HDSP-K213 Equivalent & Substitute Parts

Part Overview

The HDSP-K213 is a dual-character red 7-segment LED display module manufactured by Broadcom Limited. This component is classified as an active product and is designed for numeric and alphanumeric display applications requiring common cathode configuration. The HDSP-K213 operates at 2V forward voltage with a 20mA test current and delivers 2.8mcd brightness at a peak wavelength of 635nm. Finding equivalent substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and accommodate varying inventory availability across manufacturing partners.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HDSP-K213 is determined by strict alignment of the following critical parameters:

• Display Configuration: 2-character, 7-segment, common cathode architecture
• Electrical Specifications: 2V forward voltage and 20mA test current
• Optical Properties: Red color at 635nm peak wavelength
• Package Type: 18-DIP (0.600", 15.24mm) form factor
• Regulatory Compliance: ROHS3 compliance and MSL rating

The LTD-6940HR from Lite-On Inc. meets all mandatory substitution criteria. Both parts share identical display type, common cathode configuration, electrical operating parameters, wavelength specification, and package footprint. Dimensional variations in overall height (0.670" vs 0.750") and width (0.990" vs 0.984") remain within acceptable mechanical tolerances for standard PCB mounting applications. Both components maintain ROHS3 compliance and unlimited moisture sensitivity ratings.

Parameter Comparison

Engineering Selection Recommendations

Both the HDSP-K213 and LTD-6940HR are active products with full ROHS3 compliance and unlimited moisture sensitivity ratings, making either component suitable for production applications. The HDSP-K213 offers higher brightness output at 2.8mcd compared to the LTD-6940HR at 2.4mcd, and exhibits higher maximum power dissipation at 105mW versus 75mW. The LTD-6940HR provides lower power consumption characteristics while maintaining identical electrical and optical operating parameters. Selection between these parts should be based on specific brightness requirements and thermal design constraints of the application. Both components are packaged in standard 18-DIP form factor with compatible pinout and mounting footprint.

Frequently Asked Questions (FAQ)

Q: Can the LTD-6940HR directly replace the HDSP-K213 in existing designs?

A: Yes. Both parts share identical 18-DIP package pinout, common cathode configuration, 2V forward voltage, 20mA test current, and 635nm red wavelength specification. Dimensional differences in height and width are minor and do not affect standard PCB mounting compatibility.

Q: What are the key differences between these two parts?

A: The primary differences are brightness output (HDSP-K213: 2.8mcd vs LTD-6940HR: 2.4mcd) and maximum power dissipation (HDSP-K213: 105mW vs LTD-6940HR: 75mW). Overall dimensions vary slightly, with the LTD-6940HR being taller by 0.080" and slightly narrower by 0.006".

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the HDSP-K213 and LTD-6940HR are ROHS3 compliant with unlimited moisture sensitivity ratings (MSL 1), suitable for standard manufacturing and storage conditions.

Q: Which part should be selected for brightness-critical applications?

A: The HDSP-K213 delivers higher luminous intensity at 2.8mcd, making it the appropriate choice for applications requiring maximum brightness output.

Q: Are there any package or pinout differences that affect circuit board layout?

A: Both parts use the standard 18-DIP (0.600", 15.24mm) package with identical pinout. Minor dimensional variations do not impact PCB footprint design or component placement.
