LDS-A5202RI Equivalent & Substitute Parts

Part Overview

The LDS-A5202RI is a single-character 7-segment LED display module manufactured by Lumex Opto/Components Inc. This green display operates with common anode configuration and is housed in a 10-DIP package. The component is classified as Active product status with full RoHS3 compliance and REACH unaffected designation.

Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameter ranges for 7-segment display modules. The primary substitute maintains identical physical dimensions, display type, color, and common pin configuration while operating within compatible voltage and current specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LDS-A5202RI is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Display Type: 7-Segment configuration
• Number of Characters: Single character (1)
• Digit/Alpha Size: 0.52" (13.21mm)
• Color: Green
• Common Pin Configuration: Common Anode
• Voltage - Forward (Vf): 2.2V nominal
• Physical Dimensions: 0.689" H x 0.488" W x 0.276" D (17.50mm x 12.40mm x 7.00mm)
• Package Category: 10-DIP

Allowable Variation Parameters:

• Current - Test: May vary within circuit design limits
• Millicandela Rating: May vary based on application brightness requirements
• Power Dissipation: Varies with current specification
• Package Pitch: Minor tolerance within DIP standard (0.585" to 0.600")

The substitute part SA52-11GWA meets all critical matching parameters and maintains functional equivalence within the allowed electrical parameter ranges.

Parameter Comparison

Engineering Selection Recommendations

LDS-A5202RI Selection Criteria:

• Primary choice when circuit design specifies 10mA test current
• Suitable for applications requiring lower power dissipation (112mW maximum)
• Appropriate for designs with lower brightness requirements (3mcd)
• Maintains Active product status with full RoHS3 compliance

SA52-11GWA Selection Criteria:

• Suitable for applications requiring higher brightness output (10.5mcd)
• Appropriate when circuit design accommodates 20mA test current
• Lower maximum power dissipation (62.5mW) may benefit thermal management in certain applications
• Maintains Active product status with full RoHS3 compliance
• Package pitch tolerance (0.600" vs 0.585") remains within 10-DIP standard specifications

Both parts maintain identical compliance certifications (RoHS3 Compliant, REACH Unaffected, MSL 1) and are classified as Active products. Selection between these parts depends on circuit current requirements and brightness specifications rather than regulatory or availability factors.

Frequently Asked Questions (FAQ)

Q: Can SA52-11GWA directly replace LDS-A5202RI in existing circuit designs?

A: Direct replacement is possible when the circuit design accommodates the higher test current specification (20mA vs 10mA). The identical forward voltage (2.2V), common anode configuration, and physical dimensions ensure mechanical and electrical compatibility. Circuit current-limiting resistor values may require adjustment based on the application's brightness requirements.

Q: What is the significance of the different millicandela ratings (3mcd vs 10.5mcd)?

A: Millicandela rating indicates luminous intensity. The SA52-11GWA provides approximately 3.5 times higher brightness output than the LDS-A5202RI. Selection depends on application visibility requirements and ambient lighting conditions. Higher brightness may increase power consumption and heat generation in the circuit.

Q: Are the package pitch differences (0.585" vs 0.600") a concern for PCB compatibility?

A: Both parts use 10-DIP package classification with pitch differences within standard DIP tolerance ranges. PCB footprints designed for standard 10-DIP spacing accommodate both variants. Verify specific PCB design specifications if tight mechanical tolerances are required.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both LDS-A5202RI and SA52-11GWA are RoHS3 Compliant, REACH Unaffected, and classified as Moisture Sensitivity Level 1 (Unlimited). Both maintain Active product status, ensuring continued availability and support.

Q: What factors should determine which part to select?

A: Selection is based on three primary factors: (1) circuit current specification (10mA vs 20mA), (2) required brightness level (3mcd vs 10.5mcd), and (3) power dissipation constraints. Both parts are functionally equivalent within their respective electrical parameter ranges and maintain identical compliance certifications.
