Substitute Part Grouping Explanation

Substitution of the 150283FS73103 is permissible with alternative Würth Elektronik WL-SMTW series components based on the following criteria:

Mandatory Matching Parameters:

• Manufacturer: Würth Elektronik
• Series: WL-SMTW
• Package / Case: 1411 (3528 Metric)
• Mounting Type: Surface Mount
• Color: Red
• Lens Transparency: Clear
• Voltage - Forward (Vf) (Typ): 2.2V
• Current - Test: 150mA
• Viewing Angle: 120°
• Size / Dimension: 3.50mm L x 2.80mm W
• Height (Max): 0.85mm
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 3 (168 Hours)
• Packaging: Tape & Reel (TR)

Variable Parameters (Substitution Basis):

• Wavelength - Peak: 730nm (150283FS73103), 660nm (150283HS73103), 629nm (150283RS73103)
• Wavelength - Dominant: Not specified (150283FS73103), Not specified (150283HS73103), 620nm (150283RS73103)

All substitute parts maintain identical electrical performance, mechanical dimensions, and compliance certifications. Substitution is determined solely by wavelength requirements of the application.

Parameter Comparison

Engineering Selection Recommendations

All three parts—150283FS73103, 150283HS73103, and 150283RS73103—are active products from Würth Elektronik within the WL-SMTW series. Each maintains full ROHS3 compliance and REACH unaffected status, ensuring regulatory conformance across all applications.

Selection between these parts is determined exclusively by wavelength requirements:

• 150283FS73103 (730nm peak wavelength): For applications requiring far-red spectrum indication
• 150283HS73103 (660nm peak wavelength): For applications requiring standard red spectrum indication
• 150283RS73103 (620nm dominant, 629nm peak wavelength): For applications requiring orange-red spectrum indication

All parts share identical electrical characteristics (2.2V forward voltage, 150mA test current), mechanical dimensions (3.50mm × 2.80mm × 0.85mm maximum height), and packaging specifications (3528 metric, Tape & Reel). Substitution between these parts is valid when the application wavelength specification permits the alternative wavelength range.

Frequently Asked Questions (FAQ)

Q: Can 150283HS73103 be used as a direct replacement for 150283FS73103?

A: Yes, provided the application wavelength specification permits substitution. Both parts share identical electrical performance (2.2V forward voltage, 150mA test current), mechanical dimensions, and compliance certifications. The difference is wavelength: 150283FS73103 operates at 730nm peak wavelength, while 150283HS73103 operates at 660nm peak wavelength. Substitution is valid only if the circuit design does not require the specific 730nm wavelength.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts—150283FS73103, 150283HS73103, and 150283RS73103—use the identical 1411 (3528 metric) package with dimensions of 3.50mm length × 2.80mm width × 0.85mm maximum height. They are mechanically interchangeable on the same PCB layout.

Q: What is the difference between wavelength-peak and wavelength-dominant specifications?

A: Wavelength-peak indicates the spectral output at maximum intensity. Wavelength-dominant indicates the perceived color wavelength. For 150283RS73103, the dominant wavelength is specified as 620nm with a peak wavelength of 629nm. For 150283FS73103 and 150283HS73103, only peak wavelength values are provided.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All three parts maintain Moisture Sensitivity Level (MSL) 3 with a 168-hour floor life specification. Handling and storage requirements are identical across all substitute parts.

Q: Are there inventory differences between the substitute parts?

A: Yes. Current inventory levels differ: 150283FS73103 has 4,356 pieces, 150283HS73103 has 5,386 pieces, and 150283RS73103 has 2,654 pieces in stock. Inventory availability should be confirmed at the time of procurement.

Q: Can these parts be used interchangeably in production without design changes?

A: Mechanical and electrical interchangeability is confirmed. However, substitution requires verification that the application wavelength specification permits the alternative wavelength range. If the circuit design or application specifies a particular wavelength requirement, substitution is valid only if the alternative part's wavelength falls within the acceptable range.
