DA56-51EWA Equivalent & Substitute Parts

Part Overview

The DA56-51EWA is a 7-segment LED display module manufactured by Kingbright, featuring dual red character display in a 0.56-inch format with common anode configuration. This component is classified as an active product and is RoHS3 compliant. The display operates at 2V forward voltage with 20mA test current and is housed in an 18-DIP package measuring 0.600 inches (15.24mm) pitch.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across different manufacturers. Alternative models may be required due to inventory availability, packaging format preferences, or specific application performance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DA56-51EWA is determined by the following critical parameters:

Primary Compatibility Criteria:

• Number of Characters: 2
• Display Type: 7-Segment
• Digit/Alpha Size: 0.56 inches (14.22mm)
• Common Pin Configuration: Common Anode
• Color: Red
• Package Type: 18-DIP (0.600", 15.24mm pitch)

Secondary Electrical Parameters:

• Voltage - Forward (Vf) Typical: 2.0V (tolerance range acceptable)
• Current - Test: 20mA
• RoHS3 Compliance: Required
• Moisture Sensitivity Level: 1 (Unlimited)

The HDSP-521A and HDSP-K211 satisfy all primary compatibility criteria. Both are manufactured by Broadcom Limited and maintain the same mechanical footprint, character count, display format, and DIP package configuration. Electrical parameters remain within acceptable operating ranges for common anode 7-segment display applications.

Parameter Comparison

Engineering Selection Recommendations

HDSP-521A (Broadcom Limited)

The HDSP-521A is functionally equivalent to the DA56-51EWA for applications requiring common anode 7-segment red LED display modules. Both parts maintain identical mechanical compatibility and DIP package specifications. The HDSP-521A operates at 1.85V forward voltage compared to the DA56-51EWA's 2.0V, resulting in lower power dissipation (30mW versus 75mW). Brightness output is comparable at 6.5mcd versus 6.4mcd. Both parts are RoHS3 compliant with unlimited moisture sensitivity rating. The HDSP-521A is supplied in tube packaging, matching the DA56-51EWA format.

HDSP-K211 (Broadcom Limited)

The HDSP-K211 provides mechanical and electrical compatibility with identical 2.0V forward voltage and 20mA test current specifications. This part maintains the same 18-DIP package footprint and common anode configuration. The HDSP-K211 exhibits lower brightness output at 2.8mcd and higher maximum power dissipation at 105mW. This part is supplied in bulk packaging rather than tube format. RoHS3 compliance and unlimited moisture sensitivity rating are maintained.

Both substitute parts are active products with full regulatory compliance. Selection between alternatives depends on packaging requirements (tube versus bulk) and application-specific brightness and power dissipation constraints.

Frequently Asked Questions (FAQ)

Q: Can the HDSP-521A directly replace the DA56-51EWA in existing circuit designs?

A: Yes. Both parts share identical mechanical footprint (18-DIP, 0.600" pitch), common anode configuration, and 20mA test current. The HDSP-521A operates at 1.85V forward voltage versus the DA56-51EWA's 2.0V, which may require minor resistor value adjustments in current-limiting circuits but does not prevent direct substitution.

Q: What is the primary difference between HDSP-521A and HDSP-K211?

A: The HDSP-521A and HDSP-K211 differ in packaging format (tube versus bulk), brightness output (6.5mcd versus 2.8mcd), and maximum power dissipation (30mW versus 105mW). Both maintain identical mechanical compatibility and common anode 7-segment configuration.

Q: Are all three parts RoHS3 compliant?

A: Yes. The DA56-51EWA, HDSP-521A, and HDSP-K211 are all RoHS3 compliant with moisture sensitivity level 1 (unlimited).

Q: Does the wavelength difference between parts affect circuit operation?

A: Wavelength differences (627nm for DA56-51EWA, 660nm for HDSP-521A, 635nm for HDSP-K211) represent variations in red color perception but do not affect electrical circuit operation. Selection based on wavelength depends on visual appearance requirements in the end application.

Q: Which substitute part has lower power consumption?

A: The HDSP-521A has the lowest maximum power dissipation at 30mW, compared to 75mW for the DA56-51EWA and 105mW for the HDSP-K211.

Q: Can packaging format (tube versus bulk) affect circuit performance?

A: Packaging format does not affect electrical or mechanical circuit performance. Tube and bulk packaging are handling and storage formats only. Selection depends on inventory management and assembly process requirements.
