Key Parameters

Substitute Part Grouping Explanation

The Dialight 5913501831F qualifies as a direct substitute based on the following alignment of critical parameters:

Matching Parameters:

• Manufacturer: Dialight (same manufacturer ensures design compatibility)
• Series: 591 (same product family)
• Color Configuration: Red, Green, Blue (RGB) single configuration
• Mounting Type: Surface Mount, Right Angle (identical mechanical interface)
• Lens Type: Diffused (same optical characteristics)
• Viewing Angle: 40° (identical viewing specification)
• REACH Status: REACH Unaffected (same regulatory compliance)
• ECCN: EAR99 (same export classification)

Allowable Variations:

• Lens Size: 5mm (increased from 3mm) - larger form factor within same mounting interface
• Current Rating: 30mA Red, 20mA Green, 20mA Blue (red channel increased; green and blue maintained)
• Voltage Rating: 1.9V Red, 3.4V Green, 3.4V Blue (minor reductions within operational tolerance)
• Millicandela Rating: 60mcd Red, 150mcd Green, 30mcd Blue (maintained or slightly reduced brightness)
• Moisture Sensitivity Level: 2A (4 Weeks) (improved from 2, 1 Year)
• Product Status: Active (production available)

Engineering Selection Recommendations

The Dialight 5913501831F is the direct substitute for the obsolete 5913501002F. Selection of this substitute is supported by:

Product Status: The substitute part is active and in production, ensuring long-term availability and supply chain continuity. The original part is obsolete and no longer manufactured.

Regulatory Compliance: Both parts maintain REACH Unaffected status and EAR99 export classification. The substitute achieves ROHS3 compliance, meeting current environmental standards.

Mechanical Compatibility: Both parts feature identical surface mount, right-angle mounting interfaces. The increased lens size (5mm vs. 3mm) represents a physical enlargement that may require PCB layout adjustment but maintains the same mounting footprint classification.

Electrical Compatibility: The substitute operates within compatible voltage and current ranges. Red channel current increases to 30mA while green and blue channels remain at 20mA. Voltage ratings are slightly reduced but remain within standard LED operational parameters. Brightness levels are maintained or slightly reduced, ensuring adequate illumination for indicator applications.

Frequently Asked Questions (FAQ)

Q: Can the 5913501831F directly replace the 5913501002F without circuit modification?

A: The substitute part uses the same mounting interface and electrical configuration for green and blue channels. The red channel current increases from 20mA to 30mA, requiring circuit current-limiting resistor adjustment. PCB layout may require modification due to the increased 5mm lens diameter compared to the original 3mm size.

Q: What is the primary reason for substitution?

A: The original part 5913501002F is obsolete and no longer manufactured. The 5913501831F is an active product from the same manufacturer and series, providing continued availability for new designs and production requirements.

Q: Are there differences in brightness between the two parts?

A: Red and green channels maintain comparable brightness levels (60mcd and 150mcd respectively). The blue channel shows a slight reduction from 37mcd to 30mcd. These differences are within acceptable ranges for indicator applications.

Q: How do the voltage ratings differ?

A: The substitute operates at slightly lower voltages: 1.9V red (vs. 2V), 3.4V green and blue (vs. 4.6V and 3.6V). These reductions are minor and do not affect standard circuit operation.

Q: What is the impact of the larger lens size?

A: The 5mm lens (vs. 3mm) provides a larger visual indicator with identical 40° viewing angle. PCB layout and mechanical clearance must accommodate the increased diameter. The mounting interface remains compatible.

Q: Does the substitute meet current environmental standards?

A: Yes. The 5913501831F is ROHS3 compliant, meeting current environmental regulations. Both parts maintain REACH Unaffected status.
