LDS-C412RI Equivalent & Substitute Parts

Part Overview

The LDS-C412RI is a single-character 7-segment LED display module manufactured by Lumex Opto/Components Inc. This green display operates as a common cathode configuration and is designed for numeric and alphanumeric applications requiring a 0.43-inch character size. The component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and package specifications align with the original component, enabling direct replacement in circuit designs without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LDS-C412RI is determined by strict alignment of the following critical parameters:

Display Configuration: Both the main part and substitute must be single-character 7-segment displays with common cathode configuration and green color output.

Package Compatibility: The 14-DIP (0.300", 7.62mm) package with 11 leads is mandatory for direct board-level replacement without layout modification.

Electrical Performance: Forward voltage, test current, power dissipation, and wavelength specifications must fall within acceptable operating ranges for the application circuit. Millicandela rating indicates brightness output and must be compatible with system visibility requirements.

Regulatory Compliance: RoHS3 compliance and MSL 1 rating ensure environmental and manufacturing process compatibility.

The HDSP-4603 manufactured by Broadcom Limited meets all substitution criteria for the LDS-C412RI based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: The LDS-C412RI remains the specified component when original manufacturer continuity and exact electrical parameters are required.

Substitute Selection: The HDSP-4603 is a qualified substitute when:

• Component availability for LDS-C412RI is limited or discontinued
• Forward voltage tolerance of 2.1V (versus 2.2V) is acceptable within circuit design margins
• Increased brightness output (4mcd versus 3.5mcd) does not create optical or power management conflicts
• Both components maintain identical RoHS3 compliance and MSL 1 ratings
• Both components are Active product status with ongoing manufacturer support

Compliance Verification: Both parts satisfy ROHS3 compliance, REACH unaffected status, and EAR99 export classification, ensuring regulatory alignment for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the HDSP-4603 be used as a direct replacement for the LDS-C412RI without PCB modification?

A: Yes. Both components use identical 14-DIP (0.300", 7.62mm) packaging with 11 leads, enabling direct pin-for-pin substitution without circuit board layout changes.

Q: What is the significance of the 0.1V forward voltage difference between these parts?

A: The LDS-C412RI operates at 2.2V typical forward voltage while the HDSP-4603 operates at 2.1V. This 0.1V difference is within normal component tolerance ranges and does not affect circuit functionality when proper current-limiting resistors are used in the design.

Q: Does the higher millicandela rating of the HDSP-4603 (4mcd versus 3.5mcd) create compatibility issues?

A: No. The increased brightness output of the HDSP-4603 is compatible with applications designed for the LDS-C412RI. The higher luminous intensity does not degrade performance and may improve visibility in high-ambient-light environments.

Q: Are there wavelength differences that affect color perception?

A: The wavelength difference is minimal (565nm for LDS-C412RI versus 566nm for HDSP-4603). Both emit green light within the same perceptual range and are visually indistinguishable in typical applications.

Q: What packaging format is used for the HDSP-4603?

A: The HDSP-4603 is supplied in Tube packaging, while the LDS-C412RI packaging format is not specified in the provided data. Verify packaging requirements for your procurement and assembly processes.

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

A: Yes. Both the LDS-C412RI and HDSP-4603 are ROHS3 compliant, REACH unaffected, classified as EAR99, and carry MSL 1 (unlimited moisture sensitivity) ratings, ensuring equivalent environmental and regulatory compliance.

Q: What is the basis for substitution eligibility between these two parts?

A: Substitution is based on matching display type (7-segment), character configuration (single character, common cathode), color (green), package format (14-DIP), electrical parameters (forward voltage, current, power dissipation), and regulatory compliance status.
