Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LTC-571G is determined by the following critical parameters:

• Display Configuration: 3-character, 7-segment, common cathode architecture
• Digit Size: 0.56" (14.22mm) character height
• Color and Wavelength: Green at 565nm peak wavelength
• Electrical Specifications: Forward voltage (Vf) within acceptable operating range, test current of 20mA
• Package Type: 12-DIP (0.600", 15.24mm) pin spacing
• Compliance: ROHS3 compliance and MSL rating of 1

The BC56-12GWA manufactured by Kingbright meets all substitution criteria. Both parts share identical display type, character count, common cathode configuration, digit size, color, wavelength, test current, package type, and compliance certifications. Minor variations in forward voltage (2.1V vs. 2.2V) and power dissipation remain within acceptable engineering tolerances for this component category.

Parameter Comparison

Engineering Selection Recommendations

Both the LTC-571G and BC56-12GWA are active production components with ROHS3 compliance and MSL rating of 1. Selection between these parts should be based on:

LTC-571G (Lite-On Inc.): Primary choice when original manufacturer specification is required or when lower forward voltage (2.1V) is preferred for power budget optimization.

BC56-12GWA (Kingbright): Suitable alternative offering higher brightness (8.6mcd vs. 2.4mcd) and lower maximum power dissipation (62.5mW vs. 75mW). Forward voltage of 2.2V remains within standard operating parameters for common cathode 7-segment display applications.

Both parts maintain identical package footprint, pin configuration, and electrical interface requirements, enabling direct PCB-level substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can BC56-12GWA replace LTC-571G in existing designs? A: Yes. Both parts share identical 12-DIP package footprint, pin spacing (0.600", 15.24mm), common cathode configuration, and electrical interface. Direct substitution is supported without PCB modification.

Q: What is the difference in brightness between these parts? A: BC56-12GWA provides 8.6mcd brightness compared to LTC-571G at 2.4mcd. This higher brightness may require circuit current limiting adjustment depending on application requirements.

Q: Are there voltage compatibility concerns? A: Forward voltage differs by 0.1V (2.1V vs. 2.2V). This variation is within normal operating tolerance for 7-segment display applications and does not require circuit redesign.

Q: Do both parts meet the same compliance standards? A: Yes. Both LTC-571G and BC56-12GWA are ROHS3 compliant with MSL rating of 1 (Unlimited moisture sensitivity level).

Q: What is the wavelength specification for both parts? A: Both parts operate at 565nm peak wavelength, ensuring identical green color appearance in display applications.

Q: Are there packaging differences? A: LTC-571G is supplied in standard packaging, while BC56-12GWA is supplied in tube packaging. Both maintain identical component dimensions and 12-DIP configuration.
