LSHD-F101 Equivalent & Substitute Parts

Part Overview

The LSHD-F101 is a red 7-segment LED display module manufactured by Lite-On Inc., designed for single-character numeric and alphanumeric display applications. This common anode configuration operates at 2.1V forward voltage with a 20mA test current, housed in a standard 10-DIP package. The component is currently active in production and ROHS3 compliant, making it suitable for modern electronic applications requiring compact display solutions.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the same package type and functional category, ensuring direct replacement capability in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LSHD-F101 is determined by the following critical parameters:

• Display Type & Configuration: Must be 7-segment LED, single character, common anode
• Package Type: Must be 10-DIP (0.300", 7.62mm) for direct PCB compatibility
• Digit Size: Must be 0.39" (10.00mm) for visual consistency
• Color: Must be red wavelength (630-660nm range)
• Electrical Compatibility: Forward voltage and test current must support operation within standard LED driver circuit parameters
• Compliance: Must maintain ROHS3 compliance for regulatory equivalence

The LDS-A3914RI from Lumex Opto/Components Inc. meets these substitution criteria, sharing identical package geometry, display configuration, and compliance status while operating within compatible electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the LSHD-F101 and LDS-A3914RI are active production components with ROHS3 compliance and MSL Level 1 rating, confirming regulatory equivalence for modern applications. The primary selection criterion is electrical performance alignment with circuit design specifications.

The LSHD-F101 operates at 2.1V with 20mA test current and delivers 9.75mcd brightness. The LDS-A3914RI operates at 2.0V with 10mA test current and delivers 5.6mcd brightness. Both components share identical package geometry and common anode configuration, enabling direct pinout compatibility.

Selection between these parts depends on circuit current budget and brightness requirements. The lower current consumption of the LDS-A3914RI may be advantageous in power-constrained applications, while the higher brightness of the LSHD-F101 suits visibility-critical designs. Both wavelengths (650nm vs 635nm) fall within standard red LED specifications and are visually indistinguishable in typical applications.

Frequently Asked Questions (FAQ)

Q: Can the LDS-A3914RI directly replace the LSHD-F101 on existing PCBs?

A: Yes. Both components use identical 10-DIP (0.300", 7.62mm) package geometry with common anode pin configuration. No PCB modifications are required for physical or electrical substitution.

Q: What are the differences in electrical operation between these parts?

A: The LSHD-F101 operates at 2.1V with 20mA test current, while the LDS-A3914RI operates at 2.0V with 10mA test current. The 0.1V difference is within typical LED driver tolerance. The current difference reflects different brightness levels (9.75mcd vs 5.6mcd). Circuit design must accommodate these specifications.

Q: Are there compliance or regulatory differences?

A: No. Both components are ROHS3 compliant with MSL Level 1 rating and identical ECCN/HTSUS classifications, confirming regulatory equivalence.

Q: How do the brightness levels compare?

A: The LSHD-F101 provides 9.75mcd at 20mA, while the LDS-A3914RI provides 5.6mcd at 10mA. The LSHD-F101 delivers approximately 74% higher brightness. Application visibility requirements determine which brightness level is appropriate.

Q: Are the physical dimensions identical?

A: Dimensions are similar but not identical. LSHD-F101: 12.90mm x 9.70mm x 6.10mm. LDS-A3914RI: 13.00mm x 10.00mm x 7.00mm. Differences are within typical component tolerance and do not affect standard PCB mounting or clearance considerations.

Q: What wavelength differences exist?

A: LSHD-F101 peak wavelength is 650nm; LDS-A3914RI is 635nm. Both fall within standard red LED specifications and produce visually equivalent red color in typical applications.
