Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5505604 is determined by strict equivalence across the following critical parameters:

• Color: Green (565nm peak wavelength)
• Voltage Rating: 2.3V
• Current: 20mA
• Millicandela Rating: 120mcd
• Viewing Angle: 24°
• Lens Type: Clear
• Lens Size: 5.00mm diameter
• Mounting Type: Through Hole
• Configuration: Single

The substitute part 5505604F maintains complete electrical and mechanical compatibility with the original 5505604, differing only in product status (active versus obsolete) and packaging designation (bulk). Both parts belong to the Dialight 550 series and share identical performance characteristics, making 5505604F a direct functional equivalent suitable for replacement in applications currently using 5505604.

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5505604F is the designated substitute for the obsolete 5505604. Selection of 5505604F is based on:

• Active product status ensuring ongoing availability and supply chain continuity
• Complete electrical parameter equivalence (2.3V, 20mA, 120mcd, 565nm)
• Identical mechanical specifications (5.00mm through-hole mounting, 24° viewing angle, clear domed lens)
• Equivalent regulatory compliance (REACH Unaffected, EAR99 classification)
• Identical moisture sensitivity rating (MSL 1)
• RoHS3 compliance certification on the substitute part

For applications currently using 5505604, direct substitution with 5505604F requires no circuit modifications or design changes. Both parts are functionally interchangeable within the specified electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can 5505604F be used as a direct replacement for 5505604?

A: Yes. The 5505604F is a direct functional equivalent. All critical electrical parameters (voltage, current, brightness, wavelength) and mechanical specifications (lens size, mounting type, viewing angle) are identical. The primary difference is product status: 5505604 is obsolete while 5505604F is active.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by matching: color (green), peak wavelength (565nm), voltage rating (2.3V), current (20mA), brightness (120mcd), viewing angle (24°), lens type and size (clear, 5.00mm diameter), and mounting method (through-hole). All these parameters are identical between 5505604 and 5505604F.

Q: Does packaging differ between these parts?

A: Yes. The 5505604 is listed with standard packaging, while 5505604F is supplied in bulk packaging. This is a logistical difference only and does not affect component performance or compatibility.

Q: Are there any compliance or regulatory differences?

A: No. Both parts share identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS code (8541.41.0000). The 5505604F carries RoHS3 compliance certification.

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

A: Both 5505604 and 5505604F have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
