5082-7653_LBC Red 7-Segment LED Display Equivalent & Substitute Parts

Part Overview

The 5082-7653_LBC is a single-character red 7-segment LED display module manufactured by onsemi. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The display operates at 2V forward voltage with a 20mA test current and features a 0.43-inch digit height in a common cathode configuration. Identifying compatible alternatives ensures design flexibility and supply chain resilience for applications requiring this display category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5082-7653_LBC is determined by the following critical parameters:

• Display Type & Configuration: Must be 7-segment, single character, common cathode
• Physical Dimensions: Must match 0.750" H x 0.500" W x 0.250" D (19.05mm x 12.70mm x 6.35mm)
• Digit Height: Must be 0.43" (10.92mm ±0.08mm tolerance range)
• Color & Wavelength: Red spectrum (630nm–635nm acceptable range)
• Electrical Ratings: Forward voltage 2V–2.1V, test current 20mA
• Common Pin Type: Common cathode only

The substitute parts 5082-7653 and 5082-7653-DE000 (both Broadcom Limited) meet these criteria. Both maintain identical display type, character count, physical envelope, digit size, color specification, and electrical operating parameters within acceptable engineering tolerances. Packaging and lead count variations do not affect functional substitution in applications where the display module itself is the critical component.

Engineering Selection Recommendations

Primary Substitute: 5082-7653 (Broadcom Limited)

The 5082-7653 is the preferred substitute for the obsolete 5082-7653_LBC. This part maintains active product status, ensuring long-term availability and supply chain stability. It is RoHS3 compliant, providing regulatory advantage over the original onsemi part. The forward voltage increase from 2V to 2.1V is within standard LED operating tolerance and does not require circuit redesign. The improved millicandela rating (1.12mcd vs. 0.84mcd) and reduced power dissipation (105mW vs. 840mW) represent performance enhancements. Packaging is specified as 14-DIP with 11 leads.

Secondary Substitute: 5082-7653-DE000 (Broadcom Limited)

The 5082-7653-DE000 is functionally equivalent to the primary substitute but is classified as obsolete. This part is electrically and mechanically identical to 5082-7653, with the exception of lead count (10 leads vs. 11 leads in the primary substitute). Selection of this part should be limited to applications where existing inventory is available or where the specific 10-lead configuration is required. RoHS3 compliance is maintained.

Both Broadcom substitutes are suitable for direct replacement in applications where the 5082-7653_LBC was originally specified, provided that the PCB footprint and lead configuration are compatible with the selected substitute variant.

Frequently Asked Questions (FAQ)

Q: Can the 5082-7653 directly replace the 5082-7653_LBC without circuit modification?

A: Yes. The forward voltage difference (2.1V vs. 2V) is within standard LED operating tolerance and does not require circuit redesign. The common cathode configuration, digit size, and electrical test current are identical. PCB footprint compatibility must be verified based on the specific packaging variant selected.

Q: What is the difference between 5082-7653 and 5082-7653-DE000?

A: Both parts are electrically and mechanically equivalent. The primary difference is lead count: 5082-7653 has 11 leads in a 14-DIP package, while 5082-7653-DE000 has 10 leads in a 14-DIP package. Selection depends on PCB footprint requirements and available inventory.

Q: Why is the power dissipation specification significantly lower in the Broadcom substitutes?

A: The power dissipation values (105mW vs. 840mW) reflect different measurement methodologies or operating conditions specified by each manufacturer. Both parts operate at the same 20mA test current and are suitable for the same applications. Consult the detailed datasheet for specific operating condition definitions.

Q: Are the Broadcom substitutes RoHS compliant?

A: Yes. Both 5082-7653 and 5082-7653-DE000 are RoHS3 compliant, providing regulatory advantage over the original onsemi part, which does not specify RoHS status.

Q: What is the wavelength difference between 630nm and 635nm?

A: The 5nm difference falls within the red LED spectrum and is not visually distinguishable in typical applications. Both wavelengths are classified as red and are suitable for direct substitution.

Q: Is the 5082-7653_LBC still available for purchase?

A: The 5082-7653_LBC is classified as obsolete. The Broadcom 5082-7653 (active status) is the recommended alternative for new designs and ongoing production requirements.
