Engineering Selection Recommendations

All listed substitute parts are direct parametric equivalents of the obsolete 5580201809. Selection among the active alternatives should be based on the following factors:

Product Status: All substitute parts carry active production status, ensuring long-term availability and supply chain stability compared to the obsolete original.

Regulatory Compliance: All substitute parts are ROHS3 compliant, meeting current environmental and regulatory requirements. The original 5580201809 is RoHS non-compliant and should be replaced in new designs or production runs subject to RoHS directives.

Inventory Availability: Part 5580201815F offers the highest inventory level at 1188 pieces, followed by 5580201805F at 1142 pieces. These options provide optimal supply security for high-volume applications.

Certification Status: All substitute parts maintain identical REACH unaffected status and EAR99 ECCN classification as the original component.

Frequently Asked Questions (FAQ)

Q: Can I directly substitute any of these parts for the obsolete 5580201809?

A: Yes. All listed substitute parts are parametrically equivalent across electrical ratings (2.1V, 25mA), optical characteristics (green diffused lens, 40° viewing angle, 16mcd), mechanical dimensions (3mm T-1 lens, 0.16" panel cutout), and wavelength specification (563nm). Direct substitution is supported without circuit modification.

Q: What is the difference between the substitute part numbers?

A: The substitute parts share identical electrical and optical specifications. Differences exist only in internal manufacturing variants or packaging configurations within the Dialight 558 series. All are functionally equivalent for panel indicator applications.

Q: Why should I transition from the obsolete 5580201809?

A: The original part is obsolete and RoHS non-compliant. Active production alternatives ensure continued supply availability, compliance with current environmental regulations (ROHS3), and support for long-term product lifecycle management.

Q: Are there any compatibility concerns with panel cutout dimensions?

A: No. All substitute parts maintain the identical round panel cutout specification of 0.16" (4.06mm), ensuring mechanical compatibility with existing panel designs and mounting hardware.

Q: Do these parts have the same moisture sensitivity rating?

A: Yes. All parts, including the original and all substitutes, carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
