EFR5364X LED RED CLEAR 5MM ROUND T/H Equivalent & Substitute Parts

Part Overview

The EFR5364X is a red 5mm through-hole LED manufactured by Stanley Electric Co, designed for indication applications with a dominant wavelength of 626nm and peak wavelength of 635nm. This component is classified as obsolete, necessitating identification of active substitute parts for new designs and ongoing production requirements. The EFR5364X operates at a forward voltage of 1.9V with a test current of 20mA and delivers 1160mcd luminous intensity through a clear domed lens with a 35° viewing angle.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the EFR5364X are identified from the Everlight Electronics Co Ltd product line based on the following substitution criteria:

Primary Compatibility Parameters:

• Color: Red
• Lens Size: 5.00mm Dia (equivalent to 5mm T-1 3/4)
• Lens Transparency: Clear
• Lens Style: Round with Domed Top
• Mounting Type: Through Hole
• Package / Case: Radial
• Configuration: Standard
• Current - Test: 20mA

Secondary Compatibility Parameters:

• Voltage - Forward (Vf) (Typ): 2V (0.1V variance from 1.9V)
• Wavelength - Dominant: 624nm (within red spectrum range)
• Wavelength - Peak: 632nm (within red spectrum range)

The five substitute parts (383-2SURC/S400-A6, 383-2SURC/S400-A8, 383-2SURC/S530-A3, 383-2SURC/S530-A4, 383-2SURC/S530-A5) differ primarily in millicandela rating, ranging from 2500mcd to 12500mcd. All substitute parts are manufactured by Everlight Electronics Co Ltd and maintain active product status with ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Substitute Selection Based on Luminous Intensity Requirements:

The five Everlight Electronics Co Ltd substitute parts provide different brightness levels suitable for various application requirements:

• 383-2SURC/S530-A3 (2500mcd): Suitable for applications requiring moderate brightness with luminous intensity approximately 2.2 times the EFR5364X.

• 383-2SURC/S530-A4 (4000mcd): Provides increased brightness at approximately 3.4 times the EFR5364X intensity.

• 383-2SURC/S530-A5 (5000mcd): Delivers approximately 4.3 times the EFR5364X brightness level.

• 383-2SURC/S400-A6 (6300mcd): Offers approximately 5.4 times the EFR5364X intensity.

• 383-2SURC/S400-A8 (12500mcd): Provides maximum brightness at approximately 10.8 times the EFR5364X intensity.

Compliance and Product Status:

All substitute parts are manufactured by Everlight Electronics Co Ltd with active product status and ROHS3 compliance certification. The EFR5364X obsolete status necessitates transition to one of these active alternatives for continued component availability and regulatory compliance.

Electrical Parameter Considerations:

Forward voltage increases from 1.9V to 2V across all substitutes. Circuit designs must accommodate this 0.1V variance in series resistor calculations for current-limiting applications. All parts maintain identical 20mA test current specifications.

Optical Parameter Differences:

Substitute parts feature a narrower 6° viewing angle compared to the EFR5364X 35° viewing angle. Wavelength specifications remain within the red spectrum range (624nm dominant, 632nm peak) with minimal perceptual color shift from the original 626nm/635nm specification.

Mechanical Compatibility:

All substitute parts maintain 5mm through-hole radial package configuration with maximum height of 8.90mm, representing a 0.10mm increase from the EFR5364X 8.80mm specification. This variance remains within standard PCB design tolerances.

Frequently Asked Questions (FAQ)

Q: Can the Everlight 383-2SURC series parts directly replace the EFR5364X without circuit modification?

A: Direct mechanical and electrical substitution is possible with circuit design review. The 0.1V forward voltage increase (1.9V to 2V) requires recalculation of series resistor values in current-limiting circuits to maintain specified LED current. Optical performance differs due to narrower viewing angle (6° versus 35°) and higher brightness ratings.

Q: Which substitute part most closely matches the EFR5364X brightness level?

A: The 383-2SURC/S530-A3 at 2500mcd provides the lowest brightness among substitutes, approximately 2.2 times the EFR5364X 1160mcd rating. Applications requiring brightness closest to the original specification should select this part, though exact matching is not available.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All five Everlight Electronics Co Ltd substitute parts (383-2SURC/S400-A6, 383-2SURC/S400-A8, 383-2SURC/S530-A3, 383-2SURC/S530-A4, 383-2SURC/S530-A5) carry ROHS3 compliance certification. The original EFR5364X is REACH Unaffected.

Q: What is the impact of the narrower 6° viewing angle in substitute parts?

A: The reduction from 35° to 6° viewing angle concentrates light output into a narrower cone. Applications requiring wide-angle indication must account for this optical characteristic change. The higher millicandela ratings partially compensate for the narrower beam pattern in direct-view applications.

Q: Are the substitute parts available in the same packaging format?

A: Yes. All substitute parts maintain 5mm through-hole radial package configuration identical to the EFR5364X. Maximum height increases marginally from 8.80mm to 8.90mm, which remains compatible with standard PCB design specifications.

Q: What is the moisture sensitivity level for substitute parts?

A: All Everlight substitute parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage and handling. The original EFR5364X specifies Not Applicable for MSL.

Q: Can substitute parts be selected based on brightness requirements alone?

A: No. Selection must consider application-specific requirements including viewing angle, forward voltage tolerance in the circuit design, and wavelength specifications. The five substitute options provide brightness selection from 2500mcd to 12500mcd to accommodate different indication intensity requirements.
