supply voltages and current-limiting resistors, this variance reduces the voltage available for the current-limiting resistor by 0.4V. For most 5V-based circuits, this remains within acceptable operating range. Verification of actual LED current (and therefore brightness) is recommended through circuit analysis or measurement if critical brightness levels are specified.

Q: Are both parts suitable for high-volume production?

A: The 5GC4.030 is classified as obsolete and carries inventory of 805 units. The 5219947F is classified as active with 1050 units in stock and carries ROHS3 Compliant certification, indicating suitability for ongoing manufacturing in compliance with modern electronics regulations. New designs should specify the 5219947F.

Q: What is the significance of the dominant wavelength (527nm) for the 5219947F?

A: The dominant wavelength (527nm) represents the peak wavelength where human eye perception of the green color is most concentrated. The peak wavelength specification (518nm) indicates the actual wavelength with maximum optical power output from the LED. Both parameters confirm the part produces green light suitable for indication applications. The difference between dominant and peak wavelength is a normal characteristic of LED spectral output.

Q: Are there any height or mechanical spacing concerns when substituting?

A: The 5219947F height of 9.65mm versus the 5GC4.030 height of 8.80mm represents a 0.85mm increase. This difference does not create conflicts with standard PCB assembly, component spacing, or typical enclosure clearances. Verification is necessary only in applications with height-constrained designs (such as low-profile assemblies or custom mechanical fixtures).

Q: What is MSL 1 (Unlimited) and how does it affect component handling?

A: MSL (Moisture Sensitivity Level) 1 (Unlimited) indicates the component is not sensitive to moisture absorption during storage or handling. No baking or desiccant storage is required before soldering. Standard component storage and handling procedures are appropriate.
