SLR-56MGT32 Equivalent & Substitute Parts

Part Overview

The SLR-56MGT32 is a green diffused LED indicator manufactured by Rohm Semiconductor, designed for through-hole mounting applications. This T-1 3/4 form factor component operates at 2.1V forward voltage and delivers 16mcd luminous intensity at 10mA test current. The product is currently active and widely used in electronic indication circuits requiring standard green wavelength output at 572nm. Substitute parts may be required due to inventory availability, lead time considerations, or specific application requirements within the allowed electrical and mechanical parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLR-56MGT32 is determined by strict adherence to the following critical parameters:

• Color and Wavelength: Green color with dominant wavelength of 572nm
• Electrical Characteristics: Forward voltage of 2.1V (typical)
• Mechanical Form Factor: T-1 3/4 through-hole radial package with 5mm lens diameter
• Optical Properties: Diffused lens transparency with 40° viewing angle
• Compliance: ROHS3 compliance and EAR99 ECCN classification

The substitute part LTL2R3KG from Lite-On Inc. meets all critical substitution criteria within these allowed parameters. Both components share identical forward voltage, wavelength specification, lens transparency, viewing angle, and mechanical package configuration. Differences in millicandela rating and test current reflect normal manufacturing variations within the green LED indicator category and do not preclude substitution in standard indication applications.

Parameter Comparison

Engineering Selection Recommendations

Both the SLR-56MGT32 and LTL2R3KG are active products with ROHS3 compliance and EAR99 classification, meeting current regulatory requirements. Selection between these components should be based on:

• Inventory Availability: SLR-56MGT32 has 1056 pcs in stock; LTL2R3KG has 10043 pcs in stock
• Packaging Format: SLR-56MGT32 is supplied in Cut Tape; LTL2R3KG is supplied in Bulk
• Mechanical Fit: Both components fit the T-1 3/4 through-hole footprint with compatible radial package geometry and similar maximum heights (8.90mm vs 8.70mm)
• Electrical Compatibility: Identical forward voltage of 2.1V ensures direct circuit compatibility

The LTL2R3KG offers higher luminous intensity (180mcd vs 16mcd) and operates at higher test current (20mA vs 10mA), making it suitable for applications requiring increased brightness within the same form factor and electrical operating point.

Frequently Asked Questions (FAQ)

Q: Can LTL2R3KG directly replace SLR-56MGT32 in existing PCB designs?

A: Yes. Both components share identical T-1 3/4 radial through-hole package geometry, forward voltage (2.1V), wavelength (572nm), and viewing angle (40°). PCB footprints and circuit connections are compatible without modification.

Q: What is the difference in brightness between these two parts?

A: The LTL2R3KG operates at 180mcd compared to the SLR-56MGT32 at 16mcd. This difference reflects the higher test current specification (20mA vs 10mA) for the Lite-On component. Both are suitable for standard indication applications within their respective operating parameters.

Q: Are there compliance differences between the two parts?

A: Both components are ROHS3 compliant and classified as EAR99. The SLR-56MGT32 is REACH Unaffected; the LTL2R3KG is REACH Affected. Both meet current regulatory requirements for electronic component use.

Q: What packaging considerations apply to substitution?

A: The SLR-56MGT32 is supplied in Cut Tape packaging; the LTL2R3KG is supplied in Bulk. This affects handling and assembly processes but does not impact electrical or mechanical compatibility.

Q: Are the physical dimensions identical?

A: Maximum heights differ slightly: SLR-56MGT32 is 8.90mm; LTL2R3KG is 8.70mm. Both fit within standard T-1 3/4 through-hole mounting specifications. Lens diameter is 5mm for both components.
