Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5988010100F is determined by the following critical parameters:

• Wavelength - Dominant: 635nm (Red) - must match exactly
• Package / Case: 0603 (1608 Metric) - must match for PCB compatibility
• Mounting Type: Surface Mount - must match for assembly process
• Lens Color and Transparency: Colorless / Clear - must match for optical consistency
• Lens Style: Rectangle with Flat Top - must match for mechanical fit
• Viewing Angle: 140° - must match for application requirements
• Size / Dimension and Height: 1.60mm L x 0.80mm W, 0.70mm max height - must match for board layout
• Current - Test: 20mA - must match for circuit design parameters

The substitute part 5988010107F meets all these critical parameters. Variations in forward voltage (Vf) and millicandela rating are within acceptable tolerance for this LED category when the above parameters are matched.

Parameter Comparison

Engineering Selection Recommendations

Both the Dialight 5988010100F and 5988010107F are Active status components with ROHS3 compliance and REACH unaffected status, qualifying them for current production use. The parts share identical mechanical and optical specifications, including package format, mounting type, lens configuration, and viewing angle.

The primary differences are forward voltage (2.2V vs 2V) and brightness rating (40mcd vs 60mcd). The substitute part 5988010107F provides higher luminous intensity at lower forward voltage, making it suitable for applications where increased brightness or reduced power consumption is beneficial. The MSL rating difference (2 vs 3) reflects different moisture sensitivity classifications and should be considered based on storage and assembly environment conditions.

Selection between these parts depends on circuit design requirements for forward voltage and desired brightness output. Both parts maintain identical form factor and electrical test current specifications.

Frequently Asked Questions (FAQ)

Q: Can 5988010107F replace 5988010100F in existing designs?

A: Yes, provided the circuit design accommodates the lower forward voltage (2V vs 2.2V) and higher brightness output (60mcd vs 40mcd). The mechanical and optical specifications are identical, ensuring PCB compatibility and assembly process compatibility.

Q: Are there differences in package format between these parts?

A: Both parts use the 0603 (1608 Metric) package with identical dimensions (1.60mm L x 0.80mm W, 0.70mm max height). The packaging format differs (Strip vs Cut Tape & Digi-Reel®), which affects supply and handling but not component performance or PCB mounting.

Q: What is the significance of the MSL rating difference?

A: MSL 2 (1 Year) indicates the main part can be stored for up to one year at specified humidity levels before requiring baking. MSL 3 (168 Hours) indicates the substitute part has a shorter shelf life of 168 hours under the same conditions. Storage and assembly environment conditions should determine which MSL rating is acceptable for your manufacturing process.

Q: Do both parts meet current compliance requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both carry the same HTSUS code (8541.41.0000) for tariff classification.

Q: What is the optical difference between these LEDs?

A: Both parts feature identical lens specifications: colorless, clear transparency, rectangle with flat top style, 1.10mm x 0.80mm lens size, and 140° viewing angle. The difference is brightness output: 5988010100F provides 40mcd while 5988010107F provides 60mcd at the same 20mA test current.
