EFA5365S Orange LED 5mm Through-Hole Equivalent & Substitute Parts

Part Overview

The EFA5365S is a 5mm through-hole orange LED manufactured by Stanley Electric Co, designed for discrete LED indication applications. This component operates at 1.9V forward voltage with a 1160mcd brightness rating and 605nm dominant wavelength. The product is classified as obsolete, making equivalent and substitute parts necessary for ongoing production, maintenance, and new design considerations where orange LED indication functionality is required in 5mm T-1 3/4 form factor applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EFA5365S is determined by the following critical parameters:

Primary Compatibility Criteria:

• Color: Orange
• Lens Size: 5mm, T-1 3/4
• Mounting Type: Through Hole
• Package / Case: Radial
• Lens Transparency: Clear
• Lens Style: Round with Domed Top

Secondary Electrical Compatibility Criteria:

• Voltage - Forward (Vf) Typical: 1.9V to 2.0V range
• Current - Test: 20mA
• Wavelength - Dominant: 605nm to 611nm range (orange spectrum)

Acceptable Variation Parameters:

• Millicandela Rating: Brightness may vary based on application requirements
• Viewing Angle: May differ based on optical design requirements
• Height (Max): Minor variations acceptable within mechanical constraints

Substitute parts must maintain compatibility across all primary criteria and operate within the secondary electrical range. Parts that deviate in color, lens size, mounting type, or package configuration are not suitable substitutes.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Obsolete Product Continuation):

HLMP-EJ30-NR0DD (Broadcom Limited) provides the closest electrical and optical match to the EFA5365S. This part maintains 605nm dominant wavelength, 1.98V forward voltage within acceptable tolerance, and identical 5mm T-1 3/4 form factor. The part is currently in active production status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. Inventory of 19,741 units is available.

For New Design Applications:

SLI-580DT3F (Rohm Semiconductor) is recommended for applications requiring higher brightness output (5000mcd versus 1160mcd). This part maintains 605nm wavelength matching and 1.9V forward voltage identical to the original specification. Active product status and ROHS3 compliance support new design qualification. The narrower 10° viewing angle suits applications requiring concentrated light output.

For Brightness-Constrained Applications:

SLI-560DT3F (Rohm Semiconductor) operates at 1000mcd brightness, suitable for applications where the original 1160mcd output exceeds requirements. This part maintains 1.9V forward voltage and 5mm T-1 3/4 form factor. Note: Product status is "Not For New Designs," limiting use to legacy system maintenance only.

For Voltage-Tolerant Designs:

WP7113SET (Kingbright) operates at 2.0V forward voltage with 2200mcd brightness. This part is suitable for applications with voltage supply headroom accommodating the 0.1V increase. Active product status and ROHS3 compliance support both replacement and new design applications.

Regulatory and Compliance Considerations:

All recommended substitute parts maintain REACH Unaffected and EAR99 ECCN classifications, matching the original EFA5365S regulatory profile. ROHS3 compliance is confirmed for all active-status alternatives, ensuring compatibility with current environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can SLI-580YT3F substitute for EFA5365S?

A: No. SLI-580YT3F is a yellow LED (587nm wavelength) and does not meet the orange color requirement (605nm minimum). Color is a primary compatibility criterion and cannot be substituted.

Q: What is the maximum acceptable forward voltage variation?

A: The EFA5365S operates at 1.9V. Substitute parts operating at 1.98V to 2.0V are acceptable within standard LED manufacturing tolerances. Circuit designs must accommodate this range through appropriate current-limiting resistor selection.

Q: Does viewing angle affect substitution eligibility?

A: Viewing angle is an acceptable variation parameter. The EFA5365S specifies 45°, while substitutes range from 10° to 40°. Selection depends on application requirements. Narrower angles concentrate light output; wider angles distribute light across a broader area.

Q: Are packaging format differences significant?

A: Yes. The EFA5365S requires 5mm T-1 3/4 through-hole radial package. All listed substitutes maintain this form factor. Surface-mount or different through-hole sizes are not compatible.

Q: Why is SLI-580DT3F listed as a substitute despite 5000mcd brightness versus 1160mcd?

A: Millicandela rating is an acceptable variation parameter. Higher brightness does not prevent substitution if the application circuit can tolerate increased light output. Applications requiring exact brightness matching must implement optical filtering or current reduction.

Q: What is the significance of "Not For New Designs" status?

A: Parts marked "Not For New Designs" (such as SLI-560DT3F) are suitable for replacement in existing systems but should not be selected for new product development. These parts may have limited future availability or planned discontinuation.

Q: Can I use HLMP-EJ37-R0PDD if viewing angle is not specified?

A: Yes. HLMP-EJ37-R0PDD meets all primary compatibility criteria. The unspecified viewing angle does not prevent substitution; however, optical performance should be validated in the target application if viewing angle is a critical parameter.

Q: Are there inventory considerations for substitute selection?

A: Yes. HLMP-EJ30-NR0DD has 19,741 units in stock, providing long-term availability assurance. SLI-580DT3F has 1,902 units, and HLMP-EJ37-R0PDD has 1,003 units. For high-volume production, inventory levels should influence supplier selection.

Q: Does lens color (orange versus colorless) affect optical performance?

A: Lens color affects light transmission characteristics. EFA5365S has an orange lens; HLMP-EJ30-NR0DD has a colorless lens. Both emit orange light at the specified wavelength. The colorless lens may produce slightly different color saturation in the emitted light. Application requirements determine acceptability.
