LN05202P LED Circuit Board Indicator - 5 Segment Red Vertical

Part Overview

The LN05202P is a 5-segment red LED circuit board indicator manufactured by Panasonic Electronic Components. This component is configured as a bar-type SIP (Single In-line Package) indicator with five red LEDs arranged vertically. The part is currently classified as obsolete, making identification of suitable substitute components necessary for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LN05202P is determined by the following critical parameters that must align across components:

Physical Compatibility:

• Configuration: Bar - 5 Wide, SIP
• Lens Size: 5.30mm x 1.80mm
• Lens Style: Rectangle with Flat Top
• Mounting Type: Through Hole

Electrical Compatibility:

• Color: Red (x 5)
• Wavelength range: 660nm to 700nm (red spectrum)
• Voltage Rating: 1.7V to 2.2V
• Current Rating: 15mA to 30mA
• Millicandela Rating: 0.6mcd minimum

The SSA-LXB525SRD from Lumex Opto/Components Inc. meets all physical compatibility requirements and operates within acceptable electrical parameters for direct substitution in through-hole applications requiring a 5-segment red LED indicator bar.

Engineering Selection Recommendations

The SSA-LXB525SRD is a direct functional substitute for the LN05202P. Key selection factors:

Product Status: The LN05202P is obsolete, while the SSA-LXB525SRD is active and in production, ensuring long-term availability and supply chain continuity.

Compliance: The SSA-LXB525SRD is ROHS3 compliant, whereas the LN05202P is RoHS non-compliant. For applications subject to RoHS regulations, the Lumex component is the appropriate choice.

Electrical Performance: The SSA-LXB525SRD operates at a lower voltage (1.7V vs. 2.2V) and higher current (30mA vs. 15mA) with significantly higher brightness (40mcd vs. 0.6mcd). Circuit designs must accommodate these electrical differences through appropriate current-limiting resistor adjustments.

Physical Compatibility: Both components share identical physical dimensions, lens geometry, and through-hole mounting configuration, ensuring PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can the SSA-LXB525SRD replace the LN05202P without PCB modifications?

A: The SSA-LXB525SRD is physically compatible and requires no PCB layout changes. However, circuit design modifications are necessary to accommodate the different voltage and current ratings. Current-limiting resistors must be recalculated based on the 1.7V forward voltage and 30mA maximum current of the substitute component.

Q: What is the wavelength difference between these components?

A: The LN05202P operates at 700nm (deep red), while the SSA-LXB525SRD operates at 660nm (standard red). Both are within the red spectrum and visually appear red; however, the Lumex component produces a slightly brighter, more saturated red appearance due to its higher millicandela rating.

Q: Are there any compliance considerations for this substitution?

A: Yes. The LN05202P is RoHS non-compliant, while the SSA-LXB525SRD is ROHS3 compliant. For new designs or applications subject to RoHS directives, the Lumex component is the required choice.

Q: How does the brightness difference affect circuit design?

A: The SSA-LXB525SRD produces 40mcd compared to 0.6mcd for the LN05202P. This 66-fold increase in brightness may require adjustment of current-limiting resistor values to prevent over-driving the LEDs and to maintain consistent visual indication levels in the application.

Q: Are both components rated for unlimited moisture sensitivity?

A: Yes. Both the LN05202P and SSA-LXB525SRD carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
