Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 5111F7 is determined by strict alignment of the following critical parameters:

Electrical Compatibility:

• Forward voltage (Vf) must be 2.1V typical to maintain circuit compatibility
• Peak wavelength must be 585nm to ensure color consistency (yellow spectrum)
• Termination style must be Wire Wrap to support existing assembly methods

Mechanical Compatibility:

• Panel cutout shape must be round
• Panel cutout dimensions must be 0.16" (4.06mm) to fit existing panel openings
• Lens size must be 3mm, T-1 standard form factor
• Lens style must be round with domed top for optical and aesthetic consistency

Regulatory and Environmental Compliance:

• RoHS3 compliance required
• REACH Unaffected status required
• Moisture Sensitivity Level (MSL) of 1 (Unlimited) required

The substitute part 5580301001F from Dialight meets all critical substitution criteria while offering active product status and improved availability.

Engineering Selection Recommendations

The 5580301001F from Dialight is the qualified substitute for the obsolete 5111F7. Selection of this substitute is based on the following engineering criteria:

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH Unaffected status, ensuring continued compliance with environmental and hazardous substance regulations.

Electrical Equivalence: The substitute maintains identical forward voltage (2.1V) and peak wavelength (585nm), ensuring direct circuit compatibility without modification to existing drive circuitry or current-limiting resistor calculations.

Mechanical Interchangeability: The substitute features identical panel cutout dimensions (0.16" / 4.06mm), lens size (3mm T-1), and lens style (round with domed top), enabling direct physical replacement in existing panel assemblies without mechanical redesign.

Product Status: The substitute is active in production, providing long-term availability and supply chain stability compared to the obsolete 5111F7.

Current Rating Consideration: The substitute operates at a maximum current of 20mA compared to the original 30mA rating. Circuit designs operating the original component at or below 20mA current levels require no modification. Designs requiring operation above 20mA must be evaluated for alternative solutions.

Luminous Intensity: The substitute provides 16mcd compared to the original 6.3mcd, resulting in increased brightness. This enhancement is compatible with applications where increased visibility is acceptable or beneficial.

Frequently Asked Questions (FAQ)

Q: Can the 5580301001F directly replace the 5111F7 in existing assemblies?

A: Yes, the 5580301001F is mechanically and electrically compatible for direct replacement. The identical panel cutout dimensions (0.16" / 4.06mm), lens form factor (3mm T-1 round domed), and forward voltage (2.1V) enable direct substitution without panel modification or circuit redesign.

Q: What is the impact of the different maximum current ratings (30mA vs. 20mA)?

A: The substitute operates at a maximum current of 20mA. If the original circuit design operates the 5111F7 at or below 20mA, no circuit modification is required. Designs requiring operation above 20mA must be evaluated for alternative components or circuit redesign.

Q: Does the increased brightness (16mcd vs. 6.3mcd) affect compatibility?

A: The increased luminous intensity of the substitute is compatible with applications where enhanced visibility is acceptable. Applications with specific brightness requirements below 16mcd should evaluate whether the increased output affects system performance or user experience.

Q: Are there any differences in viewing angle between the two components?

A: The substitute specifies a 40° viewing angle, while the original part does not provide a viewing angle specification. The 40° viewing angle of the substitute is typical for 3mm T-1 diffused LED lenses and is compatible with standard panel indicator applications.

Q: Do both components meet the same environmental and regulatory standards?

A: Yes, both components are ROHS3 compliant, REACH Unaffected, and feature Moisture Sensitivity Level 1 (Unlimited). No difference in environmental or regulatory compliance exists between the two components.

Q: What is the difference between the lens color specifications?

A: The original 5111F7 does not specify a lens color, while the substitute 5580301001F specifies yellow lens color. Both components feature diffused yellow lenses for yellow light emission at 585nm peak wavelength. The lens color specification in the substitute provides additional clarity regarding the optical properties.
