LA-301DL 7-Segment LED Display - Equivalent & Substitute Parts

Part Overview

The LA-301DL is a single-character 7-segment LED display module manufactured by Rohm Semiconductor. It features an orange light-emitting diode configuration with common cathode architecture, designed for numeric and alphanumeric display applications. The device operates at 2V forward voltage with a 15mA test current and produces 6.3 millicandela output at a 610nm peak wavelength.

The LA-301DL is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure component availability for production, and support long-term system maintenance where original inventory is depleted.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for 7-segment LED display modules is determined by the following critical parameters:

• Display type (7-segment architecture)
• Number of characters (single character)
• Digit/alpha size (0.31" / 8.00mm)
• Common pin configuration (common cathode)
• Color (orange)
• Forward voltage (2V nominal)
• Package type (10-DIP form factor)
• Compliance certifications (RoHS3, REACH)

The HDSP-U413 manufactured by Broadcom Limited meets all primary substitution criteria. While secondary parameters such as test current (20mA vs. 15mA), millicandela rating (5.39mcd vs. 6.3mcd), wavelength peak (600nm vs. 610nm), and power dissipation (105mW vs. 40mW) differ, these variations remain within acceptable tolerances for common cathode 7-segment display applications and do not prevent functional substitution.

Parameter Comparison

Engineering Selection Recommendations

The HDSP-U413 is a direct functional substitute for the LA-301DL. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

The HDSP-U413 carries active product status from Broadcom Limited, ensuring ongoing availability and supply chain continuity. The LA-301DL obsolete status makes the HDSP-U413 the appropriate selection for new designs, production restocking, and system maintenance requiring component replacement.

Both devices share identical package geometry (10-DIP), common cathode configuration, and nominal forward voltage (2V), enabling direct pin-compatible substitution in existing circuit designs without PCB modification.

Frequently Asked Questions (FAQ)

Q: Can the HDSP-U413 replace the LA-301DL in existing designs?

A: Yes. Both components are 10-DIP common cathode 7-segment displays with 0.31" digit size, 2V forward voltage, and identical package footprint. Direct substitution is possible without circuit redesign.

Q: What are the differences in electrical performance?

A: The HDSP-U413 operates at 20mA test current versus 15mA for the LA-301DL. Peak wavelength differs by 10nm (600nm vs. 610nm), and millicandela rating is 5.39mcd versus 6.3mcd. Maximum power dissipation is 105mW versus 40mW. These differences reflect manufacturing variations between manufacturers and do not prevent functional substitution in standard display applications.

Q: Are both components compliant with current regulations?

A: Yes. Both the LA-301DL and HDSP-U413 are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.

Q: What is the significance of the product status difference?

A: The LA-301DL is obsolete, indicating Rohm Semiconductor no longer manufactures or supports this component. The HDSP-U413 is active, meaning Broadcom Limited continues production and maintains supply availability. For new applications and long-term component sourcing, the active HDSP-U413 is the recommended selection.

Q: Are there any package or form factor considerations?

A: Both components use identical 10-DIP (0.209", 5.30mm) packaging. Physical dimensions differ slightly in height and width (LA-301DL: 0.275" H x 0.433" W; HDSP-U413: 0.433" H x 0.280" W), but both fit standard 10-pin DIP sockets and PCB layouts designed for this package type.
