SLI-560DT3F Equivalent & Substitute Parts

Part Overview

The SLI-560DT3F is an orange LED indicator manufactured by Rohm Semiconductor, designed for through-hole applications in T-1 3/4 form factor. This part is classified as "Not For New Designs," making identification of functionally equivalent alternatives essential for ongoing production support and design flexibility. The orange 611nm wavelength and 1000mcd brightness rating define its primary application scope. Substitute parts must maintain compatibility with through-hole mounting, radial package configuration, and the electrical operating parameters specified for this LED category.

Key Parameters

Substitute Part Grouping Explanation

The substitute parts listed for SLI-560DT3F are provided based on the manufacturer's original substitution data. However, a critical parameter mismatch exists: all five substitute parts are yellow LEDs (580–591nm wavelength range), while the main part is an orange LED (611nm). This represents a significant optical and functional difference.

Substitution logic for LED indicators is determined by:

• Color / Wavelength: Dominant wavelength determines visual appearance and application suitability
• Brightness (Millicandela Rating): Determines visibility in target application
• Forward Voltage (Vf): Affects circuit design and current-limiting resistor selection
• Lens Size and Mounting Type: Ensures mechanical compatibility with PCB and enclosure
• Viewing Angle: Determines light distribution pattern
• Product Status and Compliance: Active status and RoHS3 compliance ensure ongoing availability and regulatory alignment

The provided substitute list includes parts with significantly different brightness levels (140mcd to 7400mcd) and viewing angles (15° to 30°), indicating these are not direct optical equivalents but rather alternative indicator solutions available from the same or compatible form factors.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are classified as Active products with ROHS3 compliance, ensuring regulatory alignment and ongoing manufacturing support. The primary consideration for selection is the color mismatch: the SLI-560DT3F is an orange indicator, while all substitutes are yellow indicators. This distinction affects visual perception and application suitability.

For applications requiring orange indication specifically, no direct substitute exists within the provided list. For applications where yellow indication is acceptable as an alternative:

• LTL2R3KSK (Lite-On Inc.) offers the closest brightness match to the main part at 1150mcd with a 30° viewing angle, maintaining T-1 3/4 form factor and 8.70mm height.
• OVLFY3C7 (TT Electronics/Optek Technology) provides higher brightness at 7400mcd for applications requiring enhanced visibility, with 30° viewing angle and compatible form factor.
• 7383-Y7C3-AQSB-P-MS (Everlight Electronics Co Ltd) offers the highest brightness at 4500mcd but with maximum height of 12.60mm, requiring verification of PCB clearance.

Forward voltage differences (1.9V main part vs. 2.0–2.2V substitutes) require circuit resistor recalculation to maintain 20mA test current.

Frequently Asked Questions (FAQ)

Q: Can these substitute parts directly replace the SLI-560DT3F without circuit modification?

A: No. The substitute parts are yellow LEDs with different forward voltages (2.0–2.2V vs. 1.9V). Current-limiting resistor values must be recalculated to maintain proper operating current. Additionally, the color change from orange to yellow affects visual indication and may not be suitable for all applications.

Q: Why are all substitute parts yellow when the main part is orange?

A: The substitute list is provided based on manufacturer data. Yellow LEDs in the 5mm T-1 3/4 through-hole form factor with comparable brightness and electrical characteristics are the available alternatives. If orange indication is required, alternative sourcing or design revision may be necessary.

Q: Which substitute offers the best brightness match?

A: LTL2R3KSK at 1150mcd is closest to the main part's 1000mcd rating. OVLFY3C7 at 7400mcd provides significantly higher brightness for applications requiring enhanced visibility.

Q: Are there mechanical compatibility concerns?

A: Most substitutes maintain the 5mm T-1 3/4 lens size and radial package. However, 7383-Y7C3-AQSB-P-MS has a maximum height of 12.60mm compared to 7.70mm for the main part. Verify PCB and enclosure clearance before selection. 5219466F has a slightly smaller lens diameter (4.83mm) and may require mechanical verification.

Q: Do all substitutes meet compliance requirements?

A: Yes. All substitute parts are ROHS3 compliant and classified as Active products, ensuring regulatory alignment and ongoing availability.

Q: How does viewing angle affect substitution?

A: The main part has a 40° viewing angle. Substitutes range from 15° to 30°. Narrower angles concentrate light intensity but reduce peripheral visibility. Verify the application's viewing geometry before selection.
