LTC-5336P 7-Segment LED Display - Equivalent & Substitute Parts

Part Overview

The LTC-5336P is a 3-character red 7-segment LED display module manufactured by Lite-On Inc., designed for numeric and alphanumeric display applications. This component features a common cathode configuration with a 0.52-inch character height and 30-DIP packaging. The LTC-5336P is currently classified as obsolete, making identification of suitable substitute components essential for ongoing production support, maintenance, and new design implementations where this display type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LTC-5336P is determined by strict alignment of the following critical parameters:

• Display Configuration: 3-character, 7-segment, common cathode architecture
• Physical Compatibility: 0.52-inch character height, 30-DIP package footprint, matching overall dimensions (0.689" H x 1.490" W x 0.276" D)
• Electrical Specifications: Forward voltage of 2.1V typical, red color emission
• Mechanical Interface: 30-DIP (0.600", 15.24mm) pin spacing and package form factor

The LTC-5336JD qualifies as a manufacturer-recommended substitute based on identical display configuration, character count, common cathode topology, character height, physical dimensions, package type, and forward voltage specification. Variations in test current, luminous intensity, wavelength, and power dissipation do not preclude substitution when the primary functional and mechanical parameters align.

Engineering Selection Recommendations

The LTC-5336JD is the manufacturer-recommended substitute for the obsolete LTC-5336P. Selection of the LTC-5336JD is supported by the following factors:

• Product Status: The LTC-5336JD maintains active product status, ensuring continued availability and manufacturing support, whereas the LTC-5336P is obsolete.
• Compliance: The LTC-5336JD is RoHS3 compliant, meeting current regulatory requirements for electronic components in restricted substance directives.
• Functional Equivalence: Both components share identical display architecture, character configuration, common cathode topology, character height, package footprint, and forward voltage specification.
• Mechanical Compatibility: The 30-DIP package and physical dimensions are identical, ensuring direct PCB footprint compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the LTC-5336JD be used as a direct replacement for the LTC-5336P in existing designs?

A: Yes. The LTC-5336JD is mechanically and electrically compatible with the LTC-5336P. Both components use the 30-DIP package with identical physical dimensions and pin spacing. The common cathode configuration, character height, and forward voltage are identical, enabling direct substitution without PCB redesign.

Q: What are the differences between the LTC-5336P and LTC-5336JD?

A: The primary differences are test current (20mA vs. 1mA), millicandela rating (0.8mcd vs. 0.7mcd), wavelength peak (697nm vs. 650nm), and product status (obsolete vs. active). The LTC-5336JD also carries RoHS3 compliance certification. These variations do not affect mechanical compatibility or basic functional operation.

Q: Why is the LTC-5336P classified as obsolete?

A: The LTC-5336P has reached end-of-life status in the manufacturer's product portfolio. The LTC-5336JD represents the active equivalent within the same product family, offering continued manufacturing support and regulatory compliance.

Q: Are there any package or pinout differences between these components?

A: No. Both the LTC-5336P and LTC-5336JD use the 30-DIP (0.600", 15.24mm) package with identical physical dimensions of 0.689" H x 1.490" W x 0.276" D. Pin configuration and spacing are identical, ensuring direct PCB compatibility.

Q: What is the significance of the wavelength difference (697nm vs. 650nm)?

A: Both wavelengths fall within the red spectrum range. The 697nm wavelength of the LTC-5336P produces a deeper red appearance, while the 650nm wavelength of the LTC-5336JD produces a brighter red appearance. Selection depends on visual requirements and application-specific color preferences.
