Display configuration: Single-character 7-segment red LED module with common anode architecture Physical compatibility: Identical external dimensions (0.750" H x 0.500" W x 0.250" D) Electrical characteristics: Forward voltage range 2V to 2.1V, test current 20mA Optical properties: Red wavelength (630nm to 635nm), brightness in the 0.84mcd to 1.12mcd range Environmental compliance: Moisture Sensitivity Level 1, REACH Unaffected status

The substitute part 5082-7650 from Broadcom Limited meets all substitution criteria while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The 5082-7650 from Broadcom Limited is the direct substitute for the obsolete 5082-7650_LBC. This part maintains identical physical dimensions, common anode configuration, and core electrical specifications (2.1V forward voltage, 20mA test current) required for drop-in replacement.

The Broadcom part offers active product status with current manufacturing support and improved inventory availability (2200 pcs in stock versus 879 pcs for the onsemi part). Both parts maintain REACH Unaffected compliance and Moisture Sensitivity Level 1 rating, ensuring equivalent environmental performance.

The Broadcom substitute exhibits a 0.1V increase in forward voltage (2.1V versus 2V) and a 33% increase in brightness (1.12mcd versus 0.84mcd), with a significant reduction in maximum power dissipation (105mW versus 840mW). These characteristics make the substitute suitable for applications requiring equal or greater display brightness with improved power efficiency.

Frequently Asked Questions (FAQ)

Q: Can the 5082-7650 from Broadcom Limited directly replace the 5082-7650_LBC in existing designs?

A: Yes. Both parts share identical physical dimensions, common anode configuration, and compatible electrical specifications. The 0.1V forward voltage difference (2.1V versus 2V) falls within typical circuit design tolerances for LED display applications.

Q: What is the significance of the different power dissipation ratings?

A: The Broadcom part specifies 105mW maximum power dissipation compared to 840mW for the onsemi part. This difference reflects improved LED efficiency in the Broadcom design. Both parts operate at the same 20mA test current, so the actual operating power consumption in your circuit will be determined by your specific current-limiting resistor design.

Q: Are there packaging differences between these parts?

A: The onsemi part (5082-7650_LBC) does not specify a package designation. The Broadcom substitute (5082-7650) is packaged in 14-DIP (0.300", 7.62mm) with 11 leads. Verify your PCB footprint compatibility with the 14-DIP package before implementation.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both the 5082-7650_LBC and 5082-7650 maintain Moisture Sensitivity Level 1 (Unlimited) and REACH Unaffected status, ensuring equivalent environmental performance and regulatory compliance.

Q: Why is the wavelength different between the two parts?

A: The onsemi part specifies 630nm peak wavelength while the Broadcom part specifies 635nm. Both wavelengths fall within the standard red LED spectrum and are visually indistinguishable in typical display applications. The 5nm difference reflects manufacturing variations between suppliers.
