SLR-56MG3F Equivalent & Substitute Parts

Part Overview

The SLR-56MG3F is a green diffused T-1 3/4 through-hole LED manufactured by Rohm Semiconductor, designed for indication applications with a dominant wavelength of 572nm. This part is classified as Not For New Designs, making identification of active equivalent components essential for ongoing production and maintenance applications. Substitute parts must maintain compatibility across electrical characteristics, mechanical form factor, and regulatory compliance to ensure direct interchangeability in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLR-56MG3F is determined by strict adherence to the following parameters:

Critical Parameters (Must Match):

• Lens Size: 5mm, T-1 3/4
• Mounting Type: Through Hole
• Color: Green
• Voltage - Forward (Vf) (Typ): 2.1V
• Viewing Angle: 40°
• Package / Case: Radial
• RoHS Status: ROHS3 Compliant

Variable Parameters (Allowed to Differ):

• Lens Transparency (Diffused or Clear)
• Millicandela Rating
• Current - Test
• Wavelength - Dominant / Peak
• Height (Max)
• Product Status

The substitute parts listed below satisfy all critical parameters while maintaining functional equivalence for indication applications.

Engineering Selection Recommendations

All three substitute parts (5GD-F, HLMP-3568, LTL2R3KG) meet the critical electrical and mechanical requirements for direct substitution with the SLR-56MG3F. Selection should be based on the following considerations:

5GD-F (Bivar Inc.): Active product status with diffused lens matching the original specification. Higher millicandela rating (25mcd) and increased test current (20mA) provide enhanced brightness for indication applications requiring greater visibility.

HLMP-3568 (Broadcom Limited): Active product status with clear lens transparency, differing from the original diffused specification. Lower millicandela rating (10.6mcd) and matching test current (10mA) provide reduced brightness output. Compact height (6.35mm) offers space-constrained PCB layouts.

LTL2R3KG (Lite-On Inc.): Active product status with diffused lens matching the original specification. Significantly higher millicandela rating (180mcd) and increased test current (20mA) deliver maximum brightness for high-visibility indication. REACH Affected status requires compliance verification for regulated applications.

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory and environmental compatibility.

Frequently Asked Questions (FAQ)

Q: Can HLMP-3568 be used as a direct replacement despite having a clear lens instead of diffused?

A: HLMP-3568 meets all critical electrical and mechanical parameters required for substitution. The clear lens transparency differs from the original diffused specification, resulting in a more focused light output. Application requirements determine acceptability; verify that the altered light distribution does not compromise intended indication visibility or aesthetics.

Q: What is the impact of different millicandela ratings among substitute parts?

A: Millicandela rating determines LED brightness output. The SLR-56MG3F operates at 16mcd. Substitute parts range from 10.6mcd (HLMP-3568) to 180mcd (LTL2R3KG). Selection should align with application visibility requirements and power budget constraints. Higher brightness increases power consumption and heat generation.

Q: Are all substitute parts suitable for new production?

A: 5GD-F, HLMP-3568, and LTL2R3KG all carry Active product status, making them suitable for ongoing production and new designs. The original SLR-56MG3F is classified as Not For New Designs, necessitating substitution for future applications.

Q: Does the height difference between substitute parts affect PCB layout compatibility?

A: Height variations range from 6.35mm (HLMP-3568) to 8.90mm (SLR-56MG3F). Verify PCB clearance and mechanical constraints before selection. Compact designs may benefit from HLMP-3568, while standard layouts accommodate all options.

Q: What compliance considerations apply to LTL2R3KG?

A: LTL2R3KG carries REACH Affected status, requiring compliance verification for applications subject to REACH regulations. All substitute parts maintain ROHS3 compliance and EAR99 export classification matching the original part.
