Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5912501102F is determined by the following critical parameters:

• Color and Wavelength: Orange at 610nm peak wavelength
• Voltage Rating: 2V nominal operation
• Configuration: Single LED element
• Mounting Type: Surface Mount, Right Angle orientation
• Lens Style: Round with Domed Top
• Viewing Angle: 40° minimum
• Compliance: ROHS3 Compliant, REACH Unaffected

The substitute part 5912501102NF shares the same manufacturer (Dialight), series (591), color, wavelength, voltage rating, configuration, mounting type, lens style, viewing angle, and compliance certifications. Variations in lens diameter (2.85mm vs. 3mm), current rating (20mA vs. 10mA), and brightness (83mcd vs. 8mcd) represent the primary technical differences within the substitution group.

Parameter Comparison

Engineering Selection Recommendations

The 5912501102NF is an active production substitute for the obsolete 5912501102F. Both components maintain identical compliance certifications (ROHS3 Compliant, REACH Unaffected) and share the same voltage rating, color specification, wavelength, configuration, mounting type, and viewing angle.

The substitute part operates at double the current rating (20mA vs. 10mA) and delivers significantly higher brightness output (83mcd vs. 8mcd). The lens diameter is marginally smaller (2.85mm vs. 3mm). These differences must be evaluated against specific circuit design requirements, PCB layout constraints, and optical performance specifications of the target application.

Frequently Asked Questions (FAQ)

Q: Can the 5912501102NF directly replace the 5912501102F in existing designs?

A: Direct substitution requires verification of three factors: (1) circuit current-limiting design compatibility with the 20mA rating, (2) PCB layout accommodation of the 2.85mm lens diameter versus the original 3mm specification, and (3) optical performance acceptance of the increased 83mcd brightness output.

Q: Are there compliance or regulatory differences between these parts?

A: No. Both parts carry identical ROHS3 Compliant and REACH Unaffected certifications with matching MSL ratings of 2 (1 Year).

Q: What is the primary technical difference between these substitute parts?

A: The 5912501102NF operates at 20mA with 83mcd output brightness, compared to the 5912501102F at 10mA with 8mcd output. The lens diameter is also reduced from 3mm to 2.85mm.

Q: Why is the original part classified as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 5912501102NF represents the active production equivalent within the Dialight 591 series.

Q: Are packaging differences significant for procurement?

A: The substitute part is supplied in Strip packaging. Packaging format may affect handling, storage, and assembly process integration requirements.
