Substitute Part Grouping Explanation

Substitution of the obsolete Dialight 5580201808 is based on strict electrical and mechanical parameter matching within the Dialight 558 series. All substitute parts maintain identical electrical ratings (2.1V forward voltage, 25mA maximum current), optical characteristics (green diffused lens, 563nm peak wavelength, 40° viewing angle, 16mcd brightness), and mechanical form factors (3mm T-1 lens, round domed top, 0.16" panel cutout).

The substitute parts are grouped into two categories:

Direct Manufacturer Substitute (Active Status): Part 5580201808F provides a direct replacement with snap-in termination style and active product status, offering improved RoHS3 compliance compared to the obsolete original.

Parametric Equivalents (Active Status): Parts 5580201805F, 5580201809F, 5580201810F, 5580201811F, 5580201812F, 5580201814F, 5580201815F, and 5580201816F are parametric equivalents sharing all critical electrical and optical specifications. These parts differ only in internal construction details or lead configurations not affecting functional performance in standard panel-mount applications.

Engineering Selection Recommendations

All substitute parts listed are functionally equivalent to the Dialight 5580201808 based on matching electrical ratings, optical characteristics, and mechanical specifications. The primary distinction between options is product status and regulatory compliance.

The obsolete 5580201808 is non-compliant with RoHS regulations. All active substitute parts (5580201808F, 5580201805F, 5580201809F, 5580201810F, 5580201811F, 5580201812F, 5580201814F, 5580201815F, 5580201816F) are ROHS3 compliant and carry active product status from Dialight, ensuring continued availability and support.

For new designs and production applications, selection should prioritize parts with the highest inventory availability to ensure supply continuity. Part 5580201815F offers 1188 pieces in stock, followed by 5580201805F with 1142 pieces. All substitute parts maintain identical REACH unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can the obsolete 5580201808 be directly replaced with any of the listed substitutes?

A: Yes. All listed substitute parts maintain identical electrical ratings (2.1V, 25mA), optical specifications (green diffused, 563nm, 40° viewing angle, 16mcd), and mechanical form factors (3mm T-1, 0.16" panel cutout). Direct functional substitution is supported without circuit modification.

Q: What is the difference between the direct substitute 5580201808F and the parametric equivalents?

A: The 5580201808F is the direct manufacturer replacement with snap-in termination. The parametric equivalents (5580201805F through 5580201816F) share all critical electrical and optical performance but may differ in internal LED die configuration or lead material. All are functionally interchangeable in standard panel-mount applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. All active substitute parts carry ROHS3 compliance certification. The original 5580201808 is RoHS non-compliant. Substitution with any listed part upgrades regulatory compliance for new production.

Q: Do the substitute parts have different packaging options?

A: All substitute parts are supplied in bulk packaging. The original 5580201808 packaging specification was not provided. Confirm packaging requirements with your procurement department if specific packaging formats are required.

Q: Is there any difference in brightness or color between the original and substitutes?

A: No. All parts maintain identical millicandela rating (16mcd), peak wavelength (563nm), lens color (green), and lens transparency (diffused). Optical performance is equivalent across all parts.

Q: Which substitute part should be selected for maximum supply availability?

A: Part 5580201815F provides the highest inventory level at 1188 pieces in stock, followed by 5580201805F at 1142 pieces. Both are active products with ROHS3 compliance.
