Dialight 5502504 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5502504 is a 5mm through-hole LED circuit board indicator featuring a single orange diffused lens with domed top. This component operates at 1.9V with 10mA current consumption and delivers 7 millicandela brightness at 600nm peak wavelength. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain identical electrical and mechanical specifications for direct board-level substitution.

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5502504 is determined by strict equivalence across all critical electrical and mechanical parameters. The following criteria establish direct substitutability:

Mandatory Matching Parameters:

• Color: Orange
• Wavelength - Peak: 600nm
• Configuration: Single
• Current Rating: 10mA
• Millicandela Rating: 7mcd
• Viewing Angle: 60°
• Lens Type: Diffused
• Lens Style: Round with Domed Top
• Lens Size: 5mm, T-1 3/4
• Voltage Rating: 1.9V
• Mounting Type: Through Hole
• Moisture Sensitivity Level: 1 (Unlimited)

All five identified substitute parts (5502504F, 5610901060F, 5610901070F, 5610901080F, 5610901100F) meet these requirements without exception. The primary distinction between the obsolete 5502504 and its substitutes is product status and packaging configuration. The 5502504F represents the direct line continuation within the 550 series, while the 561 series variants (5610901060F through 5610901100F) provide functionally equivalent alternatives from the successor product line.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Dialight 5502504F

The 5502504F is the direct active equivalent of the obsolete 5502504. Both components belong to the 550 series and maintain identical electrical and mechanical specifications. The 5502504F carries ROHS3 compliance certification and is currently in active production status with 928 units in stock. This part represents the preferred substitution path for direct replacement applications.

Secondary Substitutes: Dialight 561 Series (5610901060F, 5610901070F, 5610901080F, 5610901090F, 5610901100F)

The five variants from the 561 series provide functionally equivalent alternatives when 5502504F availability is constrained. All five parts maintain complete electrical and mechanical parity with the original 5502504 specification. Each 561 series variant carries ROHS3 compliance and active product status. Inventory levels range from 661 to 1157 units across the five part numbers, providing multiple sourcing options. Selection among these five variants may be determined by procurement lead time, inventory availability, or supplier preference, as all deliver identical performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 5610901 series parts directly replace the obsolete 5502504?

A: Yes. The 5610901060F, 5610901070F, 5610901080F, 5610901090F, and 5610901100F are direct functional equivalents. All electrical parameters (voltage, current, brightness, wavelength) and mechanical specifications (lens type, size, mounting) are identical to the 5502504. These parts are suitable for board-level substitution without circuit modification.

Q: What is the difference between 5502504F and the 5610901 series variants?

A: The 5502504F belongs to the 550 series product line and represents the direct continuation of the 5502504. The 5610901 series represents the successor product line (561 series). From an engineering perspective, both groups are electrically and mechanically equivalent. Selection may depend on supplier availability or procurement preference.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All five substitute parts (5502504F, 5610901060F, 5610901070F, 5610901080F, 5610901090F, 5610901100F) carry ROHS3 compliance certification. The original 5502504 does not specify RoHS status.

Q: Do the substitute parts have the same through-hole footprint as the 5502504?

A: Yes. All substitute parts maintain the identical 5mm T-1 3/4 through-hole package configuration. No PCB layout modifications are required for substitution.

Q: What is the inventory status of substitute parts?

A: All substitute parts are in active production with current stock: 5502504F (928 units), 5610901060F (661 units), 5610901070F (1031 units), 5610901080F (688 units), 5610901090F (1157 units), 5610901100F (684 units).

Q: Can I mix substitute parts from different series on the same board?

A: Yes. All substitute parts deliver identical optical and electrical performance. Mixed sourcing from 550 and 561 series variants presents no functional or compatibility issues.
