Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5611R5 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Color: Green (565nm wavelength)
• Configuration: Single LED
• Mounting Type: Through Hole
• Voltage Rating: 2.3V nominal
• Current Rating: 20mA nominal
• Lens Type: Diffused optical characteristics
• RoHS3 Compliance
• MSL Rating: 1 (Unlimited)

Secondary Consideration:

• Lens geometry and size variations are permissible when mechanical envelope constraints allow

The substitute parts identified maintain electrical compatibility through matching voltage and current specifications, optical consistency via green wavelength output, and regulatory alignment through ROHS3 compliance and MSL ratings.

Parameter Comparison

Engineering Selection Recommendations

5614201081F (Dialight) provides the closest electrical and optical substitution for the 5611R5. This part maintains identical voltage rating (2.3V), current rating (20mA), wavelength (565nm), and mounting configuration (Through Hole). The lens geometry remains rectangular with flat top, with dimensions of 7.00mm x 2.50mm, representing minimal deviation from the original 7.30mm x 2.40mm specification. The 5614201081F carries Active product status, ensuring long-term availability and supply chain continuity. Full ROHS3 compliance and MSL 1 rating align with the original component specifications.

6321F5 (VCC) presents an alternative with electrical and optical compatibility constraints. While maintaining green wavelength output and ROHS3 compliance, this part operates at reduced current (10mA versus 20mA) and lower voltage (2.1V versus 2.3V). The lens configuration differs substantially, featuring a 3mm round domed-top design rather than the rectangular flat-top geometry. This substitute is suitable only when circuit design accommodates the reduced current specification and mechanical envelope permits the smaller, round lens form factor. The 6321F5 remains classified as obsolete.

Both substitute parts satisfy regulatory requirements through ROHS3 compliance, REACH unaffected status, and MSL 1 ratings matching the original component.

Frequently Asked Questions (FAQ)

Q: Can the 5614201081F directly replace the 5611R5 in existing designs?

A: The 5614201081F maintains electrical compatibility through matching 2.3V voltage and 20mA current specifications. The rectangular flat-top lens geometry aligns with the original design intent. Lens dimensions vary slightly (7.00mm x 2.50mm versus 7.30mm x 2.40mm), requiring verification that mechanical envelope constraints are satisfied in the specific application.

Q: What are the key differences between the 5614201081F and 6321F5 substitutes?

A: The 5614201081F operates at 20mA and 2.3V with rectangular lens geometry, matching the original 5611R5 electrical specifications. The 6321F5 operates at reduced current (10mA) and voltage (2.1V) with a 3mm round domed-top lens. Selection depends on circuit design requirements and available mechanical space.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. Both the 5614201081F and 6321F5 carry ROHS3 compliance certification, matching the original 5611R5 specification. All parts are REACH unaffected and carry MSL 1 (Unlimited) ratings.

Q: What is the significance of the 5614201081F being Active status versus the 5611R5 being Obsolete?

A: Active product status indicates the 5614201081F remains in current production with established supply chain support. This ensures component availability for new procurement and long-term design support, addressing the obsolescence constraint of the original 5611R5.

Q: How do millicandela ratings affect substitution decisions?

A: The 5611R5 delivers 7mcd output. The 5614201081F delivers 2.5mcd, while the 6321F5 delivers 8.5mcd. Brightness differences require circuit-level evaluation to confirm adequate indicator visibility in the target application environment.

Q: Are there viewing angle differences between these parts?

A: The 5614201081F specifies a 100° viewing angle. The 5611R5 and 6321F5 do not provide viewing angle specifications in the available data. Application requirements for viewing angle coverage should be evaluated against the 5614201081F specification.
