Key Parameters

Substitute Part Grouping Explanation

The Dialight 5505205F qualifies as a direct substitute based on the following critical parameters that determine functional equivalence:

• Color and Wavelength: Both parts emit green light at comparable peak wavelengths (565nm vs. 563nm), ensuring consistent optical performance in indicator applications.
• Electrical Specifications: Identical voltage rating (2.2V) and current rating (20mA) allow direct circuit integration without modification.
• Brightness Output: Both parts deliver 34mcd, maintaining consistent luminous intensity in the application.
• Optical Characteristics: Matching lens type (diffused, tinted), lens style (round with domed top), and viewing angle (50°) preserve the visual appearance and light distribution pattern.
• Mounting Configuration: Both parts feature through-hole, right-angle mounting, ensuring mechanical compatibility with existing PCB layouts.
• Environmental Compliance: Identical REACH status (REACH Unaffected), ECCN (EAR99), and HTSUS classification (8541.41.0000) confirm regulatory equivalence.
• Moisture Sensitivity: Both parts carry MSL 1 (Unlimited), indicating identical environmental handling requirements.

The primary distinction is product status: the 5505205F is active and currently in production, whereas the 5505205 is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5505205F is the appropriate selection for new designs and production continuity. The 5505205 is obsolete and should be replaced in active applications. The 5505205F maintains full electrical, optical, and mechanical compatibility while offering the advantage of active production status and ROHS3 compliance certification. Both parts satisfy identical regulatory requirements under REACH and export control classifications.

Frequently Asked Questions (FAQ)

Q: Can the 5505205F directly replace the 5505205 in existing circuit designs?

A: Yes. The 5505205F provides direct functional equivalence across all critical parameters: identical voltage rating (2.2V), current rating (20mA), brightness output (34mcd), lens configuration, mounting type, and viewing angle (50°). No circuit modifications are required.

Q: What is the significance of the wavelength difference between 565nm and 563nm?

A: Both wavelengths fall within the green spectrum and are visually indistinguishable in indicator applications. The 2nm difference is within normal manufacturing tolerance for LED components and does not affect functional performance in circuit board indicator applications.

Q: Are there packaging differences between these parts?

A: The 5505205 packaging is listed as unspecified, while the 5505205F is supplied in bulk packaging. Both parts use identical through-hole, right-angle mounting configurations suitable for PCB assembly.

Q: Does the 5505205F offer any compliance advantages?

A: The 5505205F carries ROHS3 compliance certification, whereas the 5505205 compliance status is not specified. Both parts maintain identical REACH status (REACH Unaffected) and export control classification (EAR99).

Q: What is the inventory status for these parts?

A: The 5505205 (obsolete) has 826 pieces in stock. The 5505205F (active) has 2,184 pieces in stock, reflecting its current production status.
