Substitute Part Grouping Explanation

Substitute parts for the Dialight 5510307010F are classified into two categories based on parameter alignment:

Direct Substitutes (Dialight Series 551): Parts 5510307F and 5510311F maintain identical electrical specifications including 2.1V voltage rating, 10mA current, 6.3mcd luminous intensity, 585nm peak wavelength, and 45° viewing angle. Mechanical parameters including 3mm T-1 lens size, round domed top lens style, diffused tinted lens type, and through-hole right-angle mounting are fully matched. These parts are interchangeable at the circuit board level without parameter deviation.

Compatible Substitute (Alternative Manufacturer): Part H100CYDL from Bivar Inc. operates at a lower voltage rating (1.9V versus 2.1V) and reduced luminous intensity (4mcd versus 6.3mcd). Current rating is not specified for this part. The 585nm peak wavelength, yellow color, 45° viewing angle, 3mm T-1 lens size, round domed top style, diffused lens type, and through-hole right-angle mounting are preserved. This part functions as a compatible alternative where voltage and brightness parameters are acceptable within circuit design tolerances.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: Parts 5510307F and 5510311F are suitable for direct substitution in applications requiring the Dialight 5510307010F. Both maintain identical voltage, current, and luminous intensity specifications. All three Dialight parts carry Active product status and ROHS3 compliance, ensuring regulatory alignment and supply chain continuity.

For Alternative Manufacturer Selection: The Bivar Inc. H100CYDL presents a compatible alternative where circuit design accommodates a 0.2V lower operating voltage (1.9V versus 2.1V) and 2.3mcd reduced luminous intensity (4mcd versus 6.3mcd). This part is appropriate for applications where brightness reduction is acceptable and voltage tolerance exists within the design margin. The H100CYDL maintains ROHS3 compliance and Active product status.

Compliance Considerations: All substitute parts listed maintain ROHS3 compliance and MSL 1 rating, eliminating compliance risk in substitution decisions. Selection should be based on electrical parameter tolerance within the specific circuit application.

Frequently Asked Questions (FAQ)

Q: Can 5510307F and 5510311F be used interchangeably with 5510307010F? A: Yes. Both parts maintain identical electrical parameters (2.1V, 10mA, 6.3mcd) and mechanical specifications (3mm T-1 through-hole right-angle mount, diffused tinted lens, round domed top). Direct substitution is supported without circuit modification.

Q: What are the key differences between Dialight and Bivar substitutes? A: Dialight parts 5510307F and 5510311F are electrically identical to the main part. The Bivar H100CYDL operates at 1.9V (0.2V lower) and produces 4mcd (2.3mcd lower) compared to 6.3mcd. Mechanical form factors remain consistent across all parts.

Q: Is the H100CYDL suitable for my application? A: The H100CYDL is compatible if your circuit design tolerates 1.9V operation and reduced brightness output. Verify that the lower voltage and luminous intensity do not compromise indicator visibility or circuit function before implementation.

Q: Are there packaging differences between substitute parts? A: The main part and Dialight substitutes are supplied in Bulk packaging. The Bivar H100CYDL is supplied in Tray packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: Do all substitute parts meet RoHS compliance? A: Yes. All listed parts including 5510307F, 5510311F, and H100CYDL maintain ROHS3 compliance. MSL 1 (Unlimited) rating applies to all parts, eliminating moisture sensitivity concerns in storage and handling.

Q: What is the viewing angle specification across all parts? A: The main part 5510307010F specifies 45° viewing angle. Both Dialight substitutes (5510307F, 5510311F) maintain 45° viewing angle. The Bivar H100CYDL also provides 45° viewing angle, ensuring consistent light distribution characteristics.
