SLA580BC4T3F Equivalent & Substitute Parts

Part Overview

The SLA580BC4T3F is a blue 470nm LED indicator manufactured by Rohm Semiconductor, designed for through-hole applications in discrete indication circuits. This component features a 5mm T-1 3/4 lens with 1500mcd brightness and a 3.2V forward voltage rating. The part is classified as obsolete, making identification of compatible substitutes essential for ongoing production and maintenance applications. Substitute parts must maintain functional equivalence across optical, electrical, and mechanical parameters while meeting current availability and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SLA580BC4T3F are identified based on the following critical parameters that determine functional compatibility:

• Optical Characteristics: Color (Blue), dominant wavelength (470nm), and lens configuration (5mm T-1 3/4 clear round domed top)
• Electrical Specifications: Forward voltage (Vf), test current (20mA), and brightness output (millicandela rating)
• Mechanical Compatibility: Through-hole radial package, physical dimensions, and mounting footprint
• Regulatory Compliance: RoHS3 compliance and REACH status

The LTL2T3TBK5 qualifies as a substitute based on matching optical lens specifications, identical mounting type, compatible electrical test parameters, and equivalent regulatory compliance. Variations in forward voltage (4.6V vs. 3.2V), brightness (1200mcd vs. 1500mcd), and viewing angle (30° vs. 10°) are within acceptable tolerance ranges for LED indicator applications and do not preclude substitution in standard indication circuits.

Parameter Comparison

Engineering Selection Recommendations

The LTL2T3TBK5 is suitable as a substitute for the obsolete SLA580BC4T3F based on the following factors:

• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring compatibility with current environmental and safety standards.
• Product Availability: The LTL2T3TBK5 is classified as active with 60,200 units in stock, providing reliable supply continuity compared to the obsolete SLA580BC4T3F.
• Mechanical Compatibility: Identical package configuration (T-1 3/4 radial through-hole), lens style, and maximum height (8.70mm) ensure direct footprint compatibility without PCB redesign.
• Optical and Electrical Equivalence: Matching dominant wavelength (470nm), lens configuration, and test current (20mA) maintain functional performance in indication circuits. The forward voltage differential (4.6V vs. 3.2V) and brightness variation (1200mcd vs. 1500mcd) are within acceptable ranges for standard LED indicator applications.

Frequently Asked Questions (FAQ)

Q: Can the LTL2T3TBK5 be used as a direct replacement without circuit modifications?

A: Yes, the LTL2T3TBK5 is mechanically and functionally compatible with the SLA580BC4T3F. Both parts share identical package dimensions, lens specifications, and test current ratings. The forward voltage difference (0.3V) may require minor resistor value adjustments in current-limiting circuits to maintain consistent brightness, but direct substitution is feasible in most applications.

Q: What is the significance of the viewing angle difference between these parts?

A: The SLA580BC4T3F has a 10° viewing angle, while the LTL2T3TBK5 has a 30° viewing angle. This means the substitute part provides a wider light distribution pattern. For applications requiring narrow-angle indication, this difference should be evaluated against specific design requirements.

Q: Are both parts compliant with current environmental regulations?

A: Yes, both the SLA580BC4T3F and LTL2T3TBK5 are ROHS3 compliant and REACH unaffected, meeting current environmental and safety standards for electronic components.

Q: Why is the brightness rating different between these parts?

A: The SLA580BC4T3F is rated at 1500mcd while the LTL2T3TBK5 is rated at 1200mcd. This 20% difference in brightness output is within acceptable tolerance for LED indicator applications. Selection should be based on specific illumination requirements for the intended application.

Q: What packaging options are available for the substitute part?

A: The LTL2T3TBK5 is supplied in bulk packaging, whereas the original SLA580BC4T3F information does not specify packaging format. Confirm packaging requirements with your procurement process.
