Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LDS-AD12RI is determined by the following criteria:

Mechanical Compatibility Requirements:

• Identical display type (7-Segment)
• Single character configuration
• Common anode pin arrangement
• Green color emission
• Matching digit/alpha size of 2.24" (56.90mm)
• 10-DIP package format with compatible pin spacing

Electrical Operating Parameters:

• Forward voltage (Vf) within acceptable circuit design range
• Peak wavelength at 565nm (green spectrum)
• Current and power dissipation ratings suitable for driver circuit implementation

Compliance & Status:

• Active product status
• RoHS3 compliance maintained
• REACH unaffected classification

The SA23-11GWA from Kingbright satisfies all mechanical compatibility requirements and maintains equivalent compliance certifications. Electrical parameter variations exist and must be evaluated against specific circuit design constraints.

Parameter Comparison

Engineering Selection Recommendations

LDS-AD12RI Selection Criteria: The LDS-AD12RI is appropriate for applications requiring lower current consumption (10mA test current) and lower power dissipation (105mW maximum). This device is suitable for battery-powered or low-power circuit implementations where brightness requirements are moderate (6.3mcd).

SA23-11GWA Selection Criteria: The SA23-11GWA is appropriate for applications requiring higher brightness output (65mcd) and higher current capacity (20mA test current). This device accommodates higher power dissipation (250mW maximum) and is suitable for applications demanding increased luminous intensity or longer viewing distances.

Compliance Basis: Both devices maintain Active product status and ROHS3 compliance. Both devices are classified as REACH Unaffected and carry identical MSL ratings. Selection between these parts is based on electrical performance requirements rather than compliance or availability considerations.

Frequently Asked Questions (FAQ)

Q: Can SA23-11GWA replace LDS-AD12RI in existing circuit designs?

A: Mechanical and functional compatibility is confirmed. The SA23-11GWA operates at 8.8V forward voltage compared to 8.4V for the LDS-AD12RI. Circuit design must accommodate this 0.4V difference. The SA23-11GWA requires 20mA test current versus 10mA for the LDS-AD12RI, and dissipates up to 250mW versus 105mW. Driver circuits must be evaluated for current sourcing capability and thermal management.

Q: Are the 10-DIP packages mechanically interchangeable?

A: Both devices use 10-DIP package format with pin spacing of 60.10mm. The LDS-AD12RI package dimension is 2.367" (60.10mm) and the SA23-11GWA is 2.370" (60.10mm). These dimensions are functionally equivalent for PCB footprint and socket compatibility.

Q: What is the brightness difference between these displays?

A: The SA23-11GWA provides 65mcd brightness rating compared to 6.3mcd for the LDS-AD12RI. This represents approximately 10x higher luminous intensity. Application visibility requirements determine which brightness level is appropriate.

Q: Do both devices use the same pin configuration?

A: Both devices are common anode 7-segment displays in 10-DIP packages. Pin configuration and segment labeling are identical, confirming direct functional compatibility.

Q: What compliance certifications apply to both parts?

A: Both LDS-AD12RI and SA23-11GWA maintain ROHS3 compliance, REACH Unaffected status, and MSL Level 1 (Unlimited) moisture sensitivity rating. Both devices are classified as Active products.
