SLA-360LT3F Equivalent & Substitute Parts

Part Overview

The SLA-360LT3F is a red LED indication component manufactured by Rohm Semiconductor, designed for through-hole mounting applications. This part is classified as obsolete, making identification of suitable substitute components necessary for ongoing design support and procurement continuity. The component features a 3mm T-1 round lens with domed top configuration and operates at 1.75V forward voltage with a 68mcd brightness rating at 20mA test current.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLA-360LT3F is determined by the following critical parameters:

• Mounting Type: Through Hole (radial configuration required)
• Lens Size: 3mm T-1 form factor
• Color: Red indication
• Viewing Angle: 40° standard
• Compliance: ROHS3 Compliant, REACH Unaffected

The substitute part SLI-343V8RC3F meets these core mechanical and electrical compatibility criteria. Both components share identical mounting methodology, lens form factor, color specification, and regulatory compliance status. Variations in forward voltage (1.75V vs. 2.2V), brightness rating (68mcd vs. 330mcd), and wavelength characteristics (660nm vs. 630nm) are within acceptable substitution parameters for red LED indication applications, provided circuit design accommodates the electrical differences.

Parameter Comparison

Engineering Selection Recommendations

The SLI-343V8RC3F is an active product from Rohm Semiconductor and represents a viable substitute for the obsolete SLA-360LT3F. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity.

Circuit design modifications are required to accommodate the 0.45V increase in forward voltage (1.75V to 2.2V). Current-limiting resistor values must be recalculated to maintain proper LED operation at the specified 20mA test current. The increased brightness rating (330mcd vs. 68mcd) provides enhanced visibility margin for indication applications.

Physical dimensions show minimal variation: the substitute part height increases by 0.35mm (5.60mm vs. 5.25mm) and lens diameter increases by 0.10mm (3.10mm vs. 3mm T-1). These dimensional changes remain within standard through-hole PCB layout tolerances for 3mm LED form factors.

Frequently Asked Questions (FAQ)

Q: Can the SLI-343V8RC3F be used as a direct drop-in replacement for the SLA-360LT3F?

A: Physical mounting is compatible due to shared radial through-hole configuration and 3mm T-1 form factor. However, circuit design modifications are required due to the 0.45V forward voltage difference. Current-limiting resistor values must be recalculated to maintain proper LED operation.

Q: What are the key differences between these two parts?

A: The primary differences are forward voltage (1.75V vs. 2.2V), brightness rating (68mcd vs. 330mcd), wavelength (660nm vs. 630nm), and product status (obsolete vs. active). Mechanical form factor, mounting type, viewing angle, and compliance certifications are equivalent.

Q: Does the increased brightness of the SLI-343V8RC3F affect compatibility?

A: The higher brightness rating (330mcd) is a performance enhancement for indication applications. Circuit design must account for the increased forward voltage to prevent over-current conditions. Proper current-limiting resistor selection ensures safe operation.

Q: Are there packaging differences between these components?

A: The SLA-360LT3F is supplied in standard packaging, while the SLI-343V8RC3F is supplied in bulk packaging. Both maintain identical through-hole radial configuration suitable for PCB assembly.

Q: What compliance certifications apply to the substitute part?

A: The SLI-343V8RC3F maintains ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the original SLA-360LT3F.
