Dialight 5505207 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5505207 is a 5mm green LED circuit board indicator designed for through-hole, right-angle mounting applications. This component features a diffused lens with domed top, rated for 2.2V at 20mA operation, and delivers 34 millicandela at a 50° viewing angle. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing production and maintenance applications. Active equivalent parts are available from both Dialight and Lumex Opto/Components Inc. that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Dialight 5505207 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Electrical Parameters: Voltage rating (2.2V), current rating (20mA), and wavelength peak (565nm ±tolerance) establish electrical interchangeability.

Optical Parameters: Color (green), lens type (diffused), and lens style (round with domed top) define visual performance characteristics.

Mechanical Parameters: Lens size (5mm), mounting type (through hole, right angle), and package form factor ensure physical compatibility with existing PCB layouts.

Regulatory Parameters: RoHS compliance status and REACH classification confirm environmental and regulatory alignment.

The substitute parts listed maintain these core parameters within acceptable engineering tolerances, enabling direct replacement in circuit board indicator applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute - Dialight 5505207F: This part maintains identical electrical specifications (2.2V, 20mA) and optical output (34mcd, 50° viewing angle) to the original 5505207. The 5505207F carries active product status and ROHS3 compliance, providing regulatory alignment for new designs and production continuity. Wavelength peak variance (563nm vs. 565nm) falls within acceptable green LED manufacturing tolerances.

Secondary Substitutes - Lumex SSF-LXH100LGD-01 and SSF-LXH100MGD: Both Lumex parts maintain core electrical compatibility (2.2V, 20mA) and mechanical form factor (5mm through-hole, right-angle mount). These components feature expanded viewing angles (60° vs. 50°) and tinted diffused lenses. The SSF-LXH100LGD-01 delivers 30mcd output, while the SSF-LXH100MGD delivers 20mcd. Both carry active product status and ROHS3 compliance. Selection between these Lumex alternatives depends on brightness requirements for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the Dialight 5505207F directly replace the obsolete 5505207?

A: Yes. The 5505207F maintains identical voltage (2.2V), current (20mA), brightness (34mcd), and viewing angle (50°) specifications. Mechanical compatibility is confirmed through matching through-hole, right-angle mounting and 5mm lens form factor. The primary difference is active product status and ROHS3 compliance certification.

Q: What are the key differences between Dialight and Lumex substitute options?

A: The Dialight 5505207F preserves the original 50° viewing angle and 34mcd brightness. Lumex alternatives (SSF-LXH100LGD-01 and SSF-LXH100MGD) offer wider 60° viewing angles but reduced brightness ratings (30mcd and 20mcd respectively). All three maintain 2.2V/20mA electrical specifications and through-hole, right-angle mounting compatibility.

Q: Are there brightness differences between the Lumex SSF-LXH100LGD-01 and SSF-LXH100MGD?

A: Yes. The SSF-LXH100LGD-01 delivers 30mcd while the SSF-LXH100MGD delivers 20mcd. Both feature identical electrical ratings (2.2V, 20mA), expanded 60° viewing angles, and tinted diffused lenses. Selection should be based on the minimum brightness requirement for the target application.

Q: Do all substitute parts meet current regulatory requirements?

A: The Dialight 5505207F and both Lumex parts (SSF-LXH100LGD-01 and SSF-LXH100MGD) carry ROHS3 compliance certification. All parts maintain MSL 1 (Unlimited) moisture sensitivity ratings and REACH Unaffected status, confirming environmental and regulatory alignment.

Q: What is the significance of the T-1 3/4 lens size designation on Lumex parts?

A: T-1 3/4 is a standard LED package designation equivalent to 5mm diameter. This confirms mechanical compatibility with the original 5505207 through-hole PCB footprint and mounting requirements.
