Dialight 5580501003 LED Panel Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5580501003 is a green LED panel indicator with snap-in mounting, designed for 2.1V operation at 30mA maximum current. This component features a 3mm T-1 lens with clear domed top, 565nm peak wavelength, and 45° viewing angle. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications requiring compatible green LED panel indicators with identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution for the Dialight 5580501003 is determined by strict equivalence across all electrical and mechanical parameters. The allowed substitution criteria are:

Identical lamp color (Green)
Identical peak wavelength (565nm)
Identical forward voltage (2.1V)
Identical maximum current (30mA)
Identical lens size and style (3mm T-1, round with domed top)
Identical lens color and transparency (colorless, clear)
Identical millicandela rating (70mcd)
Identical viewing angle (45°)
Identical panel cutout shape and dimensions (round, 0.16"/4.06mm)
Identical termination style (wire leads, 6"/152.40mm)
Identical series designation (558)

The substitute parts 5580501003F and 5580501023F meet all these criteria and are therefore direct parametric equivalents suitable for replacement in applications requiring the 5580501003.

Engineering Selection Recommendations

Both 5580501003F and 5580501023F are active production parts that provide direct parametric equivalence to the obsolete 5580501003. Selection between these two substitutes should be based on the following factors:

The 5580501003F maintains the original part number base (5580501) with an "F" suffix, indicating a direct evolution of the discontinued part with ROHS3 compliance achieved through standard manufacturing updates.

The 5580501023F carries the same base number with a "23F" suffix and includes PVC-free construction in addition to ROHS3 compliance, offering enhanced environmental compliance for applications with stricter material restrictions.

Both parts are ROHS3 compliant and REACH unaffected, addressing regulatory requirements that the original obsolete part did not meet. The choice between them depends on whether PVC-free construction is a requirement for the application.

Frequently Asked Questions (FAQ)

Q: Can 5580501003F and 5580501023F be used interchangeably with the original 5580501003?

A: Yes. Both substitute parts are parametric equivalents with identical electrical ratings (2.1V, 30mA), optical characteristics (565nm green, 70mcd, 45° viewing angle), and mechanical specifications (3mm T-1 lens, round 0.16" panel cutout, 6" wire leads). They are direct replacements for the obsolete part.

Q: What is the difference between 5580501003F and 5580501023F?

A: Both parts meet identical electrical and optical specifications. The primary difference is that 5580501023F includes PVC-free construction. Both are ROHS3 compliant and suitable for replacement applications.

Q: Why is the original 5580501003 listed as obsolete?

A: The original part is RoHS non-compliant. The substitute parts 5580501003F and 5580501023F are active production alternatives that meet current ROHS3 compliance requirements while maintaining full parametric equivalence.

Q: Are there any packaging differences between these parts?

A: The original 5580501003 was packaged in standard format. Both substitute parts are available in bulk packaging, which is typical for active production components.

Q: Will these substitutes work in existing circuit designs without modification?

A: Yes. The electrical parameters (2.1V forward voltage, 30mA maximum current) and mechanical specifications (panel cutout dimensions, wire lead length) are identical, requiring no circuit or mechanical design changes.

Q: What certifications apply to the substitute parts?

A: Both 5580501003F and 5580501023F are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.41.0000, matching the regulatory classification of the original part.
