Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLH-56MG3F is determined by the following critical parameters:

• Color: Green
• Lens Transparency: Diffused
• Lens Size: 5mm, T-1 3/4
• Voltage - Forward (Vf): 2.1V
• Mounting Type: Through Hole
• Package / Case: Radial
• RoHS Status: ROHS3 Compliant

The SLR-56MG3F qualifies as a substitute based on matching all critical parameters. Variations in millicandela rating, test current, and peak wavelength are within acceptable tolerance ranges for green LED indication applications where the primary functional requirement is visual indication rather than precise luminous intensity specification.

Parameter Comparison

Engineering Selection Recommendations

The SLR-56MG3F serves as a direct substitute for the SLH-56MG3F in through-hole green LED indication circuits. Both components maintain ROHS3 compliance and identical forward voltage characteristics at 2.1V, ensuring circuit compatibility without modification to current-limiting resistor calculations.

The SLR-56MG3F operates at reduced test current (10mA versus 20mA) and lower millicandela output (16mcd versus 100mcd). Circuit designers must evaluate whether the reduced brightness level meets application requirements. The wavelength shift from 563nm to 572nm remains within the green spectrum and produces no perceptible color difference in typical indication applications.

The SLR-56MG3F is classified as Not For New Designs, indicating limited future availability. For new product development, alternative green LED components with active product status should be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the SLR-56MG3F directly replace the SLH-56MG3F in existing circuit boards?

A: Yes, the SLR-56MG3F is mechanically and electrically compatible. Both components feature identical 5mm T-1 3/4 through-hole radial packages, 2.1V forward voltage, and diffused green lens configuration. No PCB modifications are required.

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

A: The SLH-56MG3F produces 100mcd while the SLR-56MG3F produces 16mcd. The SLH-56MG3F is significantly brighter. Applications requiring high-visibility indication should account for this 84mcd reduction when substituting.

Q: Are there differences in wavelength between these parts?

A: The SLH-56MG3F has a peak wavelength of 563nm while the SLR-56MG3F operates at 572nm. Both wavelengths fall within the green spectrum and produce visually equivalent green indication in standard applications.

Q: What is the height difference between these components?

A: The SLH-56MG3F has a maximum height of 9.70mm while the SLR-56MG3F measures 8.90mm maximum height. The 0.80mm difference is negligible for most through-hole applications and does not affect circuit board layout compatibility.

Q: Do both parts meet current compliance standards?

A: Yes, both the SLH-56MG3F and SLR-56MG3F are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What is the significance of the product status difference?

A: The SLH-56MG3F is classified as Obsolete, indicating discontinued production. The SLR-56MG3F is classified as Not For New Designs, indicating limited availability and no recommendation for new product development. Both statuses indicate supply constraints and the need for long-term alternative component strategies.
