Color: Orange wavelength range (605nm dominant)
Lens transparency: Clear
Forward voltage: 1.9V nominal
Test current: 20mA
Millicandela rating: Comparable brightness output

Substitution Logic: Parts are grouped as direct substitutes when they maintain the same lens size, mounting type, color, and transparency while operating within the same voltage and current parameters. Parts with identical wavelength specifications (605nm dominant) and similar luminous intensity ratings are considered primary equivalents. Parts with different colors (yellow) or significantly different electrical parameters are listed as secondary alternatives only when they share the same mechanical form factor and can function in applications where color variation is acceptable.

Engineering Selection Recommendations

Primary Orange LED Substitutes (Direct Color Match):

HLMP-C423-L0002 (Broadcom Limited) is an active product offering orange LED indication with identical 1.9V forward voltage and 20mA test current. This part maintains the 605nm dominant wavelength specification and clear lens transparency. The primary difference is reduced luminous intensity (170mcd versus 580mcd) and narrower viewing angle (25° versus 45°). This substitute is suitable for applications where the reduced brightness is acceptable within circuit design parameters. RoHS3 compliance and unlimited moisture sensitivity rating support long-term reliability.

SLI-560DT3F (Rohm Semiconductor) provides orange LED indication with 1.9V forward voltage and 20mA test current, matching the FA5365S electrical profile. This part delivers significantly higher luminous intensity (1000mcd) with 611nm dominant wavelength, representing a minor wavelength shift within the orange spectrum. The product status is classified as "Not For New Designs," limiting its application to legacy system maintenance only.

SLR-56DC3F and SLR-56DCT32 (Rohm Semiconductor, SLR-56 Series) are active orange LED products with 605nm dominant wavelength matching the FA5365S. Both parts operate at 2V forward voltage with 10mA test current, representing a 0.1V increase and 50% current reduction compared to the original specification. Luminous intensity is significantly lower (25mcd). These parts are suitable for applications where reduced brightness and lower current consumption are acceptable design modifications. The DCT32 variant uses tape and box packaging, while DC3F uses bulk packaging.

Secondary Yellow LED Alternatives (Color Variation):

Yellow LED substitutes are listed for applications where color variation from orange to yellow is functionally acceptable. These parts share the same 5mm T-1 3/4 through-hole form factor but operate at higher forward voltages (2.0V to 2.1V) and reduced test currents (10mA).

LTL-307YE (Lite-On Inc.) is an active yellow LED with 588nm dominant wavelength, 2.1V forward voltage, and 20mA test current. This part maintains the 20mA test current specification while offering 40mcd luminous intensity. Clear lens transparency and 40° viewing angle provide comparable optical characteristics to the FA5365S.

SLR-56YC3F and SLR-56YCT32 (Rohm Semiconductor, SLR-56 Series) are active yellow LED products with 587nm dominant wavelength, 2.1V forward voltage, and 10mA test current. Both parts deliver 25mcd luminous intensity with 40° viewing angle. The YCT32 variant uses tape and box packaging for automated assembly applications.

Z-212Y (JKL Components Corp.) is an active yellow LED with 590nm peak wavelength, 2.1V forward voltage, and 10mA test current. This part features a significantly taller profile (13.50mm maximum height) and narrow viewing angle (16°), limiting its application to specific mechanical and optical requirements.

Compliance and Availability:

All recommended active substitutes maintain RoHS3 compliance and REACH unaffected status. Inventory availability ranges from 757 to 22,950 pieces across substitute options, supporting production requirements. The FA5365S original part maintains 784 pieces in stock as obsolete inventory.

Frequently Asked Questions (FAQ)

Q: Can HLMP-C423-L0002 directly replace FA5365S in all applications?

A: HLMP-C423-L0002 maintains identical forward voltage (1.9V), test current (20mA), color (orange), and wavelength (605nm) specifications. The primary difference is reduced luminous intensity (170mcd versus 580mcd) and narrower viewing angle (25° versus 45°). Direct replacement is possible only in applications where the reduced brightness output does not compromise circuit function or visual indication requirements. Circuit design review is necessary to confirm acceptable performance.

Q: What is the difference between SLR-56DC3F and SLR-56DCT32?

A: Both parts are electrically and optically identical orange LEDs from the Rohm Semiconductor SLR-56 series. The primary difference is packaging format: DC3F uses bulk packaging for manual assembly, while DCT32 uses tape and box packaging for automated pick-and-place assembly. Electrical specifications, luminous intensity, wavelength, and form factor are identical.

Q: Why do yellow LED substitutes have different forward voltage than the orange FA5365S?

A: Yellow LEDs inherently require higher forward voltage (2.0V to 2.1V) compared to orange LEDs (1.9V) due to the different semiconductor bandgap energy required to produce yellow wavelengths (585nm to 590nm) versus orange (605nm to 611nm). This is a fundamental material property and cannot be changed. Circuit design must accommodate the voltage difference if yellow substitutes are selected.

Q: Is SLI-560DT3F suitable for new product designs?

A: No. SLI-560DT3F is classified as "Not For New Designs" by Rohm Semiconductor. This part is available only for legacy system maintenance and repair applications. New product designs must select from active status parts: HLMP-C423-L0002, SLR-56DC3F, SLR-56DCT32, or yellow alternatives.

Q: What viewing angle difference exists between FA5365S and substitute parts?

A: FA5365S specifies 45° viewing angle. HLMP-C423-L0002 provides 25° (narrower), SLI-560DT3F and SLR-56 series provide 40° (slightly narrower), and Z-212Y provides 16° (significantly narrower). Narrower viewing angles concentrate light output in a smaller cone, affecting visibility from off-axis positions. Application requirements determine acceptable viewing angle specifications.

Q: Can I use 10mA test current parts as direct replacements for 20mA parts?

A: Parts specified for 10mA test current (SLR-56 series, HLMP-3451 variants, LTL-307YE, Z-212Y) deliver reduced luminous intensity compared to 20mA rated parts. Direct replacement requires circuit design modification to increase drive current to 20mA if original brightness output is required. Alternatively, reduced brightness may be acceptable depending on application requirements. Circuit design review is necessary.

Q: What is the height difference between FA5365S and substitute parts?

A: FA5365S maximum height is 7.80mm. HLMP-C423-L0002 is 8.91mm (1.11mm taller), SLI-560DT3F is 7.70mm (0.10mm shorter), SLR-56 series parts are 8.90mm (1.10mm taller), LTL-307YE is 8.60mm (0.80mm taller), and Z-212Y is 13.50mm (5.70mm taller). Height differences may affect PCB layout and mechanical clearance. Verify physical fit in target application before selection.

Q: Are all substitute parts RoHS3 compliant?

A: All active status substitute parts listed are RoHS3 compliant. SLI-560DT3F (Not For New Designs status) is also RoHS3 compliant. The original FA5365S does not specify RoHS status. All parts maintain REACH unaffected status and EAR99 export classification.
