Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5511201010F is determined by strict equivalence across the following critical parameters:

• Color specification (Yellow, 585nm peak wavelength)
• Electrical ratings (1.8V voltage, 2mA current)
• Optical output (1.6mcd brightness)
• Viewing angle (60°)
• Physical form factor (3mm T-1, round domed top lens)
• Mounting configuration (Through hole, right angle)
• Lens characteristics (Diffused, tinted)

The substitute part 5511207F meets all these criteria and is classified as a direct equivalent within the Dialight 551 series. Both components share identical electrical, optical, and mechanical specifications, ensuring functional interchangeability in circuit board indicator applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 5511201010F and 5511207F are active products from Dialight's 551 series with identical electrical, optical, and mechanical specifications. Both components maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial and commercial applications.

Selection between these parts should be based on supply chain availability and inventory status. The 5511207F currently maintains higher inventory levels (1529 pcs) compared to the 5511201010F (973 pcs), making it a viable alternative when primary part availability is constrained.

Frequently Asked Questions (FAQ)

Q: Can the 5511207F be used as a direct replacement for the 5511201010F?

A: Yes. Both parts are functionally equivalent with identical voltage ratings (1.8V), current consumption (2mA), brightness output (1.6mcd), color specification (yellow, 585nm), viewing angle (60°), and physical form factor (3mm T-1 through-hole right-angle mount). No circuit modifications are required.

Q: Are there any compliance differences between these parts?

A: No. Both components carry identical RoHS3 compliance and REACH unaffected status, ensuring compatibility with current regulatory frameworks.

Q: What determines substitution eligibility for this LED indicator?

A: Substitution is based on exact equivalence across voltage rating, current consumption, optical output (millicandela), color and wavelength, viewing angle, lens type and style, physical dimensions, and mounting configuration. Deviations in any of these parameters disqualify a part from direct substitution.

Q: Are there packaging considerations when switching between these parts?

A: Both parts are supplied in bulk packaging. No special handling or storage modifications are required when transitioning between the 5511201010F and 5511207F.
