Dialight 5640100111 LED Circuit Board Indicator Equivalent & Substitute Parts

Part Overview

The Dialight 5640100111 is a 3-High red LED circuit board indicator featuring a 3mm T-1 through-hole right-angle configuration with diffused, tinted lens. This part operates at 2V with 20mA current and delivers 10mcd brightness at a 60° viewing angle. The original part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Active alternatives from Dialight and cross-manufacturer options are available with compatible electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5640100111 is determined by strict alignment of the following critical parameters:

Electrical Compatibility Requirements:

• Voltage Rating: 2V (exact match required)
• Current: 20mA (exact match required)
• Color Configuration: Red (x 3) (exact match required)

Mechanical Compatibility Requirements:

• Mounting Type: Through Hole, Right Angle (exact match required)
• Lens Size: 3mm, T-1 (exact match required)
• Configuration: 3 High (exact match required)

Optical Characteristics:

• Lens Type: Diffused, Tinted (exact match required)
• Wavelength Peak: 635nm (Dialight parts) or 627nm (Kingbright alternative)
• Millicandela Rating: 10mcd (Dialight parts) or 22.5mcd (Kingbright alternative)
• Viewing Angle: 60° (Dialight parts) or 40° (Kingbright alternative)

Substitute parts are grouped into two categories: direct Dialight replacements with identical specifications and active product status, and a cross-manufacturer alternative from Kingbright with minor optical parameter variations within acceptable tolerance for circuit board indicator applications.

Parameter Comparison

Engineering Selection Recommendations

Dialight Direct Replacements (5640100111F, 56401401114F, 5640140111F):

All three Dialight alternatives are active products with ROHS3 compliance, addressing the RoHS non-compliance status of the obsolete 5640100111. These parts maintain identical electrical specifications (2V, 20mA) and optical characteristics (635nm wavelength, 10mcd, 60° viewing angle). Selection among these three Dialight options depends on packaging requirements and lens style specification availability. Part 5640100111F offers bulk packaging with unspecified lens style details. Parts 56401401114F and 5640140111F provide bulk packaging with confirmed round domed top lens style and 3mm T-1 lens size specifications.

Kingbright Cross-Manufacturer Alternative (WP934SA/3ID):

The Kingbright WP934SA/3ID maintains full electrical compatibility (2V, 20mA) and mechanical compatibility (3mm T-1 through-hole right-angle 3-high configuration) with the original part. Optical parameters differ: wavelength is 627nm (versus 635nm), millicandela rating is 22.5mcd (versus 10mcd), and viewing angle is 40° (versus 60°). This part is ROHS3 compliant and supplied in tube packaging. The increased brightness and narrower viewing angle represent functional differences suitable for applications where higher intensity or focused illumination is acceptable.

Frequently Asked Questions (FAQ)

Q: Can I use 5640100111F as a direct replacement for the obsolete 5640100111?

A: Yes. The 5640100111F maintains identical electrical specifications (2V, 20mA), color configuration (red 3-high), and mounting type (through-hole right-angle). Both parts operate at 635nm wavelength with 10mcd brightness and 60° viewing angle. The primary difference is product status: 5640100111F is active and ROHS3 compliant, whereas the original is obsolete and RoHS non-compliant.

Q: What is the difference between the three Dialight substitute options?

A: All three Dialight parts (5640100111F, 56401401114F, 5640140111F) share identical electrical and optical specifications. The differences are in documentation completeness: 5640100111F does not specify lens style or size details, while 56401401114F and 5640140111F explicitly confirm round domed top lens style and 3mm T-1 lens size. All three are supplied in bulk packaging.

Q: Can I use the Kingbright WP934SA/3ID instead of a Dialight part?

A: The Kingbright WP934SA/3ID is electrically and mechanically compatible but has different optical characteristics. It delivers 22.5mcd brightness (versus 10mcd) at a narrower 40° viewing angle (versus 60°) with a slightly different wavelength of 627nm (versus 635nm). This part is suitable for applications where higher intensity or focused illumination is required. Verify that the increased brightness and narrower viewing angle are acceptable for your specific circuit board indicator application.

Q: What packaging options are available?

A: Dialight parts 5640100111F, 56401401114F, and 5640140111F are supplied in bulk packaging. The Kingbright WP934SA/3ID is supplied in tube packaging. Select based on your procurement and assembly process requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts (5640100111F, 56401401114F, 5640140111F, and WP934SA/3ID) are ROHS3 compliant. The original 5640100111 is RoHS non-compliant. If RoHS compliance is required for your application, any of the substitute parts will satisfy this requirement.

Q: What is the inventory status of these parts?

A: The original 5640100111 has 740 pieces in stock. Active substitutes have higher availability: 5640100111F (1924 pcs), 56401401114F (789 pcs), 5640140111F (675 pcs), and WP934SA/3ID (20165 pcs). Kingbright WP934SA/3ID offers the highest inventory level.
