SM0805SRC LED Red Clear 0805 SMD - Equivalent & Substitute Parts

Part Overview

The SM0805SRC is a red LED indication component manufactured by Bivar Inc. in the 0805 (2012 Metric) surface mount package. This discrete LED operates at a forward voltage of 1.85V with a dominant wavelength of 640nm and peak wavelength of 660nm, delivering 28mcd at 20mA test current. The component features a rectangular flat-top lens with clear transparency and a 130° viewing angle.

The SM0805SRC is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications. Substitute parts must maintain compatibility across mechanical mounting, electrical performance parameters, and package specifications.

Engineering Selection Recommendations

SM0805RC as Substitute for SM0805SRC:

The SM0805RC is a direct mechanical and functional substitute for the SM0805SRC. Both components share identical package specifications, mounting characteristics, and physical dimensions, ensuring PCB compatibility without design modification.

Product Status Advantage: The SM0805RC carries Active product status, providing superior long-term availability and supply chain continuity compared to the obsolete SM0805SRC. This status supports ongoing production requirements and future component procurement.

Compliance and Certification: The SM0805RC is RoHS3 Compliant, meeting current environmental and regulatory standards for electronic component manufacturing and distribution.

Electrical Parameter Considerations: The SM0805RC operates at 2V forward voltage compared to the SM0805SRC at 1.85V. This 0.15V difference must be evaluated within the context of the specific circuit design. The SM0805RC wavelength specifications (645nm dominant, 700nm peak) remain within the red LED spectrum and maintain visual indication functionality.

Brightness Specification: The SM0805RC delivers 0.9mcd compared to the SM0805SRC at 28mcd. This represents a significant reduction in brightness output. Component selection must confirm that the lower brightness level satisfies the application's indication requirements.

Frequently Asked Questions (FAQ)

Q: Can SM0805RC be used as a direct replacement for SM0805SRC without PCB modification?

A: Yes. Both components share identical package specifications (0805 / 2012 Metric), physical dimensions (2.00mm L x 1.20mm W), and maximum height (1.10mm). No PCB layout changes are required for mechanical compatibility.

Q: What is the significance of the forward voltage difference between SM0805SRC (1.85V) and SM0805RC (2V)?

A: The 0.15V difference affects circuit design calculations for current-limiting resistor selection. Circuit designs must accommodate the SM0805RC's 2V forward voltage specification. Existing resistor values may require adjustment to maintain proper operating current at 20mA.

Q: Why does the SM0805RC have significantly lower brightness (0.9mcd vs. 28mcd)?

A: The millicandela rating difference reflects different LED die specifications within the same package. The SM0805RC is suitable for applications requiring lower brightness indication. Applications requiring 28mcd brightness output must confirm that 0.9mcd satisfies functional requirements before substitution.

Q: Are the wavelength specifications compatible between SM0805SRC and SM0805RC?

A: Both components produce red indication within the visible spectrum. The SM0805SRC dominant wavelength is 640nm (peak 660nm) while the SM0805RC is 645nm (peak 700nm). Both wavelengths fall within the red LED category and maintain visual indication consistency for standard red LED applications.

Q: What packaging format is available for SM0805RC?

A: The SM0805RC is supplied in Tape & Reel (TR) packaging format, suitable for automated assembly processes.

Q: Are moisture sensitivity requirements identical?

A: Yes. Both SM0805SRC and SM0805RC carry MSL 4 (72 Hours) rating, requiring identical storage and handling procedures to prevent moisture-related degradation.

Q: What is the inventory status for these components?

A: SM0805SRC has 933 Pcs in stock (obsolete status). SM0805RC has 1114 Pcs in stock (active status), providing greater availability for ongoing procurement needs.
