Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Dialight 5510201010F are qualified based on matching the following critical parameters: lens size (3mm, T-1), color (green), peak wavelength (565nm), voltage rating (2.1V), current rating (20mA), lens type (diffused, tinted), lens style (round with domed top), mounting type (through hole, right angle), and configuration (single). All identified substitutes maintain ROHS3 compliance and MSL rating of 1. Variations in millicandela rating and viewing angle are permitted within the substitute group, as these parameters do not affect mechanical or primary electrical compatibility in circuit board indicator applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance, qualifying them for current production use. The Dialight 5510201F provides direct manufacturer equivalence to the primary part number 5510201010F, with identical electrical and optical specifications. The Lumex SSF-LXH103LGD offers cross-manufacturer substitution with higher millicandela output (15mcd versus 12.6mcd) and wider viewing angle (80° versus 60°), while maintaining all critical electrical parameters and compliance certifications. Selection between these options depends on inventory availability, supply chain requirements, and application-specific brightness and viewing angle needs.

Frequently Asked Questions (FAQ)

Q: Can Dialight 5510201F be used as a direct replacement for Dialight 5510201010F? A: Yes. Both parts share identical electrical specifications (2.1V, 20mA), optical characteristics (565nm, 12.6mcd, 60° viewing angle), and mechanical form factor (3mm T-1 through-hole right-angle mount). They are functionally equivalent.

Q: What are the differences between the Dialight and Lumex options? A: The Lumex SSF-LXH103LGD maintains all critical electrical and mechanical parameters but provides higher brightness (15mcd versus 12.6mcd) and wider viewing angle (80° versus 60°). These differences do not affect circuit compatibility but may impact visual performance in the application.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All three parts carry ROHS3 compliance certification and MSL rating of 1 (unlimited moisture sensitivity level), meeting current regulatory requirements.

Q: Can these parts be used interchangeably on the same PCB? A: Yes. All parts share identical mounting type (through-hole right-angle), lens size (3mm T-1), and electrical ratings (2.1V, 20mA), enabling direct PCB footprint compatibility.

Q: What should be considered when selecting between these substitutes? A: Primary considerations are supply chain availability, cost, and application-specific requirements for brightness and viewing angle. The Lumex part offers higher brightness and wider viewing angle, while the Dialight 5510201F provides exact specification matching to the primary part.
