LTC-5337P 7-Segment LED Display - Equivalent & Substitute Parts

Part Overview

The LTC-5337P is a quad red 7-segment LED display module manufactured by Lite-On Inc., featuring a 0.52" character size in a 40-DIP package configuration. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and new design implementations. The display operates at 2.1V forward voltage with 20mA test current and is designed for common cathode applications requiring numeric or alphanumeric output.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LTC-5337P is determined by strict alignment of the following critical parameters:

• Display Configuration: 4-character, 7-segment, common cathode topology
• Physical Form Factor: 0.52" character size with 40-DIP package footprint
• Electrical Specifications: 2.1V forward voltage and 20mA test current rating
• Mechanical Compatibility: Identical external dimensions (0.689" H x 1.990" W x 0.276" D)
• Packaging Standard: 40-DIP (0.600", 15.24mm) pin spacing

The LTC-5337JD meets all mandatory substitution criteria. While secondary parameters such as millicandela rating, wavelength peak, and power dissipation differ, these variations remain within acceptable operational tolerances for common cathode 7-segment display applications and do not compromise functional compatibility or PCB integration.

Engineering Selection Recommendations

The LTC-5337JD is the primary substitute for the obsolete LTC-5337P. Selection is justified on the following engineering grounds:

Product Status: The LTC-5337JD maintains active production status with current inventory availability (945 Pcs), whereas the LTC-5337P is obsolete. This ensures long-term supply chain continuity and component availability for production and field replacement scenarios.

Compliance and Certification: The LTC-5337JD carries RoHS3 compliance certification, meeting modern regulatory requirements for electronic component manufacturing and environmental standards. Both parts maintain identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited), ensuring equivalent handling and storage requirements.

Functional Compatibility: Identical electrical parameters (2.1V forward voltage, 20mA test current) and mechanical form factor (40-DIP package, 0.52" character size, matching external dimensions) ensure direct PCB integration without circuit redesign or layout modification.

Secondary Parameter Variations: The LTC-5337JD exhibits a 0.1mcd reduction in millicandela rating (0.7mcd vs. 0.8mcd) and a 47nm shift in wavelength peak (650nm vs. 697nm), representing a shift toward standard red wavelength. Maximum power dissipation increases from 40mW to 70mW. These variations are characteristic of component evolution within the same product family and do not compromise display functionality in standard numeric or alphanumeric applications.

Frequently Asked Questions (FAQ)

Q: Can the LTC-5337JD be used as a direct replacement for the LTC-5337P without circuit modification?

A: Yes. Both parts share identical electrical specifications (2.1V forward voltage, 20mA test current), common cathode configuration, and 40-DIP package footprint with matching external dimensions. No circuit redesign is required for substitution.

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

A: The LTC-5337JD operates at 650nm, which is the standard red wavelength for LED displays. The LTC-5337P operates at 697nm, representing a deeper red spectrum. Both are red-colored displays suitable for numeric applications. Visual appearance may differ slightly under identical lighting conditions, but functional compatibility remains unchanged.

Q: Why does the LTC-5337JD have higher maximum power dissipation (70mW vs. 40mW)?

A: Power dissipation specifications reflect component design and manufacturing variations within the same product family. The increased rating does not indicate higher operating current or voltage requirements. Test current remains 20mA at 2.1V for both parts. The higher dissipation rating provides additional thermal margin and does not affect circuit operation.

Q: Is the LTC-5337JD RoHS compliant?

A: Yes. The LTC-5337JD carries RoHS3 compliance certification. The LTC-5337P does not specify RoHS status in the provided data. If RoHS compliance is a design requirement, the LTC-5337JD is the appropriate selection.

Q: Are there any inventory or lead time considerations?

A: The LTC-5337P is obsolete with limited remaining stock (1004 Pcs). The LTC-5337JD is in active production with current inventory of 945 Pcs. For new designs or long-term production, the LTC-5337JD is the recommended selection to ensure supply chain continuity.

Q: Do both parts require identical PCB footprints?

A: Yes. Both the LTC-5337P and LTC-5337JD use the 40-DIP (0.600", 15.24mm) package with identical pin spacing and external dimensions. Existing PCB layouts require no modification for substitution.
