Key Parameters

Substitute Part Grouping Explanation

Substitution of the OVSASBLCR8 is determined by the following critical parameters:

• Color specification (Red)
• Forward voltage compatibility (2.5V nominal)
• Wavelength range (dominant wavelength 628nm)
• Millicandela output (2200mcd at 50mA test current)
• Viewing angle (60°)
• Lens configuration (Round with Domed Top, 2.60mm diameter)
• Surface mount capability with compatible package footprint
• Compliance certifications (ROHS3, REACH Unaffected)

The OVSA1SBLCR8 qualifies as a direct substitute based on matching these parameters within acceptable engineering tolerances for LED indication applications.

Parameter Comparison

Engineering Selection Recommendations

The OVSA1SBLCR8 is the manufacturer-recommended substitute for the obsolete OVSASBLCR8. Both components maintain identical forward voltage (2.5V) and test current (50mA) specifications, ensuring circuit compatibility without design modification. The substitute delivers marginally higher luminous intensity (2240mcd versus 2200mcd), which is within acceptable tolerance for indication applications.

Both parts carry ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements. The OVSA1SBLCR8 is currently in active production with established supply availability, whereas the OVSASBLCR8 is obsolete. The substitute's 4-SMD J-Lead package provides equivalent surface mount functionality with minor dimensional variations (width 2.70mm versus 2.80mm, height 4.65mm versus 3.45mm) that remain within standard PCB layout tolerances for LED indication circuits.

Frequently Asked Questions (FAQ)

Q: Can the OVSA1SBLCR8 be used as a direct replacement for OVSASBLCR8 without circuit modification?

A: Yes. Both components operate at identical forward voltage (2.5V) and test current (50mA). The substitute maintains the same color, viewing angle, and lens configuration. No circuit redesign is required.

Q: What is the wavelength difference between these parts?

A: The OVSASBLCR8 has a dominant wavelength of 628nm, while the OVSA1SBLCR8 is specified at 624nm. This 4nm difference falls within the red LED spectrum and is not visually distinguishable in indication applications.

Q: Are there package compatibility considerations?

A: The main part uses 4-PLCC packaging while the substitute uses 4-SMD J-Lead packaging. Both are surface mount configurations with compatible footprints for standard PCB assembly. Minor dimensional variations (width and height) are within typical PCB layout tolerances.

Q: Do both parts meet current compliance standards?

A: Yes. Both the OVSASBLCR8 and OVSA1SBLCR8 are ROHS3 compliant and REACH Unaffected, meeting current regulatory requirements for electronic components.

Q: Why is the OVSASBLCR8 obsolete?

A: The OVSASBLCR8 has reached end-of-life status. The OVSA1SBLCR8 is the active production equivalent from the same manufacturer, offering continued supply and support for this LED indication function.
