LDS-A512RI Equivalent & Substitute Parts

Part Overview

The LDS-A512RI is a 7-segment LED display module manufactured by Lumex Opto/Components Inc. This single-character green display operates as a common anode configuration and is housed in a 10-DIP package. The device is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent display modules share the same physical package, electrical interface topology, and core functional characteristics. Alternative sources become necessary due to inventory availability, supply chain considerations, or specific application requirements within the allowable parameter ranges.

All substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) classification. Substitutes are limited to active production status devices.

Parameter Comparison

Engineering Selection Recommendations

LDS-A512RI (Primary Part): The LDS-A512RI operates at 2.2V forward voltage with 10mA test current and 3.9mcd brightness. This part maintains REACH Unaffected status and is available in bulk packaging. The device is suitable for applications requiring lower current draw and standard brightness levels.

LTS-6460G (Lite-On Substitute): The LTS-6460G operates at 2.1V forward voltage with 20mA test current and 2.4mcd brightness. This substitute exhibits lower power dissipation (75mW) compared to the primary part. The LTS-6460G carries REACH Affected designation. Physical dimensions show minimal variance (0.750" height versus 0.748"). This part is available in tube packaging.

SA56-21GWA (Kingbright Substitute): The SA56-21GWA operates at 2.2V forward voltage with 20mA test current and 11mcd brightness. This substitute provides the highest brightness rating among the three options and the lowest power dissipation (62.5mW). The SA56-21GWA maintains REACH Unaffected status. Physical dimensions show minimal variance (0.750" height, 0.500" width versus 0.748" height, 0.496" width). This part is available in tube packaging.

All three parts maintain active production status, ROHS3 compliance, and Moisture Sensitivity Level 1 (Unlimited) classification. Selection between substitutes depends on specific application requirements for brightness, current consumption, and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the LTS-6460G replace the LDS-A512RI in all applications?

A: The LTS-6460G shares the same 10-DIP package, common anode configuration, and 0.56" digit size. The forward voltage differs by 0.1V (2.1V versus 2.2V), and test current is doubled (20mA versus 10mA). Physical height is 0.002" greater (0.750" versus 0.748"). These parameters fall within allowable substitution ranges. However, the LTS-6460G carries REACH Affected status, whereas the LDS-A512RI is REACH Unaffected. Applications subject to REACH compliance requirements must account for this designation.

Q: What is the brightness difference between these parts?

A: The LDS-A512RI provides 3.9mcd brightness. The LTS-6460G provides 2.4mcd brightness (38% lower). The SA56-21GWA provides 11mcd brightness (182% higher). All three parts emit at the same 565nm wavelength (green). Selection depends on application visibility requirements.

Q: Are there physical fit concerns when substituting these parts?

A: All three parts use the 10-DIP (0.600", 15.24mm) package. Physical height variance is 0.002" (0.748" to 0.750"), and width variance is 0.004" (0.496" to 0.500"). These tolerances are within standard PCB footprint design margins. Depth is consistent at 0.315" across all parts. No physical fit issues are expected in standard DIP socket applications.

Q: Which substitute offers the lowest power consumption?

A: The SA56-21GWA provides the lowest maximum power dissipation at 62.5mW, compared to 75mW for the LTS-6460G and 105mW for the LDS-A512RI. However, the SA56-21GWA requires 20mA test current, whereas the LDS-A512RI requires only 10mA. Power consumption depends on actual operating current in the application circuit.

Q: What is the difference between REACH Affected and REACH Unaffected status?

A: REACH Unaffected parts (LDS-A512RI and SA56-21GWA) are not subject to REACH regulatory restrictions. REACH Affected parts (LTS-6460G) are subject to REACH compliance requirements. Applications operating in European Union markets or subject to REACH compliance must select parts with REACH Unaffected status or verify compliance documentation for REACH Affected parts.

Q: Can these parts be used interchangeably in existing designs?

A: Electrical interchangeability is confirmed for common anode 7-segment display applications. All parts operate within the 2.1V to 2.2V forward voltage range and accept 10mA to 20mA test current. PCB footprints designed for 10-DIP packages accommodate all three parts. However, circuit designs must account for brightness differences (2.4mcd to 11mcd range) and current requirements (10mA to 20mA range). Regulatory compliance status (REACH) must be verified for the intended application market.
