Broadcom 5082-7661 Yellow 7-Segment LED Display - Equivalent & Substitute Parts

Part Overview

The Broadcom 5082-7661 is a single-character yellow 7-segment LED display module in 14-DIP packaging. This part is classified as obsolete, making equivalent substitutes necessary for new designs and production continuity. The display operates at 2.2V forward voltage with 20mA test current and features common anode configuration suitable for standard microcontroller interfacing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Broadcom 5082-7661 is determined by the following critical parameters:

• Display type and character count (7-segment, single character)
• Digit/alpha size range (0.43" nominal)
• Common pin configuration (common anode)
• Color specification (yellow)
• Package type (14-DIP with 0.300" pitch)
• Electrical compatibility (forward voltage and current ratings within acceptable operating range)

The Kingbright SA43-11YWA qualifies as a direct substitute based on matching all primary functional and mechanical parameters. Minor variations in forward voltage (2.1V vs 2.2V), brightness rating (6.5mcd vs 0.84mcd), and wavelength (590nm vs 583nm) remain within acceptable tolerances for standard 7-segment display applications and do not preclude interchangeability in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

The Kingbright SA43-11YWA is the qualified substitute for the obsolete Broadcom 5082-7661. Selection is based on:

• Active product status ensuring long-term availability and supply chain continuity
• Identical package type (14-DIP) and pin pitch (0.300") enabling direct PCB compatibility
• Matching common anode configuration and 7-segment display architecture
• ROHS3 compliance and unlimited moisture sensitivity rating matching the original specification
• Forward voltage differential of 0.1V (2.1V vs 2.2V) within standard design margins for LED display circuits
• Higher brightness rating (6.5mcd vs 0.84mcd) providing improved visibility without requiring circuit modification

Frequently Asked Questions (FAQ)

Q: Can the Kingbright SA43-11YWA be used as a direct replacement without circuit modification?

A: Yes. The SA43-11YWA maintains identical package type, pin pitch, common anode configuration, and test current rating. The 0.1V forward voltage difference does not require circuit redesign for standard microcontroller-based display applications.

Q: What is the significance of the brightness difference between the two parts?

A: The Kingbright part has a higher millicandela rating (6.5mcd vs 0.84mcd). This represents improved luminous intensity and does not negatively impact compatibility. Existing circuit designs will function without modification, with the benefit of enhanced display visibility.

Q: Are the physical dimensions compatible for PCB mounting?

A: Yes. Both parts use 14-DIP (0.300", 7.62mm) package type with matching pin pitch. Dimensional variations (0.750" vs 0.748" height, 0.500" vs 0.496" width) are within standard manufacturing tolerances and do not affect PCB footprint compatibility.

Q: Does the wavelength difference affect color perception?

A: The wavelength difference (583nm vs 590nm) represents a minor shift within the yellow spectrum. Both parts are specified as yellow and will appear visually equivalent in standard applications.

Q: What compliance certifications apply to the substitute part?

A: The Kingbright SA43-11YWA carries ROHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) rating, matching the original part's regulatory profile.
