Key Parameters

Substitute Part Grouping Explanation

The BA56-12GWA manufactured by Kingbright qualifies as a functional equivalent based on the following critical parameters that determine substitution compatibility:

Matching Parameters:

• Number of Characters: 3
• Digit/Alpha Size: 0.56" (14.22mm)
• Display Type: 7-Segment
• Common Pin Configuration: Common Anode
• Color: Green
• Current - Test: 20mA
• Wavelength - Peak: 565nm
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Product Status: Active

Allowable Variations:

• Voltage - Forward (Vf): 2.1V (LTC-561G) vs. 2.2V (BA56-12GWA) — within acceptable tolerance for common anode green LED displays
• Millicandela Rating: 2.4mcd (LTC-561G) vs. 8.6mcd (BA56-12GWA) — higher brightness in substitute provides enhanced visibility
• Power Dissipation: 75mW (LTC-561G) vs. 62.5mW (BA56-12GWA) — lower dissipation in substitute
• Package Configuration: 12-DIP (LTC-561G) vs. 28-DIP Module with 12 Leads (BA56-12GWA) — both utilize 0.600" (15.24mm) pitch standard DIP footprint

Parameter Comparison

Engineering Selection Recommendations

Both the LTC-561G and BA56-12GWA maintain active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts should be based on the following engineering criteria:

LTC-561G Selection Criteria:

• Applications requiring exact forward voltage specification of 2.1V
• Designs with brightness requirements matching 2.4mcd specification
• Existing inventory or supply chain optimization with Lite-On Inc. components

BA56-12GWA Selection Criteria:

• Applications benefiting from higher brightness output (8.6mcd vs. 2.4mcd)
• Designs where lower power dissipation (62.5mW vs. 75mW) provides system-level advantages
• Supply chain diversification or availability requirements
• Forward voltage tolerance of 2.2V acceptable within circuit design parameters

Both parts satisfy identical functional requirements for 3-character, 0.56-inch, 7-segment green common anode display applications with 20mA test current and 565nm peak wavelength operation.

Frequently Asked Questions (FAQ)

Q: Can BA56-12GWA directly replace LTC-561G in existing designs?

A: Yes, provided the circuit design accommodates the 0.1V forward voltage difference (2.1V vs. 2.2V) and the higher brightness output (8.6mcd vs. 2.4mcd). Both parts share identical character count, segment type, common anode configuration, test current, and wavelength specifications. PCB footprint compatibility depends on specific layout; both utilize standard 0.600" (15.24mm) pitch DIP spacing.

Q: What are the physical dimension differences between these parts?

A: LTC-561G dimensions are 0.750" H x 1.484" W x 0.315" D (19.05mm x 37.70mm x 8.00mm). BA56-12GWA dimensions are 1.480" H x 0.748" W x 0.319" D (37.60mm x 19.00mm x 8.10mm). The substitute has reversed height and width orientation. Verify mechanical clearance in your application before substitution.

Q: Are there compliance or certification differences?

A: Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Both are actively manufactured. No compliance barriers exist for substitution from a regulatory standpoint.

Q: How does the brightness difference affect circuit design?

A: The BA56-12GWA provides 8.6mcd versus 2.4mcd for the LTC-561G. If your circuit includes current-limiting resistors or brightness control, the substitute may produce noticeably brighter output at identical drive current. Adjust resistor values if brightness matching is required.

Q: What packaging differences should I consider?

A: LTC-561G uses 12-DIP packaging; BA56-12GWA uses 28-DIP Module configuration with 12 active leads. Both maintain 0.600" (15.24mm) standard DIP pitch. Verify that your PCB footprint accommodates the different pin count and physical layout before substitution.
