Dialight 5552003 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5552003 is a single red LED circuit board indicator designed for 5V applications with 6mA current consumption. This component features a 2.00mm diameter round lens with domed top, mounted through-hole in a right-angle configuration, and delivers 1.9 millicandela brightness at 650nm peak wavelength with a 40° viewing angle.

The 5552003 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or maintenance requirements for legacy systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5552003 LED circuit board indicator is determined by strict equivalence across the following critical parameters:

• Color specification (Red)
• Peak wavelength (650nm)
• Current rating (6mA)
• Millicandela output (1.9mcd)
• Viewing angle (40°)
• Lens configuration (Clear, Round with Domed Top, 2.00mm Dia)
• Voltage rating (5V)
• Mounting type (Through Hole, Right Angle)
• Configuration (Single)

The substitute part 5552003F maintains identical electrical and mechanical specifications across all these parameters, ensuring direct functional equivalence within the 555 series product line.

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5552003F serves as the direct active-production substitute for the obsolete 5552003. Both components maintain identical electrical performance and mechanical form factor across all specified parameters.

The 5552003F offers the additional advantage of ROHS3 compliance, whereas the original 5552003 is RoHS non-compliant. For applications subject to RoHS regulatory requirements or environmental compliance mandates, the 5552003F is the appropriate selection. Both parts maintain equivalent moisture sensitivity classification and REACH status.

Inventory availability differs between the two parts: the obsolete 5552003 has limited stock (678 pcs), while the active 5552003F maintains higher availability (3304 pcs). For new designs or ongoing production requirements, the 5552003F is the recommended selection based on product status and supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the 5552003F directly replace the 5552003 in existing designs?

A: Yes. The 5552003F maintains identical electrical specifications (5V, 6mA, 1.9mcd at 650nm), optical characteristics (40° viewing angle, clear round domed lens, 2.00mm diameter), and mechanical mounting (through-hole, right-angle configuration). Direct substitution is supported without circuit modification.

Q: What is the difference between the 5552003 and 5552003F?

A: The primary differences are product status and RoHS compliance. The 5552003 is obsolete and RoHS non-compliant, while the 5552003F is an active product with ROHS3 compliance. All functional and mechanical parameters are identical.

Q: Are there packaging differences between these parts?

A: The 5552003 is supplied in standard packaging, while the 5552003F is supplied in bulk packaging. Both maintain the same component specifications and performance characteristics.

Q: Which part should be selected for new designs?

A: The 5552003F should be selected for new designs. It is an active product with current manufacturing support, higher inventory availability, and ROHS3 compliance status.

Q: Is the 5552003F suitable for RoHS-regulated applications?

A: Yes. The 5552003F carries ROHS3 compliance certification, making it suitable for applications subject to RoHS directives and environmental regulations.
