HDSP-5703-FG000 Equivalent & Substitute Parts

Part Overview

The HDSP-5703-FG000 is a 7-segment LED display module manufactured by Broadcom Limited, featuring a single yellow character with 0.56" digit height in a 10-DIP package configuration. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and production continuity. The display operates at 2.1V forward voltage with 20mA test current and delivers 1.8mcd brightness output at a peak wavelength of 583nm.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HDSP-5703-FG000 is determined by strict equivalence across the following critical parameters:

• Display Type: 7-Segment configuration
• Number of Characters: Single character only
• Digit/Alpha Size: 0.56" (14.22mm) nominal dimension
• Color: Yellow LED emission
• Common Pin Configuration: Common Cathode topology
• Voltage - Forward (Vf) (Typ): 2.1V operation
• Current - Test: 20mA specification
• Package / Case: 10-DIP (0.600", 15.24mm) footprint
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The SC56-11YWA from Kingbright meets all mandatory substitution criteria. Physical dimension variations in overall height and width (0.750" H x 0.500" W versus 0.670" H x 0.495" W) remain within acceptable mechanical tolerance ranges for standard PCB mounting applications. Electrical parameters including forward voltage, test current, and package footprint are identical.

Parameter Comparison

Engineering Selection Recommendations

The SC56-11YWA qualifies as a direct functional substitute for the HDSP-5703-FG000 based on electrical and mechanical parameter equivalence. The Kingbright component is currently in active production status, ensuring supply chain availability and long-term sourcing stability compared to the obsolete Broadcom part.

Both components carry identical REACH and ECCN classifications (REACH Unaffected, EAR99), confirming regulatory compliance parity. The SC56-11YWA holds RoHS3 compliance certification, supporting environmental and regulatory requirements for modern manufacturing.

Physical dimension differences are minor and do not impact standard 10-DIP socket compatibility or PCB layout considerations. The increased brightness output (6.5mcd versus 1.8mcd) and slightly extended wavelength (590nm versus 583nm) represent performance enhancements rather than incompatibilities, with both values remaining within the yellow LED spectrum range.

Frequently Asked Questions (FAQ)

Q: Can the SC56-11YWA replace the HDSP-5703-FG000 in existing designs?

A: Yes. Both components share identical electrical specifications (2.1V forward voltage, 20mA test current), common cathode configuration, and 10-DIP package footprint. The physical dimension variance is minor and does not affect standard mounting or circuit operation.

Q: What are the key differences between these parts?

A: The SC56-11YWA offers higher brightness (6.5mcd versus 1.8mcd), operates at a slightly longer wavelength (590nm versus 583nm), and consumes marginally less power (75mW versus 80mW). The Kingbright part is in active production, whereas the Broadcom component is obsolete.

Q: Are there any compliance or regulatory differences?

A: Both components carry identical REACH and ECCN classifications. The SC56-11YWA includes RoHS3 compliance certification, providing additional environmental compliance assurance.

Q: Will the increased brightness of the SC56-11YWA affect circuit design?

A: No. Both components operate at identical voltage and current specifications. The brightness increase results from improved LED efficiency and does not require circuit modifications.

Q: Are there any package or pinout differences?

A: No. Both components use the 10-DIP (0.600", 15.24mm) package with identical pinout configuration. Direct socket substitution is supported.
