LED Circuit Board Indicator 5640100011F Equivalent & Substitute Parts

Part Overview

The Dialight 5640100011F is an LED Circuit Board Indicator (CBI) designed for through-hole, right-angle mounting applications. This 3mm T-1 LED features a 3-high configuration with mixed color output (Red x2, Blank x1) and diffused lens technology. The part operates at 2V with 30mA current rating and delivers 10mcd brightness at a 60° viewing angle. As an active product with ROHS3 compliance and unlimited moisture sensitivity rating, this component is suitable for standard industrial and commercial circuit board applications where space-constrained indicator solutions are required.

Substitute Part Grouping Explanation

Substitution eligibility for the 5640100011F is determined by the following critical parameters:

• Mounting Configuration: Through-hole, right-angle orientation must be maintained for PCB compatibility
• Physical Form Factor: 3mm T-1 lens size ensures mechanical fit within existing board layouts
• Electrical Specifications: Voltage rating (2V) and current rating (30mA) define circuit compatibility
• Optical Characteristics: Peak wavelength (635nm red spectrum), brightness (10mcd), and viewing angle (60°) determine functional performance
• Series Compatibility: Parts within the Dialight 564 series maintain design consistency
• Compliance Standards: ROHS3 compliance and MSL-1 rating ensure regulatory and environmental compatibility

The substitute part 5640100111F shares the same base product number (5640100), series designation, mounting type, voltage rating, wavelength, brightness, viewing angle, and compliance certifications. Differences in color configuration (Red x3 vs. Red x2/Blank x1), current rating (20mA vs. 30mA), and lens finish (Diffused, Tinted vs. Diffused) represent the primary technical variations.

Parameter Comparison

Engineering Selection Recommendations

Both the 5640100011F and 5640100111F are active Dialight products with identical ROHS3 compliance and MSL-1 ratings, confirming regulatory and environmental suitability for equivalent applications. The parts share the same base product number, series designation, mounting configuration, voltage rating, wavelength, brightness output, and viewing angle.

Selection between these parts depends on circuit-specific requirements:

• 5640100011F is appropriate for applications requiring mixed-color indication (two red LEDs with one blank position) and supporting 30mA current draw per circuit branch.
• 5640100111F is appropriate for applications requiring uniform red indication (three red LEDs) with lower current consumption (20mA) and tinted lens finish for enhanced color saturation.

Both parts maintain mechanical and electrical compatibility within the 564 series platform. The choice between them is determined by the specific color configuration and current budget of the target application.

Frequently Asked Questions (FAQ)

Q: Can 5640100111F replace 5640100011F in existing designs?

A: Mechanical and electrical compatibility is maintained. The primary differences are color configuration (Red x3 vs. Red x2/Blank x1), current rating (20mA vs. 30mA), and lens finish (Diffused, Tinted vs. Diffused). Substitution is valid only if the application circuit accommodates these variations.

Q: What is the significance of the color configuration difference?

A: The main part provides two active red indicators with one blank position, while the substitute provides three active red indicators. This affects the visual indication pattern and circuit design. Select based on the required number of indicator positions in your application.

Q: Does the current rating difference affect compatibility?

A: The substitute part operates at 20mA versus the main part's 30mA. If the circuit is designed for 30mA operation, the substitute will draw less current, which is generally acceptable. If the circuit is designed for lower current budgets, the main part may exceed available current capacity.

Q: Are both parts suitable for high-reliability applications?

A: Both parts carry ROHS3 compliance and MSL-1 (unlimited) moisture sensitivity ratings, confirming suitability for standard industrial and commercial environments. Compliance certifications are identical between the two parts.

Q: What is the difference between Diffused and Diffused, Tinted lens finishes?

A: Both provide diffused light distribution at 60° viewing angle. The Tinted finish on the substitute part enhances color saturation of the red wavelength (635nm), potentially improving visual contrast in certain lighting conditions.
