Dialight 5511207 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5511207 is a 3mm T-1 through-hole right-angle LED circuit board indicator featuring a single yellow diffused lens with domed top. Rated at 1.8V and 2mA, this component delivers 1.6mcd at a 60° viewing angle with a peak wavelength of 585nm. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. Active alternatives from the same manufacturer series provide direct functional replacement with improved availability and compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Dialight 5511207 is determined by strict equivalence across the following critical parameters:

Direct Substitutes (Dialight Series 551): Parts 5511201010F, 5511201F, 5511203F, 5511207003F, 5511207010F, and 5511207F maintain identical electrical and mechanical specifications: 1.8V voltage rating, 2mA current, 1.6mcd brightness, 585nm peak wavelength, 60° viewing angle, diffused tinted lens, round domed top, 3mm T-1 form factor, and through-hole right-angle mounting. These parts differ only in packaging configuration (bulk) and product status (active vs. obsolete). All direct substitutes carry ROHS3 compliance and REACH unaffected status.

Similar Alternative (Cross-Manufacturer): The Bivar Inc. H101CYDL represents a similar but not equivalent alternative. While it shares the yellow color, 3mm T-1 form factor, diffused lens, round domed top, and through-hole right-angle mounting, it differs in voltage rating (2V vs. 1.8V), viewing angle (40° vs. 60°), brightness (2mcd vs. 1.6mcd), and peak wavelength (590nm vs. 585nm). This part is suitable only when circuit design accommodates the higher voltage and reduced viewing angle.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: Select any of the active Dialight Series 551 substitutes (5511201010F, 5511201F, 5511203F, 5511207003F, 5511207010F, or 5511207F). All maintain identical electrical performance and mechanical compatibility with the obsolete 5511207. The 5511207F offers the highest inventory availability (1529 pcs) and is the preferred choice for new production. All direct substitutes carry ROHS3 compliance, providing regulatory advantage over the original part.

For Cross-Manufacturer Alternative: The Bivar Inc. H101CYDL is suitable only when circuit design accommodates a 2V supply voltage (vs. 1.8V) and accepts reduced viewing angle (40° vs. 60°). The higher brightness (2mcd vs. 1.6mcd) may provide operational benefit in certain applications but represents a design change rather than a true equivalent substitution.

Frequently Asked Questions (FAQ)

Q: Can I use 5511207F as a direct replacement for 5511207? A: Yes. The 5511207F is electrically and mechanically identical to 5511207, differing only in product status (active vs. obsolete) and packaging (bulk). It carries ROHS3 compliance and maintains all critical parameters: 1.8V, 2mA, 1.6mcd, 585nm, 60° viewing angle, and 3mm T-1 through-hole right-angle mounting.

Q: What is the difference between 5511201F and 5511207F? A: Both parts are functionally equivalent with identical electrical and optical specifications. The difference lies in base product number designation (5511201 vs. 5511207) and packaging configuration. Selection between them depends on procurement availability and packaging requirements (both available in bulk).

Q: Why does the Bivar H101CYDL have different specifications? A: The H101CYDL is a cross-manufacturer alternative, not a direct equivalent. It operates at 2V (vs. 1.8V), has a 40° viewing angle (vs. 60°), and 2mcd brightness (vs. 1.6mcd). Use this part only when your circuit design accommodates these parameter differences.

Q: Are all substitute parts ROHS3 compliant? A: All active Dialight Series 551 substitutes (5511201010F, 5511201F, 5511203F, 5511207003F, 5511207010F, 5511207F) are ROHS3 compliant. The original 5511207 does not list RoHS status. The Bivar H101CYDL is also ROHS3 compliant.

Q: What packaging options are available for substitutes? A: All Dialight Series 551 direct substitutes are available in bulk packaging. The Bivar H101CYDL is available in tray packaging. Confirm packaging requirements with your procurement process.

Q: Can I mix different substitute part numbers in the same assembly? A: Yes. All Dialight Series 551 substitutes are functionally identical and can be used interchangeably within the same circuit board design without performance variation.
