Dialight 5500304 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5500304 is a 5mm through-hole LED circuit board indicator featuring a single yellow diffused lens with domed top. This component delivers 12.3 millicandela at 20mA forward current with a 2.1V forward voltage rating and 60° viewing angle. The part is classified as obsolete, making identification of active equivalent substitutes essential for ongoing production and maintenance applications requiring this specific LED indicator type.

Key Parameters

Substitute Part Grouping Explanation

The Dialight 5500304F qualifies as a direct substitute based on the following critical electrical and mechanical parameters:

Matching Parameters:

• Color: Yellow (585nm peak wavelength)
• Configuration: Single LED
• Forward Current: 20mA
• Millicandela Rating: 12.3mcd
• Viewing Angle: 60°
• Lens Type: Diffused
• Forward Voltage: 2.1V
• Mounting Type: Through Hole
• Series: 550
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected
• ECCN: EAR99
• HTSUS Code: 8541.41.0000

The 5500304F maintains identical electrical performance and optical characteristics while transitioning from obsolete to active product status. The primary distinction is packaging format (bulk versus standard packaging) and the absence of specified lens style and size descriptors in the substitute part documentation, though the 5mm through-hole form factor remains consistent.

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5500304F is the appropriate substitute for the obsolete 5500304. Both parts maintain identical electrical specifications (20mA forward current, 2.1V forward voltage, 12.3mcd brightness) and optical characteristics (yellow 585nm wavelength, 60° viewing angle, diffused lens). The substitute part carries active product status with ROHS3 compliance certification, providing supply chain continuity and regulatory alignment for new designs and production restocking.

Selection of the 5500304F eliminates obsolescence risk while preserving circuit compatibility and performance requirements for through-hole LED indicator applications.

Frequently Asked Questions (FAQ)

Q: Can the 5500304F directly replace the 5500304 in existing circuit designs?

A: Yes. Both parts share identical electrical ratings (20mA, 2.1V), optical output (12.3mcd at 585nm), and through-hole mounting configuration. No circuit modifications are required.

Q: What is the primary reason for substitution?

A: The 5500304 is classified as obsolete. The 5500304F is the active equivalent from the same manufacturer and series, ensuring continued availability and supply chain reliability.

Q: Are there compliance differences between the two parts?

A: The 5500304F carries ROHS3 compliance certification. Both parts maintain REACH Unaffected status and identical ECCN/HTSUS classifications.

Q: Does packaging format affect electrical or mechanical compatibility?

A: No. The packaging difference (bulk versus standard) does not impact electrical performance, optical characteristics, or through-hole mounting compatibility. Component selection depends on procurement quantity requirements.

Q: Are the lens specifications identical?

A: Both parts feature diffused yellow lenses with 60° viewing angle and 5mm form factor. The 5500304 specifies "round with domed top" lens style; the 5500304F documentation does not include this descriptor, though the physical form factor remains consistent with the 5mm through-hole standard.
