Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5912401013F is based on the following critical parameters that must remain consistent:

• Manufacturer: Dialight (same product family)
• Series: 591 (same series designation)
• Color: Yellow (same optical output color)
• Configuration: Single (same LED configuration)
• Current Rating: 20mA (same electrical requirement)
• Voltage Rating: 2V (same operating voltage)
• Mounting Type: Surface Mount, Right Angle (same PCB interface)
• Lens Style: Round with Domed Top (same optical geometry)
• RoHS and REACH Compliance: Maintained across substitutes

The substitute part 5912401013NF shares all critical parameters with the main part. Variations in lens size (2.85mm vs. 3mm), wavelength peak (591nm vs. 586nm), and millicandela rating (71mcd vs. 5.7mcd) reflect manufacturing improvements within the same product family while maintaining functional compatibility for circuit board indicator applications.

Parameter Comparison

Engineering Selection Recommendations

The 5912401013NF is the designated substitute for the obsolete 5912401013F. Both components maintain identical electrical specifications (2V, 20mA), mounting configuration (Surface Mount, Right Angle), and regulatory compliance (ROHS3, REACH Unaffected). The substitute part is currently in Active product status with higher inventory availability, ensuring procurement continuity.

The 5912401013NF features improved luminous intensity (71mcd vs. 5.7mcd) and a slightly reduced lens diameter (2.85mm vs. 3mm), representing a design evolution within the 591 series. These differences do not affect electrical compatibility or circuit board interface requirements. The substitute part is available in Tape & Reel packaging, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 5912401013NF directly replace the 5912401013F in existing designs?

A: Yes. Both parts share identical voltage (2V), current (20mA), mounting type (Surface Mount, Right Angle), and lens style (Round with Domed Top). The electrical interface and PCB footprint remain compatible.

Q: What is the significance of the lens size difference (3mm vs. 2.85mm)?

A: The 2.85mm lens on the substitute part represents a minor dimensional variation within the same product family. This difference may affect visual appearance and light distribution characteristics but does not impact electrical functionality or circuit compatibility.

Q: Why does the substitute part have higher millicandela rating (71mcd vs. 5.7mcd)?

A: The increased luminous intensity reflects manufacturing improvements in the 591 series. The substitute part delivers brighter light output while maintaining the same 40° viewing angle and 2V/20mA electrical specifications.

Q: Are there packaging considerations when switching to the 5912401013NF?

A: The main part is supplied in bulk packaging, while the substitute is available in Tape & Reel (TR) format. Tape & Reel packaging is optimized for automated pick-and-place assembly and offers improved handling for high-volume production.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the 5912401013F and 5912401013NF are ROHS3 Compliant and REACH Unaffected, with identical MSL ratings (2, 1 Year). Regulatory compliance is maintained across the substitution.

Q: What is the wavelength difference between the two parts?

A: The main part has a peak wavelength of 586nm, while the substitute is 591nm. Both fall within the yellow spectrum and are visually indistinguishable for circuit board indicator applications.
