Key Parameters

Substitute Part Grouping Explanation

The substitute part 5640100111F is classified as a direct equivalent based on the following critical parameters:

• Voltage Rating: Both parts operate at 2V, ensuring compatible power supply requirements
• Wavelength - Peak: Both emit at 635nm red spectrum, maintaining consistent optical characteristics
• Millicandela Rating: Both deliver 10mcd brightness output
• Viewing Angle: Both provide 60° viewing angle
• Mounting Type: Both use through-hole, right-angle configuration
• Series & Base Product: Both belong to Dialight 564 series with base number 5640100
• Compliance: Both are ROHS3 compliant and REACH unaffected

The primary difference is the current rating (30mA vs. 20mA) and LED color configuration (1 red + 2 blank vs. 3 red), which do not prevent substitution in applications where the lower current draw is acceptable.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain Active product status and full ROHS3 compliance with MSL 1 rating, ensuring long-term availability and regulatory adherence. The 5640100111F operates at 20mA versus the 5640100100F at 30mA, resulting in reduced power consumption and heat generation. This lower current requirement may be advantageous in power-constrained applications or designs requiring extended component lifespan.

The configuration difference (1 red + 2 blank vs. 3 red) should be evaluated against circuit board layout requirements. Both parts share identical optical and electrical core specifications, supporting direct substitution in applications where the current rating and LED position configuration are compatible with the design.

Frequently Asked Questions (FAQ)

Q: Can 5640100111F replace 5640100100F in existing designs? A: Yes, provided the circuit design accommodates the 20mA current rating and the 3-red LED configuration meets layout requirements. The core optical and electrical parameters are identical.

Q: What is the primary difference between these parts? A: The main differences are current rating (30mA vs. 20mA) and LED color configuration (1 red + 2 blank vs. 3 red). Both deliver identical brightness (10mcd) and wavelength (635nm).

Q: Are both parts RoHS compliant? A: Yes, both 5640100100F and 5640100111F are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Does the lens type difference affect substitution? A: The 5640100100F features a diffused lens while 5640100111F uses a diffused, tinted lens. Both maintain the same 60° viewing angle and 10mcd brightness output. Lens tinting may affect color perception but does not prevent functional substitution.

Q: What mounting considerations apply to both parts? A: Both parts use through-hole, right-angle mounting on 3mm T-1 form factor, ensuring mechanical compatibility with standard PCB layouts designed for this package type.
