Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELF-511UBWA/C470 is determined by the following critical parameters:

Mechanical Compatibility:

• 4-character configuration
• 0.56" character size
• 12-DIP package footprint (0.600", 15.24mm)
• Physical dimensions: 0.748" H × 1.984" W × 0.315" D

Electrical Compatibility:

• 7-segment display type
• Common cathode pin configuration
• Blue color emission
• 20mA test current rating
• Forward voltage within acceptable operating range

Environmental & Compliance:

• MSL rating of 1 or equivalent
• ECCN and HTSUS classifications

The LTC-5753B-01 from Lite-On Inc. meets all mechanical and electrical compatibility criteria. While forward voltage differs (3.8V vs. 3.5V), both operate within standard LED display operating parameters and share identical package, character count, display type, and common cathode configuration.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The ELF-511UBWA/C470 is classified as obsolete. The LTC-5753B-01 is an active product from Lite-On Inc., ensuring ongoing availability and supply chain continuity.

Compliance & Certifications: Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. The LTC-5753B-01 carries RoHS3 compliance certification, providing additional environmental regulatory alignment for new designs or production runs.

Electrical Parameter Differences: The LTC-5753B-01 operates at 3.8V forward voltage compared to the 3.5V of the ELF-511UBWA/C470. This 0.3V difference is within standard LED display operating tolerances. The substitute part exhibits lower power dissipation (65mW vs. 130mW) and reduced millicandela rating (4.3mcd vs. 6.4mcd), with a peak wavelength shift from 468nm to 428nm. These differences reflect manufacturing variations between suppliers but do not affect functional compatibility in standard 7-segment display applications.

Package & Mechanical Compatibility: Both parts are identical in physical dimensions, character count, package type (12-DIP), and mechanical footprint, ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the LTC-5753B-01 be used as a direct replacement for the ELF-511UBWA/C470?

A: Yes. Both parts share identical mechanical footprints, 12-DIP package specifications, 4-character configuration, 0.56" character size, common cathode pin configuration, and 20mA test current rating. The forward voltage difference (3.8V vs. 3.5V) and wavelength shift (428nm vs. 468nm) are within acceptable operating parameters for 7-segment display applications.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Manufacturer—Everlight Electronics vs. Lite-On Inc.; (2) Forward voltage—3.5V vs. 3.8V; (3) Millicandela rating—6.4mcd vs. 4.3mcd; (4) Peak wavelength—468nm vs. 428nm; (5) Power dissipation—130mW vs. 65mW; (6) Product status—Obsolete vs. Active; (7) Compliance—No RoHS certification vs. RoHS3 compliant.

Q: Will the brightness difference affect my application?

A: The ELF-511UBWA/C470 has a higher millicandela rating (6.4mcd) than the LTC-5753B-01 (4.3mcd). Brightness perception depends on viewing distance, ambient lighting, and application requirements. The wavelength difference (468nm vs. 428nm) represents a shift within the blue spectrum range.

Q: Are there any PCB layout changes required?

A: No. Both parts have identical physical dimensions (0.748" H × 1.984" W × 0.315" D), 12-DIP package footprint (0.600", 15.24mm), and pin configuration. Direct PCB substitution is possible without layout modifications.

Q: What is the MSL rating for both parts?

A: Both the ELF-511UBWA/C470 and LTC-5753B-01 have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Is the LTC-5753B-01 RoHS compliant?

A: Yes. The LTC-5753B-01 is RoHS3 compliant. The ELF-511UBWA/C470 does not list RoHS certification status in the provided specifications.

Q: What is the operating current for both displays?

A: Both parts have a test current rating of 20mA, ensuring compatible drive circuit requirements.
