Dialight 5505204 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5505204 is a through-hole mounted LED circuit board indicator featuring a single green diffused lens with a domed top. This component is designed for applications requiring a 5.00mm diameter indicator light with a 2.2V forward voltage and 20mA operating current. The part is currently classified as obsolete, making identification of suitable substitutes essential for ongoing production and maintenance applications. The active equivalent 5505204F provides functional continuity while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

The Dialight 5505204F qualifies as a direct substitute based on the following critical parameters:

Electrical Compatibility:

• Identical forward voltage rating (2.2V)
• Identical current rating (20mA)
• Identical millicandela output (34mcd)
• Identical viewing angle (50°)

Optical Compatibility:

• Identical color (Green)
• Identical lens type (Diffused, Tinted)
• Identical lens style (Round with Domed Top)
• Peak wavelength within acceptable tolerance (563nm vs 565nm)

Mechanical Compatibility:

• Identical mounting type (Through Hole)
• Equivalent lens size (5mm, T-1 3/4 vs 5.00mm Dia)
• Identical MSL rating (1 - Unlimited)

Regulatory Compliance:

• Identical REACH status (REACH Unaffected)
• Identical ECCN classification (EAR99)
• Identical HTSUS code (8541.41.0000)

The 5505204F maintains the same series designation (550) and represents the active production equivalent of the obsolete 5505204.

Engineering Selection Recommendations

The Dialight 5505204F is the direct substitute for the obsolete 5505204. Selection of the 5505204F is supported by the following factors:

Product Status: The 5505204 is classified as obsolete, while the 5505204F maintains active production status. This ensures long-term availability and supply chain continuity.

Regulatory Compliance: The 5505204F carries ROHS3 compliance certification, providing enhanced environmental compliance compared to the main part. Both parts maintain identical REACH and ECCN classifications.

Electrical and Optical Performance: All critical electrical parameters (voltage, current, luminous intensity) and optical characteristics (color, wavelength, viewing angle, lens properties) are identical or within acceptable tolerance.

Mechanical Compatibility: Through-hole mounting configuration and lens dimensions are equivalent, ensuring direct board-level compatibility without design modification.

Supply Availability: The 5505204F is available in active inventory (1408 pcs), providing immediate procurement capability.

Frequently Asked Questions (FAQ)

Q: Can the 5505204F be used as a direct replacement for the 5505204 without circuit modification?

A: Yes. The 5505204F maintains identical electrical ratings (2.2V, 20mA), optical characteristics (green, 34mcd, 50° viewing angle), and through-hole mounting configuration. No circuit redesign is required.

Q: What is the difference between the lens size specifications "5.00mm Dia" and "5mm, T-1 3/4"?

A: Both designations refer to equivalent physical dimensions. The T-1 3/4 designation is an alternative industry standard notation for a 5mm diameter LED package. The mechanical compatibility is maintained.

Q: Why is the 5505204 classified as obsolete?

A: The 5505204 has been superseded by the 5505204F in Dialight's active product line. The 5505204F provides the same functional performance with enhanced compliance certifications and active manufacturing support.

Q: Are there any wavelength differences between the two parts?

A: The peak wavelengths differ slightly (565nm vs 563nm). This 2nm variance is within normal manufacturing tolerance for green LEDs and does not affect visual appearance or functional performance in circuit board indicator applications.

Q: What packaging options are available?

A: The 5505204 was supplied in standard packaging (not specified). The 5505204F is available in bulk packaging, suitable for production assembly operations.

Q: Are both parts RoHS compliant?

A: The 5505204F is certified ROHS3 compliant. The RoHS status of the 5505204 is not specified in the available documentation. The 5505204F provides confirmed environmental compliance for new designs and procurement.

Q: What is the moisture sensitivity level for these components?

A: Both parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
