Dialight 5500804 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5500804 is a 5mm through-hole LED circuit board indicator featuring a single yellow diffused lens with a domed top. Designed for 5V applications at 10mA current draw, this component delivers 8 millicandela brightness with a 60-degree viewing angle. The part is classified as obsolete, making identification of active equivalent models essential for ongoing production and maintenance applications. The 5500804F serves as the direct active substitute, maintaining identical electrical and mechanical specifications while offering current availability.

Key Parameters

Substitute Part Grouping Explanation

The 5500804F qualifies as a direct substitute for the 5500804 based on complete alignment across all critical electrical and mechanical parameters. Substitution criteria are determined by the following parameters:

• Lens size and style (5mm, T-1 3/4, round with domed top)
• Color and wavelength (yellow, 583nm peak)
• Electrical specifications (5V rating, 10mA current, 8mcd brightness)
• Viewing angle (60 degrees)
• Mounting configuration (through-hole)
• Lens type (diffused)

The 5500804F maintains identical specifications across all these parameters, enabling direct replacement in circuit board designs originally specified for the 5500804.

Parameter Comparison

Engineering Selection Recommendations

The 5500804F is the appropriate selection for applications currently using or specifying the obsolete 5500804. As an active product from the same manufacturer and series, the 5500804F provides continuity of supply while maintaining full electrical and mechanical compatibility. The 5500804F carries ROHS3 compliance certification, meeting current environmental regulatory requirements. Both parts share identical REACH and ECCN classifications, ensuring regulatory consistency in procurement and deployment.

Frequently Asked Questions (FAQ)

Q: Can the 5500804F directly replace the 5500804 in existing designs? A: Yes. The 5500804F maintains identical electrical specifications (5V, 10mA), brightness output (8mcd), color (yellow, 583nm), viewing angle (60 degrees), and mechanical form factor (5mm through-hole with domed diffused lens). No circuit modifications are required.

Q: What is the primary difference between these parts? A: The 5500804 is obsolete, while the 5500804F is an active product. The 5500804F also carries ROHS3 compliance certification. All functional and electrical parameters remain identical.

Q: Are there packaging differences between the two parts? A: The 5500804 is specified with standard packaging, while the 5500804F is supplied in bulk packaging. This distinction affects procurement and handling but does not impact component performance or compatibility.

Q: Do these parts share the same moisture sensitivity level? A: Yes. Both the 5500804 and 5500804F carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity constraints during storage or handling.

Q: Are regulatory certifications identical? A: Both parts share REACH Unaffected and EAR99 ECCN classifications. The 5500804F additionally carries ROHS3 compliance, which is advantageous for current regulatory environments.
