Dialight 5505507 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5505507 is a single red LED circuit board indicator designed for through-hole, right-angle mounting applications. This component features a 5mm T-1 3/4 form factor with a clear, domed lens and operates at 2.2V with a 20mA current rating. The part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing production support and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Dialight 5505507 are classified into two categories based on electrical and mechanical compatibility:

Direct Substitutes (Dialight Series 550):

• 5505507F and 5505505F are direct equivalents manufactured by Dialight within the same 550 series
• These parts maintain identical electrical specifications: 20mA current, 2.2V voltage rating, 125mcd brightness, 635nm peak wavelength, and 24° viewing angle
• Mechanical compatibility is preserved: 5mm T-1 3/4 form factor, through-hole right-angle mounting, clear domed lens
• The primary distinction is packaging format (bulk versus original packaging) and product status (active versus obsolete)
• Both direct substitutes carry ROHS3 compliance certification

Similar Substitute (Broadcom HLMP-3750 Series):

• HLMP-3750-L00B2 is a functionally equivalent alternative from Broadcom Limited
• Electrical parameters align: 20mA current, 125mcd brightness, 635nm peak wavelength, 24° viewing angle, and through-hole right-angle mounting
• Critical difference: voltage rating is 1.9V versus 2.2V for the original part
• This voltage differential must be evaluated within the context of circuit design and power supply specifications
• Mechanical form factor and lens specifications differ in documentation notation but maintain functional equivalence for circuit board indicator applications

Engineering Selection Recommendations

For Direct Replacement (Preferred): Select either 5505507F or 5505505F when component availability and supply chain continuity are priorities. Both parts are active products from Dialight with ROHS3 compliance certification. The 5505507F maintains the exact base product number alignment with the original part, while 5505505F offers an alternative within the same series. Both preserve all electrical and mechanical specifications of the obsolete 5505507.

For Cross-Manufacturer Substitution: The Broadcom HLMP-3750-L00B2 is suitable when Dialight parts are unavailable. This part maintains electrical performance in brightness (125mcd), current (20mA), wavelength (635nm), and viewing angle (24°). The voltage rating difference (1.9V versus 2.2V) requires circuit-level evaluation to confirm compatibility with existing power supply and current-limiting resistor designs. ROHS3 compliance and REACH unaffected status align with regulatory requirements.

Compliance Considerations: All substitute parts carry ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the original component. Moisture sensitivity level remains constant at MSL 1 (unlimited) across all options, eliminating handling and storage requirement changes.

Frequently Asked Questions (FAQ)

Q: Can 5505507F and 5505505F be used interchangeably with the original 5505507? A: Yes. Both parts are direct Dialight equivalents with identical electrical specifications (2.2V, 20mA, 125mcd, 635nm, 24° viewing angle) and mechanical form factors (5mm T-1 3/4, through-hole right-angle mounting, clear domed lens). The primary difference is product status (active versus obsolete) and packaging format.

Q: What is the key difference between the Dialight and Broadcom substitutes? A: The Broadcom HLMP-3750-L00B2 operates at 1.9V compared to the 2.2V rating of Dialight parts. All other electrical parameters (current, brightness, wavelength, viewing angle) and mechanical specifications (mounting type, form factor) are equivalent. Circuit design compatibility must be confirmed before selection.

Q: Are there packaging differences between the substitute parts? A: The original 5505507 is specified with standard packaging. The direct substitutes 5505507F and 5505505F are supplied in bulk packaging. This distinction affects procurement and handling but does not impact component performance or compatibility.

Q: Do all substitute parts meet the same regulatory requirements? A: Yes. All substitute parts carry ROHS3 compliance, REACH unaffected status, EAR99 ECCN classification, and the same HTSUS code (8541.41.0000). Moisture sensitivity level remains MSL 1 (unlimited) across all options.

Q: Which substitute should be selected for new production designs? A: For new designs, select from the active Dialight parts (5505507F or 5505505F) or the Broadcom HLMP-3750-L00B2. All three are active products with current manufacturing support. Dialight parts provide direct series continuity, while the Broadcom option offers cross-manufacturer availability. Voltage rating compatibility with circuit design is the determining factor for the Broadcom selection.
