Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HDSP-H403 is determined by strict equivalence across the following critical parameters:

Display Configuration: Single character, 7-segment architecture with 0.56" digit height and orange color emission Electrical Interface: Common cathode configuration with 10-DIP package pinout Optical Characteristics: 600nm peak wavelength and 2.37mcd luminous intensity Electrical Performance: 20mA test current and maximum 105mW power dissipation Physical Form Factor: 10-DIP (0.600", 15.24mm) package with identical external dimensions

The HDSP-H413 meets all substitution criteria through identical mechanical packaging, pinout compatibility, display type, character configuration, color, and optical wavelength. Forward voltage tolerance (2.0V vs. 2.1V) remains within acceptable operating margins for common cathode 7-segment LED display applications.

Parameter Comparison

Engineering Selection Recommendations

The HDSP-H413 is the direct equivalent for HDSP-H403 applications. The substitute part maintains active product status with Broadcom Limited, ensuring continued availability and manufacturing support. Both components carry identical REACH Unaffected and ECCN EAR99 classifications, confirming regulatory equivalence.

The 0.1V forward voltage differential (2.0V vs. 2.1V) is within standard operating tolerances for common cathode 7-segment LED display circuits and does not require circuit redesign. Current limiting resistor values may require minor adjustment based on specific application voltage supply and brightness requirements, but pinout and functional compatibility remain unchanged.

The HDSP-H413 is packaged in Bulk format with significantly higher inventory availability (7780 pcs vs. 937 pcs), supporting production continuity for new designs and legacy system maintenance.

Frequently Asked Questions (FAQ)

Q: Can HDSP-H413 directly replace HDSP-H403 without PCB modifications?

A: Yes. Both parts share identical 10-DIP pinout, physical dimensions, and common cathode configuration. No PCB layout changes are required for direct substitution.

Q: What is the significance of the 0.1V forward voltage difference?

A: The forward voltage variance (2.0V vs. 2.1V) is within standard LED display operating margins. Circuit current limiting resistors may require recalculation for optimal brightness, but functional compatibility is maintained across standard 5V and 3.3V supply designs.

Q: Are there any compliance or certification differences between these parts?

A: No. Both HDSP-H403 and HDSP-H413 carry identical REACH Unaffected and ECCN EAR99 classifications. Moisture Sensitivity Level (MSL) is identical at Level 1 (Unlimited).

Q: Why is HDSP-H403 classified as obsolete?

A: Broadcom Limited has transitioned the HDSP-H403 to obsolete status. The HDSP-H413 represents the active equivalent for ongoing production and design applications.

Q: Are optical characteristics identical between these displays?

A: Yes. Both parts deliver 2.37mcd luminous intensity at 600nm peak wavelength with identical 20mA test current specifications.

Q: What packaging formats are available for each part?

A: HDSP-H403 is available in standard packaging format. HDSP-H413 is supplied in Bulk packaging with higher inventory levels, supporting volume production requirements.
