Dialight 5505607 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5505607 is a 5mm green LED circuit board indicator designed for through-hole, right-angle mounting applications. This component features a clear, domed lens with a peak wavelength of 565nm and operates at 2.3V with a 20mA current rating, delivering 120mcd brightness at a 24° viewing angle. The part is classified as obsolete, making identification of active equivalent and substitute components essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5505607 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Color: Green (565nm peak wavelength)
• Configuration: Single LED
• Current Rating: 20mA
• Mounting Type: Through Hole, Right Angle
• Lens Type: Clear
• Viewing Angle: 24°

Allowable Variation Ranges:

• Voltage Rating: ±0.1V tolerance (2.2V to 2.4V acceptable)
• Millicandela Rating: Equal or greater brightness acceptable
• Lens Size: 5.00mm diameter standard

Two substitute parts meet these criteria:

Direct Substitute (Dialight 5505607F): Active product from the same manufacturer and series, maintaining identical electrical and mechanical specifications with bulk packaging.

Similar Substitute (Broadcom HLMP-3950-K00B2): Active product from alternative manufacturer with matching core parameters. Voltage rating of 2.2V falls within acceptable tolerance. Millicandela rating of 265mcd exceeds the original specification, providing enhanced brightness capability.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: The Dialight 5505607F is the primary substitute. As an active product from the original manufacturer within the same 550 series, it maintains identical electrical and mechanical specifications. ROHS3 compliance and active product status provide supply chain continuity and regulatory alignment for new designs and production runs.

For Alternative Sourcing: The Broadcom HLMP-3950-K00B2 serves as a secondary substitute when Dialight 5505607F availability is constrained. The 0.1V voltage differential (2.2V vs. 2.3V) remains within standard operating tolerances for LED circuit board indicator applications. The increased millicandela rating (265mcd vs. 120mcd) provides enhanced brightness, which is acceptable for applications where the original brightness specification represents a minimum requirement rather than a maximum constraint. ROHS3 compliance and active product status support regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the Dialight 5505607F directly replace the obsolete 5505607 without circuit modification?

A: Yes. The 5505607F maintains identical voltage rating (2.3V), current rating (20mA), wavelength (565nm), viewing angle (24°), and mounting configuration (through hole, right angle). No circuit modifications are required.

Q: Is the Broadcom HLMP-3950-K00B2 compatible with the original 5505607 design?

A: The HLMP-3950-K00B2 is compatible with the original design specifications. The voltage rating of 2.2V is within acceptable tolerance for LED indicator applications. The increased brightness (265mcd vs. 120mcd) does not create incompatibility; however, circuit designers should confirm that the higher brightness does not create visual or functional issues in the target application.

Q: What is the significance of the voltage difference between 5505607 (2.3V) and HLMP-3950-K00B2 (2.2V)?

A: The 0.1V difference represents a 4.3% variance and falls within standard operating tolerances for LED indicators. Both parts operate within the same forward voltage range for green LEDs and are suitable for identical circuit designs without modification.

Q: Are there packaging differences between the main part and substitutes?

A: The original 5505607 is specified with "-" packaging notation. The 5505607F is supplied in bulk packaging. The HLMP-3950-K00B2 is also supplied in bulk packaging. Procurement teams should confirm packaging requirements for their specific application and supply chain processes.

Q: Do all three parts meet current regulatory compliance standards?

A: The 5505607F and HLMP-3950-K00B2 are both ROHS3 compliant and REACH unaffected. The original 5505607 does not specify RoHS status. For new designs and regulated applications, the active substitutes (5505607F or HLMP-3950-K00B2) are recommended to ensure compliance documentation.

Q: What is the primary reason to select one substitute over the other?

A: Select the Dialight 5505607F for direct manufacturer continuity and identical specifications. Select the Broadcom HLMP-3950-K00B2 when Dialight availability is limited and the enhanced brightness capability (265mcd) is acceptable for the application. Both parts meet the core electrical and mechanical requirements of the obsolete 5505607.
