SLA560BC7T3F Equivalent & Substitute Parts

Part Overview

The SLA560BC7T3F is a blue LED indicator manufactured by Rohm Semiconductor, designed for through-hole applications with a 5mm T-1 3/4 form factor. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The part delivers 680mcd luminous intensity at 3.2V forward voltage with a 40° viewing angle, suitable for standard indication circuits requiring discrete blue light output at 470nm wavelength.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLA560BC7T3F is determined by the following critical parameters:

• Color: Blue (required match)
• Lens Size: 5mm, T-1 3/4 (required match for mechanical fit)
• Mounting Type: Through Hole (required match for PCB compatibility)
• Lens Transparency: Clear (required match for optical consistency)
• Package / Case: Radial (required match for lead configuration)
• Voltage - Forward (Vf): 3.2V nominal (acceptable tolerance range for circuit compatibility)
• Current - Test: 20mA (standard test condition)
• RoHS and REACH Compliance: ROHS3 Compliant and REACH Unaffected (regulatory requirement match)

The two identified substitute parts meet these core criteria while maintaining active product status, ensuring availability and ongoing manufacturer support.

Parameter Comparison

Engineering Selection Recommendations

CMD383UBC/H2 (Visual Communications Company - VCC): This substitute maintains active product status and full regulatory compliance. The forward voltage is elevated at 3.8V compared to the 3.2V nominal of the SLA560BC7T3F, requiring circuit verification to confirm acceptable operation within existing current-limiting resistor designs. Luminous intensity is comparable at 630mcd. The narrower 30° viewing angle differs from the original 40°, affecting light distribution characteristics. Height specification of 8.61mm exceeds the original 7.70mm, requiring PCB clearance validation.

OVLLB8C7 (TT Electronics/Optek Technology): This substitute provides the closest electrical match with identical 3.2V forward voltage and 470nm dominant wavelength. Active product status ensures continued availability. The 440mcd luminous intensity is lower than the original 680mcd, representing a 35% reduction in light output. The significantly wider 85° viewing angle provides broader light distribution compared to the original 40°. The flat-top lens style differs from the domed-top original. Height of 6.80mm is lower than the original specification, offering improved PCB clearance.

Both substitutes satisfy core mechanical and regulatory requirements. Selection depends on circuit tolerance for voltage variation and application requirements for luminous intensity and viewing angle characteristics.

Frequently Asked Questions (FAQ)

Q: Can CMD383UBC/H2 be used as a direct replacement for SLA560BC7T3F?

A: CMD383UBC/H2 meets the core mechanical and regulatory requirements for substitution. However, the 3.8V forward voltage requires circuit verification. If the original design uses a fixed current-limiting resistor calculated for 3.2V operation, the higher voltage will reduce LED current and light output. Resistor recalculation may be necessary.

Q: What is the primary difference between OVLLB8C7 and the original SLA560BC7T3F?

A: OVLLB8C7 matches the 3.2V forward voltage and 470nm wavelength exactly. The main differences are reduced luminous intensity (440mcd versus 680mcd) and a significantly wider viewing angle (85° versus 40°). The flat-top lens replaces the domed-top design. These differences affect light output brightness and distribution pattern.

Q: Are there mechanical compatibility concerns with these substitutes?

A: All three parts use the 5mm T-1 3/4 form factor with radial through-hole mounting, ensuring PCB footprint compatibility. Height variations exist: CMD383UBC/H2 at 8.61mm (0.91mm taller) and OVLLB8C7 at 6.80mm (0.90mm shorter). Verify clearance in applications with height constraints.

Q: Do both substitutes meet regulatory requirements?

A: Yes. Both CMD383UBC/H2 and OVLLB8C7 are ROHS3 Compliant and REACH Unaffected, matching the original part's regulatory status.

Q: Which substitute is recommended for brightness-critical applications?

A: CMD383UBC/H2 provides the closest luminous intensity at 630mcd, compared to the original 680mcd. OVLLB8C7 at 440mcd represents a significant reduction and is suitable only for applications where lower brightness is acceptable or where the wider viewing angle provides compensating benefit.

Q: Can viewing angle differences affect circuit performance?

A: Viewing angle affects light distribution but not electrical circuit operation. CMD383UBC/H2 with a narrower 30° angle concentrates light in a tighter beam. OVLLB8C7 with an 85° angle distributes light broadly. Application requirements determine which is appropriate—narrow angles for focused indication, wide angles for omnidirectional visibility.
