Dialight 5595201809F LED Panel Indicator Green Diffused

Part Overview

The Dialight 5595201809F is an LED panel indicator featuring a green diffused lens with a 50° viewing angle. This component is designed for snap-in panel mounting applications requiring a 0.25" (6.35mm) round cutout. The part operates at 2.2V forward voltage with a maximum current rating of 25mA and delivers 34mcd luminous intensity at a peak wavelength of 563nm. This Active product is ROHS3 compliant and REACH unaffected, making it suitable for modern electronic equipment design. Alternative models may be required when specific termination styles or inventory availability differ from application requirements.

Key Parameters

Substitute Part Grouping Explanation

The Dialight 5595201809F has one identified substitute within the 559 series: the 5595201001F. Both parts share identical electrical and optical specifications, including forward voltage (2.2V), maximum current (25mA), luminous intensity (34mcd), peak wavelength (563nm), and viewing angle (50°). Both feature the same mechanical interface: round panel cutout (0.25" / 6.35mm), 5mm T-1 3/4 lens size, and round domed top lens style.

The key differentiating parameter is termination style. The 5595201809F uses a standard termination, while the 5595201001F employs PC Pin termination. This distinction affects only the connection method to the circuit board and does not alter the optical or electrical performance characteristics. Both parts maintain identical compliance certifications (ROHS3 compliant, REACH unaffected) and moisture sensitivity ratings (MSL 1).

Substitution is valid when the circuit board design accommodates the specific termination style of the replacement part.

Parameter Comparison

Engineering Selection Recommendations

Both the 5595201809F and 5595201001F are Active products with current inventory availability. Selection between these parts depends solely on circuit board termination compatibility. The 5595201809F with standard termination is appropriate for designs using conventional through-hole or surface-mount pads. The 5595201001F with PC Pin termination is suitable for applications requiring direct pin insertion into PC-compatible sockets or connectors.

Both parts maintain identical ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across modern electronic equipment applications. The MSL 1 rating indicates unlimited shelf life under standard storage conditions, eliminating moisture-related handling constraints during assembly.

Frequently Asked Questions (FAQ)

Q: Can the 5595201001F replace the 5595201809F in an existing design?

A: Substitution is possible only if the circuit board design accommodates PC Pin termination. The electrical and optical specifications are identical, but the physical connection method differs. Board redesign or adapter solutions may be required.

Q: Are the optical characteristics identical between these parts?

A: Yes. Both parts deliver 34mcd luminous intensity at 563nm peak wavelength with a 50° viewing angle. The green diffused lens provides identical light distribution and color characteristics.

Q: What is the significance of the termination style difference?

A: Termination style determines how the LED connects to the circuit board. Standard termination uses conventional leads or pads, while PC Pin termination uses direct pin insertion. This affects only the assembly method and board layout, not electrical or optical performance.

Q: Are both parts suitable for new designs?

A: Yes. Both parts are Active products with current manufacturing status and adequate inventory. Selection should be based on circuit board termination requirements and design specifications.

Q: Do these parts have different compliance certifications?

A: No. Both parts are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements for modern electronic equipment.
