Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5611201080 is determined by the following critical parameters:

Electrical Compatibility Parameters:

• Color: Yellow (583nm peak wavelength)
• Current Rating: 2mA
• Voltage Rating: 1.9V
• Millicandela Rating: 1.8mcd
• Viewing Angle: 50°
• Configuration: Single

Mechanical Compatibility Parameters:

• Mounting Type: Through Hole
• Lens Type: Diffused

Allowable Variations:

• Lens Size: May differ (2.00mm to 5mm acceptable for through-hole mounting)
• Lens Style: May vary (Round with Flat Top to Round with Domed Top acceptable)
• Product Status: Active status preferred for ongoing availability
• RoHS Compliance: May upgrade to compliant status

The substitute part 5611201080F maintains all critical electrical parameters while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5611201080F serves as the direct substitute for the obsolete 5611201080. Both components share identical electrical specifications: 1.9V voltage rating, 2mA current draw, 1.8mcd brightness, 50° viewing angle, and 583nm peak wavelength yellow emission.

The primary distinction lies in product status and regulatory compliance. The 5611201080F maintains active production status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The original part's obsolete status necessitates transition to the substitute for new designs and ongoing production support.

Physical form factor differences exist: the substitute features a larger 5mm T-1 3/4 lens with domed top versus the original 2.00mm flat-top design. These dimensional changes do not affect electrical interchangeability but require PCB layout verification for mechanical fit within the intended application.

Frequently Asked Questions (FAQ)

Q: Are the electrical characteristics identical between 5611201080 and 5611201080F?

A: Yes. Both parts operate at 1.9V, draw 2mA, produce 1.8mcd brightness, and emit yellow light at 583nm peak wavelength with 50° viewing angle. Electrical performance is equivalent.

Q: What is the primary reason for substitution?

A: The original 5611201080 is classified as obsolete. The 5611201080F is an active production part from the same manufacturer and series, ensuring continued availability and supply chain reliability.

Q: Will the larger lens size of the 5611201080F affect my application?

A: The substitute features a 5mm T-1 3/4 lens compared to the original 2.00mm diameter. This dimensional change requires verification of PCB mounting hole spacing and mechanical clearance within your enclosure. Electrical function remains unchanged.

Q: Does the domed lens style impact optical performance?

A: Both parts use diffused lens technology with identical 50° viewing angles and 1.8mcd brightness ratings. The lens style difference (flat top versus domed top) does not alter the specified optical characteristics.

Q: Is the 5611201080F RoHS compliant?

A: Yes. The 5611201080F meets ROHS3 compliance standards, whereas the original part is RoHS non-compliant. This represents an improvement for regulatory requirements.

Q: Can I use 5611201080F in existing designs without circuit modifications?

A: Electrical substitution is direct with no circuit changes required. Mechanical integration requires PCB layout review to accommodate the larger 5mm lens diameter and verify mounting hole compatibility.
