HDSP-5621 Equivalent & Substitute Parts

Part Overview

The HDSP-5621 is a 2-character, 7-segment LED display module manufactured by Broadcom Limited. It features a 0.56" digit height with common anode configuration, green color output, and 18-DIP packaging. The device operates at 2.1V forward voltage with 10mA test current and delivers 2.5mcd brightness. This part is Active status and fully RoHS3 compliant. Substitute parts are necessary when the original HDSP-5621 is unavailable, when alternative brightness or current characteristics better suit application requirements, or when supply chain optimization is needed while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the HDSP-5621 is determined by the following mandatory parameters:

• Display Configuration: 2 characters, 7-segment, common anode
• Digit Height: 0.56" (14.22mm)
• Package Type: 18-DIP (0.600", 15.24mm)
• Color: Green
• Voltage Range: Forward voltage within acceptable operating tolerance
• Regulatory Compliance: RoHS3 compliance required

All three substitute parts—DA56-11CGKWA (Kingbright), LBP-602MA2 (Rohm Semiconductor), and LTD-6410G (Lite-On Inc.)—meet these core substitution criteria. Variations in test current (10mA vs. 20mA), brightness (2.5mcd to 100mcd), and wavelength (565nm to 574nm) represent performance differences that do not prevent functional substitution but may affect circuit design considerations such as current-limiting resistor values and visual brightness perception.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain Active product status and full RoHS3 compliance, ensuring long-term availability and regulatory alignment with the original HDSP-5621.

DA56-11CGKWA (Kingbright): Operates at identical 2.1V forward voltage with doubled test current (20mA) and significantly higher brightness (35mcd). Suitable for applications requiring enhanced visibility. Moisture Sensitivity Level 1 matches the original part.

LBP-602MA2 (Rohm Semiconductor): Operates at reduced forward voltage (1.9V) with matching 10mA test current and highest brightness rating (100mcd). Moisture Sensitivity Level 3 requires controlled storage conditions. Power dissipation specification (896mW) differs substantially from other parts and requires circuit verification.

LTD-6410G (Lite-On Inc.): Operates at identical 2.1V forward voltage with doubled test current (20mA) and brightness comparable to the original (2.4mcd). Moisture Sensitivity Level 1 matches the original part. REACH Status is Affected, requiring compliance verification for specific applications.

Frequently Asked Questions (FAQ)

Q: Can I directly replace HDSP-5621 with any of these substitute parts without circuit modification?

A: All three substitute parts share identical 18-DIP package configuration and common anode pinout, enabling direct physical replacement. However, differences in test current (10mA vs. 20mA) and forward voltage (1.9V to 2.1V) may require adjustment of current-limiting resistor values to maintain proper brightness and circuit performance.

Q: What is the primary difference between these substitute parts?

A: The main differences are brightness rating (2.4mcd to 100mcd), test current (10mA or 20mA), and forward voltage (1.9V or 2.1V). LBP-602MA2 offers the highest brightness but operates at lower voltage. DA56-11CGKWA and LTD-6410G operate at 2.1V matching the original but draw higher current.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all three substitute parts are RoHS3 compliant. However, LTD-6410G has REACH Status Affected, requiring compliance verification for specific end-use applications.

Q: What is the significance of Moisture Sensitivity Level differences?

A: HDSP-5621, DA56-11CGKWA, and LTD-6410G all have MSL 1 (Unlimited), requiring no special moisture control during storage and handling. LBP-602MA2 has MSL 3 (168 Hours), requiring controlled storage conditions and bake-out procedures before soldering if moisture exposure exceeds specified limits.

Q: Which substitute part most closely matches the original HDSP-5621 specifications?

A: LTD-6410G provides the closest electrical match with identical 2.1V forward voltage and comparable brightness (2.4mcd vs. 2.5mcd). DA56-11CGKWA also operates at 2.1V but with higher brightness and current draw. LBP-602MA2 differs with lower forward voltage (1.9V) and significantly higher brightness (100mcd).
